They eat seals and fish.(Length: 2 min. 23 sec.)A. Write down the name of the animal beings described in each case.1) elephants2) chimpanzees3) giraffes4) penguins5) kangaroos6) zebras7) polar bearsB. Complete the following sentences with what you hear on the tape.1) They live in Africa and India. They have four legs and a tail.2) Their arms are very long and they have big ears.TipsIn case the students don't know some of the English names for these animals, they may give the names in Chinese. And then get them practise saying them in English. Alternatively, you could elicit/ introduce such animal names as chimpanzee, penguin, zebra and kangaroo.The fastest animal on land is the cheetah. It can run at a speed of about 100 kilometres an hour. The fastest bird in the world can fly at 170 km/h, and the fastest fish can swim at more than 100 km/h.Human beings are not very fast. The fastest man in the world can only run at about 40 km/h. Many animals can run faster than this. But most animals run on four legs. Four legs are better than two, aren't they? Why do we only have two legs?Scientists say that we are more intelligent than other animals because we stand on two legs, so we can use our hands for other things. We can pick things up with them. We can use tools. Human beings have used tools for millions of years. That is why our brains have developed. That is why we have become the most intelligent animals in the world.In the past few years, we have made all kinds of machines. We have made cars, ships, aeroplanes and spacecraft. In these machines we can travel faster than any animal--by land, by sea, or by air. We can even go to the moon. No other animal has ever done that!(Length: 1 min. 30 sec.)A. Answer the following questions.1) What is the fastest animal on land?Key: The cheetah.2) What is the speed of the fastest birds?Key: 170 km/h.3) What is the speed of the fastest fish?Key: More than 100km/h.4) Why can many animals ran faster than human beings?Key: Because most animals run on four legs.5) Why can human beings travel faster than any animals?Key: Because we have machines.B. Decide whether the statements are true (T) or false (F) according to the tape.1) The fastest man in the world can run at 100 km/h. [ F ]2) Most animals run on two legs.

It's really interesting.B: Oh, yeah? Hey, have you learned why the dinosaurs disappeared?A: Well, no one knows for sure.B: I thought it had something to do with the climate. The temperature might have gotten cooler and killed them off.A: Yeah, that's one theory. Another idea is that they may have run out of food.B: Uh-huh. And you know, there's even a theory that they could have been destroyed by aliens from outer space.A: That sounds crazy to me!(Length: 48 sec.)A. Answer the following questions.1) What are the possible reasons why the dinosaurs disappeared?Key: Climate, lack of food and aliens from outer space might be responsible for their extinction.2) Does the man believe in the theory of alien invasion?Key: No.B. Fill in the missing words with what your hear on the tape.B: I thought it had something to do with the climate. The temperature might have gotten cooler and killed them off.A: Yeah, that's one theory. Another idea is that they may have run out of food. B: Uh-huh. And you know, there's even a theory that they could have been destroyed by aliens from outer space.To do the first exercise well, students may be encouraged to take notes while listening. Get them to pay attention to such expressions as "it had something to do with...", "another idea..." and "there's even a theory that..."After doing the exercises, do some oral work on this topic if desired. Question like "Why do you think dinosaurs disappeared?" can be asked.For the shortest life, the first prize must go to the mayfly, which typically lives only a matter of a few hours after it emerges from its shell. Few mayflies live to see the sun rise again. These creatures devote their whole lives to a single desperate mission: finding a mate and producing young. They don't even have functional mouths and stomachs. They simply have no time toeat. In fact they have no time for anything else. The record-holder for the longest life may be the Arctic clam, one of which lived quietly underwater for 220 years. However it did not have any birth certificate to prove this. One could only judge by its growth rings.If you insist on better documentation, the oldest animal ever was probably a tortoise that died in 1918. It had been captured already full-grown in 1766, nine years before the American Revolution began, and it died 152 years later as World War I came to a close.(Length: 1 min. 20 sec.)Answer the following questions.1) What animal has the shortest life? For how long?Key: The mayfly. A few hours.2) What do mayflies do in their lifetime?Key: They just do two things: finding a mate and producing young3) How do we know that one of the Arctic clams lived for 220 years?Key: We could judge by its growth rings.4) How long was the tortoise that died in 1918 kept in captivity?Key: It was kept for 152 years.Every year about 17 million animals are used in laboratory experiments. But in many countries today, a difficult question is being asked: Do we have the right to use animals in this way?People who are for using animals in research argue that theuse of animals in medical research has many practical benefits. Animal research has enabled researchers to develop treatments for many diseases, such as heart disease and depression. It would not have been possible to develop vaccines for diseases like smallpox and polio without animal research. Every drug anyone takes today wastried first on animals.Future medical research is dependent on the use of animals. Which is more important: the life of a rat or that of a three-year-old child? Medical research is also an excellent way of using unwanted animals. Last year, over 12 million animals had to be killed in animal shelters because no one wanted them as pets.However those who are against it point out that the fact that humans benefit cannot be used to justify using animals in research any more than it can be used to justify experimenting on other humans. Animals suffer a lot during these experiments. They are forced to live in small cages, and they may be unable to move.Much of the research that is carried out is unnecessary anyway. Animals have the same rights as humans do--to be able to move freely and not to have pain or fear forced on them. Researchers must find other ways of doing their research, using cell culture and computer modeling. There should be no animals in research laboratories at all.(Length: 1 min. 50 sec.)Key:A. Answer the following question.What is the main idea of the passage?Key: People have different opinions on using animals for research.B. Complete the following ontline of the passage.1) The case for using animals in research:a) Every drug anyone takes today was tried first on animals.b) Future medical research is dependent on the use of animals.c) Medical research is also a good way of using unwanted animals.2) The case against using animals in research:a) Animals suffer a lot during the experiments.b) Much of the research is unnecessary.c) Animals have the same rights as humans do.3) Some alternative ways for scientists to do their research:a) Using cell culture.b) Using computer modeling.Exercise B is designed to help the students get an outline of the passage, and to help them understand both the main idea and the supporting details. It is recommended that the students first take notes without referring to the outline given in the textbook and then fill in the missing information based on their notes. If some of the students find it difficult to finish the task, they may read the outline, and fill in the blanks while listening.Visitors to the National Zoo in Washington D.C. can see three new young tigers. The rare babies met the public for the first time late lastmonth. Chip O'Neal tells us about them.The mother tiger sat nearby on the grass as her babies rolled, chased and bit each other playfully. Then Korenchy also jumped into the games. Her cubs were born at the zoo four months ago. They are called Mike, Eric and Chrisy. The new young tigers at the National Zoo each weigh about 13 kilograms. The fur is dark orange with black stripes. They eat horse meat and drink milk from Korenchy.Korenchy and her babies are Sumatran tigers. Sumatran tigers came from the Indonesian island of Sumatra. They are now in danger of disappearing from the earth. Fewer than 500 of these tigers remain in the world. That includes about 60 living in zoos in North America.Korenchy came to the National Zoo from the Jakarta Zoo in Indonesia. The gift was part of the Sumatran Tiger Species Survival Program. Korenchy has given birth to live cubs three times. The father of her new cubs is Rokan, a Sumatran tiger who arrived two years ago from another zoo. Korenchy and Rokan had their babies the natural way instead of the scientific method often used to produce young animals in zoos.A wire fence separates Rokan from his babies. Zoo workers who care for Rokan say he reaches through the fence to wash the cubs with his tongue. They say this means he recognizes Mike, Eric and Chrisy as his cubs. However, zoo officials are hoping that Rokan will produce more cubs with another female Sumatran tiger at the zoo, so they do not want him to become too interested in this family.The National Zoo hopes to keep the Sumatran tiger cubs for at least 18 months before sending them to other zoos. That is about the age when most tiger cubs in the wild leave theirmothers. The National Zoo has placed cameras in the Sumatran tigers' living area, so people with computers can see them. To do this, use your computer to find the National Zoo's Website at /natzoo.(Length: 3 min. 40 sec.)Key:A. Answer the following questions.1) Was the mother tiger born in the National Zoo as well?Key: No.2) Why is the father tiger separated from his cubs?Key: Because zoo officials want him to produce cubs with another female tiger, so they don't want him to become too interested in this family.B. Complete the following sentences with what you hear on the tape.1) The young tigers are four months old.2) Each of them weighs about 13 kilograms.3) They eat horse meat and drink their mother's milk.4) People with computers can see the daily life of these tigers by visiting theNational Zoo's Website at /natzoo.C. Choose the best answer to each of the following questions.1) How many Sumatran tigers remain in the world? ( C)a) About 60. b) More than 500. c) Less than 500.2) Korenchy has given birth to ( C)a) three cubs b) four cubs c) five or more cubs3) After 18 months, these cubs will be sent ( b)a) to the wild b) to other zoos c) to the Jakarta ZooCats in AmericaAn old expression says, "Man's best friend is his dog." Today, however, it seems that cats have replaced dogs as the most popular pets in American homes.Americans have more than 62 million pet dogs. But even more cats--more than 64 million-- live in American homes.These pet cats may have long hair or short hair. They are different colors and sizes. Some are costly animals that take part in competitions. Many more are common American mixtures of several kinds of cats.Most house cats live a good life. They are not expected to work for their food. Instead, they rule their homes like furry kings and queens. They wait for their owners to serve them.Americans are increasingly serious about their cats. These concerns have made the care of cats into big business.Each year, cat owners buy tons of food especially prepared for cats. They buy toys and other equipment. They buy jewelry and clothes for themselves with images of cats on them. Some owners even bury their dead pets in special burial grounds.Humans have loved and respected cats for centuries. Scientists have evidence that cats and people lived together as long as 8,000 years ago. The small house cat was once a highly honored animal. In ancient Egypt for example, people who killed a cat could be punished by death.Early in American history cats were not treated as gods,however. They probably arrived in the United States with settlers and traders from Europe. These cats worked. They killed rats and mice.Sometimes, Americans mistreated their cats. During the early days of the nation, religious extremists believed that some cats were working for the devil. Black cats were especially suspected of being evil.Later, American families who had enough food began taking cats into their homes. People cared for the cats because the animals gave them pleasure. The cats thanked people for feeding them by making a purringsound. This pleasant noise usually means a cat is happy.Animal experts offer several reasons why cats have become so popular as house pets. They say cats need less care than dogs. And cats do not seem to suffer as much as dogs from being alone if the owners are away. Still, millions of other people do not like cats at all. They say dogs are better and more loving pets. They say cats do not have much feeling. They believe cats stay with people only to be fed. Cat owners defend their pets against such criticism. They say cats are just much more independent than dogs.A student of animal medicine explains the situation this way: dogs follow you around—they want you to talk to them and play with them a lot of the time. Cats like more space and more privacy----does not mean they do not love their owners.(Lenght: 4 min. 27 sec.)A. Answer the following questions.1) Which have become more popular in America, dogs or cats? How do you know that? Key: Cats have become morepopular, because there are more pet cats in American homes.2) How long have humans had cats in their homes?Key: About 8,000 years.3) Where did American house cats come from?Key: They probably arrived in the United States from Europe.4) Cats have been treated well in the United States all along, haven't they?

Fill in the missing words in the summary.1) The care of cats has become a big business, because cat owners:a) buy tons of food especially prepared for cats.b) buy toys and other equipment.c) buy things with images of cats on them.d) bury their dead pets in special burial grounds.2) People who prefer cats say cats:a) give their owners pleasure.b) need less care.c) suffer less from being alone.d) are more independent.C. Decide whether the statements are true (T) or false (F) accord-in9 to the tape.1) Most house cats lived a good life. [ F ]2) Early American cats were treated like gods. [ F ]3) Black cats were once suspected working for the devil. [ T ]4) Cats are treated like fairy kings and queens. [ F ]5) Cats want you to talk to them a lot. [ F ]All the exercises for this passage are designed to help the students get details. In Exercise C, sentence 4) may cause someproblem. For some students the word "furry" may sound similar to "fairy". Make the students aware that in listening comprehension context is very important too. "Cats are treated like fairy kings and queens" simply doesn't make sense, therefore it's false.Little Steve has a pet rabbit, Bunny. He plays with it every day after school. One day his mother sees that her little boy is holding Bunny by the ears. From time to time he gives the poor rabbit an angry shake and says, "How much is two plus two? Steve," says his mother, "why do you treat your poor little Bunny that way?""Well," explains Steve angrily, "our teacher says that rabbits multiply very quickly, but this dummy can't even add."(Length: 40 sec.)This is a humorous story. First do the dictation. Then call the students' attention to the word "multiply" which can mean "produce large numbers of offspring" or "add a number to itself a particular number of times". The boy misunderstood, hence the humour.Script:Most mammals live on land, but not all of them. Millions of years ago, some mammals went back to the sea and lived there.The legs of these animals disappeared, and after a long time they looked like fish. These animals became whales and dolphins.Whales and dolphins are still like other mammals in many ways. They are warm-blooded and they breathe air. They also have big brains. That is why they are more intelligent than fish. Whales have the biggest brains in the world. Their brain is bigger than the brain of a human being.(Length: 50 sec.)Objectives:0 Understand what animals are being described.Get to know more about animals.Get to know more about how man and animals co-exist.Catch main ideas and supporting details.0 Have practice in liaison and contraction.1) They live in Africa and India. They have four legs and a tail. They are very big and very strong. They are intelligent, too. They have a trunk (树干;躯干;象鼻)and some of them have tusks (獠牙).They sometimes live for 70 years.2) They live in Africa and Asia. They are brown. They have arms and legs, but they don't have a tail. Their arms are very long and they have big ears. They are good climbers. They are very intelligent, too.3) They live in Africa. They are very tall. They have four legs,a tail and a very long neck. They eat leaves and twigs(小枝;嫩枝). They can run very fast. They are brown and white.4) They live in very cold countries. They have wings, but they can't fly. They are good swimmers. They eat fish. They are blue and white or black and white.5) They live in Australia. They are red or gray. They have short from legs, long back legs and a very long tail. The back legs and the tail are very strong.

Complete the following sentences with what you hear on the tape.1) They live in Africa and India. They have four legs and a tail.2) Their arms are very long and they have big ears.TipsIn case the students don't know some of the English names for these animals, they may give the names in Chinese. And then get them practise saying them in English. Alternatively, you could elicit/ introduce such animal names as chimpanzee, penguin, zebra and kangaroo.The fastest animal on land is the cheetah([ 't?i:t? ]猎豹). It can run ata speed of about 100 kilometres an hour. The fastest bird in the world can fly at 170 km/h(尖尾雨燕), and the fastest fish can swim at more than 100 km/h(旗鱼).Human beings are not very fast. The fastest man in the world can only run at about 40 km/h. Many animals can run faster than this. But most animals run on four legs. Four legs are better than two, aren't they? Why do we only have two legs?Scientists say that we are more intelligent than other animals because we stand on two legs, so we can use our hands for other things. We can pick things up with them. We can use tools. Human beings have used tools for millions of years. That is why our brains have developed. That is why we have become the most intelligent animals in the world.In the past few years, we have made all kinds of machines. We have made cars, ships, aeroplanes and spacecraft. In these machines we can travel faster than any animal--by land, by sea, or by air. We can even go to the moon. No other animal has ever done that!(Length: 1 min. 30 sec.)A. Answer the following questions.1) What is the fastest animal on land?Key: The cheetah.2) What is the speed of the fastest birds?Key: 170 km/h.3) What is the speed of the fastest fish?Key: More than 100km/h.4) Why can many animals ran faster than human beings?Key: Because most animals run on four legs.5) Why can human beings travel faster than any animals?Key: Because we have machines.B. Decide whether the statements are true (T) or false (F) according to the tape.1) The fastest man in the world can run at 100 km/h. [ F ]2) Most animals run on two legs.

It's really interesting.B: Oh, yeah? Hey, have you learned why the dinosaurs disappeared?A: Well, no one knows for sure(确实;毫无疑问地).B: I thought it had something to do with(这与…有关)the climate. The temperature might have gotten cooler(冷的)and kill ed them off(消灭,杀光). A: Yeah, that's one theory. Another idea is that they may have run out of(用完,耗尽)food.B: Uh-huh. And you know, there's even a theory that theycould have been destroyed by aliens(外星人)from outer space.A: That sounds crazy to me!(Length: 48 sec.)A. Answer the following questions.1) What are the possible reasons why the dinosaurs disappeared?Key: Climate, lack of food and aliens from outer space might be responsible for their extinction.2) Does the man believe in the theory of alien invasion?Key: No.B. Fill in the missing words with what your hear on the tape.B: I thought it had something to do with the climate. The temperature might have gotten cooler and killed them off.A: Yeah, that's one theory. Another idea is that they may have run out of food. B: Uh-huh. And you know, there's even a theory that they could have been destroyed by aliens from outer space.To do the first exercise well, students may be encouraged to take notes while listening. Get them to pay attention to such expressions as "it had something todo with...", "another idea..." and "there's even a theory that..."After doing the exercises, do some oral work on this topic if desired. Question like "Why do you think dinosaurs disappeared?" can be asked.For the shortest life, the first prize(一等奖;第一名)must go to the mayfly(蜉蝣), which typically(代表性地,典型地)lives only a matter of(大约,左右)a few hours after it emerges from its shell. Few(很少;几乎没有)mayflies live to see the sun rise again. These creatures devote their whole lives to a single desperate(令人绝望的)mission: finding a mate(配偶)and producing young. They don't even have functional(功能的)mouths and stomachs. They simply have no time to eat. In fact they have no time for anything else.The record-holder(记录保持者)for the longest life may be the Arctic clam(蛤蜊), one of which lived quietly underwater for 220 years. However it did not have any birth certificate(出生证明)to prove this. One could only judge by its growth rings(生长轮,年轮).If you insist on better documentation(文件材料), the oldest animal ever was probably a tortoise that died in 1918. It had been captured(捕获)already full-grown(发育完全的,长足的)in 1766, nine years before the American Revolution(美国独立战争)began, and it died 152 years later as World War I came to a close.(Length: 1 min. 20 sec.)鹤寿千岁,以极其游;蜉蝣朝生而暮死,而尽其乐(仙鹤的千年寿命,用来尽情遨游;蜉蝣早上出生,傍晚就死了,但也的到它的快乐) ---淮南王刘安寄蜉蝣于天地,渺沧海于一粟。

Research on the Development and Practice of High School STEM School-based Curriculum Based on Innovative EducationYuming XiaTongliang Middle SchoolAbstract: The current high school education to develop students ability to innovate as the center, with STEM-based curriculum to supplement the textbook, is an important way to promote the overall development of students. Combining the two can improve the teaching effect of high school curriculum and help to innovate students’ understanding of knowledge in school curriculum. STEM-based curriculum development should pay attention to the breadth of knowledge, we introduce the status quo of middle school STEM-based curriculum, teaching strategies and to develop and practice basis points lower secondary education curriculum knowledge framework of educational innovation are described. Keywords: High school; STEM; School-based curriculum; Innovative education DOI: 10.47297/wspiedWSP2516-250021.202105031. IntroductionSTEM is an emerging comprehensive education philosophy, science, technology, mathematics and other multidisciplinary subjects. It can not only expand the application of basic knowledge, but also promote students’ in-depth study and understanding, cultivate students’ comprehensive learning ability, and realize comprehensive quality education. However, the current high school curriculum development and practice still lack innovative suggestions. The format is too single, especially in terms of knowledge, lack of complete content and methods. The participation rate of students in courses is not high, which is why we develop and implement STEM school-based courses on the basis of innovative education, so that middle school students have the ability to cultivate and developAbout the author : Yuming Xia (1986-12), male, Han nationality, native place: Hechuan, Chongqing; Tongliang Middle School, Title: First Class Teacher; research.Fund Project: Chongqing Normal High School Curriculum Innovation Base Project in 2021《Tongliang Middle School Physics Curriculum Innovation Base Project》(Approval Number:Yujiao Jifa [2021] No. 4).131Journal of International Education and Development Vol.5 No.3 2021high school education literacy.2.The Status Quo of High School STEM School-based CurriculumAt present, school-based curriculum development has achieved good results in the high school stage, enabling students to apply basic cultural knowledge to school curricula and broaden their knowledge, but its development is mainly reflected in science and mathematics, and almost all of them are technical of. There are certain shortcomings in teaching. With the development of education reform, teaching can be combined with university compulsory courses to participate in project organization and practice, promote the concept of knowledge application through the process, and promote the connection between knowledge and core knowledge. High school and high school education teachers should pay attention to school-based Curriculum development and practical teaching ensure the teaching effect, so that students can learn comprehensively, think comprehensively, and grow in an all-round way.For example, Clark and Ernest published a case model integrating science, technology, and mathematics in 2007, reflecting the integration of biology courses and STEM courses, and providing a theoretical basis for stem cell integration; Heschbach advocated stem cell teaching in 2011, and From the perspective of the convergence of STEM school-based courses and comprehensive courses, the science, technology, and mathematics courses have been reorganized: limitations and challenges. Margaret et al. published “Using Stem Cell Quality Framework to Build a Bridge Between Engineering and PK-12 Curriculum”, which discussed As for the impact of related projects on students’ interests, foreign researchers have also begun to shift from simple theoretical research to integrated research on curriculum research. By designing stem cell projects, combining science and technology, mathematics and other disciplines with students’ learning interests, improve students’ practical ability and promote students’ all-round development.3. Research Results(1) Read the literature and organize it into a bookThe researchers investigated STEM school-based courses in various countries and proposed seven core qualities of stem cell students: critical thinking, information collection and integration, communication and cooperation, creative problem solving, lifelong learning, self-confidence and adjustment, and growth thinking.132133(2) Compile 2 copies of the school textbookIn view of the current status of college students and literature research, researchers have developed two school-based textbooks, namely the design and production of monochromatic courseware, such as the design and production of the structure chain of tea polyphenols (Based on cultivating the seven core qualities of students, pay attention to infiltrating vocational education and cultivating students’ artistic appreciation ability).(3) Orderly classroom teachingThe classroom teaching mode of “problem-oriented” and “group cooperation” is adopted, and students have a high degree of participation. Foreign teaching and learning in the classroom is based on the family, and practical teaching is carried out. For example, in a high school, the STEM course designed is to visit the Diaoyu City, on this basis, to understand the historical and cultural heritage of the Diaoyu City, or to design and manufacture stone throwing machines under the guidance of parents. Carry out the classroom teaching of “Catapult design and production” in such as; in the autumn of 2017, carry out the classroom teaching of “Teaphenol chain belt design and production”(4) Popularize STEM education throughout the schoolDuring the 2016 winter vacation, the school carried out stem cell innovation training, popularized stem cell education throughout the school, improved students’ ability to solve problems, adapted to various learning activities in a flexible future learning space, and inspired students to create in non-teacher classrooms Strength, promote cooperative learning, exploration and experimental learning.(5) The micro-channel by universalizationAt the beginning, the researchers set up a chat group in which the researchers can mobilize the attention of parents while sharing their tribal military knowledge with the children. The acquisition of knowledge, teamwork and innovative learning have penetrated. Under the influence of researchers, many parents have begun to attach importance to training and agree with the concept of learning across disciplines and projects.4. High School and High School Education STEM School-based Curriculum Development and Innovative EducationCurriculum development and discipline integration based on stem cells will realize innovative education based on STEM. However, lack of knowledge of science and technology for high school students, it is difficult to stop learning. Therefore, in curriculum development, it is necessary to strengthen the introductionResearch on the Development and Practice of High School STEM School-based Curriculum Based on Innovative EducationJournal of International Education and Development Vol.5 No.3 2021of high school education science and engineering knowledge, so that students have a certain understanding of the curriculum, and can develop curriculum content on the basis of projects, so that students can participate in innovative learning and understanding, and can Participate in school subsidy courses.(1) Contents of popularization of high school education technologyIn the high school stage, basic knowledge education knowledge is a basic concept. In this subject, students have more knowledge, fewer changes and ideas. Therefore, in the development of STEM school-based curriculum, it is necessary to popularize the content of high school education technology, so that students can fully understand high school education technology, understand the research status of high school education technology in society, and enable science and technology to be implemented. Examples of genetic research, seed production, high school education materials, ecological environment, pathology research, and other high school education science and technology. The teaching content ensures that students have a comprehensive understanding of knowledge points, improves students’ learning and comprehension abilities, creates a basic environment for comprehensive STEM education, and at the same time realizes enlightening education, enriches school curriculum content, and ensures students’ understanding and interest in learning At the same time, there is a practical innovation education process.(2) The combination of engineering and knowledge pointsThe engineering content of school-based courses requires the development of teaching materials, the construction of environment and technical content, and the integration of high school education engineering. For example, urban engineering design should ensure the ecological environment of the city, consider environmental protection and high school education research in space technology in transportation; help students understand high school education technology and apply it to school curricula. When innovation training, to focus on questionnaires and practical, and appropriate to reduce the content standards, the development of practical approach, innovation in the classroom so that students apply knowledge knowledge, deepen understanding.(3) School-based curriculum development projectBased on STEM courses and developing courses in the context of innovative training, the teaching methods should be emphasized, and the teaching of knowledge points should be combined with school courses to achieve innovative training and improve the teaching effect of knowledge points. In terms of method, use project thinking, use stem cell thinking, and use project content to enable students to carry out project design and project teaching based on the presentation and application of curriculum knowledge such as science, technology, technology,134135and mathematics. It is necessary to have a scientific understanding of high school education knowledge, to analyze from the technical level, to use technology, mathematics and other knowledge to ensure good teaching results, and to innovate in practice.5. The Practice of STEM School-based Curriculum in High School and High School Education under the Background of Innovative EducationIn practice, we should focus on student performance in the school curriculum, good counseling innovation, seize the personality development of students, training of comprehensive thinking awareness, improve creativity.(1) On the basis of teaching material on the rational implementation of school-based curriculumIt is necessary to develop synchronously with the teaching materials, distinguish the primary and secondary relationships, and avoid homogeneity. It is necessary to continuously innovate in the process of writing teaching materials, promote the application of theoretical knowledge through project design, and strengthen the rational development of applied courses. This is not only comprehensive training. The foundation of comprehensive learning is also a necessary condition for the implementation of comprehensive learning.(2) Use school-based curriculum for research in classCombining the curriculum practice based on school education with the supplement of classroom teaching knowledge points can improve the classroom teaching effect. Oriented by applied research, organize students to carry out high school education applied research in the fields of science, technology, mathematics, etc., to promote thinking analysis, improve the level of cognition, so that students can acquire a wealth of knowledge and cultivate basic knowledge.(3) Analyze the results of project learningBased on the teaching of STEM courses, the analysis of research learning results should be emphasized in practice. This is a new teaching mode, it is a new method, new method, new method, new method of applying network technology to teaching, it is a teaching mode based on the network environment, it is a kind of teaching mode based on the network environment Teaching mode under.Research on the Development and Practice of High School STEM School-based Curriculum Based on Innovative EducationJournal of International Education and Development Vol.5 No.3 20216. Concluding RemarksAll in all, the curriculum based on school education has become an important means of quality education and teaching. In development and practice, students’ learning should be put first. It is necessary to use teaching materials as the basis to enrich students’ understanding of school courses, broaden students’ basic knowledge, and conduct practical teaching according to students’ ideas. However, in development and practice, it is necessary to adhere to student-oriented learning strategies and reduce rote memorization. Improve the teaching level and ensure the effective implementation of school-based courses.References[1] XU Songfeng. “Research on the Development and Innovation of School-basedPhysical Education Curriculum in Colleges and Universities” [J].

Governments and industries around the world are investing in renewable energy sources such as solar and wind power. These sources of energy are abundant and can be harnessed without causing significant harm to the environment.Solar power is obtained from the sun’s rays and can be converted into electricity or used directly for heating and lighting purposes. It is considered one of the most promising forms of renewable energy due to its availability and low environmental impact.Another source of renewable energy is wind power, which is generated by the wind’s kinetic energy. Wind turbines can convert this energy into electricity, which can then be used to power homes, businesses, and even entire cities. Wind power is particularly effective in areas with strong and consistent winds.In addition to solar and wind power, other forms of sustainable energy include hydropower, biomass, and geothermal energy. Hydropower harnesses the energy of flowing or falling water to generate electricity, while biomass uses organic matter such as wood or agriculturalwaste to produce energy. Geothermal energy utilizes the heat from the Earth’s core to generate po wer.As the world continues to search for cleaner and more sustainable energy sources, the future of renewable energy looks promising. With advancements in technology and increased investment in research and development, we can expect to see even greater utilization of renewable energy in the near future.2.

True, GM foods are already very much a part of our lives (已成为我们 生活的一部分), and farmers have a strong incentive to (迫切地想要) use the biotechnology as it can raise overall crop productivity (能提高稻谷 产量), yet we need a deep philosophical discussion of its implication. We still remember that when pesticides were first introduced, they also were praised as absolutely safe and as a miracle cure for farmers. But for all that promise (尽管这么多保证), decades later the technology revealed its truer lethal implications. Hence, any technology should be subjected to rigorous testing (应该进行严格的测试) before its wide application.

strategy湖泊是陆地表层系统各要素相互作用的节点,是地球上重要的淡水资源库、洪水调蓄库和物种基因库,与人类生产与生活息息相关,在维系流域生态平衡、满足生产生活用水、减轻洪涝灾害和提供丰富水产品等方面发挥着不可替代的作用.中国幅员辽阔,湖泊数量多、类型全、分布广、变化复杂,据5中国湖泊志6记载,全国共有面积大于1.0km2的湖泊2759个,总面积91019.6k m2[1],广泛分布于东部平原、青藏高原、云贵高原、蒙新高原、东北平原与山地等五大湖区.近几十年来,随着区域气候环境变化和人类活动干扰加剧,不仅湖泊数量、形态和分布发生了巨大变化,而且湖泊水量、水质和水生生物种群与数量变化也十分显著.生态系统退化、水体富营养化、洪水调蓄能力降低和受人类活动干扰强烈等成为中国湖泊普遍面临的重大问题,严重影响流域经济社会可持续发展和居民生活安定,倍受各级政府和社会各界的广泛关注.为摸清全国湖泊家底,填补我国湖泊科学研究空白,1950s末至1980s中期,我国开展了第一次全国湖*科技部国家科技基础性工作专项/中国湖泊水质、水量和生物资源调查0(2006F

*不包括干盐湖.杨桂山等:中国湖泊现状及面临的重大问题与保护策略801从空间分布来看,拥有面积1k m2以上湖泊数量最多和面积最大的是青藏高原湖区,湖泊数量1055个,面积41831.7k m2,分别占全国湖泊总数量和总面积的39.2%和51.4%;其次是东部平原湖区,湖泊数量634个,面积21053.1k m2,分别占全国湖泊总数量和总面积的23.5%和25.9%;再次是蒙新高原湖区,湖泊数量514个,面积12589.9k m2,分别占全国湖泊总数量和总面积的19.1%和15.4%;第四是东北平原与山地湖区,湖泊数量425个,面积4699.7k m2,分别占全国湖泊总数量和总面积的15.8%和5.8%;最少的是云贵高原湖区,湖泊数量65个,面积1240.3k m2,分别仅占全国湖泊总数量和总面积的2.4%和1.5%.其中,东部平原、云贵高原、东北平原与山地三大湖区属外流区,属亚洲季风湿润气候,湖泊大多为开放的淡水湖;青藏高原湖区和蒙新高原湖区基本属于内流区,属干旱半干旱气候,湖泊大多为封闭的咸水湖或盐湖.与历史湖泊调查数据[1]相比,近30年来,全国新生面积在1.0km2以上的湖泊60个,主要位于冰川末梢、山间洼地、河谷湿地,集中在青藏高原和蒙新高原湖区;消失面积在1.0k m2以上的湖泊243个,主要分布在蒙新高原湖区和东部平原湖区的长江中下游地区,其中10.0km2以下的湖泊147个,10.0-100.0km2的48个,100.0-500.0k m2的4个(新疆的曲曲克苏湖、青格力克湖、加依多拜湖和乌尊布拉克湖),1000.0k m2以上的1个(新疆的罗布泊).因围垦而消失湖泊102个,约占消失湖泊总量的42.0%,均分布在东部平原湖区,自然和人为影响干涸的湖泊97个,约占消失湖泊总量的40%,主要分布在蒙新高原湖区.2中国湖泊面临的重大问题2.1湖泊围垦导致水量调蓄能力下降,加重流域洪水灾害湖泊是淡水资源的重要储存器和调节器,在流域水资源供给和洪水调蓄方面发挥着不可替代的作用,尤其是在我国东部平原区,湖泊承担的供水和防洪功能在保障流域居民安居乐业方面的地位更是举足轻重.然而,近几十年来,受人多地少和对湖泊功能认识不足等因素影响,导致湖泊被大量不合理围垦,造成湖泊面积急剧减少.据不完全统计,1940s末以来,长江大通以上中下游地区有1/3以上的湖泊面积被围垦,围垦总面积超过13000k m2,这一数字约相当于目前五大淡水湖面积总和的1.3倍,因围垦而消亡的湖泊达1000余个[6](图1).太湖流域已建圩湖泊达498个,受围垦的湖泊239个,减少湖泊面积约529k m2;因围垦而消亡湖泊165个,占该区原有湖泊数量的23.3%[7].大通水文站以上长江中游地区的湖泊面积由1950s 初的17198k m2,减少到现不足6600k m2,约2/3的湖泊因围垦而消失,其中,洞庭湖因围垦,湖泊面积已由建国初期的4350k m2急剧缩小至2625k m2;鄱阳湖面积也由1949年的5200km2减少到目前的2933k m2.号称/千湖之省0的湖北省,在1950s末计有湖泊1066个,至1980s初剩约309个,目前面积大于1k m2湖泊仅剩181个,大于10k m2的湖泊仅剩44个(不包括长江干流人工改道形成的水域)[8].图1长江中游地区1949年以来湖泊面积变化F i g.1A rea changes o f the l akes i n t he m i ddle reaches o f Y angtze R iver si nce1949大规模围垦不仅使湖泊面积锐减,同时也使湖泊蓄水容积大幅减少.初步调查表明,1950s初以来,长江中下游地区因围垦减少湖泊容积超过500@108m3,相当于淮河多年平均年径流量的1.1倍,五大淡水湖泊蓄水总量的1.3倍[8].k e Sci.(湖泊科学),2010,22(6)湖泊调蓄容积的减少,直接导致湖泊洪水调蓄功能下降,在相当程度上引发了江湖洪水位的不断升高,最高洪水位被不断突破.如太湖最高洪水位1954年为4.65m,1991年为4.79m,1999年抬高至5.07m[9].鄱阳湖多年平均最高洪水位1950s为18.51m,1970s为18.93m,1990s跃升至20.10m,达到或超过警戒水位19m的出现频率,1950s为35%,1980s为40.6%,1990s更进一步上升至55%[10].洞庭湖区1998年,湖口城陵矶站最高洪水位分别比1954年、1996年高出1.39m和0.63m,达到历史最高记录.1998年仅湖南、湖北和江西三省的直接经济损失就达1090@108元,其中湖南省329@108元,湖北省384@108元,江西省377@108元,洪涝灾害危害程度不断加大[11].2.2入湖污染物大量增加,湖泊水环境质量不断下降随着湖泊流域和周边地区人口增长和经济快速发展,导致进入湖泊TN,TP和COD M n等污染物增加,湖泊水环境污染不断加重,尤其是在我国东部平原湖区,入湖污染物增加引起湖泊水环境质量急剧下降.根据2001-2002水文年115条环太湖河道同步水文监测资料与1987-1988水文年资料对比,入湖污染物除TP略有减少外,COD M n,TN等主要污染物均明显增加,COD M n由32350t/a增加到37579t/a;TN由20241t/a增加到-N由5363t/a增加到12432t/a[12];另据江苏省水文水资源勘测局监测,2007年江苏省环太湖28658t/a;NH+4TP,TN和NH+4-N入湖量分别达1862,t35100t和18300t[13].入湖污染物量的持续增加导致太湖营养盐(TN、TP)浓度不断升高[14],水质不断下降.据调查,1980s前期太湖仍以Ò至Ó类水为主,处于尚清洁状态,后期以Ó类水为主,呈现一定的污染趋势;到1990s中期以Ó至Ô类水为主,属轻度污染,局部Õ类水;后期以Ô至Õ类水为主,局部已劣于Õ类水;2000年后,全太湖水体以Õ类水为主,属重污染,其中太湖西岸地区、梅梁湾、竺山湾水质较差,已劣于Õ类水[14-16].2007年梅梁湾藻类水华大规模爆发及污水团事件,引起了国家和全社会对太湖水环境的高度重视[17].受入湖污染物快速增加的影响,鄱阳湖水质总体也呈下降趋势.1980s鄱阳湖水质以Ñ、Ò类为主,Ñ、Ò类水体平均占比达85%以上,Ó类水体占比不足15%;至1990s,Ñ、Ò类水体占比平均下降到70%,Ó类水体平均占30%;进入21世纪,特别是2003年以来,Ñ、Ò类水体平均只占50%,Ó类水体平均占32%,并出现18%左右的劣Ó类水体,主要超标项目为TN、TP[18].近几年以来,鄱阳湖TN、TP污染水平虽总体较太湖、巢湖等湖泊轻,但已有部分湖区(如莲湖、康山断面)的TN浓度接近巢湖2007年平均水平,TP浓度接近太湖2007年平均水平,如2006年,鄱阳湖全湖平均TN与TP浓度分别高达1.59mg/L和0.073mg/L(图3).图2太湖1990-2007年水体TN、TP浓度变化(据文献[14])F

ng1980-2009杨桂山等:中国湖泊现状及面临的重大问题与保护策略803云贵高原湖区湖泊水环境质量下降趋势也十分明显,2008年调查数据与历史[1]相比,1998-2008年20年间,滇池TN和TP浓度分别升高75%和78%,分别达2.57m g/L和0.193m g/L;星云湖TN和TP浓度分别升高了1.6倍和3.5倍,其他湖泊TN、TP浓度也有不同程度增加.由于营养盐含量的增加,浮游藻类数量明显增多,导致水体透明度下降;云贵高原13个湖泊中,抚仙湖、星云湖、阳宗海、异龙湖、洱海、程海和邛海透明度下降显著,下降幅度从40%到70%,其中程海最为明显,透明度下降了70%.湖泊水体TN、TP等污染物浓度增加,导致湖泊水体富营养化不断加重,据2007-2010年对东部平原湖区、东北平原与山地湖区和云贵高原湖区138个面积大于10k m2湖泊水质调查,采用TN、TP、Ch.l a、SD、SS 和COD M n6个水化学指标进行评价的湖泊营养指数(TSI)显示,138个湖泊中有85.4%的湖泊超过了富营养化标准,其中达到重富营养化标准的占40.1%,而全湖全年均为贫营养水平的仅泸沽湖一个,部分湖泊在部分湖区(部分季节)存在贫营养状态,但全湖平均也大都为中营养水平,如云南抚仙湖、江西军山湖等,中营养和贫营养湖泊总计仅为14.6%.其中,东北平原与山地湖区湖泊富营养化比例最高,达96.0%,其次是东部平原湖区的长江中下游地区,为85.9%,云贵高原湖区最低,为61.5%(图4).我国五大淡水湖(鄱阳湖、洞庭湖、太湖、洪泽湖和巢湖),其水环境质量都不容乐观,除洞庭湖目前尚处于中营养水平外,其余四大淡水湖,整体上已经处于富营养化水平(图4a).2.3湖泊生物资源退化,生物多样性下降近几十年来,我国湖泊生态总体处于不断退化状态,集中表现为鱼类资源种类减少、数量大幅下降,生物多样性不断降低,高等水生维管束植物与底栖生物分布范围缩小,而浮游植物(藻类)等大量繁殖并不断集聚形成生态灾害.在我国东部平原湖区,湖泊生态退化的最主要原因是人类活动引起的湖泊水质下降和水体过度利用等,其中湖泊过度围网和围堤养殖活动是重要方面之一,尤其是长江中游地区湖泊,如长湖、大冶湖、斧头湖等中小型湖泊以及一些大型湖泊湖湾,几乎全湖被围网割裂.东太湖,1990年网围养殖范围仅占湖泊水面的9.5%左右,至2003年养殖水面已超过湖泊水面的81.2%[18].不合理湖泊过度养殖,大量消耗水生植物,造成湖泊湿地水生植被的消失,而且为了获取最大的经济效益,普遍向湖泊投放过量鱼类饵料,有的甚至直接向湖中投放化肥,加剧湖泊富营养化程度的同时,也直接造成湖泊生态系统破坏.据调查数据对比分析[7],作为我国第三大淡水湖的太湖,鱼类资源种类由1960s的106种下降到目前60-70种,洄游性鱼类几乎绝迹;底栖动物中螺、蚌等大型软体动物减少,耐污染水蚯蚓、水生昆虫幼体增加;浮游动物中大型的枝角类、桡足类种群、数量减少,而小型的轮虫、原生动物数量大幅增加;水生高等植物分布范围大幅度缩减,1960s 以来分布面积减少了126k m2,而且群落组成趋于简单,沿湖岸大型挺水植物几近消失.我国第二大淡水湖洞庭湖,1950s捕捞的经济鱼类有100多种,产量达到4@104,t到1990s能捕捞到的天然鱼类降低为70种,天然捕捞量降低到不足1.3@104t[19].随着富营养化的日益加剧,云贵高原湖泊的生物多样性也受到重大影响,生物组成结构发生了很大变化,高等水生植物种类减少,其中敏感种消失,耐污种数量增多,水生生物种类、群落类型及分布区域与历史资料相比下降显著.沉水植物种类减少,分布范围缩小,例如滇池,1950s沉水植物有42种,1980s下降到13种,1990s有12种[20],本次调查只有8种.水生浮游藻类种类减少,但是生物量快速增加,许多湖泊蓝藻的优势度已经超过90%,其中滇池、星云湖和杞麓湖都出现大面积蓝藻水华.鱼类结构也发生很大变化,1997年,云南鱼类种数达432种,其中土著鱼类超过400种,占全国淡水鱼类种数的42.2%[21],和历史资料相比[22],各湖泊的土著鱼类种类下降幅度均较大,其中滇池下降幅度最大,达到96.0%,抚仙湖下降幅度最小,也达到60.0%,外来鱼种已经成为各湖泊鱼类资源的主体,滇池原有土著鱼类24种,现在湖区仅有4种,本次调查仅获得1种,其它20种鱼已多年未采到标本,有的种类可能已经消失,有的种类正在消亡之中.我国西部地区湖泊,由于气候变化和人为因素共同作用,导致湖泊水位下降、水体盐碱化、富营养化加重,同样也面临生态退化和渔业资源减少问题.如蒙新高原湖区的呼伦湖,浮游植物种类已由1988年调查的181种属减少到目前的142种属;浮游动物生物量由1998年4.1m g/L下降到目前的1.7m g/L;底栖动物生物量由1988年0.408m g/m2下降到目前的0.339m g/m2,并已经出现耐低盐种k e

m2减少到1980s的1903.9h m2,芦苇从4703.9h m2减少到1437.2h m2,次生胡杨林也减少了30%;博斯腾湖原来具有丰富的芦苇植被资源,1959年航测资料统计,芦苇面积5.58@104h

m2,蕴藏量约265.58@104,t近十多年来,湖泊面积和芦苇产量均呈波动萎缩状态[1].2.4西部地区湖泊总体呈萎缩消亡态势,水量减少、水质持续恶化近几十年来,受气候变化周期性和冰川快速消融等要素的影响,我国西部地区湖泊水量和面积呈现明显的波动变化,不同时段萎缩与扩张交替变化,但总体呈现萎缩态势,不少湖泊甚至干涸消失.青海湖是我国最大的湖泊,近50年来,湖泊水位整体呈下降趋势,其中,1961-2002年间累计水位下降了3.23m[24];1998年水面面积比1989年减少了90k m2[25];2005-2009年,受流域降水增加影响,青海湖水位连续5年回升,面积有所扩大[26].据近30年青藏高原三江源地区24个主要湖泊遥感调查数据分析表明[27],三江源地区主要湖泊近30年大部分经历了从萎缩到扩张的波动变化过程,2004年以前大部分湖泊表现为萎缩,2004年以来表现为缓慢扩张,总体上都以萎缩为主,1975-2006年期间湖泊面积减少了65.8km2,约占三江源地区调查湖泊总面积的3%.调查结果显示,近50年来,我国西部青藏高原和蒙新高原两大湖区消失湖泊数量达126个,消失湖泊面积超过7378.4k m2(表2).如青藏高原湖区米提江占木错,面积约600km2,已解体萎缩成4个串珠状湖泊;乌兰乌拉湖也已分离为5个小湖泊,并发育了多级湖滨阶地;苟仁错在1960s为咸水湖,到1980s 发展成盐湖,面积仍有23.5k m2,现已近干涸;雀莫错近50年来面积减少了近1/2[28].新疆罗布泊,历史最大面积达5200k m2,1931年湖泊面积还有1900k m2,1962年仍然有660k m2,至1970s初则完全消亡,成为广袤的干盐滩.位于吐鲁番盆地的艾丁湖,1950s湖泊面积有124k m2,至1980s中后期只有5k m2,1990s中期则完全干涸.玛纳斯湖,1957年湖泊面积约550k m2,至1960s后期干涸.内蒙古居延海,主要依靠祁连山区的降水和冰雪融水补给,湖泊面积最盛时曾达2600k m2,至1958年,东、西居延海有面积302k m2,湖泊蓄水量6.1@ 108m3,后由于入湖河流断流现象日趋严重,无水量补给,导致东、西居延海分别于1963年和1961年相继干涸,后虽入湖河流补给条件偶有改善,但萎缩干涸趋势明显[29].岱海1960s末以来水位持续下降,1970-1995年的25年中下降3.85m,湖泊面积也由160k m2缩小到109k m2[30].表2近50年来我国西部地区干涸消失的面积大于1k m2湖泊统计*T ab.2Sta ti

m2,1987年缩小至500k m2,湖泊蓄水量也从30.0@108m3下降到约7.0@108m3,湖水矿化度升高至116g/L[29].内蒙古呼伦湖,原是我国北方地区最大的淡水湖,面积达2339k m2,蓄水量138.5@108m3,是呼伦贝尔草原生态系统的重要支撑,也是国际重要湿地,近十多年来,湖泊水位下降,湖泊面积和蓄水量急剧减少,2010年湖泊面积仅1722k m2,蓄水量58.5@108m3,1960s以来,湖水p H值由8.5上升到9.1,湖水盐度由0.77j上升到2.5j,碱度由2.28mg/L上升到22.6mg/L[28].根据2008年调查数据与前期研究资料对比[1,31-33],随着湖泊萎缩,蒙新高原湖区湖泊整体上呈逐渐咸化的趋势,乌伦古湖从1950s到1980s末,矿化度一直在较高水平,1988年由于引额济海渠的开通,增加了乌伦古湖的入水量,虽使湖水矿化度较一度降低至2.14g/L,之后矿化度又逐渐增大至2008年的2.67g/L;吉力湖在1990s以前矿化度一直维持在0.5g/L左右,1990s末,由于入湖水量急剧减少,矿化度迅速升高至2008年的1.07g/L;岱海在1990s以前湖水矿化度增长相对缓慢,1962-1989年间增长了1.05g/L,之后快速升高,1990-2008年间增长了2.31g/L;艾比湖矿化度一直不断上升,从1950s的70g/L上升到2000s的120g/L,平均每年上升1.104g/L[34],近几年来迅速增大到151.8g/L;呼伦湖1970s前矿化度为0.77-0.99g/L,1988年为k

m2,流沙掩埋了大片农田和不少村庄.罗布泊、台特玛湖干涸直接成为盐碱沙地,使塔克拉玛干沙漠向东扩展,与库姆塔格沙漠连接成一片,造成严重的环境灾害[29].2.5湖泊与江河水力联系阻隔,生态功能退化除西部内陆流域一些封闭型湖泊外,我国大部分湖泊都与流域江湖有着自然的水力联系,河川径流不断补给湖泊,在维持湖泊正常水位和水量的同时,也为河湖水生生物繁衍提供了洄游通道,尤其是我国东部长江中下游平原湖泊,长江与两岸的湖群构成了独特的江湖复合生态系统,在维系江湖水生生态系统稳定和生物多样性等方面发挥着重要作用.近几十年来,受人类防洪蓄水工程建设和湖泊围垦利用等因素影响,湖泊与江湖自然水力联系被大坝或涵闸阻断,一些洄游性物种濒危或消失,水生生物多样性下降,湖泊环境净化与水量调节等生态服务功能不断退化.长江中下游是我国湖泊分布最密集的区域之一,尤其是大型浅水湖泊广布,历史上,这些湖泊大多与长江自然连通,发挥着正常的洪水调蓄和生物多样性维持等生态功能.随着湖泊泥沙淤积或沼泽化发展,一些湖泊与长江联系减弱,但丰水期仍然保持自然相通,1950s以来,人为修闸建堤等水利工程建设和围垦活动加剧,使得长江中下游绝大多数湖泊成为阻隔湖泊,目前仅有洞庭湖、鄱阳湖和石臼湖三个湖泊自然通江(表3).表3长江中下游部分面积大于10km2湖泊阻隔状况[1]T

非常感谢写手老师的帮助,这篇文章我很满意,现在就差两个小点要修改…麻烦写手老师了.A Research on the Factors and Development ofIntegrated Marketing Communications (IMC) IntroductionIMC is was first introduced by Don Edward Schultz, a professor in Northwestern University, who has been named one of the 80 Most Influential People in the Sales and Marketing World. Traditionally, IMC consists of a series of marketing methods, such as sales promotion, direct sales, ads, relationship between enterprises and the public as well as all other media platforms. The goal of IMC is to integrate these methods and materialize the best commercial effect for a specific product or service. Otherwise, the ultimate purpose of marketing is to deliver a higher standard of living (Kotler, 2003)[1].1. Definitions and functionalities1.1. The first major definition 没有提到自己对这两个定义的理解There are different views on how to define MIC. According to Association of American Advertising Agencies, A concept of marketing communications planning that recognizes the added value of a comprehensive plan that evaluates the strategic roles of a variety of communications disciplines - for example, general advertising, direct response, sales promotion and public relations - and combines these disciplines to provide clarity, consistency and maximum communications impact. Let’s analyze the definition and functionalities of elements forming IMC (Kotler, 2003) [2]. According to this definition, enterprises must mobile all possible tools and tap all resource and then they made an overall analysis to prepare and deliver. From my point of view, the key is to look at the whole picture, streamline the processing, figure out the best move to deliver the culture and spirit of an enterprise.1.2 .Another major definition of IMCBelch & Belch believes one voice, one look and image across all communications which defines the meaning of integrated marketing communications.One VoiceSome products own only one brand name in all cultures and languages across the globe, which enables them to gain widespread popularity easily. For example, the likes of UPS, P&G, Hp are typical successful enterprises that use their original pronunciations when promoting their products globally. Consumers unknowingly keep in mind these brands andcompanies as their names are frequently heard all over the world.I believe with uniform product appearance, images and names worldwide leave people stronger impression of the brand and easily familiarize consumers with the brand. It is focused on the impression recurrence, a psychological marketing tactic.2. Comparison between two major definitions2.1 The similarity between the two definitionsUniformity of marketing communicationThe marketing communications applied in the first definition features consistency while the second definition is characterized with highlight on product image, brands and interpretation across all cultures and languages, a kind of consistency for product quality. Definition 1 utilizes and optimizes all marketing vehicles to deliver one clear and consistent message.An identical business objectiveThe goal of marketing communication in any form is to promote a product, raise people’s awareness of the targeted product or service and shoot up the sales or business operation. Both definitions share the same objective in spite of the different approaches they respectively take.Maximization of the marketing effectMarketing communications are supposed to induce feedbacks from consumers. Generally speaking, the more attention a marketing practice could draw, then the easier a product or service can be recognized. Some companies adopt marketing the combined methods raised in definition 1 take into account every single possible factor, prioritize a host of marketing methods and come up with the best way to evoke people’s curiosity and willingness to consume. For example, McDonald, the biggest fast-food chained restaurant across the globe taps a variety of marketing vehicles to promote their food. They spend awful lot money on TV commercials, periodically launch discount for partial foods and roll out a series of toys or souvenir collection to spur people to buy their food. In definition 2, companies selling products or promoting their services rely on the repetition and globally uniform images to evoke more interest from consumer so as to push for sales. For example, Pepsi Cola, the second biggest beverage producer in the world holds onto their products overall uniformity. From the exterior, including the logo, bottle and color to its flavor, Pepsi remains the same across the globe. So, same colors, same logo, same English name and same color just easily imprint the characteristics of Pepsi Coke into the minds of many more consumers. All in all, both definition 1 and definition 2 aim to solicit the best public reaction and product awareness.2.2 The differences between the two definitions 这里讲的是disadvantage,并没有比较这两个定义之间有什么不同点Definition 1 highly highlights the significance of details along with combination of allpossible marketing means. So, as far as definition 1 goes, the culture, background, translation and religion will be covered and studied.Definition 2 insists on the visual and cultural uniformity over the course of marketing. It promotes the use of the same image, brand names, logo or translation across the whole with no regard to local culture, language or religion.Case: Auto giant Ford once launched a new type of vehicles in Latin America. The vehicle is named Feira. The Ford executive did not pay much attention to its meaning in Spanish, the most widely used language in Latin America. Three months after the vehicle made its debut, the sales was extremely low. After thorough investigation, Ford’s executive finally found that Feira means ugly old woman which was disgusted by people in Spanish-spoken countries. Then he immediately ordered a change of the name. In just one month, the vehicle sales witnessed a U-turn.On the other hand, if Ford’s executive followed the strategy cited in definition 1, then he would have done a background check on the meaning of brand name, logo and their translation in the targeted culture. Therefore, he could have prevented this misunderstanding from happening in the first place.From the above cases, we learn that the one name one logo marketing strategy will sometimes clash with regional culture. The first definition, which combines general advertising, direct response, sales promotion and public relation, could take into account all the details including perspective misunderstanding caused by cultural disparity.3. Driving force for IMCIn the 1990’s the global village has taken shaped thanks to the evolution of information industry, which coincided with the birth of IMC. Before 1990, enterprises all over the world consider advertisements, marketing, media, direct sales and promotion are independent factors. At the advent of the information revolution, enterprises realize they can not just separate these factors. On the contrary, they need to interweave these factors and come out with the optimal marketing mix to boost their enterprise image and product popularity [3]. At that point, the need for marketing communication integration first emerged. The internet was first connected in the year of 1994, from that moment onwards; new model marketing has come into being. If an enterprise still applies the separate methods to take up marketing, then they will have to spend a lot more money and resource and that the outcome may fall short of expectation.3.1. Major reasons for the growth of IMCFactor 1: Enterprises internal marketing reformThe need for marketing transformation inside an enterprise is the fundamental factor pushing for the application of IMC. For example, in the days ahead of the internet age, the major marketing strategies applied by Coca Cola encompassed TV commercials, posters,flyers and advertisements printed on various outdoor objects. In addition, Coca Cola organized a host of promotional events in shopping malls or any other place where the flow of customers is big. When it comes to public relation scheme, Coca Cola won over the officials and institutes by all means. It also from time to time, offered discount to consumers to boost sales. However, it did all of this in a separate manner as it never occurred to Coca Cola that integration of these marketing strategies could bring more merits. In that case, Coca Cola has spent a lot of resource and money on something costly but not necessary if it would realize the effectiveness of integrating all marketing communications. Public relation, ads, sales promotions are interconnected. They can raise the merit of each other and bring out the best in one another if properly handled. By maintaining a good public relation with the government and other non-profit organizations, Coca Cola could expand its popularity to more people from home and abroad. For example, by chipping in donation for disaster relief efforts, Coca Cola can gain more popularity and win over favors from the mass consumers. By showing more affection and kindness, the media will give it more positive assessment which could lead more people to trust it. A heightened public image combines regular promotional events, say offer giveaways or discounts to consumers. By doing this, it could largely to shoot up its sales.This is actually a process of dispersion. Coca Cola should combine all these marketing methods. Media, TV commercials, sales promotions should be united as one to optimize the general effect of marketing communications.Factor 2: The evolving needs of consumersThe second factor that drives up the growth of IMC is the ever-changing and ever-complicated needs from consumers. As long as people have needs for a certain product or service, IMC will prevail. Therefo re, people’s n eeds should be considered to be a basic driving force for IMC. In the past, major IMC methods manifested in the form of TV commercial and promotion sales. TV commercial can have a long-term influence. Many successful enterprises employ catchy commercial lines to have their products etched into consumers’ memories.With the advancement of technology prevalent in people’s life, their needs are getting more and more diverse and complex. Therefore, enterprises always need to work on their IMC to sell their products.There are a number of products of top brands on the street, say Channel cosmetics or LV handbag. People prefer buying them according to what mass media advertised. On the country, if your neighbor told you she prefer using cosmetics sold at the flee market, you probably would not follow her. This may because people have vanity and group psychology and always want to follow the fashion, and mass media can tell what the fashion is [4]. That is the effect of IMC, which makes the most of media effect. Therefore, vanity and group psychology among the general consumers are also an invisible force that pushes for the growth of IMC.Factor 3: The arrival of internet ageThe internet, which heralded its initial global connection in early 1990s, has changed theway people work and live. The old-school marketing methods like TV commercials are becoming less influential and less popular as more and more people prefer to use internet every day. How to make the most of the internet to communicate with consumers has become a hot topic. More and more enterprises turn to popular website to post their ads or organize online promotional activities. While a lot of search engines have become the hot advertisement spots for enterprises collect more popularity. As time progresses, a host of promising B2B website is mushrooming, which prompts the appearance of E-commerce. Nowadays, enterprises across the world flock to these B2B website to present themselves. In this case, the vehicles of marketing have been expanding given the internet is providing a myriad of channels for enterprises to communicate with consumers in the world. The cyber world has been exerting extensive influence on IMC, be it ads, direct sales, sales promotion or public relation development. The coordination, consistency and accuracy of IMC’s factors could optimize the cyber marketing communications for enterprises and vice versa.4. The development and outlook of IMCWith the rapid development of information technology, internet and media, IMC has been evolving over time. The scope of IMC is widening. Over 60 years ago, there was no television, the only marketing method is to sending out flyers, put up posters, billboards or spread ads on the radio. After the television was invented, marketers started using television to promote their products. Later, the emergence of internet was followed by mobile phone internet access. Some mass media today, like Television, has no powerful influence on audience or customers as interpersonal communication media like cell phone, MSN, BBS or other mouth marketing approaches. In that case, the traditional marketing communication approaches like Advertising will not as powerful as new marketing communication approaches like Direct Marketing or Personal Selling, etc (Alain Thys, 2009).The form of marketing is becoming unprecedentedly diverse and interesting. Marketers should integrate all marketing channels and figure out the best possible methods to maximize marketing effect.The world is entering an era of cyber media. So, the traditional advertisement agency and corporate marketing department should cope with the rapidly changing forms of marketing communication. The cyber media will bring about abundant information and diverse form of multi-media communications, which cover blogs, forum, IM, SNS, online video portal, etc. Agency and enterprises should keep a close eye on these mushrooming communications of wide diversity and swiftly broaden their marketing scope and communications. For instance, ad agency or enterprise should set up specific online forum to cater to the consumers’needs, a move could also arouse their curiosity and enable them to in on more information upon the enterprise, the brand and the products. For example, Dell, one of the major PC producers globally has introduced a website and forum. It also hires PC professionals to manager the forum, in which consumers can raise any questions regarding the computer or software. In response, the professionals could offer solutions or suggestions. Besides, these professionals periodically update information and PC knowhow on the forum to present a better service mode to users orprospective clients. Apple and Nokia will often resort to all sorts of online video portals to debut their latest products. It can help reach out to more prospective clients as these days, video portals like U-tube, has become one of the most visited websites with tremendous popularity and influence. So, the multi-media + internet mode is inevitably changing the way enterprises to market their products as IMC is diversifying. So, the cyber media is bound to be the future of IMC development. Who dominates marketing in the virtual world will dominate the market in life.If industries retain the old-school way to commit themselves to IMC, they will be easily edged out of the market. Cyber media is developing so fast that all industries should learn to beef up adaptability in a timely manner. The old-fashioned media or IMCs could not arouse people’s consumption desire any more. For those ad agency or enterprises that fail to transform IMC, their business performance will suffer and be eliminated over time. IMC will be transforming at an incredibly fast pace, enterprises should grasp the chances to innovate marketing communications. Otherwise, the one-time heavy competitor will be drowned by the mass and dazzling IMC applied by enterprises focused on IMC innovation.How IMC is going to evolve and what should we do to fit in?‘Can we adapt to the new market place? That's the hardest part. The economies are never going to go back to the way they were. The communication systems are never going to go back to the way they were. So we have to think about what transformations we need (Don Edward Schultz, 2009).’ [5] All in all, IMC strategy should be people-orientated and in conformity of market development.5.
