For the first time, scientists have made a robot that can take a beating and keep on going. Scientists from Cornell University made the robot, which looks like a spider (蜘蛛) with four legs.Until now, even the most advanced robot was almost certain to break down when it was broken. That is because its computer inside simply doesn’t know how to make the machine work after its shape has changed.To deal with this problem, the scientists put eight motors (发动机) and two sensors (传感器) that read how the machine is working. They all give signals (信号) to the machine’s software. Using this information, the computer can then work out the machine’s shape at any moment.The new technology is a big advance in robot-making, scientists say, and it’s far from scary. It may someday help scientists create better man-made (人造的) arms and legs and give new freedom to people who losethem. It might also help scientists understand how people and animals work out their own sense of place in space.“It has been difficult to design robots that can work well when the environment changes or when it’s damaged,” says Olaf Sporns of Indiana University in the US. “With this work, we are nearer to solving this problem.”1．（小题1）Why do robots easily break down when they are damaged?A．They have no computers inside.B．The computer has changed a lot.C．They cannot repair themselves.D．The computer cannot work if the robot changes.2．（小题2）The new technology allows the robot to .A．do house work for humansB．tell people where it isC．remember a lot of informationD．keep working after being damaged3．（小题3）The underlined word “them” in Paragraph 5 refers to.A．sensors B．arms and legs C．scientists D．robots4．（小题4）How do the sensors in the robot work?A．They help the computer learn the robot’s condition.B．They can find out where the damage comes from.C．They can replace (替代) the computer when it’s broken.D．They can send signals to the person who uses the robot.C15、One day when the government officials（官员）were rebuilding a barn（谷仓）, they found a mouse hole in a corner and used smoke to force the mice inside the hole to come out. A while later they saw mice running out, one after another. The strange thing was that after two mice came out of the hole, they did not run away quickly. Instead, one chased after the other near the exit of the hole. It seemed that one was trying to bite the tail of the other’s.Everyone was puzzled, so they stepped closer to take a look. They realized that one of the mice was blind and could not see anything, and the other one was trying to allow the blind mouse to bite on his tail, so he could pull the blind one with him to escape. Everyone said nothing and was lost in thought. During the mealtime, the group of people sat down in a circle and started to chat about what happened between the two mice.One official said, “I think the relationship between those two mice was that of emperor and minister（大臣）.”A smart young man said,“I think the relationship between those two mice was husband and wife.”A Chinese said,“I think the relationship between those two mice was that of mother and son.”At that moment, one Samaritan（善人）asked,“Why did those two mice have to have a certain relationship ?”Suddenly, the atmosphere（气氛）froze, in fact, the true love is not based on money, friendship, loyalty or blood relationship. Instead, it is based on no relationship.1．The government officials used to force the mice to come out.A．drugs B．delicious food C．water D．smoke2．Why did one mouse chase after the other near the exit of the hole ?A．They were fighting for food. B．They were biting each otherC．The one wanted to help the other to escape. D．They gave up escaping.3．What did the government officials talk about during the meal ?A．How to rebuild the barn.B．What they did with the mice.C．What the relationship was between the two mice.D．How they made the mice inside the hole come out.4．The underlined word“loyalty”probably means .A．地位B．职业C．亲情D．忠诚5．We can infer（推断）from the passage that .A．maybe the two mice had no relationship, but had true loveB．what the smart young man said was rightC．a mouse is as clever as a manD．the two mice were mother and sonD16、I have come to realize that life is a long journey. Whether we choose to keep moving around, or we choose to stay in one place, we are on a journey. That journey is not an easy one because every day it makes us face new problems in new ways.When I was a little boy, I always looked forward to the next trip or the next holiday. Maybe it is because we lived in a small and boring town. When I finished school, I kept moving. In the first year out of school, I travelled with a friend and we visited over 17 countries in Europe, working in different jobs as we went. After this, I started studying. I studied at three different universities and lived in five different towns. That was my life. There was always someone else to get to know. All this carried on for many years until I got married and had my own family. When you stay in the same place, with the same persons, you start a whole new journey.Then you will stay in the same town, choosing one place to live and one job to remain in. There you are challenged to face life, doing things such as trying hard to get along well with your boss. Y ou have to keep on at your job when you feel like giving it up and traveling again.So rather than move around on different trips, you are on a new journey. This journey of staying still is just as important as all the travels in the world.1．Why did the writer like moving around when he was a boy?A．Because he liked being with friends.B．Because he wanted to know about the world.C．Because he lived in a boring and small town.D．Because he didn’t love his family.2．Which one is TRUE according to the passage?A．The writer went to Europe alone when he left school.B．The writer kept moving during his whole life.C．After the writer got married, he tried different jobs.D．The writer thinks staying still is as important as traveling around.3．What is the best title?A．Go traveling B．Life is a long journeyC．Stay still D．Travel makes you betterE17、Scene 1On a wild mountain, two goats met on a rock just over a high cliff (峭壁). The rock was so narrow that there was neither room for them to pass each other nor to turn round and go back.One of them with great care laid himself down on the narrow rock, pressing as close to the rock as he could. Then the other goat gently and softly stepped over his friend, till, safely past him, he could lightly get away.The goat that had lain down then drew himself up, safe and free to leap again from rock to rock, and eat the sweet grass on the hills.Scene 2Two other goats met on the banks of a wild, rushing stream. They found there was a tree across the stream. It formed a bridge from one side to the other.They stood for a moment with one foot on the tree, each thinking that the other would draw back. But neither of them would give away, and they met at last on the middle of the narrow bridge!They then began to push and fight with their horns (犄角), till at last their feet slipped, and both the goats fell into the stream, and were lost in the waters!Both might have been saved if either of them had known how to give way to another at the right time.1．（小题1）How did the two goats in Scene 1 manage to get away from the rock?A．One goat turned around and went back.B．One goat jumped over the other and walked away.C．They stood there and passed the rock carefully together.D．One goat lay down on the rock so that the other could first leave.2．（小题2）Which of the following shows the right order in Scene 2?a.

They met on the middle of the narrow bridge.A．b-c-e-a-d B．b-c-e-d-aC．c-b-e-d-a D．c-e-b-d-a3．（小题3）What can we learn from the passage?A．Many hands make light work.B．Actions speak louder than words.C．Don’t put all your eggs in one basket.D．Being kind to someone is never a waste.F18、As traditional Chinese art, paper cutting has a long history. The first and earliest paper cutting was found in China 1,500 years ago. But this traditional art is at risk of disappearing now.

I went to an American college a year ago. Yet I did not know the real American society until I was hurt in a car accident because after the accident I had to see a doctor and go to court(法院).After the accident, my roommate called a doctor for me. I was very grateful and decided to repay him one day. But the next day, he asked me to pay him $200 for what he had done. I was amazed. He had good reason to charge me, he said. And if I wanted to collect money from the person who was responsible(负有责任的) for my accident, I’d have to have a good lawyer. And only a good doctor can help me get a good lawyer. Now that he had helped me find a good doctor, it was only fair that I should pay him. But every day I went to see the doctor, I had to wait about 50 minutes. He would see two or three patients at the same time, and often stop treating one so as to see another. Yet he charged me $115 each time. The final examination report consisted of ten lines, and it cost me $215. My lawyer was all smiles the first time we met. But after that he avoided seeing me at all. He knew very well the other party was responsible for the accident, yet he hardly did anything. He simply waited to collect his money. He was so irresponsible that I decided to refuse his help. And he made me pay him $770.Now I had to act as my own lawyer. I told the insurance(保险)company the date I was leaving America because of my inexperience(缺少经验). Knowing that, they played for time and I left without getting a cent.My experiences taught me two things about America: firstly, in a country like America money is everything. It is more important than friendship, honor or professional morality. Secondly, foreigners are still being unfairly treated.

But do you know that it is bad for both your physical and mental health? A recent study shows that telling fewer lies helps people physically and mentally.“For ten weeks, 110 people aged from 18 to 71 were tested to see the relationship between the number of lies they told and their health,” said Anita Kelly, a professor at the University of Notre Dame in Indiana. “When they lied more, their health declined,” said Kelly.Researchers divided the people into two groups. Group A was told to avoid telling any lie for any reason to anyone. They may omit (忽略) the truth, refuse to answer questions, and keep secrets, but they can’t say anything that they know are not true. Group B was not told anything like this.Over the study period, when people in Group A told fewer lies in a week than they did in other weeks, they experienced fewer health problems such as sore throats and headaches. Professor Linda Stroh said, “When you find that you don’t lie, you have less stress (压力).” The results of past research show that each American tells about 11 lies a week. In both groups, when people lied less during a week, they reported better physical and mental health during that period.“It’s certainly a good thing to have people be more honest,” said Robert Feldman of the University of Massachusetts. “It may improve our mental health, but I don’t think it can improve our physical health.”1．The underlined word “declined” means “________” in Chinese.A．变坏B．改善C．加强D．混乱2．From the second paragraph, we can learn that ________.A．the test continued for no more than one monthB．older people lie less than younger peopleC．the number of lies one tells can affect one’s healthD．many people feel sick when th ey don’t tell lies3．People in Group A were allowed to ________.① omit the truth ② refuse to answer questions③ keep secrets ④ tell lies to strangersA．①②③B．②③④C．①②④D．①③④4．According to Linda Stroh, ________.A．mental health is more important than physical healthB．when people don’t lie, they feel more relaxedC．to be honest can’t improve our physical healthD．telling lies is necessary sometimes5．We would most probably find this passage ________.A．on a travel website B．in a story bookC．in a health magazine D．in a cookbookE17、Imagine the situation. You are driving along a desert or on a mountain. You have no idea where you are. You passed the last house two hours ago. Then your car breaks down. It is night and it is cold. You have no mobile phone. What do you do? Well, next time take a GPS with you. This invention may be able to help you. It is a device(装置) which uses satellites (卫星) to find the user’s position(位置). It can find your position to within 20 metres. A GPS cannot start your car, but at least you will know where you are.GPS, which means Global Positioning System, is a small radio receiver. It looks like a mobile phone. You can hold it in your hand, or put in your pocket. It is sometimes put into a watch or a telephone. We also find GPS devices in cars, planes, or boats. Some of these devices have electronic maps, so you know where you are. For example, in a city they can tell you the name of the street.There are three parts to the Global Positioning System. The first part is the receiver. Y ou can hold it in your hand, or have it fixed into your car, plane, etc. The second part is a group of satellites orbiting the Earth. The receiver contacts at least four of the satellites and calculates(计算) its position. The third part of the system is a network of ground stations.____are all over the world. They control the satellites and make sure they are working well.Some people think that in the future the GPS will be as common as the mobile. They are becoming cheaper and moreand more accurate(精确的). There are also new uses for the GPS. Perhaps they will become like watches. Everyone will have one and you will never be lost again.1．According to the passage, with the help of the GPS, people ________.A．can’t be lost in a new cityB．can’t find their way in different countriesC．can learn about the culture of an unknown placeD．can spend the least time getting to another place2．We can learn from the passage that ______.A．there are three parts to the GPSB．a GPS can’t be put into a watchC．a GPS can help you start your carD．the GPS are becoming more and more expensive3．The underlined word “They” in paragraph 3 means “________”.A．Receivers B．GPS devicesC．Satellites D．Ground stations4．The passage is mainly about _____.A．the history of the GPS B．the introduction of the GPSC．the shape of the GPS D．the three parts of the GPS5．What can we infer(推断) from the passage?A．All GPS devices have electronic maps.B．People in many countries will use the GPS for free.C．The receiver of the GPS contacts at least five of the satellites.D．The GPS will become more and more common in everyday life.F18、Could smells affect your lifespan? Female fruit flies (果蝇) without the ability to smell food live longer than other fruit flies．The sense of smell may be connected to the cellular ageing (细胞老化) process in many other living things even people．Such connection has recently been found in both worms and flies．For example, scientists found that removing fruit flies' ability to smell made them live nearly 10 percent longer than flies with a sense of smell．They confirmed that food smells were the ones most likely to affect ageing, as nutrition (营养) and lifespan are known to be connected in many living things．To test the idea that food smells affect lifespan, they removed flies' ability to smell carbon dioxide, which is produced by some fly foods．They left the rest of the smelling system．This action had no effect on male flies, but the females lived 30 percent longer than normal．Removing the ability to smell CO1 may stop flies getting information about food availability．This could mean that food is not enough, causing processes that encourageflies to survive．Scientists found that the female flies from stored extra fat and that both males and females immune (免疫) to CO1 were stronger against the stress than normal flies．It is suggested that females may simply be easily influenced by the smells of CO1．Scientists point out that people don't know whether ageing and smell are connected in animals and humans．But they clearly experience physical changes after smelling food．2．From the passage, we learn that what scientists found is to ________．A．show there is the best way to make lifespan longerB．tell us we should remove our smell ability to live longC．show the sense of smell can affect the cellular ageing processD．explain fruit flies without ability to smell can live longer3．Scientists do some research to proveA．the immune system of flies to CO1B．the connections between nutrition and lifespanC．the importance of food smells to our humansD．the connections between food smells and lifespan4．According to scientists' opinion, we can see that ________．A．flies without ability to smell is encouraged to store extra energyB．male flies in general can live longer than female onesC．both male and female flies can live longer without the ability to smellD．flies without ability to smell can also get information about food availability5．Which of the following best describes the passage as a whole?A．CO1 has few effects on female flies．B．The sense of smell might have an effect on living things．C．The sense of smell is necessary to humans' health．D．Female fruit flies can always live longer than male flies．Ⅴ.书面表达19、书面表达。

But it is totally different in Canada. The government encourages people of any age to volunteer in public and make contributions to the wholesociety. Therefore, if students want to graduate from high school, 30 hours of volunteering is required. If students want to get into a good university, it helps if they contribute a lot to society. Volunteering is an important factor that universities will take into consideration.Furthermore, there are volunteer opportunities everywhere. People can find information about how to volunteer posted in the library or on the Internet. It includes many different jobs, such as wrapping gifts in a shopping mall, taking care of small kids or cleaning up a church. Students can choose what they want to do and register(注册) on line.I got my first volunteering job in New Westminster Museum every Sunday from 9:30am to 11:30 am. My job is to proofread the documents on a laptop and correct mistakes. The museum is about the history of the Irving Family, a historically important family in New Westminster. At first, I was nervous to communicate with others. But as time passed I became more open. During volunteering, I not only learned how to work with other volunteers, but also learned a lot of history about New Westminster.As a volunteer, I am proud of myself. I enjoy doing my job and helping others.1．From the first paragraph, we know _________ in Canada.A．being a volunteer can earn a lot of moneyB．students can graduate form high school without doing volunteeringC．the student who contributes a lot to society may have a chance to enter the good universityD．the government only ask adults to be volunteers.2．The writer spent ________ hours when she did her first volunteering job.A．2 B．3 C．4 D．53．The underlined phrase “proofread the documents” means _________ in the third paragraph?A．起草文件B．校对文件C．打印文件D．发送文件4．The writer wrote the article mainly to _________ .A．introduce the volunteering in Canada.B．describe where can find volunteer opportunitiesC．show that she learned a lot from being a volunteerD．compare her first volunteering job with other jobs to show their differences5．The best title of the article maybe “ _________ ”.A．Volunteering in CanadaB．Where to find a volunteering job in CanadaC．The best way to find a volunteering job in CanadaD．Students in CanadaC15、Emma and Hannah are 13-year-old school girls from Minnesota, USA．They are good at making new things both of them are also good at sales. They are selling charms (小装饰物) made out of bottle caps.The girls came up with the idea last summer when they saw charms were popular with kids. They talked with their parents about the idea. Since then they have sold enough charms to buy a bike for Hannah.The girls collect bottle caps and then clean them. They find some interesting pictures on the Internet or on paper, and then glue them onto the inside of the caps. There are different kinds of pictures, “Peace signs are popular with girls, and single-letter charms are popular with boys whose names start with those letters,” Emma and Hannah said.Now, charms can be found eve rywhere at Dakota Hills Middle School in Eagan. “Students put charms on purses, backpacks, and their lunch boxes,” said Emma. Emma and Hannah also have a shop on the Internet. They hope they can sell their charms to more kids. They’re thinking about sellin g their charms at the Eagan Market Festival next summer.Their business is not only for getting money. At their Valentine’s sale, 20% of the income (收入) went to charity. 1．When _______ did the girls begin to sell the charms?A．About a year ago. B．About two months ago.C．Nearly fifty days ago.

D．They hope to sell charms in every school.4．Which of the following is TRUE?A．The two girls love their parents and money. B．Boys like charms with signs.C．They won’t sell charms next summer.D．The charms are popular with students.D16、Usually, students are not encouraged to run or jump around in the corridor (走廊). However, students in a British grammar school really enjoy running on the corridor tiles (瓷砖) and their teachers even encourage them to do that. Why? It is because the corridor was built with special kinetic (动能的) tiles. When students jump on the tiles, electricity will be produced. After one year, the electricity produced from the tiles can fully charge 853 mobile phones or power(供电) an electric car to drive seven miles. It’s amazing, isn’t it?The corridor tiles are really a brilliant invention. Students can not only play on the corridor, but also help power the lights in their school corridors and other equipment in their classrooms. Besides, this is a good way to teach students tobe creative. They will beinspiredto be scientists, inventors and engineers in the future to find clean energy for all humans.The inventor of the magic corridor tiles is Laurence Kemball-Cook. He was once a student in this school. Now, he is CEO of his own company. The corridor tiles are not Laurence’s only invention. He has also inv ented a special dance floor, which can be used at music festivals. It allows dancers to charge their mobile phones while they are dancing on the dance floor.1．Why do the students in the passage enjoy running on the corridor tiles?A．Because the corridor tiles are expensive.B．Because the teachers ask them to do that.C．Because the corridor was built with special tiles.D．Because students like running and jumping.2．After one year, the electricity produced from the tiles can provide enough energy for _______.A．over 800 mobile phonesB．all the lights of the schoolC．an electric car to drive 70 milesD．the lights and other equipment in their classrooms.3．The underlined word “inspired” most probably means “ _________”.A．encouraged B．forcedC．trained D．allowed4．What else has Laurence invented besides the corridor tiles from the passage?A．A mobile phone. B．A music player.C．An electric car D．A special dance floor.5．According to the passage, which of the following statements is TRUE?A．Students are not allowed to walk in the corridor.B．Laurence once studied in the British grammar school.C．Laurence has more than one company of his own.D．All the corridor in British schools was built with special kinetic tiles.E17、At present, more and more people are crazy about travelling. Why do people travel? ＂The world is so big thatI want to have a look.＂many people would say. But travelling abroad now means much more than that for the growing number of Chinese tourists. Of course it offers us good opportunities to meet people from other countries, learnabout their culture and customs.According to the United Nations World Tourism Organization (UNWTO), more than 1 billion people travelled to another country in 2012. In 2012, Chinese people travelled abroad 30 percent more than in 2011. In 2014, the number of outbound tourists has reached over 100 million for the first time. Compared with 2013, it has increased by 19.49%. Chinese has ranked first as the main source of the world tourism according to the report. The prosperity (繁荣) of the tourism industry can also bring both our country and foreign countries great economic benefits. Chinese people usually travel abroad in large tourist groups and visit several countries in one trip.Chinese people don’t just tra vel for sightseeing. The China International Travel Service Company said that all their tour trips sold out a month before Christmas Day. Stores offered discounts(打折) during that time, so shopping in Europe and the United States is popular among Chinese travellers.In December, China is going through a very cold winter. So many people like to go to some countries in Southeast Asia because the weather there is quite pleasant.The improvement of living standards means more Chinese can travel abroad. But many of them don’t have a sense of public manners. A report by Living Social website in March 2012 even listed Chinese as the world’s second worst tourists.If you want to change that bad name, remember to avoid the following: littering, spitting, snatching bus seats,line-jumping, taking off shoes in public, talking loudly and smoking in non-smoking areas. Besides, we should learn some necessary manners of foreign countries.1．Which of the followings is not the reason why Chinese people travel abroad?A．To have a look at the word.B．To shop abroad.C．To bring foreign countries great economic benefits.D．To learn about foreign culture and customs.2．How do Chinese people usually travel abroad?A．In small groups and visit one country in one trip.B．In large groups and visit several countries in one trip.C．In small groups and visit several countries in one trip.D．In large groups and visit one country in one trip.3．The underlined word ＂outbound＂in the passage probably means _______.A．outside the station B．going outC．going towards D．going abroad4．Which of the following is right according to the passage?A．Chinese has ranked second as the main source of the world tourism according to the report.B．A report by Living Social website in March 2012 even listed Chinese as the world’s worst tourists.C．Chinese people like to travel before Christmas because of the cold winter in China.D．People choose to some countries in Southeast Asia in winter because of the nice weather there.5．What can we infer from the passage?A．Many of Chinese people behaved badly when traveling abroad.B．In 2013, the number of outbound tourists is larger than that in 2014.C．Chinese people won the bad name because too many Chinese people buy discount things before Christmas.D．We have to change names when we travel abroad.F18、When I was a child, I often dreamed of the time when I could leave home and escape to the city. We lived on a farm and, in the winter especially, we were quite cut off from the outside world. As soon as I left school, I packed my bags and moved to the capital. However, I soon discovered that city life has its problems too.One big disadvantage is money---it costs so much to go out, not to mention basics like food and housing. Another disadvantage is pollution. I suffer from asthma(哮喘), and at times the air is so bad that I am afraid to go outside. Then there is the problem of travelling round. Although I have a car, I seldom use it because of the traffic jams. One choice is to go by bicycle, but that can be quite dangerous.Of course there are advantages. First, there is so much to do in the city, whatever your tastes in culture or entertainment. Besides, there are wonderful jobs and greater chances of moving to a more important job or position. Finally, if you like shopping, the variety of goods is very surprising---and, what is more, shops are often only a short walk away.Is life better then, in the city? Perhaps it is, when you are in your teens(十几岁) or twenties. However, as you get older, and especially if you have small children, the peace of the countryside may seem better. I certainly hope to move back there soon.1．What was the writer always thinking about when he was a child?21*cnjy*comA．Staying on the farmB．Moving to the countrysideC．Leaving home for the cityD．Running away from the school2．Which of the following is true about the writer?A．He is very old now.B．He is in good health.C．He prefers driving a car.D．He lives in the city now.3．In the passage, the writer tries to _______.A．express his opinions about way of lifeB．describe his life in the countrysideC．show an interest in the outside worldD．ask the reader to live in the city4．How is the passage mainly developed?A．By inferring B．By comparingC．By listing examples D．By giving explanations2Ⅴ.书面表达19、书面表达今年的奥斯卡，在陪跑22年之后，莱昂纳多(Leonardo DiCaprio)终于抱得了他人生的第一座奥斯卡小金人。

He never had time to play football with me.During my high school and college years, I worked with my family at night. But I always avoided the kitchen. I couldn’t wait to graduate (毕业)so that I could move away from the family business. Several days before my graduation day, my father and I started looking at new cars. Finally, we found the right car. I was sure that my father would give it to me as my graduation gift.On my graduation day, my father gave me a book as a gift. It was his old cookbook. I was so angry that I gave it back to him and ran out of the house. Several days later I moved away and started my business. Although I often saw my father during holidays, we never talked about the graduation gift. Then one day, I got a call that my father was ill. I went to see him because I was very worried.That night, I looked through my father’s books and saw the cookbook that he had given me year before. I carefully opened the cookbook and went through it.

But they had to keep the fires burning（燃烧）, for they couldn't start it again if there was no lightning. Later, they found out hitting two pieces of stones（石头）together could make a spark（火花）. The spark could fire dry leaves（树叶）. In this way they could make the fire again if it went out. Then people also learned to make a fire by rubbing（摩擦）. They made a hole on a big piece of wood（木头）and put a smaller stick（树枝）into the hole. They turned the stick again and again. After a few minutes they got a fire.As years went by, people learned other ways to make a fire. Sometimes they used the heat（热）from the sun. They held a piece of glass in the right way and made a piece of paper on fire.About two centuries（世纪）ago，people began to make matches（火柴）. Matches brought people a quick and easy way to make fires. Today matches are still being used, but people have more new ways to make fires. One of them is to use an electric（屯子的）fire starter.

Last year, he taught his students about the world’s rain forests. They learned that rain forests are important because the plants and animals of the rain forest give us food, wood, and medicine.Destruction of the world’s rain forests is a serious problem. Unluckily, rain forests are disappearing at a rate of 80 acres per minute! As part of a class project, Myers’ students bought three acres of rain forest in Central America. They paid $25 per acre. The students hope that the land they bought will be protected and not destroyed. The students became so interested in rain forests that they decided to get a closer look at a real rain forest.So last June, Myers and four of his students took a boat ride down a river. They saw alligators and crocodiles. In the middle of the week, a guide took Myers and his students into the rain forest. “The monkeys were not happy that we were in their forest. They broke small branches off the trees and threw them at us,” one of the students said, “It was a great learning experience for all of us,” said Myers.Each student chose something specific about Costa Rica to study involving the plants, animals, food, and culture.During the last few days the group had time to do fun activities. They went whitewater rafting and horseback riding, and visited Costa Rica’s active volcano.Myers hopes to make the trip every year with a different group of kids.1．How much did Myers’ students pay for the rain forest they bought?A．$25 B．$75 C．$80 D．$20002．What did Myers and his students do at the beginning of the trip?A．They went into the rain forest.
