Ecologists use the term “succession ”to refer to the changes that happen in plant communities and ecosystems over time. The first community in a succession is called a pioneer community, while the long-lived community at the end of succession is called a a climax community. Pioneer and successional plant communities are said to change over periods from 1 to 500 years. These changes in plant numbers and the mix of species are cumulative. Climax communities themselves change but over periods of time greater than about 500 years.An ecologist who studies a pond today may well find it relatively unchanged in a year’s time. Individual fish may be replaced, but the number of fish may tend to be the same from one year to the next. We can say that the properties of an ecosystem are more stable than the individual organisms that compose the ecosystem.At one time. Ecologists believed that species diversity made ecosystem stable. They believed that the greater the diversity the more stable the ecosystem. Support for this idea came from observation that long-lasting climax communities usually have more complex food webs and more species diversity than pioneer communities. Ecologist concluded that the apparent stability of climax ecosystems depended on their complexity. To take an extreme example, farmlands dominated by a singe crop are so unstable that one year of bad weather or the invasion of a single pest can destroy their entire crop. In contrast, a complex climax community , such as a temperate forest, will tolerate considerable damage from bad weather or pests.The question of ecosystem stability is complicated, however. The first problem is that ecologist don’t all agree what “stability “ means . Stability can be all defined as simply lack of change. In that case, the climax community would be considered the most stable, since, by definition, it changes the least over time. Alternatively, stability can be defined as the speed with which an ecosystem returns to a particular form following a major disturbance, such as a fire. This kind of stability is also called resilience . In that case, climax community would be the most fragile and the least stable, since they can acquire hundreds of years to return to the complex state.Even the kind of stability defined as simple lack of change is not always associated with maximum diversity. At least in temperate zones, maximum diversity is often found in mid-successional stages, not in the climax community. Once a redwood forest matures, for example, the kinds of species and the number of individuals growing on the forest floor are reduced. In general, diversity, by itself, does not ensure stability. Mathematical models of ecosystems likewise suggest that diversity does not guarantee ecosystem stability- just the opposite, in fact. A more complicated system is , in general, more likely than a simple system to break down. (A fifteen-speed racing bicycle is more likely to break down than a child’s tricycle）Ecologists are especially interested in knowing what factors contribute to the resilience of communities because climax communities all over the world are being severely damaged or destroyed by human activities. The destruction caused by volcanic explosion of Mount. St. Helens, in the northwestern United States, for example , pales in comparison to theconstruction cause by humans. We need to know what aspects of community are most important to the community’s resistance to destruction, as well as its recovery.Many ecologists now think that the relative long-term stability of climax communities comes not from diversity but from the “ patchiness” of the environment. An environment that varies from place to place supports more kinds of organisms than an environment that is uniform. A local population that goes extinct is quickly replaced by immigrants from an adjacent community. Even if the new population is of a different species, it can approximately fill the niche vacated by the extinct population and keep the food web intact.2 According to paragraph 1, which of the following is not true of climax communities?A They occur at the end of a succession.B They last longer than any other type of community.C The numbers of plants in them and the mix of species do not change.D They remain stable for at least 500 years at a time.3 According to paragraph 2, which of the following principles of ecosystems can be learned by studying a pond?A Ecosystem properties change more slowly than individuals in the system.B The stability of an ecosystem tends to change as individuals are replace.C Individual organisms are stable from one year to the next.D A change in the numbers of an organism does not affect tan ecosystem’s properties.4 According to paragraph 3, ecologist once believed that which of the following illustrated the most stable ecosystems?A Pioneer communitiesB Climax communitiesC Single-crop farmlandsD Successional plant communities5 According to paragraph 4, why is the question of ecosystem stability complicated?A The reasons for ecosystem change are not always clear.B Ecologists often confuse the word “stability” with the word “ resilience”.C The exact meaning of the word “ stability” is debated by ecologists.D There are many different answers to the ecological questions.6 According to paragraph 4, which of the following is true about climax community?A They are more resilient than pioneer communities.B They can be considered both the most and the least stable communities.C They are stable because they recover quickly after major disturbances.D They are the most resilient communities because they change the least over time.7 Which of the following can be inferred from paragraph 5 about redwood forest?A They become less stable as they mature.B They support many species when they reach climax.C They are found in temperate zones.D They have reduced diversity during mid-successional stage.9 In paragraph 5, why does the author provide the information that “a A fifteen-speed racing bicycle is more likely to break down than a child’s tricycle”?A To illustrate a general principle about the stability of systems by using an every-day example.B To demonstrate that an understanding of stability in ecosystem can be applied to help understand stability in other situations.C To make a comparison that supports the claim that, in general, stability increases with diversity.D To provide an example that contradicts mathematical models of ecosystems.11 which of the sentences below best expresses the essential information in the highlighted sentence in the passage? Incorrect choices change the meaning in important ways or leave out essential information.A Ecologists now thinks that the stability of an environment is a result of diversity rather than patchiness.B Patchy environments that vary from place to place do not often have high species diversity.C Uniform environments can’t be climax communities because they do not support as many types of organisms as patchy environments.D A patchy environment is thought to increase stability because it is able to support a wide variety of organisms.Writing （30分）Some people think that strict punishments for driving offences are the key to reducing traffic accidents.

托福雅思作文英文
托福雅思作文英文1. In my opinion, traveling is one of the best ways to broaden one's horizons. It allows us to experiencedifferent cultures, meet new people, and explore unfamiliar places. Traveling gives us the opportunity to step out of our comfort zones and learn about the world beyond our own.2. When it comes to education, I believe that practical experience is just as important as academic knowledge. While studying in a classroom can provide a solid foundation, it is through real-life experiences that we truly learn and grow. Internships, volunteer work, and hands-on projects allow us to apply what we have learned and gain valuable skills that cannot be taught in a traditional classroom setting.3. Technology has undoubtedly transformed our lives in countless ways. From smartphones to social media, we are more connected than ever before. While technology has its benefits, it is important to strike a balance and not letit consume our lives. It is crucial to disconnect from screens and spend quality time with loved ones, engage in hobbies, and appreciate the beauty of the world around us.4. In my opinion, a healthy lifestyle is the key to overall well-being. Regular exercise, a balanced diet, and sufficient sleep are essential for maintaining physical and mental health. It is important to listen to our bodies and prioritize self-care. Taking care of ourselves allows us to be more productive, focused, and happy in all aspects of life.5. The importance of environmental conservation cannot be overstated. Our planet is facing numerous challenges, including climate change, deforestation, and pollution. Itis our responsibility to take action and make sustainable choices in our daily lives. Small changes, such as reducing waste, conserving energy, and supporting eco-friendly initiatives, can make a significant impact in preservingthe Earth for future generations.6. The power of positivity should not be underestimated.A positive mindset can greatly influence our outlook onlife and how we handle challenges. By focusing on the good, practicing gratitude, and surrounding ourselves with positive influences, we can cultivate a happier and more fulfilling life.7.

Whether it is through art, music, writing, or problem-solving, creativity allows us to think outside the box and find innovative solutions.

The Triumph of UnreasonA.Neoclassical economics is built on the assumption that humans are rational beings who have a clear idea of their best interests and strive to extract maximum benefit (or “utility”, in economist-speak) from any situation. Neoclassical economics assumes that the process of decision-making is rational. But that contradicts growing evidence that decision-making draws on the emotions—even when reason is clearly involved.B.The role of emotions in decisions makes perfect sense. For situations met frequently in the past, such as obtaining food and mates, and confronting or fleeing from threats, the neural mechanisms required to weigh up the pros and cons will have been honed by evolution to produce an optimal outcome. Since emotion is the mechanism by which animals are prodded towards such outcomes, evolutionary and economic theory predict the same practical consequences for utility in these cases. But does this still apply when the ancestral machinery has to respond to the stimuli of urban modernity?C.One of the people who thinks that it does not is George Loewenstein, an economist at Carnegie Mellon University, in Pittsburgh. In particular, he suspects that modern shopping has subverted the decision-making machinery in a way that encourages people to run up debt. To prove the point he has teamed up with two psychologists, Brian Knutson of Stanford University and Drazen Prelec of the Massachusetts Institute of Technology, to look at what happens in the brain when it is deciding what to buy.D.In a study, the three researchers asked 26 volunteers to decide whether to buy a series of products such as a box of chocolates or a DVD of the television show that were flashed on a computer screen one after another. In each round of the task, the researchers first presented the product and then its price, with each step lasting four seconds. In the final stage, which also lasted four seconds, they asked the volunteers to make up their minds. While the volunteers were taking part in the experiment, the researchers scanned their brains using a technique called functional magnetic resonance imaging (fMRI). This measures blood flow and oxygen consumption in the brain, as an indication of its activity.E.The researchers found that different parts of the brain were involved at different stages of the test. The nucleus accumbens was the most active part when a product was being displayed. Moreover, the level of its activity correlated with the reported desirability of the product in question.F.When the price appeared, however, fMRI reported more activityin other parts of the brain. Excessively high prices increased activity in the insular cortex, a brain region linked to expectations of pain, monetary loss and the viewing of upsetting pictures. The researchers also found greater activity in this region of the brain when the subject decided not to purchase an item.G.Price information activated the medial prefrontal cortex, too. This part of the brain is involved in rational calculation. In the experiment its activity seemed to correlate with a volunteer's reaction to both product and price, rather than to price alone. Thus, the sense of a good bargain evoked higher activity levels in the medial prefrontal cortex, and this often preceded a decision to buy.H.People's shopping behaviour therefore seems to have piggy-backed on old neural circuits evolved for anticipation of reward and the avoidance of hazards. What Dr Loewenstein found interesting was the separation of the assessment of the product (which seems to be associated with the nucleus accumbens) from the assessment of its price (associated with the insular cortex), even though the two are then synthesised in the prefrontal cortex. His hypothesis is that rather than weighing the present good against future alternatives, as orthodox economics suggests happens, people actually balance the immediate pleasure of the prospective possession of a product with the immediate pain of paying for it.I.That makes perfect sense as an evolved mechanism for trading. If one useful object is being traded for another (hard cash in modern time), the future utility of what is being given up is embedded in the object being traded. Emotion is as capable of assigning such a value as reason. Buying on credit, though, may be different. The abstract nature of credit cards, coupled with the deferment of payment that they promise, may modulate the “con”side of the calculation in favour of the “pro”.J.Whether it actually does so will be the subject of further experiments that the three researchers are now designing. These will test whether people with distinctly different spending behaviour, such as miserliness and extravagance, experience different amounts of pain in response to prices. They will also assess whether, in the same individuals, buying with credit cards eases the pain compared with paying by cash. If they find that it does, then credit cards may have to join the list of things such as fatty and sugary foods, and recreational drugs, that subvert human instincts in ways that seem pleasurable at the time but can have a long and malign aftertaste.Questions 1-6Do the following statemets reflect the claims of the writer inReading Passage 1?Write your answer in Boxes 1-6 on your answer sheet.TRUE if the statement reflets the claims of the writer FALSE if the statement contradicts the claims of the writerNOT GIVEN if it is possbile to say what the writer thinks about this1. The belief of neoclassical economics does not accord with the increasing evidence that humans make use of the emotions to make decisions.2. Animals are urged by emotion to strive for an optimal outcomes or extract maximum utility from any situation.3. George Loewenstein thinks that modern ways of shopping tend to allow people to accumulate their debts.4. The more active the nucleus accumens was, the stronger the desire of people for the product in question became.5. The prefrontal cortex of the human brain is linked to monetary loss and the viewing of upsetting pictures.6. When the activity in nucleus accumbens was increased by the sense of a good bargain, people tended to purchase coffee.

The three researchers are now designing the future experiments, which testA. whether people with very different spending behaviour experience different amounts of pain in response to products.B. whether buying an item with credit cards eases the pain of the same individuals compared with paying for it by cash.C. whether the abstract nature of credit cards may modulate the “con” side of the calculation in favour of the “pro”.D. whether the credit cards may subvert human instincts in waysthat seem pleasurable but with a terrible effect.Questions 10-13Complete the notes below.Choose NO MORE THAN THREE WORDS from Reading Passage 1 for each answer.Write your answers in boxes 10-13 on your answer sheet.To find what happens in the brain of humans when it is decidingthings to buy, George Loewenstein and his co-researchers did an experiment by using the technique of fMRI. They found that differentparts of the brain were invloved in the process. The activity in 10 was greatly increased with the displaying of certain product. Thegreat activity was found in the insular cortex when 11 and the subject decided not to buy a product. The activity of the medial prefrontal cortex seemed to associate with both 12 informaiton. What interested Dr Loewenstein was the 13 of the assessment of the product and its price in different parts of the brain.Don't wash those fossils!Standard museum practice can wash away DNA.1. Washing, brushing and varnishing fossils-all standard conservation treatments used by many fossil hunters and museum curators alike-vastly reduces the chances of recovering ancient DNA.2. Instead, excavators should be handling at least some of their bounty with gloves, and freezing samples as they are found, dirt andall, concludes a paper in the Proceedings of the National Academyof Sciences today.3. Although many palaeontologists know anecdotally that this isthe best way to up the odds of extracting good DNA, Eva-Maria Geiglof the Jacques Monod Institute in Paris, France, and her colleagueshave now shown just how important conservation practices can be. This information, they say, needs to be hammered home among the peoplewho are actually out in the field digging up bones.4. Geigl and her colleagues looked at 3,200-year-old fossil bones belonging to a single individual of an extinct cattle species, calledan aurochs. The fossils were dug up at a site in France at two different times — either in 1947, and stored in a museum collection,or in 2004, and conserved in sterile conditions at -20 oC.5. The team's attempts to extract DNA from the 1947 bones allfailed. The newly excavated fossils, however, all yielded DNA.6. Because the bones had been buried for the same amount of time, and in the same conditions, the conservation method had to be to blame says Geigl. "As much DNA was degraded in these 57 years as in the 3,200 years before," she says.7. Because many palaeontologists base their work on the shape of fossils alone, their methods of conservation are not designed to preserve DNA, Geigl explains.8. The biggest problem is how they are cleaned. Fossils are often washed together on-site in a large bath, which can allow water and contaminants in the form of contemporary DNA — to permeate into the porous bones. "Not only is the authentic DNA getting washed out, but contamination is getting washed in," says Geigl.9. Most ancient DNA specialists know this already, says Hendrik Poinar, an evolutionary geneticist at McMaster University in Ontario, Canada. But that doesn't mean that best practice has become widespread among those who actually find the fossils.10. Getting hold of fossils that have been preserved with their DNA in mind relies on close relationships between lab-based geneticists and the excavators, says palaeogeneticist Svante P bo of the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany. And that only occurs in exceptional cases, he says.11. P bo's team, which has been sequencing Neanderthal DNA, continually faces these problems. "When you want to study ancient human and Neanderthal remains, there's a big issue of contamination with contemporary human DNA," he says.12. This doesn't mean that all museum specimens are fatally flawed, notes P bo. The Neanderthal fossils that were recently sequenced in his own lab, for example, had been part of a museum collection treated in the traditional way. But P bo is keen to see samples of fossils from every major find preserved in line with Geigl's recommendations — just in case.13. Geigl herself believes that, with cooperation between bench and field researchers, preserving fossils properly could open up avenues of discovery that have long been assumed closed.14. Much human cultural development took place in temperate regions. DNA does not survive well in warm environments in the first place, and can vanish when fossils are washed and treated. For this reason, Geigl says, most ancient DNA studies have been done on permafrost samples, such as the woolly mammoth, or on remains sheltered from the elements in cold caves — including cave bear and Neanderthal fossils.15. Better conservation methods, and a focus on fresh fossils, could boost DNA extraction from more delicate specimens, says Geigl.And that could shed more light on the story of human evolution.GlossaryPalaeontologists古生物学家Aurochs欧洲野牛Neanderthal(人类学)尼安德特人，旧石器时代的古人类Permafrost(地理)永冻层Questions 1-6Answer the following questions by using NO MORE THAN THREE WORDS for each answer.1.

The failure of a high-profile cholesterol drug has thrown a spotlight on the complicated machinery that regulates cholesterol levels. But many researchers remain confident that drugs to boost levels of ‘good' cholesterol are still one of the most promising means to combat spiralling heart disease.2. Drug company Pfizer announced on 2 December that it was cancelling all clinical trials of torcetrapib, a drug designed to raise heart-protective high-density lipoproteins (HDLs). In a trial of 15000 patients, a safety board found that more people died or suffered cardiovascular problems after taking the drug plus a cholesterol-lowering statin than those in a control group who took the statin alone.3. The news came as a kick in the teeth to many cardiologists because earlier tests in animals and people suggested it would lower rates of cardiovascular disease. "There have been no red flags to my knowledge," says John Chapman, a specialist in lipoproteins and atherosclerosis at the National Institute for Health and Medical Research (INSERM) in Paris who has also studied torcetrapib. "This cancellation came as a complete shock."4. Torcetrapib is one of the most advanced of a new breed of drugs designed to raise levels of HDLs, which ferry cholesterol out of artery-clogging plaques to the liver for removal from the body. Specifically, torcetrapib blocks a protein called cholesterol ester transfer protein (CETP), which normally transfers the cholesterol from high-density lipoproteins to low density, plaque-promoting ones.Statins, in contrast, mainly work by lowering the ‘bad' low-density lipoproteins.5. Researchers are now trying to work out why and how the drug backfired, something that will not become clear until the clinical details are released by Pfizer. One hint lies in evidence from earlier trials that it slightly raises blood pressure in some patients. It was thought that this mild problem would be offset by the heart benefits of the drug. But it is possible that it actually proved fatal in some patients who already suffered high blood pressure. If blood pressure is the explanation, it would actually be good news for drug developers because it suggests that the problems are specific to this compound. Other prototype drugs that are being developed to block CETP work in a slightly different way and might not suffer the same downfall.6. But it is also possible that the whole idea of blocking CETP is flawed, says Moti Kashyap, who directs atherosclerosis research at the VA Medical Center in Long Beach, California. When HDLs excrete cholesterol in the liver, they actually rely on LDLs for part of this process. So inhibiting CETP, which prevents the transfer of cholesterol from HDL to LDL, might actually cause an abnormal and irreversible accumulation of cholesterol in the body. "You're blocking a physiologic mechanism to eliminate cholesterol and effectively constipating the pathway," says Kashyap.7. Most researchers remain confident that elevating high density lipoproteins levels by one means or another is one of the best routes for helping heart disease patients. But HDLs are complex and not entirely understood. One approved drug, called niacin, is known to both raise HDL and reduce cardiovascular risk but also causes an unpleasant sensation of heat and tingling. Researchers are exploring whether they can bypass this side effect and whether niacin can lower disease risk more than statins alone. Scientists are also working on several other means to bump up high-density lipoproteins by, for example, introducing synthetic HDLs. "The only thing we know is dead in the water is torcetrapib, not the whole idea of raising HDL," says Michael Miller, director of preventive cardiology at the University of Maryland Medical Center, Baltimore.Questions 1-7This passage has 7 paragraphs 1-7.Choose the correct heading for each paragraph from the list of headings below.Write the correct number i-ix in boxes 1-7 on your answer sheet.List of Headingsi.

Listening ComprehensionSection One：Listening Comprehension听力原文：Listen to a conversation between a student and his studio art professor.S: Professor Jones, good morning! Could I talk with you for a minute?P: Sure, Marty. What’s up? Is it about the class assignment this week?S: No, no... I’m almost done... really enjoying it.P: I’m glad to hear that.S: So, well, I’ve been talking to some of the other students in our studio art class and we were wondering who to talk to about maybe buying art supplies that are more environmentally safe for the art classes.P: Well, that’d be me. As the chair of the art department, I do have a say in purchasing decisions, but of course all decisions are voted on by the department faculty. You know... we already buy some eco-friendly products, for example, the easels in your painting studio. They’re made of wood from a South American eucalyptus tree. The trees grow really fast and new trees grow from the stumps of trees that have already been harvested. This is a great renewable resource.S: I didn’t know that. That’s fantastic! We are also considering drawing paper and pencils. There are some really cool companies that use recycled paper to make drawing paper and some pencil companies that make greener products out of wood from sustainable forests.P: Well, I can see you’ve done some research. Why don’t you write up a proposal? You can give us a list with the prices of the eco-friendly supplies you’d like the department to consider, and the faculty can compare that to the current cost of supplies at our next meeting.S: Oh, yeah ... I can appreciate that decisions will also be affected by the cost.P: Well, yes...that’s partly true. Of course, we have a budget for supplies and most of that money has been spent for this year, but you know, the university has been allocating additional funds for more eco-friendly practices. It’s part of their new ‘green campus’initiative.S: Yeah, the solar panels were recently installed on the roof of my dorm, and actually I read an article about the initiative in the campus newspaper. There’s a committee... I even heard there’s student representation that help in decision making related to the implementation of the university’s environmentally friendly practices.P: That’s right! The Green Committee and the solar panels you mentioned are just one of the many things they’ve done. So, I don’t know... given the university’s commitment to becoming more environmentally friendly and the fact that the university does receive partial funding from the state government to support this initiative... you never know!S: Ok... urn, when do you want the figures?P: Well, the next meeting of the art department faculty is at the beginning of next month. That gives you about three weeks.S: That should be enough time. We’ll get to work on it right away. Thanks for your help!1．Why does the student go to see the professor?A．To ask whether students can be represented at an upcoming faculty meeting B．To propose changing the kinds of supplies the art department usesC．To discuss an art project inspired by environmental concernsD．To complain about the lack of materials available to art students正确答案：B解析：目的主旨题。

Ecologists use the term “ succession ” to refer to the changes that happen in plant communities and ecosystems over time.The first community in a succession is called a pioneer community, while the long-lived community at the end of succession is called a a climax community. Pioneer and successional plant communities are said to change over periods from 1 to 500 years . These changes in plant numbers and the mix of species are cumulative.Climax communities themselves change but over periods of time greater than about 500 years.An ecologist who studies a pond today may well find it relatively unchanged in a year ’s time. Individual fish may be replaced, but the number of fish may tend to be the same from one year to the next. We can say that the properties of an ecosystem are more stable than the individual organisms that compose the ecosystem.At one time. Ecologists believed that species diversity made ecosystem stable. They believed that the greater the diversity the more stable the ecosystem.Support for this idea came from observation that long-lasting climax communities usually have more complex food webs and more species diversity than pioneer communities. Ecologist concluded that the apparent stability of climax ecosystems depended on their complexity.To take an extreme example, farmlands dominated by a singe crop are so unstable that one year of bad weather or the invasion of a single pest can destroy their entire crop.In contrast, a complex climax community , such as a temperate forest, will tolerate considerable damage from bad weather or pests.The question of ecosystem stability is complicated, however. The first problem is that ecologist don’t all agree what “stability “ means . Stability can be all defined as simply lack of change. In that case, the climax community would be considered the most stable, since, by definition,it changes the least over time.Alternatively,stability can be defined as the speed with which an ecosystem returns to a particular form following a major disturbance, such as a fire. This kind of stability is also called resilience . In that case, climax community would be the most fragile and the least stable, since they can acquire hundreds of years to return to the complex state.Even the kind of stability defined as simple lack of change is not always associated with maximum diversity. At least in temperate zones, maximum diversity is often found in mid-successional stages, not in the climax community. Once a redwood forest matures, for example, the kinds of species and the number of individuals growing on the forest floor are reduced . In general, diversity, by itself, does not ensure stability . Mathematical models of ecosystems likewise suggest that diversity does not guarantee ecosystem stability-just the opposite, in fact. A more complicated system is , in general, more likely than a simple system to break down . (A fifteen-speed racing bicycle is more likely to break down than a child’s tricycle)Ecologists are especially interested in knowing what factors contribute to the resilience of communities because climax communities all over the world are being severely damaged or destroyed by human activities.The destruction caused by volcanic explosion of Mount.St. Helens, in the northwestern United States, for example , pales in comparison to theconstruction cause by humans. We need to know what aspects of community are most important to the community ’s resistance to destruction, as well as its recovery.Many ecologists now think that the relative long-term stability of climax communities comes not from diversity but from the “patchiness”of the environment.An environment that varies from place to place supports more kinds of organisms than an environment that is uniform .A local population that goes extinct is quickly replaced by immigrants from an adjacent community. Even if the new population is of a different species, it can approximately fill the niche vacated by the extinct population and keep the food web intact.2 According to paragraph 1, which of the following is not true of climax communities?A They occur at the end of a succession.B They last longer than any other type of community.C The numbers of plants in them and the mix of species do not change.D They remain stable for at least 500 years at a time.3 According to paragraph 2, which of the following principles of ecosystems can be learned by studying a pond?A Ecosystem properties change more slowly than individuals in the system.B The stability of an ecosystem tends to change as individuals are replace.C Individual organisms are stable from one year to the next.D A change in the numbers of an organism does not affect tan ecosystem ’s properties.4According to paragraph 3,ecologist once believed that which of the following illustrated the most stable ecosystems?A Pioneer communitiesB Climax communitiesC Single-crop farmlandsD Successional plant communities5 According to paragraph 4, why is the question of ecosystem stability complicated?A The reasons for ecosystem change are not always clear.B Ecologists often confuse the word “stability” with the word “ resilience”.C The exact meaning of the word “ stability” is debated by ecologists.D There are many different answers to the ecological questions.6 According to paragraph 4, which of the following is true about climax community?A They are more resilient than pioneer communities.B They can be considered both the most and the least stable communities.C They are stable because they recover quickly after major disturbances.D They are the most resilient communities because they change the least over time.7 Which of the following can be inferred from paragraph 5 about redwood forest?A They become less stable as they mature.B They support many species when they reach climax.C They are found in temperate zones.D They have reduced diversity during mid-successional stage.9 In paragraph 5, why does the author provide the information that “a A fifteen-speed racing bicycle is more likely to break down than a child ’s tricycle”?A To illustrate a general principle about the stability of systems by using an every-day example.B To demonstrate that an understanding of stability in ecosystem can be applied to help understand stability in other situations.C To make a comparison that supports the claim that, in general, stability increases with diversity.D To provide an example that contradicts mathematical models of ecosystems.11 which of the sentences below best expresses the essential information in the highlighted sentence in the passage? Incorrect choices change the meaning in important ways or leave out essential information.A Ecologists now thinks that the stability of an environment is a result of diversity rather than patchiness.B Patchy environments that vary from place to place do not often have high species diversity.C Uniform environments can ’t be climax communities because they do not support as many types of organisms as patchy environments.D A patchy environment is thought to increase stability because it is able to support a wide variety of organisms.Writing (30 分)Some people think that strict punishments for driving offences are the key to reducing traffic accidents. Others, however, believe that other measures would be more effective in improving road safety.Discuss both these views and give your own opinion.。

Language barriers, unfamiliar customs, andgetting lost in a new city can make it a bit overwhelming. However, these challenges are what make the experience even more rewarding. Overcoming obstacles and adapting to new situations can build resilience and broaden your perspective.3. Another aspect of traveling that I find fascinating is the opportunity to learn about history and art.

Cyber love 雅思 托福 写作
Although the Internet is a virtual space, cyber love can never be an illusion. Meeting and falling in love with a person through the Internet is a popular way of communication in modern society. It deserves to be treated with respect.It is believed that the traditional love is human action, while online affection is based on an electronic medium. In other words, couples make use of the medium--the Internet to get to know each other. Though sharing the same basic function with the traditional marriage, cyber love still has a big advantage: extending greatly the association scope and the frame of reference, which is called the Marriage Circle in sociology. If the circle is too small, it restricts the evolution of human society. Therefore, the cyber affection has a huge positive effect.However, cyber love is a double-edged sword. On the one hand, it extends the space to make friends and gives people more opportunities of falling in love; on the other hand, the affection expressed through the virtual space can be false or sometimes insincere. Therefore, some people believe,compared with on-line affection, the traditional matchmakers are more trustworthy, and affection in real life is more stable.。
