雅思考試真題1
A.
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 activity in 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.

雅思考試真題2
Birthdays often involve surprises. But this year’s surprise on the birthday of the great British playwright William Shakespeare is surely one of the most dramatic.
On April 22, one day before his 441st birthday anniversary, experts discovered that one of the most recognizable portraits of William Shakespeare is a fake. This means that we no longer have a good idea of what Shakespeare looked like. "It’s very possible that many pictures of Shakespeare might be unreliable because many of them are copies of this one," said an expert from Britain’s National Portrait Gallery.
The discovery comes after four months of testing using X-rays, ultraviolet light, microphotography and paint samples. The experts from the gallery say the image—commonly known as the “Flower portrait” —was actually painted in the 1800s, about two centuries after Shakespeare’s death. The art experts who work at the gallery say they also used modern chemistry technology to check the paint on the picture. These checks found traces of paint dating from about 1814. Shakespeare died in 1616, and the date that appears on the portrait is 1609.
“We now think the portrait dates back to around 1818 to 1840. This was when there was a renewed interest in Shakespeare’s plays,” Tarnya Cooper, the gallery’s curator(館長), told the Associated President.
The fake picture has often been used as a cover for collections of his plays. It is called the Flower portrait because one of its owners, Desmond Flower, gave it to the Royal Shakespeare Company.
“There have always been questions about the painting,” said David Howells, curator for the Royal Shakespeare Company. “Now we know the truth, we can put the image in its proper place in the history of Shakespearean portraiture.”
Two other images of Shakespeare, are also being studied as part of the investigation(調(diào)查) and the results will come out later this month.

雅思考試真題3
1.Do you work or are you a student?
Im a student at Tsinghua University in Beijing.
Im a student, and Im a freshman in Tsinghua University.
Im a student, a high school student.
2.What subject are you studying?
Im studying for a Masters degree in Tsinghua University, specializing in the field of Math Studies.
3.Why did you choose that subject?
I chose math because I liked it in high school. I was always strong in math and science, so it seemed like a natural progression. Also, I did some research on career opportunities, and it seemed to be a subject with a promising future.
4.What would you like to do in the future?
I would love to be a teacher. Most of the women in my family are teachers, they have a huge impact on my life. I think it is wonderful to get to change peoples lives by what I say or do on the stage. It requires a person to be responsible and caring, and I want to be such a person.
5.What are the most popular subjects in China?
Its hard to say nowadays. You know, due to the globalization, our country is much more developed than ever. Every subject has something to offer to the society. Students just choose their subjects based on what they are interested in, which then, in turn, can become a trend.
6.Do you think its important to choose a subject you like?
Definitely! I think interest is the best motivator, if I choose something Im keen on, I will be willing to sacrifice my leisure time because it is a worthwhile sacrifice to me. In addition, when I face some difficulties, I will do my best to overcome the problems. Quitting in the middle will never be an option. We should consider carefully our choice from the start, rather than carelessly choosing the wrong path, then regretting it.
7.Are you looking forward to working?
I have been wanting to work full time, thats for sure. I can now imagine myself waking up early in the morning, getting my business attire on and sitting behind my office desk. I wonder how it feels to work with other professionals and with the boss always around… It could be stressful but interesting, I guess. The best part I would say would be to finally receive a salary and spend my own money. I would not have to bother my parents then. But, like most things in life, it really depends on what the job is and whether the environment is positive or not.
8.Do you like your subject? (Why? / Why not?)
Honestly, I dont. I am halfway through my college career. But reality struck me when the material we learned in class was much more difficult and the assignments werent fun. Im thinking about changing my own major now.
9.Do you prefer to study in the mornings or in the afternoons?
I am not a morning person, Im afraid. But to be honest, studying in the afternoon is even worse. I get really sleepy from one to four in the afternoon. So, actually, my brain is at its best in the evening. It works better then. I can stay sharp even until very late at night.
10.Is your subject interesting to you?
Absolutely. I find computer science really stimulating. Imagine creating something useful just using codes and numbers. It requires a good level of imagination and quite a good level of number skills, critical thinking and logic skills as well as a keen ability to solve problems.
11.Is there any kind of technology you can use in study?
For studying I use a computer and my phone. I often download research papers and read them on my phone and make notes onto the notes section of my phone too. I use my computer to actually write essays and do other homework tasks.
1.What work do you do?
I am a teacher at a high school. I started there in Jan 2015 after graduating from college. I would say it is a pretty challenging job.
2. Why did you choose to do that type of job?
Teaching is my passion. I dont view my career as a "job" per say. I see it more as my calling in life. It is my lifes purpose.
3. Do you like your job?
Definitely! I enjoy the variety and special projects where I can take ownership of the final product. My job provides me with both, so yes, it is a good job and I find it very rewarding.
Im not interested in my job… because it is so mundane and repetitive, two traits I despise and try to stay away from. I hope to find a better job that challenges me to aspire to new heights.
4. Do you miss being a student?
I definitely do! Sometimes I just wonder what would have happened if I had studied harder when I was in university. I just miss the days when I had nothing to worry about but the exams. Now, all the pressure from work and family is difficult to deal with.
5. Is it very interesting?
Most of the time, yes! The daily challenges from new projects provide constant opportunities to learn new things and to some extent re-invent myself. Every day is unique. My colleagues provide me with support but also healthy competition. I find my job most interesting when I am challenged to reach outside of my comfort zone.
6.Is there any kind of technology you use at work?
I use mainly a laptop computer and my phone at work. Sometimes I also use a photocopier scanner, and a video camera if Im making short promotional videos with my company. But mainly, I just use a computer.
7.Can you manage your time well when you work?
Yes, I am a project manager in my office, so I am quite good at managing my time and the other peoples time on the team. Ive worked as an IT manager for several years now.
8.Who helps you most at work?
My team members – I have a great team and they are all hardworking, supportive, smart and attentive to the needs of others and the project goals.

雅思考試真題5
Task：Some people argue that too much attention and too many resources are given to the protection of wild animals and birds.To what extent do you agree or disagree?
Sample answer：
In recent years, animal protection has become an issue of concern. People take different attitudes towards the increasing attention and expenditure on wildlife conservation. Some people suggest that the spending should be redirected to helping other fields in society. I agree with the view that the investment in wildlife protection is not worthwhile.
Animals, as a key component of the whole food chain, have a profound impact on the sustainability of an ecosystem. As we known, every kind of animals plays an important role in natural balance. For instance, the demise of any species will lead to the growth or decline of other species. In some extreme cases, some species may at the verge of extinction such as Dodo bird. If people did not take actions to protect wildlife as soon as possible, we humans would be affected in the end.
However, there are more issues that we need to focus in our society rather than protecting animals. In current social context, the primary task is still to improve living standards since there are many people living under the poverty line. Only when people are in a good living condition, can they pay attention to other social problems. Besides, technology and education are another two aspects of governments to concern. These two industries accelerate the development of society, which will provide a better protection for wildlife in turn.
In conclusion, although the animal is a significant part of ecosystem, it is better for governments to invest more finance and resources in other social problems.

雅思考試真題7
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.
Under pressure
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.
Going up
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.
