A

United Nations Climate Change Conference

The U.N. Climate Change conference opened in Copenhagen, Denmark on Dec.7th with some 15,000 delegates and observers from nearly 200 countries attending what is called the last best chance for an agreement to combat(与……战斗) global warming.

Their aim is to find common ground, including on reduction of greenhouse gas emissions, promotion and transfer of new more eco-friendly technology and the necessary funding to make this possible, especially for the less developed and poorer nations.  It also means coming up with long term vision and cooperation for the future.

Most scientists believe the warming trend is mainly caused by human activity, especially the use of fossil fuels(矿物燃料) and the cutting down of forests. Skeptics(怀疑论者) say global warming is part of a natural cycle of climate change.

In Copenhagen, experts and officials alike are putting the emphasis on what people and governments can do to cut the emission of greenhouse gases.

Scientists say a 25 to 40 percent cut in carbon-dioxide emissions is needed to control global warming. The European Union, China, and India have already pledged(保证) reductions. The United States is waiting for Congressional(国会的) approval for a proposal put forward by the Obama administration.

Barack Obama, President of the United States said, “Each of us must do what we can when we can to grow our economies without endangering our planet -- and we must all do it together. We must seize the opportunity to make Copenhagen a significant step forward in the global fight against climate change..”

Desmond Tutu, Archbishop of South Africa said, “Worldwide, we have the chance to start turning the tide of climate change, but only if all governments commit themselves to a fair, binding(有约束力的) and sustainable climate agreement in Copenhagen.”

56. From the first paragraph we can infer that___________.

people think that this conference is of no use

this conference is the last one to be held about the climate change

before this conference some countries fight against each other.

people expect a final agreement will be achieved

57. Which is NOT included in the aim of this conference?

A. To reduce the emission of the greenhouse gases.

B. To develop the agriculture and industry of the developed countries.

C. To cooperate with each other for the future.

D. To transfer new more eco-friendly technology.

58. Which statement is TRUE according to the passage?

A. The United States refuses to reduce the emission of greenhouse gases.

B. The European Union is waiting for a proposal put forward by Obama.

C. China and India have already agreed to cut carbon-dioxide emissions.

D. South Africa doesn’t think much of this conference.

59. What is Obama’s attitude according to his words?

A. Doubtful.                          B. Positive.     C. Negative.                    D. Regretful.

60. _________is the reason of global warming according to the skeptics.

A. Human activity                  B. Fossil fuels  

C. The cutting down of trees           D. Natural climate change

Antidepressant(抗忧郁)drugs such as Prozac were viewed in the early 1900's as wonder pills that would remove depressive blues for good. But in the past five years, growing scientific evidence has shown these drugs work for only a minority of people. And now a research journal says that these antidepressants can make many patients' depression worse. This alarming suggestion centres on the very chemical that is targeted by antidepressants-serotonin(血清素). Drugs such as Prozac are known as selective serotonin re-uptake inhibitors(or SSRIs). Their aim is to increase the level of this  “feel-good” chemical in the brain.

But the new research, published in the journal Frontiers In Evolutionary Psychology, points out that serotonin is like a chemical Swiss Army knife, performing a very wide range of jobs in the brain and body. And when we start changing serotonin levels purposely, it may cause a wide range of unwanted effects. These can include digestive problems and even early deaths in older people, according to the study's lead researcher Paul Andrews. “ We need to be much more cautious about use of these drugs,” says Andrews, an assistant professor of evolutionary psychology at McMaster University in Ontario, Canada.

Previous research has suggested that the drugs provide little benefit for most people with mild depression, and actively help only a few of the most severely depressed. Famous psychologist Irving Kirsch has found that for many patients, SSRIs are no more effective than a placebo pill. A research in 2010 on Danish children found a small, but significant, increase in the risk of heart problems among babies whose mothers had used SSRIs in early pregnancy. The key to understanding these side-effects is serotonin, says Andrews. Serotonin is also the reason why patients can often end up feeling still more depressed after they have finished a course of SSRI drugs. He argues that SSRI antidepressants disturb the brain, leaving the patient an even greater depression than before.

“After long use, when a patient stops taking SSRIs, the brain will lower its levels of serotonin production,” he says, adding that it also changes the way receptors in the brain respond to serotonin, making the brain less sensitive to the chemical. These changes are believed to be temporary, but studies indicate that the effects may continue for up to two years.

Most disturbingly of all, Andrews' review features three recent studies which, he says , show that elderly antidepressant users are more likely to die earlier than non-users, even after taking other important variables into account. One study, published in the British Medical Journal last year, found patients given SSRIs were more than 4 per cent more likely to die in the next year than those not on the drugs.

“Serotonin is an ancient chemical,” says Andrews. “It is regulating many different processes, and when you disturb these things, you can expect that it is going to cause some harm.”

Stafford Lightman, professor of medicine at the University of Bristol, and a leading UK expert in brain chemicals and hormones, says Andrews’ review highlights some important problems, yet it should also be taken with a pinch of salt. “This report is doing the opposite of what drug companies do,” he says. “Drug companies selectively present all the positives in their research, while this search selectively presents all the negatives that can be found. Nevertheless, Andrews' study is useful in that it is always worth pointing out that there is a downside to any medicine. ” Professor Lightman adds that there is still a great deal we don't know about SSRIs-not least what they actually do in our brains.

When it comes to understanding why the drugs work only for a limited part of patients, U.S.  scientists think they might now have the answer. They think that in many depressed patients, it’s not only the lack of feel-good serotonin causing their depression, but also a failure in the area of the brain that produces new cells throughout our lives. This area, the hippocampus, is also responsible for regulating mood and memory. Research suggests that in patients whose hippocampus has lost the ability to produce new cells, SSRIs do not bring any benefit.

1.According to paragraph 2, serotonin, like a chemical Swiss Army knife, can             .

A. make many patients' depression worse

B. cause a wide range of unwanted effects

C. affect human body and brain in various ways

D. provide little benefit for most depressed people

2.In Stafford Lightman's opinion,                     .

A. drug companies don't know the negative effect of antidepressants

B. Andrews focused on different things from the drug companies

C. scientists have found what SSRIs do in the brain

D. Andrews' research has no medical value

3.Which of the following is TRUE about SSRIs?

A. They are used to increase the “feel-good” medical in the brain.

B. They can work even when the hippocampus can't produce new cells.

C. They create a risk of heart problems in pregnant women.

D. They are responsible for controlling mood and memory.

4.What is the text mainly about?

A. The aim of drug companies

B. The function of SSRIs

C. The side-effects of antidepressants

D. The cause of depression

Smoking, which may be a pleasure for some people, is a series of discomfort for their fellows. Medical scientists have expressed their concern about effect of smoking on the health not only of those who smoke but also those who do not smoke. In fact, non-smokers who take in the air polluted by tobacco smoke suffer more than the smokers themselves. A great number of students are trying to persuade the university to forbid smoking in classrooms. Believe they are completely right in their aim. However, I think it more important to achieve this by calling on the smokers to use good judgment and to show concern for others. Smoking is not allowed in theaters, cinemas and in other public places. Therefore, smoking must be forbidden in our classroom. Although many people have passed away for having smoked a lot and we call on people to give up smoking, yet many more that are following will turn down what we say every day, above all, the young people smoke a lot more.

1. In the writer’s opinion, smoking does good to ________.

A. nobody B. some people C. smokers D. young people

2. The phrase “pass away” probably means ________.

3.According to the selection, which of the following is true?

A. Smokers suffer from the polluted air more than the non-smokers.

B. Non-smokers suffer from the polluted air more than the smokers.

  C. Non-smokers suffer as much from the polluted air as the smokers.
