What should you think about when trying to 
find your career? You are probably better at some school subjects than others. These may show strengths that you can use in your work. A boy who is good at mathematics can use that in an engineering career. A girl who spells well and likes English may be good at office work. So it is important to know the subjects you do well in at school. On the other hand, you may not have any especially strong subjects but your records show a general satisfactory standard. Although not all subjects can be used directly in a job, they may have indirect value. A knowledge of history is not required for most jobs but if history is one of your good subjects you will have learned to remember facts and details. This is an ability that can be useful in many jobs.
Your school may have taught you skills, such as typing or technical drawing, which you can use in your work. You may be good at
metalwork or cookery and look for a job where you can improve these skills. If you have had a part-time job on Saturdays or in the summer, think what you gained from it. If nothing else, you may have learned how to get to work on time, to follow instructions and to get on with older worker
s. You may have learned to give correct change in a shop, for example. Just as important, you may become interested in a particular industry or career you see from the inside in a part-time job.
Facing your weak points is also part of knowing yourself. You may be all thumbs when you handle tools; perhaps you are a poor speller or cannot add up a column of figures. It is better to face any weakness than to pretend they do not exist. Your school record, for instance, may not be too good, yet it is an important part of your background. You should not be apologetic(认错的) about it but instead recognize that you will have a chance of a fresh start at work. What is the passage mainly about?
| A．The importance of working hard at school. |
| B．Choosing a career according to one’s strengths. |

| A．should pay more attention to learning skills and developing abilities |
| B．will be regretful about his bad results |
| C．may also do well in his future work |
| D．should restart his study in school |
The underlined phrase “be all thumbs” (in Para 3) probably means “_______”.

| C．be not interested in certain things | D．be easily bored in doing things |
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.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 |

| D．They are responsible for controlling mood and memory. |

Preface to the fourth edition
A practical English Grammar is intended for intermediate(中级的) and post-intermediate students. We hope that more advanced learners and teachers will also find it useful.
The book is a comprehensive survey of structures and forms, written in clear modern English and illustrated with numerous examples. Areas of particular difficulty have been given special attention. Differences between conversational usage and strict grammatical forms are shown but the emphasis is on conversational forms.
1. Explanation and examples have been brought up to date.
2. There is now more information on countable and uncountable nouns, attributive and predicative adjectives, adverbs of places, sentence adverbs, cleft sentences, prepositions, conjunctives, modal verbs, perfect tenses, infinitive constructions, the passive, purpose clauses and nouns.
In the fourth edition the main changes are as follows.
3. Some material has been rearranged to make comparisons easier. For example, parts of chapters on can, may, must etc. are now grouped by functions; verbs of liking and preference have a chapter to themselves; suggestions and invitations have joined the chapter on commands, requests and advice.
4. The contents list now summaries every edition heading, and there is a new index containing many more entries references.
In this edition the sign “～” is frequently used to show a change of speaker in examples of dialogue. Note also that although the sign “＝”sometimes connects two words or expressions with the same meaning, it is often used more freely, e.g. to indicate a transformation from active to passive or direct to indirect speech.
We wish to thank all at Oxford University Press who have assisted in the preparation of the fourth edition. We would also like to thank Professor Egawa of Nihon University, Japan, Professor Rene Dirven of Duisburg University, West Germany and other colleagues for their friendly and helpful suggestions.

The common Chinese greeting of “Ni chi le ma?” may soon be replaced by a new greeting: “Have you cleaned your plate?”
Over the Spring Festival holiday there was a big effort to get people to curb their habit of ordering too much food in restaurants because a lot of that food ended up being wasted. Holiday eaters were urged to “clean their plates” and were asked to take leftover food home in “doggy bags.”
The impetus behind the campaign was the startling government statistic that over 200 billion yuan is spent every year on food that ends up in the garbage bin. And in the midst of all this waste, statistics show that 128 million people are living below the poverty line and going hungry.
The “clean your plate” campaign is part of a worldwide effort to stop precious food from being wasted. The United Nations estimates that $1trillion (yes, that’s a very big number) worth of food is wasted each year. Most of that is lost during food production and transportation, but a significant percentage is attributed to waste by consumers. The United Nations Environment Program (UNEP) has launched a campaign called “Think. Eat. Save.” to make people aware of the problem.
Chinese actress Fan Bingbing is an ambassador for UNEP and she encouraged people to upload pictures of their “clean plates” to show their support for the program. Thousands of people responded and demonstrated that they had a clear conscience to go along with their full stomachs.
Xi Jinping, the Chinese president, is also urging people to be less wasteful and he told Party members to cut back on extravagant holiday banquets and to be more careful when spending the people’s money.
For some, though, Xi Jinping’s and Fan Bingbing’s admonitions don’t go far enough. Yuan Longping, an agricultural scientist, caused a stir by saying that wasting food should be treated as a crime. (Jail time for leftover chicken feet!?)
If not a crime, wasting food is certainly a sin and it goes against what Xi Jinping calls, “the Chinese tradition of being diligent and thrifty.” Having a “clean plate” is just a traditional and responsible thing to do. Which statement is NOT TRUE according to the passage?
| A．Over 200 billion yuan is wasted every year on food around China. |
| B．It’s quite common for Chinese people to order more food than they need in restaurants. |
| C．It’s universally acknowledged that wasting food is a crime. |
| D．Fan did something to promote people’s awareness of saving food. |
The underlined word “admonition” is closest in meaning to “”.
| A．demonstration | B．indication | C．warning | D．criticism |
What’ the best title for the passage?
| A．Food is important. |
| B．Have you cleaned your plate? |
| C．Jail time for leftover chicken feet!? |
| D．Wasting food is a crime. |
It is 4 o’clock in the early morning. Everything but the computing room on the campus of the university appears as quiet and misty as the mysterious hell. In the computing room, 30 students with sleepy eyes, sit still at their desk, beating the dirty and worn keys. Staring at the colorful screen, they tap continuously for hours. For the other parts in the world, it might be in the middle of the night, nevertheless here time represents nothing. It is an entirely enclosed field. These young computer “hackers” are tracing a sort of stimulus (刺激), a drive so exciting and absorbing that it ignores nearly anything else in their lives and becomes the focus of their being. They are addicted (上瘾的) computer programmers. Some of these students have been glued to the console (电子设备的操纵台) for no less than twenty hours even with no break for meals or rest. Some have been sleeping on sofas and chairs in the computing room, trying to struggle for a few moments’ rest but hating to get too far away from their addicted machines.
It is not necessary for most of these students to be at the computing room in the middle of the night. What they are working belong to no assignments. They remain there because they desire to be — they can not resist the attraction of the computers.
Furthermore, they are in groups instead of being alone. There are hackers at computing rooms all over the country. In the unimaginable way, they focus on nothing but computer. They escape from schooling and live beyond friendship; they might have difficulty being employed, choosing to travel from one computing room to another. They may even give up personal health.
“There is one hacker in my memory. We actually had to lift him away from his chair to feed him and arrange him to rest and sleep. We truly worried about his health,” says a computing science professor at California University.
Professors of computer science are nowadays paying more attention to this hacker phenomenon and are on the watch for future hackers and more and more severe computer addicts. They believe firmly that hackers are not simply resulted from the close relationship with a machine. It is the result of social relationship with the attractive thinking machines, which are becoming nearly universal.

In a world with limited land, water and other natural resources, the harm from the traditional business model is on the rise. Actually, the past decades has seen more and more forests disappearing and globe becoming increasingly warm. People now realize that this unhealthy situation must be changed, and that we must be able to develop in sustainable (可持续的) ways. That means growth with low carbon or development of sustainable products. In other words, we should keep the earth healthy while using its supply of natural resources.
Today, sustainable development is a proper trend in many countries. According to a recent study, the global market for low carbon energy will become three times bigger over the next decades. China, for example, has set its mind on leading that market, hoping to seize chances in the new round of the global energy revolution. It is now trying hard to make full use of wind and solar energy, and is spending a huge amount of money making electric cars and high speed trains. In addition, we are also seeing great growth in the global markets for sustainable products such as palm oil， which is produced without cutting down valuable rainforest. In recent years the markets for sustainable products have grown by more than 50%.
Governments can fully develop the potential of these new markets. First, they can set high targets for reducing carbon emission (排放) and targets for saving and reusing energy. Besides, stronger arrangement of public resources like forests can also help to speed up the development. Finally, governments can avoid the huge expenses that are taking us in the wrong direction, and redirecting some of those expenses can accelerate (加速) the change from traditional model to a sustainable one.
The major challenge of this century is to find ways to meet the needs of growing population within the limits of this single planet. That is no small task, but it offers abundant new chances for sustainable product industries.
