Most mornings, the line begins to form at dawn: scores of silent women with babies on their backs, buckets balanced on their heads, and in each hand a brightblue plastic jug. On good days, they will wait less than an hour before a water tanker goes across the dirt path that serves as a road in Kesum Purbahari, a slum on the southern edge of New Delhi. On bad days, when there is no electricity for the pumps, the tankers don't come at all. “That water kills people，” a young mother named Shoba said one recent Saturday morning, pointing to a row of pails filled with thick, caramel (焦糖)colored liquid. “Whoever drinks it will die.” The water was from a pipe shared by thousands of people in the poor neibourhood. Women often use it to wash clothes and bathe their children, but nobody is desperate enough to drink it.
There is no standard for how much water a person needs each day, but experts usually put the minimum at fifty litres. The government of India promises (but rarely provides) forty. Most people drink two or three litres—less than it takes to wash a toilet. The rest is typically used for cooking and bathing. Americans consume between four hundred and six hundred litres of water each day, more than any other people on earth. Most Europeans use less than half that. The women of Kesum Purbahari each hoped to drag away a hundred litres that day—two or three buckets' worth. Shoba has a husband and five children, and that much water doesn't go far in a family of seven, particularly when the temperature reaches a hundred and ten degrees before noon. She often makes up the difference with bottled water, which costs more than water delivered any other way. Sometimes she just buys milk; it's cheaper. Like the poorest people everywhere, the people of New Delhi's slums spend a far greater percentage of their incomes on water than anyone lucky enough to live in a house connected to a system of pipes.The underlined word “slum” most likely means________.
| A．a village |
| B．a small town |
| C．an area of a town with badlybuilt, overcrowded buildings |
| D．the part of a town that lacks water badly |
Sometimes the water tanker doesn't come because________.

A person needs at least________litres of water a day.
| A．a hundred | B．four hundred |
| C．forty | D．fifty |
Which of the following statements is WRONG?
| A．A hundred litres of water a day is enough for Shoba's family. |

The world is filled with smart, talented, educated and gifted people．We meet them every day A few days ago, my car was not running well．I pulled it in to a garage and the young mechanic had it fixed in just a few minutes．He knew what was wrong by simply listening to the engine．I was amazed．The sad truth is that great talent is not enough．
I am constantly shocked at how little talented people earn. I heard the other day that less than 5 percent of Americans earn more than $100,000 a year. A business consultant who specializes in1 the medical trade was telling me how many doctors and dentists struggle financially. It was this business consultant who gave me the phrase, “They are one skill away from great wealth．”
There is an old saying that goes, "Job means 'just over broke（破产）’"．And unfortunately, I would say that the saying applies to millions of people．Because schools do not think financial intelligence is intelligence, most workers "live within their means"．They work and they pay the bills．Instead I recommend to young people to seek work for what they will learn, more than what they will earn．
When I ask the classes I teach, “How many of you can cook a better hamburger than McDonald's?” almost all the students raise their hands. I then ask, “So if most of you can cook a better hamburger, how come McDonald's makes more money than you?” The answer is obvious: McDonald's is excellent at business systems. The world is filled with talented poor people. They focus on perfecting their skills at building a better hamburger rather than the skills of selling and delivering the hamburger.The author mentions the mechanic in the first paragraph to show that．
| A．he is just one of the talented people |
| B．he is ready to help others |
| C．he has a sharp sense of hearing |
| D．he knows little about car repairing |
The underlined part in the third paragraph can be best replaced by____．
| A．spend more than they can afford |
| B．do in their own way |
| C．1ive in their own circle |
| D．1ive within what they earn |
Why do talented people earn so little according to the author?
| A．They don’t work hard enough |
| B．They lack financial intelligence． |
| C．They don't make full use of their talents |
| D．They have no specialized skills． |
The main purpose of the author is to tell us____．
| A．how young people can find a satisfactory job |
| B．What schools should teach about finance |
| C．why so many talented people are poor |
| D．how McDonald's makes much money |
Detective Keeling took his client — a good-looking lady into the back yard of the store together. The lady opened a door in the wall and they entered the small room behind the store. They crossed the room to a locked door.
M r. Keeling took some special keys from his pocket. Moments later, one of the keys unlocked the door. The lady went into the store. She said she would hide under the table to keep watch on her husband. Mr. Keeling did not follow her.
The detective went quickly to the policeman’s house. Then the two men hurried to the jewellery store. They looked through the window. The policeman was surprised. He spoke to Mr. Keeling. “I don’t understand. You told me, ‘Robbins took a young woman to a restaurant.’ Where is she?”
“There she is !” said Mr. Keeling. He pointed through the window.
“Do you know the lady with Robbins?” asked the policeman.
“That’s his secret friend,” said Mr. Keeling.
“No! You’re wrong! That’s Robbins’ wife,” said the policeman. “I’ve known her for fifteen years.”
“What ?” the detective shouted. His face became pale. “Who is under the table in the store?”
He started to kick the door of the jewellery store.
Mr. Robbins came to the door and opened it. The policeman and the detective ran into the store.
“Look under that table!” shouted the detective. “Be quick!”
The policeman lifted the cloth and put his arm under the table. He pulled out a black dress, a black veil and a woman’s wig(假发).
“Is this young lady your wife?” Mr. Keeling asked the jeweler. He pointed at the woman.
“Yes! She is my wife !” said Mr. Robbins angrily. “Why did you kick my door? Why are those clothes under my table?”
“Please check all the jewellery in your store, Mr. Robbins,” the policeman said. “Is anything missing?”
Some diamond rings and some expensive necklaces were missing. The missing jewellery was worth ＄800.
Later that night, Mr. Keeling was sitting in his office. He was looking through a big book of photographs. They were photographs of criminals. The policeman had brought the book to the detective’s office. Suddenly, Mr. Keeling stopped turning the pages. He looked at a picture of a handsome young man with a familiar face.

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 |
| C．affect human body and brain in various ways |

| 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. |

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. |
