Wash Your Clothes with a Cup of Water?
A washing machine that uses only a cup of water to carry a full wash, leaving clothes completely dry, has been developed by British inventors. Researchers say the technology, which uses less than 2 percent of the water and energy of a traditional machine, could save billions of liters of water each year.
The machine works by using thousands of plastic chips— each about half a centimeter in size—to absorb and remove dirt. Around 20 kilos of the chips are added to each load, along with a cup of water and detergent（洗涤剂）. During the washing cycle, the water is heated to help dissolve the dirt, which is then absorbed by the plastic chips. The inventors say the chips should be removed at the end of each wash, but can be used up to 100 times.
The technology, called Xeros, is already being compared to the Dyson bagless vacuum cleaner, which revolutionized the home cleaning industry when it was first introduced to the public in the mid-1990s.
If adopted by many homes across the UK, the machine could save billions of liters of water each year. According to the research, washing machine use has risen by 23 percent in the past 15 years, up from three times a week in 1990 to an average four times now. The average UK household uses most 21 liters of water daily on clothes washing. Nationally, this equals to approximately 455 million liters of water a day — enough to fill 145 Olympic-sized swimming pools.
Although the Xeros is now in the design and testing stage, the inventors say they are in talks with a commercial partner. The machine could be in the market as early as next year. Tests have produced quite astonishing results. “We’ve shown that it can remove all sorts of everyday stains including coffee and lipstick while using a tiny fraction of the water used by traditional washing machines,” said one of the inventors.
An expert said, “This is one of the most surprising and remarkable technologies I’ve had in recent years. Xeros has the ability to save billions of liters of water per year and, we believe, the potential to revolutionize the global laundry market.

An increase in students applying to study economics at university is being attributed to the global economic crisis awakening a public thirst for knowledge about how the financial system works.
Applications for degree courses beginning this autumn were up by 15% this January, according to UCAS, the Universities and Colleges Admissions Service. A spokesman for the Royal Economic Society said applications to do economics at A-level were also up.
Professor John Beath, the president of the society, and a leading lecturer at St Andrews University, said his first-year lectures—which are open to students from all departments—were drawing crowds of 400, rather than the usual 250.
“There are a large number of students who are not economics majors, who would like to learn something about it. One of the things I have done this year is to relate my teaching to contemporary events in a way that one hasn’t traditionally done.” He added.
University applications rose 7% last year. But there were rises above average in several subjects. Nursing saw a 15% jump, with people’s renewed interest in careers in the public sector, which are seen as more secure in economic crisis.
A recent study showed almost two thirds of parents believed schools should do more to teach pupils about financial matters, and almost half said their children had asked them what was going on, although a minority of parents felt they did not understand it themselves well enough to explain.
Zack Hocking, the head of Child Trust Funds, said: “It’s possible that one good thing to arise from the downturn will be a generation that’s financially wiser and better equipped to manage their money through times of economic uncertainty.”Professor John Beath’s lectures are .
| A．given in a traditional way |
| B．open to both students and their parents |
| C．connected with the present situation |
| D．warmly received by economics |
Incomes in the public sector are more attractive because of their .
| A．greater stability | B．higher pay |
| C．fewer applications | D．better reputation |
In the opinion of most parents .
| A．economics should be the focus of school teaching |
| B．more students should be admitted to universities |
| C．children should solve financial problems themselves |
| D．the teaching of financial matters should be strengthened |
According to Hocking, the global economic crisis might make the youngsters .
| A．have access to better equipment | B．wiser in money management |
| C．confident about their future careers | D．get jobs in Child Trust Funds |
What’s the main idea of the text?
| A．Universities have received more applications. |
| B．College students benefit a lot from economic uncertainty. |
| C．Economics is attracting an increasing numbers students. |
| D．Parents are concerned with children’s subject selection. |
When it comes to friends, I desire those who will share my happiness, who possess wings of their own and who will fly with me. I seek friends whose qualities illuminate （照亮） me and train me up for love. It is for these people that I reserve the glowing hours, too good not to share.
When I was in the eighth grade, I had a friend. We were shy and “too serious” about our studies when it was becoming fashionable with our classmates to learn acceptable social behaviors. We said little at school, but she would come to my house and we would sit down with pencils and paper, and one of us would say: “Let’s start with a train whistle today.” We would sit quietly together and write separate poems or stories that grew out of a train whistle. Then we would read them aloud. At the end of that school year, we, too, were changing into social creatures and the stories and poems stopped.
When I lived for a time in London, I had a friend. He was in despair and I was in despair. But our friendship was based on the idea in each of us that we would be sorry later if we did not explore this great city because we had felt bad at the time. We met every Sunday for five weeks and found many excellent things. We walked until our despairs disappeared and then we parted. We gave London to each other.
For almost four years I have had a remarkable friend whose imagination illuminates mine. We write long letters in which we often discover our strangest selves. Each of us appears, sometimes in a funny way, in the other’s dreams. She and I agree that, at certain times, we seem to be parts of the same mind. In my most interesting moments, I often think: “Yes, I must tell...” We have never met.
It is such comforting companions I wish to keep. One bright hour with their kind is worth more to me than the lifetime services of a psychologist, who will only fill up the healing silence necessary to those darkest moments in which I would rather be my own best friend. In the eighth grade, what the author did before developing proper social behavior was to .
| A．share poems and stories with her friend |
| B．go to her friend’s house regularly |
| C．become serious about her study |
| D．learn from her classmates at school |

| A．our unpleasant feeling about London disappeared |
| B．we were unwilling to tear ourselves away from London |
| C．our exploration of London was a memorable gift to both of us |
| D．we parted with each other in London |
According to Paragraph 4, the author and her friend .

| C．have similar personalities | D．dream of meeting each other |
In the darkest moments, the author would prefer to .
| A．seek professional help | B．break the silence |
| C．stay with her best friend | D．be left alone |

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 controversial forms.
In the fourth edition the main changes are as follows.
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 place, sentence adverbs, cleft sentences, prepositions, conjunctives, modal verbs, perfect tenses, infinitive constructions, the passive, purpose clauses and nouns.
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.

Look closely at ,your hands-are they clean? It doesn't matter how many times you was your hands. They're still crowded with microbes, which are also called "germs" or "bacteria". Microbes are everywhere. But don't worry-most microbes don't harm you. and many actually help you stay alive.
Now, scientists say the microbes that live on our hands could be used in a surprising way: fighting crime.
When police visit the scene of a crime, they often look for fingerprints to try to identifythe criminal. But according to a recent study, investigators could even use microbes to help break a criminal case.
Every person has his or her own set of microbes that live on their hands, according to scientists at,the University of:Colorado. That means the mix of different kinds of microbes on everybody's hand is unique-much like one's fingerprint.
The scientists wanted to know whether this microbe mix could be used as a new kind of fingerprint-especially in a crime scene where fingerprints might be hard to find. And policemen use forensics such as studying fingerprints to identify the criminal.
"Microbe fingerprints are harder to hide," said Noah Fierer, one of the scientists.
"You can't sterilize(为……杀菌) a surface just by wiping it off. "
His team compared the bacteria on the hands of 273 people with the bacteria found on each person's computer keyboard. For the study, the keyboards had been used only by the people who were being tested. The study showed that the mix of microbes from each per- son's hands matched the mix of microbes on that person's keyboard. The scientists were easily able to tell the 273 people apart-just by looking at their keyboards.
But there are a lot more than 273 criminals. Other scientists wonder whetherthe microbe fingerprint can really be that useful.
Fierer agrees that scientists have a lot more work to do before the microbe fingerprint will be a useful tool．According to the passage, microbes on people's hands_____
| A．do more harm than good | B．are easy to get rid of |
| C．are almost the same | D．might help find crimes |
The underlined word "forensics" in Paragraph 5 probably refers to________.
| A．the scientific test used by police |
| B．a new kind of fingerprint |
| C．a kind of bacteria'in people's hands |
| D．a kind of newly invented keyboard |
What did Fierer's team find through the study?
| A．They found the criminal among the 237 people. |
| B．They could tell who had used which computer. |
| C．Computer keyboards couldn't keep people's microbe fingerprints. |
| D．People's characters could be identified by the keyboards they used. |
We can learn from the passage that ______.
| A．your microbes may give you away |
| B．scientists will come to a clear conclusion soon |
| C．many scientists think microbe fingerprints useless |
| D．the microbe fingerprint has been used in many cases |
The main idea of the passage is about_____.
| A．the importance of fingerprints | B．how to clean our hands |
| C．the usefulness of microbes | D．different germs on our hands |
If you want to teach your children how to say sorry, you must be good at saying it yourself, especially to your own children. But how you say it can be quite tricky.
If you say to your children "I'm sorry I got angry with you, but...", what follows that "but" can make the apology ineffective:"I had a bad day" or "your noise was giving me a headache" leaves the person who has been injured feeling that he should be apologizing for his bad behavior in expecting an apology.
Another means by which peaple appear to apologize without actually doing so is to say "I'm sorry you're upset"; this suggests that you are somehow at fault for allowing yourself to get upset by what the other person has done.
Then there is the general, all-covering apology, which avoids the necessity of identifying a specific act that is particularly hurtful or insulting, and which the person who is apologizing should promise never to do again. Saying "I'm useless as a parent" does not commit a person to any specific improvement.
These pseudo-apologies(假道歉) are used by people who believe saying sorry shows weakness. Parents who wish to teach their children to apologize should see it as a sign of strength, and therefore not take these pseudo-apologies.
But even when presented with examples of real apology, childfen still need help to become aware of the complexities of saying sorry. A three-year-old might need help in un- derstanding that other children feel pain just as he does, and that hitting a playmate over the head with a heavy toy requires an apology. A six-year-old might need reminding that spoiling other children's expectations can require an apology. A 12-year-old might need to be shown that destroying the biscuit tin without asking permission is acceptable, but that
borrowing a parent's clothes without permission is not.If a mother adds "but" to an apology, ________.
| A．the child may find the apology easier to accept |
| B．the child may feel that he owes her an apology |
| C． she promises never to do it again |
| D．she does not realize that the child has been hurt |
According to the author, saying "I am sorry you are upset" most probably means “_______”
| A．You have good reason to get upset |
| B．I apologize for hurting your feelings |
| C．I am at fault for making you upset |
| D．I am aware you are upset, but I am not to blame |
It is not advisable to use the general, all-covering apology because _______.
| A． it is not clear and ineffective |
| B． it is hurtful and insulting |
| C． it may make the other person feel faulty |
| D．it gets one into the habit of making empty promises . |
We learn from the last paragraph that in teaching children to say sorry_______
| A．the complexities involved should be ignored |
| B．parents need to set them a good example |
| C．their ages should be taken into account |
| D．parents should be patient and tolerant |
It can be inferred from the passage that apologizing properly is________.
| A．a sign of social,progress |
| B．not as simple as it seems |
| C．not necessary among family members. |
| D．a social issue calling for immediate attention |
