It happened one morning 20 years ago. A British scientist Alec Jeffrey came across DNA fingerprinting: He identified the patterns of genetic material that are unique to almost every individual. His discovery changed everything from the way we do criminal investigations to the way we decide family law. But the professor of genetics at the University of Leicester, UK, is still surprised, and a bit worried, by the power of the technology he released upon the world.
The patterns within DNA are unique to each individual, except identical twins, who share the same pattern. The ability to identify these patterns has been used to convict(证明…有罪) murderers and to clear people who are wrongly accused. It is also used to identify the victims of war and settle disputes over who is the father of a child.
Jeffrey said he and his colleagues made the discovery by accident while tracking genetic
variations(变异). But, within six months of the discovery, genetic fingerprinting had been used in an immigration case, to prove that an African boy really was his parents’ son.·In 1986, it was used for the first time in a British criminal case: It cleared one suspect after being accused of two murders and helped convict another man.
DNA testing is now very common. In Britain, a national criminal database established in 1995 now contains 2.5 million DNA samples. The U.S. and Canada are developing similar systems. But there are fears about the stored DNA samples and how they could be used to harm a person’s privacy. That includes a person’s medical history, racial origin or psychological profile. “There is the long-term risk that people can get into these samples and start getting additional information about a person’s paternity(父子关系) or risk of disease,” Jeffrey said.
DNA testing is not an unfailing proof of identity. Still, it is considered a reasonably reliable system for determining the things it is used for. Jeffrey estimates the probability of two individuals’ DNA profiles matching in the most commonly used tests at one in a billion.

One of the world's richest men has taken a close interest in one of man’s most basic functions: visiting the toilet.Bill Gates’s charitable organization, the Bill and Melinda Gates Foundation, is looking for inventors to design the loo of the future, which, they hope, would improve sanitation for millions of people around the world.
So, what's wrong with the traditional flush toilet? Firstly, it wastes a huge amount of potential drinking water.Secondly, they are more likely to cause pollution.This is a real problem in many areas of the developing world, where, according to United Nations estimates, unsafe sanitation causes half of all hospitalizations.Younger people are particularly at risk.Illnesses which cause diarrhea are responsible for the deaths of about 1.5 million children a year.Finally, standard lavatories simply aren’t practical in remote areas.
The challenge set by Bill Gates was to come up with a latrine which works without running water, electricity or aseptic tank(化粪池).It also needed to operate for less than 5 cents.28 designs were displayed at the recent Reinvent the Toilet Fair in Seattle, USA.Among them was one which turned human waste into electricity using microwaves, another which converted human waste into charcoal, and yet another which used urine for flushing.
But the winner was a solar-powered design which generated hydrogen gas and electricity.The team from the California Institute of Technology(CIT)picked up a prize of $ 100,000.
But clearly Bill Gates doesn’t feel he’s flushing money down the toilet.After the Seattle event he said, “We, couldn’t be happier with the response we’ve gotten,” Gates has even pledged $370m more to the future toilet project.They hope to field test more prototypes over the next three years.
【小题1】Why is Bill Gates paying people to invent new toilets?

A.Because he wants to test people’s sense of creativity.
B.Because he wants to improve sanitation for many people.
C.Because he thinks the traditional ones are out of fashion.
D.Because he can’t design this kind of things himself.
【小题2】Which of the following is NOT a problem with the traditional flush toilet?
A.They waste too much water.
B.They might cause diseases.
C.They are not always practical.
D.They are too complicated to use.
【小题3】The underlined word “latrine” in the third paragraph might have similar meanings to the word “__ ”n the text.
A.LooB.sanitationC.diarrheaD.prototype
【小题4】The team from CIT won the prize because their design        .
A.can change human waste into electricity
B.can turn human waste into charcoal
C.can produce power with solar energy
D.can use urine for flushing
【小题5】If someone “flush money down the toilet”, they are       .
A.showing off their wealth
B.being angry with their work onditions
C.wasting money for nothing
D.expressing their great determination

It is naturally impossible for a well educated, intellectual(懂道理的),or brave man to make money-the chief of his thoughts; it is naturally impossible for him to make his dinner—the necessary object of him. All healthy—minded people like their dinner, but their dinner is not the main object of their lives. So all healthy—minded people like making money—but the main object of their lives is not money; it is something more important than money.
A good soldier for instance, mainly wished to do his fighting well. He is glad for his pay—very properly so, and justly complains when you keep him ten months without it; still his main aim of his life is to win battles, not to be paid for winning them.
As for doctors, they like fees, no doubt — ought to like them; yet if they are brave and well educated, the entire object(目标) of their lives is not fees. They, on the whole, wishes to cure me sick, and—they are good doctors, and the choices is fairly put to them—would rather cure their patients and lose their fees than kill him and get it. And so with all other brave and rightly trained men—their work is first, their fees second, very important always, but still second. 
64. The text is mainly about ____.
A. money is not everything but no money is nothing
B. work is first but money is also important
C. work is the chief opinion of the good people’s lives
D. People like less work but more money
65. According to the text, it is ____ that a good solider will run away when a drowning man needs help but there is no money.
A. impossible        B. possible      C. clever           D. foolish  
66. The underlined word “it” in the last paragraph means ____
A. their patient       B. their work    C. the object of lives  D. their money
67. If you are middle school teacher described in the text, what will you do if you are not paid for six months?
A. To quarrel with the headmaster
B. To go on teaching in this school
C. To give up the teaching in this school and find a teaching job in another school
D. To go on teaching after getting paid

It is have xxxxxx that clothing manufacturcrs(生产商)follow certa a untharm standards far yarious featurce(特征)of clothes. What seerns strange, however. Is that the xxxxxx adopted for women is the opposite of the one for men. Take a look at the way your clodns buntm. Men’s clothes tend to button from the right, and women’s form the left. Lonsidering most of the world’s popalation—men and women—are right-handnd, the men’s standard would apper inake more sense for women. Xxxxx why do women’s clethes bution from the left?
Histov mally coms to matter here. Buttons finst appcaned only on the lothes or the rich in the 17th camary. When rich women were dressed by servents. For the mostly right-hand-d servants, having women’s shirts button from the left would be easier. On the other hand, having men’s shirt button from the right made secse.too. Most men dressed themselves, and a swont drawn from the lelt with the right hand would be lese likely to get catght in the sairt.
Tady women are seldom dressed by scryants. Hat tuaoning from the lefts still the standard for them. Is it intcesting? Actually, a standoont, once set, resists change. At a time when all women’s shirts buttoned from the left, it would have been risky for any sigle manufactura is offer women’s shirts that battoned from the right. After all, women had grown so used to shirts whirt unored from the left and would have to devclop new habits and skills to switch. Benides, come women might have found it socially awkward to appear in public wearing shirts that buttoned from the right, since anyone who rociced that would believe they were wearing men’s shirts.
64.What is surprising about the standard of the clothing industry?
A.It has been followed by the industry for over 400 years.
B.It is different for men’s clothing and women’s.
C.It works better with men than with women.

A.They tended to wear clothes without bottons.
B.They were interested in historical matters.
C.They were mostly dressed by servants.
D.They drew their swords from the left.
66.Women’s clothes still button from the left today because______.
A.abouting men’s style is improper for women
B.manufacturers should follow standards
