In 2004，the World Health Organization，WHO，warned of a possible outbreak of another serious disease which may be even more deadly than SARS．The WHO believes that it is likely that bird flu will spread to human beings in the next few years．If it does，up to seven millions people could die from the disease．

Diseases like bird flu are caused by viruses，that is，tiny things which change and become more dangerous over time．When a new type of a common virus changes，it may be able to get past the body’s immune(免疫的)system．If that happens，humans are in great danger until a cure or treatment becomes available．

There have always been viruses and people always get sick，of course，but as we saw with SARS，the situation is more difficult today．People travel more than ever before，which means that disease can spread quickly and across large areas——in fact the whole world．

Scientists are already working on drugs that will prevent or limit the effect of a new virus，but the process takes time．It is just as important to make sure that countries，especially poor countries，are prepared to deal with the disease. New disease usually affect poor areas the most，so we must help develop health care in all countries．

The situation is more serious today because           ．

A．people travel more                                      B．people don’t eat healthy food

C．there aren’t enough hospitals                        D．scientists can’t find a cure

From this passage we know           ．

A．bird flu will surely spread to human beings in the next few years．

B．a virus changes and become less dangerous over time．

C．SARS is 1ikely to come again in some years．

D．poor areas usually suffers more from new diseases than rich areas．

The possible title of this passage is

A．The Work of WHO

B．Scientists Are Working Hard on Drugs for Diseases

C．What Is a Virus

D．Virus Changes and Causes New Diseases Over Time

A "lost tribe" that reached America from Australia may have been the first Native Americans, according to a new theory.

If proved by DNA evidence, the theory will break long established beliefs about the southerly migration of people who entered America across the Bering Strait, found it empty and occupied it.

On this theory rests the belief of Native Americans to have been the first true Americans. They would be classified to the ranks of escapee, beaten to the New World by Aboriginals (土著人) in boats.

To a European, this may seem like an academic argument, but to Americans it is a philosophical question about identity (身份), Silvia Gonzales, of Liverpool University said .

Her claims are based on skeletons found in the California Peninsula of Mexico that have skulls (头骨) quite unlike the broad Mongolian features of Native Americans. These narrow-skulled people have more in common with southern Asians, Aboriginal Australians and people of the South Pacific Region.

The bones, stored at the National Museum of Anthropology (人类学) in Mexico City, have been carbon-dated and one is 12,700 years old, which places it several thousand years before the arrival of people from the North. "We think there were several migration waves into the Americas at different times by different human groups," Dr. Gonzales said． "The timing, route and point of origin of the first colonization of the Americas remains a most contentious topic in human evolution."

But comparisons based on skull shape are not considered conclusive by anthropologists, so a team of Mexican and British scientists, backed by the Natural Environment Research Council, has also attempted to take out DNA from the bones. Dr. Gonzales declined yesterday to say exactly what the results were, as they need to be checked, but indicated that they were consistent（一致） with an Australian origin.

It is generally considered that the first Native Americans came from _____.

       A．North Asia      B．Australia   C．South Pacific   D．South Asia

The skeletons found in the California Peninsula of Mexico have _____.

       A．the broad skull shape     

       B．the narrow skull shape

The underlined “contentious” is similar in meaning to “_____”.

       A．likely to cause great interest    B．difficult to solve

       C．well-known to all           D． likely to cause argument

Which of the following statements is true according to the text?

       A．Research on skulls can draw an exact conclusion.

       B．DNA tests have proved the fact that the first Native Americans came from Australian.

       C．Scientists are still not sure about the origin of the Native Americans.

       D．People began to enter America across the Bering Strait about 12,700 years ago.

A university graduate described as a “respectable and intelligent” woman is seeking professional help after being convicted of （证明有……罪）shoplifting for the second time in six months.

       Ana Luz, recently studying for her PhD, has been told she could end up behind bars unless she can control the desire to steal from shops.

       Luz ,who lives with her partner in Fitzwilliam Road, Cambridge, admitted stealing clothes worth ￡9.95 from John Lewis in Oxford Street, London, on March 9.

       Phillip Lemoyne, prosecuting（起诉）,said Luz selected some clothes from a display and took them to the ladies’ toilet in the store .When she came out again she was wearing one of the skirts she had selected, having taken off the anti-theft security alarms（防盗警报装置）.

       She was stopped and caught after leaving the store without paying, Mr. Lemoyne said.

       He added that she was upset on her arrest and apologized for her actions.

       Luz, 28, was said to have been convicted of shoplifting by Cambridge judges last October, but Morag Duff, defending, said she had never been in trouble with the police before that.

       “She is ashamed and embarrassed but doesn’t really have any explanation why she did this,” Miss Duff said. “She didn’t intend to steal when she went into the store. She is at a loss to explain it. She is otherwise a very respectable and intelligent young lady. She went to her doctor and asked for advice because she wants to know if there is anything in particular that caused her to do this.”

       Judge David Azan fined Luz ￡ 50,  and warned : “You’ve got a criminal record .If you carry on like this ,you will end up in prison ,which will ruin your bright future you may have.”

       Luz achieved a degree in design at university in her native Spain, went on to a famous university in Berlin, Germany for her master’s degree and is now studying for a PhD at Cambridge University, UK.

C. the university graduate will be put in prison if she steals in shops once more

D. Phillip Lemoyne is the “respectable and intelligent” woman’s defense lawyer

From a young age, it was my dream to go to Africa and work with animals. Everybody laughed at me, but my mother, Vanne, told me never to give up, and that I could always find a way.

So, when I was 23, after saving up my earnings from working as a waitress, I went to wild, untamed (野性的) Africa and began my work. In 1960 I went to the Gombe Stream Chimpanzee Reserve. At that time, we knew nothing of the behavior or social structure of chimps (黑猩猩), and I was to go there and see what I could find out. Usually, when you wake up, you leave your dreams behind you, but I found myself waking up to my dream.

As the British government wouldn’t let me go without older women’s company, my amazing mother came with me and stayed for four months. We shared a second-hand army tent, and we used the stream for fresh water and washing. We could swim in the lake, although there were crocodiles.

It was beautiful there, although both my mother and I nearly died of malaria (疟疾). I was scared I wouldn’t be able to do what I had set out to, because, at first, the chimps ran away from me in fear. I spent my days watching, listening, tracking and in the evenings writing up my notes.

For my mother, who stayed back at the camp, it must have been terrifying, and very lonely. There were snakes and spiders, as well as an old leopard who would come by. But she had an amazing way with people, and would hand out medicines to the fishermen, who saw her as a witch doctor.

In my fifth month there, I finally saw one of the chimps, which I called David Greybeard, stripping (剥光) straw to “fish” for termites (白蚁). It proved that man wasn’t the only toolmaker, and that everything had to be redefined.
