試題分析：句意：有許多人依舊在公共場合吸煙，這一事實(shí)表明我們也許需要搞一次全國性的活動來提高人們對于吸煙危害性的認(rèn)識。the fact后跟同位語從句，設(shè)空處為主句的謂語動詞，故排除D項；由題干中的smoke和may等可知語境指現(xiàn)在的情況，故排除C項。本句主語為the fact，且本句陳述的是一個事實(shí)，故謂語動詞應(yīng)采用第三人稱單數(shù)形式，故選B。

考點(diǎn)：考查時態(tài)和主謂一致

People born in winter are more likely to suffer mental health disorders, according to a recent study carried out by researchers at Vanderbilt University in Tennessee.

Researchers raised baby mice from birth to weaning (斷奶) in either “summer” light cycles of 16 hours of light and 8 hours of dark or “winter” cycles of 8 hours of light and 16 hours of dark. A third group experienced 12 hours of light and 12 hours of dark a day.

Then half the winter mice stayed in a winter cycle, while half switched to a summer schedule. The summer mice were similarly split. The mice raised in equal periods of light and dark were split into three groups, one of which stayed on the 12?hour schedule, one of which joined the winter group, and one of which joined the summer group.

After 28 days, it turns out the summer?born mice behaved the same whether they stayed on the summer cycle or switched to winter. But among the winter?born mice, those stayed in winter kept their previous schedule, while those that switched to summer stayed active for an extra hour and a half, which indicates that mice born and weaned in a winter light cycle showed dramatic disruptions in their biological clocks.

The finding is the first of its kind in mammals, and it could explain why people born in winter are at higher risk for mental health disorders including bipolar depression, schizophrenia and seasonal affective disorder.

“We know that the biological clock regulates mood in humans，”said study researcher McMahon. “If the mechanism (機(jī)制) similar to the one that we found in mice operates in humans, then it could not only have an effect on a number of behavioral disorders, but also have a more general effect on personality.”

1.How many groups of mice are there finally in all in the experiment?

A. Four.B. Five.C. Six. D. Seven.

2.What's the main idea of the text?

A. The biological clock regulates mood in humans.

B. People born in winter are at higher risk for physical health disorders.

C. Being born in winter has a negative effect on people's mental health.

D. The length of light will influence the behavior of the mice.

3.The underlined word “split”(Paragraph 3) can be replaced by ________.

A. endedB. torn C. hitD. divided

4.Who is the appropriate reader of the passage?

A. A job?hunter. B. A student in the university.

C. A newly?married couple. D. An experienced dentist.

I am wearing a small red ribbon this morning to remind myself and others around me that today is World AIDS Day.

The red ribbon, an international symbol of AIDS awareness, is gaining increasing public recognition as more Chinese, from top leaders to movie stars, wear it today.

Gone were the days when the topic of HIV/AIDS was a public and media taboo(禁忌). Over the past few years, we have watched, read and heard many stories from doctors, volunteers and public health officials at the forefront of HIV/AIDS prevention and treatment.

Quite a few people with HIV/AIDS have come forward to share their experiences on TV or in the media.

The local and central governments have become more forthcoming (be helpful) with their new prevention and treatment programmes, and financial input. The latter rose from less than 1 million yuan (US$ 121,000) in 1986 to a pledge of 800 million yuan (US$98.8 million) in the year of 2006.

The change from silence to public and media campaigns with official promises has been remarkable, especially since China battled through the SARS crisis.

But have we got a full understanding on HIV/AIDS? What do we know about the extent of HIV/AIDS in China?

The figures, ranging from confirmed cases to estimates, remain debated. After all, no more than a year has passed since the policy of free medical tests was make public. Unknown numbers from the high-risk groups drug addicts and people working in sex- related place as well as farmers who once sold blood could still be reluctant to come forward.

1.What does the red ribbon stand for?

A. AIDS awareness B. World AIDS Day

C. AIDS D. AIDS prevention and treatment

2.Which of the following is Not true according to the text?

A. The topic of HIV/AIDS was a public and media taboo in the past.

C. Now a lot of people with HIV/AIDS have come forward to share their experiences on TV.

D. The writer wears a small red ribbon because today is World AIDS Day.

3.In paragraph 5 “The latter” refers to ____________________.

A. new prevention programmes B. financial input

C. new treatment programmes D. the central governments

4.What is the best title of the passage?

A. The Red Ribbon B. Help people with AIDS

C. About AIDS D. Always keep red ribbon in sight
