David Ho is one of the most famous scientists in the world because of his research on fighting AIDS.
He was born in 1952 in Taiwan, China. He was given the name He Dayi. Dayi means “Great One” in Chinese. His family moved to the United States when he was 12 years old.
David was a smart student and he first studied Physics. He quickly realized that he was interested in life science, so he went to Harward Medical School. It was there that he saw people who had AIDS. In the early 1980s, AIDS was almost unknown and Ho made up his mind to study this mysterious (難解的) killer disease.
Ho discovered that the HIV virus(病毒) could survive in a healthy person’s body for years. He realized that the earlier a person with HIV is treated, the longer he will live.
His work is very important. With the help of his research, combinations of drugs (合成藥) have been developed and the lives of thousands of people have been saved. The whole world was grateful to him. Because of his work, he was named Time magazine’s Man of the Year in 1996.
At 37, he was appointed (任命) Director of the Aaron Diamond AIDS Research Centre in New York. In recent years, he has been doing research on making a vaccine (疫苗) against AIDS. If Ho finds a vaccine for AIDS, he will become an international hero.

On May 23, Shenzhen introduced new rules in order to prevent the “Chinese style of crossing the road”. “Chinese people cross roads without thinking about traffic lights, so long as they are part of a group of people,” said a post on Sina Weibo.
A CCTV news program showed that in only an hour, more than 600 people jumped red lights when crossing a road in Shijiazhuang, Hebei.
Many people say that they jaywalk(亂穿馬路) because the red light lasts too long. Such an opinion is supported by a research(研究)group at Tongji University. The team did research on people’s waiting times at different road crossings for three years. They found that Chinese people would wait for 70 to 90 seconds before they lost their patience. “People are likely to ignore(忽視) the light when the waiting time is longer than they can bear,” said Ni Ying, a member of the research team.
However, a survey on Sina Weibo suggested that people jaywalk mainly because they ignore rules. “I always obey traffic rules. Time is important but safety should come first,” someone wrote on his Weibo.
Many countries give out punishments to jaywalkers. In Singapore, the maximum can be three months in prison(監(jiān)獄). Some Chinese cities have started taking some actions, too. For example, the first three people in a jaywalking group will be fined 50 yuan in Shijiazhuang.
But calling on people to obey rules is more important. To completely solve the problem, everyone should understand the importance of obeying the traffic rules.
1.The phrase “the team” in Paragraph 3 refers to ________.
A. A CCTV news program.
B. A research group at Tongji University.
C. A post on Sina Weibo.
D. A daily newspaper.
2.How long will Chinese people wait for to cross the road before they lose patience?
A. About five minutes.
B. Less than one minute.
C. Less than one and a half minutes.
D. More than ten minutes.
3.Why do people jaywalk according to the survey on Sina Weibo?
A. Because people don’t pay much attention to rules.
B. Because there are too many people on the road.
C. Because the red light lasts too long.
D. Because people have less patience.
4.To solve the problem of jaywalking, the writer suggests that we should __________.
A. punish the jaywalkers
B. reduce the time of red lights
C. ignore the traffic rules
D. call on people to obey the traffic rules
