A recent study led by researchers from the National University of Singapore (NUS) has found a clear link between the color of a taxi and its accident rate. An analysis of 36 months of detailed taxi, driver and accident data from two fleets of yellow and blue taxis in Singapore suggested that yellow taxis have fewer accidents than blue taxis. The higher visibility (能见度） of yellow makes it less difficult for drivers to avoid getting into accidents with yellow taxis, leading to a lower accident rate.

The study was led by Prof Ho. To test whether there was a relationship between the color of a taxi and the number of accidents the taxi had, the research team analysed data collected by the largest taxi company in Singapore. The researchers found that yellow taxis have about 6. 1 fewer accidents per 1,000 taxis per month.

They also studied the economic effect of changing the color of the entire fleet of taxis to yellow. The Singapore taxi company involved in the study owns about 16,700 taxis in a ratio (比例) of one yellow to three blue taxis. If a commercial decision is made to switch from blue to yellow taxis, 76. 6 fewer accidents will occur per month or 917 fewer accidents per year.

Assuming an average repair cost of $1,000 per car and a downtime of six days, the color of all taxis to yellow could produce an annual saving of $2 million.

“We are eager to continue to validate (证实) the findings of our study by looking at the use of yellow in other types of public transport, such as school buses. For example, we hope to compare the accident rates of yellow school buses against those of other colors to find out if yellow is indeed a safer color for school buses. Besides, we’ re also interested to look at private-hire vehicles and do a comparison of the accident rates of vehicles that are of different colors explained Prof Ho.

1.Why do yellow taxis result in fewer accidents?

A. Because yellow signals a warning of danger.

B. Because yellow can be seen more easily.

C. Because drivers tend to he more careful in yellow taxis.

D. Because people act more quickly in yellow surroundings.

2.What’ s Prof Ho’s study based on?

A. Physical risks taxi passengers experience.

B. The economic effect of changing taxi color.

C. Personal reports from taxi drivers worldwide.

D. Data from Singapore's largest taxi company.

3.What do Prof Ho’s words in the last paragraph suggest?

A. School buses should be painted yellow.

B. Their findings are worth popularizing.

C. Their study will be furthered.

D. Yellow should be widely used in public transport,

4.What can be the best title for the text?

A. Safer to ride in yellow taxis B. Caution: yellow taxis ahead

Football is a popular sport. More than a million kids play on high school teams, but football can be a hazard. The National Football League(NFL) has acknowledged that almost 30 percent of its players will eventually suffer from brain-related diseases. That’s a lot.

A recent study involving 40 former NFL players showed that those who started playing football before age 12 did worse on thinking tests than players who started after age 12. By the way, all the tested players scored below average for their age and education. Concerns about the effects of constant hits to the head have caused some medical experts on brain injuries, such as Robert Cantu of Boston University, to recommend that kids not play football before age 14.

I don’t think football is all bad. It helps kids learn teamwork, discipline and how to get into better physical condition. But now that we know that the sport might be dangerous, it’s time to make some changes in the youth and high school football.

First, seasons should be shorter. The high school regular season should not be more than nine games. Second, kids should not play tackle(擒抱) football too soon. As Cantu points out, “By age fourteen, our necks are strong and our overall body strength is sufficient to keep the head steady when we slam at the line of scrimmage(争球).” Personally speaking, I don’t think kids should sit on the couch until they are 14. But they can play flag football and other gentler sports. If you think age 14 is too late to become a good football player, remember that four-time Super Bowl winner Tom Brady started playing football at that age.

1.What does the underline word “hazard” mean?

A. difficulty. B. danger.

C. punishment. D. pain.

2.Why did the former NFL players perform badly in tests?

A. Their heads were hit frequently.

B. They had some mental disorders.

C. They didn’t take the tests seriously.

D. They received little school education.

3.What does the author advise for kids under 14?

A. They watch football games. B. They play safer games.

C. Football be forbidden for them. D. They play 10 games a season.

4.What is the purpose of the text?

A. To entertain. B. To advertise.

C. To instruct. D. To warn.

Do you hate your job? As far as I know, many young people liked complaining about their jobs. When my uncle started working about five years ago, he couldn’t stop complain about his work every time he got back from work. He considered his work simple and bored as he just needed to type works by famous writers. Therefore, as time went by, he found his work real helpful. When he was typing the works, he also read it. He learned lot from the works by famous writers and about two years later, his writing was greatly improved. He had his first books published last year and now he’s working for his second book.

The teachers are preparing their classrooms for the start of classes. As their principal, I was energized by their enthusiasm. Everywhere I went, I asked the same question, “How are you doing?” And everywhere I went, I received the same answer, “just fine.”

There was only one person whom I didn’t quite believe. It was her first year of teaching. Her classroom was inviting. She seemed well-prepared. On the outside everything seemed just fine, but there was something in her eyes that mad me ask that question again and again.

Then came Wednesday. “How are you doing?” I asked. “Mr. Boyce, I think I’m going to make it,” she said. The office was full of teachers and noise, but the voices became quiet as the young teacher continued.

“Monday night, after our open house (开放参观日)，I just didn’t think I could do it. There were so many parents and children, and I felt under great pressure. When I told my family I didn’t think I could do it , they said I had to try.

“The next morning school started. I thought I was ready, but there were so many of them and their needs were so different. I just didn’t know how I could manage.

“I said to my parents if I had fewer kids I could handle it. So they asked me which children I would get rid of. But I couldn’t decide. I’d only had them for one day, but I couldn’t think of a single child I could do without. They’re mine. I can’t do without any of them. I don’t know how, but I’m just going to do the best I can and I really think I’m going to make it. “

There wasn’t a dry eye in the office when I replied, “I think you are, too.”

In my profession as an educator and health care provider, I have worked with numerous children infected with the virus that causes AIDS. The relationships that I have had with these special kids have been gifts in my life. They have taught me so many things, but I have especially learned that great courage can be found in the smallest of packages.

Tyler was born infected with HIV and from the very beginning of his life, he was dependent on medications to survive. When he was five, he had a tube surgically inserted in a vein in his chest. This tube was connected to a pump, which he carried in a small backpack on his back. Medications were prepared inside this pump and were continuously supplied through this tube to his bloodstream. At times, he also needed supplemented (补充的)oxygen to support his breathing.

Tyler wasn’t willing to give up one single moment of his childhood to this deadly disease. It was not unusual to find him playing and racing around his backyard, wearing his medicine - laden backpack and dragging his tank of oxygen behind him. Tyler’s mom often teased him by telling him that he moved so fast she needed to dress him in red. That way, when she peered through the window to check on him playing in the yard, she could quickly spot him.

This fateful disease eventually wore down Tyler. He grew quite ill and, unfortunately, so did his HIV - infected mother. When it became apparent that he wasn’t going to survive, Tyler’s mom talked to him about death. She comforted him by telling Tyler that she was dying too, and that she would be with him soon in heaven.

A few days before his death, he whispered to me, " I might die soon. I’m not scared. When I die, please dress me in red. Mom promised she’s coming to heaven, too. I’ll be playing when she gets there, and I want to make sure she can find me."
