During the 2016 Summer Olympic Games in Rio de Janeiro, many world records were broken. They fell in swimming, cycling, running and a number of other sports. How do athletes continue to get better, jump longer, run or swim faster? Although scientists say that athletes have reached their limits (极限), records continue to fall. In almost every sport athletes have become better since the Olympic movement began.

One reason is that more and more people than ever before have access to sports and exercise. They start at an earlier age and can compete longer in their sports. In schools more and more natural talents can be discovered. Another reason is that athletes can train harder and, as professionals, concentrate wholly on their sports instead of rushing to a training session after their day job. As medicine improves, athletes can stay in competition for a longer time and overcome injuries faster. Technology has also helped improve scores and equipment is getting better. One of the most important factors, however, is the human mind. It lies in our nature to be better and faster than someone else. The will to break a barrier (障碍) can release great power in your body.

So, where are the limits? Some years ago, nobody thought a person could run under 10 seconds in the 100-meter dash. But the record was broken at the 1968 Mexico City Olympics.

At the moment Usain Bolt is the fastest man on earth at 9.58 seconds. Scientists say that 9.48 may be the absolute (绝对的) limit for running such a distance, but, who knows, maybe some runner will one day run under 9 seconds.

1．What does the underlined word “fall” in Paragraph 1 mean? A．Change. B．Increase. C．Drop down. D．Be broken.

2．What can we learn from Paragraph 2? A．Training session is popular with athletes.

B．People's will plays a key role in their winning. C．More and more people are interested in sports.

D．Athletes are free from injuries because of technology. 3．Why does the author tell us about Usain Bolt? A．To prove no one can break his record. B．To show he is the most successful runner.

C．To tell us we won't know human beings' limits. D．To explain why a human being can run so fast. 4．What's the main idea of the text? A．Have athletes reached their limits? B．Get better, jump longer and run faster.

C．Why do athletes keep breaking world records?

D．Many world records were broken in Olympic Games.

B

Dogs are our best friends. That's especially true after a disaster, such as an earthquake. When buildings fall down, search-and-rescue dogs help find trapped people. Dogs' amazing noses can

pick up the smell of survivors. Now scientists have developed an electronic tool that does the same thing. It's taking smell detection (探测) to a whole new level.

The new invention is a sort of electronic nose, which can detect extremely low levels of many compounds (化合物) from people's skin. This isn't the first time engineers have developed such an object. Earlier models, however, have been bulky and expensive. They could not detect low levels of target compounds either. The new one is inexpensive and small enough to fit inside hand-held equipment.

The electronic nose can detect extremely slight smell of more than one compound at the same time. “Being able to do this, in such a small object, is the significant discovery，” says Sotiris E. Pratsinis, Professor of Process Engineering & Materials Science at the Swiss Federal Institute of Technology in Zurich. His team tested it in special spaces. They were like the small spaces where people might be trapped. Chemicals given off by the volunteers built up inside. The electronic equipment detected those compounds at unbelievably low levels.

The results were good news for the research team. But they may be not for our four-legged friends, who could soon be out of a job. “Ideally, this technology could replace search-and-rescue dogs，” Pratsinis says.

Stephen Taylor, an electrical engineer, agrees that the new technology has some benefits over dogs. Still, he thinks it may be too soon to have our trusty friends retire. He suspects, “I foresee that such an object could add to the fine work done by the dogs.” Taylor also pointed out some potential limitations of the new invention. “E-noses are useful, but can be very likely to be

affected by unstable readings and interruption，” he says.

5．Why does the author talk about dogs at the beginning? A．To catch the readers' attention. B．To introduce the topic about e-noses.

C．To show what search-and-rescue dogs do.

D．To add background information for discussion.

6．Which of the following best explains “bulky” underlined in Paragraph 2? A．Complex. B．Fragile. C．Handy. D．Large.

7．What is Paragraph 3 mainly about? A．What e-noses' working principle is.

B．How e-noses are made.

C．What differences between dogs and e-noses are.

D．How powerful e-noses are.

8．What does Stephen Taylor mean? A．Dogs and e-noses could work together.

B．Search-and-rescue dogs will retire soon.

C．E-noses are more reliable than noses of dogs. D．Dogs are better at finding out trapped people. Ⅱ.七选五
