Imagine you are in a jumping contest. Animals and insects can also enter this contest. But they might just leave humans in the dust!
The first event is the long jump. The human athlete is Mike Powell. In 1991, he jumped nearly 30 feet, which is the world record for the long jump. That is about five times his own height.
His competitor in the long-jump contest is a frog named ¡°Rosie the Ribbiter.¡± Rosie set the world record for frogs in 1986 by jumping more than 21 feet. Her record has never been broken by any other frog. Compared to Mike Powell, Rosie¡¯s jump is not that amazing. But wait! Rosie is only about 10 inches long when her legs are stretched to their full length. She can jump more than 25 times her size. Rosie, the frog, wins the long-jump event.
The next event is the high jump. Javier Sotomayor, the world record holder, can jump a bar (ºá¸Ë) 8 feet high. That is about as high as the ceiling in most homes.
Looking around for someone to challenge his record, Javier might need a magnifying glass (·Å´ó¾µ). The next contestant is a tiny insect called the spittlebug (´µÄ³æ).
The spittlebug can jump 28 inches into the air. It is only a quarter-inch long, less than the width of a pencil. If the spittlebug were the same size as Javier, it would be able to jump 600 feet into the air. That is like a human jumping over a building 55 stories high!
Though the humans lose the ¡°jumping contest,¡± their competitors would probably agree that Mike and Javier are still pretty excellent athletes. If only Rosie and the spittlebug could speak!
1.The underlined word ¡°contestant¡± in Paragraph 5 means ¡°_____¡±.
A. coachB. teammateC. challengerD. record holder
2.What can we learn about the spittlebug?
A. It likes living on the ceiling.
B. It is good at flying in the air.
C. It is the same length as a pencil.
D. It has a wonderful jumping talent.
3.In the author¡¯s opinion, Rosie and the spittlebug¡¯s jumping abilities are ________.
A. surprisingB. promisingC. doubtfulD. fearful
4.How does the author develop the text?
A. By giving instructions.
B. By making comparisons.
C. By following the order of time.
D. By following the order of importance.

Here is an astonishing and significant fact: Mental work alone can¡¯t make us tire. It sounds absurd. But a few years ago, scientists tried to find out how long the human brain could labor without reaching a stage of fatigue (Æ£ÀÍ). To the amazement of these scientists, they discovered that blood passing through the brain, when it is active, shows no fatigue at all! If we took a drop of blood from a day laborer, we would find it full of fatigue toxins(¶¾ËØ) and fatigue products. But if we took blood from the brain of an Albert Einstein, it would show no fatigue toxins at the end of the day.
So far as the brain is concerned, it can work as well and swiftly at the end of eight or even twelve hours of effort as at the beginning. The brain is totally tireless. So what makes us tired?
Some scientists declare that most of our fatigue comes from our mental and emotional(ÇéÐ÷µÄ) attitudes. One of England¡¯s most outstanding scientists, J.A. Hadfield, says, ¡°The greater part of the fatigue from which we suffer is of mental origin. In fact, fatigue of purely physical origin is rare.¡± Dr. Brill, a famous American scientist, goes even further. He declares, ¡°One hundred percent of the fatigue of sitting worker in good health is due to emotional problems.¡±
What kinds of emotions make sitting workers tired? Joy? Satisfaction? No! A feeling of being bored, anger, anxiety, tenseness, worry, a feeling of not being appreciated¡ªthose are the emotions that tire sitting workers. Hard work by itself seldom causes fatigue. We get tired because our emotions produce nervousness in the body.
1.What amazed the scientists a few years ago?
A. Fatigue toxins could hardly be found in a laborer¡¯s blood.
B. Albert Einstein didn¡¯t feel worn after a day¡¯s work.
C. The brain could work for many hours without fatigue.
D. A mental worker¡¯s blood was filled with fatigue toxins.
2.According to the author, which of the following can make sitting workers tired?
A. Challenging mental work.B. Unpleasant emotions.
C. Endless tasks.D. Physical labor.
3.What¡¯s the author¡¯s attitude towards the scientists¡¯ idea?
A. He agrees with them.
B. He doubts them.
C. He argues against them.
D. He hesitates to accept them.
4.We can infer from the passage that in order to stay energetic, sitting workers need to ___________.
A. have some good foodB. enjoy their work
C. exercise regularlyD. discover fatigue toxins

In Los Angeles, drivers spend sixty-one hours every year stuck in traffic. These drivers know all too well how bad the traffic can be. ¡°There¡¯re too many cars, and you can¡¯t move around a lot.¡±
Professor Cyrus Shahabi also knows about traffic jams. He lives more than 65 kilometers from his office at the University of Southern California, in Los Angeles. He is always late even with the help of a navigation (µ¼º½) system.
He decided to develop a program called ClearPath for that. He says his program uses historical data to predict traffic conditions even before the driver leaves the house. ¡°What¡¯s unique (¶ÀÌصÄ) is that we use a lot of data that¡¯s currently become available including traffic data, weather data, and we analyze that so that we can predict what¡¯s going to happen in front of you when leave home.¡±
Professor Shahabi says his system does more than just answer current traffic conditions. With ClearPath, he says, a driver can decide what time he wants to leave, and ClearPath will give the fastest route. It looks at the entire road network, including surface streets as well as highways, before the driver hits the road. Professor Shahabi hopes to have ClearPath available nationwide and overseas once they can collect traffic data from other cities.
¡°I always thought that Los Angeles had the worst traffic, but now I know that Shanghai, Beijing, Seoul, Tokyo, believe it or not, Singapore, Hong Kong certainly are examples that can immediately use this.¡±Professor Shahabi hopes to share this new technology with companies that already have navigation systems, such as Google and Apple.
