题目内容

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 (导航) 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 (独特的) isthat 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 thefastest 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.

We live in a sweet world. An average American kid consumes(消耗) more than 20 teaspoons of sugar per day, and adults eat 50% more sugar today than they did in the 1970s. We all know that too much sugar isn’t good for us. Researchers at the University of Utah used mice to make a study to prove the toxic effects of eating more sugar. They found it could influence people’s health seriously.

During the 58-week-long study, mice were fed a diet containing 25% more sugar. This percentage is equal to a healthy human diet along with three cans of soda daily. The team found that these mice were twice as likely to die as mice without eating so much sugar. Though the mice did not show signs of obesity or high blood pressure, male mice produced 25% fewer offspring(后代) than the other mice.

The reason why mice were chosen for research by scientists is not far to seek. “Mice have the genetic(基因) structure similar to humans’. Most substances(物质) that are harmful to mice are also harmful to people; it’s likely that those important physical problems that cause the rising death rate among mice can also influence people,” says the study author James Ruff of the University of Utah. Findings from this study reveal negative effects that are not as detectable as weight gain or heart problems. Sugar can contribute to long-term changes in the body that can affect development and even shorten lives.

Different types of sugar have different effects on the human body. Some of the sugar we consume comes from foods we might expect—candy, soda, and cookies. But much of the sugar that we eat is hidden. Food companies add large amounts of sugar to items we may not classify as sweets. To help cut down extra sugar consumption, nutrition experts suggest looking at the ingredients on food packages. Cutting sugar out of the American diet altogether may be difficult, but making every effort to control our nation’s desire for sugar will avoid a sweeter future.

1.The underlined word “toxic” in Paragraph1 probably means “________”.

A. positive B. harmful C. doubtful D. reasonable

2.According to Paragraph 2, we can know ________.

A. mice eating more sugar will live longer

B. the study on mice lasted less than a year

C. the study showed the bad effects of more sugar on mice

D. mice eating more sugar will become fatter and fatter

3.Why did the scientists choose mice to do the study?

A. Because a substance may have the same effects on mice and humans.

B. Because mice have a longer lifespan (寿命) than other animals.

C. Because mice can take in the harmful substances easily and quickly.

D. Because mice are sensitive to the sweet taste.

4.It can be inferred from the last paragraph that ________.

A. sugar from candy, soda and cookies is helpful for us

B. we should never believe what food companies said

C. most types of sugar have similar effects on people

D. it’s necessary to control people’s wish for sugar

In most parts of the world, as far back as anyone can remember , there has been a puppet（木偶）tradition. Although some of us think of puppets as children’s entertainment, they were----and oftenstill are used to tell serious stories to adult audiences. Even in these days of special effects, the puppettheatre still has a special place in many cultures.

The best known puppet characters in Britain are Punch and Judy, glove puppets with woodenheads. In summer, one basic play of about half an hour is performed on beaches all around Britain .Mr. Punch, who has an enormous nose and wears a curved hat, gets into trouble and has argumentswith his wife, Judy. A policeman , a crocodile, and a hangman, and all of them run after Mr. Punch .He ,of course, invariably manages to survive to fight another day .

In Belgium wooden puppets first appeared in the 1820s in cities like liege . The liege puppetsare in fact string puppets without strings！They have a single rod（棒）attached to their heads, whichmeans the puppeteers aren’t able to raise the arms and legs, but can move the body up and down and the head from side to side. Many of the stories used to be historical or religious but it is Tchantches,a comic character wit patched trousers and a big black hat, who is the best loved character today. LikeMr. Punch, he is a simple man who is also greedy, quarrelsome and lazy. He makes fun of everyone, but is often warm--hearted and tender.
