Every country had its heroes. The heroes are the people that nation and especially the young peo??ple 21_____ . If you get a list of the 22   _____of a nation, it will tell you the potential (潜力)of the nation.

If today in America ’ you ask the high school students to list their heroes their 23____ would prob??ably divide into three groups. rHie first group of heroes would be the rock stars—the people 24 _____with rock music. There is no doubt that such people do have talent (天才)but one 25_____ if one should hold up rock stars as model. The rock stars too often are mixed with drugs and their personal life isnot all that — 26 ____  . The rock stars are rich and wear the latest fashion styles (时装).However oneshould 27 _____more in a hero than such things as 28______ and fine clothes.

A second type of heroes for the American youth are sports stars. Again you have a person who has a great talent in one area_ 29 _____. However, too often the personal life of the sports star is a bit 30_____. Too frequently drugs and drinking are a part of 31_____ of the sports stars.

A third group of heroes are TV or movie stars. These people may have lots of 32___ ,tal??ent and are quite handsome. However ’ the personal life of too many actors is quite sad and should not be held up as a 33____  for young people.

Today,the rock stars,the sportsmen  and the actors 34____ have become the models of the youth in America. Really,do you hear a young person say that his 35____ is a doctor, a teacher or a scientist? These people are not 36____ and do not wear fashionable clothes. However, they are 37____ people who work hard to make the world a better place for everyone.

What is really sad is that the young try to 38____ their heroes. They like to wear the same clothes as theirs, if the heroes of today for the American youth are 39 ____only to rock stars, sportsmen and actors, the future does not look too 40_____ .

A report, published in last week's Journal of the American Medical Association, offers a picture of how risky it is to get a lift from a teenage driver. Indeed, a 16-year-old driver with three or more passengers is three times as likely to have a fatal(致命)accident as a teenager driving alone. By contrast, the risk of death for drivers between 30 and 59 decreases with each additional passenger.
The author also found that the death rates for teenage drivers increased dramatically after 10 p. m.,and especially after midnight. With passengers in the car,the driver was even more likely to die in a late night accident.
Robert Foss, a scientist at the University of North Carolina Highway Safety Research Center, says the higher death rates for teenage drivers have less to do with "really stupid behavior" than with just a lack of driving experience. "The basic thing, "he says, "is that adults who are responsible for issuing(发放) licenses fail to recognize how skilled a task driving is. "
Both he and the author of the study believe that the way to reduce the harm is to have so-called graduated licensing systems, in which getting a license is a slower process. A graduated license requires that a teenager first prove himself capable of driving in the presence of an adult, followed by a period of driving at night with a limited number of passengers before graduating to get a full driving license.
Graduated licensing systems have reduced teenage driver crashes, according to recent studies. About half of the states now have some sort of graduated licensing system in place, but only 10 of those states have number limitation on passengers. California is the strictest, with a new driver prohibited from carrying any passenger under 20 for the first six months.
76.Which of the following situations is most dangerous according to the passage?
A. Adults giving a lift to teenagers on the highway after 10 p. m.
B. A teenager driving after midnight with passengers in the car.
C. Adults driving with three or more teenage passengers late at night.
D. A teenager getting a lift from a stranger on the highway at midnight.
77.According to Robert Foss, the high death rate of teenage drivers is mainly due to_______.
A. their frequent driving at night         B. their lack of driving experience
C. their improper way of driving         D. their driving with passengers
78.Which of the following statements is true according to Paragraph 3 ?  
A. Teenagers should spend more time learning to drive.
B. Driving is a skill too difficult for teenagers to learn.
C. Teenagers should be limited in taking driving lessons.
D. People issuing license are partly responsible for the accidents.
79.A suggested measure to be taken to reduce teenagers'driving accidents is that_______
A. driving in the presence of an adult should be made a rule.
B. they should be forbidden to take on passengers
C. they should not be allowed to drive after 10 p. m.
D. the licensing systems should be improved
80.The present situation in about half of the states is that the graduated licensing system_______.
A. is under discussion              B. is about to be set up
C. has been put into effect                 D. has been perfected

Phys ed (physical education) is making a comeback as a part of the school core curriculum(核心课程), but with a difference. While group sports are still part of the curriculum, the new way is to teach skills that are useful beyond gym class. Instead of learning how to climb a rope, children are taught to lift weights, balance their diets and build physical endurance. In this way,kids are given the tools and skills and experiences so they can lead a physically active life the rest of their life.

Considering that 15 percent of American children 6 to 18 are overweight, supporters say more money and thought must be put into phys ed curriculum. In many cases, that may mean not just replacing the old gym-class model with fitness programs but also starting up phys ed programs because school boards often "put P.E. on the chopping block, cutting it entirely or decreasing its teachers or the days it is offered," says Alicia Moag-Stahlberg, the executive director of Action for Health Kids. The difference in phys ed programs is partly due to the lack of a national standard. "Physical education needs to be part of the core curriculum," she added.

The wisdom of the new approach has some scientific support. Researchers at the University of Wisconsin have demonstrated how effective the fit-for-life model of gym class can be. They observed how 50 overweight children lost more weight when they cycled and skied cross-country than when they played sports. The researchers also found that teaching sports like football resulted in less overall movement, partly because reluctant students were able to sit on the bench.

Another problem with simply teaching group sports in gym class is that only a tiny percentage of students continue playing them after graduating from high school. The new method teaches sells that translate to adulthood.

For years, the automobile industry has been testing vehicles that use hydrogen as fuel. Now, people across the United States have had a chance to see and even drive cars that get power from hydrogen fuel cells (燃料电池).

But the hydrogen fuel cell is not a new idea. The fuel cell was first invented by Sir William Grove of Britain in 1839. Since then, many different designs, have been invented. There is one place where fuel cells are a proven technology: in space. The American space agency used fuel cells in its Apollo spaceships in the twentieth century.

The most useful fuel cell for transportation purposes is the Polymer Electrolyte Membrane, or P.E.M. fuel cell. It is simple and can operate at temperatures of sixty to eighty degrees Celsius. That is much lower than other fuel cell designs. A P.E.M. fuel cell has two sides divided by a thin membrane (膜). Hydrogen gas is forced through one side where it comes in contact with a reactive material containing the metal platinum(铂). The membrane separates the electrons(电子) from the protons(质子) in the hydrogen atoms. The protons pass through it to the other side of the fuel cell. But the electrons are captured to do work; like powering a motor. Oxygen from the air is forced into the other side of the fuel cell. There, the gas meets the protons that have passed through the membrane. They combine to form water and heat. A single fuel cell does not produce a lot of electricity. But when many fuel cells are combined, they can produce enough electricity to power a vehicle. The product of the chemical reaction that powers fuel cells is water. This makes fuel cells a very clean technology.

Hydrogen fuel cell cars have been slow to develop because of many technical problems that have to be solved. For example, it is unclear how long the membranes in P.E.M. fuel cells will last. Also, fuel cells need water for their chemical reactions. They must be designed to start easily at low temperatures and in dry climates. And smaller, less costly fuel cells must be designed before they can truly take the place of gasoline engines. Now more models of fuel cell vehicles are being tested than ever before. The threat of climate change and the high cost of oil have increased interest in these vehicles that do not cause pollution.
