In the second half of each year ,many powerful storms are born in the tropical Atlantic and Caribbean Sea .Of these , only about half a dozen produce the strong , circling winds of 75 miles per hour or more that give them hurricane status, and several usually make their way to the coast. There they cause millions of dollars of damage, and bring death to large numbers of people.

The great storms that hit the coast start as innocent circling disturbances (扰乱) hundreds or thousands of miles out to sea . As they travel aimlessly over water warmed by the summer sun, they are carried westward by the trade winds(信风)When con­ditions are just right , warm , moist air flows in at the bottom of such a disturbance , moves upward through it and comes out at the top . In the process, the moisture in this warm air produces rain, and with it the heat is changed into energy in the form of strong winds. As the heat increases , the young hurricane begins to swirl (旋转)in a counterclockwise(逆时针方向) motion.

The average life of a hurricane is only about nine days, but is contains almost more power than we can imagine. The energy in the heat released by a hurricane's rainfall in a single day would satisfy the entire electrical needs of the United States for more than six months. Water, rather than wind is the main source of death and destruction in a hurricane. A typical hurricane brings 6 to 12-inch downpours resulting in sudden floods. Worst of all is the powerful movement of the sea —the mountains of water moving toward the low—pressure hurricane center, the water level rises as much as 15 feet above normal as it moves toward shore.

A recent study offers a picture of how dangerous 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 accident as a teenager driving alone. However, the possibility of death for drivers between 30 and 59 decreases with each additional passenger.

It was also found that the death rates for teenage drivers increased greatly after10 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. Both he and the author of the study believe that the way to help solve the problem is to have states setting up so-called graduated licensing systems (等级执照制). A graduated license requires that a teenager first prove himself able to drive in the presence of an adult, fol­lowed by a period of driving with a limited number of passengers, before graduating to full driving on his own. About half of the states now have some sort of graduated licensing system in place. The systems have reduced teenage driver crashes, according to recent studies.

1.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.

2.According to Robert Foss, the high death rate of teenage drivers is mainly due to _______.

    A.their frequent driving at night             B.their improper way of driving

    C.their lack of driving experience           D.their driving with passengers

3.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 stopped from taking on passengers

    C.they should not be allowed to drive after 10 p. m.

    D.the licensing system should be improved

4.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

Fear and its companion pain are two of the most useful things that men and animals possess, if they are properly used. If fire did not hurt when burnt, children would play it until their hands were burnt away. Similarly, if pain existed but fear did not, a child would burn itself again and again, because fear would not warn it to keep away from the fire that had burnt it before. A really fearless soldier— and some do exist — is not a good soldier because he is soon killed ; and a dead soldier is of no use to his army. Fear and pain are therefore two guards without which men and animals might soon die out.

In our first sentence we suggested that fear ought to be properly used.If, for example, you never go out of your house because of the danger of being knocked down and killed in the street by a car, you are letting fear rule you too much. Even in your house you are not completely safe: an airplane may crash on your house, or ants may eat away some of the beams in your roof so that the lat­ter falls on you, or you may get cancer!

The important thing is not to let fear rule you, but instead to use fear as your servant and guide. Fear will warn you of dangers; then you have to decide what action to take.

In many cases, you can take quick and successful action to avoid the dan­ger. For example, you see a car coming straight towards you: fear warns you, you jump out of the way, and all is well.

In some cases, however, you decide that there is nothing that you can do to avoid the danger. For example, you cannot prevent an airplane crashing onto your house. In this case, fear has given you its warning, you have examined it and decided on your course of action, so fear of this particular danger is no lon­ger of any use to you, and you have to try to overcome it.

1.Children would play with fire until their hands were burnt away if ________.

    A.they were given no warning beforehand

    B.they had never burnt themselves

    C.they had no sense of pain

    D.they were fearful of the fire      

2.A really fearless soldier_________.

    A.is of little use to the army                  B.is without equal

    C.is nothing but a dead soldier                D.easily gets killed in a battle

3.Fear should be used properly because_________.

    A.an airplane may crash on your house                                    

    B.you may get cancer

    C.fear can only be used as a servant and guide

    D.men are now letting fear rule them too much

4.Which of the following is implied but not stated in the passage?

    A.Fear is always something helpful.

    B.Too much fear is harmful.

    C.Fear ought to be used as a servant and guide.

       D.Fear is something unbeneficial.
