第二节简答题(共3小题;每小题1.5分,满分4.5分)
Tsunamis (海啸) are a series of huge waves created by an underground movement such as an earthquake or a volcanic eruption (火山喷发) . A tsunami can travel hundreds of miles per hour in the open ocean and hit the land with huge waves.
From the area where the tsunamis come, waves travel in all directions. Once the waves approach the coast, they will become more than 100 feet in height. The topography (地形) of the coastline and the ocean floor will influence the size of the wave. There may be more than one wave and the latter one may be larger than the one before. That is why a small tsunami at one beach can be a huge wave a few miles away.
All tsunamis are dangerous, even if they may not damage every coastline they strike. A tsunami can strike anywhere along most of the US coastline. Many harmful tsunamis have occurred along the coasts of California, Oregon, Washington, Alaska and Hawaii.
A movement of the ocean floor, caused by earthquakes, most often causes tsunamis. If a tsunami occurs close to a coast, the first wave could reach the beach in a few minutes, even before a warning is given. Areas are at greater risk if they are less than 25 feet above sea level and within a mile of the coastline. Drowning is the most common cause of death during a tsunami. Tsunami waves are very harmful to buildings. Other dangers include floods, pollution of drinking water, and fires from gas lines.
An accurate prediction (预报) system will allow authorities (官方) to issue timely warnings and save lives in the event of a shore-bound tsunami. But forecasting tsunamis accurately is very difficult because the ocean is usually calm before they strike land.
65. What can cause tsunamis according to the passage? ( 回答词数不超过6个 )
______________________________________________________________________________
66. What harm can a tsunami bring besides killing people and damaging buildings? ( 回答词数不超过15个 )

答案
65. Underground movements.
66. Floods, pollution of drinking water, and fires from gas lines.
67. Because usually there are no warnings before they occur.

The following conversation is between Susan Russell-Robinson from the US Geological (地质学的)Survey and Barbara Reynolds from USA Today .
Q: Why , after 600 years of no activity , did Mount Pinatubo in Philippines erupt(喷发)in 1991 ?
A: Volcanoes (火山)each have their own eruption styles . This volcano probably has a rule which makes it erupt in the order of every 500 to 1000 years , but a volcano in Hawaii seems to erupt every year , and some of the Alaskan volcanoes might erupt every 10 or 20 years .
Q: So nothing caused it ?
A: There’s nothing out of the ordinary . If you were to take an ordinary calendar year , 50 to 75 or 80 volcanoes erupt around the world every year . There are 20 to 30 volcanoes every month that show signs of unrest . That might be a full-blown eruption or a whole host of activities like that .
Q: What is “the ring of fire” ?
A: If you look at where active volcanoes are placed around the world , there are somewhere between 500 and 600 of them . There is what appears to be almost a necklace that goes around the Pacific Ocean . It makes a ring where 60% of the world’s volcanoes lie .
Q: Why such a concentration(集中)there ?
A: That’s based on a theory that the oceans and the continents are like separate pieces . When they move , one might ride up over the other one . In this case , the Pacific Ocean goes under the continents and when that happens it seems to produce magma (熔岩)at depth and then you have volcanoes in the same ring .
1.What kind of writing do you think this passage is ?
A.A text taken from a geography book . B.An interview published in the press .
C.A conversation carried out in a film . D.An oral test recorded as an example .
2.Which of the following statements can correctly explain why we have so many volcanoes around the Pacific Ocean ?
A.The movement of the surface of the earth makes it possible.
B.The Pacific Ocean produces magma and presses it everywhere.
C.The oceans and the continents are separated from each other.
D.The earth’s surface around the Pacific is thinner than any other part.
3.Barbara Reynolds’ main purpose here is______________ .
A.to show how dangerous volcanoes are to the world
B.to learn what signs a volcano gives us before its eruption
C.to warn the world of the existence of “the ring of fire”
D.to introduce some general idea of volcanoes to the public
4.Which of the following can be considered as the best conclusion of the conversation?
A.There are so many volcanoes in the world and we are always in danger.
B.Volcanoes have erupted more frequently than ever before.
C.Volcanoes are waiting to be better known.
D.Something must be done to protect the people near the ring of fire.
Space is a dangerous place, not only because of meteors (流星 ) but also because of rays from the sun and other stars. The atmosphere again acts as our protective blanket on earth. Light gets through, and this is essential for plants to make the food which we eat. Heat, too, makes our environment endurable(可忍受的). Various kinds of rays come through the air from outer space, but enormous quantities of radiation(辐射) from the sun are screened off. As soon as men leave the atmosphere they are exposed to this radiation but their spacesuits or the walls of their spacecraft, if they are inside, do prevent a lot of radiation damage.
Radiation is the greatest known danger to explorers in space. The unit of radiation is called "rem". Scientists have reason to think that a man can put up with far more radiation than 0.1 rem without being damaged; the figure of 60 rems has been agreed on. The trouble is that it is extremely difficult to be sure about radiation damage - a person may feel perfectly well, but the cells of his or her sex organs may be damaged, and this will no be discovered until the birth of abnormal children or even grandchildren.
Missions of the Apollo flights have had to cross belts of high amount of rems. So far, no dangerous amounts of radiation have been reported, but the Apollo missions have been quite short. We simply do not know yet how men are going to get on when they spend weeks and months outside the protection of the atmosphere, working in a space laboratory. Drugs might help to decrease the damage done by radiation, but no really effective ones have been found so far.
1. According to the first paragraph, the atmosphere is essential to man in that ____.
A. it protects him against the harmful rays from space
B. it provides sufficient light for plant growth
C. it supplies the heat necessary for human survival
D. it screens off the falling meteors
2. We know from the passage that ____.
A. exposure to even tiny amounts of radiation is deadly
B. the effect of exposure to radiation is slow in coming
C. radiation is avoidable in space exploration
D. astronauts in spacesuits needn"t worry about radiation damage
3. The harm radiation has done to the Apollo crew members ____
A. is significant B. seems overestimated
C. is enormous D. remains unknown
4. It can be inferred from the passage that ____.
A. the Apollo mission was very successful
B. protection from space radiation is no easy job
C. astronauts will have deformed children or grandchildren
D. radiation is not a threat to well-protected space explorers
45. The best title for this passage would be ____.
A. The Atmosphere and Our Environment B. Research on Radiation
C. Effects of Space Radiation D. Importance of Protection Against Radiation
E
After a busy day of work and play, the body needs to rest. Sleep is necessary for good health. During this time, the body recovers from the activities of the day. The rest that you get while sleeping makes it possible for your body to prepare itself for the next day.
There are four levels of sleep, each being a little deeper than the one before. As you sleep, your body relaxes little by little. Your heart beats more slowly, and your brain slows down. After you reach the fourth level, your body shifts(变换) back and forth from one level to the other.
Although your mind slows down, you will dream from time to time. Scientists who study sleep point out that when dreaming occurs, your eyeballs begin to move more quickly (although your eyelids are closed). This stage of sleep is called REM, which stands for rapid eye movement.
If you have trouble falling asleep, some people recommend(建议) breathing very slowly and very deeply. Other people believe that drinking warm milk will make you drowsy. There is also an old suggestion that counting sheep will put you to sleep.
49. During REM, ______
A. you move restless B. you start dreaming
C. your mind stops working D. your eyeballs move quickly
50. A good title for this text might be_________
A. Dreams B. Sleep C. Good Health D. Work and Rest

The academy began in the early 1750’s with Benjamin Franklin’s school in Philadelphia, which later became the University of Pennsylvania. It extended generally to about the middle nineteenth century, except in the southern states where the public high school was late in developing and where the academy continued to be a principal means of secondary education even after 1900.The academy was open to girls as well as to boys, and it provided a wider curriculum than what the Latin grammar school had furnished. It was designed not only as a preparation for college but also for practical life in commercial and business activities. Although its wide educational values are evident and are recognized as important contributions to secondary education in this country, the academy has never been considered a public institution as the public high school has come to be.
The public high school had its origin in Massachusetts in 1821 when the English Classical School was established in Boston. In 1827,the state enacted(制定)the first state wide public high school law in the United States. By 1840,there were perhaps a dozen public high schools in Massachusetts and many in other eastern states by 1850,they could also be found in many other states. Just as the curriculum of the academy grew out of that of the Latin grammar school, the curriculum of the public high school developed out of that of the academy. The public high school in the United States is a repudiation(推翻) of the aristocratic(贵族的)and selective principle of the European educational tradition. Since 1890,enrollments( 入学)in secondary schools, mainly public high schools, have practically doubled in this country every ten years.
56.According to the passage, which of the following sequences indicates the order in which the schools developed?
A.Latin grammar school, public high school, academy.
B.Latin grammar school, academy, public high school.
C.Public high school, Latin grammar school, academy.
D.Public high school, academy, Latin grammar school.
57.It is the opinion of the author that the academy, compared with the public high school, was ____.
A.obviously academically better
B.more discriminatory in student selection
C.coeducational
D.not generally considered as a public institution
58.One can probably infer from his article that “Latin grammar school” refers to ____.
A.the Boston Free Latin School
B.all the elementary schools in the United States
C.schools which taught Latin, exclusive of all other subjects
D.a number of schools which developed in New England
59.It is implied but not stated in the passage that ____.
A.European educational systems are not good
B.As high schools developed in the united states, the decision was made to make them responsible to people from all classes of society.
C.There was an aristocratic and selective principle in the European educational tradition
D.public high schools in the United States embraced the European educational tradition
