B
Events such as hurricanes, earthquakes, floods, volcanic eruptions, and tornadoes are all natural disasters. They are mostly related to the weather. Some are predictable ----like a hurricane. Some, like an earthquake, surprise us. It is necessary for us to learn about them, so we can be prepared!
Flooding happens during heavy rains, when rivers overflow, when ocean waves come onshore, when snow melts too fast or when dams or banks break. Flooding is the most common of all natural disasters.
Hurricanes are severe tropical storms that form in the southern Atlantic Ocean, Caribbean Sea, Gulf of Mexico, and in the Pacific Ocean. Hurricanes gather heat and energy through contact with warm ocean waters. Evaporation(蒸發) from the sea water increases their power.
Hurricanes have winds at least 74 miles per hour. When they come onto land, the heavy rain, strong winds and heavy waves can damage buildings, trees and cars.
Tornadoes are nature’s most violent storms. Tornadoes must always be taken seriously. Tornadoes can be very dangerous ---- sometimes even deadly. They come from powerful thunderstorms and appear as moving. Tornado winds can reach 300 miles per hour. They cause damage when they land the ground. They can damage an area one mile wide and 50 miles long.
While thunder won't hurt you ----lightning will! So it's important to pay attention when you hear thunder. Thunderstorms happen mostly in summer and every thunderstorm has lightning. Lightning can strike people and buildings, which is very dangerous.
Thunderstorms affect small areas when compared with hurricanes and winter storms. The typical thunderstorm is 15 miles in diameter and lasts an average of 30 minutes.
A volcano is a mountain with a large opening at the top through which melting rock, steam, gases escape from time to time with violent force from inside the earth. When pressure increases, eruptions occur. Gases and rock shoot up through the opening fill the air with small pieces. Erupt
ions can cause lava flows, hot ash flows, mudslides, falling ash and floods, which is likely to knock down entire forests, cause floods and earthquakes. Fresh volcanic ash can cause damage to the lungs of older people, babies and people with respiratory problems.
64. From the passage, we know that ______.
A. all natural disasters can be predicted
B. all natural disasters are connected with the weather.
C. human beings can do nothing with natural disasters
D. the more we know about natural disasters, the less we will suffer.
65. Which of the following is NOT true according to the passage?
A. Flooding is the most common natural disaster.
B. Hurricanes and tornadoes can land the ground and cause damage.
C. Thunder can strike people and buildings.
D. Fresh volcanic ash can cause illnesses.

There was one thought that air pollution affected only the area immediately around large cities with factories and heavy automobile traffic. At present, we realize that although these are the areas with the worst air pollution, the problem is literally worldwide. On several occasions over the past decade, a heavy cloud of air pollution has covered the east of the United States and brought health warnings in rural areas away from any major concentration of manufacturing and automobile traffic. In fact, the very climate of the entire earth may be infected by air pollution. Some scientists consider that the increasing concentration of carbon dioxide in the air resulting from the burning of fossil fuels (coal and oil) is creating a “greenhouse effect”— conserving heat reflected from the earth and raising the world’s average temperature. If this view is correct and the world’s temperature is raised only a few degrees, much of the polar ice cap will melt and cities such as New York, Boston, Miami, and New Orleans will be in water.
Another view, less widely held, is that increasing particular matter in the atmosphere is blocking sunlight and lowering the earth’s temperature — a result that would be equally disastrous. A drop of just a few degrees could create something close to a new ice age, and would make agriculture difficult or impossible in many of our top farming areas. Today we do not know for sure that either of these conditions will happen (though one recent government report drafted by experts in the field concluded that the greenhouse effect is very possible). Perhaps, if we are lucky enough, the two tendencies will offset each other and the world’s temperature will stay about the same as it is now. Driven by economic profits, people neglect the damage on our environment caused by the “advanced civilization”. Maybe the air pollution is the price the human beings have to pay for their development. But is it really worthwhile?
As pointed out at the beginning of the passage, people used to think that air pollution _______.
A. cause widespread damage in the countryside
B. affected the entire eastern half of the United States
C. had damaged effect on health
D. existed merely in urban and industries areas
As to the greenhouse effect, the author __________.
A. share the same view with the scientist.
B. is uncertain of its occurrence
C. rejects it as being ungrounded
D. thinks that it will destroy the world soon
The word “offset” in the second paragraph could be replaced by _________.
A. slip into B. make up for C. set up D. catch up with
It can be concluded that ____________.
A. raising the world’s temperature only a few degrees would not do much harm to life on earth
B. lowering the world’s temperature merely a few degrees would lead major farming areas to disaster
C. almost no temperature variations have occurred over the past decade
D. the world’s temperature will remain constant in the years to come
This passage is primarily about __________.
A. the greenhouse effect B. the burning of fossil fuels
C. the potential effect of air pollution D. the likelihood of a new ice age

Some people think that as more and more people have televisions in their homes, fewer and fewer people will buy books and newspapers. Why read an article in the newspaper, when the TV news can bring you the information in a few minutes and with pictures? Why read the life story of a famous man, when a short television program can tell you all that you want to know?
Television has not killed reading, however. Today, newspapers sell in very large numbers. And books of every kind are sold more than ever before. Books are still a cheap way to get information and enjoyment. Although some books with hard covers are expensive, many books are printed today as paperbacks (平裝本), which are quite cheap. A paperback collection of short stories, for example, is always cheaper than an evening at the cinema or the theater, and you can keep a book for ever and read it many times.
Books are a wonderful provider of knowledge and pleasure and some types of books should be in every home. Every home should have a good dictionary. A good encyclopedia (百科全書), though expensive, is useful, too, because you can find information on any subject. Besides, you can have such books as history books., science textbook, cookbooks, and collections of stories and poems. Then from time to time you can take a book of poems off your shelves and read the thoughts and feelings of your favorite poets.
It can be inferred from the passage that ________.
A. TV programs are a chief provider of knowledge
B. cinemas are the best choice in getting information
C. reading is a cheap way of learning and having fun
D. newspapers are an expensive way to enjoy oneself
What does the sentences “Television has not killed reading, however ” underlined in the second paragraph suggest?
A. People only need reading, though. B. Reading is still necessary today.
C. Reading is more fun than television. D. Watching television doesn’t help reading.
What can we learn from the passage?
A. Fewer and fewer people will buy books.
B. A good dictionary should be kept in every home.
C. Books with hard covers sell better than paperbooks.
D. More people like TV programs about famous men.
