The desire to make explorations is born with man. Wherever his imagination goes, man also has a strong wish to go. A large part human history is connected with the exploration of the world in which we live. Again and again people have set out with surprising courage and patience to look into unknown regions and lands to see what had not yet been seen, to make known the unknown. With kites, balloons and aircraft they left the ground to pass through the lower atmosphere. Now the outer space receives their attention.
Why should man take the trouble of conquering space? It is hard to list the specific practical benefits that will result in. But one knows, from past experience in other areas, that man will surely see and discover new things in space that will increase our scientific knowledge, and this new knowledge will find its way into valuable practical uses. What we learn about man himself, from his experience in space, and from the effects of space and the space flight environment on him, will be extremely valuable. The new techniques developed to carry out the exploration of space, and to keep man alive in space, will certainly find practical uses in everyday life in some way. The areas that will benefit are manifold. They include communication, generation of power, transportation and travel, food production, materials, fuels and many others. But to say definitely just what the practical results will be is almost impossible.

The main idea of the first paragraph is that __________.

A rainforest is an area covered by tall trees with the total high rainfall spreading quite equally through the year and the temperature rarely dipping below l6℃. Rainforests have a great effect on the world environment because they can take in heat from the sun and adjust the climate. Without the forest cover，these areas would reflect more heat into the atmosphere，warming the rest of the world. Losing the rainforests may also influence wind and rainfall patterns，potentially causing certain natural disasters all over the world.
In the past hundred years，humans have begun destroying rainforests in search of three major resources（资源）：land for crops，wood for paper and other products，land for raising farm animals. This action affects the environment as a whole. For example，a lot of carbon dioxide in the air comes from burning the rainforests. People obviously have a need for the resources we gain from cutting trees but we will suffer much more than we will benefit.
There are two main reasons for this. Firstly，when people cut down trees，generally they can only use the land for a year or two. Secondly，cutting large sections of rainforests may provide a good supply of wood right now，but in the long run it actually reduces the world’s wood supply.
Rainforests are often called the world’s drug store. More than 25％ of the medicines we use today come from plants in rainforests. However，fewer than l％of rainforest plants have been examined for their medical value. It is extremely likely that our best chance to cure diseases lies somewhere in the world’s shrinking rainforests.

A few years ago it was popular to speak of a generation gap, a disagreement between young people and their elders．Parents said that children did not show them proper respect and obedience(服从), while children complained(抱怨)that their parents did not understand them at all．What had gone wrong? Why had the generation gap suddenly appeared? Actually the generation gap has been around for a long time．Many people argue that a gap is built into the fabric(结构)of our society．
One important cause of the generation gap is the chance that young people have to choose their own ways of life．In more traditional societies, when children grow up, they are expected to live in the same area as their parents, to marry people that their parents know and agree to, and to continue the family occupation(职业)．In our society, young people often travel great distances for their education, move out of the family home at an early age, marry or live with people whom their parents have never met, and choose occupations different from those of their parents．
In our easily changing society, parents often expect their children to do better than they did: to find better jobs, to make more money, and to do all the things that they were unable to do．Often, however, the strong desire that parents have for their children are another cause of the disagreement between them．Often, they discover that they have very little in common with each other．
Finally, the speed at which changes take place in our society is another cause of the gap between the generations．In a traditional culture, elderly people are valued for their wisdom, but in our society the knowledge of a lifetime may become out of date overnight．The young and the old seem to live in two very different worlds, separated by different skills and abilities．
No doubt, the generation gap will continue to be a feature(特点)of American life for some time to come．Its causes are rooted in the freedom and changes of our society, and in the rapid speed at which society changes．
【小题1】The main idea of the first paragraph is that _______．

A study of more than five million books, both fiction and non-fiction, has found a marked decline in the use of emotional words over time. The researchers form the University of Bristol used Google Ngram Viewer, a facility for finding the frequency of terms in scanned books, to search for more than 600 particular words identified as representing anger, dislike, fear, joy, sadness and surprise.
They found that almost all of the categories (类别) showed a drop in these “mood words” over time. Only in the category of fear was there an increase in usage.
“It is a steady and continuous decrease,” said Dr Alberto Acerbi. He assumed that the result might be explained by a change in the position occupied by literature, in a crowded media landscape. “One thing could be that in parallel to books the 20th century saw the start of other media. Maybe these media—movies, radio, drama—had more emotional content than books.”
Although both joy and sadness followed the general downwards trend, the research, published in the journal PLOS One, found that they also exhibited another interesting behaviour：the ratio (比率) between the two varied greatly, apparently mirroring historical events.
During the Roaring Twenties the joy-to-sadness ratio reached a peak that would not occur again until before the recent financial crash. But the ratio plunged at the height of the Second World War. Nevertheless, the researchers held a reserved opinion about their claim that their result reflected wider social trends. In the paper, they even argue that the reverse could be true.
“It has been suggested, for example, that it was the suppression (压抑) of desire in ordinary Elizabethan English life that increased demand for writing ‘filled with romance and sex’… perhaps,” they conclude, “songs and books may not reflect the real population any more than catwalk models reflect the average body.”
