It is only during the last few years that man has generally realized that in the world of nature a balance exists between all forms of life. No living thing can exist by itself. It is part of a system in which all forms of life are joined together. If we change one part of the nature order, this will almost certainly bring about changes in some other parts.

　　The cutting of forests reduced the supply of oxygen. The killing of weeds and insects by chemicals led to the wide-spread poisoning of animals and birds. The throwing of waste products into the ocean hurt life in the sea, while waste gases changed the chemical balance of the atmosphere and shut out some of the sun’s necessary life-giving rays.

　　And so we could go on adding more examples until in despair(绝望) we might feel like giving up the struggle to control these harmful human activities. Man is very clever at changing the world around him to satisfy his immediate needs, but he is not so clever at looking far ahead, or at thinking about what the future results of his action might be. Man may well destroy himself because of his silly action.

1.The first paragraph tells us that _____.

2.In the second paragraph the examples given are used to prove that _____.

3.The last paragraph suggests that in order to get his immediate benefits(利益) _____.

4.Which of the following is true according to the passage?

Being a mother is apparently not like it was in the good old days.
　　Today’s parents yearn for the golden age that their own mothers enjoyed in the 1970s and 1980s, researchers found. Mothers have less time to themselves and feel under greater pressure to handle work and family life than the previous generation. As a result, 88 per cent said they felt guilty about the lack of time they spent with their children.
The survey of 1,000 mothers also found that more than a third said they had less time to themselves than their mothers did – just three hours a week or 26 minutes a day. And 64 per cent said this was because they felt they ‘had’ to go out to work, while nearly a third (29 per cent) said they were under constant pressure to be the ‘perfect mother’, the report found.
Other findings showed social networking and parenting websites, as well as technology such as Skype, were important in providing help and support among female communities. Kate Fox, a member of the Social Issues Research Centre, which conducted the survey for Procter & Gamble, said: ‘With increasing pressure on mothers to work a “double shift”— to be the perfect mother as well as a wage-earner — support networks are more important than ever.
It comes as a separate report examining childcare in the leading industrialised nations found that working mothers in Britain spend just 81 minutes a day caring for their children as a ‘primary activity’. Mothers who stay at home, on the other hand, manage twice as much time – more than two and a half hours – looking after their offspring, according to the Organisation for Economic Co-operation and Development.
　　Critics say the pressure on women to work long hours, and leave their offspring in the hands of nurseries or childminders, is putting the well-being of their children at risk.
　　The study also reveals that, despite the fact that more and more modern mothers go out to work, the burden of childcare still falls on them - even if their husband is not in work. A father who is not in work tends to spend just 63 minutes a day looking after his child - 18 minutes less than a mother who goes out to work. Working fathers spare less than three quarters of an hour with their children.

One morning a few years ago，Harvard President Neil Rudenstine overslept. For this busy man，it was a sort of alarm: after years of non-stop hard work，he might wear himself out and die an early death.
Only after a week's leave—during which he read novels, listened to music and walked with his wife on a beach—was Rudenstine able to return to work.
In our modern life, we have lost the rhythm between action and rest. Surprisingly, within this world there is a universal but silly saying:“I am so busy.”
We say this to one another as if our tireless efforts were a talent by nature and an ability to successfully deal with stress. The busier we are, the more important we seem to ourselves and, we imagine, to others. To be unavailable to our friends and family, and to be unable to find time to relax—this has become the model of a successful life.
Because we do not rest, we lose our way. We miss the guide telling us where to go, the food providing us with strength, the quiet giving us wisdom.
How have we allowed this to happen? I believe it is this: we have forgotten the Sabbath, the day of the week—for followers of some religions—for rest and praying. It is a day when we are not supposed to work, a time when we devote ourselves to enjoying and celebrating what is beautiful. It is a good time to bless our children and loved ones, give thanks, share meals，walk and sleep. It is a time for us to take a rest, to put our work aside, trusting that there are larger forces at work taking care of the world.
Rest is a spiritual and biological need；however，in our strong ambition to be successful and care for our many responsibilities，we may feel terribly guilty when we take time to rest. The Sabbath gives us permission to stop work. In fact, “Remember the Sabbath ”is more than simply permission to rest；it is a rule to obey and a principle to follow.
50. The “alarm” in the first paragraph refers to “______”.
　　A. a signal of stress                                  B. a warning of danger
　　C. a sign of age                                      D. a spread of disease
51. According to Paragraph 4,a successful person is one who is believed to ____.
　　A. be able to work without stress　　            B. be more talented than other people
　　C. be more important than anyone else　　 D. be busy working without time to rest
52. Some people feel guilty when taking time to rest because they ____.
　　A. think that taking a rest means lacking ambitions
　　B. fail to realize that rest is an essential part of life
　　C. fail to realize that religions force them to rest
　　D. think that taking a rest means being lazy
53. What is the main idea of this passage?
　　A. We should balance work with rest.
　　B. The Sabbath givers us permission to rest.
　　C. It is silly for anyone to say “I am so busy.”
　　D. We should be available to our family and friends.

　　Forests have always been useful and important to man who makes use of them in many ways. Every day trees are serving man everywhere. Trees supply man with fruits and building materials in the form of wood. Without trees it would be impossible to build houses, boats, bridges and so on. Furniture such as desks, chairs and beds is made of wood. Trees can stop man from terrible heat. They're also useful in preventing good and rich top soil from being washed away during heavy rains.

　　If there were no trees, heavy rains would wash away the rich top soil that is so important to plants. The result is that the land will become a desert. There are plenty of desert areas in the world. A long time ago these desert areas used to be very rich areas, but man in the past had no enough knowledge about science of nature, they cut down too many trees in the area where they lived and never planted new ones. By and by the rich top soil was blown and washed away by strong winds and heavy rains. In the end the rich land changed into useless deserts where nothing could grow.

　　　　D. people have always found trees useful

　　If there were no trees, ______.

　　　　A. the land would become better　　　　B. heavy rains would be very clean
