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 a part of a system (体系) in which all forms of life are joined together. If we change one part of the natural order, this will in its turn almost certainly bring about changes in some other part.

The cutting down of forests reduces the supply of oxygen. The killing of weeds and insects by chemicals leads to the wide spread poisoning of animals and birds. The throwing of waste products into the ocean harm to life in the sea, while waste gases change the chemical balance of the atmosphere.

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

Of the thousands of different kinds of animals that exist in the world man has learned to make friends with an enormous number. Some are pets, and offer him companionship; some give protection, and some do hard work which man cannot do for himself. Dogs, which serve man in all three capacities, are found in various species in all countries of the world. The Husky can live in the cold polar regions, and the Saluki is at home in the hottest parts of Central Africa. The inhabitants of certain countries are dependent for their very lives on the camel. In the West Indies the little donkey, strong and sure-footed, carrying heavy loads even in mountainous places, is a familiar sight.

Trained and tamed for many generations, domestic animals are not accustomed to roaming in search of food and shelter. They look to their masters to provide for their needs, and as long as these are supplied, they are content to do what their masters require.

  All domestic animals need proper food. It must be suitable for them, sufficient inquantity, fresh and clean. Some people feed a pet dog or cat on odds and ends of table scraps(剩饭), and then wonder why the animal seems tired and dull. The quantity of food depends on the size of the animal and the amount of exercise it takes. Overfeeding is as bad as underfeeding. Containers for food and water must be washed regularly if the animal is to maintain good health.

Even well-cared-for animals may sometimes fall ill. If this happens, the wise master seeks the best advice he can get. All sorts of medicines and treatments are available for sick animals, and in some countries organizations exist to provide them free or at a cheap price. Useful, friendly, hardworking animals deserve to have some time, money and attention spent on their health.

If you are a 30-plus plain Jane, or if you are not a local fresh graduate, get ready for the embarrassment(尴尬) in the job market. And you are just one of the millions to face discrimination（歧视）.
About 85 percent of the 3,424 people covered by a survey in 10 big cities, including Beijing and Shanghai, said discrimination in work and employment（就业） did exist. Also, the survey results given on Friday showed that 58 percent thought the problem to be severe（严重）.
Appearance, height and gender are the most discriminative categories（范畴）, the Beijing Morning Post reported.
Some requirements could be funny. The newspaper said Beijing citizen Zhang Meng, who had more than 10 years’ driving experience, failed to get a job because his possible employers considered his name to be “unlucky”.
“Meng”, they said, literally(字面上)means “rush” in Chinese, which made him more accident prone（倾向）than others.
Employers discriminate against people from certain regions or areas, such as Central China’s Henan Province, because of the bad impression they have about them. Beijing citizens, too, have their share of bad luck because they are generally considered lazy.
Cai Dingjian, a professor from China University of Political Science and Law, who headed the survey, said such requirements, which are not connected with the job itself, violate（侵犯）people’s equal right to look for a career. “It violates basic human rights,” he said to the newspaper.
Cai said governments should pay attention to such discriminations because they exist not only in companies, but are also practiced by them. One example is that civil servants(公务员) are usually required to have a pleasant personality.
Director of the labour law committee under the All China Lawyers Association
Jiang Junlu said the lack of related laws was at the root of all discriminations.
46. Zhang Meng failed to get a job because __________.
A. he had made more mistakes than others

D. he couldn’t find a pleasant employer
47. What is people’s response to discrimination in job market?
A. They think it is unfair but necessary due to the large population of China.
B. It does exist in certain regions, but is not so serious.
C. Something must be done to stop it by governments.
D. It is a local problem and isn’t worth much concern.
48. What can be an effective way to fight against discrimination according to the passage?
A. To fine companies which practice discrimination.
B. To make laws related to discrimination.
C. To stop more people moving into cities.
D. To train people those who are poor in skills.
49. Which of the following is NOT true according to the passage?
A. Discrimination not only exists in companies, but also in governments.
B. Employers nowadays concern more about appearance, height and gender.
C. People in Beijing will never worry about experiencing discrimination.
D. Requirements connected with the job itself should have been put in the first place.

Why should mankind explore space? Why should money, time and effort be spent exploring and researching something with so few apparent benefits? Why should resources be spent on space rather than on conditions and people on Earth? These are questions that, understandably, are very often asked．
Perhaps the best answer lies in our genetic makeup（基因构成）as human beings．What drove our ancestors to move from the trees into the plains, and on into all possible areas and environments? The wider the spread of a species, the better its chance of survival．Perhaps the best reason for exploring space is this genetic tendency to expand wherever possible．
Nearly every successful civilization has explored, because by doing so, any dangers in surrounding areas can be identified and prepared for．Without knowledge, we may be completely destroyed by the danger．With knowledge, we can lessen its effects．
Exploration also allows minerals and other potential （潜在的）resources to be found．Even if we have no immediate need of them, they will perhaps be useful later．Resources may be more than physical possessions．Knowledge or techniques have been acquired through exploration．The techniques may have medical applications which can improve the length or quality of our lives．We have already benefited from other spin-offs including improvements in earthquake prediction, in satellites for weather forecasting and in communications systems．Even non-stick pans and mirrored sunglasses are by-products （副产品）of technological developments in the space industry!
While many resources are spent on what seems a small return, the exploration of space allows creative, brave and intelligent members of our species to focus on what may serve to save us．While space may hold many wonders and explanations of how the universe was formed or how it works, it also holds dangers．The danger exists, but knowledge can help human being to survive．Without the ability to reach out across space, the chance to save ourselves might not exist．
While Earth is the only planet known to support life, surely the adaptive ability of humans would allow us to live on other planets．It is true that the lifestyle would be different, but human life and cultures have adapted in the past and surely could in the future．
【小题1】Why does the author mention the questions in Paragraph1?

Humans are naturally drawn to other life forms and the worlds outside of our own. We take delight in the existence of creatures and even whole socicties beyond our everyday lives.

This sense of wonder is universal look at the efforts that scientists have made to find out whether life of some kind exists on Mars, and the popularity of fantasy(幻想) litcrature or movies like The lord of the Rings, This sense of wonder drous us to each other, to the world around us, and to the world of make-believe.
