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?

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.

Only about 30 percent of people in the US know how to perform CPR (心肺复苏术). Recently, a 9-year-old boy showed a Georgia woman how to perform CPR on her newborn baby.

Susanna Rohm said she had experienced a parent’s worst nightmare (噩梦) — her 2-month-old son, Isiah, was not breathing. “I noticed he looked pale. I looked at his arms and his legs and they were limp (无力的),” Rohm told a local newspaper. “Then I noticed that he looked like he wasn’t alive.” Indismay, she dropped and broke her cellphone. Rohm had to run into the street, screaming for help.

“I had him in my arms and screamed over and over. Then I ran outside. I saw two boys playing across the street, and I yelled, ‘Go and ask your parents to call 911,’” Rohm said. But the two boys were able to do more than that. Nine-year-old Ethan Wilson took action, showing Rohm how to perform CPR on little Isiah while ten-year-old Rocky Hurt helped as well.

Rocky said he had learned the CPR technique from a poster in a health class at their school, Sedalia Park Elementary. “I was thinking we’d better give her a helping hand instead of getting scared,” Ethan said. “I told her to push on the baby’s chest five to ten times a minute with only two fingers, tilt back the baby’s head, plug the baby’s nose and breathe into the baby’s mouth,” Ethan said in an interview.

At last, Isiah began crying and was breathing again. He spent two nights in a local hospital. “If the little boy hadn’t shown me what to do right there, my baby would probably not be alive right now,” Rohm said.

Although similar in appearance to hyenas(土狼), African wild dogs are nevertheless true wild canine(犬). They are a mixture of black, yellow, and white in such a wide variety of patterns that no two individuals look exactly alike. African wild dogs are widely distributed across the African plains but they do not live in jungle areas.

They are social animals, living in groups of usually from 2 to 45 individuals. A hierarchy（统团） exists within the group,　 but the animals are friendly to one another. The young and the infirm（体弱的） are given special privileges within the group.

African wild dogs use their sense of sight, not smell, to find their prey. They can run up to 55 km/h for several kilometers. In eastern Africa, they mostly hunt Thomson's gazelles, but they will also attack calves, warthogs, zebras, impalas, and the young of large antelopes such as the gnu.

Growing human populations have decreased or degraded the African wild dog's habitat and also diminished their available prey. Road kill and human persecution（迫害） have also had a negative impact on African wild dog populations. This species is also susceptible to a variety of diseases such as distemper, which is controlled in domestic .dogs.
