第4题：

In spite of all stories of prosperity in the Unites States, not only does poverty exist there, but crimes of various types have been increasing at an alarming rate. Most acts of violence were committed by young people.57% of the criminals arrested in 1979 were youths below 25 of age.
Everyone agrees that crime is partly a result of bad material conditions: poverty, lack of education, living within a settled home, being parent less, sufferings from other kinds of misfortune, etc.

Finally, there has been too much shown on TV and too much reported in newspaper of all kinds of crime, the details of which are so accurately described that even children know how to duplicate what they have seen or read. All these have resulted in a high frequency of crimes committed both by professional criminals and
by nonprofessional ones in murder, drug smuggling, robbery, etc.

Passage Two

Questions 26 to 30 are based on the following passage.

Scientists have established that influenza viruses taken from man can cause the disease in animals. In addition，man can catch the disease from animals. In fact，a great number of wild birds seem to carry the virus without showing any evidence of illness. Some scientists conclude that a large family of influenza viruses may have evolved in the bird kingdom，a group that has been on the earth 100 million years and is able to carry the virus without contracting the disease. These are even convincing evidence to show that virus strains are transmitted from place to place and from continent to continent by migrating birds.

It is known that two influenza viruses can recombine when both are present in an animal at the same time. The result of such recombinations is a great variety of strains constraining different H and N spikes. This raises the possibility that a human influenza virus can recombine with an influenza virus form. a lower animal to produce an entirely new spike.

Research is underway to determine if that is the way that major new strains come into being. Another possibility is that two animal influenza strains may recombine in a pig，for example，to produce a new strain which is transmitted to man.

According to the passage，scientists have discovered that influenza viruses______.

A. cause ill health in wild birds

B. do not always cause symptoms in birds

C. are rarely present in wild birds

D. change when transferred from animals to man
