听力原文： As is known to all, scientists and philosophers had studied the human body and its functions from very early times. Unfortunately, many of the ideas and theories, correct and incorrect, were accepted without question for a great number of years. But by the 16th century, knowledge gained through chemical experiments was beginning to make some people think more deeply about how the human body works.
A most important medical discovery was made by William Harvey in 1628. He found out that the blood is circulated round the body in one direction only by the pumping action of the heart. It had previously been incorrectly thought that the blood moved with a backward and forward motion.
Early in the 17th century a new instrument came into use that was to open up a whole new area in the study of medical and scientific matters. This was the microscope.
The first instruments were not very efficient. They were able to magnify only a very small part of the object and this was always surrounded by rings of colored light. Nevertheless a great step forward had been taken which was of vital importance for future research and development.

A．Scientists and philosophers had never studied the human body and its functions.
B．Many of the ideas and theories that people used to accept were all incorrect.
C．People used to accept ideas and theories.
D．People used to accept undoubtedly many of the ideas and theories, correct and incorrect.

What reason is there to think that we may actually detect intelligent life in outer space？ To begin with, modern theories of the development of stars suggest that almost every star has some sort of family of planets. So any star like our own sun (and there are billions of such stars in the universe) is likely to have a planet situated at such a distance that it would receive about the same amount of radiation as the earth.
Furthermore, such a planet would probably have the same general composition as our own; so, allowing a billion years or two--or three--there would be a very good chances for life to develop, if current theories of the origin of life are correct.
But intelligent life7 Life that has reached the stage of being able to send radio waves out into space in a conscious pattern7 Our own planet may have been in existence for five billion years and may have had life on it for two billion, but it is only in the last fifty years that we are capable of sending radio waves into space. From this it might seem that even if there were no technical problems involved, the chance of receiving signals from another planet would be extremely small.
This does not mean that intelligent life at our level does not exist somewhere. There are such an unimaginable number of stars that, even at such miserable odds, it seems certain that there are millions of intelligent life forms scattered through space. The only trouble is, none may be within our reach. Perhaps none never will be; perhaps the distances that separate us from our fellow inhabitants of this universe will forever remain too great to be conquered. And yet it is conceivable that someday we may come across one of them or one of them may come across us. What would they be like, these extraterrestrial(地球以外的) creatures？
If the radio waves had reached our planet one hundred years before, we would have______.
A．sent an immediate answer
B．sent an alarm against extraterrestrial attack
C．sent a short reply
D．sent no answer

第10题
As the society became more complicated, the status of children in the family and in the society became more important. In the complex, technological society that the United States has become, each member must fulfill a number of personal and occupational roles and be in constant contact with a great many other members. Consequently, viewing children as potentially acceptable and necessarily multifaceted members of society means that they are regarded more as people in their own fight than as utilitarian organisms. This acceptance of children as equal participants in the contemporary family is reflected in the variety of statutes protecting the rights of children and in the social and public welfare programs devoted especially to their well-being.
This new view of children and the increasing contact between the members of society has also resulted in a surge(激增) of interest in child-rearing techniques. People today spend a considerable portion of their time consulting the proper way to bring up children. It is now possible to affect the details of the socialization of another person's child by spreading the gospel (信条) of current and fashionable theories and methods of child rearing.
The socialization of the contemporary child in the United States is a two-way communication between parent and child rather than a one-way, parent-to-child training program. As a consequence, socializing children and living with them over a long period of time is for parents a mixture of pleasure, satisfaction, and problems.
It can be inferred about formal schooling in colonial North America that______.
A．it was generally required by law
B．it was considered relatively unimportant
C．it was highly disciplined
D．it was improperly administered
