　　106. Animal research is irrelevant to our health and it can often produce misleading results.

　　107. It would be completely irresponsible and unethical to use drugs on people that had not been thoroughly tested on animals.

　　108. If thalidomide were invented today， it would never be released for human use because new tests on pregnant animals would reveal the dangers.

　　109. The number of animals used in laboratory tests has declined over the last 20 years

　　110. One experiment in nerve regeneration involves cutting a big nerve in a rat‘s leg， leaving its leg paralysed.

　　111. Even with these new developments in research， only a tiny proportion of all tests are done without using animals at some stage.

　　112. The use of animals in experiments cannot stop immediately if medical research is to continue and consumer products are to be properly tested.

　　113. When it comes to research into heart disease and its effects on the body， we do not have adequate substitutes for the use of animals.

　　114. As research techniques become more advanced， the number of animals used in experiments may decrease， but stopping testing on animals altogether is a long way away.

　　115. I was surprised to see his room in such a litter.

　　116. The conditions that existed ten years ago are reproduced today.

　　Unit 12

　　117. Until recently daydreaming was generally considered either a waste of time or a symptom of neurotic tendencies.

　　118. At its best， daydreaming was considered a compensatory substitute for the real things in life.

　　119. As with anything carried to excess， daydreaming can be harmful.

　　120. There is a growing body of evidence to support the fact that most people suffer from a lack of daydreaming rather than an excess of it.

　　121. Daydreaming significantly contributes to intellectual growth， power of concentration， and the ability to interact and communicate with others.

　　122. Daydreaming resulted in improved self-control and enhanced creative thinking ability.

　　123. Contrary to popular belief， constant and conscious effort at solving a problem is， in reality， one of the most inefficient ways of coping with it.

　　124. Whenever confronted with a task which seemed too hard to be dealt with， he would stretch out on his laboratory sofa and let fantasies flood his mind.

　　125. The important thing to remember is to picture these desired objectives as if you had already attained them.

　　126. Daydreaming is highly beneficial to your physical and mental well-being.

　　127. Escape being impossible， the rabbit turned to confront the dog.

　　128. The difficulties that confront us cannot be overcome.

　　Unit 13

　　129. He cannot be really happy if he is compelled by society to do what he does not enjoy doing， or if what he enjoys doing is ignored by society as of no value or importance.

　　130. In a society where slavery in the strict sense has been abolished， the sign that what a man does is of social value is that he is paid money to do it.

　　131. What from the point of view of society is necessary labor is from his own point of view voluntary play.

　　132. Whether a job is to be classified as labor or work depends， not on the job itself， but on the tastes of the individual who undertakes it.

　　133. It is already possible to imagine a society in which the majority of the population， that is to say， its laborers， will have almost as much leisure as in earlier times was enjoyed by the aristocracy.

　　134. The masses are more likely to replace an unchanging ritual by fashion which it will be in the economic interest of certain people to change as often as possible.

　　135. Workers seldom commit acts of violence， because they can put their aggression into their work， be it physical like the work of a smith， or mental like the work of a scientist or an artist.

　　136. They were often compelled to work twelve or fourteen hours a day.

　　137. The police undertook detailed and comprehensive investigations into the case.

　　Unit 14

　　138. The device， though， would do much more than capture a lecture.

　　139. It was a microcassette found in Kathleen Weinstein‘s shirt pocket that not only led police to her alleged killer but also revealed the New Jersey teacher to be a woman of extraordinary courage and compassion.

　　140. Grabbing Weinstein by the jaw， the attacker told her he had a gun and forced her into the Camry.

　　141. It was there， police believe， that Weinstein was able to activate the recorder she kept in her bag.

　　142. Her power of persuasion were to no avail.

　　143. Weinstein‘s body， with hands and feet bound， was discovered by a hiker on March 144. Given her fate， the name of the program has a heartbreaking resonance to it：

　　Random Acts of Kindness.

　　145. The operation fostered hope in the patient.

　　146. We protested but to no avail.

　　147. He was firmly convinced that risk accompanies decisions.

　　Unit 15

　　148. The computer makes possible a marvellous leap in human proficiency.

　　149. But the question persists and indeed grows whether the computer will make it easier or harder for human beings to know who they really are…。

　　150. There may be a tendency to mistake data for wisdom， just as there has always been a tendency to confuse logic with values， and intelligence with insight.

　　151. To the extent， then， that man fail to distinguish between the intermediate operations of electronic intelligence and the ultimate responsibilities of human decision， the computer could prove a digression.

　　152. It may promote undue confidence in concrete answers.

　　153. …before we lose ourselves in celebrating the victory， we might reflect on the great advances in the human situation that have come about because men were challenged by error and would not stop thinking and exploring until they found better approaches for dealing with it.

　　154. For the danger is not so much that man will be controlled by the computer as that he may imitate it.

　　155. Even to speculate on it is a gain.
