1 How much living space does a person need? What happens when his space requirements are not adequately met? Sociologists and psychologists are conducting experiments on rats to try to determine the effects of overcrowded conditions on man. Recent studies have shown that the behavior of rats is greatly affected by space. If rats have adequate living space, they eat well, sleep well, and reproduce well. However, if their living conditions become too crowded, their behavior patterns and even their health perceptibly change. They cannot sleep and eat well, and signs of fear and tension become obvious. The more crowed they are, the more they tend to bite each other and even kill each other. Thus for rats, population and violence are directly related. Is this a natural law for human society as well? Is adequate space not only desirable, but essential for human survival? 1. This

while the others follow their example. Let's say the top crowd decides
that it is smart to wear bright red sweaters(运动衫). Pretty soon
everybody is wearing bright red sweaters. There is nothing wrong with
that, except the fact that for some people bright red is rather
unsuitable. The suitable can even become dangerous, if the top crowd
decides that it is smart to drink or to drive cars at seventy miles an
hour. Then the people who follow the example are endangering their
very lives. They are like sheep being led to the slaughter(屠宰). 11.

around other babies than with strange adults. According to the study,

baby might show fear of an adult stranger, he is likely to smile and
reach out for an unfamiliar infant. By the time babies are one year
old, they have begun to form friendships of a sort. 16. What

likely to feel more at ease with _________. 18. What does Dr.

The author is talking to _________. 5 In 1752, three years after two Scotsmen, Alexander Wilson and Thomas Melville, fastened thermometers to kites to record the temperature of clouds, Benjamin Franklin made his famous experiment with a kite, a string, and a key. Franklin hoped to show that nature's tremendous displays of electricity in lightning were the same thing as the feeble electric sparks scientists of the day were producing in their laboratories. He built a square kite to which he attached an iron wire. He flew the kite with a hemp string(麻线), and near the base of the string he tied a large brass key. The kite rose into a dark thundercloud, where the iron wire picked up electrical charges. Franklin noticed that the strands of the string(绳串) were beginning to stand up with electricity. As rain wet the string, it conducted more electricity. Standing in the shelter of a shed, Franklin cautiously reached out his finger to touch the brass key. A series of sparks jumped from the key to his finger. He thus proved that lightning and electricity are the same. We now know that this experiment was a dangerous one, for Franklin might have been killed by a bolt of lighting. 21. The best title for
this passage is ________. 22.
