[单项选择]The baby monkey is much more developed at birth than the human baby. Almost from the moment it is born, the baby monkey can move around and hold tightly to its mother. During the first few days of its life the baby will approach and hold onto almost any large, warm, and soft object in its environment, particularly if that object also gives it milk. After a week or so, however, the baby monkey begins to avoid newcomers and focuses its attentions on “mother”—the real mother or the mother-substitute (母亲替代物).
During the first two weeks of its life warmth is perhaps the most important psychological thing that a monkey mother has to give to its baby. The Harlows, a couple who are both psychologists, discovered this fact by offering baby monkeys a choice of two types of mother-substitutes—one covered with cloth and one made of bare wire. If the two artificial mothers were both the same temperature, the little monkeys always preferred the cloth mother. However, if the wire model was hea

[填空题]Most theories about the evolution of Earth have the same general point of view.
[单项选择]Do you know why different animals or pests have their special colors Colors in them seem to be used mainly to protect themselves.
Some birds like eating locusts(蝗虫), but birds cannot easily catch them. Why It is because locusts change their colors together with the change of the colors of crops. When crops are green, locusts look green. But as the harvest time comes, locusts change to the same brown color as crops have. Some other pests with different colors from plants are easily found and eaten by others. So they have to hide themselves for lives and appear only at night.
If you study the animal life, you’ll find the main use of coloring is to protect themselves. Bears, lions and other animals move quietly through forests. They cannot be easily seen by hunters. This is because they have the colors much like the trees.

Drivers on the Basingstoke by-pass used to have their attention diverted by a sign that reads A MOMENT’S INATTENTION CAUSES ACCIDENTS. This self-defeating warning has now been removed, but its message is still very much to the point.
Almost anything can cause an accident. Apart from momentary inattention, it might be a minor miscalculation, a sudden fit of coughing, a bop on the head with a teddy-bear from a child in the back seat, an argument with the wife, fog, falling asleep at the wheel, bad eyesight, a glaring sun, ice, rain, wind, or snow-all these can make the difference between a tragic hit and a lucky miss.
Although human error plays its part, it is by no means the only cause of accidents. There must be some cause other than simple human error. Road construction plays its part: researchers have found that it is not at the obvious danger spot- sharp corners, cross-roads, narrow lanes — that accidents happen. It is on those roads where there are
A. you have been injured by somebody
B. your car has been damaged
C. you have injured somebody else
D. you have witnessed the accident
