单选题Life on land probably began about 430 million years ago, though it has existed in the water for perhaps as long as 3, 000 mil lion years. When we think of the first life on land, we probably think of strange animals coming out of the oceans, but, in fact, no animals could have been living if plants had not been on land first. Plants had to be on land before animals arrived. They supplied the first land animals with food necessary to live, since they are the only form of life that is able to get and store energy. The first plants to exist out of the water were probably certain kinds of algae(海藻) which were followed by other plants that grew close to the ground near water and needed water in which to repro duce. Once the move to land had been made, however, evolution (进化) took place quickly. By the end of 100 million years, plants had developed their roots, and some developed tall tree like forms, since height was very important in competing for sunlight. About 300 million years ago, much of the world was covered with forests of huge trees. In most ways they were like modern trees. They had roots, leaves, wood, but mostly they had not developed seeds.

单选题Questions 11 to 15 are based on the following passage: We use both words and gestures to express our feelings, but the problem is that these words and gestures can be understood in different ways. It is true that a smile means the same thing in any language. So does laughter or crying. There are also a number of striking similarities in the way different animals show the same feelings. Dogs, tigers and humans, for example, often show their teeth when they are angry. This is probably because they are born with those behavior patterns. Fear is another emotion that is shown in much the same way all over the world. (80) In Chinese and in English literature, a phrase like "he went pale and begin to tremble" suggests that the man is either very afraid or he has just got a very big shock. However, "he opened his eyes wide" is used to suggest anger in Chinese whereas in English it means surprise. In Chinese "surprise" can be described in a phrase like "they stretched out their tongues!" Sticking out your tongue in English is an insulting gesture or expresses strong dislike. Even in the same culture, people differ in ability to understand and express feelings. Experiments in America have shown that women are usually better than men at recognizing fear, anger, love and happiness on people's faces. Other studies show that older people usually find it easier to recognize or understand body language than younger people do.
