Passage Three
Everyone knows the small insects called mosquito. It is possible to find mosquitoes in almost every part of the world except in the places where it is extremely cold or where it is very dry. During the summer, it is almost certain that you can find many mosquitoes near swamps (沼泽), ponds, and lakes.
Mosquitoes have an interesting life cycle. The female mosquito bites a person or animal in order to get some blood. She needs this blood before she can lay her eggs. Second, she flies to an area of water and deposits (存放),40 her eggs in the water. In a few days the eggs open, and the baby mosquitoes, called larvae, come out. In a short time, they will be mature and fly away.
It is interesting to note that only the female will bite for blood. She has a special mouth which can go into an animal’s skin or a person’s skin. On the other hand, the male mosquito can only drink plant juices with his mouth.
Text 3
As everyone knows, words constantly take on new meanings. Since they do not necessarily, nor even usually, take the place of the old ones, we should picture this process as the analogy of a tree throwing out new branches which themselves throw out subordinate branches. The new branches sometimes overshadow and kill the old one but by no means always. We shall again and again find the earliest senses of a word flourishing for centuries despite a vast overgrowth of later senses which might be expected to kill them.
When a word has several meanings historical circumstances often make one of them dominantduring a particular period. Thus "station" is now more likely to mean a railway-station than anything else; "speculation" more likely to bear its financial sense than any other. Until this century "plane" had as its dominant meaning "a flat surface" or "a carpenter’s tool to make a surface smooth",
A. stress the natural phenomena
B. picture the process of growth of new branches
C. explain what the analogy is
D. illustrate his view in a clearer way
