Every object has weight. But the center of its weight is not always in the middle of the object. If the top of an object is heavier than its bottom, it will fall over easily. We say that its center of gravity(重力) is high. But if the bottom is heavier, it won"t fall easily. Then we say that its center of gravity is low. Look at the first picture. This empty box must fall over, because its center of gravity (C) is not above the line of its bottom (AB). Now look at the second picture. There are some heavy things in the bottom of this box. It will not fall, because its center of gravity is above its bottom. 1. Box _____________will not fall.. 2. The main idea of the passage is _________. A. why things fall over B. a low center of gravity C. a high center of gravity D. that everything has weight | |||

Do you know why different animals or pests (害虫) have their special colors?Colors on them seem to be used mainly (主要地) to protect themselves. Some birds like eating locusts (蝗虫), but birds cannot catch them easily. Why? Because locusts change their colors according to the colors of crops (庄稼). 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 (隐藏) themselves and appear (出现) only at night. If you study 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 (猎人). This is because they have colors much like the trees. A kind of fish in the sea can send out a kind of very black liquid (液体) when it faces danger. While the liquid spreads out, its enemies (敌人) cannot find it, so it can escape (逃跑) at once. That is why it can live long, though it is not strong at all. | |||
