20．判断阅读下面的材料，判断下列句子是否符合短文内容．符合的涂T，不符合的涂F．
（T=True，F=False）
What is color？Why do some of the things around us look red，some green，others blue？
Colors are really made by reflected（反射） light．We can see colors because most of the things reflect light．Something is red，for it reflects most of the red light．In the same way，if something is green，it reflects most of the green light．If something reflects all light，it is white．If it doesn't reflect any light，it is black．
Some light is reflected．But the other light is taken in and turns into heat．The darker the color is，the less light is reflected，and the more light is taken in．For this reason，dark-colored clothes are warmer in the sun than light-colored clothes．

2．Everyone knows that chickens lay eggs（产卵）．Most people know that all the other birds do as well．But have you ever thought about other animals that lay eggs？They include bees，snakes and some sea animals．
When a mother lays eggs，many more babies can be born at once，or in a few days，because there is very little development inside the parent．Animals that do not lay eggs often have fewer babies．Animals lay many eggs because other animals may eat the babies．However，even though some of their babies are eaten，they will still have some more to continue their family．
Some animals that lay eggs do not take care of their young．Turtles come on to the beach and dig（挖）holes．Then they put their eggs in the sand and leave．A turtle mother can lay as many as 150eggs．When the babies come out of the eggs，they must find their own way to the ocean．They must learn how to live on their own．Many young turtles get eaten by other animals．
Most eggs have an outside shell（壳）that keeps the growing animal inside safe．The egg shell also keeps the young animal from drying out．After the animal is fully developed，it comes out of the egg．
The animal grows bigger and bigger．Then it can have its own young．

3．Expressions cover all parts of our life．They may be around your ears every day．You may know a lot of Chinese expressions that describe how you feel．Here are some English ones for your enjoyment．

Have Butterflies in the Stomach
How did butterflies get in your stomach？Well，those really aren't butterflies in there．It is a way of describing those nervous feelings you might get before a test or a very important decision．
These stomach flutters（跳动） are normal and happen to many people．Some people believe having a few butterflies might even help you perform better．
