题目内容
Do you know why different animals or pests (昆虫) 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(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 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 (猎人). This is because they have the colors much like the trees.
Have you ever noticed an even stranger act? 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 over (散开), its enemies (敌人)cannot find it. And it immediately swims away. So it has lived up to now though it is not strong at all.

阳光课堂同步练习系列答案If you want to keep healthy, you should have good habits. What is a habit? It is something we do very often. We don’t even think when we do it. It has become a part of our lives.
“Early to bed, early to rise makes a man healthy, wealthy and wise.” This is an old English saying. Do you know what it means? It means that we must go to bed early at night and get up early in the morning. If we do, we shall be healthy, rich and clever.
Is this true? Perhaps it is. We know the body must have enough sleep. Boys and girls need eight or nine hours’ sleep every day.
Some people go to bed late at night and get up late in the morning. This is a very bad habit. Then you will not think or do your work well. Of course, you can’t be healthy, wealthy or wise.
When we get up early in the morning, we can go out and do morning exercises. Exercise means doing things with the body. Walking, running jumping, swimming, and playing ball games are all exercise. If we don’t exercise, our body will become weak.
Exercise helps the blood (血液) to move around inside our body. Blood takes food to all parts of our body.
Our body also needs air to breathe. Without air, we will die. We must have lots of clean fresh air if we want to be healthy. That is why many people like to go out to do morning exercise.

Do you know soon eleven biggest food and drink companies of the nations will adopt new rules to limit advertising to children under the age of 12, a move that restricts ads for products such as McDonald’s Happy Meals and the use of popular cartoon characters.
The companies announced their new rules ahead of a Federal Trade Commission hearing on Wednesday that steps up pressure on the companies to help solve the growing child obesity problem through more responsible marketing. The self-given rules include promises by seven companies who will no longer use licensed characters, such as those made popular through movies or TV shows, to advertise online or in print media unless they’re promoting their healthier products. Four other companies said they do not advertise at all to children under 12.
“I think this is a very good step forward. It’s not the end of the journey but it’s a good way down the road,” said Margo Wootan, Nutrition Policy Director at the nonprofit Center for Science in the Public Interest.
Since the FTC first publicly raised the issue in 2005, many of the companies have started selling products with better nutrition in mind. The companies hope their self-regulation efforts — organized through the Council of Better Business Bureaus — will fend off any new and more strict federal regulation.
Parents are happy to see new rules that restrict the use of cartoon characters such as Shrek, Dora the Explorer and SpongeBob SquarePants. “It catches their eyes when you’re shopping,” said Josephine Thomas, a mother of three boys who lives in Manhattan. “As soon as they see a Shrek or Mickey Mouse, they automatically look at that and they don’t see what they really need. That’s one of the biggest problems when you go shopping.” That’s one reason the food companies have said they will now only use licensed characters to advertise their “better for you” products.
