They move for different reasons: most of them move to find food more easily, but others move to get away from places that are too crowded.When cold weather comes, many birds move to warmer places to find food. Some fishes give birth in warm water and move to cold water to feed. The most famous migration（迁移）is probably the migration of the fish, which is called "salmon". This fish is born in fresh water but ittravels many miles to salt water. There it spends its life. When it is old, it returns to its birth place in fresh water. Then it gives birth and dies. In northern Europe, there is a kind of mouse. They leave their mountain homes when they become too crowded. They move down to the low land. Sometimes they move all the way to the seaside, and many of them are killed when they fall into the sea.Recently, scientists have studied the migration of a kind of lobster (龙虾). Every year, when the season of the bad weather arrives, the lobsters get into a long line and start to walk across the floor of the ocean. Nobody knows why they do this, and nobody knows where they go.So, sometimes we know why humans and animals move from one place to another, but at other times we don’t. Maybe living things just like to travel.1.

But a few months ago, he became a college student in Lishan College in Shandong and he studies math there now. When hearing this news, many people were surprised. On school opening day, many reporters waited outside the school gate to interview him.“I was born in a poor village in Shandong Province," said Jia. "Our village has never had a college student.

No, according to the UN World Food Program, there were 925million hungry people around the world in 2010, especially in developing countries. Six million children die of hunger every year.Chinese people are well known for being generous (慷慨的）. Many even feel that they lose face if their guests have eaten all the food on the table.Luckily, a number of people have realized the importance of saving food. Last November, Li Hong, a waitress in a restaurant in Nanjing, got fired（开除）because she took some leftover（剩余的）food home for her son. Many people stood by her side and agreed that it was not right to waste food.What should we do in our daily life to waste less food? Here are some tips:◆Do not order too much in a restaurant. Only order what you want to eat. If you cannot eat all the food you ordered, take the rest of it home.◆Don't be too picky（挑剔的）about food. Some food may not taste great. But your body needs it.◆Keep an eye on what food you have at home. Don't buy too much, especially for vegetables and fruit.11.
