We know that many animals do not stay in one place. Birds, fish and other animals move from one place to another at a certain time. 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 it travels many miles to salt water. There it spends its life. When it is old, it returns to its birthplace in fresh water. Then it gives birth and dies there. 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 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 time we don't. Maybe living things just like to travel.
(1)Most animals move from one place to another at a certain time to ________.
[ ]
(2)The fish called“salmon”spends a long life in ________.

(3)The mice in northern Europe move when ________.

B．The migration of the fish called“salmon”is the most famous migration.
C．Living things move from one place to another because they like to travel.
D．Sometimes we know why and how living things move from one place to another, but sometimes we don't.

When I come across a good article in reading newspapers, I often want to cut and keep it. But just as I am about to do so I find the article on the 1 side is as much interesting. It may be a discussion of the way to 2 in good health, or 3 about how to behave and conduct oneself in society. If I cut the front article, the opposite one is likely to 4 damage, leaving out half of it or keeping the text 5 the title. Therefore, the scissors(剪刀）would 6 before they start, 7 halfway done when I find out the 8 result.
Sometimes two things are to be done at the same time, both worth your 9 . You can only take up one of them, the other has to wait or be 10 up. But you know the future is unpredictable(不可预测的)—the changed situation may not allow you to do what is left 11 . Thus you are 12 in a difficult position and feel sad. How 13 that nice chances and brilliant ideas should gather around all at once? It may happen that your life 14 greatly on your preference of one choice to the other.
In fact that is what 15 is like: we are often 16 with the two opposite sides of the thing which are both desirable like a newspaper cutting. It often occurs that our attention is drawn to one thing only 17 we get into another. The 18 may be more important than the latter and give rise to a divided mind. I 19 remember a philosopher’s remarks: “When one door shuts, another opens in life. ”So a casual(随意的) 20 may not be a bad one.
