Plants and animals are largely made of water. So are humans. They need to keep enough water inside them, or they could die.

We get some of the water we need by eating food that has water in it. Drinks, such as milk and tea, are mostly water, too. A person needs water every day. If we go without water for three or four days, we will lose too much water from our bodies. In very hot weather, we could lose this water in just one day.

What does water do to help our bodies? Water helps to take the nutrition（营养）from food to our bodies. It also helps to take the wastes away from different parts of our bodies.

In our homes, we also need water for many things. We need water for cooking, washing and flushing（冲水）the toilet. About three quarters of the water is used in the bathroom and toilet. The rest is mainly used in the laundry（洗衣房）and kitchen.

___________It may come from a lake or a river. It may come from the sea, from the rain and snow or from the underground. Water rises from rivers and seas to make clouds, and then falls again as rain and snow. The water you drink has been around for millions of years. It just keeps being recycled.

Many people work hard to make sure we always have clean water in our homes. Water is very important for all living things, so we should use it carefully.

1.Living things could ___________ without enough water inside them.

A.grow B.die C.live D.develop

2.A person can get water that he needs by ___________.

A.taking wastes away B.losing water quickly

It's a common belief that fish can't remember anything for longer than seven seconds. It may seem sad to think that every moment in their lives would be like seeing the world for the first time. But don't be so quick to feel sorry for them. A new study has found that fish have much better memories than we used to think.

In the study, researchers from Mac Ewan University in Canada trained a kind of fish called African cichlids to go to a certain area of their tank to get food. They took the fish out and then waited for 12 days before putting them back in the tank again. They found that after such a long break the fish sill went to the same place where they first got food.

In fact, scientists had been thinking for a long time that African cichlids might have a good memory. But there was no clear evidence until the latest findings.

Just as a good memory can make our lives easier, it also plays an important part when a fish is trying to survive in the wild. "If fish are able to remember that a certain area contains(容纳) safe food, they will be able to go back to that area without putting their lives in danger," lead researcher Trevor Hamilton told Live Science.

So next time you are watching your pet fish from outside the tank, perhaps you should feel close to them-they may remember who you are.

1.We often feel sorry for fish because __________.

A.they have bad memories B.they can't remember anything

C.they are often used for research D.every moment in their lives is new

2.Why did the researchers carry out the research?

A.To know if fish can find food easily. B.To find out if fish have better memories.

C.To tell us fish can live for days without water. D.To show fish can live long without eating things.

3.What does the underlined word "tank" in Paragraph 2 mean?

A.A kind of fish food. B.A kind of hiding place.

C.A container for holding water. D.A container for keeping fish.

4.Which is true according to Trevor Hamilton?

A.Fish know where to get food. B.It's easy for fish to live in the wild.

C.A good memory can make fish safer in the wild. D.Fish are often in danger when they look for food.

5.Where does this article probably come from?

A.A story book. B.A science magazine. C.A news report. D.A travel book.

A wise man was walking from one town to another with a few of his followers, and they happened to pass a lake. So they stopped there to rest for a while, and the wise man said to one of his followers, “Could you please get me some water from the lake ?”

After they had rested for about half an hour. the wise man again asked the same follower to go back to the lake and get him some water to drink. And the follower went to the lake. This time he found that all the mud had settled (沉淀)to the bottom. the water was very clear and looked fit to drink. So he filled his water bottle and took it to the wise man.

The wise man took the water bottle and drank, then looked up at the follower. “ See what you did to make the water clean?” he said. “you let it be for a while and the mud settled down on its own, so that you could get some clear drinking water.
