There are many ways to help improve your health like eating healthy food, taking exercise and getting medical help. But the easiest and cheapest way to improve your health is just to sleep eight hours or more every night. The general sleeping rule is that the younger you are, the longer sleep you need. But regardless of(不管) age, some people need to sleep more while for some a few hours is enough.

The problem with sleep is that more and more people in the world are not sleeping enough. According to the World Health Organization, over half the people in the world may be sleep­deprived. Having less sleep not only makes people feel tired but also causes accidents. In the United States alone, sleepy drivers cause at least 100，000 traffic accidents a year. Also sleep problems can cause medical problems such as high blood pressure(血压).

Why are so many people sleep­deprived? Part of the reasons may be cultural. In the American culture, people put a higher value on work than on sleep. In fact, people who sleep a lot are usually seen as “lazy”. Also, you can sometimes hear some people say proudly that they don't have much time to sleep, they only sleep four or five hours a night. It seems that the less you sleep, the more work you'll do.

How do we teach these people to learn the value of sleep? Perhaps they may listen to the advice of Dr.James Maas, an expert(专家) in sleep. He says, “Sleep is like a credit(信用) card. When you sleep less, you are only borrowing time. You always have to pay it back. The more hours you don't sleep, the more hours you should sleep to ‘pay back’ the hours on your ‘sleep credit card’.”

For those who value work more than sleep, they should listen to what a famous person once said, “Don't think you will be doing less work because you sleep during the night. That is a foolish(愚蠢的) idea which is held by people who have no imagination. You will be able to do more.”

Experts in nutrition suggest that we should eat at least five different kinds of vegetables and fruit a day. They are very necessary for our health and help our bodies work well. They can help reduce the risk of getting ill. There are a lot of vegetables and fruit to choose from and they taste delicious. 1.

It's easy to buy our food from the local supermarket, so why do we go to the trouble of growing our own? Here are several good reasons：

2. You can pick and eat it at once. When you have tried it, you will agree that vegetables and fruit that are eaten straight from the garden taste better than anything you can buy in a supermarket.

You may want to cut down on your “food miles”—the distance that a product has travelled before it reaches your kitchen. Many food packages are flown halfway across the earth. 3. Homegrown food is likely to be healthier. Food producers often use fertilizers and pesticides which can end up in your food. If you grow your own, things are different. 4. You might also choose to grow some traditional vegetables and fruit. These often have more important things that keep you healthy.

5. And you can grow your own even if you only have a small backyard. Some food can grow well in pots, including tomatoes, potatoes and carrots. You can recycle plastic bottles and cups to grow something. Just make sure there are holes for drainage and a small plate under them to catch drops of water.

A.Best of all, you can grow your own!

B.That's not so good for you, or for the planet.

C.Food that you grow yourself is always fresh.

D.If you have a large garden, growing your own is easy.

E.You can control what goes on and into the food you eat.

Most people hope to have a memory which helps them succeed in study, work and life. Can memory be improved? Luckily, hundreds of studies in the past 50 years have already given us a clear answer.

A healthy lifestyle keeps your brain young and memory sharp. First of all, it is necessary to have a healthy diet. Eating more food rich in B vitamins and Vitamin E, such as vegetables and lean meat, helps you have a better memory. Second, doing exercise can keep your brain alive, too. Proper exercise provides much needed oxygen for the brain. Running, riding a bike, swimming and even walking two or three times a week are helpful. Third, getting enough sleep is important. Only when your brain gets a good rest, can it work well. The healthier your lifestyle is, the better your memory will become, but do not expect a sudden change—it takes a long time to make a difference.

Memory skills help you remember things better. The following three are the most widely used. Chunking is a way of remembering a piece of information by cutting it into smaller ones. For example, to memorize a ten—digit telephone number 2127983630, you can divide the digits into three groups: first 212, then 798, and lastly 3630.This method is much more effective. Organization means organizing information into groups of the same kind. For example, trees, grass and flowers are plants; tigers, pandas, horses and cows are animals. Imagery is remembering newly learnt information by using your imagination and connecting it with something that you are familiar with.

However, memory skills will hardly work if you don't understand the information. What's more, only a regular (有规律的) review can make the memory last long. That is why students are always advised to go over what they have learnt after one day and then after three days, and then use it as regularly as possible.

Human brains are like muscles that need nutrients and exercise to become stronger. If you make a few lifestyle changes and try some memory skills, you can certainly improve your memory.

Many people say dolphins are intelligent. They seem to be able to think, understand and learn things quickly. But are they as smart as humans, or are they more like cats and dogs? Dolphins use their brains quite differently from the way humans do. But scientists say dolphins and humans are very similar in some ways. How?

Like humans, every dolphin has its own “name”. The name is a special whistle(哨声). Each dolphin chooses a specific(特有的) whistle for itself, usually by its first birthday. Dolphins are like people in other ways, too. They “talk” to each other about a lot of things—such as their age, their feelings, and finding food. They also use a system of sounds and body language to communicate. Understanding dolphin conversation is not easy for humans. No one “speaks dolphin” yet, but some scientists are trying to learn.

Dolphins are also social animals. They live in groups called pods, and they often join others from different pods to play games and have fun—just like people. Scientists believe playing together is something only intelligent animals do.

Dolphins and humans are similar in another way: both species make plans for getting things they want. In the seas of southern Brazil, for example, dolphins use an intelligent plan to get food. When there are fish near a boat, dolphins signal(发信号) to the fishermen to put their nets in the water. Using this method, the men can catch a lot of fish. Why do dolphins help the men? There is an advantage for them: they get to eat some of the fish that escape(逃脱) from the net.

1.What is a dolphin's “name”？

A.It is a kind of game.

B.It is a body sign.

C.It is a dolphin's age.

D.It is a specific sound.

2.Scientists believe ________ is something only intelligent animals do.

A.singing songs B.playing together C.finding food D.making decisions

3.What can we infer from the passage?

A.Some scientists can understand dolphins' system of sounds.

B.Dolphins probably help fishermen by using their body language.

C.Humans join dolphins' groups to get things we want.

D.Dolphins can talk to humans about their age and their feelings.

4.What's the main idea of the passage?

A.Dolphins can communicate with each other at birth.

B.Dolphins are social animals because they play together.

C.Dolphins are smart and are like humans in some ways.

D.Dolphins help humans do many things like catching fish.
