What will the weather be like in the future? Some people say they can forecast the weather from some animals.

If birds are flying high in the sky, there will be a nice day. When they sit in trees or stay close together, bad weather is on the way. Ants(蚂蚁) often build their homes on the steep(陡峭的) side just before the rain comes. Cats like to clean their ears before the rain. Chickens make a loud noise and run here and there when the rain is coming. Frogs will stay in the water and make a lot of noise, too. But on a nice day, they are quiet and jump out of the water. Turtles(海龟) often look for higher places and cows like to lie down when the rain is on the way。

We each have a memory(记忆力). That’s why we can still remember things after a long time. Some people have very good memories and they can easily learn many things by heart(心), but some people can only remember things when they say or do them again and again. Many of the great men of the world have got surprising memories.

A good memory is a great help in learning a language（语言）. Everybody learns his mother language when he is a small child. He hears the sounds, remembers them and then he learns to speak. Some children are living with their parents in foreign（外国的）countries. They can learn two languages as easily as one because they hear, remember and speak two languages every day. In school it is not so easy to learn a foreign language because the pupils（学生）have so little time for it, and they are busy with other subjects, too.

But your memory will become better and better when you do more and more exercises.

 We can express thoughts and feelings and send sounds and pictures on our smartphones today. We canˈt send tastes, smells or touches.But some scientists in Britain are trying to develop a way for smartphones to do that.

 To give users a sense of taste, Adrian David Cheok and some other scientists designed two electrodes (电极 ）. "You put these two silver electrodes in your mouth, and you put your tongue in between and then your tongue will get a virtual taste perception(虚拟的味觉） in your brain，"said ProfessorCheok .They have already created sour, salty, sweet and bitter tastes.

A device(设备）called "Scentee" allows users to have the sense of smell. Scientists put"Scentee "into a smart phone and can spray (喷射）small clouds of fragrance， including flowers, fruits and coffee. Professor Cheok says the person speaking can activate（激活） the device.ˈˈScentee ˈˈholds a container（容器）with about 100 different smells. The container must be replaced when all the smells run out.

 The sense of touch comes from a ring-like device. It is connected wirelessly （无线地） to the smartphone. “I can be in London and my friend can be in Tokyo, and I can squeeze （挤压）my finger and then theyˈll get a squeeze on their finger through the Internet. It’s a way of touch communication with small mobile devices,”Professor Cheok said.

  Professor Cheok hopes devices like these will someday be added to houses. He says they may change the future of long-distance communication.

There have always been a lot of commonly believed but false (虚假的) ideas about being fat and doing exercise. Some people believe that they can’t help putting an weight as they get older, while others hold that if they stop exercising, their muscles (肌肉) will turn into fat. Here are some more myths (神话).

I’ll never lose weight--I come from a fat family

Wrong! While we canˈt change the body type we are born with, we can’t blame our genes (基因) for making us fat. There’s plenty of evidence that fatness runs in families, and the main reason is that they share the same habit of eating too much and exercise too little.

I am fat because I burn calories slowly

Wrong! Fatness is not caused by a slow metabolism (新陈代谢). In fact, although fat people consume (消耗) more energy than slim people, they also fail to realize how much they eat. Keeping a diary can help you work out your daily food intake more accurately (精确地).

Exercise is boring

Wrong! Anything will become boring if you do it again and again. The key is to develop a balanced and varied (各种的) program that’s fun as well as progressive (不断进步的). If you enjoy a Sunday walk, take a different mute. If you do yoga (瑜伽), try a tai chi class.

No pain, no gain

Wrong! Exercise is not meant to hurt. Indeed, pain is your body telling you something’s wrong, and continuing to exercise could lead to serious injury (伤害). You may experience mild discomfort as you begin to exercise regularly, but this is your body adapting to the positive changes in your lifestyle and the aches should disappear quickly. If they donˈt, rest and ask for medical advice.

The giant panda

Population    in the wild: about 1,600

Appearance   Weigh at birth: about 100—200 grams

             Adult weight: about 100—150 kilograms

             Colour: black and white

   A giant panda is a kind of bear. It has a white face with black patches around its eyes. It also has black ears, shoulders and legs. The rest of its body is white.

   Pandas live high up in the mountains of Central and Western China. They live in the bamboo. In zoos, their menu includes bamboo, apples and carrots. A giant panda can eat as much as 30 kilograms of bamboo a day.

   Pandas like to live on their own. They need to eat a lot stay healthy, so they spend more than 12 hours a day eating. Although they are big and heavy, it is not difficult for them to climb trees. They are strong enough to protect themselves.

   Pandas live for about 20 years in the wild, but in zoos they can live for up to 35 years.

   People are cutting down forests, so the pandas are losing their homes. Some people are killing them for their fur. It is cruel of them to do so. There are not many pandas in the world now. It is important for us to protect them.

①Pandas are killed by some cruel people.

②pandas can’t protect themselves

③Some people damage the forests.

④pandas only live for about 20 years

We often say that lions and tigers are kings of animals. They’re the best hunters (猎手) and they’re at the top (顶端) of the food chain (链) on land. But the best hunters in the sea are sharks(鲨鱼). Sharks are bigger and swim   (1)   fasterthan other sea animals. They have wide mouths and sharp (锋利的)   (2)  . They are at the top of the sea food chain.

What’s at the top of the world’s food chain? Human beings (人类)! We’re not strong, but we’re the   (3)  . We can’t run fast, but we   (4)   cars; We can’t fight better, but we invented guns (枪),… Many inventions are useful to us.   (5)  , they’re also harmful. People ask the   (6)   for too much. For example, we ask for food, wood, fur and so on. As a result, forests are becoming    (7)  . Rivers are dirty and some animals are in danger of dying out.

Don’t forget that we’re part of the food chain. We should leave enough   (7)   for animals to live in. We should do something to stop people from   (8)   animals. We must know that protecting animals is just to protect   (9)  .

Early to bed, early to rise, makes a man healthy, wealthy and wise.

This is an old English saying. Do you know it before? It says that we must go to bed early and get up early in the morning. Then we should be healthy. We should also be rich (wealthy) and clever (wise).

      This is true. The body must have enough sleep to be healthy. Children of a young age should have ten hours’ sleep every night. Children who don’t have enough sleep can’t do their work very well. They will not be wise and they may not become wealthy!

      The body also needs exercise. Walking, running, jumping, swimming and playing games are all exercise. Exercise keeps the body strong.

      Exercise also keeps the blood（血液）moving around inside the body. This is very important. Our blood takes food to all parts of our body. The head also needs blood. Exercise helps us to think better!
