Do you want to keep away from colds? You must say, "Of course". Now, first, please put on a happy face.

A new study shows that happy and relaxing people seem to fall ill less often than those unhappy people. "It's possible that being happy helps the body fight illnesses," said the researcher Sheldon Cohen from New York University(大學(xué)). In an earlier study, Cohen found that cheerful and lively people caught coughs and colds less often. People's feelings seemed to affect their health. In this study, Cohen interviewed(采訪) 193 adults(成人) every day for two weeks. During the interviews, the people told researchers that the doctors asked them to stay alone in a room for six days because of the cold.

The results showed the people who said they felt happy during the research period, their illness were less serious and lasted for a shorter time. Cohen believes that when people have good feelings, their body may make a chemical, and it can help fight illnesses and diseases.

So if you are worried about your health, look on the bright side more often. Just as the old saying goes, "A coin has two sides".

1.What does the underlined word "researcher" mean in Chinese?

Have you ever rubbed your hands together when they get cold? Why do we do that? We do that for friction. Friction happens when two things that aren't very smooth rub together to make heat energy. The faster you rub two things together, the more friction (and heat) you can make. Let's discover friction!

WHAT YOU'LL NEED:

● Soap ● Water ● Your hands!

WHAT TO DO:

①M(fèi)ake sure your hands are dirty.

②Rub your hands together until you feel the heat of your hands.

③Now, use soap and water to get your hands very slippery(滑的).

④Try to make friction happen while your hands are slippery.

⑤Please write down what has happened.

LET'S TALK!

Friction is an energy that happens when two things tub together. When friction happens, it makes heat! When your hands are slippery, they won't make very much friction and your hands won't get so hot.

DID YOU KNOW?

● Friction happens when you stop your fast running bike.

● Ancient people made fires by rubbing two pieces of wood together. Friction happened though they didn't know it.

Friction is everywhere. Have you ever noticed situations where friction is happening? If not, ask your parents to take you out in a car. If it is not hot, touch the tires(輪胎) of the car before and after a short drive to see how much warmer they get from friction.

A robot is a machine. But it is not just any machine. It is a special kind of machine. It is a machine that moves. It follows instructions. The instructions come from a computer. Because it is a machine, it does not make mistakes. And it does not get tired. And it never complains. Unless you tell it to!

Robots are all around us. Some robots are used to make things. For example, robots can help make cars. Some robots are used to explore dangerous places. For example, robots can help explore volcanoes. Some robots are used to clean things. These robots can help vacuum your house. Some robots can even recognize words. They can be used to help answer telephone calls.

Some robots look like humans. But most robots do not. Most robots just look like machines. Long ago, people imagined robots. Over 2,000 years ago, a famous poet imagined robots. The poet's name was Homer. His robots were made of gold. They cleaned things and they made things. But they were not real. They were imaginary. Nobody was able to make a real robot. The first real robot was made in 1961. It was called Unimate. It was used to help make cars. It looked like a giant arm.

In the future, we will have even more robots. They will do things that we can't do. Or they will do things that we don't want to do. Or they will do things that are too dangerous for us. Robots will help us fight fires. They will help us fight wars. They will help us fight sickness. They will help us discover things.

They will help make life better.

閱讀與表達(dá)(問答式)

On 19th September 1783, Pilatre De Rozier, a scientist, sent the first hot air balloon. The passengers were three animals and the balloon stayed in the air for about 15 minutes before hitting back to the ground.

The first manned(載人的) flight was about 2 months later, with a balloon made by 2 French brothers. The balloon flew for a period of 20 minutes.

Sailing through the sky in the balloon, high above buildings and trees, you can't feel or hear the wind because you're traveling in the same direction and at the same speed as it is.

A hot air balloon has three main parts: the balloon, called an envelope; a basket, where passengers ride; and a burner system, which supplies the hot air.

Most balloon envelopes are made of strong, lightweight nylon(尼龍). They are different in size and shape, but they have to be really, really big to lift even one person. Most weigh more than an adult man.

The basket is usually made of wicker(柳條), which is strong but not too hard. It needs to bend a bit for a soft landing, just like a good jumper bends her legs instead of keeping them straight when she lands.

The hot air balloon works on the theory that hot air rises faster than cooler air. When the burner system is turned on, it makes a noisy sound, but once the balloon is flying, the burner can be turned off. The air in the envelope will then cool, and the balloon will slowly go down unless the pilot starts the burner system again.

To control a hot air balloon, a pilot adds hot air to it to go up or lets the air out to go down until he finds a wind blowing in the direction he wants to fly. But no matter which way the wind blows, the passengers have an amazing bird's-eye view of the world.

根據(jù)短文內(nèi)容，完成下列小題。

1.Who were the passengers on the first hot air balloon?

2.Did the first manned balloon fly for 20 minutes?

3.Why is the basket usually made of wicker?

4.How does a pilot control the hot air balloon?

5.What are the main points in this passage?
