What’s so great about exercise? Even though the thought of jogging, jumping rope, or getting hot and dirty makes you unhappy, there are ways that working out can still be fun. You might enjoy a game like volleyball, or maybe you ride your bicycle with friends. You could also get moving by walking your dog. These are all ways to work out, or exercise.

Exercise is a must in order to keep healthy. It makes your body stronger, gives you more energy, and even makes you feel happier.

When you exercise, you use your muscles(肌肉). This makes them stronger including muscles deep inside the body, such as your heart. The job of the heart muscle is to send blood(血液) throughout the body. A strong heart gets the job done much easier. It certainly is important to strengthen that muscle.

When you exercise, you feel like you have more energy. Energy is the power to move around. A healthy body does not have to work as hard to move, and it does not get tired as quickly.

Another advantage of exercise is that it makes you feel good. Exercise causes the body to produce a kind of chemical(化學(xué)物質(zhì)) in the brain(大腦) that calms you, and raises your spirits too. This chemical change makes you feel good, just like the good feelings you get from being stronger and having more energy.

Eating right is another way to stay healthy. Breakfast is very important if you make it a healthy one. It gives power to your body and to your brain. It’s easier to choose healthy foods if you know what you need. Children generally need about a cup and a half of fruit and a cup and a half of vegetables every day. You should drink between four and eight glasses of water and juice each day.

The final ingredient(因素) for good health is to get enough rest. Growing children need about nine hours of sleep every night. When the body is asleep, it repairs(修復(fù)) itself.

The body is like a machine. If you take good care of it, it can work well for a long time.

1.The word “strengthen” in Paragraph 3 probably means “________”.

A. to make something easier

B. to make something larger

C. to make something heavier

D. to make something stronger

2.How many advantages of exercise are talked about in the passage?

A. 2. B. 3. C. 4. D. 5.

3.What can we learn from the passage?

A. Sleep helps the body repair itself.

B. The body can work well all the time like a machine.

C. Healthy people don't feel tired when they exercise.

D. Children should drink eight glasses of water each day.

4.The passage is mainly about ________.

A. the importance of eating right

B. the importance of exercise

C. how to keep good health

D. how to feel happy

People use computers both at work and at home. They do maths, write, store (儲(chǔ)存) information, buy tickets, listen to music or play games. What do you know about the history of computers?

The first computers were very big. They were the size of a room! They were so big that people didn’t have them at home. Early computers could also only do easy maths. In the 1930s Alan Turning had the idea for a computer you could program to do different things.

In 1958 Jack Kilby first made the microchip (微型芯片). Microchips were very small but could store lots of information. They helped make computers smaller. In the 1970s computers were smaller and cheaper so people started to use them at home. In the 1980s computer games were very popular. Lots of people had computers just to play games.

In 1989 Tim Berners-Lee came up with the idea of the World Wide Web. Now people all over the world can look for and share information on websites.

Today people can use smartphones as well as computers to go on the Internet. In the past a computer was the size of a room. Now you can hold a smartphone in your hand.
