We know that many animals do not stay in one place. Birds, fish and other animals move from one place to another at a certain time. They move for different reasons: most of them move to find food more easily, but others move to get away from places that are too crowded.

When cold weather comes, many birds move to warmer places to find food. Some fishes give birth in warm water and move to cold water to feed. The most famous migration (遷移) is probably the migration of fish, which is called “salmon”. This fish is born in fresh water but it travels many miles to salt water. There it spends its life. When it is old, it returns to its birthplace in fresh water. Then it gives birth and dies. In northern Europe, there is a kind of mouse. They leave their mountain homes when they become too crowded. They move down to the low land. Sometimes they move all the way to the seaside, and many of them are killed when they fall into the sea.

Recently (近來), scientists have studied the migration of a kind of lobster (龍蝦). Every year, when the season of the bad weather arrives, the lobsters get into a long line and start to walk across the floor of the ocean. Nobody knows why they do this, and nobody knows where they go. So, sometimes we know why humans and animals move from one place to another, but at other times we don’t. Maybe living things just like to travel.

You want to know about life in the past. Right? I can tell you. When I was a boy, things were different. I had to get up at six every morning. That was not very bad in summer, but in winter it was cold. And we didn’t have any hot water in the house. We had to wash in cold water. We didn’t have a bathroom（浴室）. My dad had some chickens. I had to feed（喂養(yǎng)）them every morning and then I had to walk to school with my little sister. It was about two miles （英里）to school and about two miles back in the evening. But it always seemed longer in the morning when we were going to school. There was a bus, but we didn’t have any money. And we had to goto bed at eleven o’clock every night because I had too much homework and housework to do. We couldn’t watch TV because there wasn’t any. On Sundays we had to go to church （教堂）three times － morning, afternoon and evening. And we couldn’t play outside on Sundays. But it wasn’t all bad. We had some g ood times（時光）. We could go out and our parents didn’t have to worry about us. There weren’t so many cars on the roads then, so the streets were safe to play in. And ther e were not many robbers and thieves in those days. We had to work hard and we weren’t able to buy all those things in the shops today. Life was hard, but it was simple and people were hap pier. I don’t think I’d like to be young today.

With the development of science, more and more students don’t like taking notes by hand. Instead, they use digital (數(shù)碼的) cameras to take pictures of the words that their teachers write on the blackboard or record what their teachers say in class.

The children might think there are too many notes to take or their teachers write or speak so fast that they can’t take more specific notes. They are trying to find ways to make things easier, so they use digital cameras. In fact, children are very clever to make use of technology (技術(shù)).

But do digital cameras really make taking notes easier?

Not really. Before you read notes from digital cameras, there are a lot of things you have to do. To begin with, you have to find a computer. Then you need to copy the photos into the computer. Next, you have to find a printer (打印機) to print the photos. Another thing is that you can’t hear the sound from the digital cameras clearly because there is usually lots of noise. You will have to listen to it slowly several times before you understand everything.

In fact, taking notes by hand has many advantages. For example, it can help you remember and understand what you are learning. In order to save time, you can choose the most important things or the things you don’t understand to write down. You don’t have to write down everything.

Don’t be afraid to take notes by hand. It’s really an effective (有效的) way.

1. Why do more and more students take notes with digital cameras but not by hand?

A. Because they want to take right notes.

B. Because their teachers want them to do so.

C. Because they want to make taking notes easier.

D. Because they always want to try new things.

2. How many steps do the students need to read the notes from digital cameras?

A. Four. B. Three. C. Two. D. One.

3.The underlined word “noise” means “_____” in Chinese.

A. 噪音 B. 音調(diào) C. 口音 D. 錄音

4.Which of the following is TRUE about taking notes?

A. You shouldn’t be afraid to write down everything.

B. To save time, you should memorize instead of taking notes.

C. You should write down all the words that your teachers write on the blackboard.

D. You only need to write down what you don’t understand or some key words.

5. What does the writer think is the best way to take notes?

A. By taking pictures of the words that teachers write.

B. By recording what teachers say in class.

C. By using a computer.

D. By taking notes with your hand.
