How do you study for exams (¿¼ÊÔ)? Different students have different ways. Some of my friends are sharing their ideas.

Angela: I often study very hard before exams. I don¡¯t play sports or games in the exam week. And I don¡¯t go out often. I study for hours at night. I don¡¯t go to sleep before 12 o¡¯clock, so I always don¡¯t have enough sleep. But it seems I need to change, because I usually want to sleep when I have exams. Of course I fail some of them. I feel bad!

Haitao: Before exams, I study very hard, too. I buy lots of books and do the exercises in them. Sometimes when I really get tired, I tell myself that I must do them. I think if I practise more, I can do better. But sometimes I feel more confused (À§»óµÄ) after doing the exercises. I can¡¯t remember the answers. I don¡¯t know why.

Andy: I never study late. And I don¡¯t do many exercises. I always read my notebooks carefully the day before the exam. And I have enough food and sleep. I don¡¯t think scores are important. I just try my best. Do I get good grades? Yes, I usually do.

How could we tell time if there were no watches or clocks anywhere in the world? The sun was probably the world¡¯s first ¡°clock¡±, except in the far north, where the Eskimos(°®Ë¹»ùĦÈË) live. There, it¡¯s dark most of the winter, and light most of the summer. But in most of the world, people have used the sun for a clock. Even today, if you don¡¯t have a clock, you still know that when the sun shines, it¡¯s day, and when it¡¯s dark, it¡¯s night. The sun can also tell you if it¡¯s morning, noon, or afternoon.

People who live near the sea can tell time from the tides. In the daytime, for about six hours, the water rises higher and higher on the beach. And then it goes down and down for about six hours. The same thing happens again at night. There are two high tides and two low tides every 24 hours.

Seamen on a ship learn how to tell time by looking at the moon and the stars. The whole sky is their clock.

In some places in the world the wind comes up at about the same time every day or changes direction or stops blowing. In these places the wind can be the clock.

A sand clock is an even better clock. If you had fine dry sand in a glass

shaped like the one in the picture, you would have what is called an hourglass.

The sand in the hourglass goes from the top part to the bottom part in exactly

one hour. When the hourglass is turned over, the sand will take another hour

to go back again.

In January this year, people found a bottle on a beach in West Australia. There was a message in the bottle. A German sailor threw the bottle into the sea in June 1886. That was 132 years ago! It is the world¡¯s oldest-known message in a bottle.

At the time, German sailors used messages in bottles to study how the salt water moves. Between 1864 and 1933, they threw thousands of bottles into the sea.

Writing messages in bottles is popular around the world. Some messages are used for scientific studies. But most people send out messages in bottles for other reasons.

Some want to find pen pals. So they write down some things about themselves. Some people write down their secrets. They hope the sea can take them away. There are even online messages in bottles. People can send them through WeChat or QQ.

The reasons and ways may change, but the idea behind the messages is always the same: People want to connect with others. This idea has made sending messages in bottles popular for hundreds of years.
