Recently, because more students use computers for a long time to have online lessons, more of them are feeling eyestrain(眼睛疲劳). A lot of eye doctors have studied this problem and have found ways to solve it. Following their advice will help keep computer users more comfortable.

★Lighting

The light in a room shouldn’t be brighter (明亮的) than that of the computer screen. Maybe in many students’ rooms, however, the light is far brighter than it should be.

★The screen

Many people think that having light letters on a dark background(背景) can cause less eyestrain, but they are wrong. In fact, it is best to have dark letters on a light background.

★Angle(角度) of looking at the computer screen

Students should sit a little higher than the computers so that they are looking down at the computer screens. The top of the monitor(显示器) should not be so high as the top of a student’s head.

★Breaks

If students spend a long time in front of a computer screen, it can cause eyestrain. Students should take a break by looking away from the screen every fifteen or twenty minutes. During that time they should either close their eyes or look at things far away.

1—2题完成句子;3题简略回答问题;4题找出并写下全文的主题句;5题将文中画线句子译成汉语。

【推荐3】Time is very important to us. When and by whom were the watches or clocks invented? Perhaps nobody knows. 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 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 day. If you don’t have a clock that shows time, you still know that when the sun shines, it’s day, and when it’s dark, it’s night. The sun can not only tell you whether it’s day or night but also it’s morning, noon, or afternoon. When the sun is almost directly overhead, it’s noon. People who live near the sea know time from the tides(潮汐). In the daytime, for about six hours, the water rises higher and higher on the beach. The same thing take place again at night. There are two high tides and two low tides every 24 hours. 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.
