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.

【推荐2】Nowadays, e-hongbao is quite popular in China. People think that e-hongbao comes from lucky money for the Spring Festival. It’s a new convenient(方便的)way to send wishes. People hope to get good luck from it.
People send e-hongbao not only on festivals but also in other situations(情况). On birthdays, for example, people may get e-hongbao from family, relatives and friends, especially when they are not in the same place. For another example, February 14th is special to lovers. To express(表达)their love, Chinese lovers like sending each other e-hongbao of 5.20 yuan or 13.14 yuan.
People like playing e-hongbao games on smartphones. In the games, people all hope to get more money. Some of the lucky ones may get much while some get only a few fen. No matter(不管)how much money they get in the end, they want to try their luck. Usually, the person who gets the most money will send e-hongbao one more time. In fact, whether they get much or little, they have lots of fun.
You can also use the money from e-hongbao to pay. If you forget to take a wallet with you when shopping or eating in restaurants, don’t worry. A smartphone can help you out. That’s great, isn’t it?

【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.

Many people spend large part of time indoors—as much as 80-90% of their lives. We work, study, eat, drink and sleep in enclosed (封闭的) environment where there isn’t much fresh air. For these reasons, some experts feel that more people suffer from the effects of indoor air pollution than outdoor pollution.
There are many reasons to cause serious indoor air pollution, such as smoking, cooking and heating appliances (仪器). Also we can smell vapors (蒸汽) from building materials, paints, furniture, which can cause pollution inside buildings. Some kind of natural dangerous gas from the earth can be found concentrated (集中的) in basements (地下室) in some parts of the United States.
Pollution at home and work is often greater than outdoors. It is estimated (估计) that indoor air pollution levels are 25-62% greater than outside levels and can cause serious health problems.
Both indoor and outdoor pollution need to be controlled and prevented.
1. What is the passage about?2. Why do some experts say we suffer more inside?
3. Nature doesn’t produce dangerous gas, does it?
4. How many kinds of indoor pollution are mentioned in houses in this passage?

Since the outbreak(爆发) of the pandemic(疫情), it has made its way around the world. It has a strong influence on our daily life. People have found a way to protect themselves by wearing face masks(口罩). We must wear masks anywhere in public. But the masks are onetime items. This means that we need to discard(去弃) them after one or two uses. The world has seen wasted masks strewn(散布在) all over the streets and filling up garbage bins(垃圾箱).
Experts have pointed out that the materials used in masks are difficult to degrade(降解). It will take at least 100 years for them to degrade naturally. Environmentalists become quite worried because a countless number of wasted masks have ended up in the sea! They are polluting the sea! The sea animals suffer(遭受) a lot and so do we humans. If the sea animals eat them by mistake, the rubbish will be hard to digest(消化) and stay in their stomachs forever. The bacteria on the masks may kill them too. They will not only largely influence the ecological balance(生态平衡) of the sea, but also can spread some more dangerous illnesses. People will also leave these harmful things in their own bodies and may become ill when eating these sea animals.
In general, the harm of wasted masks to the sea is serious, so we must take action to stop it in a proper way right now. We should leave them in a safe place and find a wise way to recycle them.

Tea is an important part of Chinese tradition. Tea has a very close relationship to Chinese culture.
It is said that Chinese tea was discovered by King Shen Nong. People say that he lived 5000 years ago. One summer day, while he was visiting a faraway part of his country, he felt very thirsty. The servants began to make water hot enough to turn into gas for him to drink. Dried leaves from a near plant fell into the water. The king drank some, and found it could make him feel less tired. Also as a scientist, Shen Nong was interested in the new drink.
Drinking tea has many advantages. It makes people feel less tired and clears heat inside the human body. As you add a cup of tea to your daily life, please check the following helpful advice.
●Drink it hot. Tea oxidizes(氧化) quickly, so it is suggested that you drink it hot.
●The best time to drink tea is between meals. It may not make you have a strong wish to eat when your stomach is empty, or cause stomachache when your stomach is full.
●Do not drink with medicine. It may change the medical result. You can drink tea two hours after you take medicine.
●Green tea is the best choice for office workers. Why? Because green tea helps stop the bad result of the computer.
●Do not drink too much strong tea. If you make the tea too strong, it will probably be harmful to your stomach and make you feel sick.

It's aproblem that every year thousands of people get hurt or die when they are crossing the road. Most of these people are old people and children. Old people often get hurt or die because they can't see or hear well.
Children often get hurt or die because they are not careful. They forget to look and listen before they cross the road. How can we reduce(减少)traffic accidents?First,all of us must obey(遵守)the traffic rules. For the drivers,they shouldn't drive too fast. If they drive too fast,it will be very difficult to stop the cars in a very short time. The drivers mustn't drink wine(酒)before they drive out. For the walkers,first,they must be careful when they are walking on the road. When they walk across the road,they must try to walk underpases(地下通道)or footbridge(人行桥). If there are no underpasses or footbridge,we must walk the crosswalk(人行道). We must stop and,look both ways before crossing the road. Look left first,next look right,then look left again. Only when we are sure that the road is clear,we can cross it. The right way to cross the road is to walk quickly. It's not safe to run. If people run across the road,they may fall down. Second,try to help children,old people or blind people to cross the road. Third,never play in the street.

The World Health Organization says air pollution kills seven million people around the world each year. Even if polluted air does not kill us, it can make us very sick.
However, breathing dirty air may do more than hurt your body. It can also affect (影响) your brain and your ability to think.
A new study shows that air pollution can cause a “huge” reduction in our intelligence (智商). The researchers reported that long-term exposure (暴露) to air pollution can affect a person’s mental (智力的) abilities in two areas: language and math. Xi Chen, the researcher of the Yale School of Public Health led the study. He and his team found that breathing polluted air can reduce a person’s education level by about one year.
Chen said that the effect generally is worse for those over 64 years of age, for men and for those with little or no education. “The older persons—they are more affected. And we find, quite interestingly men are more affected than women. And people working outdoors are more affected than people working indoors.”
The researchers noted that the influence of pollution on language ability is even more serious as people age, especially among men and the less educated. Why are a person’s language skills more affected than math? There’s an important part in our brain: white matter. White matter is more connected with a person’s language skills. Studies have shown that air pollution has a great influence on the white matter in the brain.
Chen said that air pollution did affect the math skills just not as much as their language skills.
1. How many people are killed by air pollution each year?2. In what areas can air pollution affect a person’s mental abilities?
3. How are a person’s language skills affected by air pollution?
4. What do you think of air pollution? What’s your advice on stopping air pollution?
