1 . When you and your family go out for dinner, do you notice how many dishes you usually order? It’s OK if you finish all of them. But if you waste too much food, you need to pay for it.

Last year, China’s top legislature (立法机关) reviewed (审议) a draft law (法律草案) for stopping food waste for the first time. In general, a draft will become law after the top legislature reviews it three times.

According to the draft law, restaurants should tell customers not to order too much. If customers leave too much food uneaten, restaurants can charge (收费) them for food waste. The law also bans (禁止) waiters from encouraging people to order too much food. Some restaurants may use the “N-1” mode for people to order dishes. “N” stands for the number of persons at a table. So if there are six people at your table, you should order just five dishes, which can help people control the amount of dishes in a proper way.

The draft law also asks schools to teach their students to avoid food waste. It also bans TV programs about overeating and overdrinking. Producers of such programs will face a fine of up to 100,000 yuan.

Food waste happens in many places and has long been a big problem around the world. We need to obey the law and refuse to waste food.

4 . It might be fun to use your smartphone, but be careful. Too much screen time may be harmful to your health.

First, it is bad for your eyes. A researcher called Sarah Hinkley says the problem comes from the blue light that the screen gives out. Looking at a smartphone for a long time can cause eye strain（劳损）, headaches and dry eyes. So it is a good idea to take a break every 15 minutes when you are working at a computer or using a smartphone.

Second, screen use can do harm to children’s brains. A new study shows that using screens too much can affect（影响） how children’s brains grow. If children use screens for more than one hour a day, they might have lower levels of white matter in their brains. White matter is a key to the development of language and reading skills. So it is wise to cut down the time of children using all kinds of screens.

Third, using screens too much will affect your sleep. According to a study, about 95% of the people between the ages of 13 and 64 use electronics before bed, especially the young people under 20. Doctors say that the light from those electronics at night may make you excited before you go to bed. Then it’s hard for you to get enough sleep. So you’d better turn off smartphones, TVs, and all other screens an hour before your bedtime.

To keep healthy, doctors and researchers strongly advise that you shouldn’t use screens for long hours.

5 . Nowadays, many people are looking for fun online. Watching live-streaming (直播) shows has become part of their lives. At the same time, traditional culture has found a bigger stage online. Many traditional artists are starting to live-stream like Douyin and Bilibili. Some of them sing Peking Opera, some make paper cutting, while others perform Chinese classical music. A growing number of young people are starting to become more interested in traditional culture because of live-streaming.

Li Jun is a Peking Opera performer from the Shanghai Jingju Theater Company. The 59-year-old took up his smart phone and started to live-stream. Unlike performing on a real stage, Li uses common places as his stage, including his office and study room. Except singing, Li also teaches viewers about Peking Opera. People can ask him questions and get answers directly.

“Live-streaming has brought this traditional art down to earth.” One viewer said, “it gives young people an easier way to learn more about the traditional art,” Li has more than 70,000 fans on Douyin, while one of his videos got 42,000 views on Bilibili.

March third in the lunar calendar is China Huafu Day. On April 22nd this year, Bilibili live-streamed a huafu show on the fifth China Huafu Day. Performers showed clothes in traditional Chinese styles, including those from Wei, Tang and Ming dynasties. During the show, viewers not only enjoyed looking at the clothes, but also watched how performers used ancient styles of make-up.

As Guangming Daily said, live-streaming has come to a new stage through which traditional culture can be kept alive.

6 . If you want to be a better reader, what should you know about the speed of reading?

Some people read very quickly and others read very slowly. But which one is better?

The quick reader may be a good reader when he reads a storybook for fun. But he may not be able to slow down to read instructions (说明书) carefully. The slow reader may be a good reader. But he may spend too much time reading a story for fun. So the reader who reads everything quickly or the one who reads everything slowly isn’t really a good reader.

Knowing why you are reading or what you are reading can help you to know whether (是否) you need to read quickly or slowly. Some things should be read slowly. You must read these things slowly all the time to understand and remember everything important. Example (例子) are instructions for making or doing something. Also, math books, science and even some storybooks are full of important information. However, some things should be read quickly. Examples are picture-books for enjoyment, letters from friends, and some quick news from newspapers.

In some of your reading, you must change your speed from fast to slow and slow to fast. You will need to read some pages quickly and then slow down and do more carefully reading when you come to important ideas. So, knowing when to change your reading speed is one important symbol of being a good reader.

7 . ①Otters (水獭) are cute water animals. Recently, there has been a trend (趋势) of keeping them as pets. In Japan, some “otter cafes” are open for business. People can pay to play with the otters there and to take photos with them. In Indonesia, people go swimming with their pet otters and take “funny” videos. These photos and videos posted online have attracted more people to buy otters as pets.

②However, these photos and videos mask the fact that the online trade is doing harm to otters. In the wild, baby otters usually stay with their mothers during their first year of life. According to a report, 70 percent of otters sold online are under a year old. These baby otters have been stolen from their mothers. When they’re kept as pets by humans, they do not live full, natural lives.

③Otters are very social (群居的). They live in family groups of up to fifteen in the wild. Keeping an otter as a pet can make it very sad and lonely. These animals also need enough space to swim. Their owners’ bathtubs (浴缸) or pools are much smaller than the bodies of water in the wild.

④On the other hand, it is not wise to keep otters as pets at home. They have a very special fishy smell. If they’re kept indoors, they will leave a lot of droppings around the house. This would make the smell even more unpleasant. Besides, when otters are upset, they will make loud noises and even attack (攻击) people. If a person is bitten by an otter, he or she needs to go to the hospital immediately.

⑤So, what can we do to stop the otter pet trade? Well, one of the main ways is to let more people know that otters should not be kept as pets. We should also keep an eye on online posts about these animals. When photos and videos show baby otters being kept or sold as pets, don’t share them.
