【推荐1】Different people have different kinds of habits. Habits are the things people always do. For example, some people like sleeping (睡觉) late, some people like dancing (跳舞), some people like watching TV and some like reading books. These are all habits.

There are two kinds of habits: good habits and bad habits. Good habits are good for our lives. For example, reading for one hour each day is a good habit, because we can know a lot of things from it. Bad habits are bad for our lives (生活). For example, sleeping too late is bad for our health, so it is a bad habit. We should take more good habits and stop (停止) those bad ones.

【推荐2】With her eyes feeling increasingly tired and her vision blurry (模糊的), 16-year-old Sun Run went to the hospital with her parents in January. She was shocked when she found out that her eyesight dropped from 5.0 to 4.6 in only a term. “A few of my friends have had the same experience lately,” Sun said.

In fact, poor eyesight among Chinese primary and high school students rose from 59.2 percent to 70.6 percent in the first six months of 2020, according to the Ministry of Education.

To protect students’ eyesight, the Chinese government has worked out new requirements for school supplies and equipment. For example, according to the requirements, the size of text in students textbooks should be no smaller than nine-point (小五号).

Teachers should also avoid using projectors (投影仪) or other multimedia equipment (多媒体设备) that are too bright, Beijing Daily reported.

There are also requirements for desk and classroom lights. For example, these lights should give of as little blue light as possible.

Blue light is bad for our eyes, as it can kill the photoreceptor cells (感光细胞) we need for vision, according to Harvard Medical School. Many of the electronic devices (电子设备) we use every day, including our phones and computer screens, give off blue light.

Chinese government has also taken other steps to protect students’ eyesight in China. In May 2020, the National Health Commission requests schools to make sure that students have at least two hours of outdoor activities a day.

【推荐3】Three types of memory

Some scientists believe that there are three types of memory—immediate, short-term and long-term.

Immediate memory holds information for less than a second, e.g. the name of a road you have just seen. Then it either forgets it or passes it into short-term memory.

Short-term memory can hold about seven items of information at a time, e.g. telephone numbers. It holds them for about 30 seconds. Then it either forgets them or passes them into long term memory.

Long-term memory can hold information for the whole of our lives. Some scientists believe that there are two types of long-term memory. One type remembers events, e.g. the Beijing 2008 Olympic Games. The other remembers knowledge, e.g. the names of countries or the meanings of words.
