The government in China ended his one-child policy and let families have two children instead in 2015.

    A Chinese Communist Party statement gave a number of reasons for the change in policy. The statement said the change is meant to balance population development, stop a falling birth rate(出生率)and strengthen the country's labor force(劳动力). China, with the largest population in the world, started the one-child policy in 1980. But the government allowed only a small number of couples to have two children. For example, some families in the countryside could have two children, if the first-born is a girl.

    In 2013, the Chinese government gave other couples a chance to have two children if one of them was an only child.

Jiang Quanbao, a teacher and population expert, explained how Chinese families react(反应) to the newest policy. "Too many young people in the cities are no longer interested in having a second child," he said. "People in the countryside are more interested. But some of them are already allowed to have two children." At the end of 2014, China had a population of 1.37 billion people. A total of 800 million of them have jobs. But the labor market need of labor by the year 2050. With the two-child policy, an increase in births can solve this problem.

    Boys and girls, what do you think of the two-child policy? Do you want to have a new-born brother or sister?

Do you like a small plant? The study shows that a small plant can improve our memory (记忆力) and make us happier. Even the small plants on your desk may have a more effect on you than you might realize. The small plants can help you to think more clearly. Studies have shown that the small plants could improve your concentration (注意力) by up to 20% and improve your ability to remember information by 15-20%. Plants can also reduce CO₂ and improve air quality.

"CO₂ should not pass 1,000 parts per million in the classroom." Doctor Zhang in the Health and Safety Center said. He said this level can cause headache and even lead to poorer decision-making. Studies have shown that sometimes indoors plants can reduce CO₂ from 2,000ppm to about 480ppm in less than one hour. Plants can increase happiness because there is endorphins (内啡肽) in humans. The shape, color, smell, feel and taste of plants can cheer us up and improve our memories.

A new high-speed railway opened on January 22nd, 2021. The new line which connects Beijing with China's north-eastern provinces not only shortens travel time. but also has high technologies, Besides, it also has an environmentally-friendly design. Importantly, it shows China's strong ability to build the high-tech and green high-speed railway, 

The new line connects Beijing with Shenyang, Changchun and Harbin- the capital cities of China's three north-eastern provinces.▲But now the newline shortens the travel time between Beijing and Harbin to less than 5 hours. People have never stopped realizing the goal of a higher speed. 

A part of the way from Harbin to Shenyang was put into work in 2012. The newline has 46 bridges and 30 tunnels（隧道）, " The building of the station is based on the idea of environmental protection, " the station's designer Wang Qingyi said. Also, an electricity-saving system has been used to save energy, Because of the new design lights will not need to be turned on during the day. Because the hall is bright enough for passengers. 

A new type of train that can work under temperatures as low as -40℃ runs on the line. The new train can stand the coldest weather and provide Braille (盲文). It has become attractive in the world. Many foreigners come to China to experience the new type train. Chinese people use their wisdom and hard work to tell the world that they are going to have a bright future.

I have changed a lot in the last few years.

 It's said that about 4% of people sleepwalk(梦游) at night during their lives. That is, you or some of your families and friends have done so. Sleepwalking happens while one is sleeping. Sleepwalkers walk slowly around the house, say something and then go back to sleep. Their eyes are usually open and look right at you as if they were awake. The next day, they remember nothing when they are asked about what happened the night before.

 Sleepwalking is a common problem for many children from 4 to 12 years old. It could run in family. If one of the parents is a sleepwalker, their children may be, too. Scientists still don't know why people sleepwalk, but they find common facts that may lead to sleepwalking. For example, if one is under stress, gets sick or doesn't have enough sleep, he or she will have more chances to sleepwalk. Sleepwalking itself isn't bad, but it may make sleepwalkers get hurt because they are in fact"sleeping" and don't know what they are doing. It is important to keep sleepwalkers from falling down, running into something and even walking out to drive.

 What can we do for sleepwalkers? First, try not to wake up a sleepwalker because it may make him or her scared. All you have to do is to show the sleepwalker the way back to bed. Second, close the windows and doors to stop sleepwalkers from going out. Third, keep any things that may hurt the sleepwalkers away. Remember, if you find someone sleepwalking, the most important thing is to make sure he or she is safe.
