3 . China has set new rules limiting the amount of time children can play online games. The rules limit children to just three hours of online game playing a week. That is one hour between 8 p. m. and 9 p. m. on Friday, Saturday and Sunday most weeks.

Li Zhanguo has two children aged 4 and 8. Even though they do not have smartphones, they enjoy playing online games. Like many other parents. Li is happy with new government rules. But experts say it is unclear if such policies can help prevent addiction to online games. Children might just get addicted to social media instead. In the end, experts say, parents should be the ones to set limits and support good practice.

There has been a growing concern in China about gaming addiction among children. Government reports in 2018 found that about one in ten Chinese children were addicted to the Internet. The new rules are part of an effort to prevent young people from spending too much time on unhealthy entertainment. That includes what officials call the “irrational fan culture”

Under the new rules, the responsibility for making sure children play only three hours a day as largely on Chinese gaming companies like Net Ease and Ten cent. Companies have set up real-name registration systems to prevent young users from going past game time limits. They have used facial recognition technology to check their identities. And they have also set up a program that permits people to report what is against the law. It is unclear what punishments gaming companies may face if they do not carry out the policies. And even if such policies are performed, it is also unclear whether they can prevent online addiction.

A specialist treating Internet addiction expects about 20 percent of children will find ways to break the rules by borrowing accounts of their older relatives and find a way around facial recognition. In his opinion, short-video alps such as Douyin and Kuaishou are also very popular in China. They are not under the same restrictions as games.

4 . Manta rays (魔鬼鱼) are some of the creatures in the ocean who allow divers to swim right up to and interact (与……互动) with them. Unfortunately, these gentle animals are in big trouble. Since 2011, manta rays have been listed as a threatened species worldwide.

Peru, a country in South America, recently took a big step to protect giant manta rays: It banned fishing for them. Although 12 other countries have passed laws to protect rays, Peru’s may be the most important one yet. That’s because there are more manta rays in the Pacific Ocean near Peru than in any other place in the world.

Giant manta rays are unusual-looking creatures. The giant, flat rays are typically about 4. 5 meters wide and can grow up to 8 meters wide! “They’re sort of like giant flying carpets underwater, ” says Joshua Stewart of the Manta Trust, an organization that researches manta rays.

People catch rays for their meat. Overfishing is bad for any sea creature, but it’s even worse for manta rays. Female manta rays usually have only one baby, every two to five years. So every ray that’s caught hurts the population in a big way. People who break Peru’s new law can be fined or have their fishing licenses taken away. Even rays caught accidentally in fishing nets must be set free.

Earlier this year, the Manta Trust attached video cameras, called Crittercams, to manta rays off the west coast of Mexico. The footage (连续镜头) the cameras collect could help researchers predict where rays swim and when. The scientists could use the information to warn fishing boats to avoid these areas, helping reduce the number of accidentally caught rays.

Stewart says it’s important to protect these unique creatures. “There’s really no other animal that compares in size that you can have interactions with in the wild.”

In my teens, I realized that I was ______ to my friends. They were all beautiful young ladies and I had these terrible scars under my clothes which made me feel ugly. ______, swimming helped me a lot. I can’t ______ that I was burned (烧伤) in the water and yet it also helped to ______ me. In the water I was at my happiest.

8 . It is difficult for parents of nearly every family to teach their children to be responsible (负责的) for housework, but with one of the following suggestions, you really can get your children to help at home.

If you give your children the impression (印象) that they can never do anything quite right, then they will regard themselves as unfit or unable persons. Unless children believe they can succeed, they will never become totally (完全地) independent.

My daughter Mary’s fifth­grade teacher made every child in her class feel special. When students received less than a perfect test score, she would point out what they had mastered (掌握) and declared (宣称) firmly they could learn what they had missed.

You can use the same technique when you evaluate (评价) your child’s work at home. Don’t always scold (责骂) them and you should give lots of praise instead. Talk about what he has done right, not about what he hasn’t done. If your child completes a difficult task, promise him a Sunday trip or a ball game with Dad.

Learning is a process of trying and failing and trying and succeeding. If you teach your children not to fear a mistake of failure, they will learn faster and achieve success at last.

9 . If you have a thought in mind that you can achieve the same goal within less amount of time and hard work by cheating to achieve success, then you shall feel bad later in future. You may have achieved a goal but you choose a wrong path. So, always remember that the path you choose in your life chooses your destination and then you shall not have an option to change it.

It is good to fail though it may take you to terrible feelings of life but in return, you will learn many things that life offers. The struggle is true but after that, the sweet of the fruit will build up your confidence to face any kinds of problem in the future. But if you prefer cheating, then you shall always live in fright.

Honour is like a coat, which you can wear confidently. If you cheat to achieve a goal, then you cannot hide it. Billy was lazy in hard work and used to delay all his work. He always thought of taking a fake degree to enter a big company. When the company CEO asked him to write a program for a certain topic, then he was quite shocked as he was unable to do the work, because he had no knowledge on the programming language and had faked his certificate.

Honour teaches you how to be disciplined. Being well-educated people, we should know what is good for us. It is always good to fail because at the end of the day, you will learn something new that will help you grow much stronger rather than cheating to achieve success, which will make you regret sooner or later.

All in all, success can be achieved via shortcuts but honour can never be. It’s better to live everyday with honour than to cheat.

10 . Nuclear bombs. That’s the go-to answer for incoming space objects like asteroids (小行星) and comets, as far as Hollywood is concerned. Movies like Deep Impact and Armageddon rely on nuclear weapons, delivered by stars like Bruce Willis, to save the world and deliver the drama.

But planetary defense experts say in reality, if astronomers spotted a dangerous incoming space rock, the safest and best answer might be something more subtle, like simply pushing it off course by crashing it with a small spacecraft.

That’s just what NASA did on Monday evening, when a spacecraft headed straight into an asteroid called Dimorphos, which is around 7 million miles away and poses no threat to Earth. It’s about 525 feet across and orbits another larger asteroid.

In images streamed as the impact neared, the egg-shaped asteroid grew in size from a little spot on screen to having its full rocky surface come quickly into focus before the signal went dead as the craft hit right on target.

Events happened exactly as engineers had planned, they said, with nothing going wrong. “As far as we can tell, our first planetary defense test was a success,” said Elena Adams, the mission systems engineer, who added that scientists looked on with “both terror and joy” as the spacecraft neared its final destination.

The impact was the peak of NASA’s Double Asteroid Redirection Test (DART), a 7- year and more than $ 300 million effort which launched a space vehicle in November of 2021 to perform humanity’s first ever test of planetary defense technology. It will be about two months, scientists said, before they will be able to determine if the impact was enough to drive the asteroid slightly off course, probably shortening its original orbit.

NASA plans to launch an asteroid-hunting space telescope named NEO Surveyor in 2026. “We’ve tracked lots of space rocks, especially the larger ones that could cause extinction-level events. Thankfully, none currently threatens Earth. But many asteroids the size of Dimorphos haven’t yet been discovered, and those could potentially take out a city if they came crashing down.” explains Lindley Johnson, NASA’s Planetary Defense Officer.
