【推荐1】Qomolangma is the third mountain of the Himalayas, so people call it the Third God Mountain in Tibetan language.

Qomolangma is very famous and it is higher than any other mountain in the world. Its newest height is 8,848.86 meters. At the height of 8,000 meters, there is only 30% O₂ and the human body can only stand this height for a few days, so it is dangerous for humans to climb higher. But many climbers want to challenge themselves. As Alan Arnette, a mountain climber from America, said “Climbing mountains drives you to look deep inside yourself, and lets you find out whether you are strong enough in mind when you want to stop.”

It’s a good thing that Qomolangma gives people a chance（机会）to become strong-willed（意志坚强的）when they are trying to achieve their dreams. However, Qomolangma is in danger these years because many people leave their waste behind, such as water bottles and plastic（塑料的）bags. They cause the environmental pollution for Qomolangma. Many animals would die after eating the plastic bags. Luckily, many volunteers from all over the world came to Qomolangma to join in the clean-up activity. A volunteer advised, “Mountain climbing lovers should always take good care of themselves, and at the same time, take good care of Qomolangma.”

White Pollution

People often call the plastic bags “white pollution”.    1     , it becomes the worst invention for the human. It is reported that it takes 100—200 years to break down the plastic bags completely. However, a 16-year-old high school Canadian student called Daniel Byrd discovered the way to break down the plastic bags!

    2    . He always helps her mother do the housework. Every time, when he opens the closet, the plastic bags fly out. This makes him very angry.    3    . With his teacher’s help, he found that when he put the two germs(细菌) mixture up and that made the plastic bags break down quickly.

He made an experiment first. He put some earth germs and plastic bags together. After 12 weeks, he found the plastic bags had been broken down.    4     The experiment also showed that the plastic bags could be broken down in three months. And they only gave out some water and little carbon dioxide ( CO2).

Now Byrd has got 30 thousand dollars from his invention.    5     . He has also got a lot of awards from many universities.

Scientists asked 361 college students to watch a sad movie. The 361 college students answered questions from the scientists before, after and three times during the movie to find out their different feelings, such as sadness (悲伤).

According to the result, scientists found out that people felt better after watching the sad movie. Scientists believed this was because the movie made them think about their lives.

“I want to live my life to the fullest, and this movie made me think a lot,” one student wrote.

Silvia, the head of the study, said that bad moods (情绪) would make people think more. “Good moods are usually a sign that everything is fine. You don’t have to worry, and you don’t have to think about your problems in your life,” she said, ‘‘But bad moods make you feel terrible. So, seeing a sad movie may make you feel bad, but that will make you think more about yourself and be full of hope in the future. ”

If it’s hard for you to communicate with your parents, don’t worry about it. Here is some advice for you to bridge the generation gap (代沟).

Don’t argue with your parents. Don’t get to your parents when you are angry. Your parents probably won’t consider your ideas if you are shouting at them. And you can’t express yourself well if you are angry. Go to some place to cool off. Make sure you understand why you are unhappy. Then think about what you want to say to your parents. If you don’t think you can speak to them at the moment, try writing a letter.

Try to reach a compromise. Perhaps you and your parents disagree on something. You can keep your own points and try your best to accept each other. Michael’s mother didn’t allow him to buy a motorbike. They talked and discussed about it. Finally they came to a compromise. His mother agreed that Michael bought the motorcycle, while Michael agreed to drive it only on certain days.

Of course, your parents might refuse to agree on something. In these situations, it is especially important to show love and respect to them. Showing respect will keep your relationship. If you show your love and respect to your parents, you will find it’s easier to communicate with them next time.

A good relationship with your parents can make you a better and happier person. It is worth having a try!
