Would you completely trust your friends if you couldn’t see anything? If you are falling, do you believe they will catch you and help you stand up? Our teacher helped us to find the answer.

Our teacher is named Morrie. One day, he said that he had a game for us to try. He divided us into two groups. One of the students from the first group, stands in front of us with his eyes closed, and then falls backwards(向后). The second group stand behind him. Before he falls on the floor, they should catch him and not let him get hurt. Most of us were uncomfortable with this. We were afraid that they wouldn’t catch us and we would hit the floor. So we didn’t move. We just stood there and laughed in embarrassment(尴尬).

Finally, one student, thin, quiet, dark-haired girl called Sarah, decided to move. She crossed her arms in front of her body, closed her eyes, and slowly fell backwards. She looked quiet but brave.

For a moment, I was sure she was going to fall on the floor. But before she hit the floor, the other students caught her, held her and finally helped her stand up.

“Whoa!!” we were all surprised, and also encouraged. The girl was happy, too. Seeing this, Morrie smiled and said to the girl, “When you close your eyes, you can’t see anything. You won’t feel safe. When you are falling, the feeling gets stronger. You are not sure whether you will hit the cold, hard floor or the warm, soft hands of your friends. But if you are brave enough to trust them, they won’t let you down.”

“How many common English words were invented by Shakespeare?”

How long did it take people to find the answer to this question 15 years ago? And now! you can google it and find the answer immediately!

Google is the most popular Internet search engine in the world. It was invented by two students, Larry Page and Sergey Brin. They met in 1993, when they were studying computer science at Stanford University, USA. They dreamed of producing something that could also answer any question in seconds.

Internet search engines at that time were slow and gave many websites that weren't useful. In January 1996, Page and Brin decided to make a better and faster search engine. They thought the results should be based on the most popular websites.

Nobody would give them money for their project, so they used their own money. They also borrowed money from family and friends. Then, in 1998, they were given a cheque for $100,000, and they started their own company. Their first office was in a friend's garage. The company's name is Google, a word which comes from mathematics. A “google” is a very high number----

1 followed by a hundred zeros.

The google search engine was soon used by thousands of people worldwide because it was fast, easy and correct. By 2002 it was the biggest search engine on the Internet. Now, more questions have been answered by Google than any other Internet service, from sport to science, and from music to medicine. Google hopes that in the future all the world's information will be put on the Internet, so that everybody can find everything.

Since January 2013, many cities in China have seen a lot of foggy days. In Beijing, only five days in January were free of smog (雾霾). What’s the difference between fog and smog?

According to scientists, fog is made up of tiny (微小的) drops of water and also ice particles (颗粒) during very cold conditions. Smog is dirty air that looks like a mixture of smoke and fog, caused mainly by smoke from cars and factories in cities.

An official for the Ministry of Environmental Protection told Beijing News that PM2.5 pollution is the main problem with air pollution. PM 2.5 refers to pollution with small particles 2.5 micrometers or less in diameter (直径).

According to the Chinese Academy of Sciences, two main factors that cause PM 2.5 are motor vehicles and the burning of coal.

Poor air has done harm to people’s health. Children and the elderly are more at risk. A report from Beijing Children’s Hospital shows that from January 5 to January 11, 2013, half of the patients in the hospital came for respiratory (呼吸道的) problems.

To respond to the air problem, the Chinese government and many Chinese people have started to take action.

Beijing announced a plan to use clean fuel in government vehicles and plant trees. It asked citizens to set off fewer fireworks for the Spring Festival celebration. They suggested that cars with large emissions (排放) should be banned and factories should be closely watched.

Three students from No. 4 High School in Beijing wrote a report to advise to fight the air pollution. “We hope more people will join us to protect our environment. With all our efforts, the blue skies will certainly return soon,” said Shi Yucong, 15, one of the three students.
