Once there was a king who told some of his people to dig a pond (池子).The king then told his people that one person   15  each family had to bring a glass of milk during the night and put it into the pond. So, by the morning, the pond should be   16 of milk.
After   17  the order, everyone went home. As one man prepared his milk, he thought that since everyone was bringing milk, he would just   18  a glass of water and put that into the pond instead.   19  it was dark at night, no one would notice it, so he quickly went and put the water into the pond and  20  home.
In the morning, the king went to visit the pond. To his surprise, the pond was only filled with water! What happened? Yes! Everyone had the same idea   21  that man. They all thought, “I don’t have to waste my milk. Someone else will do it.”
Dear friends, when you plan to help poor people or people in trouble, do not think that   22  will take care of it.  23 , it starts with you. If you don’t do it, no one else will, so change yourself and make a   24  .

One of my favourite things to do is hiking in mountains. Because nobody likes the idea of getting lost, I always prepare before every trip. But what’s the best navigation tool, a Global Positioning System (GPS) or a good old map and compass? Five of my friends and I hiked through the mountains on a trail I marked. One team of three carried a GPS, and the other team used a map and compass.

It took the GPS team 3 hours and 11 minutes to get through the whole hike, however, it took the map and compass team only 2 hours and 49 minutes. The biggest problem the GPS team met was that they lost the satellite signal (卫星信号) in some places. With no map or compass, they had to walk around until they were in a place where the signal was good. The map and compass team was able to spot (认出) different landmarks, compare them to their maps and then use the compass to point them in the right direction.

When I head out on my future hikes, I’m bringing a map, a compass and a GPS to show me the way.

It's the end of class. When the bell rings, students of Luohu Foreign Languages School in Shenzhen quickly take out their cell phones. They want to log on* to their micro blogs to check the interesting things that have happened in the last hour.
　　Since last year, the trend* of micro blogging has swept the country. Recent surveys shows that most students in middle schools have a micro blog and some even update* their blogs over five times per day.
　　"We learn many fresh and interesting things on micro blogs and they have become popular topics in class," said Andy Liang, 14. "If you do not know about them, you are out of the loop."
　　It is also a great place for students to let out stress. "My parents always ask me to study all the time, and encourage me before exams, but it really adds pressure," said Simon Zhang, 15. "When I share these feelings on my micro blog, I get many replies from friends in the same situation, which makes me feel better."
　　But parents are worried that micro blogging could be a waste of time. Some misleading messages may even cause danger to kids, they said.
　　Mr. Shen, a professor at the China Education Association, suggests parents not worry too much as long as kids are not crazy about micro blogging. Maybe it can become a window for parents to understand their children. "If parents can read their children's micro blogs, they'll know their thoughts, thus leading to better communication and solutions to problems," he said. He also gives some tips for kids.
　　---Don't micro blog for more than one hour a day.
　　---Never micro blog in class.
　　---Try to talk face to face with people from time to time.
　　---Be critical*. Don't trust all the messages on a micro blog.
