Adults laugh between 7 and 15 times a day," says Dr Kataria, "Everyone's naturally good at laughing. We want people to feel happy with their lives."

Have you ever heard robot fish? Scientists will put some robot fish into the sea near Spain. These robot fish will help people to detect (探测) the pollution in the water. If the robot fish are able to finish their work successfully, the scientists hope to put them into rivers, lakes and seas around the world.

The fish are about 1. 5 meters long. There will be a detector in their bodies. They can find the sources (来源) of pollution in the water, and then the robot fish will eat part of it. Unlike other robots, they don't need to be controlled by people far away. The robot fish all have an eight-hour battery (电池). They can "swim" in the sea freely and send back information to people on the beach. After their batteries die, they will return by themselves.

There are five robot fish altogether now. Each costs about 29,000 dollars. They are part of a three-year project between engineering company BMT Group and Essex University in southeastern England.

"We invented the robot fish creatively. We hope they can find the changes in the sea water and report back the information," said Professor Hu of Essex University. His team is developing the fish.

Ben, a 14-year-old boy, used to be a lazy boy. In his own words, he hardly did any housework. But now, things have changed. Washing dishes, cooking and making his bed… all of these chores have become a part of his daily life.

This big change is the result of a new program at his school. Starting from last term, Da Zhou No. 1 Middle School has made housework part of its students' homework, in order to improve their life skills.

At the beginning of each month, every student gets a list of housework to do every weekend. Their parents help them keep track(轨迹) of their performance. Some of the tasks are quite specific(具体的), such as cleaning out bookcases, washing cups and cooking food. On holidays like Mother's Day, students are asked to prepare gifts for their mothers.

Wang Yixi, 13, has learned several life skills through the program, including cooking. "I used to be afraid of fire," she said. But she tried her best to surmount her fear and complete cooking tasks.

At the same time, she also learned how tired her mother gets after doing housework every day. On Mother's Day, she made a cake for her mother to show her thanks. "I've begun to better understand my parents and want to help them more," she said.

A wise man was walking from one town to another with a few of his followers, and they happened to pass a lake. So they stopped there to 1 for a while, and the wise man said to one of his followers, "I am very 2. Could you please 3 me some water from the lake?"

One follower walked to the lake 4 the wise man requested(要求). Some people were washing clothes in the water, and right at that moment, several carts(手推车) started crossing the lake. 5, the water become very muddy(泥泞的).

Then he went back and told the wise man that the water was very muddy and not 6 to drink. After they had rested for about half an hour, the wise man again asked the 7 follower to go back to the lake and get him some water to drink. As requested, the follower went to the lake again. This time he found that all the mud had settled(沉淀) to the 8. The water was very 9 and looked fit to drink. So he 10 his water bottle and took it to the wise man.

The wise man took the water bottle and drank, then looked up at the follower. "See what you did to make the 11 clean?" he said. "You let it be for a while and the mud settled down on its own, 12 you could get some clear drinking water. Your mind can also be like that lake when it is disturbed (被搅乱) by something. If you just let it be and give it a little 13, it will most likely settle down on its own 14 being put in any effort at all to 15 it."
