    There once was a wise man who was very respected for his wisdom. This great man was called the Wise Circle Maker. His people believed that he had special powers to make it rain.

    But the Wise Circle Maker did not know everything about life often, when he saw things that he did not understand, he would ask questions, hoping to find the answers.

    One day, he noticed a man panting a fruit tree. He asked the man, "When will this tree bear fruit? How long will it take?"

    The man said that it would take 70 years for fruit to come to the tree.

"And how old are you now?" asked the Wise Circle Maker.

    "I am almost 50 years old" replied the man.

"And do you think you will live to taste the fruit from this tree?" asked the Wise Circle Maker.

    "I am already old and will never taste the fruit from this tree I plant. But when I was born, I saw many fruit trees like this planted by my father, and his father. And I ate the fruit from those trees." replied the man.

    "This tree is for my children, my grandchildren and for their children too. They will taste the fruit of this tree. That is why I am planting it not for me, but for them."

The Wise Circle Maker was impressed. He could easily see the meaning He walked away happily, knowing that he still had much to learn about life.

Kanu and Timo are brothers. They like playing soccer very much. They often play it with their friends after school.

One day, Mom asks them to buy some eggs so she can make （做） dinner for the family. When the brothers make their way to the store, they see （看到） some of their friends playing soccer on a field （运动场）.

"Let's play soccer for a short time （一会儿） first, and then go to the store," Kanu says to Timo.

Timoagrees. Then the brothers go to the field and play with their friends. They have a lot of fun and lose track of time （忘记时间）. "Oh, no, we have to buy eggs now."

Kanu and Timo run to the store, buy some eggs and go home quickly （迅速地）. "Sorry, Mom. We are late," the brothers say. "We play soccer and lose track of time."

"Boys, it's OK, But next time, do important work （重要的工作） before （在……之前） playing, OK?" Mom says.

A US high school with only 200 students is producing some of the world's best technology. 

Students at this school made cars with improved fuel efficiency(燃油效率) and other inventions, too. And now, the students are designing a washing machine for outer space. They hope it will be accepted by NASA or us. 

NASA asked for ideas through ifs HUNCH program, which is short for "High School United with NASA to Create Hardware". Braham Area High School is one of the 100 schools in the program. 

The challenge is to come up with a good way to wash clothes on long-time space tasks, where air and water don't mix and soap can't be used. On shorter space tasks, astronauts simply throw away their dirty clothes. For longer tasks, a different solution is needed. 

The team has already built a system using a series of pumps(泵) and vacuum chambers(真空室)，but NASA were afraid that it might not be durable(耐用的). 

The washing machine isn't the only NASA project Brahma students are working on. They're also designing and building a track system to hold equipment. NASA said it plans to use their system. 

They're also designing an automated(自动化的) feeding system for space mice. NASA regularly takes mice into space as test subjects. 

"To get a kid to do something that they never thought they could do, that's really great! " said Luke Becker, the school's technology teacher. "There are kids who never planned to do anything in technology until they had these chances. "

Boys and girls, we have some interesting and fun things for you this term. Have a good time.

 It's said that about 4% of people sleepwalk(梦游) at night during their lives. That is, you or some of your families and friends have done so. Sleepwalking happens while one is sleeping. Sleepwalkers walk slowly around the house, say something and then go back to sleep. Their eyes are usually open and look right at you as if they were awake. The next day, they remember nothing when they are asked about what happened the night before.

 Sleepwalking is a common problem for many children from 4 to 12 years old. It could run in family. If one of the parents is a sleepwalker, their children may be, too. Scientists still don't know why people sleepwalk, but they find common facts that may lead to sleepwalking. For example, if one is under stress, gets sick or doesn't have enough sleep, he or she will have more chances to sleepwalk. Sleepwalking itself isn't bad, but it may make sleepwalkers get hurt because they are in fact"sleeping" and don't know what they are doing. It is important to keep sleepwalkers from falling down, running into something and even walking out to drive.

 What can we do for sleepwalkers? First, try not to wake up a sleepwalker because it may make him or her scared. All you have to do is to show the sleepwalker the way back to bed. Second, close the windows and doors to stop sleepwalkers from going out. Third, keep any things that may hurt the sleepwalkers away. Remember, if you find someone sleepwalking, the most important thing is to make sure he or she is safe.
