    It is difficult for the parents of every family to teach their children to be responsible (有责任的) for housework.

    The Shatian School in Shanghai is making its students do housework for their parents. The third graders(三年级学生) must learn how to cook and clean, sixth graders do the laundry(洗衣服) and seventh and eighth graders cook balanced meals with 15 yuan.

    Many parents think it's a good way for children to try housework but they don't know how to do it at home. With the following ideas, you really can get your children to help at home.

    If you want to make your children think that they can do everything quite right, please don't always scold(批评) if them but give them lots of praise at home. Talk more about what they did right, not about what they didn't do. If your child finishes some difficult work, give him or her a Sunday trip or a ball game with Dad as a reward.

   Why doesn't everyone laugh at the same joke?

Have you ever had lucid (清醒的) dreams? Recent studies suggest that the number of people having them is on the rise. Someone having a lucid dream realizes they are dreaming and may from then on" direct" the action, or they may simply " watch" the dream unfold. The sense of awareness (知道) makes it different from a dream that is simply very lively and true to life. And although the description may seem strange, the process is far from alien to many of us.

Studies suggest that the number of people in the Western world experiencing lucid dreams, which happen once in a while, has risen by between 10 and 40 per cent since the 1980s. Today, they are so common that about one in eight of us will have one in our lives. But still, little is known about what causes them or what is behind the rise.

Research carried out at the respected Harvard University in the US shows that the brain is working hard during lucid dreams. In fact, the level of the mental (精神

的) activity in some parts of the brain is similar to that of a person who is awake. Lucid dreamers seem to share certain personal characters. For example, in general they are quite creative. They are also good at digging deep into problems and going out of their way to solve them. Furthermore, they always believe in personal responsibility rather than letting society carry the can.

Our nightmares (噩梦) may show our waking worries, with the five most common ones-- falling, being run after, feeling disabled, being late and the death of a loved one. Men are more likely to have nightmares about fights or being fired while hair and tooth loss appear more in women's nightmares-perhaps showing worries about losing their looks. Research has also found that women have more nightmares than men. Their dreams are also scarier and more unforgettable.

Mobile phones are becoming more and more popular not only with adults but also with students. However, they also have become a problem for middle schools in the last few years.

Some children have got mobile phones as Christmas or birthday gifts, and more will ask their parents to buy phones for them.

Many students like mobile phones because they are easy and quick. Some parents feel it convenient because they can get in touch with their children. Some teachers think using mobile phones is a distraction(分心的事)to students during school hours and mobile phones also give them much trouble in their classrooms. Sometimes students send phone messages to cheat(作弊)during exams. A new study says that some teenagers even hurt their fingers because of the over-use of mobile phones. They keep using mobile phones for more than ten hours during a day.

Many teachers suggest that students should not have phones at school, but if there is a good reason, they can leave their phones at the school office. Many people think they understand why parents would want their children to have them, but they agree school should let the students know when they can use their mobile phones.
