The Internet has become part of teenagers’ (十几岁的) life. A new report shows that 38 percent (百分之……) of 3,375 students use the Internet often.

Most of the students get useful information for their studies, but some are not using it in a good way. Many students are playing online games too much. Some even visit some unhealthy websites. A teacher from Beijing Yinghua Middle School, Hong Ying warns (警告) that something bad can happen if young people spend too much time on the Internet. She said that one of her students used to be good at school. But when he started visiting unhealthy websites,he hurt a girl by cheating online. At last the police caught him and sent him into the prison (监狱).

In order to help young people use the Internet safely, some schools in Shanghai find a good way. The schools provide a textbook (教科书) for the students. The book uses real examples to teach students about good ways of using the Internet. Teachers and parents all think the book is good.

Hong said that the book will help students keep away from the bad behaviors (行者) of using computer. The book will teach students how to be a good person (人) in the online world.

If you have ever talked about your dreams with your friends, you will find some of your friends don’t remember their dreams, while others can tell their dreams very clearly. Why do people remember dreams differently? The answer is simple: they are two different types of dreamers -low-recall dreamers and high-recall dreamers.

High-recall dreamers reported they remembered their dreams almost every day while low-recall dreams said they only remembered their dreams once or twice a month. Perrine Ruby, a lead scientist at the research center in Lyon, studied 41 people(21 high-recall dreamers and 20 low-recall dreamers)and recorded their more active in high-recall dreamers .This was true both when they were sleeping and awake .This area of the brain is to collect information from the outside world. This means that high-recall dreamers are more sensitive to what is happening around them. For example, when they are awake, they respond(作出反应)more strongly to bearing their own names. When they are sleeping, they can be woken up more easily by sounds and movements

This is not hard to understand. Just try to think of your own sleeping experience. If you’re worried during the night, you are easy to remember your dreams, but if you sleep well, you remember very little in the morning This is because "you never get a chance to remember”

As another research project at the University of Turku in Finland showed, what you dream can also affect our memory. Negative(消极的) dreams are more likely to be recalled than ordinary dreams. Nightmares(噩梦)are often recalled because they are negative, and such dreams cause fear.
