Parents often believe that they have a good relationship with their teenagers (青少年). But last summer, Joanna and Henry noticed a change in their older son. Suddenly he seemed to be talking far more to his friends than to his parents. "The door to his room is always shut," Joanna noted.
Tina and Mark noticed similar changes in their 14-year-old daughter. "She used to cuddle up (蜷伏)with me on the sofa and talk," said Mark. "Now we joke that she does this only when she wants something. Sometimes she wants to be treated like a little girl and sometimes like a young lady. The problem is figuring out which time is which."
Before age 11, children like to tell their parents what's on their minds. "In fact, parents are first on the list," said Michael Riera, author of Uncommon Sense for Parents with Teenagers. "This completely changes during the teen years," Riera explained. "They talk to their friends first, then maybe their teachers, and their parents last."
Parents who know what's going on in their teenagers' lives are in the best position to help them. To break down the wall of silence, parents should create chances to understand what their children want to say, and try to find ways to talk and write to them. And they must give their children a mental break, for children also need freedom, though young. Another thing parents should remember is that to be a friend, not a manager, with their children is a better way to know them..

“Human influenza viruses can survive and be infectious for several days when they are deposited on banknotes,” according to the latest study by Yves Thomas and his colleages in Switzerland. Scientists put different types of flu virus onto Swiss franc notes and found that they could survive from a few hours to more than a week. The results depended on the type of flu virus.
According to the study, Swiss-banknotes are mostly cotton covered by a nonporous resin(无孔树脂). Banknotes from other countries may be composed of different materials, and this could affect viral transmission. “Whether similar results would be obtained with banknotes from other countries and with different characteristics needs to be studied.” the authors wrote. In an interview with Reuters, Thomas said. “Our studies have convinced us that it is possible to catch the flu from banknotes, but the chances are very, very small and there is no cause for concern among the gneral population,” To be sure, many kinds of frequently touched surfaces could temporarily hide the flu virus. Broadly speaking, scientists consider the risk of transmission in this way to be low. Particularly if hand-washing and other hygiene measures are practiced.
Three things must happen for a flu virus to be transmitted from one person to another via money. First, a person who is infected with the flu virus must sneeze or cough onto the banknote. Next, an uninfected person would need to touch the money while the virus si still present. Finally, that person would need to put his hand in his mouth or pick his nose, says Thomas. The best defense against infection: follow public health guidelines and wash your hands frequently.

To be a good teacher, you need some of the gifts of a good actor; you must be able to hold the attention and interest of your audience; you must be a clear speaker, with a good, strong, pleasing voice which is fully under your control; and you must be able to act what you are teaching, in order to make its meaning clear.
Watch a good teacher, and you will see that he does not sit still before his class:he stands the whole time he is teaching; he walks about, using his arms, hands and fingers to help him in his explanations, and his face to express feelings. Listen to him, and you will hear the loudness, the quality and the musical note of his voice always changing according to what he is talking about.
The fact that a good teacher has some of the gifts of a good actor doesn’t mean that he will indeed be able to act well on the stage, for there are very important differences between the teacher’s work and the actor’s. The actor has to speak words which he has learnt by heart; he has to repeat exactly the same words each time he plays a certain part, even his movements and the ways in which he uses his voice are usually fixed beforehand. What he has to do is to make all these carefully learnt words and actions seem natural on the stage.
A good teacher works in quite a different way. His audience takes an active part in his play：they ask and answer questions, they obey orders, and if they don’t understand something, they say so. The teacher therefore has to meet the needs of his audience, which is his class. He cannot learn his part by heart, but must invent it as he goes along.
I have known many teachers who were fine actors in class but were unable to take part in a stage-play because they could not keep strictly to what another had written.
