Looking forward to your reply.
It’s necessary to revise(复习) after lessons so that you can really understand, remember and use what you have learned. It is also important to revise before exams. 1.
Find Your Place. To revise for an exam, you must first find a quiet and relaxing environment. 2. It should also be a place where you will not be disturbed.
Take Your Time. It’s a good idea to make revising part of your weekly routine. The best way to do this is to revise every school day. 3. Make sure that you study for no more than two hours every time, and that you take a little rest every half hour or so. This will keep you fresh and able to take in information.
Stay Organized. 4. If you are taking notes, organize them by subject, topic and date. That way when you have an exam, you can easily find the right notes to study to help you prepare.
5. At the end of every revision, review your notes carefully to check that you have understood what you have learned. You may also consider writing out revision cards. You can then use these as summary of the subjects that you have learned.
A.Get Ready.
B.Check Your Progress.
C.It takes time to learn a new language.
D.But don’t revise for too long at a time.
E.Here is some advice on how to revise well.
F.A place where you feel comfortable works best.
G.It is helpful to set up a system so you are organized.
Nao, the first robot able to show feelings, has been created by a European research team. When Nao is sad, he lowers his head and looks down. When he’s happy, he raises his arms for a hug. Nothing is out of the ordinary, except that Nao is a robot.
“We’re modeling the first years of life,” says Lola Canamero, a computer scientist at the University of Hertforshire. “The feelings are shown through physical gestures and body movements rather than facial or verbal (言语的) expressions.”
In the future, says the scientist, robots are likely to act as companions, provide support for old people, and help people shop online. In such uses, the display of feeling will be important in making the interactions (交往) more natural and comfortable.
Nao has been programmed to copy the emotional skills of a one-year-old child. It can memorize faces, and knows the basic rules of good and bad. Based on these it can decide how to react to what is going on. The actions going with each feeling are pre-programmed, but Nao decides for itself when to display them.
Nao is also programmed to have different personalities. A more independent robot is less likely to call for help when exploring a room, while a more fearful robot will show distress if it finds something in the room that may be harmful.
Canamero’s team will take its emotional programming forward into medical applications. Part of the project will look at ways to use robots in hospitals to support the roles of doctors, nurses and parents. Children might find that a small, friendly-looking robot that can understand their emotional states makes them less anxious. “We want to explore different roles—the robots will help the children to understand their treatment and explain what they have to do. We want to help the children to control their anxiety.” she says.
