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.

What is the text about?

Removing the sleeve(封套), you will find a book that is entirely white, except for the names of its author and subject in elegant black type on the cover. It is the perfect design for the biography of a man who insisted that even the insides of his products be perfectly constructed, and that his factory wails flash in the whitest white.

The cover was the only part of the book Steve Jobs wanted to control, writes Isaacson in his introduction. Though Mr. Jobs pushed the biographer of Albert Einstein and Benjamin Franklin to write in his own way, generously allowing the writer more than 40 interviews, this book offers quite a different view of Mr. Jobs, who won much praise from his fans after his death on October 5th at the age of 56.

As a biographer of Albert Einstein and Benjamin Franklin, Mr. Isaacson knows how to celebrate long-dead genius, but he claimed that "Steve Jobs" would not be entirely praiseful words. The picture he paints, particularly in the first half of this book, is not nice. Mr. Jobs emerges as a controlling and often cold-blooded character. A child of the 1960s counter-culture (反主流文化), he hated, materialism and lived in simply furnished houses ( in part because he was too particular about furniture). But when Apple went public in 1980, he refused to give any share to Daniel Kottke, a Iongtime supporter and soul mate from college. "He has to abandon the people he is close to," observes Andy Hertzfeld, an early Apple engineer.

Mr. Jobs was undoubtedly possessing an extraordinary ability to attract others and inspire a kind of faith that could not be questioned. But also he could be cold and cruel. If he disapproved of an employee's work, he often shamed him. "This is who I am," he once said after being challenged,"and you can't expect me to be someone I'm not. " This disgusting personality wasn't always helpful,but it served a purpose, writes Mr. Isaacson, many would "end their chain of horror stories by saying that he got them to do things they never dreamed possible. "

Mr. Isaacson treats "Steve Jobs" as the biography of record, which means that it is a strange book to read so soon after its subject's death.

Thirty-two people watched kitty Genovese being killed right beneath their windows. She was their neighbor. Yet none of the 32 helped her. Not one even called the police. Was this in gunman cruelty? Was it lack of feeling about one’s fellow man?
Not so, say scientists John Barley and Bib Fatane. These men went beyond the headlines to probe（探查） the reasons why people didn’t act. They found that a person has to go through two steps before he can help. First he has to notice that is an emergency(紧急情况).
　　Suppose you see a middle-aged man fall to the side-walk. Is he having a heart attack? Is he in a coma （昏迷） from diabetes（糖尿病）? Or is he about to sleep off a drunk?
Is the smoke coming into the room from a leak in the air conditioning? Is it steam pipes? Or is it really smoke from a fire? It’s not always easy to tell if you are faced with a real emergency.
　　Second, and more important, the person faced with an emergency must feel personally responsible. He must feel that he must help, or the person won’t get the help he needs.
The researchers found that a lot depends on how many people are around. They had college students in to be tested. Some came alone. Some came with one or two others. And some came in large groups. The receptionist started them off on the tests. Then she went into the next room. A curtain divided the testing room and the room into which she went. Soon the students heard a scream, the noise of file cabinets falling and a cry for help. All of this had been pre-recorded on a tape-recorder.
Eight out of ten of the students taking the test alone acted to help. Of the students in pairs, only two out of ten helped. Of the students in groups, none helped.
In other words, in a group, Americans often fail to act. They feel that others will act. They, themselves, needn’t. They do not feel any direct responsibility.
Are people bothered by situations where people are in trouble? Yes. Scientists found that the people were emotional, they sweated, they had trembling hands. They felt the other person’s trouble. But they did not act. They were in a group. Their actions were shaped by the actions of those they were with.
