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 notice the loudness, the quality and the musical note of his voice always change according to what he is talking about.
The fact that a good teacher has some of the gifts(天赋) 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(预先). 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 take 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 in 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. 
【小题1】The word “audience” in the third paragraph means ________.

What would happen if you tried to blow a soap bubble in freezing weather? Would it freeze solid(固体) and fall to the ground? Would you have to hit it to break it? These questions happened to me on a cold winter day. It was too cold to play in the snow, but it was a perfect time to experiment with blowing frozen bubbles.

To blow frozen bubbles, I used dishwashing soap and a drop of glycerin（甘油） to make it even better. I chose a place out of the wind, and blew bubbles the same way I always do. I watched to see what would happen. Here’s what I learned.

If the temperature is low enough, the skin of the bubbles frosts over (结霜), becoming cloudy instead of clear. And what about those rainbow swirls（旋转） you see in soap bubbles? The rainbow colors stay even when the bubbles frost, but they don’t swirl anymore. The bubbles still stay in the air. They don’t fall to the ground any faster than they would on a warm summer day.

When these frozen bubbles break, they don’t turn into small water drops as summer bubbles do. They turn into flashing rainbow confetti（碎屑） and move slowly to the ground. Sometimes a frozen bubble will roll across the snow without breaking. If nothing disturbs the bubble, it may stay there for a long time. Sometimes I could catch a bubble and hold it until the heat of my hand made it pop.

I learned another thing about blowing frozen bubbles. It’s so interesting that I want to try it again next year.

A．to learn how to do a science experiment

B．to show the experiment of blowing frozen bubbles

C．to discover games that are fun to play in the snow

Basketball is still a young game. It's over a hundred years old. In the winter of 1891, a certain college was having some trouble with its boy students. The weather was bad and the students had to stay indoors. As they couldn't play outdoors, they were unhappy, and some even got into fights from time to time.

　　Some of the teachers, at the college asked Dr. Naismith to invent a game so that the students might have something to play with. It was not easy to invent such a game because it had to be played indoors , and the court (球场) was not very large.

　　Dr. Naismith thought for a few days and invented a kind of ball game. It was a fast, wonderful game with much moving and passing of the ball. It was played between two teams. To make a score , the ball had to be thrown into the basket ten feet(英尺) above the floor on the wall . At each end of the court there was such a basket. At first, Dr. Naismith wanted to throw the ball into a box. As he could not find boxes of the right size, he had to use fruit baskets instead. That is how the game got its name.

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, pleasant 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 doesn’t 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.
