[单项选择]To be a good teacher, you need some of the gifts of a good actor: you must be able to hold the attention of your audience; you must be a clever speaker, with 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.
The fact that a good teacher has some of the gifts of an 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 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
A. presents
B. cleverness
C. something belongs to a good actor
D. the way a teacher should act in class
[单项选择]Fried foods have long been frowned upon. Nevertheless, the skillet(平底煎锅) is about our handiest and most useful piece of kitchen equipment. Sturdy lumberjacks(伐木工) and others engaged in active labor requiring 4,000 calories per day or more will take approximately one-third of their rations prepared in this fashion. Meat, eggs, and French toast cooked in this way are served in millions of homes daily. Apparently the consumers are not beset with more signs of indigestion than afflict those who insist upon broiling, roasting, or boiling. Some years ago one of our most eminent physiologists investigated the digestibility of fried potatoes. He found that the pan variety was more easily broken down for assimilation than when deep fat was employed. The latter, however, dissolved within the alimentary tract more readily than the boiled type. Furthermore, he learned, by watching the progress of the contents of the rate of digestion. Now all this is quite in contrast with "authority." Volumes hav
A. fried foods have long been frowned upon

[单项选择]Wherever people have been, they have left waste behind, which can cause all sorts of problems. Waste often stinks, attracts vermin and creates eyesores. More seriously, it can release harmful chemicals into the soil and water when dumped, or into the air when burned. And then there are some really nasty forms of industrial waste, such as spent nuclear fuel, for which no universally accepted disposal methods’ have thus far been developed.
Yet many also see waste as an opportunity. Getting rid of it all has become a huge global business. Rich countries spend some $120 billion a year disposing of their municipal waste alone and another $150 billion on industrial waste. The amount of waste that countries produce tends to grow in tandem with their economies, and especially with the rate of urbanization. So waste firms see a rich future in places such as China, India and Brazil, which at present spend only about $5 billion a year collecting and treating their municipal waste.
