Learning how to write is like taking a course in public speaking. I’ d ask whether anyone in class had ever taken such a course. Invariably a few hands would go up.
“What did you learn in that course?” I’d ask.
“Well, the main thing was learning how to face an audience ... not to be inhibited( 拘谨 )... not to be nervous
Exactly, when you take a course in public speaking nowadays, you don’ t hear much about grammar and vocabulary. Instead, you’ re taught how not to be afraid or embarrassed, how to speak without a prepared script, how to read out to the live audience before you. Public speaking is a matter of overcoming your long-standing nervous inhibitions.
The same is true of writing. The point of the whole thing is to overcome your nervous inhibitions, to break through the invisible barrier that separates you from the person who’ ll read what you wrote. You must learn to sit in front of your typewriter or dictating machine and read out to the person at the other end of the line.
Of course, in public speaking, with the audience right in front of you, the problem is easier. You can look at them and talk to them directly. In writing, you’ re alone. It needs an effort of your experience or imagination to take hold of that other person and talk to him or her. But that effort is necessary -- or at least it’ s necessary until you’ve reached the point when you quite naturally and unconsciously “talk on paper

A、you have to do a lot of preparation work beforehand

C、 you should know grammar and vocabulary well to accomplish them
D、 both of them have audience

In the United States, 30 percent of the adult population has a 'weight problem'. To many people, the cause is obvious: we eat too much. But scientific evidence does little to support this idea. Going back to the America of 1910, we find that people were leaner than today, yet they ate more food. In those days people worked harder physically, walked more, used machines much less, and didn't watch TV.
Several modern studies, moreover, have shown that fatter people do not eat more on average than thinner people. In fact, some investigations, such as a 1979 study of 3, 545 London office workers, report that, on balance, fat people eat less than slimmer people.
Studies show that slim people are more active than fat people. A study by a research group at Stanford University found the following interesting fact:
The more the man ran, the greater loss of body fat.
The more they ran, the greater their increase in food intake.
Thus, those who ran the most ate the most, yet lost the greatest amount of body fat.
1、What kind of physical problem do many adult Americans have?____
A、They are too slim.
B、They work too hard.
C、They are too fat.
D、 They lost too much body fat.
2、Based upon the statistics given in the article, suppose there are 500 adult Americans, about how many of them will have a 'weight problem'?____
A、 30.
B、 50.
C、100.
D、150.
3、Is there scientific evidence to support that eating too much is the cause of a 'weight problem'?____
A、Yes, there is plenty of evidence.
B、Of course, there is some evidence to show this is true.
C、There is hardly any scientific evidence to support this.
D、We don't know because the information is not given
4、In comparison with the adult American population today, the Americans of ____.
A、ate more food and had more physical activities
B、ate less food but had more activities
C、 ate less food and had less physical exercise
D、had more weight problems
5、What have modern medical and scientific researches reported to us?____
A、Fat people eat less food and are less active.
B、 Fat people eat more food than slim people and are more active.
C、 Fat people eat more food than slim people but are less active.
