试说出采用弹性系数法进行预测的特点。

答案

参考答案:用弹性系数法进行预测的优点是:简单易行,计算方便,成本低,需要的数据少,应用灵活广泛。其缺点是:(1)分析时只考虑两个变量之间的关系,而忽略了其他相关变量所能产生的影响,因此带有一定的局限性和片面性;(2)弹性系数可能随着时间的推移而变化,因此分析的结果在许多情况下显得比较粗糙。

       Some problems are difficult to solve!  But there are a lot of number expressions that can help.

For example,if we put two and two together,we might come up with the right answer. We know that

two heads are better than one. It is always better to work with another person to solve a problem.

       Sometimes we can kill two birds with one stone. That is, we can complete two goals with only

one effort or action. But we must remember that two wrongs don't make a right. If someone does

something bad to you,you should not do the same to him.

       If you are going out with your girlfriend,or boyfriend,you do not want another friend to go along

on your date. You can just say to your friend:twos company, three's a crowd.

      A young child in school has to learn the three Rs. These important skills are reading, writing and

arithmetic.  These three words do not all start with the 1etter R,but they have the sound of R. Teachers

will give three cheers when their pupils do a good job.

     Some of my friends were confused and did not understand their schoolwork. They were at sixes

and sevens. In fact,they did not care whether they could finish high school. They saw 1ittle difference

between the two choices. But they were really happy when they completed their studies and graduated

from high school. They were in seventh heaven. They were on cloud nine.

     Last year,one of my friends applied for a better job at her office. I did not think she would get it. I

thought she had a hundred to one shot at the job. Other people at her office thought her chances were

a million to one. One reason was that she had been caught catching forty winks(打盹)  at the office. She

slept at her desk for short periods during the day. But her supervisor appointed her to the new job at

the eleventh hour-at the very last minute. I guess her lucky number came up.
