       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

     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

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.
