“Imagine you are walking along the road. Suddenly you fall over and all the passers-by burst into laughter. You feel very  36  and think the world is laughing at you . But in fact, five minutes later, they have  37   it ever happened.” The other day when I came across these words in an article, I didn’t agree with the  38  .

The author thinks the best thing to do in this kind of  39  is to pretend nothing has happened, and so avoid  40  trouble.

I admit that we should keep  41  because “Your tears will only remind others of what happened, while your  42  can let them forget it.” But this is far from satisfactory. We should do 43  to make things better.

I used to be a(n)  44  girl and not very good at maths. Our new maths teacher asked me a question and I still remember how I hung my head in  45 when I couldn’t answer it.

“If you don’t know the answer, just tell me.” the teacher said, “If you don’t how can I know   46  you know the answer or not?” All of my classmates burst into laughter. My face turned red but the teacher  47  me to go to the blackboard and  48  what I knew. If I had  49  the words in the article, I would have given up. But I tried my best. And to everyone’s  50 , I succeeded! The teacher smiled and said, “Well done! I  51  you could do it!”

Since then, I have become active in maths as  52  as in other subjects. I used to think doing maths exercises was a waste of time. But now, I know  53  I do can make things better. Everyone is the  54  of his own fate.

If we make mistakes, we should take on an active 55  . Laugh, and the world laughs with you; weep(哭泣), and you weep alone.
