Mom had polio(С¶ùÂé±ÔÖ¢)when she was a young child. One of her legs was larger than the other. Sometimes she would have trouble walking, but she never complained.

Today we can see that many people are cutting ___41___ the trees in the forests. A lot of rich land ___42__ become deserts(ɳĮ).

What will happen ¡¡ 48¡¡ the forests disappear? A lot of plants will die and the animals will ¡¡ 49¡¡ their home. In many places the new farmland will soon look____50____ the old deserts.

Each of us fails from time to time. If we are wise, we accept these failures as a necessary ¡¡31 of the learning process. But too often as parents and teachers we deny this same right to our children. We convey(´«´ï) 32 ¡¡by words or by actions that failure is something to be ashamed of, that nothing but ¡¡33¡¡ performance pleases us.

34 I see a child under this kind of pressure ,I think of Jack. He is a shy, nervous perfectionist. He ¡¡35 answered questions¡ªhe might be ¡¡36 .

I try my best to ¡¡37 his self-confidence. And I repeatedly ¡¡38 ¡¡God for direction. But ¡¡39 changed until midterm, when Mary, a student teacher, came to our classroom.

One day we were working with math problems. Jack had copied the problems with care. 40 with his progress, I left the children with Mary .When I returned, Jack was in tears. He¡¯d missed the third problem.

At that time, Mary got a box ¡¡41 with pencils from the desk we shared. ¡°Look, Jack ! I¡¯ve got something to show you.¡± she said.¡° See these pencils, they belong to Mrs. Green and me. See how the erasers are ¡¡42¡¡ ? That¡¯s because we make mistakes too. But we erase the mistakes and try ¡¡43 . That¡¯s what you must learn to do, too.¡± Jack looked up with ¡¡44 in his eyes---the first time I¡¯d see on his face that year.

Jack gradually believe him that it¡¯s all ¡¡45 to make mistakes ¨C as long as you erase them and try again.

One day, a teacher was speaking to a group of students about how to manage time. He gave such an interesting example that his students would never ¡¡31 .

He put a wide-mouth jar (¹Þ×Ó) on the table. Then he ¡¡ 32 some rocks and carefully placed them into the jar, one at a time. When 33 rocks would fit inside, he ¡¡34 , ¡°Is this jar full?¡±

Everyone in class shouted, ¡°Yes.¡± ¡°Really?¡± The teacher pulled out a bag of small stones. He put ¡¡35 small stones in and shook the jar. The small stones went ¡¡36 into the spaces between the big rocks. He then asked the group¡¡ 37 , ¡°Is this jar full?¡±

¡°Probably not,¡± one of them answered. ¡°Good!¡± the teacher replied. He brought out a box of sand and ¡¡38 some sand into the jar and it went between the rocks and small stones. Again he asked the ¡¡39 question, ¡°Is this jar full?

¡°No,¡± the class shouted. Once more the teacher said, ¡°Good.¡± He poured a cup of water into the jar ¡¡40 it was full. The he asked, ¡°What is the point here?¡± One student ¡¡41 his hand and said, ¡°The point is that if you try really hard, you can ¡¡42 put more things in.¡±

¡°No,¡± the teacher replied, ¡°that¡¯s not the 43 . What I want to tell you is that if you don¡¯t put the big rocks in first, you will never get others in at all. ¡¡44 are the ¡®big rocks¡¯ in your life? Time with your friends, your education or your dreams? Remember to put the 45 in first, or you¡¯ll never get others in at all.?¡±
