Jim is a boy who thinks a lot and learns a lot. One day when he was passing the elephants, he suddenly stopped. He saw a group of elephants and these big animals had a rope around their front     . The rope was very      , so the elephants could break it easily. But to his surprise,      did not.

Jim saw a trainer near the elephants. Then he walked over and asked him    . “Well,” the trainer said, “When they were very young and much smaller , we used the same       ropes to tie around their legs and, at that age, they were sure they      hold(约束)them. As they get bigger and bigger, thy still believe the ropes can hold them, so they     try to get away.”

Jim thought a lot     that. These animals could break their ropes at any time, but because they       they couldn’t, they didn’t give it a try.

Like the       many of us believe that we can’t do something in our life, just because we didn’t do it successfully in the past.
