moth come out of the cocoon. On that day a small   2 appeared. He sat and watched the moth
for several hours as the moth struggled to   3   the body through that little hole. Soon it seemed
to stop making any progress. It appeared as if it had    4  as far as it could and it could go no

He took a pair of scissors and cut off the   5___   bit of the cocoon. The   6   then came out
easily. But it had a swollen body and small, shriven (无用的) wings. The man continued to

could have been. Give every opportunity a chance. Leave no room for   20    .
