There was once a boy who had a temper.His father gave him a bag of nails and told him that every time he lost his temper,he 　1　 hammer a nail into the back of the fence.

The first day the boy 　2　 (drive)37 nails into the fence.Over the next few weeks as he learned to control his anger,the number of nails hammered 　3　 (gradual)decreased.He discovered 　4　 　was easier to hold his temper than to drive nails into the fence.

Finally the day came 　5　 　he didn^,t lose his temper.He told his father and his father suggested that the boy now　 6　 (pull)out one nail for each day so that he was able to hold his anger.The days passed and the boy told his father that all the nails were gone.

The father took the boy 　7　 　the hand and led him to the fence.He said,“Look at the holes in the fence.The fence will never be the same.When you say things in anger，they leave a scar(疤痕)just like the　 8　 on the fence.It won^,t matter how many times you say I am sorry,　 9　 wound is still there.A verbal wound is as bad as a physical one.Friends are very rare.They make you smile and encourage you　 10　 (success).They lend an ear,and always want to open their hearts to us.” 　

　If the population of the Earth keeps on　 1　 (increase)at its present rate,there will?　 2　 (event)not be enough resources left to support life on the planet.By the middle of the 21st century,if present trends continue,we　 3　 (use)up all the oil that drive our cars,for example.Even if scientists develop new ways of feeding the human race,the crowded conditions on Earth will make it　 4　 (necessity)for us to look for somewhere else.But　 5　 of the other planets in our solar system are capable of supporting life at present.One possible solution to the problem,?　 6　 ,hasrecentlybeen suggested by an American scientist,Professor Carl Sagan.Sagan believes that　 7　 the Earth^,s resources are completely?　 8　 (exhaust),it will be possible to change the atmosphere of Venus and　 9　 create a new world almost as large as Earth itself.Something is difficult.Venus is much hotter than the Earth.?　 10　 ,there is only a tinyamountof water there.
