It is interesting how NASA(美国航空航天管理局)chose their astronauts for landing them on the moon. They chose men 26 the age of twenty and thirty-five. There were about fifty of them, Many were 27 air pilots. 28 were scientists with two or three degrees. NASA telephoned each man they were going to choose; told him the plans and the 29 they might get in. They then asked him if he was willing to be trained as an astronaut. “How could any man 30 such an exciting job?” One of them said, “Dangerous? Of course. It’s dangerous 31 most exciting”
The health and physical condition of 32 was, of course, very necessary. 33 those in very good health and physical condition were chosen.
While being trained to be astronauts. They went through many 34 . They studied the star and the moon, and they also studied geology, the science of rocks.

They were all 37 to fly in helicopters （直升飞机）。These helicopters landed 38 down to give them some experience of the way the spaceship would 39 land on the moon , They were also taught the 40 facts about the conditions in space. They learnt all the technical details of the spaceships and rockets. They visited the scientists and engineers who 41 them. They visited the factories where they were 42.

Don’t shoot butterflies with guns.
Can you 36 someone running after a butterfly with a gun in his hands? Won’t such stupidity make you burst out laughing? But wait. Stop and consider how often you might have done something 37 .
A hen, Henny-Penny, lived in a forest with many other animals and birds. One fine, sunny morning, she was busy looking for 38 in the ground. Suddenly she let out a frightened cackle (咯咯叫) with wings flapping 39 . A dry leaf had fallen down on her, and she went 40 at whoever she met, “Run, run for your lives; the sky is falling.” The other creatures stopped whatever they were doing. Some ran behind Henny-Penny, screaming warnings with her, while others 41 the unfounded story that the sky was falling.
We all have 42 people like this hen. The rest of us are like the other foolish creatures who didn’t stop to verify (证实) the 43 for themselves. They shoot butterflies with guns. They just will not think for themselves. Why don’t people think for themselves? Often because of laziness, or because they don’t want to be 44 for their way of thinking.
Walking through life 45 is more dangerous than crossing a busy road with eyes closed. Our thoughts should lead us towards the light of wisdom and sense. Our thinking should be high, 46 us to the ranks of the sensible. We have been blessed with reasoning, sensitive minds. Let us make use of them and be 47 of our own minds. Don’t let your mind be enslaved by someone else. Stop, think and then go ahead.

They also know how to 44 full use of the shape of land to 45 sheep. I believe that if wolves were humans, they would be 46 experts good at fighting.

To his 54 , he found the little wolf still wanted to go back with 55 wolves. He bit through the iron chain that limited him. The wolf was 56 and he never gave in, fighting 57 his death. The little wolf died as a glorious fighter.
I was shocked by this kind of 58 wolves are one of the most respected creatures on the earth. I want everyone to look at wolves in a 59 way. They are our teachers.

Changes in the social structure may indirectlyjuvenile crime rates．For example，changes in the economy thatto fewer job opportunities for youth and rising unemployment make gainful employment increasingly difficult to obtain．This results inamong youths and may inlead more youths into criminal behavior.
Families have also experiencedthese years．More families consist of one parent households or two working parents；，children are likely to have less supervision at home than was common in the traditional family．This lack of parental supervision is thought to be an influence on juvenile crime rates．Other noticeableof offensive acts includeexperience or failure in school，theavailability of drugs and alcohol，and the growing phenomenon of child abuse and child neglect．All these conditions tend to increase theof a child committing a criminal act，a direct cause and effect relationship has not yet been established.
