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. This was necessary 35 astronauts would have to look for rocks on the moon. They would try to find rocks which might help to tell the 36 of the moon. 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. They learnt how every 43 of a space-ship and its instruments work. They also learnt every detail of ground-control 44 .
In a word, to be chosen as an astronaut. One must be in good health, 45 in science and good at piloting.

(答案→)B 解析：【小题1】句意“在26岁和35岁之间进行筛选”，故between...and容易误选为at。At the age of...在某人多少岁时。【小题2】句意为：他们是有经验的，老练的。在这里old不是岁数的意思比experienced 更贴切。【小题3】上文中的many相对应。句意为：其他人是拥有的两个或三个学位的科学家。【小题4】因为是航天可能会深陷于危险之中，同用in danger.【小题5】根据下文人们都很珍惜这次被选中的机会，在兴奋和危险之间，他们都敢于冒险，不会拒绝这份冒险的工作。注意此处用了一个疑问句。accept 主观接受receive 客观接受offer主动提供【小题6】But, 但是，他们更看重后者。根据上文“任何人都不会拒绝这份令人激动的工作”可知。【小题7】被选中的飞行员的身体健康状况非常重要。根据上下文多次提及Pilot可知。【小题8】只有身体条件符合的才能被选中。最后一段One must be in good health可知。【小题9】根据下文They studied the star and the moon, and they also studied geology, the science of rocks.学习天体，地理等可知，必须学习很多相关的课程。Ways 方面，欠具体。【小题10】前后句构成因果关系，学习岩石科学知识很必要，因为宇航员在月球上必须寻找岩石。for表补充说明的原因; since表显而易见的原因，“既然”。【小题11】根据岩石构成以辨别月球的年代。Background背景【小题12】飞行员们也在特殊直升机上进行模拟训练。Train 训练 show展示【小题13】直升机的垂直下降为月球上的真实着陆提供了经验。 straight 径直的，径直地，形容词副词directly 直接地，副词【小题14】Really，真实情况。possibly 可能主语为物 likely很可能主语可以是人或物 actually 实际上【小题15】他们也会被教授一些太空中的已经知道的事实。Well-known 著名的 unknown 不为人所知的【小题16】他们拜访设计太空飞船和火箭的科学家。Them指的是the technical details of the spaceships and rockets，当然是科学家设计的。draw 画的 produce产生 make制作【小题17】他们也拜访生产飞船和火箭的工厂。【小题18】他可以了解太空船和其设备的每个部件是如何运行的。【小题19】他们也要学习基本操作系统的每个细节。【小题20】一个宇航员必须身体健康，精通航天科学，并且擅长飞行技术。well-done干得好的 well-fed 营养充足的 well- kept 保存完好的 well-informed熟悉的，博学多

你的回答很对
