1,return就是回来的意思,加back就重复了.turn可以加back,意思一般为归还.
2,return后已经有介词from,再加个介词back干什么?
应该选A.

假设你是一个在太空站外进行空间行走的宇航员而这时你喷气发动机组件燃料耗尽了.你怎么用你这个空的喷气发动机组件使你回到太空站?

is　affected by 受...影响
affect, 动词,一般指 影响的过程.
effect, 名词,也可以是动词.但一般情况下作名词, 指已经知道的影响.此处“被失重的问题影响”

are no

答案：C.
翻译：--中国航天员杨利伟已经在这儿了.--我还以为他要到明天才能来呢.
1.答者已经听到了杨利伟来了的消息,所以“他认为杨利伟会明天来”中的“认为/以为”这个动作（think）肯定是听到这句话之前所发生的（因为他现在肯定不会这样认为了）,所以此题关键在于答语中的think一定要用过去式,排除用现在时的答案AD；
2.如果用B的话,则说明楼主对until的用法把握不够.
until如果用在肯定句中,意思是“（一直做某事）直到（什么时候）”,就是说谓语动词所表示的动作/状态必须是能够延续一段时间的,但是come却是一个瞬间性动词（表示瞬间完成的动作）,所以B也错误.
如：I worked until 23:30 last night.（work就是延续性动词）
昨晚我一直工作到十一点半.
3.不过,until如果用作否定句中（即not...until...）,意思是“直到（什么时候）才（做某事）”,否定句中not后面的动词又必须是瞬间性动词,而come恰好符合这一点.
再如：I didn't come here until 23:30 last night.（come就是瞬间性动词)
昨晚我直到十一点半才来到这里.
而C中的not...until...的not被提前到主句didn't think中.
而且从句之所以用过去进行时表示过去将来时（was coming）,是因为当初答者认为的时候,杨利伟并没有来,所以“杨利伟来”在当时（答者认为的时候）并没有发生,即为过去将来时.
4.此题考查句子的隐含时态,not...until...和until的区别等.

第一、二、三、五个可能是可数名词,我现在是小学,不太清楚可数名词与不可数名词.

是被动吖、你想吖~宇航员被期待、肯定是被其他人期待的嘛
其他人可以说是人们、大家、民众、
翻译是民众、人们、大家希望宇航员马上登上月球.

长城是一个伟大的奇观,是宇航员从月球无需望远镜就看得见的

I willwon'twill make(个人认为题目中的“make"应该是打错了,应该是cake）will play
Where will

I hope to be an astronaut.

D
已经被忽略多年的宇航员一下子变得非常有名气
此处考查非谓语,结合后面the astronaut做主语,前面该用被动句型,for many years,完成时态常与一段时间连用

D
强调句 succeed in doing sth.

一名宇航员必须具备许多不同的素质.

小题1:Space Tourist
小题2:So far, the Russians have not charged the U.S. for trips to the ISS.
小题3:bring in some badly needed cash/earn some money
小题4:Anyone who is interested in space travel, can pass the necessary training, and, above all, can afford it.
小题5:发现号宇宙飞船在今年早些时候进行了一次飞行,但考虑到安全问题,这一项目中途停止。


小题1:通读全文可知文章讲述的是太空游客。
小题2:题原句是俄罗斯没有向美国收费，那么只有So far, the Russians have not charged the U.S. for trips to the ISS.
小题3:根据上文的been short of money in recent years可知俄罗斯缺少钱，那么需要挣钱。
小题4:推理题。根据文章第四段内容2,3行可知offers an ISS trip to who can afford it and pass the necessary training.
小题5:发现号宇宙飞船在今年早些时候进行了一次飞行,但考虑到安全问题,这一项目中途停止。

好的.稍等

宇航员
当然可数

哈哈哈,我高中的时候也经常遇到此类模棱两可的题目,有时候老师也说不清,我也很少让同学解释.不过这个题目确实可以理性思考的.challenge of man＝man’s challenge （这个没问题哈）和challenge for man区别了哈,上句“exploring outer space”,强调了人类主动探索太空,所以of就能说得通了哈.比如再举一个例子哈,地震无情,对人类来说是一次挑战,这种情况下“对”就要用for.希望我不算口齿不清…………

1.一位宇航员使用机械臂空间shuttle'e从太空拿起了一个1800磅的卫星
2.把它写在纸上
好的,我马上去做
3.我可以用一下你的钢笔吗?
当然.给你
4.但愿这是回家的时候了.
我完全同意
5.在我的花园的角落里有一棵苹果树,每天都有鸟在那儿唱歌

orn into a teacher's family,yang liwei is a astronaut 整体翻译没有错,但是这两句话翻译出来前后没有什么联系 出身在教师家庭,杨利伟是个宇航员~宇航员和出身在教师家庭有什么关系呢?

选D.主语从句

.2 hours

1 选B the space是专用说法 意义是宇宙 前一个空呢，stars没有特指哪些星星 说白了就是满眼全是星星 是泛指所有星星 所以不必加the 如果还是不太明白 你吧the astronaut saw nothing but the space放前面，后面跟besides stars 是不是觉得更能明白呢
2 the + adj = n 表示一类人 如the poor 为穷人 the...

C
主语是航天员做很多的试验这个事件,因此谓语要用单数.
think of.意思是考虑,认为.
在这个句子里,think of后面应该是“The astronaut did many experiments in the spaceship”,而which正好是这句话的替代品,所以of应该提前.

When will our...land on the moon?
How soon will our...land on the moon?

[tr]发清音.因为只有当s+清音重读时,清音才浊化.
astronaut里是第一个音节a重读,所以[tr]是清音

1what will you do in the future?
i will be an astronaut
2where will rockets fly to?
it will fly rockets to the moon
3where will astronaut live?
he will live on a space station
没有主语你怎么抄的题啊还是老师脑子进水了啊?

What did they three astronaut take to go the space?

China hopes to send an astronaut to the moon

special应该

答案是D.因为be of help就相当于helpful.而A中的is用错了,因为which指的是experiments,是复数,所以is用单数,明显错了.

1-5 BACBA

对,一般都是succeed in doing sth,成功做某事,没有succeed on这个短语,估计你的答案错了.

这是中国宇航员在太空的第一步,应该填walking,是名词

这句话想强调的是在将来的特定的那个时间点会发生什么事,所以用将来进行时.若用一般将来时的话,则泛指将来某个时间会发生的事,就起不到强调作用了.但本句中没有把时间点体现出来,时间点应该在上下文中显示出来了吧?...

原文：Astronaut Jim Voss has enjoyed many memorable moments in his career,including three space flights and one space walk.But he recalls with special fondness a decidedly earthbound(为地球引力所束缚的) experience in the summer of 1980 when he participated in the NASA ASEE Summer Faculty Fellowship Program.Voss,then a science teacher at West Point,was assigned to the Marshall Space Flight Center's propulsion lab in Alabama to analyze why a hydraulic fuel pump seal on the space shuttle was working so well when previous seals had failed.It was a seemingly tiny problem among the vast complexities of running the space program.Yet it was important to NASA because any crack in the seal could have led to destructive results for the astronauts who relied on them.
“I worked a bit with NASA engineers,” says Voss,“but I did it mostly by analysis.I used a handheld calculator,not a computer,to do a thermodynamic(热力学的) analysis.” At the end of the summer,he,like the other NASA ASEE fellows working at Marshall,summarized his findings in a formal presentation and detailed paper.It was a valuable moment for Voss because the ASEE program gave him added understanding of NASA,deepened his desire to fly in space,and intensified his application for astronaut status.
It was not an easy process.Voss was actually passed over when he first applied for the astronaut program in 1978.Over the next nine years he reapplied repeatedly,and was finally accepted in 1987.Since then he has participated in three space missions.The 50-year-old Army officer,who lives in Houston,is now in training for a four-month mission as a crew member on the International Space 原文：Station starting in July 2000.
Voss says the ASEE program is wonderful for all involved.“It brings in people from the academic world and gives NASA a special property for a particular period of time.It brings some fresh eyes and fresh ideas to NASA,and establishes a link with our colleges and universities,” Voss explains.“There's an exchange of information and an exchange of perspectives that is very important.”
For the academic side,Voss says,the ASEE program also “brings institutions of higher learning more insight into new technology.We give them an opportunity to work on real world problems and take it back to the classroom.”
译文：宇航员吉姆沃斯有着许多难忘的瞬间在他的职业生涯,其中包括3名航天飞行和一个太空行走.但他特别喜欢回忆决定性太阳系（为地球引力所束缚的）的经验,1980年夏天,他参加了美国航天局ASEE夏季学院奖学金计划.沃斯,然后一位理科教师在西点军校,被分配到的马歇尔航天飞行中心的推进实验室在阿拉巴马州,分析为什么液压油泵密封在航天飞机上的工作如此出色时,没有以前的印章.这是一个看似微小的问题之间的巨大复杂性,运行的航天计划.然而,重要的是美国航天局,因为任何裂纹的印章可能导致破坏性的结果,宇航员谁依赖于他们.
“我有点与美国航天局的工程师说,”象“ ,但我做到了主要由分析.我用一个手持计算器,没有一台电脑,做热力学（热力学的）的分析.“结束时的夏天,他像其他美国宇航局ASEE研究员马歇尔工作,总结他的调查结果在正式专题介绍和详细的文件.这是一个宝贵的时刻沃斯因为ASEE计划让他了解美国航天局说,加深他希望台飞行在太空中,并加强了申请宇航员地位.
这是不是一个容易的过程.沃斯实际上越过当他第一次用于宇航员计划于1978年.在今后9年来,他重新反复,并终于在1987年接受.自那以后,他参加了三次太空飞行任务.50岁的陆军军官,谁住在休斯顿,现已培训了4个月任务的机组成员在国际空间站上开始于2000年7月.
沃斯说,ASEE计划是美好的所有有关各方.“它使人们从学术的世界,使美国航天局的一个特殊财产为特定的时间内.它带来了一些新鲜的眼睛和新鲜的想法,美国航天局,并建立了联系与我们的高校,“沃斯说.“这里存在一个交流信息和交换观点,是非常重要的.”
学术方面,沃斯说,ASEE计划还“带来了高等教育机构更深入地了解新技术.我们给他们一个机会,工作的现实世界的问题,是否可以回到课堂.“

第一个空填 to fly
语法：the+序数词+人+to do,固定短语,“第XXX个做某事”的人；
第二个空填 incorrectly,修饰谓语wrote.如果要填incorrect,则要说wrote the incorrect answers或者the wrong answers.
请尽快采纳.只有采纳本题,才继续解答下一题.
