海之灵01 共回答了17个问题
|采纳率100%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.1年前查看全部

- Gregory Olsen is not an astronaut. He is a 60-year-old busin
Gregory Olsen is not an astronaut. He is a 60-year-old businessman from New Jersey where he owned his successful technology company. This week, however, Olsen became the world’s third non-astronaut to pay for a trip into space.
On Monday, the Russian-built Soyuz rocket, carrying Olsen, an American astronaut and a Russian astronaut, docked (对接) at the International Space Station (ISS).
Olsen’s wish has come true. He is the third “space tourist” in four years to travel on a Russian craft to the space station. American Dennis Tito and South African Mark Shuttleworth have both made round trips to the ISS. Going into space is not easy, however. Olsen has worked hard for two years to prepare for it.
The Russian Federal Space Agency offers an ISS trip to anyone who can afford it and pass the necessary training. Olsen reportedly paid $20 million for his trip. The Russian space program has been short of money in recent years and is looking for individuals interested in space travel to _________.
NASA(美国宇航局)has relied on the Russian space program and its Soyuz capsule(太空舱)to transport American astronauts to the ISS since the Columbia space shuttle disaster in 2003. The space shuttle Discovery ( 发现号宇宙飞船)made a flight earlier this year, but the program stopped halfway because of safety concern. So far, the Russians have not charged the U.S. for trips to the ISS. That may change by the end of the year.
As one of the few space tourists, Olsen focuses his attention on the glory of traveling in space.
小题1:What is the best title of the passage? (Please answer within 5 words.)
________________________________________________________________________________
小题2:Which sentence in the passage can be replaced by the following one?
Up till now, Russia has been helping American astronauts go to the International Space Station for free.

小题3:Fill in the blank with the proper words or phrases. (Please answer within 10 words.)

小题4:According to the passage, who can travel into space in the Russian shuttle? (Please answer within 30 words.)

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。

|采纳率80.8%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?...1年前查看全部

英语翻译
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 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.”李晓军1年前1
