改错原文

Applications outside the Earth' s atmosphere are clearly a good fit for robots. It is dangerous for humans to get to space, to be in space and to return from space. Keeping robots operating reliably in space presents some unique challenges to engineers.(1)____ The ultra-high vacuum in space prevents the use from moat types of lubricants.(2)____ The temperatures can swing wildly depending on whether the robot is in the sun light or shade. But, of course. there is almost no gravity.(3)____ This is actually more of an opportunity than a challenge and leads to the possibility of some unique designs. The conceptual robot has 21 independent joints. On earth it would be possible for this robot to support its own weight, but in space. the design presents some unique capabilities.(4)____ The robot can reach around obstacles and through out port holes.(5)____ The robot also possesses a huge degree of fault tolerance. It can continue to operate with excellent dexterity even after several joints fail.
NASA decided to develop a $288-million Blight Telerobotics Servicer (FTS) in 1987 to help astronauts assemble the Space Station, which was growing bigger and complex with each redesign.(6)____ Shown here is the winning robot design by May Marietta who received a $297-million contract in May 1989 to develop a vehicle by 1993. About the best thing which can be said for the FTS project was that it generated a lot of lessons leamed.(7)____ The robot never never and never will because it was never completed.(8)____ This project demonstrated that fault tolerance gone wildly will doom a robot.(9)____ The robot had so many redundant systems that there was just so much to go wrong.(10)____

答案解析

文章大意
本文讨论的是太空机器人。人类进入太空与返回太空的整个过程都充满危险，所以地球以外的工作可能只有依赖机器人了。但妥让机器人在太空中稳定地工作则给工程师提出了很多挑战。然而，挑战与机遇并存。一些独一无二的设计就是为适应太空工作的要求而产生的。
答案洋解
1．to→for词汇错误。“给某人提出挑战”用present challenges for sb．的句式，故介词应该用for。
2．from→of词汇错谩。原文虽有prevent一词，但并不是prevent ab. from doing sth.的固定搭配，句子含义为“阻止了大多不同种类润滑剂的使用”，从意思上可判断use和moat types of lubricants之间是从属关系，应用of。
3．But→And/Besides语篇错误。上文都是在讲太空状况对机器人设计者提出的挑战，本题所在句子是在上文基础上的延伸。“在太空中，几乎是没有重力的。
”富外之意，因为处于失重状态，设计时必须考虑到在地球上和在太空上的区别。所以本题所在句子是一种递进关系，而不是转折关系。
4．possible→impossible语篇错误。下文用but转折，说“设计呈现一些独特的能力”，反过来可以推断此处是说“机器人没有能力在地球上支持自身重量”。
possible不符合语义逻辑．应改成impossible才对。
5．out→out词汇错误。此处表示“机器人能绕过障碍物，穿越舷窗”，“穿越舷窗”包括进和出，而out只表示“出”，属于用词多余，故删。
6．∧complex→more语法错误。与complex并列的bigger已经用了比较级形式。
complex也应该用形容词比较级形式，周其为多音节单词，在其前面加more即可。
7．wich→that语法错误。当先行词前宥形容词最高级修饰时，定语从句必须用that引导，不能用which。
8．will→fly语法错误。never will fly中的fly不能省略，一旦省略，则表示与and之前的flew为同一词，然而不存在never will flew的用法，will后只能跟动词原形，所以fly必须朴上。
9．wildly→wild语法错误。gone是系动词，其后应该接形容词，故wildly应该改成wild。此处gone wild作后置定语，修饰fault tolerance。
10．so→too词汇错误。由so many redundant systems面知此处应该是说不容易出错，用too... to结构表示“太……以致不能……”，如应该改成too
