http://forum.chasedream.com/dispbbs.asp?BoardID=23&replyID=3480531&id=392110&skin=0 似乎是A

据说已经得到语法区某位斑斑的确认

                 GWD27-Q18:

The Near Earth Asteroid Rendezvous (NEAR) spacecraft will orbit the asteroid Eros for a year, slowly moving closer to the surface of the object to make ever more precise measurements that scientists hope will enable them to understand how the solar system formed some four billion years ago.

A.    to make ever more precise measurements that scientists hope will enable them to

                                                                        that scientists hope will...        关于them的指代问题,本

                                                                       是由that引导的同位语         题复数名词有二,

                                                                       从句,hope不是谓动,后         measurements以及scientists,

                                                                       面所接不是宾语从句           而同位语引导词that指代的是

                                                                      所以不加that                           measurements,measurements不能

                                                                                                                       enable他自己做什么事且measurements

                                                                                                                       也不能发出understand的动作,

 所以A中的them只能是scientists                

                                                   

B.    to make ever more and more precise measurements, which scientists are hoping to enable them

这个选项直接改变了时态,而且也没有道理,排除        

C.    for making ever more precise measurements, and scientists hope that they will be able to

   and是并列平行结构的标志词,要求前后尽量一致,本 

选项就算for doing没有错,那也应该是NEAR will orbit,

and scientists will be able to ...至于hope可以用插入语

的形式加入,比如hopefully                                                  

D.    with the purpose of making more precise measurements than ever, and which scientists hope will enable them to

       with the purpose of 不简洁                                                            and后边是which从句,不是完整句子

E.     in order to make more precise measurements than it ever did, and scientists are hoping they will be able to

                                                                         it指代不清,是NEAR还是Eros,后边是时态问题和B一样

我觉得B

xiaolishally

这个到底选什么啊？

mm007_mmgmat

选C！

叉二

这道题是TN24中第18套的18题，TN24答案是A

我也觉得A好些

herminliu

不知道正确答案是什么，不过我也觉得是B

因为A.more precise没有than来完成这个比较

C.不对，因为这边是表示目的，但是GMAT不支持用for doing sth来表达目的的含义

E也不对，根据白勇语法中说的，表示目的用to do, for sth, so that结构，尽量不用in order to, in order that结构，因为语气太过强烈

D.的用法；with the purpose of 确实不简洁，此外and wich使得scientist....和之前的成了并列关系而不是因果关系，所以错误

至于B的are hoping to，是be doing sth的结构有将来时态的含义，区别于will do结构，表示这个行动有计划会发生

以上是我的观点不知道是否正确，请指教

习惯留念

TN答案是A。误导大家了。SORRY~

herminliu

我还没有开始做GWD的题，但是我想知道，他的答案是否正确，是否有每题的分析？

that scientists hope
            

号称是插入语的~~~GWD基本上答案仅供参考~~~~如果有疑问就去语法区按照题号找讨论
