Because Miranda, the smallest moon of Uranus, has a large number of different surface features, including craters, mountains, valleys, and fractures, some astronomers suggest that at one time repeated impacts broke the surface apart, and after which the fragments were subsequently rejoined becaust of mutual gravitational attraction.
A. repeated impacts broke the surface apart, and after which the fragments were subsequently rejoined becaust of
B.repeated impacts on the surface broke it apart, after which the fragments having rejoined with
C.through repeated impacts that the surface broke apart, after which the fragments subsequently rejoined by.
D.the surface broke apart with repeated impacts, after which the fragments having rejoined through.
E.the surface broke apart as a result of repeated impacts , after which the fragments rejoined through.
A. and作連詞已經可以連接句子,and連接的兩個句子屬於同一層次;又出現after
which再次扮演連 詞的成分,連接的句子屬於子句,與主句構成主從關係。因此,該選項句子結構混亂;
prep解释里是这样说的
有两个问题
(1) after不也可以当介词吗?
(2) 这里的which是指代什么?
看句义感觉是前面句子the surface broke apart
虽然每个选项都有which
可是which不能指代句子不是GMAT的天理吗?
还是另外有所指呢?
which指repeated impacts
after可當介詞與連詞
谢谢~~~
那prep用这个(after为连词)当作删去答案的依据
是不是不太恰当啊
需要看題目而定,大部分SC的題目主要考點都只有一個或兩個~而且很明顯,但就這題來說
我個人覺得考點比較小
A錯在多了一個連詞
B,C,D,E考兩個點,第一個是用through比with或by更為準確,表示rejoin是透過相互引力達到而不是被相互引力達到
第二個點比較不容易看出,是兩個斷句間的邏輯關係,前面一句應該先說明surface經過...而broke,然後後一句
是說在repeated impact之後又重新rejoin.有點考分詞構句修飾的味道
你說的
A錯在多一個連詞
是指
and 跟 after嗎?
那如果把after看作介詞不就沒有這個問題了嗎?
不好意思~~~
還是有點不了解
另外,能不能也幫我看看這題~~~ 謝謝~~~

我看過了~另一題主要適用for來解題,因為for在該題中會造成ambiguity
例如:
the judge ban a law for preventing surf
到底是指法官禁止一個防止衝浪的法令呢?還是法官為了不給衝浪而禁止一個法令?
D跟E則是以時態判斷,D較好的原因是that enables....表示一個事實,指那個trick
的用處,用will比較不好,這是我個人用語感判斷。
after在這邊一定是當連詞的,因為介詞後面不能接子句,所以and + after造成redundancy.
希望對你有幫助.大家互相切磋
不好意思
我還是有一點點不了解
如果把after which當作介詞片語
作為時間副詞不可以嗎?
對不起啊 腦袋還轉不過來
另外那一題,我的問題是紅色的字部分
(不知道你是不是沒看到)
那一題
能不能移駕到那邊討論呢 呵~~~
先謝謝你了~~~
找到答案了,对于which的解释应该这个才是合理的:
如果which指代impact,会造成语法上surface broke apart这个动作与fragment rejioned这个动作前后关系不清楚,而逻辑上应该是fragment rejioned在surface broke apart之后。。或许有点没表达清楚...
