GWD-17-32
Navigators have known for thousands of years that the ocean has variable currents, but it is only in the last half century that a reasonably clear picture has emerged of the patterns and causes of ocean currents.

A. a reasonably clear picture has emerged of the patterns and causes of ocean currents
B. a reasonably clear picture of the patterns of ocean currents and their causes have emerged
C. a reasonably clear picture emerged of ocean currents, their patterns and the causes of them
D. there have emerged a reasonably clear picture of the patterns of ocean currents and what caused them
E. there had emerged a reasonably clear picture of the patterns of ocean currents and their causes



ans: A
====
A是怎麼平衡那個and的?
看不太懂... (?) and (causes of ocean currents)

[wanderlust]

你忘記劃線了

and平衡patterns和causes
介係詞of 後面接的受詞 ocean currents相同
所以提公因式 就不用寫兩次啦

[ariesmilla]

A. a reasonably clear picture has emerged of the patterns and causes of ocean currents
那個 of 是picture of 還是跟著emerge of...??

[peche]

in B, their can refer to "patterns" or "ocean currents"
but according to 句意 it should be :
patterns of ocean currents and causes of ocean currents


想請未依下 emerged 在gmat裡有沒有要注意的用法?

[jasperlin]

請教
動詞後加 of (emerged of)的用法, 慣用嗎

謝謝

個人意見
A選項的原句應該是a reasonably clear picture of the patterns and causes of ocean currents has emerged
因s-v距離過遠 所以將has emerged提前
變成a reasonably clear picture has emerged of....

[Belief]

這個可以用後位修飾處理

的確主詞動詞相隔太遠
所以把整個形容詞(of + N)放置後面

厲害

以前看NORTON ANTHOLOGY也有看過
不過老實說當初也是看不懂...

[jinoliway]

敢問Belief也是外文系前輩

變成a reasonably clear picture has emerged of....

如前輩所說的 把A還原
那為何用單數的動詞呢?
has emerged是修飾誰?

想是這樣吧!也避免頭重腳輕.

[willyyang]

has emerged 是動詞，不修飾誰。

主詞是 a reasonably clear picture of the patterns and causes of ocean currents

其實這一題，我是用代名詞(them)和所有格(their) 把錯誤答案排除的

[DoDoPrac]

(B) a reasonablt clear picture of... have emerged 主動詞不一致, have應該改為has
(C) 原句時態has emerged(和in the last half century連用)改變時態為emerged, 且原句還原a resonably clear picture of ocean currents改變句意, 變為海流的狀況
(D)(E) There have emerged不簡潔, 且there +完成式錯

(A)很好
picture has emerged of the (patterns and causes) of ocean currents

Navigators have known for thousands of years that the ocean has variable currents, but it is only in the last half century that a reasonably clear picture has emerged of the patterns and causes of ocean currents.

A. a reasonably clear picture has emerged of the patterns and causes of ocean currents
B. a reasonably clear picture of the patterns of ocean currents and their causes have emerged

支持B:
1.兩樣東西emerge, picture & causes 所以動詞複數.
2.their就近指代ocean currents .

A中 picture of causes 不合理啊.
