Researchers have announced that the magnetic fields emitted by one manufacturer’s security surveillance system, of which type there are 200,000 worldwide, can interfere with pacemakers and that this interaction can bring on missed or irregular heartbeats, nausea, breathlessness, dizziness, and even fainting.

A. of which type there are 200,000 worldwide, can interfere with pacemakers and that
B. of which, worldwide, there are 200,000 of that type, and which can interfere with pacemakers, and
C. of which type there are 200,000 worldwide, they can interfere with pacemakers and
D. 200,000 of which type exist worldwide, interfering with pacemakers, and

記得要畫線喔!

囉嗦一下!
k06922001建議您技巧固然好用,可是千萬不能依賴技巧,莫伯伯的名言:三分文法,七分句意,句意才是王道喔! ETS對there are的用法,認知為不夠簡潔, OG 11th No.1, 但是也有些題目的正確選項裏有there be的,要小心

這題考的是同位語,A.B.C.全都刪除
E existing 與 can interfere 不平行,不好

句意: 研究學家已經公佈,有一家製造商製造的安全監視器在全世界已經有20萬台存在,此監視器磁場的釋放會干擾pacemakers, 這磁場與pacemakers的互動會導致錯誤和不規律的心跳,嘔心,呼吸急促,頭暈,甚至會暈倒

我認為emitted 應該是主要動詞過去式,不是被動省略which was,
this interaction “can” bring on …用現在式解釋事實的發生,永久皆是如此

Opne to discuss~~

[stellaadixen]

我覺得答案應該是A啊! 有人覺得呢?

[hwatai]

應該是A吧?
Researchers have announced that the magnetic fields....只有A有接上magnetic fields 的動詞 ，完成完整的子句

爭議題

CD上有人google了一下（key words: the magnetic fields emitted security surveillance system)

http://www.google.com/search?hl=zh-CN&q ... %B4%A2&lr=

Michael Mclvor of the Heart Institute of St Petersburg, Florida, and colleagues announce in the New England Journal Medicine that the magnetic fields emitted by one type of shop security surveillance system, of which there are 200,...

A: of which there are 200,...是對的。

提供解題思路

[Zaitech]

答案應該是A吧....

BCDE的結構全錯啊....

Researchers have announced that the magnetic fields emitted by one manufacturer’s security surveillance system, of which type there are 200,000 worldwide, can interfere with pacemakers and that this interaction can bring on missed or irregular heartbeats, nausea, breathlessness, dizziness, and even fainting.

announce that S + V + ......

[aerobert]

答案應該是A吧....

BCDE的結構全錯啊....

Researchers have announced that the magnetic fields emitted by one manufacturer’s security surveillance system、of which type there are 200,000 worldwide、can interfere with pacemakers and that this interaction can bring on missed or irregular heartbeats、nausea、breathlessness、dizziness、and even fainting.

announce that S + V + ......

我的答案也是A，想法跟樓上的一樣

[willyyang]

我也是選 A

(B) worldwide位置不好，不知道修飾誰？ and which的用法也很詭異
(C) they指代不清楚
(D) researchers have announced that....這個that子句裡會找不到動詞
(E) 理由同 (D)

請NN指正。

[alva0930]

我也認為答案是(A)，如同Zaitech所說的，(D)的文法結構根本不對。
（ScoreTop上一堆老外的選擇也是壓倒性地選(A))

[chris8888]

這一題確實很不容易看出, 不過樓上說BCDE的結構全錯啊.... 是因為 S + V, 這一點不能夠認同

the magnetic fields emitted by one manufacturer’s security surveillance system, 200,000 of which type exist worldwide, interfering with pacemakers, and ...
=> exist 就已經是動詞了, 它沒有用exists 表示他不是which type的動詞, 而是200,000, 不能說他沒有主動詞.
=> the magnetic fields that interfere with pacemakers emitted by one manufacturer’s security surveillance system, 200,000 of this type system exist worldwide.
根據簡化字句的原則, 把that放到後面去用V-ing當形容詞子句, 意思也較清楚
至於A,
the magnetic fields emitted by one manufacturer’s security surveillance system, of which type there are 200,000 worldwide, can interfere with pacemakers and that
=> of which 就是 among the surveillance system type
=> the magnetic fields emitted by one manufacturer’s security surveillance system among the type there are 200,000 worldwide, can interfere with pacemakers and that
個人以為較不簡潔, 寫作上我個人也會寫A, 但是GMAT考試, 恐怕會選擇D, 我看過大陸網站說明, 他們認為D對. 寫作上和考試上確實還是有差距, 尤其是ETS的要求

[dibert8]

(D) interfereing 有修飾歧異的嫌疑.修飾 200,000 of which type 因為句意各自獨立,用 Ving 並不適當;修飾主要結構,找不到要修是哪個字才好.
以平衡的觀點,似乎只能選 (A) : ...anounced that... and that... (這時候,兩個 that 都不能省略.)
