OG 13 SC73 请问thereby的用法！

raylu1987

Unlike the original NationalMuseumof Science and Technology in Italy, where the models are encased in glass or operated only by staff members, the Virtual Leonardo Project, an online version of the museum, encourages visitors to "touch" each exhibit, which thereby activates the animated functions of the piece.
(A) exhibit, which thereby activates
(B) exhibit, in turn an activation of
(C) exhibit, and it will activate
(D) exhibit and thereby activate
(E) exhibit which, as a result, activates

OG答案是D，但是我印象中，thereby 不是有固定搭配是 thereby doing吗？
它在这直接跟动词原形是什么用法？是做therefore的意思？
而且原文中说，activate是和touch平行的，为什么touch是不定式，activate却可以省？或者说thereby在这里是做to的意思？

我覺得瞭解詞的用法，可以從詞性入手，然後類比。
thereby是副詞，表示“因此，由此，从而”。
therefore/thus也是副詞，跟它相同意思，用法可以類比。
副詞不可能有後面絕對要加doing的結構，這是詞性決定的。而且副詞一般是不能代替介詞/to使用的。
thereby doing，thereby是作為副詞修飾doing這個動作。
官題中，and後面加thereby，只是爲了突出前後的動作有因果關係。如果沒有了thereby，僅僅根據and前後成份獨立平行的關係，是判斷不出exhibit和activate二者有什麽關係、發生先後順序等。
to touch each exhibit and thereby activate
就是touch和activate平行，因為and後面直接用了activate。
如果後面是to activate的話，平行的就是to touch和to activate.

我觉得这里 and 中间省略了一个口语中会用到的"it" 英文正规书写里不能用it 来代替前一句话，所以就直接省略了，这个"it"是understood.
前一句话是描写个动作，而动作的结果activate    也可以理解成the acts of touch activate....

thereby 可以理解成 by the acts of touch therefore activating.....

谢谢！
但是OG中的解释是：Because to"touch"is an infinitive, the second verb form must be, as well, though the to may be implied.

也就是说，OG中也说了activiate是和to touch平行的，但是又说“though the to may be implied.” 虽然to被含蓄化了。。。这个是想能隐掉就能隐掉得吗。。。

然后OG中在正确答案后又有补充：The agent of the action is clearly indicated by the grammatical structure of the sentence; visitors areencouraged to "touch"... and thereby (to) activate.
我想知道它在thereby后面括号上to是什么意思呢？告诉我们此处本来要有to但是省略掉了？
谢谢啦~

它的意思是to可以保留，也可以去掉。對於句意的理解沒有問題。
to touch each exhibit and thereby activate
to touch each exhibit and thereby to activate
上面兩個句子，一個意思。lz可以參考下面的note來理解。

【Ron's note】
按照parallel marker的種類平行的分類：ONE-PART (such as "and", "or", "but")、TWO-PART (such as "not only ... but also", "both ... and").

lWhen you have PARALLELISM WITH A ONE-PART SIGNAL, the only words that are "locked in" are the ones directly FOLLOWING the signal. As long as you can find the corresponding structure in the other part, then the parallelism is fine.【對於one-part類型的parallel marker，比較的內容要與parallel marker後面lock住的內容一致】

examples:

i worked in nevada and florida.
i worked in nevada and in florida.
BOTH OF THESE ARE FINE. Reasons:
in the first, the part that's "locked in" by the signal and is just Florida. Therefore, the parallel construction would be just nevada. since that construction is there, the sentence is parallel:
i worked in
nevada
and
florida.

in the second, the part that's "locked in" by the signal and is in florida. therefore, the parallel construction would be just in nevada. Since that construction is there, the sentence is parallel:
i worked
in nevada
and
in florida.

如對於這部份內容還是比較模糊的話，建議看一下MANHATTAN SC 5TH...我記得裏面是有講過這個的

谢谢Terrace，看完Manhattan回过头来看你这个解释，好清楚！谢谢！

滴答哈哈

Mark一下！
