OG20 老问题了，一直没人回答！

OG 20An array of tax incentives has led to a boom in the construction of new office buildings; so abundant has capital been for commercial real estate that investors regularly scour the country for areas in which to build.

(A) so abundant has capital been for commercial real estate that

(B) capital has been so abundant for commercial real estate, so that

(C) the abundance of capital for commercial real estate has been such,

(D) such has the abundance of capital been for commercial real estate that（A）

(E) such has been an abundance of capital for commercial real estate,

Choice A is best. The construction so abundant has capital been... that correctly and clearly expresses the relationship between the abundance and the investors’ response. In choice B, the repetition of so is illogical and unidiomatic. Choices C, D, and E alter somewhat the intended meaning of the sentence; because of its position in these statements, such functions to mean “of a kind” rather than to intensify abundant.
        Choice D awkwardly separates has and been, og在这里的解释为不应该把 has 和been分开，但是答案a, 本身就把has & been 分开了呀，偶记得so开头应该是全倒装的，为什么答案a 只是部分倒装？, and the omission of that from C and E makes those choices ungrammatical

1，built 是及物动词，后面的宾语到底是什么，还是更本就不需要宾语？ 看到以前有牛牛说：scour the country for aresa in which to build=scour the country to build xx in area. 可是还是不明白宾语到底是什么呢？

2， 关于such 的倒装形式到底是全倒装还是部分倒装呢？

请哪个牛牛好心解答一下吧！

用形容词bundant可以形容capitala。所以在本题中用so比用such更简洁

AB候选。

A正确

B改变了原文中的倒装，语气改变了。错

PS:so that结构搭配部分倒装。你问为什么has&been分开了？

      是因为本分倒装需要助动词提前，has挪到主语前面。所以。。

so good a boy/so good has a boy been

such a good boy/such a good boy

既然用了such，原来充当表语的形容词，在such的形式中变成了定语，不存在谓语了

所以也不存在倒装的问题如果用such来表达，那么应该是such abundance has been...
