20. An 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 (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, and the omission of that from C and E makes those choices ungrammatical.
"such functions to mean "of a kind" rather than to intensify abundant."
1.首先一点要明确, such 是形容词, 修饰名词或名词性的结构(such a good job, such good work, such a good person,...), 而so 是副词, 修饰形容词 ( a so good job, so good work, a so good person...)
2. 其次, so that..., so...that 是固定结构; 而such that 应该没有这样的固定结构, such... that 是可能有的. He is such a good person that he can not refuse this request.
两点补充: 1. "such functions to mean "of a kind" rather than to intensify abundant." - 这样说是很有根据的. 因为such加强的是后面的名词, 重点是事物上. 而so加的强是后面的形容词. 这里的需要语感去体会.
2. 我个人在改错题中的一个发现是, 如果选项中有到装句, 要特别留意. "so abundant has capital been for commercial real estate that", 就是. 到装句成为正确答案的可能性非常大. , (大家去验证一下, 有例外的请发贴). 原因可能是因为到装句是英语中一种固定的结构, 它可以突出,强调重点, 使表达更清晰, 和GMAT对句子的要求一致. 而到装句结构和一般的句子不一样, 容易被人看成是错句!
