1) 连词前面的结构包括谓语动词,则连词后面平列结构也应该含有谓语动词
2) either…or…结构一定要平行
3) 用to do结构表达目的更加有效
(A) Broccoli thrives…and propagated by seeds…结构中and前后连接不对称,后者谓语结构不完成，
被动语态应为be done；either sown… or in…结构不平行,应该改为either sown… or sown in…或者
sown either in…or in…
(B) propagated by谓语结构不完整，缺少被动语态中的be; sown either directly in…or sown in…结构
不平行; designed so as to produce结构笨拙复杂,应该改为designed to produce
(C) either sown directly in the field or in plant…结构不平行; designed so that they produce结构复杂,
且they没有指代
(D) 正确, is propagated by seeds结构跟Broccoli thrives in结构构成并列; sown either directly in the
field or in…结构平行; designed to produce结构表示目的,简洁,有效
(E) sown either directly in the field or sown in结构不平行; for producing表示目的不如to produce表示
目的有效
句子结构: Broccoli thrives…and is propagated by seeds, either directly in… or in… to produce…
补充说明:
在某些情况下,并列结构的第二个成分的谓语动词可以省略:两个句子并列,第一个句子含有be动词或 者become,第二个句子中的be动词或者become必须省略,同时,一些重复的名词或形容词也必须省略. 例: Once the economic and social usefulness of the motor was demonstrated and its superiority to
the horse proved, ... (proved 前省略了 was)
73. (28457-!-item-!-188;#058&003634) (A) the human mind is not a "blank slate," but instead that it comprises specialized mental
mechanisms that were developed as a way of solving (B) the human mind is not a "blank slate" but instead comprises specialized mental mechanisms that were developed to solve (C) the human mind, instead of a "blank slate," it comprises specialized mental mechanisms that have been developed to solve (D) rather than it being a "blank slate," the human mind comprises specialized mental mechanisms that have been developed as a way of solving
(E) rather than the human mind's being a "blank slate," that it comprises specialized mental mechanisms that were developed as a way of solving
考点:简洁有效（Rhetorical Construction） 平行对称（Parallelism）
1) 连词前面的结构包括谓语动词,则连词后面平列结构也应该含有谓语动词
1）not …but…连接平行结构。
2）不定式表目的简洁有效。
(A) the human mind is not a "blank slate," but instead that结构不平行; developed as a way of
solving表达复杂,直接改为developed to solve表达目的
(B) 正确, the human mind is not a "blank slate" but instead comprises…结构平行; 用developed to
solve表达目的,简洁
