1、ETS的辩证法学习得挺好,并在语法上体现得淋漓尽致。所以不要指望用某个通则或公理就来解决问题。一定要具体问题具体分析。(所以从这个意义上说公理是有百害而无一益啊)

好比说ETS喜欢平行结构,对应的它必然给你来一个形式上不平行的正确选项(太多了,举不胜举)。最恶毒的是这个:

396. In recent years cattle breeders have increasingly used crossbreeding, in part that their steers should acquire certain characteristics and partly because crossbreeding is said to provide hybrid vigor.

(A)in part that their steers should acquire certain characteristics

(B)in part for the acquisition of certain characteristics in their steers

(C)partly because of their steers acquiring certain characteristics

(D)partly because certain characteristics should be acquired by their steers (E)

(E)partly to acquire certain characteristics in their steers

另外:

require of sb to do sth

一会儿是对的,一会儿是错的。

cost of…to

也是一会儿是对的,一会儿是错的。

比较的助动词一会儿省略,一会儿不省。

考试时,这根弦一定要绷紧啊!要掌握ETS改错的精髓,并灵活运用。
