陈春辉：SAT语法突破之难题突破

　　SAT备考学员对于SAT语法的难题很头疼，总觉得难以突破，那么我们同新航道陈春辉老师来学习一下SAT语法的难题突破吧。

　　一般说来，容易出错的题要么是那些错误隐蔽的题，要么是涉及到平日考生不够熟悉的知识点的题目，这些题目考生会在做官方指南和真题册时碰到，平时应注意总结。我把难题的考法总结为以下几类：固定搭配，代词不划线，“潜规则”，独立主格结构，虚拟语气。下面举几个难题的例子：

　　1. Winston Churchill, unlike (A) many English prime ministers before him (B), had deep insight into (C) the workings of (D) the human mind. No error (E)

　　本题考生会选择C或者D，但是按照刚才讲过的原则，不要随便找短语搭配的错误以及复数名词一般没有错，这两个选项都排除了，应该选E。做完这个题后，考生应当总结固定搭配insight into,以及workings是运行原理的意思。

　　2. Although the candidate promised both to cut taxes and improve services, he failed to keep either of them after the election.

　　A. Although the candidate promised both to cut taxes and improve services, he

　　B. The candidate, having promised both to cut taxes and improve services,

　　C. Although the candidate made promises both to cut taxes and improve services, he

　　D. Having promised, first, to cut taxes and, second, to improve services, the candidate

　　E. The candidate’s promises were both to cut taxes and improve services, he

　　本题考点隐蔽，导致考生选择A(No error).但是读完这个题干以后，就会发现句末有一个keep either of them的表达，代词them没有划线，但是仍然摆脱不了嫌疑犯的罪名，其实这个them应该指代promises, 但是上文没有名词promises，所以应选择C。

　　3. Although he played a leading role in planning spacecraft expeditions, Dr. Carl Sagan refused to accept praise for the plans he designed nor otherwise profiting from later advancements in space exploration.

　　A. designed nor otherwise profiting

　　B. had designed nor otherwise did he profit

　　C. has designed nor otherwise to have profited

　　D. designed or otherwise profited

　　E. had designed or otherwise to profit

　　对于本题，首先应该掌握or otherwise这个搭配，另外结合课上讲的虚拟语气大三标志之一的otherwise识别出此题考察虚拟语气，而且是和过去事实不符，所以动词应该用had done，答案应该选择E。
