SAT语法改进子题如何对比选项?.

　　在SAT语法改进句子题目中，因为大部分答案选项都没有绝对的错误，所以通过对比选项就成为了做这类题目的常见方法。那么在SAT语法改进句子题目中，该如何对比选项呢?下面通过两个例题，和大家介绍一下相关信息。

　　1、有时比较完了选项后，很难从已给信息中找出答案，这时我们可以比较剩下的选项，由选项中的不同来寻找答案。

　　例：In the eighteenth century, politics was thought to be an improper sphere for women, whose boycott of English goods was different than any protest the English had seen bore.

　　(A) whose boycott of English goods was different than any protest the English had seen bore

　　(B) whose boycotting English goods was different than any protest the English had seen bore

　　(C) whose boycott of English goods was different from any protest the English had seen bore

　　(D) whose boycott of English goods was different from any protest the English saw bore

　　(E) whose boycotting of English goods was different from any protest the English have seen bore

　　我们知道固定搭配应该是be different from, 而不是be different than , 所以马上把A和B排除掉。

　　下一步就应该来对比剩下的三个选项，C和D用了名词boycott，而E选项用了动名词boycotting，在SAT语法当中有一条非常重要的原则，即名词要优先于动名词，比方说同时出现了名词和动名词，就应该优先备选名词的选项。所以E错。

　　再把C和D进行比较，C用了过去完成时，D用了过去时，由题意应该是发生在18世纪以前，所以应该用过去完成时，所以答案选C.

　　2、找一个最佳的选项成为答案。

　　在解题的最后有时候可能会发现五个选项都不是非常完美，那么这时你就应该选择相对来说错误最少最为轻微的选项成为答案。

　　例：In exploring the rich variety of African artworks. The reason why one will note that certain patterns of meaning and usage occur again and again is nearly found in all world civilizations throughout most of history.

　　(A) In exploring the rich variety of African artworks. The reason why one will note that certain patterns of meaning and usage occur again and again is because this phenomenon of pattern repetition is nearly found in all world civilizations throughout most of history.

　　(B)In exploring the rich variety of African artworks. The reason why one will note that certain patterns of meaning and usage occur again and again is because this phenomenon is found in nearly all world civilizations throughout most of history.

　　(C)When you explore the rich variety of African artworks. The reason one will note that certain patterns of meaning and usage occur again and again is because this phenomenon of pattern repetition is found in nearly all world civilizations throughout most of history.

　　(D) When one explores the rich variety of African artworks. The reason one will note that certain patterns of meaning and usage occur again and again is because this phenomenon of pattern repetition is found in nearly all world civilizations throughout most of history.

　　(E) In exploring the rich variety of African artworks. The reason one will note that certain patterns of meaning and usage occur again and again is because found in nearly all world civilizations throughout history is this phenomenon of pattern repetition.

　　这道题目有些难度。这句话的意思是说在探索非洲艺术作品的富裕度时，人们将会注意到特殊模式的意思和习惯表达一再发生的原因是因为这种模式重复的现象能在几乎所有世界文明中找到。

　　当大家具备了一定的SAT语法基础后就可以看出来原文有两个错误。

　　首先严格意义上，英语语法中规定reason和because是不能够连用的，其次在划线部分里有一处表达不够正确，即this phenomenon of pattern repetition is nearly found in all world civilizations，它所表达的意思应该是这种模式重复的现象能在几乎所有世界文明中找到，但划线部分的意思变成了这种模式重复的现象几乎被找到了在所有世界文明中。所以nearly的放置位置不对。这样我们就可以纵向来寻找答案。看

　　完五个选项后大家可以发现没有一个选项改正了reason和because不能够连用的这个错误，所以这个错误只能放着。

　　再看其他选项，B, C, D, E把nearly的放置位置这个错误都给改正了，但是C和D引入了两个新的错误，即one和you 不能同时出现，在SAT语法当中这种情况是不允许发生的，所以C和D都错了。

　　再来对比B和E选项，我们可以发现E中用了被动，found in nearly all world civilizations throughout history is this phenomenon of pattern repetition，使得句子结构不够清楚明了，所以答案选B。

　　虽然说B还有reason和because不能够连用的这个错误，但它却是五个选项当中最佳的一个选项。因此我们讲是找五个选项中找一个最佳的选项成为答案，而不是找一个完全正确的选项。

　　以上就是对SAT语法改进句子题目的解答中该如何对比选项这个问题的一个详细的分析，通过下面的答案分析，大家可以看到一些窍门，只要能在实践中进行一些练习，相信大家很快就能掌握了。
