语法题中窥视SAT写作高分句型

　　教SAT写作以来，总是会有学生问我在写作中使用什么样的句型会比较讨考官喜欢。针对这个问题，答案就在我们的SAT考题里。我们把语法部分的错误改正过来之后的句子就是考官所认可的句型，所以我会劝学生去仿写ISE或者IS部分的句型。现在取OG的几个IS题为例，和大家看一下考官所欣赏的句子是什么样子的。

　　The depths of the Arctic Ocean are hard to study, mainly because the icy surface is being difficult to penetrate using current techniques.

　　(A) to study, mainly because the icy surface is being

　　(B) to study as a result of the icy surface, mainly, is

　　(C) to study, mainly because the icy surface is

　　(D) studying, mainly from the icy surface being

　　(E) studying, mainly resulting from the icy surface being

　　这是OG407页IS部分第二题。正确答案是C。在这个题目中考官向我们传达这样的信息，表示原因使用because最简洁，如果使用其他的方式表示原因起码要做到语法正确。其次在这道题目中考官还像我们传递这样的信息，表达做到客观，中间这个单词mainly用的非常好，这是我们学生在写作中经常会忽视的。比如在Topic Sentence中学生经常会这样写：

　　Walt Whitman created the first genuine epic in American literary history--- Leaves of Grass, because he persisted his dream firmly.

　　如果在because前面加个mainly，度的把握上会更好。

　　A cure for some kinds of cancer, scientists believe, may be found within the next decade.

　　(A) scientists believe, may be

　　(B) scientists believe they may be

　　(C) being maybe, in the belief of some scientists,

　　(D) there are some scientist who believe it may be

　　(E) which, some scientists believe, may be

　　这是SATOG408页IS第8题。在这道题目中，正确答案是A。在这道题目中考官向我们传递了这样的信息，主语，+插入语+谓语动词是不错的句型。

　　因此上面的Topic sentence可以改成：

　　Walt Whitman, the father of free verse, created the first genuine epic in American literary history--- Leaves of Grass, mainly because he persisted his dream firmly.

　　希望同学们在做题的过程中仔细的思考，把在语法中遇到的题目不仅能做对而且还能在写作中使用出来。
