下面就是今天
1.抓住明显错误进行排除
首先大家需要寻找划线部分是否有明显的语法错误或逻辑错误，有的话马上排除，再纵向寻找答案，把选项中没有改正这些错误的都给排除掉。
例：The benefits of exercise is as psychological as physical.
(A) is as psychological as physical
(B) are more than psychological, they’re physical
(C) are as much psychological as physical
(D) have psychological aspects as well as the physical ones
(E) is psychological in parts and physical as well
我们可以看出这道题目的主语是benefits是复数，所以谓语动词也应该用复数，但这里谓语动词是单数，所以马上把A排除掉，纵向寻找答案，发现E没有改正错误，D选项错误的换了时态，所以都错了。比较B和C选项，B选项的意思不对而且显得比较多余累赘，所以答案选C.
2. 利用常考考点作为切入点
有时大家如果把一些常考考点给记住的话，就可以大大提高解题的速度。比如在SAT语法当中，划线部分经常出现的错误就是代词指代不清和限定性从句的引导词指代混乱。因此如果划线部分出现了这两类词的话，在未发现明显错误的时候，我们就应该以这两类词为切入点，通过确认其真实指代对象和语法指代对象是否一致来排除错误选项。
例：The automobile, popularized by Henry Ford, was invented around the same time as the Wright brothers developed the airplane, and it is an important method of transportation.
(A) The automobile, popularized by Henry Ford, was invented around the same time as the Wright brothers developed the airplane, and it
(B) The automobile, popularized by Henry Ford, was invented around the same time as the Wright brothers developed the airplane, and
(C) Invented around the same time were the automobile, popularized by Henry Ford and the airplane, which the Wright brothers developed, and it
(D) The automobile popularized by Henry Ford. Was inverted around the same time as the Wright brothers developed the airplane and this is why it
(E) An invention around the same time as the Wright brothers developed the airplane, the automobile, popularized by Henry Ford, it
我们一起来分析一下这道题目，题干说由HF所推广的汽车，与W兄弟所发明的飞机差不多在同一时间，它是一种重要的交通方法。大家发现划线部分的最后一个词it就犯了模棱两可的错误，它既可以指代汽车，又可以指代飞机，所以A错，同样C, D, E也都有it，所以也不对。答案应该选择B选项，把it给去掉了，这样就避免了指代不明的错误。
