可汗学院经常会出一些新SAT备考的练习题提供给同学们去备考，这些题目跟正式的考试题目很相似。下面我们就一起来看一下语法部分前十道的可汗学院。希望对你们提供了一些参考!
1、The filibuster on voting-rights legislation went on for three days and ×nights; therefore, it meant that senators would sleep when possible.
原句没错，两句完整，罩子没有问题。而下面的选项，it的出现使得主语混乱。
2、they had less work to do than
×their work was the least among
原句繁琐。下面的选项前后主语不一致，而正确选项避免了以上两个问题。
3、In Germany, foresters discovered that trees killed by acid rain had begun to die four years earlier, even though the trees had shown no signs of disease then.
×earlier without any signs of disease shown then
原句没错，even though是状从罩没有问题。而下面的错误是由于主语不一致加上无缘无故的被动。
4、In the wild, pygmy chimpanzees are found only in an inaccessible region south of the Zaire River, since such is the case, very few are in captivity.
and so no more than a few are in captivity
× and very few are in captivity because of that
原句因为没有罩子所以错了。而错误选择是由于可以变成so的形式，不需要and… because of that. 正确答案中and so是一个罩子。
5、one of which is
×and one is
原句因为没有罩子错。错误选择中one指代不清。正确答案中看似没有罩，其实one of which就是定从罩which的变体。
6、Enzymes, among the oldest known chemical compounds, ACTually are nonliving protein molecules.
原句错误是因为上下句没有逻辑关系不应该用as。
7、The author takes the reader on a chronological journey through her native land, skillfully
×The reader is taken on a chronological journey through the author’s native land by skillfully
原句错误是因为插入句之后还是从句，就没有了谓语。错误选项是因为主语是reader，后面skillfully combining就不是作者而是reader了。正确选项助于统一，谓语正确。
8、Television’to become even more severe as a result of lobbying by special-interest groups. already made acuter by rising costs, threaten
×already made acute by rising costs, threaten
原句错误因为谓语用了单数但主语是复数。正确词组是made acute。
9、The information age has ushered children into a global society, a situation causing educators to lament
×which is the cause of educators lamenting
原句因为没有罩子而错。错误答案因为the cause of后面应该是句子。正确答案是一个很完美的定语从句省略，原句是(which is) a situation (that is) causing educators to lament
10、As one result of its new contrACT, the fire department can no longer offer overtime pay on weekends.
×One result of the fire department’s new contrACT is that they can no longer offer overtime pay on weekends.
原句和错误选择都是因为主语是单数却用了they。正确答案很完美。
