SAT语法在整个SAT考试中是很重要的一部分，我们除了有很好的语法基础外，还要会分析语法成分，下面我们为大家整理了几个SAT语法练习题的详细解析，希望对大家的备考有所帮助。
1. For those who suffer（A） from seasonal allergies, remaining（B） indoors between the hours of 5:00 A.M. and 10:00 A.M. are（C） a good idea, since that is when pollen is usually emitted（D）。 No error（E）
答案：C
改法：are改为is
解析：句子主语是remaining,doing做主语当单数看。
2. During the male courtship ritual of the periodical cicada （Magicicada cassini）， a type of insect chiefly famous for its long hibernation, periods of synchronized singing alternate with periods of silence.
A.hibernation, periods of synchronized singing alternate
B.hibernation, they alternate periods of synchronized singing
C.hibernation that alternate periods of synchronized singing
D.hibernation, periods of synchronized singing alternating
E.hibernation alternate periods of synchronized singing
答案：A
解析：注意题中a type of insect chiefly famous for its long hibernation是the periodical cicada的同位语，所以hibernation之前都是状语，hibernation之后必须有主句。A是主句正确。B中代词they无指代。C中没有主句。D中alternating不能做谓语动词。E缺主语，如果有人把a type of insect当成句子主语的话，首先语义有问题，其次，谓语动词也应该用alternates而不是alternate,E错。

解析：not only…but also是固定搭配。
