I.主謂搭配和代詞指代(七大類型)
(vi)出現句首名(vii)詞+長串修飾考主謂搭配的可能性很大;
(viii)在英文中永遠只有主謂搭配，同(ix)位語對謂語動詞單復(x)數沒有影響
Five hundred students each have a computer.
Each of five hundred students have a computer.
Leaf and *** material， the most *** parts， Vt.s
Five hundred students， groups each have a computer.
(xi)倒裝句(搞清主語在哪)
a、介詞在句首
b、狀語+句子謂語動詞+主語(完全倒裝)
c、極端形容詞或So放在句首
(xii)Never， Whether， What， Should在一個完整句子做整個句子的主語，(xiii)謂語動作用單數。
(xiv)代詞指(xv)代，同(xvi)樣一句話中相同(xvii)的代詞指(xviii)代相同(xix)的事物：they， them， their在一句話中必須指(xx)代同(xxi)主體。推論：It在句首做形式主語，后面it不能指代同一主體。如果出現這樣的選項，一定錯!
(xxii)Exoneration and his freedom例題：泛指(xxiii)和特指(xxiv)不(xxv)能對稱;代詞是個特指(xxvi)概念，(xxvii)不(xxviii)能隨意丟失，(xxix)否則句子意思發生變化。
8GMAT中所有代詞都不用來指代整個句子，只能是特定的名詞或主體。但是當it在句首做形式主語時，可以指代：
1、后面的不定式
2、后面的that從句
3、如：It is you who is my friend that……
II.固定搭配的錯誤
(xxx)require somebody to do something that +虛擬語氣省略should of somebody that +虛擬語氣省略should (xxxi)as的固定搭配begin as， depict as， regard as， perceive as， represent as， see as， be prizeless as， be acclaimed as， think of as， be seem as (xxxii)to be： consider something (省略to be) something [正確答案的出現方式] (xxxiii)help
a)help somebody to do something
b)help (to do) something
c)helpful in doing
(xxxiv)at point; at pole; at equator; aim at doing something
(xxxv)forbid somebody to do something; forbid something
(xxxvi)prohibit somebody from doing something; prohibit something
(xxxvii)compare A to B (把A比作B)
(xxxviii)compare A with B (相同(xxxix)事物比較)
(xl)in that標(xli)準書面英語，(xlii)漢譯為“原因體現在”
(xliii)more ancient標(xliv)準書面英語
