CORRECTIVENESS
I.Logical Fallacies (logical perfection is superior to grammatical imperfection, the first and foremost issue of GMAT grammar is logic)
(i)"Shanghai is bigger than any cities in China."is mistaken because Shanghai cannot be larger than any cities that inclusive of itself. So it should be"Shanghai is bigger than any other cities in China."
(ii)Blind eyesight; visible wavelength are logically flawed arrangement; it should be"blind people","visible radiation"instead.
(iii)Price cannot cause inflation but Price Increase can.
(iv)前后转折关系(by transitional words as‘but'etc.)是否成立要看前后的分类标
(v)准是否统一：big measurement→small measurement
III.主谓搭配和代词指代(七大类型)
(vi)出现句首名(vii)词+长串修饰考主谓搭配的可能性很大；
(viii)在英文中永远只有主谓搭配，同(ix)位语对谓语动词单复(x)数没有影响
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)倒装句(搞清主语在哪)
a.介词在句首，b.状语+句子谓语动词+主语(完全倒装)
c.极端形容词或So放在句首
(xii)Never, Whether, What, Should在一个完整句子做整个句子的主语，(xiii)谓语动作用单数
(xiv)代词指(xv)代，同(xvi)样一句话中相同(xvii)的代词指(xviii)代相同(xix)的事物：they, them, their在一句话中必须指(xx)代同(xxi)一主体
推论：It在句首做形式主语，后面it不能指代同一主体。如果出现这样的选项，一定错！
(xxii)Exoneration and his freedom例题：泛指(xxiii)和特指(xxiv)不(xxv)能对称；代词是个特指(xxvi)概念，(xxvii)不(xxviii)能随意丢失，(xxix)否则句子意思发生变化。
8GMAT中所有代词都不用来指代整个句子，只能是特定的名词或主体。但是当it在句首做形式主语时，可以指代：-
1.后面的不定式
2.后面的that从句，
3.如：It is you who is my friend that…
IV.固定搭配的错误
(xxx)require somebody to do something that +虚拟语气省略should of somebody that +虚拟语气省略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 [正确答案的出现方式] (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)事物比较)
