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.
