会计考友

知识要点：
       在英语的句子中，谓语动词的形式应与主语的人称和数保持一致。如何判定，则要看句子的意思。多数情况下，根据句子的主语形式就能判定，但有的则要看整句的意思，及强调的内容。下面我们就常用的、易混的几种情况作一下解释。
1、以单数名词或代词、不定式、动名词短语或从句作主语时，谓语动词要用单数形式。如：
1）The book is on the table.
2）He is reading English.
+ `$ W' I$ Y, T4 u7 Y, H" a6 f9 d. w3）To work hard is necessary.（It is necessary to work hard.）
4）How you get there is a problem.
2、复数主语跟复数动词。如：Children like to play toys.
3、在倒装句中，动词的数应和它后面的主语的数一致。如以here,there开头，be 动词与后面第一个名词一致。如：
1）There is a dog near the door.
( u8 j3 [. C/ r& B1 t2）There were no schools in this area before liberation.
5 m/ P" f* E3 M! q" w3）Here comes the bus.
4）On the wall were two famous paintings.
5）Here is Mr Brown and his children.
