新一轮中考复习备考周期正式开始, (1)以单数名词或代词,动词不定式短语作主语时,谓语动词要用单数;主语为复数时,谓语用复数,例如: He goes to school early every morning. The children are playing outside. To work hard is necessary for a student. (2)由and或both……and连接的并列成分作主语时,谓语动词用复数。例如: Both he and I are right. Mr Black and Mrs Black have a son called Tom. 但并列主语如果指的是同一人,同一事物或同一概念,谓语动词用单数。例如: His teacher and friend is a beautiful girl. The poet and writer has come. (3)由and连接的并列单数主语之前如果分别由each,every修饰时,其谓语动词要用单数形式。例如: In our country every boy and every girl has the right to receive education. Each man and each woman is asked to help. (4)主语是单数时,尽管后面跟有but,except,besides,with等介词短语,谓语动词仍用单数。例如: The teacher with his students is going to visit the museum. Nobody but two boys was late for class. Bread and butter is a daily food in the west. (5)一些只有复数形式的名词,如people,police,cattle,clothes等作主语时,谓语动词要用复数。例如: A lot of people are dancing outside. The police are looking for lost boy. (6)由each,some,any,no,every构成的复合代词作主语时,谓语动词都用单数。例如: Is everybody ready? Somebody is using the phone. (7)有两部分构成的物体的名词,如glasses,shoes,trousers,chopsticks,scissors等作主语时,谓语动词用复数。例如: Where are my shoes?I can’t find them. Your trousers are dirty.You’d better change them. 如果这类名词前用了a pair of等,则往往用作单数,谓语动词的单复数形式往往取决于pair的单复数形式。例如: Here are some new pairs of shoes. My new pair of socks is on the bed. (责任编辑:admin) |
