neither-either-both的练习题.doc

both与bothand的用法：1、both意思是两者都其中both接谓语动词要求用复数形式。如：Both answers are right.2、（1）Both与动词连用时，大多数放在系动词be之后，其它动词之前。如：His parents are both workers.They both enjoy reading.（2）若句中谓语动词包含情态动词或助动词时，both大多放在第一个情态动词或助动词之后。如：The bridges must both be built this year.两座桥都必须在今年修建。3、Both可与and构成并列连词，连接两个性质相同并在句中作相同成分的并行结构，意思“两者都”，其谓语动词用复数形式。如：Both he and his brother are good at English.(连接两个主语)She can both dance and sing.(连接两个谓语动词)Mary is both kind and beautiful.(连接两个表语)either与eitheror的用法1、either意思是两者中的任何一个, either接谓语动词一般用单数形式如：Either(of them)is OK. (他们两个中)任何一个都行。2、either.or.意为或者或者；不是就是，要么要么之意。表示两者之一，连接句子中两个并列的成分，其谓语动词应与最近的一个主语在人称和数上保持一致，这就是我们通常说的就近原则。例如： When the girl is happy, she either sings or dances. 那个女孩高兴时，不是唱就是跳。 Either you or I am going there tomorrow. 明天要么你去那里，要么我去那里。 注意：如果把上句变成一般疑问句，助动词形式与主语you保持一致，所以要用are提问，而不是am。例如： Are either you or I going there tomorrow? 明天是你还是我去那里？ Either you or he has lunch at school. 其一般疑问句应为：Do either you or he have lunch at school? 是你还是他在学校吃午饭？ neither与neithernor的用法1、neither意思是两者都不 ，接谓语动词一般用单数形式。如：Neither boy is going there. Neither of them likes football. 2、neither.nor.表示既不也不。其含义是否定的，可连接任意两个并列的成份，当neither.nor.连接两个主语时，也应遵循就近原则。Neither dad nor mum is at home today. Neither he nor I am well-educated.他和我都没受过良好的教育。 补充：1.not onlybut also意思“不仅而且”，谓语动词的数应与but also后主语的数保持一致（就近原则）Not only you but also Tom teaches in this college. Not only Mr. Tom but also you teach in this college. 练习题D 1、We asked John and Henry some easy questions, but _ of them could answer them.A. noneB. both C. allD. neitherC 2、Which is more useful, biology or chemistry?
