必修二Unit1 语法:主谓一致
知识点1 语法一致原则
语法一致原则是指主语和谓语在语法形式上必须一致,即谓语动词的单复数形式由主语的单复数形式决定。这一原则主要适用于以下几种情况:
1、不可数名词或可数名词单数形式作主语时,谓语动词用单数形式;可数名词的复数形式作主语时,谓语动词用复数形式。
例句:
(1)Every part is to be carefully checked before they are put together. 组装之前,每一个部件都要仔细检查。
(2)A big part of the corn is used to feed chickens,pigs and cattle in that country. 在那个国家,一大部分玉米被用来喂鸡、猪和牛。
(3)These toys are designed for children under three years old. 这些玩具是为三岁以下的儿童设计的。
2. 复合不定代词 anyone,anything,someone,somebody,something,everyone,everybody,everything,nobody,nothing 及不定代词either,each 等在句中作主语时,谓语动词用单数形式。
例句:
(1)Everyone is ready for the sports meeting. 每个人都为运动会做好准备了。
(2)Everything is in a complete mess,which drives people crazy. 所有的事情都乱成一团,让人发疯。
3. 单个的动词不定式(短语)、v-ing (短语)或主语从句作主语时,谓语动词一般用单数形式。
例句:
(1)Listening to music makes me relaxed after a busy day. 听音乐使我在一天的忙碌之后得到了放松。
(2)When they could finish the task is not known yet. 他们何时能完成这项任务还未知。
