each是形容词、代词,可用作主语、宾语、定语等,意思是“每个”或者“各个”,表示单个概念.
1.each+单数名词+and(each)+单数名词时,
谓语动词用单数。
Each boy and each girl has got a seat.(每个男孩和女孩都有一个座位。)
2.如果each 作主语,则谓语动词用单数。
Each of them has an English dictionary.(他们每人都有一本字典。)
但请注意:
The childrean each have a new school bag.
Each of the children has a new school bag.
为什么会是这样呢?因为第一个句子each作的是
同位语,真正的主语是they所以谓语动词用复数,第二个句子的主语是each,根据上面提到的,所以谓语动词用单数。
