too,also,either这三个词都有“也”的意思,但是用法不一样。
(1)too是普通用语,多见于口语中,常用于肯定句和疑问句的句末,too前的逗号可有可无;too也可以用于插入语,置于句中,其前后都用逗号隔开。
例句:I like apples, too.(我也喜欢吃苹果)
My teacher, too, is in the classroom.=My teacher is in the classroom, too.(我的老师也在教室里)
Did Tom finish his lunch, too?(Tom也吃完午饭了吗?)
(2)also常用于正式文体,一般用于句中,位于助动词之后,实意动词之前。
例句:Her father is also a scientist.(她的父亲也是一位科学家)
My brother also plays soccer very well.(我弟弟足球踢得也很好)
Do you also like swimming?(你也喜欢游泳吗?)
(3)either当“也”的意思时,只能用于否定句。
例句:I don’t like bananas, either.(我也不喜欢吃香蕉)
She didn’t go to school, either.(她也没去上学)
Amy doesn’t have any idea, me either.(Amy 没有任何主意,我也没有)
