as well not only but also as well as too四者的区别是什么

题目

as well not only but also as well as too四者的区别是什么

答案

as well 与too 用法类似,都用在肯定句,并位于句末,too经常是和句子隔开,而as well 不必,例如 He likes chocalate as well./ He likes chocalate,too.
as well as 与not only...but also 意思差不多,都是不但,而且的意思,但主谓一致是需要注意,例如 I,as well as my parents,am going to visit my granny this weekend.（谓语和I 保持一致）
Not only he but also Tom are doctors.(谓语用复数)
