as well,as well as,such as和also的区别？

Question

如题所述

Answer 1

回答：1. as well= too= also)，“也”的意思。它们均用在肯定句和疑问句中，as well 和too通常置于句尾，而also通常置于句中。如：
He works hard as well / too.
He also works hard.
2. as well as…：① 除了……之外，以及，不但……而且，既……又……。它是并列连词词组，连接两个相等成分，其强调重点不是后者，而是前者。如：
He is a writer as well as a teacher.他不仅是老师，而且还是作家。
② 和……一样好。它用于比较。如：
She sings as well as her mother. 她唱得跟她母亲一样好。
③ such as 可以用来列举事物，意思是：例如；such as 中的as（关系代词）可以引导定语从句，such是先行词。如：
He has been to many countries, such China, France, Canada and so on.他去过许多国家，例如中国、法国、加拿大等。
Such as you asked have been solved.你问的这些已经解决了。

Answer 2

意思上只有such as和其他三个不一样，它的意是比如，其他三个是也
其次，是放在句子的位置不一样，as well一般放在句尾，as well as 一般放在名词前面，such as 放哪都可以，also不能放句尾。
