also，either，too与as well的区别
先来看几个例句
You study English and I also study it.你学英语，我也学.
You don't study English and I don't study it either.你不学英语，我也不学.
记忆：①also，表示“也”，通常用于肯定句，位于句中。
②either，表示“也”，通常只用于否定句，且要放在句末。
再来看几个例句：
He likes travelling and I liked travelling，too. 他喜欢旅游，我也喜欢旅游。
She is a teacher and a singer as well．她是教师，也是歌唱家。
记忆①too是个常用词，多用于口语，语气较随便。一般用在肯定句中，放在句末，用逗号隔开。
②as well 常用于口语，用法和 too一样，通常位于句末，它前面通常不用逗号。
