2.辨析 too，also与either 这几个词都表示“也”的意思。
（1）too多用于口语中，置于句末或句中，在句末时，通常其前有逗号，在句中时，前后都有逗号。Tom is a student，and Jack is a student，too.汤姆是学生，杰克也是学生。
I，too，have been to the Great Wall.我也去过长城。
（2）also通常置于实义动词之前，助动词、情态动词和be动词之后。He can speak English and he can also speak French.他会说英语，也会说法语。
（3)either用于否定句中，置于句末.My mother hasn’t been to Beijing. I haven’t been there，either.我妈妈没去过北京，我也没去过。
