1、用法不同
as well常用作状语，作“又；也”解，相当于too或also，常位于句末，无须用逗号与句子分开。
如： I am going to London and my sister is going as well（＝going，too）.
我要到伦敦去，我妹妹也要去。
as well as常用来连接两个并列的成分，作“也，还”解。它强调的是前一项，后一项只是顺便提及。因此连接并列主语时，谓语动词与前一项一致；而用not only ...but also...连接时，谓语动词与后一项一致。
2、意思不完全相同
as well as 用来表示同级比较，指“一样好”。如：
You look as well as you did ten years ago.
你的身体看起来还和十年前一样好。
as well 在口语中也可用于句中，作“也好，也行”或“倒不如”解，用来缓和语气。如：
The weather was so bad that we might（just）as well have stayed at home.
天气太坏了，早知道如此，倒不如呆在家里为好。

as well 有两个意思：
1、表示“也，还，而且”等意思。相当于大家说的too，一般放句尾。
例如：He knows English as well. 他也懂英文。
2.、表示“正好；不妨；还不如”的意思。 相当于“just as well“。
例如：
（1）May as well give up. 不妨放弃
（2）You might as well leave.你最好还是走吧。
as well as 则是表示“除...之外（也）”的意思，表示人或事物除有之前说到的特征之外还有其他特点。还有一层意思就是“与...程度一样”，相当于and的并列关系。
例如：

他除散步之外还喜欢钓鱼和打猎。

2、在英国英语中，also通常不置于句末。too则多用于非正式的口语，且通常置于句末：
‘I’m going home now.’ ‘I’ll come too.’
“现在我要回家了。”“我也一起走。”
3、在肯定句中要增加一个否定成分可用not ... as well：
