as well as是就近原则还是就远原则

　　as well as连接两个并列成分做主语时，其谓语动词的选择应该和as well as前面的主语也就是离谓语动词更远的主语保持一致，即就远原则。

 
　　1、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。
I not only play the guitar，I sing as well（＝I also sing ）.
我不但弹吉他，而且还演唱。
　　2、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：
You may as well go.
你去也好。
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。
　　3、as well 可以直接用于just后，用作应答语（可视为It's just as well、的省略），作“幸亏，幸而；无妨；没关系”解。如：
—We were too late to see the film.
我们去得太晚了，没有看上电影。
—Just as well、I hear it isn't very good.
不必遗憾，我听说电影也不怎么样。
