Look,the teacher as well as all his students is playing games on the playground这里为什么用is不用ar
而为什么This is my twin sister Lucy.Both she and I are good at drawing.这里要用are?

as well as 连接两个并列主语,谓语同前面的主语保持一致.
还有比如 with,like,but,except,besides,includ-ing,together with,along with,as well as,more than,no less than,rather than 等,其谓语通常要与前面一个主语保持一致.
