问题描述：
jane with his classmates ( ) going to play soccer this weekend
a.is b.be c.are d.does
答
A
这句话的主语是Jane，只有Jane哦。
答
选A
with his classmates 相当于补充成分不考虑在主语之内，主语是 Jane,单数，所以谓语动词用单数，
is going to
答
主句成分 Jane is going to play soccer this weekend.
with his classmates 是可以换位置的,可以放到后面,可有可无,
非主句成分的意思是去掉这部分,剩下的还能独立成句子.
