问题描述：
the little girl with her classmates ______ playing computer games happily now.为什么填IS,
答
填is ,with her classmates 为介词短语，
答
主语是单数…………
答
因为the little girl是主语，be动词用is，如果不用with用and那就是are了
答
如果有with看前面，前面是单数就用is，如果是复数就用are
答
主语有with的就远原则，所以主语是girl，用单数
答
with her classmates 是插入语。插入语最典型的就是这种用with的，以后记住就好
答
主语是the little girl
后面是with her classmates 介词短语
祝你学习进步
答
因为这句话的主语是“the little girl”,而“with her classmates”在这里是作为一个伴随状语.这句话也可以这样说：“The little girl is playing computer games happily with her classmates now.“
答
主语是the little girl第三人称单数，with her classmates作主语补足语
