各位老师,下面这个句子是用to force 还是forcing?为什么?The government plans to bring in new laws _____ (force) parents to take more responsibility for the education of their children.
On Saturday afternoon the phone rang. I was still in bed , and had to force myself to roll over, pick it up and mutter hello. 这个句子为什么and前面加了逗号,并且pick和mutter用的是原型,请问这是什么用法?
