因为这几道题大概是同一个知识点 能总结一下更好~
1.Combine each pair of sentences into one sentence,___ the second as an attributive clause.
A.using B.use C.to use D.used
2.He was busy writing the story all the morning ,only ___ off occasionlly to have some tea.
A.breaking B.to break C.having broken D.to have broken
3.Mary is writing a letter to a friend of hers in her room,___ him to her birthday party.
A.having invited B.inviting C.invite D.invited
1.A
2.A
3.B
都考查的是动词ing形式做状语的情况.第一句,use 其逻辑主语是祈使句的主语(you),且其后带了宾语,必须用主动形式,而且与主句动作同时发生.另两句情况类似.
再问: 那个假设主语为人但是动作不是同时发生的话一般用原型么?
