为什么自考官方不把答案发出来呢?第5题
这道题我没法蒙,押个宝 D,但不知考哪方面的知识点
You should discuss your idea with your classmates becuase just ___ it to someone else helps you sort it our for yourself.
A have to explain B having to explain C have explained D having explained
答
You should discuss your idea with your classmates because just ____ it to someone else helps you sort it out for yourself.
A.have to explain B.having to explain C.have explained D.having explained
答：分析：because后这个从句缺少主语.能作主语的非谓语动词选项只有BD两个动名词.having to do sth.表示“不得不做某事”,好象是自愿的,不是老师逼你做的.having done sth.表示做过了某事之后,选这个比较靠谱.
翻译一下：你应该将你的想法和同学们讨论一下,因为刚刚跟某个人讨论过后有助于你自已将它分类整理出来.
