___is no doubt that he will passe the test .A:It B:ThereC:ThatD:This
我觉得应该是There吧,可是看到别人说是It,更有改错题答案是把There改成了It,到底是怎么一回事啊~好困惑啊!有It is no doubt that 的说法么,最好能分析一下,谢谢了~
There is no doubt that 毫无疑问固定句式呢？
还是主语从句呢~
完整的题是这样的~
A-It' s easy for Tim to go throuh the coming test.What about Jim?
B-____is no doubt that he will pass it ,too.
是需要结合语境么？
是啊~今天高二的英语考试题么！
