---______that he managed to get the information?184839574---______that he managed to get the information?---Oh,a friend of his helped him.A.Where was it B.What was it C.How was it D.Why was it 如果此题选C的话,怎么将强调句还原呢?我认为该题的题干有错,应改为a friend of his helping him.这样才能还原成完整的句子.A friend of his helping him,he managed to get the

1)该对话应该是比较口语式的,所以语法就显的没那么按部就班啦.你可以理解为把Oh,who helped him其中的"who" 换成"a friend of his"就是啦."朋友帮助他"和"他得到信息"可以是2个独立的句子的.当然也可以是因果关系.
2)就此问题来说,不管怎么也只能选C.因为此选择题考的重点是how ,where what ,why使用的场景.不过楼主的钻牛角尖的精神还是值得我们学习滴.呵呵

c , ---Oh,a friend of his helped him.
这里没有错啊 ， 就 a friend of his 是表示的他的其中一个朋友 ， 是在句子中做主语 。

楼主你要看问题回答的是什么 这里他要说的是他怎样成功知道哪个信息的 重点在“怎样”后面的回答可以知道 这里应该能确定是how 还原应该是 It is a friend of his that helped him managed to get that information.
