Question

How long do you think it will be ___ the bus arrives here ? A. when B. before. C.since D.after

which one is correct and reason.

Answer 1

题目:How long do you think it will be ___ the bus arrives here ? A. when B. before. C.since D.after
答案是B。
句意:你认为巴士需要多长时间才能到达这儿?
理由:首先,句中“do you think”为插入语,在具体理解句意和做题时可省略；根据句意,该句强调的是巴士到达这儿前的那段时间,因此应用“before"。

不过,说实话,"when"的用法我不太清楚,见谅…

Answer 2

B. before

你认为公共汽车还需要多长时间才能到。

Answer 3

B How long do you think it will be before the bus arrives here ? 你认为车开到这将需要多久。*^_^*

Answer 4

B do you think 是个插入语，把他提取出来以后句子中的主谓就很清楚了。翻译成，你认为公交车还有多久到站？

Answer 5

选B，　你认为公交车还要多久才能到？
