Question

帮我做这个英语题，要解释下为什么的

Father asked Edison< >doing that for.
(a)how was he (b)what he was (c)why was he (d)where he was

Answer 1

Father asked Edison why he was doing that.和 Father asked Edison what he was doing that for。意思一样。what for = why 。 what 属疑问代词，可放在在介词后，充当句子成分，如宾语等。而why how where属疑问副词，后面引导一个完整句子。he was doing that for 不完整，应找一个可充当句子成分的，那就非what莫属了。

Answer 2

Father asked Edison< >doing that for.
(a)how was he (b)what he was (c)why was he (d)where he was

选b

what …for=why

是问原因的用法。

Answer 3

因为最后是FOR， 所以能接的就是WHAT了

没有FOR HOW, FOW WHY, FOR WHERE的说法

整句意思是：爸爸问EDISON那么做是为了(FOR)什么(WHAT)

Answer 4

c why was he

父亲问爱迪生他做那个干什么

如果是a,句子变成 ：father asked edison how was he doing that 怎么做的
b father asked edison what he was doing 刚赶在做什么
d father asked edison where he was. 地点

Answer 5

B 楼上的解释的很对!
