Father asked Edison< >doing that for.
(a)how was he (b)what he was (c)why was he (d)where he was
(a)how was he (b)what he was (c)why was he (d)where he was
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。
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
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)
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。
B 楼上的解释的很对!
