Question

She usually has (an egg, a glass of milk and bread )for breakfast. 对括号内的部分提问

问句应该是 what does she usually have for breakfast? 为什么要用what does ？ 能用what would吗？ what would 怎么用？

Answer 1

She
has
sth
for
breakfast.
这里的has是吃的意思，所以，跟其它行为动词一样，只能用does。
如：
He
has
lunch
at
about
12:30.
否定就是
He
doesn't
have
lunch
at
about
12:30.
如果“have"
是”有”，那么，概可用have,也可用do
如：
He
has
some
money.
He
hasn't
any
money.
Has
he
any
money?
He
doesn't
have
any
money.
Does
he
have
any
money.
如果句中有助动词，就用那个助动词进行疑问、否定的改变；
如果句中没有助动词，就用do,
does（一般现在时）did（一般过去时）来进行疑问、否定的改变。
这里是不能用what
would的。因为原句中没有would
What
would
you
like
to
have
for
breakfast?
你早餐想吃什么？
