how much are these books cost 是个什么啊? 进来看看,是一个选择题.上次提了一次,但又有一个问题

恩..首先先说下how much are these books cost是错的,应该是how much do these books cost,而且此句直接就可以作问题,不是倒装句.
而……how much these books cost.才是对的，因为这两个题都是宾语从句，后面疑问句要用陈述语气

I wonder__D__
A.how much cost these books
B how much do these books cost
C how much are these books cost
D how much these books cost
how much are these books cost 这是一个倒装句

how many people there are 不是倒装句,

Have you investigated ____ in scientific locations?
A.are there many people
B how many people are there
C how many people there are
D.that there are how many people
这题是选C，对啊。从句必须是陈述句语序。
解答满意吧。

你问的问题都不是倒装句的问题，题目也不是考察这个

它属于疑问句形式的句子，放在陈述句中，或者在其他句子中充当某一成分

应该用的是陈述句语序，而不是疑问句语序。

如：do you know how many books there are on the desk?
i don't understand why they have to do this。
could you tell me what you have bought yesterday?
...
...
...

第一道题的答案是D.因为这是一宾语从句，语序要用陈述语序
