When should I write to them?Do you think?(when)

问题描述:

When should I write to them?Do you think?(when)
为什么是这样改:When do you think I should write to them?
而不是:Do you think when I should write to them?

do you think 是插入语.插到句子中间.整个句子是用when提问.回答时用一个时间来回答.如果变成Do you think when I should write to them?整个句子是一般疑问句.用Yes或no来回答.
