可以.
it is how long that i dont know he has stayed here第二個問題你和我想的一樣，但是答案給的：I don't know how long it is that he has stayed here .不過還是 多謝你肯回答在這里強調(diào)句的形式是how + 形容詞+ it is 因此答案是I don't know how long it is that he has stayed here .不過我覺得其實都得可以的...how + 形容詞+ it is這個不是感嘆句嗎，感嘆句也算強調(diào)句？這是對強調(diào)句中特殊疑問詞考法.在這種題目中要注意詞序,即特殊疑問詞要置于句首或在賓語從句中居首,而且這里不是單獨出現(xiàn)how + 形容詞+ it is,在這里how后面跟從句作為賓語成分,是how引導(dǎo)的賓語從句..不是感嘆句..
