already可以用在疑问句中吗

Already用法

1. 表示“已经”,通常用于肯定句,不用于否定句或疑问句(此时要用yet )。如:

He has already started. 他已经动身了。

Has he started yet?他动身了吗?

He hasn’t yet started. / He hasn’t started yet. 他还没有动身。

2. 有时也用于疑问句,但往往含有问话人希望得到一个肯定回答或含有惊讶之意。如:

Has she gone to bed already?她不是已经上床了吗?

Is he back already 他怎么已回来了?

3. 一般说来,already 不用于否定句,但它有时可用于否定的条件状语从句中。如:

If he hasn’t seen the film already, he may get the ticket.

假若他还未看过这电影,他呆以弄到票的。

4. 与already 连用的时态:

(1) 与行为动词的完成体连用。如:

He has read the book already. 他已读过这本书。

By this time tomorrow I’ll have finished the job already.

到明天这个时候,我将已做完这工作。

(2) 与行为动词的进行体连用。如:

He is already working. 这已经在工作了。

When I came in, he was already laying the table.

我进来时,他已在摆桌子了。

(3) 与持续性动词或状态动词的一般现在时或一般过去时连用。如:

It’s already late. 已经迟了。

He already knew about it. 那时他已知道此事了。
