already的用法
2008-05-08 17:51
?1. 一般用于肯定句,不用于否定句或疑問(wèn)句 (此時(shí)用 yet),不過(guò)有時(shí)在疑問(wèn)句中也用它,那主要是用來(lái)表示驚訝 (且多用于句末)。如:Is heback already? 他怎么就回來(lái)了? Has she gone to bed already?她就上床睡了? Has she gone to bed already?2. 通常放在行為動(dòng)詞之前,特殊動(dòng)詞之后,有時(shí)為了表示驚訝的語(yǔ)氣通常放在句末。注意:一般不能直接放在時(shí)間副詞之前。如:9點(diǎn)鐘我已離開(kāi)了家。正:I had already left home at nine o’clock. 正:Already at nine o’clock I had left home. 正:3. 不要認(rèn)為 already只用于現(xiàn)在完成時(shí),其實(shí)除現(xiàn)在完成時(shí)外,它還可用于動(dòng)作動(dòng)詞的進(jìn)行時(shí)以及狀態(tài)動(dòng)詞的一般現(xiàn)在時(shí)或一般過(guò)去時(shí)等。如:When I came in, he was already laying the table. 我進(jìn)來(lái)時(shí),他已在擺桌子了。It’s already late. 已經(jīng)很遲了。
He already knew about it.
那時(shí)他已知道此事了。
