        我是娜弟

        現(xiàn)在完成時(shí)的用法:

        我已經(jīng)當(dāng)老師3年了,可能還繼續(xù)當(dāng)下去。

        此用法涉及到時(shí)間段,因此關(guān)鍵時(shí)間狀語(yǔ): for+ 時(shí)間段; since +時(shí)間點(diǎn)(自從...以來(lái));these days, recently, so far 等等就會(huì)提示時(shí)態(tài)用完成時(shí)。

        因此咱們勾劃時(shí)間狀語(yǔ)和關(guān)鍵詞是很重要的。

        望采納!

(4)在由why,what,where,whoever,who,that,as 等引導(dǎo)的從句中,也常用一般現(xiàn)在時(shí)代替將來(lái)時(shí)。例如: 1)Free tickets will be given to whoever comes first. 2)You’ll probably be in the same train as I am tomorrow. 2.一般過(guò)去時(shí) (1)表示過(guò)去某一特定時(shí)間所發(fā)生的、可完成的動(dòng)作或狀態(tài),常與表示確切過(guò)去時(shí)間的詞、短語(yǔ)或從句連用。例如: We went to the pictures last night and saw a very interesting film.
