【—輔導(dǎo)之時(shí)間詞】關(guān)于時(shí)間詞的用法，老師做下面的講解學(xué)習(xí)。

　　時(shí)間詞用法

　　later / after / ago / before: 1later“…時(shí)間后”結(jié)構(gòu)：時(shí)間段+later

　　常用于一般過(guò)去時(shí)。They went to Beijing five days later.

　　(later前無(wú)時(shí)間段，單獨(dú)在句尾，常用于將來(lái)時(shí)：I’ll see you later.)

　　2after“…時(shí)間后”結(jié)構(gòu)：after+時(shí)間段，常用于一般過(guò)去時(shí)，和1相同。

　　They went to Beijing after five days. The dog died after a week.

　　(after也可加句子, 但主句不一定用一般過(guò)去時(shí)：I’ll send you an e-mail after I get home.

　　Return it to me after you finish it. 見(jiàn)2.)

　　3ago“…時(shí)間前”結(jié)構(gòu)：時(shí)間段+ago, 用于一般過(guò)去時(shí)。

　　The Greens moved to Shanghai four weeks ago. I saw it ten minutes ago.

　　(若有since+時(shí)間段+ago，常用現(xiàn)在完成時(shí)：Mr. Li has worked here since 5 years ago.)

　　4before 單獨(dú)放在句尾，常用現(xiàn)在完成時(shí)：“以前”

　　I have been to London before. He has seen the film before.

　　(若是時(shí)間段+before,常用過(guò)去完成時(shí)，“…前”： I had seen the film two weeks before. We had found out the answer to the problem an hour before.)

　　通過(guò)上面對(duì)時(shí)間詞用法的講解學(xué)習(xí)，相信同學(xué)們能很好的掌握了此語(yǔ)法的用法，希望同學(xué)們?cè)诳荚囍腥〉脙?yōu)異的成績(jī)。
