【—輔導之時間詞】關于時間詞的用法，老師做下面的講解學習。

　　時間詞用法

　　later / after / ago / before: 1later“…時間后”結構：時間段+later

　　常用于一般過去時。They went to Beijing five days later.

　　(later前無時間段，單獨在句尾，常用于將來時：I’ll see you later.)

　　2after“…時間后”結構：after+時間段，常用于一般過去時，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去時：I’ll send you an e-mail after I get home.

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

　　3ago“…時間前”結構：時間段+ago, 用于一般過去時。

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

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

　　4before 單獨放在句尾，常用現在完成時：“以前”

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

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