第二阶段第26天

第26天 副词（四）
[学习要点]
搞清同义时间副词的区别，正确表达句子的意思。
[家教点窍]
一、ago, before
“若干时间＋ago”指离现在的若干时间以前，即“过去”。“若干时间＋before”指距
过去某时的若干时间以前，即“过去的过去”。只说“以前”不可用“ago”，只可用“before”。
二、in，after
“in+若干时间”指在一段时间之内或离现在的若干时间之后。“after+若干时间”指将
来某时之后。in与ago相反，after与before相反。
三、just,just now
两个都可表示“刚才”，但just常用完成时态，而just now 常用一般过去时。
四、still,yet,already
still表示动作继续进行，yet表示动作有待进行，already则表示动作已完成。
[典型例题]
例1 选择括号中的适当的词填空。
Tom told his mother that he saw a dog three days .(ago, before)
评析 三天以前应从汤姆说话时算起因为主句的动词“told”是过去式，所以“看见”
发生在过去的过去。答案选before。
例2 选择填空。
Can you finish the work ten days。
(A)after (B)before (C)in (D)on
评析 after表示的时间段应在将来某一特定时间之后，如after National Day, after
Mondays。before与句子的时态不符合，另外before所表示的时间段也应在过去某一特定时
间之前，如before three o’clock。on不能用在此。在题中，in可表示在十天之后，也可表示
在十天之内。答案选（C）。
例3 改错。
Why are you already watching TV? You should go over your lessons because you’ll
(A) (B)
have an examination tomorrow.
(C) (D)
评析 根据上句情景，意为主语仍在看电视表示不满。already表示已看完电视，意思
与句中情景不一致，语法上也有错误，所以应把already改成still，才能在句义和结构上都
和原句保持一致。
