Grammar Fcus
用法：1.表示过去发生或已经完成的某一动作对现在造 成的影响或结果。e.g. –Have yu had yur lunch yet? –Yes, I have. I’ve just had it. (现在我不饿了。)
2. 表示动作或状态从过去某一时刻开始，一直 延续到现在，而且可能还要继续下去。e.g. I haven’t seen her these days. I’ve knwn Bb fr three years. I’ve been at this schl fr ver tw years.
时间状语：already, yet, just, ever, never, befre
构成： 现在完成时是由“助动词have / has+ 动词的过 去分词”构成的，规则动词的过去分词构成与 过去式相同，不规则动词的过去分词则需逐个 记忆。动词的过去式的变化和过去分词的变化 并不完全相同。我们对它们作了一个大致的分 类。
一、过去式和过去分词的变化相同规则变化：1. 一般在动词词尾直接加ed。如： pick → picked → picked; wish → wished → wished; stay → stayed → stayed2. 以不发音的e结尾的动词后面加d。如： like → liked → liked; hpe → hped → hped; phne → phned → phned
3. 以“辅音字母 + y”结尾的动词，变y为i， 再加-ed。如： study → studied → studied; hurry → hurried → hurried; reply → replied → replied4. 词尾只有一个辅音字母的重读闭音节动 词，要双写辅音字母，再加-ed。如： stp → stpped → stpped; clap → clapped → clapped
不规则变化：5. 以不变应万变。如： let → let → let; put → put → put; read → read → read6. 若中间有双写e，则去掉一个e，单词末尾再加t。如： feel → felt → felt; keep → kept → kept; sleep → slept → slept
7. 末尾的字母d变t。如： lend → lent → lent; build → built → built; send → sent → sent8. 变为以-ught或-aught结尾。如： buy → bught → bught; bring → brught → brught; catch → caught → caught; teach → taught → taught
句式1. 肯定句：主语 + have / has + 过去分词 (+其他)2. 否定句：主语 + have / has + nt + 过去分词(+其他)3. 一般疑问句：have/ has + 主语 + 过去分词(+其他)4. 特殊疑问句： 特殊疑问词 (不是句子主语) + have / has + 主语+过去分词 (+其他)2) 特殊疑问词(是句子主语)+have / has+ 过去分词(+其他)
already 意为“已经”，常用于肯定句中。一般置于助动词have/has之后，过去分词之前，但也可放在句末。e.g. 我已经看过这部电影了。 I have already seen the film. 我已经解决了这个问题。 I have already slved this prblem. 我已经做完家庭作业了。 I have finished my hmewrk already.
现在完成时--与already连用
yet，在现在完成时句型中常置于句末。 1) “已经”，常用在疑问句中。e.g. 琳达已看过这本书了吗? Has Linda read the bk yet? 你完成家庭作业了吗？ Have yu finished yur hmewrk yet? 2) “还，仍然”，常用于否定句和疑问句。e.g. 他还未开始工作。 He has nt begun t wrk yet.
现在完成时--与yet连用
just 意为“刚刚”，常用于肯定句中。一般置于助动词have/has之后，过去分词之前。e.g. 我刚吃过午饭。 I have just finished lunch. 我们刚刚听说她的婚讯。 We have just heard f her marriage.
现在完成时--与just连用
同学们要注意现在完成时与一般过去时的区别。虽然这两个时态都和过去发生的事情有关，但是现在完成时强调这一动作与现在的关系，如对现在产生的结果、影响等，而一般过去时只表示过去的事实，不表示和现在的关系。如：
I went hme at 10:00 yesterday. I have gt hme nw.我昨天十点回家的。现在我已经到家了。I have already finished my hmewrk. 我已经写完家庭作业了。 I finished my hmewrk an hur ag.我一个小时之前写完了家庭作业。
