展开Unit 8 Have you read Treasure Island yetSection A Grammar Focus-4cObjectivesTo learn the present perfect tense with “already” and “yet”.To learn some new words: fiction, technology, French…Grammar Focus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 you had your 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。现在完成时e.g. I haven’t seen her these days. I’ve known Bob for three years. I’ve been at this school for over two years. 时间状语:already, yet, just, ever, never, before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; hope → hoped → hoped; phone → phoned → phoned3. 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: stop → stopped → stopped; 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 → slept7. 末尾的字母d变t。如: lend → lent → lent; build → built → built; send → sent → sent8. 变为以-ought或-aught结尾。如: buy → bought → bought; bring → brought → brought; 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 + not + 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 solved this problem. 我已经做完家庭作业了。 I have finished my homework 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 book yet? 你完成家庭作业了吗? Have you finished your homework 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 not begun to work 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 of 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 home at 10:00 yesterday. I have got home now.我昨天十点回家的。现在我已经到家了。I have already finished my homework. 我已经写完家庭作业了。 I finished my homework an hour ago.我一个小时之前写完了家庭作业。活学活用1.
