I had one after my lunch. 我是在饭后喝的。 one 在词句中代替了 a cup of coffee. 1. 谓语动词的形式是 过去式 had 2. after my lunch （午饭之后）是一个表示过去 的时间 所以，这是一个一般过去时的句子，而不是现在 完成时。
• 清理散乱的东西 • clear up the mess

现在完成时的用法
1) 表示到现在为止已经完成或刚刚完成的动作。
Now we have planted all the trees.
He has just come back.

2) 表示过去发生的动作,强调结果或对现在的影响。 Someone has broken the window. (窗户现在是坏的) I have already lost the key. (我现在没有钥匙) I haven’t read that book yet . (不了解书的内容) I have just cleaned my hands. (手是干净的)
1. I’ve already had lunch.
我已经吃过饭了。 2. I had lunch at half past twelve. 我在12点半吃的。 第一句话是现在完成时，现在完 成时表示过去发生的事情对现在 的影响，包含着“画外音”（我 不用再吃饭了）。
第二句话是一般过去时。如果仅 仅是表达在过去的什么时间做了 某事，特别是有具体的过去时间 状语的情况下，则用一般过去时。
Sam:
Aren’t you lucky!
Tom:
When are you going to have a holiday, Sam?
I don’t know. I’ve already had my holiday this year. Carol: Where did you go? Sam: I stayed at home!
Sam:
现在完成时
have/ has +过去分词
现在完成时
past now 一般过去时
future
一般过去时表示的是纯 粹在过去发生的事情。
现在完成时表示的是在 过去某个时间开始并持续 到现在的动作/状态,或者发 生在过去却对现在造成的 影响。现在完成时在汉语
中常用“了”、“过”或 “已经”来表示。
现在完成时 Present perfect 句型
.肯定句
“主语 + have（has）＋过去分词”。 注意：该句式中的have或has是助动词，has用于第三人称单数， 其它人称一律用have。
.否定句
主语+ “haven't（hasn't）＋过去分词”。
.疑问句
have（has) + 主语 + 过去分词 （ 回答：Yes，…have（has）． No，…haven’t（hasn’t）．）
一般情况下，动词的过去分词和过去式相同，如
leave----left----left 动词原形 过去式 过去分词
还有一些不相同的，则须日常积累，如 come----came----come 动词原形 过去式 过去分词
回顾 Lesson 79: have got 其实就是一个现在完成时，表示已经取得 或者有了。如： We haven’t got much tea or coffee. 这句话中的基本结构是： have + not + got
Lesson 83
Going on holiday

Review
• • • • • • • He's upstairs. He's having a bath. I'm nearly ready. Have a cigarette. Have a glass of whisky then. We went to a restaurant. What's the matter?
Excuse the mess.
屋子很乱，请原谅。
房间里乱七八糟。
This room’s very untidy.
room’s = room is
untidy = un- + tidy
un- 是否定前缀，形容词前面加 un- 之后，该形容 词的意思变成原形容词的反义词，如 tidy (干净)变 成untidy（不干净）。这样的结构还有： unhappy = un- + happy
have在完成时中，是助动词，无实在意义 have还可做实义动词 吃早饭 have breakfast
抽根烟 have a cigarette 洗个澡 have a bath
喝杯橙汁 have a glass of orange juice
现在完成时的基本结构：
否定
have\ has + (not) + done (过去分词)
I’ve just had a cup, thank you.
我刚喝了一杯，谢谢。 just 表示“刚刚”，也是完成时的标志之 一。 这句话中，完成时的基本结构是： have + just + had 这句话的“画外音”是“我不用再喝了，谢 谢。”
Let’s go into the living room, Sam. 我们到客厅里去吧！
