Lesson 88 Have you … yet
1. 现在完成时的用法
(1) 表示动作发生在过去某个不确定的时间，但对现在留下了某种影响和结果。常被just、already、yet 等副词修饰。如：
　　-Have you had lunch yet
　　-Yes, I have. I‘ve just had it.
　　你（已经）吃午饭了吗？
我刚刚吃过。（现在我不饿了）
(2) 表示从过去某一时刻开始一直持续到现在的动作或状态。这个动作可能刚停止, 可能仍然在进行。常带有for和since等表示一段时间的状语。　
He has taught here since 1981.
　　　　他自1981年就在这儿教书。　　　　
I haven't seen her for four years.
　　　　我有四年没见到她了。
(3) 表示说话前发生过一次或多次的动作, 现在成为一种经验，一般译为汉语“过”，常带有twice , ever, never, three times 等时间状语。
I have been to Beijing twice.
我去过北京两次。
2. 现在完成时的构成
现在完成时是由助动词 have (has)+动词的过去分词构成。助动词说明该谓语是属于现在时范围。它和主语的人称、数要保持一致。过去分词是主要的谓语动词，说明句子的意义。
肯定句式：主语+have (has)+done
否定句式： 主语+have (has)+not + done
一般疑问句：Have (Has)+主语+ done ？
特殊疑问句：特疑词+ have (has)+主语+ done ？
3.现在完成时的时间状语
(1) 现在完成时属于现在时范围，故不能和过去的时间状语连用。如：yesterday, last Sunday,in1990, three years ago等。
(2) 现在完成时可以和带有since或for等表示“一段时间”的状语连用,表示动作或状态从某一时刻开始，一直持续到现在。
eg：I haven‘t seen him for two years.　
但是，像come,arrive,buy等终止性动词不能与表示“一段时间”的状语连用。要用，必须改为“be（在）”等延续性动词来表述。
4.非延续性动词到延续性动词的转换
arrive→be here　　　　　　　 begin(start)→be on
　　　 die　→be dead　　　　　　　 come back→be back
　　　 leave →be away　　　　　　　 fall ill(sick,asleep)→be
get up→be up join →be in或 be a member of… 　　　 　　　　　　　　
open　 →be open go out →be out
　　 finish →be over　　　　　　　 put on　→wear 或be on
　　　 close　 →be closed　　　　　 go to school→be a student
　　　 borrow　 →keep　　　　　　　buy　 →have　　　　　
　　　 catch(a cold)→ have(a cold)　 get to know →know
　　　 begin to study→study　　　　　come to work→work等
时态 用法 动词形式 时间状语标志词 例句
