最新现在完成时讲义及练习

Grammar语法:simple present tense 现在完成时

A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

I am doing my homework. I have done my homework.

B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。

I’ve known Alice for three years.

现在完成时的构成：

主语+have/has +动词的过去分词. I have done my homework.

1.否定：have, has后面加not . I have not done my homework.

2.一般疑问句：have, has提到主语前Have you done your homework? 区别：

has gone to:表示某人已去了某地，而没有回来(去了没回)

has been to :表示去过某地(去过已回来)

has been in/at(in表示相对大一些的地点;at表示相对小一些的地点): 表示一直呆在某地,常与时间段搭配.

since+时间点=for+时间段since+一般过去时态的时间状语从句=since+时间点+ago

现在完成时往往同表示不确定的过去时间状语连用

already(肯定句中)，yet(否定，疑问，句末)，just(刚刚), before(之前), recently(最近), still, lately, never等:

I have already finished my work.

I haven’t finished my work yet.(否定句)

Have you finished your work yet?(一般疑问句)

动词过去式和过去分词的变化相同

一般在动词词尾直接ed. 如：pick → picked → picked;

wish → wished → wished; stay → stayed → stayed

A-A-A: let → let → let; put → put → put; read → read → read, cut→cut→cut

A-B-B: lend → lent → lent; build → built → built; send → sent → sent buy → bought → bought; bring → brought → brought;

A-B-C: choose→chose→chosen do→did→done

see→saw→seen drink→drank→drunk

go→went→gone take→took→taken

A-B-A: run→ran→run come→came→come
