Lesson 19

1. 特殊难点

在口语或非正式文体中，我们可以使用缩略形式，但在正式文体中还是用非缩略形式为好。

I have not seen him for three years.

I haven’t seen him for three years.

我已经三年没有见到他了。

I am = I’m

He/she is = He/she’s

They are = They’re

She was = She wan’t

I have = I’ve

He has = He’s

I had not = I hadn’t

I do not = I don’t

He does not = He doesn't

She did not = She didn’t

I will = I’ll

I will not = I won’t

I can not = I can’t

You must not = You mustn’t

2. 单词辨析

Still & Yet

Still表示某情况在说活时仍然存在；它在句中的位置通常是在主动词和否定词的前面，系动词和情态动词的后面:

My finger still hurts. 我的手还在疼

A solution still hasn’t been found ( 或：A solution has still not been found )

还没找到办法。

It’s still wet outside. 外面还是湿的。

I can still remember. 我还能记得。

Yet 通常用在否定句中表示事情尚未发生；用在疑问句中则表示 “已经”；在句中它通常放在句尾或紧跟在否定词的后面（比较正式）：

I don’t know the answer yet. 我还不知道答案

The contract has not yet been signed. 合同还没签字。

“Have you seen that American film yet?” “Not yet.”

你看了那部美国电影了吗？还没有

* still, even 与yet 在修饰比较级时意思相同，但yet较为正式：

a yet worse mistake 一个更糟糕的错误

a still more difficult question 一个还要难的问题

even less lucky 还要不幸
