This is the best book I have ever read.

It is the first time I have played the computer games.

在现在完成时中,一次性动词不能和一段时间状语连用

例：He has bought the book for 3 years。(错）

因buy这个一次性动词不能和一段时间for 3 years连用, 改正的办法有：

He has bought the book.. （去掉一段时间for 3 years)

He bought the book 3 years ago （改为一般过去时，使句子的意思不变）

It’s/It has been 3 years since he bought the book。 = 3 years has passed since

he bought the book。 （改为固定句型 It is/It has

been --—since--—）

He has had the book for 3 years. （用延续性动词have代替buy)

另外

①come/arrive/get to/reach → be here

I have come here for 3 years。（错） 改为:I have been here for 3 years.

②leave/go →be away

He has left for 3 hours.（错） 改为：He has been away for 3 hours。

③begin/start →be on

The film has begun for 3 minutes。（错） 改为：The film has been on for

九年级英语第十三单元重难点及单元练习

九年级英语第十三单元重难点及单元练习

⽯家庄市第20中学 鄢桂风

⼀、疑点难点破解

1. You have to be careful.你得⼩⼼。

疑点：be careful“⼩⼼，当⼼”

如：Be careful while crossing the road.过马路要⼩⼼。

难点：be careful后常跟of短语。与它同义的有look out。

如：Aren’t you a bit too careful of your health？你对个⼈的健康难道不是有点过于⼩⼼了吗？

Look out！There’s danger ahead.当⼼！前⾯有危险。

2. At times an ad can lead you to buy something you don’t need at all.有时⼴告可能导致你买你根本不需要的东西。

疑点：at times= sometime，是副词性短语，表⽰事物发⽣的频率。

如：He is late for school at times.他有时上学迟到。

难点：1)对含有at times的短语进⾏提问时，⽤How soon.

如：How soon does he go to school late？At times.

2)句中lead意为“使得、导致”，常⽤于短语lead sb. to do sth.“导致某⼈做某事”

如：What leads you to think so？

3.Soft lighting makes people look good，but it make food look bad.柔和的光线使⼈的脸⾊看上去很好看，但使⾷物看起来很难看。

疑点：look good/bad意思为“外表的颜⾊看起来好看/难看”

如：The traffic accident made him look bad.

难点：look fine/ well指看起来⾝体健康

如：You look better today than yesterday.你今天看上去⽐昨天好多了。
