教材知识全解 讲透知识 查漏补缺

知识点一 感叹句的用法

教材原文What a long time you slept in the forest! 你们在森林里睡了太长时间了！

本句是What引导的感叹句,感叹名词time. what引导的感叹句用来感叹名词.

What a nice day today!今天天气真好！

拓展 感叹句通常由what或how引导,表示惊讶、赞美、喜悦、愤怒等情感.结构如下:

What a beautiful girl she is!她是多么漂亮的女孩啊！

What important jobs they have done!他们做了多么重要的工作啊！

What good news it is!这是多好的消息啊！

How old a building that is!＝What an old building that is!那是多么古老的楼房啊！

How interesting the story is!这个故事多么有趣啊！

How time flies!时光飞逝！

例1 (2020贵州安顺中考)＂Pingtang Bridge has the highest concrete bridge tower in the world."

“________ amazing it is!"

解析 此处的amazing 为形容词,需要用How来引导感叹句

答案A

知识点二 be made of的用法

教材原文 It's leading us to that wonderful house made of bread, cake and candy.它在把我们引向那座由面包、蛋糕和糖果做成的奇妙的房子.

本句中的 made of bread, cake and candy 是过去分词短语作后置定语,修饰house.过去分词作定语表示被动关系.

be made of 是固定搭配,意为“由······制成”.

There is an ornament made of shells on the wall.墙上有一个由贝壳做成的装饰品.

The machine is made in Germany.这个机器产于德国.

The model plane is made by my elder brother.这个飞机模型是我哥哥制作的.

These grapes are made into wine.这些葡萄被制成了葡萄酒.

The chair is made of bamboo.这把椅子是由竹子制成的.

The paper is made from wood.纸是由木头制成的.

This machine is made up of three parts.这个机器由三部分组成.

例2 I'd like to have this salad; it is________ blueberries. Do you want to have a try?

解析 be made from表示“由······制成”,一般指看不出原材料,或发生的是化学变化;be made of也表“由······制成”,一般指能看出原材料,或发生的是物理变化;be made in 指的是生产于某地;be made into的意思为“被制成······”.这种沙拉是能看出原材料的,故B选项符合题意.

答案 B

知识点三 enough的用法

教材原文 Who is brave enough to eat my house?谁足够勇敢来吃我的房子?

本句中的brave enough表示“足够勇敢”.enough是副词,表示“足够”,修饰形容词或副词时,enough要后置.

The room is large enough to hold thirty people.这个房间足够大,可以容纳30人.

拓展 enough的词性和用法

We have enough time/time enough to read the reference books.我们有足够的时间阅读参考书.

She is old enough to travel by herself.她年纪够大,可以独自旅行了.

注意so...that...句型可以和含enough to的句子进行同义转换.

The car is so cheap that I can afford it.＝The car is cheap enough for me to afford.

这辆汽车如此便宜,我能买得起它.

例3 (2020广西北部湾经济区期末)In fact I didn't know him________. I only saw him three times.

解析 句意:事实上,我对他不是很了解.我只见过他三次而已.well是副词,enough修饰形容词或副词时要后置,即well enough,故答案选D

答案 D

重点难点全解 精讲精解 精准高效

Instead of 的用法

instead of 是介词短语,除含有“代替”之意以外,还含有否定概念“而不是”的意思,其后通常接名词、代词或动名词.

I'll have tea instead of coffee.我要茶,不要咖啡.

I stayed in bed all day instead of going to work.我在床上待了一整天,没有去上班.

例4(2020江西赣州石城期末)He will go there________ me. I'm too busy at home.

解析 句意:他将代替我去那儿.我在家里太忙了.instead of意为“代替”,后面常跟名词、代词或动名词;instead意为“代替”,作副词用,根据后面的me可知答案选

答案 B

单元语法全解 熟悉句型 把握要领

as soon as, unless 和 so...that引导的状语从句

本单元的语法重点仍然是状语从句,主要讲述了以下三种状语从句:

1.as soon as引导的时间状语从句

as soon as 表示“一······就·····”,引导时间状语从句.当主句是一般将来时的时候,从句要用一般现在时,可简单记忆为“主将从现”.

He will hand in his report as soon as he arrives.他一到达就会上交他的报告.

2.unless 引导的条件状语从句

unless是连词,意为“除非;如果不”,unless引导条件状语从句时,可与if...not进行同义转换.

I won't go to the party unless I'm invited.＝I won't go to the party if I'm not invited.

除非我被邀请,否则我不会去参加聚会.

拓展 if和unless引导条件状语从句时,也同样遵循“主将从现”的原则.主句是一般将来时或者含情态动词的句子,从句要用一般现在时.

You can ask me for help if you need help.如果你需要帮助,你可以向我求助.

We will go hiking if it doesn't rain tomorrow.＝We will go hiking unless it rains tomorrow.

如果明天不下雨,我们会去远足.

3.so...that引导的结果状语从旬

so...that...意思是“如此······以至于······”,其中的so是副词,常用来修饰形容词或副词,that后接从句.

She is so young that she can't look after herself.她太小了以至于不能照顾她自己.

The boy ran so fast that I couldn't catch him up.这个男孩跑得太快了,以至于我追不上他.易错易混全解
