新人教版高一英语必修一单元重点解析:Earthquakes

本单元对话引出地震这个话题。对话中提到了地震的时候的现象和人的感受。本单元的阅读课文是了解发生在San Francisco地区的严重地震场景和有关地震发生时的基本常识。同时在文章里有一些重要的语法知识,如定语从句的使用:A wide and busy road which was built like a bridge over another road fell onto the one below. etc.

重点知识讲解:

1.What does "quake" means , as in the word "earthquake"?

像" earthquake" 这个词中的quake是什么意思?

As in the word "earthquake" 是个省略结构,完整的说法为:as it does in the word "earthquake". as 在此为连词,表示“如“的意思。

It sounded like a train that was going under my house. 那声音听起来就像有一列火车在我的房子底下开过似的。

sound 为系动词,后接名词、介词短语做表语,意思是“听起来”。

Your idea sounds (like ) a good one.你的注意听起来不错。

What he said sounded like a fairy-tale.他所说的话听起来就像神话故事。

表示“听起来像什么”的时候,用sound like….。like 在此是介词表示“像”的意思。类似于sound的常用系动词还有:feel, taste, smell, look.

例如:

Cotton feels very soft. 棉花摸起来很柔软。

It looks like a beautiful picture. 那看上去就像一幅美丽的画。

2.I was in the kitchen cooking something and I felt the floor move. 我当时正在厨房里作饭,我觉得地板动了一下。

cooking something 在本句中为现在分词短语做伴随状语。

句中的move是省略了to 的不定式,做宾语补足语。动词feel的宾语补足语可以是动词原形,也可以是动词的ing形式或过去分词形式。

例如:

When I heard his words, I felt my heart beating faster.听了他的话,我感到心跳加快了。

He felt someone knock at the door. 他感到有人敲了一下门。

he boy felt his back patted by someone. 那个男孩子感到有人拍了他的脊背。

3.And then I watched all the glasses on the table fall off onto the floor. 后来我观察到桌子上所有玻璃杯子掉到了地板上。

辨析:fall off / fall down

fall off 表示“从。。。。上落下或掉下”。off为介词或副词。fall down的意思是“倒塌、掉下”,不强调落物的来处。

例如:

I saw him fall off his horse.我看到他从马上掉了下来。

Flowers fell off to the ground. 花儿凋谢了,落到了地上。

Autumn comes and leaves are falling off the trees. 秋天到了,落叶纷纷。

A stone fell down in the earthquake. 一块石头落了下来,砸中了他。

The old house fell down in the earthquake. 老房子在地震中倒塌了。

4.A great part of the city was destroyed and a large number of buildings were burnt.城市的大部分地区被摧毁,许许多多建筑物被火吞噬。

A number of 相当于many.意思为“许多”,后跟可数名词的复数形式。短语中的number前可以由large / small来修饰,构成a large / great / small number of 短语。

例如:

1)A number of people were killed in the traffic accident. 有许多人在那场车祸中丧生。

2)A large number of students went to see Mr. Zhang when he was ill.张老师生病的时候有许多的学生去看望他。

Only a small number of people are against this plan.只有少数人反对这个计划。

辨析:a number of / the number of

a number of 意思为“许多”。中心词为of后面的复数形式。

the number of 的意思为 “…的数量”,中心词为number,因此,“the number of +复数名词”,做主语时谓语动词为单数第三人称形式。

例如:

The number of books in our library is going up.我们图书馆里的藏书数量正在上升。

The number of the students in our class is 57. 我们班的学生人数为57人。

A number of students are playing football on the playground. 许多的学生在操场上踢足球。

5.The number of people who lost homes reached as many as 250000. 无家可归的人数达到25万。

短语“as many as” 意思为“和…一样多,多达”,修饰可数名词;as much as 与as many as 意思相同,但是修饰不可数名词。类似的表达法还有:

as long as 长达 as high as 高达 as wide as 宽达

The great fire burned down as many as twenty buildings. 那场大火烧毁的房屋达到20之多。

He lost as much as 1000 yuan . 他丢的钱多达1000元。

The film lasts as long as two hours. 这部电影长达2个小时。

The mountain reaches as high as 2000 metres. 那座山高达2000米。

The road is as wide as 10 metres. 这条路宽达10米。
