高一二部英语学案必修一第一单元重点句型

编辑：侯立新审核：

1.I wonder if it is because I have not been able to be outdoors for so long that I have grown so crazy about everything to do with nature .

[分析]

a.本句的结构是：主语（I）+ 谓语（wonder）+宾语从句（if ...nature）

b. 宾语从句中的it is ... that ... 为强调句式，其基本结构是：It is / was + 被强调部分(常是主语、宾语或状语) + that / who（强调主语且主语指人时可以用who，也可以用that）+ 其它部分。

强调句式只是把句子中的某些成分（被强调的部分）改变位置，所以把强调结构（it is / was ... that / who）去掉之后，句子一定是完整的。如：

It was yesterday that he met his classmate.

（He met his classmate yesterday.）

a.wonder +if /whether 等引导的并与从句我想知道…

I wonder if you can help me repair my bike.

I wonder whether you can help me or not .

I wonder what your hobby is

b. it is …that …为强调句式，主语，宾语和状语以及从句

It is miss Liu who/ that is my teacher.

It is English that I like.

It was him who/ that I met in the street yesterday.

It was in the street that I met him yesterday.

Was it I that met him in the street yesterday?

Who was it that met him in the street?

c.have something to do with …和…有关系

2. it was the first time in a year and a half that I dad seen the night face

to face

a. it is the first time that I have done …

b.it was the first time that I had done

I can well remember that there was a time when a deep blue sky, the song of the birds, moonlight and flowers could never have kept me spellbound.

3.There was a time when …＋定语从句有一段时间……

[分析]

4.a. 本句的结构是：主语（I）+ 谓语（can well remember）+ 宾语从句（that ... spellbound）。

b. 宾语从句中的there was a time when ... 是一个固定句型，意为“这/ 那时发生了……”，time在本句型中指一段时间，后面跟了一个由when引导的定语从句。如：There was a time when I did not want to go to school.

There was a time when I often came to school by bus.

I remember the days when I lived happily in the country.

4. I happened to be upstairs at dusk when the window was open

a.happen to do /be 碰巧做……

I happened to meet him in the street.

He happened to be sleeping when I came in.

b. It happened that ……是偶然的主语从句

It happened that I met him in the street.

It’s no pleasure looking through these any longer because nature is one thing that really must be experienced.

[分析]

a. 本句的结构是：形式主语（It）+ 系动词（is）+ 表语(no pleasure) + 真正的主语(looking through these any longer) + 原因状语从句(because nature ... be experienced)。

b. 在原因状语从句中，that really must be experienced是定语从句修饰先行词thing。
