我刚到家就开始下雨了。

【拓展延伸】1)在以never, hardly, scarcely, seldom, little, barely, nowhere, by no means, not until, hardly(scarcely)...when, no sooner...than等否定或半否定意义的词位于句首，表示强调的句子时，句子一般采取倒装形式。

如：Little do I dream of seeing such wonderful scenery.

我梦想不到会看到这样神奇的景色。

Hardly had he entered the house when it began to rain.

他一进屋，天就下雨了。

No sooner had he finished his homework than the light went out.

他一做完作业，灯就熄灭了。

2)注意当这些词不提到句首或作形容词修饰主语名词而置于句首时，句子不用倒装。如：

He had hardly finished his homework when the light went out.

他一做完作业，灯就熄灭了。

4. It was while at the New York School of Art that he experimented with different materials such as cloth and plastic in his paintings.

正是在纽约艺术学院这段时间，他在其绘画作品中尝试采用不同的材料，如布和塑料。

【巧解句构】It is/was...that...是强调结构，用来强调句子的某一成分。被强调的句子成分通常是主语、宾语或状语。被强调的部分指人时用who或that均可；指事物或情况时，通常用that。

【要点剖析】1)被强调的代词的格应与原句的格一致：如果被强调的代词是原句的主语，就用I, we, he等；是宾语就用me, us, him等。

2)被强调的部分如果是原句的主语，that/who后的谓语动词在人称和数上应和原句的主语一致。如：

It is I who am leaving for London next week.

下周去伦敦的是我。

3)被强调的部分是时间状语或地点状语时，不用when或where，而用that。如：

It was in Qingdao that we met for the first time.

我们首次相见是在青岛。

【记忆要诀】 注意区分强调句和其他从句。如果把it is...that...去掉，句子还成立，就是强调句。

【辨析比较】 such as与for example

such as用来列举事物，常用在列举的事物和前面的句词之间，但是所列举的事物的数量不能等同于之前所提事物的总数，否则应用that is 或namely;

for example主要用来举例说明，一般只列举同类人或事物中的"一个"，其位置比较灵活，可置于句首、句中或句末，用标点符号隔开，而such as只能放在所列举事物之前。如：

He knows several languages, such as English, French and German.

他懂几种语言，像英语、法语和德语。

I have three friends, that is/namely, John, Jack and Tom.

我有三个朋友，即约翰、杰克和汤姆。

Some students, for example, John, lives in the neighbourhood.

有些学生，比如约翰，住在附近。
