Step IV. Language using 1.“It＋be/动词＋时间段＋before”结构，意为“在……之后……才……”

I developed very slowly and it took nearly two hundred years before I was built as an analytical machine by Charles Babbage.(教材P18) 我发展很慢，差不多到了两百年之后，查尔斯·巴比奇才将我制成了一台分析机。

【句式点拨】

before引导的时间状语从句，意为“过一段时间后才/就……”；若主句为将来时，从句则用一般现在时；若主句是一般过去时或过去完成时，则从句用一般过去时。

(1)before 引导时间状语从句时，除了译成“在……之前”之外，还可表示“还没来得及……就……”，目的在于强调从句动作发生之前，主句动作已发生。

(2)“It＋be＋时间段＋since”引导的时间状语从句，表示“自从……已经有多长时间了”。主句用一般现在时或现在完成时。

①It will be half a year before you graduate from the school.

再过半年你才能毕业。

②It was not long before he sensed the danger of the position. 不久他就意识到他处境的危险。

③It is three years since she came to our class. 她来我们班已经有三年了。

2. as 引导的时间状语从句

As time went by, I was made smaller.(教材P18) 随着时间的推移，我被做得更小了。

【句式点拨】

本句中as 是连词，引导时间状语从句，意为“随着……”。

【拓展延伸】

with(随着)是介词，后接名词或代词等构成with短语或with复合结构。

With time going (go) by, they became close friends. 随着时间的流逝，他们变成了好朋友。

3. so/such…that…如此……以至于……

And my memory became so large that even I couldn't believe it！(教材P18)

我的存储量变得如此之大，甚至连我自己都不能相信！

【句式点拨】

此句中so…that…引导结果状语从句，意为“如此……以至于……”，so是副词，后面要跟形容词或副词，其用法如下：

形容词或副词形容词＋an＋单数可数名词so＋

that…

many/few＋复数名词much/little少的＋不可数名词【拓展延伸】

an＋形容词＋单数可数名词＋that…(1)such＋形容词＋复数名词/不可数名词＋that…

(2)当so…/such…放在句首时，主句要用部分倒装。

①It was so hot a day that nobody wanted to do anything. ＝It was such a hot day that nobody wanted to do anything. 天气如此热，谁也不想干活。

②There were so many people in the street watching the fire that firefighters could not get close to the building.
