句型梳理
1【教材原句】 They are often so thick that you cannot see the sun，and the wind is sometimes strong enough to move sand dunes.(P32)
沙尘暴经常是非常混浊的以至于你看不见太阳，而且风有时大得能够刮动沙丘。
【句法分析】 so...that...“如此……以至于……”，引导结果状语从句。
so...that和such...that引导的结果状语从句都表示主句的动作或状态达到一定程度而引起的结果。so是副词，用来修饰形容词、副词、分词或其他结构；such 是形容词，用来修饰名词或名词短语。such 修饰单数可数名词且名词前有形容词时，可用so替换such，冠词与形容词交换位置，构成“so＋adj.＋a(an)＋名词”。名词前有many，much，few等表示数量的词时，一般用“so...that...”句型。
so...that...和such...that...构成以下句型：
但little意为“小的”时，只能用such。为加强语气，“so(such)．..that”结构中的so或such位于句首时，主句要用部分倒装语序。例如：
①He spoke in so low a voice that none of the people in the hall heard what he was saying.
他讲话的声音那么小，以至于大厅里的人都没听清他在讲什么。
②It is such fine weather that we all want to go to the park.
今天天气很好，我们都想去公园。
③He earned so little money that he couldn’t support his family.
他挣的钱很少，以至于不能养家糊口。
④So fast did he walk that none of us was his equal.

A．so that B．in order that C．because D．now that
解析：选A。so that引导一个结果状语从句，表示“结果盖子扣不死了”。
15.He is________a careless boy that he has made________many mistakes in the final exams.
A．such；such B．so；such C．so；so D．such；so
解析：选D。本题考查such和so两个词的用法。第一空考查的是such＋a＋adj.＋可数名词单数＋that从句，意思是“如此……以至于”；第二空考查的是so＋many/few＋可数名词，意思是“如此多/少的……”。故选D。
2【教材原句】 The garbage is then taken away and, if possible，recycled.(P39)
然后垃圾被带走，如果可能的话会进行回收利用。
【句法分析】 (1)if possible是if it is possible的省略形式。当if，when, while，until，unless，once，whether等引导的状语从句的主语与主句的主语相同，并且从句中含有系动词be的某种形式时，或从句的主语是it且含有be动词时，从句中的主语及部分谓语(be动词)可省略。
(2)if引导省略的情况有下列几种：
if any如果有的话
if necessary如果需要的话
if so如果是这样的话
if ever如果曾经有的话
if not 如果不这样的话
①Unless necessary，you’d better not refer to the dictionary.
你最好别查字典，除非有必要。

如果可能的话，我想避开交通高峰期。
