Sentence Pattern
重点句式 s that“为了，以便”，引导目的状语从句
(教材P20)Is it right t make animals hmeless s that humans can have mre paper?
让动物无家可归，以便让人类有更多的纸，这样做对吗？
[句式分析]
(1)s that从句中常使用情态动词can/culd，may/might，will/wuld等。s that引导的目的状语从句不能放于句首，而in rder that引导的目的状语从句既可放在句首，也可放在主句之后。
(2)当s that或in rder that引导的目的状语从句中的主语与主句的主语一致时，从句可变为s as t或in rder t的动词不定式短语。
[例1] We turned n the light s that we might see what it was.
我们把灯打开，以便看看它是什么。
[例2] Speak clearly s that/in rder that they may understand yu.
讲清楚些，以便他们能理解你。

写出s that从句所作的成分/一句多译
①We turned up the radi s that everyne culd hear it.
目的状语
②They wrked very hard，s that they finished the wrk befre supper.

③他提高了嗓门，以便大家都能听到。

分辨字面意义和隐含意义
字面意义指词的确切的、字面的意义；隐含意义指词的隐含的引申的意义。隐含意义包括词的感情意义、搭配意义、文体意义和不同的风格等，学生在做词义猜测题时，要注意联系画线单词的字面意义和隐含意义。

A．easily brken B．easily fund
C．expensiveD．heavy
A [词义猜测题。根据画线词后所给的例子“like thse made f glass”及段末的“pieces”可知，画线词指“易碎的”，即easily brken。]
