托福阅读句子替换题的技巧
TYPE7 句子替换题
句子替换题比较考察内功，读长句的能力。那么有没有空子可以钻呢?答案是有，很有!
这类句子一般都很长，长句怎么构成，需要很多从句填充，需要连词连接两个句子，需要有逻辑词表达句意，我们的突破口，就放在逻辑词上面。
无耻技巧1
找到句子中的逻辑词，然后对照选项，如果只有一个逻辑词与之相符合，那么直接选，无需看答案。
Eg
Although management was pleased with the toughness that Truman had shown and many citizens were pleased that disruption of the economy had been avoided, concern was expressed about the constitutionality of having congress that such a step.
A Though some were pleased that Truman had kept the economy going, there was concern about how he had done it.
B During the strike, the economy was disrupted, and congress was forced to take steps to fix it.
C Because of the effects of the strike on the citizens of the country, it was necessary for congress to make changes to the consititution.
D Management took tough actions during the strike; as a result, congress expressed concern about the steps that management had taken.
有的同学拿到了这个句子之后，开始惆怅，开始压抑，这么长，看着都烦了
怎么读!!!
我告诉你，不读，看见although，往下看米有逻辑词了，去看选项吧，
A though 也转折
B 没有逻辑词
C 因果
D因果
直接选A，对
就这么无耻!!!
无耻技巧1小贴士：对于这个技巧有一个补充，就是对于因果逻辑关系，选项中往往会设置几个因果逻辑的句子，这时我们要区分哪一部分是因，哪一部分是果，通常会有把因果调过来的迷惑选项
看例题
During that period of time, because of the huge glaciers, sea levels were as much as 100 meters lower than they are today.
A since the Ice Age, the amount of water in the oceans has decreased dramatically
B During the Ice Age, sea levels were low because of how much water was frozen.
C Glaciers have grown tremedously since the last Ice Age
D During the Ice Age, huge glaciers displaced a lot of water, causing the oceans to rise.
第一步，找逻辑词，because of，因果逻辑。
有同学一看选项，选A，since!这就是我说的学东西学的太死了，since在这里根本不是因为的意思，而是自从。
A没有逻辑词
B 有因果，保留
C 无逻辑词
D causing 有因果
这样是剩下BD，现在开始使用小贴士，看原句，huge glaciers 是因，BD都正确，sea levels 下降了，是果，D的结果是rise，与原文相反，排除掉，选择B
以上所写，是这类题中较简单的类型，难题是什么样呢，思路和方法是一致的，只是有两三个逻辑，相当于简单类型的堆砌。这个时候我要注意区分主逻辑和次要逻辑。在条件句中，结果是重要的，条件不重要!
Eg：我不会嫁给他的，because if 我嫁给了他，我的上司就会不器重我了。
原文 托福阅读应试技巧之句子替换题
有同学看到了because表示因果，又看到了if表示条件，分不清哪个才是主要逻辑。
来一起分析下，之前讲过的读句子的`方法，挑主干，主干是，我不会嫁给他。
Because是连词，连接一个if引导的条件句，那么看这个条件句，if我嫁给了他是从句，主句是我的上司就会不器重我了,主干，要表达的就是我的上司不器重我。
两个句子的主干都挑出来了，那么化简一下这句话：我不会嫁给他的，因为这会导致我的上司不器重我。
看英文例子：He refused to develop projection technology, reasoning that if he made and sold projectors, then exhibitors would purchase only one machine-a projector-from him instead of several.
○Edison was more interested in developing a variety of machines than in developing a technology based on only one.
○Edison refused to work on projection technology because he did not think exhibitors would replace their projectors with newer machines.
○Edison did not want to develop projection technology because it limited the number of machines he could sell.
○Edison would not develop projection technology unless exhibitors agreed to purchase more than one projector from him.
第一步，挑出逻辑词，reasoning that和if 一个表因果，一个表示条件，上面解释过了，
因果是主逻辑，
A 无逻辑词
B 有because
C 有because
D unless是条件，排除
一起看BC选项，因部分都是正确的， B的果里面有一个newer machines. 原文没提的排除掉，C选项的limited the number of machines he could sell.是purchase only one machine-a projector-from him instead of several.的同意转述，选择C
无耻技巧2
关于however的处理，当however 出现在主语，谓语之间或谓语 宾语之间时，把however提到句首，翻译成但是，在本句中无地位不表示逻辑，对本句无任何影响，而表示本句话与上句话之间是转折关系。
Eg 我深深地爱着你。你，however，爱着一个SB。
等价于 我深深地爱着你。However，你爱着一个SB。
所以，第二句说的只是你爱着一个SB!
总结一下句子替换题;首先挑出句子的逻辑词，确定主逻辑，对照选项排除，然后看是否改换了句子的主干。
