自古深情留不住，
唯有套路得人心。
句子看半天反而选了错误选项？
不如试试大诗姐的套路，
来做出句子简化题哦！
教你一招做出托福阅读中的句子简化题！
主文丨托福阅读
句子简化题的原句很长，4个选项也都很长，很多同学做这种题时会看到地老天荒。最后及时选对了，可耽误了大量时间；更别提常常看着看着就看到沟里，选了错的迷惑项了。
其实自古深情留不住，托福阅读中，你看再多再仔细，并不能帮你提高正确率。套路才能帮你一招制胜、找到重点。
先来看看题吧：Official17-2 Animal Signals in the Rain Forest-07-句子简化
In the green-to-yellow lighting conditions of the lowest levels of the forest, yellow and green would be the brightest colors, but when an animal is signaling, these colors would not be very visible if the animal was sitting in an area with a yellowish or greenish background.
选项：
A.When an animal is signaling in an area with green-to yellow lighting condition, It’s signal will not be visible if the background is brightly lit.
B.In the lowest levels of the forest, an animal's signals are not easily seen unless there is a yellowish or greenish background.
C.In the green-to-yellow lighting conditions at the lowest levels of the forest, only signals that are themselves green or yellow will be bright enough to be seen in most areas.
D.Although green and yellow would be the brightest colors near the forest floor, these colors would make poor signals whenever the forest background was also in the green-to-yellow range.
分析：
1.主要逻辑
In the green-to-yellow lighting conditions of the lowest levels of the forest, yellow and green would be the brightest colors, but （主要逻辑，相反，并列句，在缩减完的正确答案中必须有且必须对）when an animal is signaling, these colors would not be very visible if the animal was sitting in an area with a yellowish or greenish background.
2.并列句分析
并列句一（but之前）：
In（介词短语，简化后可有可无） the green-to-yellow lighting conditions of the lowest levels of the forest, yellow and green would be the brightest colors（这是主句，简化后必须有）
中间有个主要逻辑but转折。
并列句二（but之后）：
when（从句，简化后可有可无） an animal is signaling, （these colors would not be very visible这是主句，简化后必须有） if （从句，简化后可有可无）the animal was sitting in an area with a yellowish or greenish background.
所以简化后句子中必须有：黄绿最亮，但是，这些颜色不太可见。
3.正确选项核对
D.Although green and yellow would be the brightest colors near the forest floor, these colors would make poor signals whenever the forest background was also in the green-to-yellow range.
4.错项分析
A.When an animal is signaling in an area with green-to yellow lighting condition（并列句一主句改写）, It’s signal will not be visible if the background is brightly lit（勉强可算并列句二改写）.但其实以上都不用看，你的脑海中只有一件事：主要逻辑呢？？？？并列句一和二之间是转折啊！！！转折呢？
B.In the lowest levels of the forest（并列句一的介词短语）, an animal's signals are not easily seen（并列句二when从句和主句） unless there is a yellowish or greenish background（并列句二if从句）.没有转折，没有没有并列句一的主句，原文并列句二内部的逻辑是if（一致）！而这里出现unless（相反）！
C.In the green-to-yellow lighting conditions at the lowest levels of the forest, only signals that are themselves green or yellow will be bright enough to be seen in most areas.这选项纯属考官编不出来了瞎写的，我懒得讲了。而且还有only。这不典型一看就其中有诈嘛！（正课第二次直播是不是强调了半天）
所有的逻辑关系，追根究底，只分成两种：
一种叫一致，一种叫相反。
一致之间可能互相转化；
相反之间可能互相转化；
但是一致和相反不能互相转化！
好啦，方法学会了，赶紧用学到的内容试答一下其他简化类的真题吧！
