　　In evolutionary history, the development of language set humans apart from the rest of the animal kingdom. Which sentence below best expresses the essential information in the highlighted sentence in the passage? Incorrect choices change the meaning in important ways or leave out essential information.

　　A. Humans evolved as the most powerful species after they are developed language.

　　B. The creation of human language has its origins in the language of animals.

　　C. The emergence of language distinguished early humans from other animals.

　　D. Humans and animals developed completed different systems of communication.

　　先来看题干：Which sentence below best expresses the essential information in the highlighted sentence in the passage? Incorrect choices change the meaning in important ways or leave out essential information.

　　该题请求从选项中挑选一个能够表达原文暗影语句中心信息的语句。许多同学选用翻译的方法做题，即首要翻译原句，然后逐一翻译四个选项。这种做法不仅浪费时刻，而且对咱们读语句的才能请求极高。非常好的做法是，首要判别语句的中心信息。这是考题傍边为数不多的原句比较简略的语句释义题，原句的中心概念在于强调区别(apart from)。因而找到同义更换，便是C 项傍边的distinguished。但是大多数标题的原文不会是一个简略句，多数是带有逻辑联系的杂乱句。那么简略的同义更换窍门就无法操作了。怎么疾速处理这种题型呢?咱们首要分两个部分来解析。

　　本来，咱们在读原句的时分并不需要完好的完全的摄取信息，相反，咱们经过疾速阅览，只需要重视两个要害点：一是原句傍边的表明程度，频率的词，二是原句傍边的逻辑联系。并不需要吸收所有信息，只需要疾速阅览将所重视的信息点捉住即可，这么便节省了大量的时刻。

　　The extreme seriousness of desertification results from the vast areas of land and the tremendous numbers of people affected, as well as from the great difficulty of reversing or even slowing the process. Which sentence below best expresses the essential information in the highlighted sentence in the passage? Incorrect choices change the meaning in important ways or leave out essential information.

　　A. Desertification is a significant problem because it is so hard to reverse and affects large areas of land and great numbers of people.

　　B. Slowing down the process of desertification is difficult because of population growth.

　　C. The spread of deserts is considered a very serious problem that can be solved only if large numbers of people in various countries are involved in the effort.

　　D. Desertification is extremely hard to reverse unless the population is reduced in the vast areas affected.

　　解题思路：

　　语句中最中心的信息首要即是该句的逻辑联系。原句的逻辑联系能够由result from 来判别，为因果联系。借此咱们就能够减小选项规模，首要扫除去C,D 选项。剩余的A,B 两个选项均包含因果的逻辑联系。接下来咱们能够依据语句的第二种中心信息：主语，来判别。原句的主语是Desertification 沙漠化，而B 项的主语是Slowing down the process of desertification 减缓沙漠化进程。所以扫除去B 选项，A 为准确答案。

　　将经过程度词解题和凭仗逻辑联系解题结合起来，关于回答带有逻辑联系的杂乱句的释义题很有协助。咱们看下面这道标题：

　　It is one of the most important sensations because it is translated into a negative reaction, such as withdrawal from danger.

　　Which sentence below best expresses the essential information in the highlighted sentence in the passage? Incorrect choices change the meaning in important ways or leave out essential information.

　　A. Escaping from danger is a negative reaction, but it is the most important thing an individual learns.

　　B. The ability to sense pain is extremely important because pain signals the body to respond to a threat.

　　C. Experiencing pain is one type of reaction to a negative stimulus; another type is avoiding danger.

　　D. We experience a lot of sensations, and the most important ones are translated into appropriate actions.

　　阅览原句，从because 能够看出逻辑联系为因果联系，而且原句傍边有绝对化词汇most。只是凭仗most 这个程度很强的词汇咱们能够扫除C 选项。由于原文傍边带有绝对化词汇而选项中没有，那么这个选项为必错选项。接下来使用逻辑联系扫除A 项，A 中为转机联系。而B 恰恰有because 这个词，此外B 中的extremely 能够作为most的同义更换。准确答案为B。

　　简直每一篇文章后边都会有一道释义题，因而考生应加强练习。平常在阅览文章，或许报刊杂志的时分不只是要把留意力放在读懂原文上，还应该留意原文的逻辑联系，培育依据逻辑联系考虑的习气。另外，一些程度词的存在也会影响咱们对原文的准确了解，平常阅览的时分应当多加重视。
