考生在考试中经常会遇到这样一种现象,在题干中遇到了一个teenager,但是在文章中找对应信息的时候,出现的却是young people;题干中遇到的是punctually,文中对应的是on time。这个就是PET考试中一个常见的考点,同义替换。
同义替换,简单来说,有时可以是名词替换名词,动词替换动词。这种情况比较简单。但是有时候,还会出现另外一种情况,例如题干中是 on busy school roads, 文章当中是heavy traffic in towns and cities。你会发现它的结构整个是不一样的,一个是介词短语,一个是名词性结构,这种同义替换相对来说难度更大一些。
对于考生来说,主要的一个难点就是单词基本认识,就是选不对答案。因此想要掌握同义替换,需要进行大量的练习。
在PET阅读中,同义替换有四种典型的方式:
1.同义词之间的替换
题目:Feeding increasing populations is possible due primarily to improved irrigation systems.
原文:Food production has kept face with soaring population mainly because of the expansion of artificial irrigation system that make possible the growth of 40% of the world’s food.
分析:此题出现的同义词替换包括:
feeding → food production
due primarily to→mainly because of
improved irrigation systems→the expansion of artificial irrigation system.
典型的同义词替换:
change →shift / revision
metropolitan →city
overstate →exaggerate
expert →scientist / specialists
target →goal
decrease→crash / halve
comments →feedback
hard to find →elusive
like → resemble
2.同根词词性的替换
题目:They use their own natural secret antibiotics as weed-killers and also use unwanted materials as fertilizers.
原文:Farmer ants secrete antibiotics to control other fungi that might act as ’weeds’, and spread waste to fertilize the crop.
分析:此题中出现的同根词词性替换包括:
secrete antibiotics → secretion
fertilizer →fertilize.
3.否定加反义词之间的替换
题目:In principle, it is possible for a biological system to become older without ageing.
原文:Thus ageing and death should not be seen as inevitable, particularly as the organism possesses many mechanism for repair.
分析:题干中possible是原文not inevitable的否定加反义替换。
典型的否定加反义词替换:
downward →not rising
not traditional →radical new approaches
with no rain at all →droughts
4.上下义词的替换
所谓上下义,是指替换的词语之间通常有一种从属关系。题目中给的是一个具有属性或者是表示概念的词语,而在原文中出现的替换词却是一个具体或者是细节的信息,此类替换考察的是考生对这两者之间从属关系的配对。
题目:Studies show drugs available today can delay the process of growing old.
原文:As researchers on aging noted recently, no treatment on the market today has been proved to slow human aging—the build-up of molecular and cellular damage that increases vulnerability to infirmity as we get older.
分 析:原文中treatment即为题干中drugs的上义词。
