第一类,人称代词
人称代词主要包括:I,you,he,she,it,we,they,me,him,them,yours,his,her,its,their等。此类题型应在做题时根据代词的单复数及其所能指代的名词来判断,通常是往前找最近的核心名词。
例如:
“An auction is a popular way of buying and selling. It is a useful way of deciding the value of things。”
The word It in the passage refers to __________。
A. theory B. price
C. process D. auction
往前追溯单数形式的核心名词,并且能用在第二句的主语位置的词,就只能是第一句中出现的auction一词了,所以正确答案选D。
第二类,指示代词
指示代词主要包括this, that, these, those等。在这种句子中,this和that通常指代某个观点事物或现象,而these和those通常指复数形式下的某些观点事物或意见,并且该类题也遵循往前找的原则。
例如:
“The dragon also has large claws that are used when it is younger. It uses these to climb trees to escape from the jaws of older dragons. But when they get older, these claws are used mainly as weapons。”
The word these in the passage refers to __________。
A. claws B. trees
C. jaws D. weapons
该题中的these一定是指之前已经出现过的名词,所以现在才能用代词进行指示,因此我们首先可通过往前追溯的原则进行排出,B、C、D瞬间就都被排除了。再将A选项带入原句验证,看逻辑和意思是否与句意相符,最终验证表明,答案正是A选项。
第三类,关系代词
主要包括which, that, who, whom等。在这种句子中,通常采用就近原则。尤其是由“, which”格式引导的从句,一般都是非限制性定语从句,通常就是指该词前面紧挨着的名词。但需要注意的是,当关系代词前有插入语时,需要先去掉插入语,再使用就近原则。
例如:
“Scientists have been looking for energy sources to replace oil. They have studied wind,ethanol,and nuclear energy. They have also started to look at coal again. Coal,which is the cheapest energy source,is found in many parts of the world. However,it is dangerous to mine. It also pollutes the environment。”
The word which in the passage refers to __________。
A. nuclear energy B. ethanol
C. wind D. coal
一看词句考察的是由which引导的非限制性定语从句,则毫不犹豫得把答案定位到which前的名词“coal”上,所以一眼就能选出该题的正确答案D选项。
第四类,不定代词
主要包括some,any,every,each,none,some...others...,one...,another等。这类代词通常指的都是该词前后与其关系最紧密的名词主语,并且注意词的单复数形式。
例如:
“Some studies show that one in eight plant species is threatened with extinction. It is estimated that 140000 species of plants are lost each year. Many of these lost plants could have been very useful in creating new drugs to combat disease。”
The word Many in the passage refers to __________。
A. studies B. plant species
C. lost plants D. new drugs
首先确定该题的“Many”所在句主语应该是指“lost plants”,并且“of”是表示所属的关系,所以“Many”应该是属于“these lost plants”中的一部分,所以很显然“Many”指的就应该是“lost plants”,因此答案选C。
