词性重点考查的就是词性的混淆,主要是名词与动词的误用、名词与形容词的误用以及形容词与副词的误用。做这类改错题,首先要判断词性及词在句中的位置,然后根据它们在句中所处的位置来确定词性是否正确。一般说来,形容词修饰名词,副词修饰动词,副词修饰形容词。例如说到某个问题的严重性,会用increasingly serious(越来越严重),用副词修饰形容词,不能说increasing serious。
考点例析:
例1:Most experts believe this can continue even if the population
doubles by the mid-21st century,although feeding I0 billion people
will not be easy for politics, economic and environmental reasons S6.___
解析:reasons有三个修饰词politics, economic, environmental , 后两个是形容词,第一个也应该是一致的,所以把politics改称political。
例2:Culture is essentially to our humanness. It provides a kind of S8.______
map for relating to others.
解析:做表语时,应该使用形容词而不是副词,故将essentially -%26gt; essential。
例3:Their experiments have shown that reading disorders are most
likely the result of what is, in effect, faulty wiring in the brain—
not lazy, stupidity or a poor home environment S4._____
解析:lazy, stupidity ,a poor home environment 是三个并列的词,在词性上应该保持一致,所以将lazy改成laziness。
