本期重点：词性

　　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 -> 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。
