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。

　　参考答案及解析：

　　巩固与拓展

　　1. relative -> relatively

　　2. ultimate -> ultimately

　　3. nation -> national

　　4. original -> origin

　　freely -> free 此处的意思是“免费的”，而不是“自由地”。

　　综合训练

　　1. after -> before

　　根据上下文逻辑，此处显然指孩子学会说话之前的听力，而非之后。

　　2.like -> as

　　like和as都有“像”的意思，但是此处要求填入一个具有“作为”之意的词，故将like改为as

　　3.in -> by

　　4. lead -> leads

　　此处句子的主语是上一行的attempt，所以要用动词的第三人称形式。

　　5.noise -> noises

　　One or two 后修饰的名词按复数对待。

　　6. particular -> particularly

　　修饰形容词indicative应该使用副词particularly。

　　7. can be said -> can not be said

　　8. from前加that

　　it是句子 的形式主语，而后面的from about three months they play with sounds for enjoyment才是真正的主语，too是插入语，由于是主语从句，故引导词that不能省略。

　　9. making -> made

　　此处指“发出的声音和说的话”，sound与make之间是被动关系。

　　10. which前加at

　　定语从句的关系代词指代先行词point，可知从句中缺少的时状语，因此在which前加at。
