第四讲词性转换(构词法)英语构词法主要有三种：合成、转化和派生。合成是指将两个意思不同的单词结合成一个新词；转化是指一个单词的词形不变而由一种词性转化为另一种词性；派生是指通过给一个单词加前缀或后缀变成另一个词。前缀一般改变词义而不改变词性，后缀一般改变词性而不改变词义。将构词法置于此处讲解，一是对前面基础词法的汇总，二是为攻克后面的重难动词做铺垫。动词、形容词转换为名词 [全析考法]单句语法填空/单句改错1 ． (2018· 全 国 卷 Ⅱ )This switch has decreased ________ (pollute) in the country's major lakes and reservoirs and made drinking water safer for people.解析：pollution decrease“降低，减少”，为及物动词，后接名词作宾语，故填名词 pollution。2．(2018·6 月浙江高考)Researchers have found that there is a direct link between the increase in food eaten outside the home and the rise in ________(weigh) problems. 解析：weight 根据语境可知，此处表示体重方面的问题，故此处填名词作定语。3 ． (2017· 全 国 卷 Ⅲ )She is determined to carry on with her ________ (educate)．解析：education 前面有形容词性物主代词 her，此处应该使用动词 educate 的名词形式 education 作宾语。4．(2016·全国卷Ⅰ)Chengdu has dozens of new millionaires, Asia's biggest building, and fancy new hotels.
