2020届二轮复习(六)词性转换(构词法)

‎2020届二轮复习 (六) 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.

Yesterday my friend Tony, together with me, decide to go swimming in the sea. It was turned out to be one of the most exciting experience I had ever had. At first, seeing the waves come one after another, I felt frightened. As I was a good swimmer in the swimming pool, swimming in the sea was a little difficult for him. I was just about to give up when I suddenly noticed little boy walking towards the sea calmly. Weak as he seemed, he went straight into the sea with hesitation. Deep encouraged by his behavior, I overcame my fear and finally made a successful attempt.‎ 答案:第一句:that→where 第二句:decide→decided 第三句:去掉was; experience→experiences 第四句:come→coming 第五句:As→Although/Though; him→me 第六句:little前加a 第七句:with→without 第八句:Deep→Deeply
