本题的做题方法基本和上一题型思路一致,分析句子成分是关键。现主要讲构词法。
英语单词的构成有一定的规律,这种规律称为构词法。掌握构词法知识对我们更好地理解词义、认识新词和扩大词汇量有重要意义。
构词法主要有三种:派生法、合成法和转换法。
一、派生法
在一个词的词根前面或后面加上某个词缀来产生新词,这种构词法称为派生法。词缀分为前缀和后缀。
(一)后缀:许多名词、形容词、副词和动词是由词根加后缀构成的。
1.构成名词的常用后缀有:
1-er, -or, -ist, -ee, -ian, -ese, -ant等用于构成表示人或物的名称。
:writer, translator, trainee, employee, scientist, physicist, musician,
physician, Italian, Asian, Chinese, assistant等。
2-ance, -ence, -(a)tion, -sion, -al, -ing, -ity, -ment, -th, -ty, -ure,
-ship等用于构成表示行为、性质、状态等的抽象名词。
如:acceptance, assistance, dependence, confidence, repetition, preparation,
discussion, division, arrival, survival(务必区分survivorsurvival, approval,
disapproval, building, reality, simplicity, ability, rapidity, regularity,
argument, warmth, length, growth, safety, leadership, failure, pressure,
friendship等。
3)其他名词后缀:-hood, -ness, -ology, -phy
如:childhood, neighborhood(附近,街坊), motherhood(母性,母亲身份), kindness, happiness,
sadness, biology, psychology, philosophy, geography

_______ surprised all of us.A survivor, survivorB survival, survivalC
  survival, survivorD survivor, survival【答案】D
【解析】本题考查survive变成名词时加不同后缀时含义的区别,即survivorsurvival的区别。survivor意为"幸存者"survival意为"幸存,生存",故选择D。【知识点】名词后缀
2. 构成形容词的常用后缀有:-able, -ible, -al, -ful, -less, -ish, -ive, -ous, -an, -ic, -ly,
-y, -ant, -ent, -ary, -en等。
如:available, suitable, valuable(注意联想invaluable, valueless, priceless,
responsible, natural, national, powerful, helpful, faithful, successful,
fearless, useless, helpless, selfless, selfish, childish, decisive, famous,
continuous, African, American, European, scientific, historic, friendly, lively,
thirsty, noisy, pleasant, dependent, consistent(一贯的), imaginary, golden,

fill in the blank.His advice is of great value to the successful completion of
our task. That is, his advice is _______ (valuable) to the success of our
  task.A invaluablyB valuablyC invaluableD valueless【答案】C
【解析】本题考查形容词词缀。valuable前面加了前缀in-并不表示否定含义,而是意义被强调了,可以说invaluablevaluable的强调形式,意为"无价的",相当于priceless;而valueless意为"无价值的",故选择C。【知识点】形容词词缀
3. 构成动词的常用后缀有:-ise/ize, -en, -ify等。
如:modernize, realize, widen, strengthen, beautify, modify(修饰)等。
4. 构成副词的后缀有:-ly, -ward(s), -wise。例如:completely, rarely, truly, simply,
backward(s), forward(s), clockwise, likewise同样地
补充:绝大部分形容词变为副词时直接加ly,但也有特例。
关于形容词变副词现强调以下几点:
1)形容词是"-le"结尾的,先去掉e,然后直接加y。例如:simply, possibly, subtly
2)形容词是"辅音字母加y"结尾的,先把y变成i,然后再加ly。例如:luckily, heavily
3)形容词是"l"结尾的,直接加ly。例如:finally, eventually, successfully
4true - truly

fill in the blanks________ (lucky), he has carried out the project _______
(complete) ahead of schedule.A Luckiness, completelyB Luckily, completelyC
  Luckily, completionD Unluckily, completly【答案】B
【解析】本题考查副词后缀。本句中第一个空格要填入的单词作状语,修饰整个句子,故选择副词,排除A。第二个空格处要填的单词修饰动词短语carry out the
project,因此同样选择副词,completely为正确拼写形式,故选B。【知识点】副词后缀
(二)前缀
1. 表示相反意义的前缀有:un-, dis, -in, -im, -ir, -il, -de等。
