2019-2020年高三英語大一輪復習講義 語法知識 專題十二 構詞法 新人教版一、合成法合成法是把兩個或兩個以上的單詞合成一個新單詞的構詞法。有的可以直接寫在一起構成一個新單詞，還有的在詞與詞之間用連字符“”或空格隔開構成一個新單詞，把這個詞通常叫做復合詞。二、轉化法轉化法是由一種詞類轉化為一種或幾種詞類的構詞法。這種構詞法詞形沒有改變，轉化后的單詞在意義上通常與原單詞有密切聯(lián)系。三、派生法派生法是英語主要的構詞法。此方法是借助于前綴或后綴，制造出派生詞，主要有名詞、形容詞和動詞三種。1前綴構詞法前綴是加在一個詞根前面的音節(jié)，它并不是獨立的單詞，但本身有一定的含義，它不改變詞性，但改變原詞義。2后綴構詞法后綴是加在一個單詞后面的音節(jié)，它本身一般也有一定含義，能夠改變單詞的詞性，有的也可以改變詞義。備注：以上三種構詞法的具體例子見記憶有道中的構詞法記憶部分。用所給詞的適當形式填空1Her preparation course is helping her to get used to academic(academy) requirements of a Western university.2.A fireman accidentally(accident) discovered the cause of the fire.3It cost approximately(approximate) 300I cant remember it exactly.4.Beggars(beg) cant be choosers.5Other disabled people find the website beneficial(benefit) because they can read about people with similar difficulties to their own.6.She glanced casually(casual) through a magazine as she waited.7.He quit playing petitive(pete) football at the age of 24.8The caf has a relaxed continental(continent) feel about it. 9The man standing there is a distinguished(distinguish) novelist and philosopher.10It is a dramatic(drama) story about an invasion of the Earth by aliens from Mars.11The teachers are very enthusiastic(enthusiasm) and friendly and the classrooms are amazing.12.Building a new factory there would be environmentally(environment) disastrous.13.Yesterday we held a ceremony to wele the honorable(honor) soldiers who just came back from Wenchuan.14Tourists shouldnt miss the 103 bus which offers one of the most impressive(impress) routes.15You should loosen(loose) up your muscles before playing any sport.
