29、noon, sportsman, blackboard, sportsperson, newspaper, airplane, classmate, grandfather 等就是通過合成構(gòu)詞法構(gòu)成的名詞；kind-hearted, middle-aged, hard-working 等為合成形容詞；however, maybe, himself, everyone, nothing, overlook 等也都是通過合成法構(gòu)成的單詞。2. 派生法通過在詞根前面加前綴或在詞根后面加后綴構(gòu)成一個新詞的方法叫作派生法。要通過派生法理解和記憶單詞, 我們需要掌握常見的前綴和后綴及派生規(guī)律。(1) 常見

30、前綴前綴含義例詞dis-不disagree, dislikeen-使處于某種狀態(tài)enable, enrichim-, in-不impossible, impatient, inexpensiveinter-在之間, 相互international, interconnectmis-錯誤地mislead, misunderstandnon-不, 非non-smoker, non-nativere-再, 重復(fù)rewrite, retellun-不unable, unhappy, unpopular(2) 常見后綴后綴功能例詞-er, -or構(gòu)成名詞teacher, worker, visitor-

33、arefully, carelessly, happily, quickly(3) 派生規(guī)律由一個詞根加上相應(yīng)的詞綴可以派生出名詞、形容詞、副詞等，掌握派生規(guī)律對擴充詞匯有很大幫助。例如：由 interest 可以派生出： uninterestinginterest interesting interestingly interested uninterested由 help 可以派生出： helpless helplesslyhelp helpful helpfully由 able 可以派生出： enableable unable ability disable3. 轉(zhuǎn)化法英語構(gòu)詞法中把一種

34、詞性轉(zhuǎn)化為另一種詞性而詞形不變的方法稱作轉(zhuǎn)化法。常見的轉(zhuǎn)化有：(1) 動詞轉(zhuǎn)化為名詞 Lets talk about it more. 咱們再談?wù)勥@件事吧。 I think wed better finish the talk now. 我想我們最好現(xiàn)在結(jié)束談話。(2) 名詞轉(zhuǎn)化為動詞 She gave me a cup of water. 她給了我一杯水。 You should water the flowers twice a day. 你應(yīng)該每天給這些花澆兩次水。 (3) 形容詞轉(zhuǎn)化為名詞 She was wearing a black dress. 她穿著一條黑色的裙子。 The gi
