usualwantedwaste構(gòu)詞法1.合成法將兩個或兩個以上獨(dú)立且語義不同的單詞合在一起構(gòu)成新詞的方法叫做合成法。合成法是一種比較靈活的構(gòu)詞方法，可以合成名詞、形容詞、副詞、代詞、動詞等。例如：afternoon,sportsman,blackboard,airplane,grandfather等是通過合成構(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也都是通過合成法構(gòu)成的單詞。新課講授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,要掌握常見的前綴和后綴及派生規(guī)律。1)常見前綴前綴含義例詞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,interconnectSummarizetherulesofprefixandsuffixword-formation.派生法是英語主要的構(gòu)詞法。這方法是借前綴或后綴產(chǎn)生出派生詞，主要有名詞、形容詞和動詞三種。前綴以否定前綴un-、in-、im-、il-、ir-、non-、dis-、mis-等為主，使單詞延伸出來的派生詞變成其反義詞。例如：injustice(不公平的)、unhappy(不高興的)、impossible(不可能的)等。(1)名詞派生詞

balance(平衡)→imbalance(不平衡)；pleasure(高興)→displeasure(不高興)；

management(管理)→mismanagement(管理不善)；efficiency(功效)→inefficiency(無效率)等。Summarizetherulesofprefixandsuffixword-formation.

(2)形容詞派生詞accurate(精準(zhǔn)，正確)→inaccurate(不正確)；patient(能忍耐的)→impatient(無法忍耐的)；regular(有規(guī)矩的)→irregular(不規(guī)矩的)；legal(合法的)→illegal(違法的)等。(3)動詞派生詞agree(贊同)→disagree(不贊同)；judge(判斷)→misjudge(對……判斷錯誤)；treat(款待)→mistreat(虐待)等。新課講解4CompletethesentenceswiththecorrectformofthewordsinActivity3.Shewashopefulthathernewjobwouldmakehermoresuccessful.1.Thefactory________theriver,andthefishdied.2．Weoftenwalkinthecountryside.Itisa(n)
