連線

1..截取法:將單詞縮寫(xiě)，詞義和詞性保持不變的英語(yǔ)構(gòu)詞法稱(chēng)為截短法，主要有截頭、去尾、截頭去尾等形式。1）截頭telephone→phone電話

airplane→plane飛機(jī)2）去尾mathematics→maths數(shù)學(xué)examination→exam考試kilogram→kilo千克laboratory→lab實(shí)驗(yàn)室taxicab→taxi出租車(chē)3）截頭去尾influenza→flu流感refrigerator→fridge冰箱prescription→script處方藥方腳本

二、截取混合縮略法2.混合法:英語(yǔ)構(gòu)詞還可以將兩個(gè)詞混合或各取一部分緊縮而成一個(gè)新詞，前半部分表屬性，后半部分表主體。這樣的英語(yǔ)構(gòu)詞法就是混合法breakfastlunch=brunch早午餐newsbroadcast→newscast新聞廣播televisionbroadcast→telecast電視播送smokeandfog→smog煙霧photoandgraphy→photography攝影，攝影術(shù)helicopterairport→heliport直升飛機(jī)場(chǎng)3.首字母縮略法TOEFL----TestofEnglishasaforeignlanguage托福IELTS---InternationalEnglishlanguagetestsystem雅思WHOWTONBAVOABBCCDUFOetc.Usetheappropriateformofthewordstofillintheblanks.用所給詞正確形式填空1.Themotherdidn’tknowwhyherdaughterwascrying_______.(noise)2.Hewasoneofthebest_______inyesterday’sfootballmatch.(play)3.Look!How______Kateislaughing!(happy)4.Itsnowed
