分清词类的重要性

一、分清词类的意义要学好英语,第一件事就是分清词类。每种词类都有自己的特点,只有知道一个词属于哪种词类,才能正确地使用时还应弄清各个句子成分应由哪类词来担任。主语、宾语多由名词担当:Her admiration of the Brooklyn Doders—before the team moved to Los Angeles—was widely known.在布鲁克林的道奇队移师格杉矶之前.她对该球队的仰慕尽人皆知。谓语一股由动词担当:Lewis was admired for his word on medieval literature.刘易斯因其对中世纪文学的研究而受人仰慕。二、同一个词可作不同词类1.同一个词只用做一个词类的情况相对较少,多数词都可兼作不同词类。例:back可作名词、形容词、副词、动词:The cat wanted her back rubbed. 这只猫想让人给她挠背。(作名词)He used his influential friends to help him get into the civil service by the back door.他利用那些有权有势的朋友帮他走后门,到政府行政部门任职。(作形容词)The party expects to be back in power sfter the election.该党希望大选以后能重新攀权。(作副词)Who is backing the film? 谁是这部影片的赞助人?(作动词)2.off可用做形容词、副词、名词、介词:She sounded rather off on the phone. 她在电话中说话不太客气。(作形容词)How are you off for cash? 你有多少现款?(作副词)They 're ready for the off.他们己准备好起跑。(作名词)Scientist are still a long way off(finding)a cure.科学家还远末找到解决办法。(做介词)3.ruond可用做形容词、副词、介词、名词、动词:In round figures,the expected profit is about $100 million.以整数计,预期利润约为1亿美元。(作形容词)Please come in,let me show you round.请进来,我带你参观一下(作副词)The earth goes round the sun. 地球围普太阳转。(做介词)Life is a continual round the of parties for the roles in 'Friends'.对《老友记》的剧中人来说,生活就是一连串的聚会。(作名词)The Ferrari rounded the bend at top speed.那辆法拉利汽车以员高速度拐过弯迈。(作动词)
