(3) [be动词]be动词的用法以及规则
亲爱的楼主：be作助动词用的形式如下：①am,is,are,was,were②助动词+be：shall be,will be,can be,etc.③have/has/had + been（完成时）④am,is,…being（进行时） （1）表达进行时态句型 be + V-ing…（进行时态）例：What are you reading?（你正在阅读什么?）I am reading a magazine.（我正在阅读杂志.）例：He will be taking a walk in the park at this time tomorrow morning.（明天早晨此时他将会正在公园散步.）例：She has been teaching English in our school for years.（她已在我们学校教英语许多年了.）解说 第一例句是表达现在进行时,第二例句是将来进行时,第三例句是现在完成进行时.（2）表达被动语态句型 be +p.p.…（被动语态）例：English is spoken in both Canada and the United States.（加拿大和美国都讲英语.）例：Those keys were found in your drawer.（那些钥匙是在你的抽屉里找到的.）例：It can be done much faster in this way.（这件工作用这个方法可以更加快速地做好.） “Be”除了原形的“be”之外,还有另外七种形式：am,is,are,been,being,was,were.在句子中,“be”可以是主动词(The Principal Verb)或助动词(The Auxiliary Verb).当主动词时,“be”在性质上属于接系动词(The Linking Verb),后面要有名词、形容词、地方副词或短语作补足语(The Complement).例如：1.The man is a science teacher.2.Mary"s new dresses are colourful.3.I have been there before.4.Mother is in the kitchen now.这四个都是陈述句,可以变成疑问句,方法简单,把主语和“be”或助动词对换位置即可：5.Is the man a science teacher?6.Are Mary"s new dresses colourful?7.Have I been there before?8.Is mother in the kitchen now?当“be”要在祈使句中出现时,它必须借重助动词“do”或“don"t”之助,如：9.Don"t be silly!10.Do be obedient!11.Don"t be a fool!“Be”有两种缩写法,如下：12.He"s not./He isn"t.13.You"re not./You aren"t...但“am + not”的缩写法只有一个：14.I"m not.有人用“ain"t”,但这并不是标准英语.谈过了“be”作主动词的功能,现在看看“be”作助动词时,有些什么用法：1.“Be + 现在分词”以组成进行式时态(Continuous Tenses),如：15.Tony"s maid is washing his new car.16.The children are playing in the field.17.Samuel was eating when I came in.18.We have been living here since 1959.2.“Be + 过去分词”以组成被动语态(The Passive Voice),如：19.Her money in the drawer was stolen.20.A number of good jobs are taken up byforeigners.21.David studied in Taiwan but has been trained as a language lecturer in America.22.Can all the wonderful birds be found in our Bird Park?23.The disobedient boy was told to stand out- side the classroom.24.Steps are being taken to reduce traffic con- gestion during peak hours.25.Dishonest students will be immediately dealt with.
