現(xiàn)在時(shí) I am,you are,he is,we are,you are,they are （縮略式 I'm,you're,he's,we're,you're,they're）,（否定縮略式 I'm not,isn't,aren't）,過(guò)去時(shí) I was,you were,he was,we were,you were,they were （過(guò)去時(shí)否定縮略式 wasn't,weren't）,過(guò)去分詞 been,現(xiàn)在分詞 being 英語(yǔ)的“be”是個(gè)特別動(dòng)詞；有些語(yǔ)言,“Be”除了原形的“be”之外,還有另外七種形式：am,is,are,been,being,was,were.在句子中,“be”可以是主動(dòng)詞(The Principal Verb)或助動(dòng)詞(The Auxiliary Verb).【當(dāng)主動(dòng)詞時(shí),“be”在性質(zhì)上屬于接系動(dòng)詞(The Linking Verb),后面要有名詞、形容詞、地方副詞或短語(yǔ)作補(bǔ)足語(yǔ)(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.【這四個(gè)都是陳述句,可以變成疑問(wèn)句,方法簡(jiǎn)單,把主語(yǔ)和“be”或助動(dòng)詞對(duì)換位置即可：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?【當(dāng)“be”要在祈使句中出現(xiàn)時(shí),它必須借重助動(dòng)詞“do”或“don't”之助,如：9.Don't be silly!10.Do be obedient!11.Don't be a fool!【“Be”有兩種縮寫(xiě)法,如下：12.He's not./He isn't.13.You're not./You aren't...【但“am + not”的縮寫(xiě)法只有一個(gè)：14.I'm not.有人用“ain't”,但這并不是標(biāo)準(zhǔn)英語(yǔ).談過(guò)了“be”作主動(dòng)詞的功能,現(xiàn)在看看“be”作助動(dòng)詞時(shí),有些什么用法：【1.】“Be + 現(xiàn)在分詞”以組成進(jìn)行式時(shí)態(tài)(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 + 過(guò)去分詞”以組成被動(dòng)語(yǔ)態(tài)(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.
