在英語中什麼時候要用be動詞(is,am,are)啊?
最好用例句來說明!


現在時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),過去時I was,you were,he was,we were,you were,they were(過去時否定縮略式wasn't,weren't),過去分詞been,現在分詞being英語的“be”是個特別動詞;有些語言,“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”可以是主動詞(The Principal Verb)或助動詞(The Auxiliary Verb).【當主動詞時,“be”在性質上屬於接系動詞(The Linking Verb),後面要有名詞、形容詞、地方副詞或短語作補足語(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.【這四個都是陳述句,可以變成疑問句,方法簡單,把主語和“be”或助動詞對換位置即可: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“be”要在祈使句中出現時,它必須借重助動詞“do”或“don't”之助,如:9.Don't be silly!10.Do be obedient!11.Don't be a fool!【“Be”有兩種縮寫法,如下:12.He's not./He isn't.13.You're not./You aren't…【但“am + not”的縮寫法只有一個:14.I'm not.有人用“ain't”,但這並不是標準英語.談過了“be”作主動詞的功能,現在看看“be”作助動詞時,有些什麼用法:【1.】“Be +現在分詞”以組成進行式時態(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 +過去分詞”以組成被動語態(The Passive Voice),如:19.Her money inthe 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 peakhours.25.Dishonest students will be immediately dealt with.
