1. be動詞的6種基本用法
be動詞的用法
英語的“be”是個特別動詞;
“Be”除了原形的“be”之外,還有另外七種形式:7a686964616fe58685e5aeb931333332633063am, 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”在性質上屬于接系動詞(The Linking Verb), 后面要有名詞、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”, 但這并不是標準英語。
談過了“be”作主動詞的功能,現在看看“be”作助動詞時,有些什么用法:
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 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.
2. 有關be動詞的句型
be動詞的一般現在時有三種形式,即:am, is, are。 1. 如果主語是第一人稱I(我)時,be動詞用am。如:I am a student. 我是一名學生。 I am 還可縮寫成I'm。如: I'm David. 我是大衛。 2. 如果主語是you (你,你們), they (他們,它們,她們)或名詞復數 (兩個以上的人或物)時,be動詞必須用are。如:Are you twelve? 你是十二歲嗎? Tom and Lily are good friends. 湯姆和莉莉是好朋友。 They are at school. 他們在學校。 are與主語還可縮寫。如: We are= We're, They are =They're, You are = You're。而are與 not可縮寫成aren't。如:They aren't students. 他們不是學生。但是am與not不能縮寫。 3. 如果主語是單數名詞、不可數名詞或單數第三人稱代詞(he, she, it)時,be動詞用is。如:My mother is a teacher. 我的媽媽是一名老師。 He is a student. 他是一名學生。 is也可與主語縮寫,如: He is = He's, My mother is = My mother's等。但是This is不可縮寫。而is與not可縮寫成 isn't。如:This isn't a book. 這不是一本書。根據以上敘述我們可以把動詞的用法以口訣的形式表述出來:我(I)是am, 你(you)是are, 剩下is留給她(she), 他(he), 它(it), 兩個以上都用are。 [思路分析] be作助動詞用的形式如下: ①am, is, are, was, were ②助動詞+be:shall be, will be, can be, etc. ③have/has/had + been(完成時) ④am, is, …being(進行時) [解題過程] (1)表達進行時態句型 be + V-ing…(進行時態)例:What are you reading? (你正在閱讀什么?) I am reading a magazine. (我正在閱讀雜志。)例:He will be taking a walk in the park at this time tomorrow morning. (明天早晨此時他將會正在公園散步。)例:She has been teaching English in our school for years. (她已在我們學校教英語許多年了。)解說 第一例句是表達現在進行時,第二例句是將來進行時,第三例句是現在完成進行時。(2)表達被動語態句型 be +p.p. …(被動語態)例:English is spoken in both Canada and the United States. (加拿大和美國都講英語。)例:Those keys were found in your drawer. (那些鑰匙是在你的抽屜里找到的。)例:It can be done much faster in this way. (這件工作用這個方法可以更加快速地做好。)
