英语的“
be
”是个特殊动词;有些语言,如马来文等,并没有“
be
”这
样的动词。
“
Be
”除了原形的“
be
”之外,还有另外七种形式:
am, is, are, been,
being, was, were.
< br>在句子中,
“
be
”可以是系动
词或助动词
1
系动词,所构成的句子结构为主系表,表现形式有:
is,
am, are, was,
were
,在句子中翻译
为“是”
eg
:
I am a girl.
我是个女孩。
2
助动词,无实际意义,与其他动词一起构成时态。表现形式
有:
is, am, are, was, were
以及
p>
Be
原形。
eg
:
I am reading.
我正在看书。
(进行时)
例句对照
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)
eg
:
1. The man is a science
teacher.
这个男子是一位科学教师
2. Mary's new
dresses are
colourful.
玛丽的新衣服色彩鲜艳
3. I have been
there before.
我以前去过那里
4. My mother is
in the kitchen now.
母亲现在在厨房
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
eg
:
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
须借助
助动词“
do
”或“
don't
”之助
eg
:
9. Don't be silly!
10. Do be
obedient!
11.
Don't be a fool!
“
Be
”有两种缩写法,
eg
:
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:
eg
:
14. I'm not.
有人用“
ain't
”
,
但这并不是标准英语。
