be动词意思和用法:
一般的意思是:
是,此种用法,有多种变化形式,is,am,are,was,were,being,been,to be.
另外,be动词还有成为的意思。
根据句子中不同的人称、数和时态,应该选择相应的be动词。<?xml:namespace prefix = "o" ns = "urn:schemas-microsoft-com:office:office" />
要看句语的时态:
如果是一般过去时,就用was/were
如果是一般现在时,就用am/is/are
如果是一般将来时,就用will be
然后看主语的人称及复数形式:
一般过去时:
第一人称和第三人称的单数形式,则用was
第一人称和第二人称、第三人称的复数,则用were
一般现在时:
第一人称单数形式,用am
第三人称单数形式,用is
第一人称复数、第二人称、第三人称的复数形式,则用are
一般将来时:
will be
一般时态有关be动词的口诀:
我用am,你用are,is连接他/她/它,复数形式就用are
be动词的用法:
现在时 I am, you are, he is, we are, you are, they are
(缩略式 I'm, you're, he's, we're, you're, they're),
(否定缩略式 I'm not, isn't, aren't),
过去时 I was, you were, he was, we were, you were, they were
(过去时否定缩略式 wasn't, weren't),
过去分词been,现在分词being
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.
在句子中,“be”可以是主动词(The Principal Verb)或助动词(The Auxiliary Verb)
一、口诀:
我用am,你用are,is连着他,她,它;
单数名词用is,复数名词全用are;
变疑问,往前提,句末问号某丢弃;
变否定,更容易,be后莫忘记;
疑问否定任你变,句首大写莫迟疑。
二、Be动词在一般过去时中的变化:
1、am和is在一般过去时中变为was;
2、are在一般过去时中变为were
3、带有was或were的句子,其否定、疑问的变化和am is are一样,即否定句在was或were后加 not,一般疑问句把was或were调到句首。
