小学英语一般现在时(一)知识点及练习题
展开本次知识点归纳:
表达经常性或习惯性的动作、状态、表示真理或客观事实。
二、重要知识点提示:
一般现在时需要表示经常性的时间状语例如:always、usually、ften、smetimes、everyday、in the mrning/afternn/evening
、n Sundays等。
be动词的一般现在时有三种形式,即:am, is, are(翻译为“是”)
1. 如果主语是第一人称I(我)时,be动词用am。如:I am a student.
I am 还可缩写成I'm am 与 nt 不能缩写。
2. 如果主语是yu (你,你们), they (他们,它们,她们)或名词复数 (两个以上的人或物)时,be动词必须用are
如:Are yu twelve?
are与主语还可缩写。如: We're, They're, Yu're。
而are与 nt可缩写成aren't
3. 如果主语是单数名词、不可数名词或第三人称单数代词(he, she, it)时,be动词用is。
如:My mther is a teacher.
is也可与主语缩写,如: He's, My mther is = My mther's等。但是This is不可缩写。而is与nt可缩写成 isn't
4. 句中含有be动词的陈述句变一般疑问句。
把be动词提到句首,be动词要变大写。注意第一人称变第二人称。回答时用yes或n表示,结构:Yes, 主语+be动词,N,主语+be动词+nt。
5. 句中含有be动词的肯定陈述句变否定句。
先找肯定陈述句中的be动词,在be动词后加nt.
根据以上叙述我们可以把动词的用法以口诀的形式表述出来:
我用am,你用are, is跟着他(he),她(she),它(it);
单数名词用is,复数名词全用are。变疑问,往前提,句末问号莫丢弃。变否定,更容易, be后nt莫忘记。
疑问否定任你变,句首大写莫迟疑。
There be句型w W w .
There be 的固定句型:There be + 某物/某人 + 介词 + 某地
表示:在某地有某物(或人)
2、在there be 句型中,主语是单数,be 动词用is ;
主语是复数,be 动词用are ; 如有几件物品,be 动词根据最靠近be 动词的那个名词决定。
3、there be 句型的否定句在be 动词后加nt , 一般疑问句把be 动词调到句首。
4、there be句型与have(has) 的区别:
there be 表示在某地有某物(或人)have(has) 表示某人拥有某物
