講義：

一般現(xiàn)在時

一、be動詞的一般現(xiàn)在時

1.be動詞的一般現(xiàn)在時常用來討論客觀存在的事實或狀態(tài)，其肯定形式有am,is, are三種。其中am用于第一人稱I；is用于第三人稱單數(shù)形式he, she, it及其他單數(shù)名詞；are用于第二人稱you、復數(shù)人稱we, you, they及可數(shù)名詞復數(shù)或并列名詞做主語時。可進行縮寫。

例：I am Gina. =I'm Gina.

He is Brown. =He's Brown.

They are Jane and Linda. =They're Jane and Linda.

2. be動詞的否定式是在be后面加not。（表格為一般現(xiàn)在時態(tài)中，be動詞的否定形式）

3.be動詞的一般疑問句的結構為：be(am/is/are)+主語+……？

肯定回答為：Yes, 主語+be(am/is/are).

否定回答為：No, 主語+be(am/is/are)+not.

例：-Are they your classmates?

-Yes, they are. / No, they aren't/are not.

注意：第一人稱I變一般疑問句時，需轉換成第二人稱you。

二、實意動詞的一般現(xiàn)在時

1.肯定形式：

當句子的主語是第三人稱單數(shù)形式時，謂語動詞也要用第三人稱單數(shù)形式。其變化規(guī)律如下：

例：He gets up at six every day.

2.否定形式：

3.一般疑問及回答：
