結(jié)構(gòu)：

動詞原形 (第三人稱單數(shù)+s/es)。

第三人稱單數(shù)變化：

(1)直接在動詞詞尾加-s.

二、一般現(xiàn)在時用法

1. 表示經(jīng)常性，習(xí)慣性,永久性的動作或存在的狀態(tài)。

通常與副詞sometimes, often, usually, always, every day (year, month ), once (twice, three times) a day,等時間狀語連用。

三、一般現(xiàn)在時的句型轉(zhuǎn)換

(1)當(dāng)句子中有be動詞或情態(tài)動詞時，則把be動詞或情態(tài)動詞(can,could等等)提到主語的前面變成疑問句;在be動詞或情態(tài)動詞后面加not變成否定句.

例：

①陳述句：She is a student.

疑問句→ Is she a student?

否定句→ She is not a student.

②陳述句：I can swim.

疑問句→ Can you swim

否定句→ I can not swim.

(2) 當(dāng)句子中即沒有be動詞，也沒有情態(tài)動詞時，則在主語前加助動詞do (you,以及復(fù)數(shù)), does(單數(shù)she,he,it)變成問句;在主語后謂語動詞前加助動詞don’t(I,you,以及復(fù)數(shù)), doesn’t(單數(shù)she,he,it)變成否定句，助動詞后的動詞要變成動詞原形。

例：

①陳述句：We get up at 7:00 every morning.

疑問句→Do you get up at 7:00 every morning?

否定句→We don’t get up at 7:00 every morning.

②陳述句：She has a little brother.

疑問句→ Does she have a little brother?
