陳述句

說(shuō)明事實(shí)或陳述說(shuō)話(huà)人觀點(diǎn)的句子。

1、基本結(jié)構(gòu)：主語(yǔ)＋謂語(yǔ)＋賓語(yǔ)

或者：主語(yǔ) 系動(dòng)詞 表語(yǔ)

主語(yǔ)＋謂語(yǔ)＋賓語(yǔ)：主語(yǔ)是名詞性的詞，謂語(yǔ)是動(dòng)詞或動(dòng)詞短語(yǔ)，賓語(yǔ)是動(dòng)作的承受者或解釋謂語(yǔ)的結(jié)果。 e.g.  He doesn’t read books.

主語(yǔ) 系動(dòng)詞 表語(yǔ)：主語(yǔ)是名詞性的詞，系動(dòng)詞就是be動(dòng)詞，表語(yǔ)則用來(lái)表示主語(yǔ)的狀態(tài)、樣子等等。e.g. The sun is the most important planet in the galaxy.

2、陳述句有肯定形式和否定形式兩種：

1）肯定陳述句  We all like pandas very much.

2）否定陳述句  He doesn’t do homework at weekends

3、肯定陳述句改否定陳述句，變換方式主要有兩種：

①一般是在be動(dòng)詞或情態(tài)動(dòng)詞后加not。

Mary was at school yesterday. —> Mary was not at school yesterday.

I can make a model plane. —>I can not make a model plane.

②不含be動(dòng)詞或情態(tài)動(dòng)詞的，行為動(dòng)詞前要用助動(dòng)詞的否定式（don’t，doesn’t，didn’t），后面跟動(dòng)詞的原形。

He likes drawing pictures.—>He doesn’t like drawing pictures.

I went to the park yesterday. —>I didn’t go to the park yesterday.
