陳述句是用來(lái)說(shuō)明一個(gè)事實(shí)或表明說(shuō)話人的看法。陳述句的末尾用句號(hào),朗讀時(shí)一般用降調(diào)。陳述句分為肯定句式和否定句式。陳述句要用正常語(yǔ)序。

由肯定句變否定句的方法
1.找原句的動(dòng)詞。若動(dòng)詞為等,直接在動(dòng)詞后加am ,is ,are ,can ,must ,will 等,直接在動(dòng)詞后加not 變否定。若動(dòng)詞為want ,like 等實(shí)義動(dòng)詞,要借助助動(dòng)詞don't 或doesn't 放在原句動(dòng)詞之前變否定句(原句動(dòng)詞為單三形式用doesn't ,其他形式用don't )。
2.原句其他單詞位置不變。
I am a teacher. I am not a teacher. 我是一名教師。我不是一名教師。
Mary likes apples. Mary doesn't like apples. 瑪麗喜歡蘋(píng)果?,旣惒幌矚g蘋(píng)果。
have在表示“有”時(shí),其否定形式有兩種,一種是在后面加not,一種是利用do的形式。
I haven't any time to play football.
I don't have any spare time to play football.
我沒(méi)有時(shí)間踢足球。
