句型转换是小学英语里难度偏高的题型，很考验孩子英语综合功底。除了积累单词，还得熟练掌握语法规则、理清句子语序。不少孩子在这类题目上容易丢分，核心原因就是没有掌握对应的解题思路。

01 肯定句改为否定句步骤

1. 句子带有 be 动词，直接在 be 动词后面加上 not，常见形式：is not、are not、am not。
2. 句子含有 can、should、will 这类情态动词，就在情态动词后加 not。 例：can not，should not，will not。
3. 如果句子里既没有 be 动词，也没有情态动词，就要在实义动词前面加上对应的否定助动词 don’t /doesn’t /didn’t。
4. 句中的 some 一般要换成 any。

例句： I am a girl. → I am not a girl. You are a student. → You are not a student. → You aren’t a student. This is Tom’s bag. → This is not Tom’s bag. → This isn’t Tom’s bag.

02 肯定句改为一般疑问句步骤

1. 有 be 动词，把 be 动词调到句首，剩下内容原样抄写；同时注意 some 改为 any，I 改为 you，my 改为 your，末尾句号改成问号。
2. 有 can、shall、will 这类情态动词，把情态动词放到句首，其余内容照抄，同样要变换 some/any、I/you、my/your，标点换成问号。
3. 没有 be 动词、情态动词时，在句首加上助动词 Do / Does / Did，后面内容照抄，同步调整上面提到的代词和 some，结尾改为问号。

⚠️ 注意：句子首字母必须大写，句末使用问号。

例句： I am in Class 6. → Are you in Class 6? You are from America. → Are you from America? It is an orange. → Is it an orange?

✅ 一般疑问句回答方式 分为肯定回答和否定回答，肯定用 yes 开头，否定用 no 开头。 结构：Yes + 主语 + am/is/are/was/were/can/do/does/did. No + 主语 + am not /isn’t /aren’t…

例句： —Are you an English teacher? —Yes, I am. / No, I am not. —Is that a bird? —Yes, it is. / No, it isn’t.

03 对划线部分提问

对划线部分提问是小学英语的一大难点，只要抓住固定步骤，做题就会轻松很多。 解题四步法： 一代：选用合适的疑问词替换划线部分 二移：将疑问词放到句子最前面 三倒：调整主语和谓语顺序（如果划线部分本身是主语或者主语的修饰词，语序不用改动）；some 变 any、I 变 you、my 变 your 四抄：把句子剩下的内容照抄下来

疑问词要根据划线内容来选择，小学高频用法如下： ① 划线内容是事物、事情 → what This is a book. → What is this? I often play football on Saturdays. → What do you often do on Saturdays?

② 划线内容是人 → who He is my brother. → Who is he?

③ 划线内容是地点 → where The box is on the desk. → Where is the box?

④ 划线内容是时间点 / 时间段 → what time（几点）、when（什么时候） It's seven twenty. → What time is it? I usually get up at six. → When do you usually get up?

⑤ 划线内容是年龄 → how old I am twelve. → How old are you? My father is thirty-three. → How old is your father?

⑥ 划线内容是职业 → what Mike is a worker. → What is Mike?

⑦ 划线内容是颜色 → what colour My hat is blue. → What colour is your hat?

⑧ 划线内容是数量：可数名词用 how many；不可数名词用 how much I can see five kites. → How many kites can you see? There is some milk in the glass. → How much milk is there in the glass?

⑨ 划线内容是价格 → how much This pen is nine yuan. → How much is this pen?

⑩ 划线内容是物主代词 → whose That is my book. → Whose book is that? The bag is yours. → Whose is the bag?
