小学英语肯定句、否定句、一般疑问句和特殊疑问句的详解

小学英语肯定句、否定句、一般疑问句和特殊疑问句的详解

一、be动词：am, is, are

二、肯定句、否定句、一般疑问句和特殊疑问句定义

1．肯定句：表示肯定的意思, 即不含有否定词“不”。

比如：我是一个学生 I am a student.

他去上学 He goes to school.

2．否定句：表示否定的意思。

比如：我不是一个男孩。 I am not a boy

他不去上学 He does not go to school.

3. 一般疑问句：回答为“是yes”或者“否no”的问句。

比如：你是一个学生吗？ Are you a student?

你喜欢英语吗？ Do you like English?

4. 特殊疑问句：回答不是“是yes”或者“否no”的问句，根据提问内容具体回答。

比如：现在几点了？ What’s the time?

哪一支笔是你的？ Which is your pen?

肯定句变否定句：在am, is, are can后面加上not,其余按顺序照抄。

肯定句变一般疑问句：把am, is, are can提前放到句首并大写Am, Is, Are,其余照抄。特别注意有I We 改为YOU,Are you 问 Iam 或we are 答

Are you a teacher? Yes,I am. Are you students? Yes,we are.

2.

非单三时用do, 单三时用does

肯定句：I like English.

否定句：

单三肯定句：He likes English.

like English?

否定句：like English.

3.动词过去式的句子分两类，was\were 和动词过去式

有 was,were 改为否定句，直接在后面加 not ，改为一般疑问句把 was were 直接提前，有 I we 改为 you

I was a teacher.

I was not a teacher.

Were you a teacher?

Yes,I was.

有动词过去式，改为否定句加didn’t ，过去式还原。改为一般疑问句，句前加Did ，过去式回原

I watched TV last night.

I didn’t watch TV last night.

Did you wactch TV last night?

Yes,I did.

特殊：1.some变为any。如：

There are some birds in the tree.→There aren't any birds in the tree.

但是，若在表示请邀请、请求的句子中，some可以不变。如：

Would you like some orange juice?

与此相关的一些不定代词如something, somebody等也要进行相应变化。
