“I am a teacher” 变成一般疑问句怎么改？
Are you a teacher？
英语句子改为一般疑问句的方法：
1 含有be动词的句子,把be动词提前.(be动词是：is\am\are)
例如：
There are some birds in the tree.Are there any birds in the tree?
She is having dinner.Is she having dinner?
2 含有助动词have、has或者had的句子,把have、has或者had提前.
例如：
I have got some oranges.Have you got any oranges?
Yes,I have.No,I haven’t.
He has gone to Paris.Has he gone to Paris?
3 不含be动词也没有助动词的句子,加助动词do、does或did并把do、does或did提前.
例如：
I like cakes very much.Do you like cakes?Yes,I do.No,I don’t.
He lives in the building near the hospital.Does he live in the building near the hospital?
Yes,he does.No,he doesn’t.
4 含有情态动词的句子,把情态动词提前.
例如：
I can run fast.Can you run fast?Yes,I can.No,I can’t.
I’d like some coffee.Would you like some coffee?
注意：
1 把陈述句改为一般疑问句时,要特别注意在需要的地方改变人称.
2 把陈述句该为一般疑问句时,如果句中有some,要把some改为any.但是在表示请求的句子中,却不要做这种改动,因为这表示问话的人希望得到一个肯定的答复.
3 把陈述句改为一般疑问句时,不要改动时态.
4 把陈述句改为一般疑问句时,如果句中有do或have以及其相关形式,要注意看do和have是否助动词,如果是实意动词则需要再加适合的助动词.
