It is sunny today.變一般疑問句:

Is it sunny today?

肯定句變一般疑問句:

1. 原句中含有be動詞（am, is, are, was, were）：

He is a teacher.

-Is he a teacher?

There were many students in the classroom.

-Were there many students in the classroom?

2. 原句中含有助動詞have（has, had）

I have pronounced your name correctly.

-Have I pronounced your name correctly?

He has got a girlfriend.

-Has he got a girlfriend?

3.原句中含有情態動詞

They will go to the aquarium if it is fine tomorrow.

-Will they go to the aquarium if it is fine tomorrow?

She could only raise her hand in a gesture of benediction.

-Could she only raise her hand in a gesture of benediction?

4. 句中第一個動詞是原形時，在主語前加上do。

I get to school at six o'clock every day.

-Do you get to school at six o'clock every day?

5. 句中第一個動詞是三單形式時，在主語前加上 does，原來的動詞三單形式改為動詞原形。

He teaches English.

-Does he teach English?

6.句中第一個動詞是過去式時，在主語前加上 did，原來的動詞過去式改為動詞原形。

The children had a good time in the park last night.

-Did the children have a good time in the park last night?

It is sunny today.這個句子的意思是:今天天氣晴朗。該句是一般現在時態，句中的謂語動詞是be動詞is, 所以變一般疑問句的時侯，應該把謂語be動詞is提前，再把首字母大寫，然後句末用問號，所以這道題的答案是:Is it sunny today？今天天氣晴朗嗎？
