1. As Teacher Death suggested, the best way to learn this is to read / read / read and to listen / listen / listen.
I do not know whether it is true, but some famous people have claimed that they learned English by watching English-
language movies every day for a year.
2. Personally, I like rules. And I congratulate you on wanting to know the rules for making questions.
3. Here are some thoughts (not answers):
a. Study your books very hard and understand the verb "to be" completely.
b. I hope that you understand that questions (and the negative) come from affirmative sentences.
i. Affirmative: Your country is beautiful. Question: Is your country beautiful?
c. You want some examples. I have made some up:
i. Your sentences are right. Are your sentences right? ("Right" is another word for "correct." In other words, your sentences are not wrong.)
ii. Mona is a good student. Is Mona a good student?
iii. It was cold yesterday. Was it cold yesterday?
iv. It is raining now in Los Angeles. Is it raining now in L.A.?
v. The children will be hungry tomorrow. Will the children be hungry tomorrow?
d. I hope that you are getting the idea. IF the verb is "to be," NEVER use "do" to start a question.
e. Yes, you are correct: "do" sometimes is a verb. But when it starts a sentence, it is used only to make a question.
f. Once you really understand how to make questions (and the negative) with "to be," then you are ready to move on to
other verbs. Those other verbs use "Do," "Does," and "Did" for questions. Here are some examples:
i. You speak English. DO you speak English?
ii. Your country has beautiful cities. DOES your country have beautiful cities?
iii. Tony went to Paris last year. DID Tony go to Paris last year?
g. In one post, it is impossible to explain what it takes a book to do. I hope that these thoughts may be of some help. I shall now write a few affirmative sentences. Would you please change them to questions?
i. Tom is a good student. ____________________?
ii. Airplanes fly very fast. ____________________?
iii. Your sentences are beautiful. ______________?
iv. Martha sees a movie every week. __________?
v. It was raining yesterday. __________________?
Answers: Do airplanes fly very fast? / Are your sentences beautiful? / Does Martha see a movie every week? / Was it raining yesterday?
If you have more questions, please ask. I think that it would be a good idea to start a new thread. Everyone here at usingenglish.com wants to help you. Please remember: You will learn it. It just takes time.
