how to form a question tags?

Answer 1

To form question tags ..first you need to know what is question tag ? Question tags are an important part of everyday communication and perform many different functions. For example, they can be used to get a conversation started or keep it moving; they can soften an order to do something or they can be a more polite way to request information. Apart from the difficulty of knowing when to use question tags appropriately, the non-native speaker has to learn how to form them and how to say them. The general rule is that you finish a positive statement with a negative tag, and vice versa, using the main verb (if there is no auxiliary) or the first auxiliary verb (if there is an auxiliary). For example: It's a lovely day, isn't it? You've been told about the meeting, haven't you? ework, ... ...? I'm not late, ... ...? I'm invited to your party, ... ...?

Answer 2

Find the helping verb in the sentence.

If the helping verb is in negative form the question tag would be in positive form.
 *He didn't eat,did he?

If the helping verb is in positive form the question tag would be in negative form.
 *He did his homework,didn't he?

Never,seldom,rarely - tag in positive (does or do)

Now when no auxiliary verb is given the rules to follow are:
