完形填空

In this article I'd like to tell you how to behave better in an IELTS oral English test. Everyone will make necessary preparations for some possible topics in order to increase your performance in the interview.  小题1: What would you do if you were asked in an interview to talk about how you feel about your hometown if in fact you really dislike living there?

Some people might think that being truthful in this situation and giving a negative answer, they would not do the right thing.  小题2: They talk about how they love living there and give a positive answer which sounds more attractive.

 小题3: And giving a negative opinion of something is not important, either.  小题4: If you have more to say by being truthful, even if it is to express a negative opinion, then that is what you should talk about.

 小题5: And follow it up with your reasons for disliking it instead of saying “I like my hometown…” and then struggle to find something to say.

We should consider how to deal with this situation in the best way

A. However, sometimes, you will be asked to talk about something that you don’t really like or don’t really want to talk about.
