1 Can you cook?

Well, I can, but to be honest with you, I'm not really all that good at it, the main reason being that when I was younger, my mum used to do pretty much all the cooking, and I never paid that much attention to how she was doing it. So right now, I guess you could probably count the number of dishes I can cook on one hand. 

(这里故意在说原因的时候说小时候的原因。以此带出过去式的两种形式，was, used to 以及过去进行时was doing it)

2 Why do people have pets?

Well, I suppose there are a handful of reasons, one of which would be that pets keep people company, and as a pet owner myself, I know that they are really good at cheering you up if you're feeling a little down. So they make great companions. 

(这里混合了现在时态和现在进行时哦)

3 Have you ever painted before?

Yeah, for sure I have! But if truth be told, the last time I painted anything was absolutely ages ago! I mean, I seem to remeber doing quite a lot of painting when I was at kindergarten and primary school, but since then, I'd say I've done pretty much no painting at all. 

(这里混合了现在时，过去时，现在完成时，大家面对have you ever done 这种题的时候可以说上一次做这件事是什么时候，这样可以起码带出过去式)

4 Do you spend lots of time watching films?

I spend a fair amount of time watching them, yeah, because there have beenquite a few good movies which have come out in the past few years. But I'm now trying to limit myself to watching just a few hours a week so that it doesn't take up too much of my time. 

(现在时。现在完成时，现在进行时的混合，大家常常可以在名词后面加个which/that 从句，然后从句中带出时态)
