    I like shopping, but shopping with young children is not an easy thing. I have to look after them while I'm shopping. Shopping with my husband is not fun, either(也). I only go shopping with my husband when I need to buy something for him. If I look at a dress for myself, he says something like “The dress is too big” or “You don't need to buy that now”. I often go shopping with my friends. It's fun. I like shopping alone(单独) too.

    I like shopping very much, but I never go shopping at weekends. There are too many people in the shops. I don't like shopping with other people. It usually takes me a lot of time to choose things because I never buy the first things I see. I always look around other shops to find the best price. I'm good at finding the best deals(商品). I don't like buying food in small shops and street markets(市场). I think food in the supermarket is fresher and cheaper, so I shop there.
