  说话人1 Hi. I wish to buy some cheese for a barbecue this weekend.(Q8)
  说话人2 What kind would you like?
  说话人1 Sorry, I don't know much about cheese. What type do you think would be suitable for a barbecue?
  说话人2 That's easy for a barbecue. Could have any cheese you want. I imagine there will be different foods, and people will just help themselves and eat at their own pace, right? Exactly.
  说话人1 It will be very casual. We will just be a small group of friends gathering together at washington park. There will be around 20 of us, including children. Great.
  说话人2 So you could have different types of cheese. How much would you like to spend?
  说话人1 Not very much, let's say, $30.
  说话人2 I would suggest having at least one soft cheese and one hard cheese that will offer you a good variety to suit different people's tastes.(Q9)
  说话人1 That sounds good. What's the difference between a soft cheese and a hard cheese?
  说话人2 It depends. But generally speaking, soft cheeses are creamy and go well with sw
eet things like honey and jam. I would suggest something like this, spanish goat cheese, only $15, a very good price. You can spread it on bread with a knife.(Q10) And then at a tiny bit of honey on top, it's delicious. Children love it.
