Jane：Hi, welcome to Hal’s Computer World. [ ] Smith：I would like to buy a computer for my son. I was told it is cheaper to buy computers here. Do you have any recommendations？ Jane：Yes. We have plenty of choices for you. So, home computer or a laptop, which one does he like？[ ] Smith：He prefers ASUS(华硕), laptop, which is much more convenient. Jane：I see. [ ] ASUS F83E335Cr-SL. It is really suitable for students. Smith：Let me see. Well, it’s good but I don’t think 320 GB is enough. Jane：If you wish to upgrade the hard drive, we can definitely do so. It costs 150 to upgrade it from 320GB to 500GB. Smith：Great. My son likes keeping a lot of movies and pictures on the hard drive. Jane：No problem. I’ll give you a more detailed brochure later. Smith：Thank you. [ ] May I have a discount？ Jane：In total it costs 3900 yuan. If you pay for it on Saturday or Sunday this week, you can actually get 5 percent off the usual sale price. Smith：Wow. That’s really good. [ ]
