A: Hey guys .I intend to buy a new cell phone because the one I used now is out of fashion. Would you give me some advice? B: Yeah, I suppose that the Nokia Lumia 1020 would be a great choice because it has a 41 million pixels（像素） digital camera. Its awesome.A: Fascinating. But I dont like windows phone. It is a new system and cant support many applications. Its really inconvenient.C: Umm, thats right. How about Iphone5. Last month I bought one.A: Really? How do you feel about it?C: Oh, I love this phone. Its really nice. You know, it has a quite cool appearance. Also the function is much more powerful than other cell phone. Whats more, Apple is a international well-known brand, so believe me, this phone is really worth buying.A: Sounds interesting. How much is it.C: Its about 5000 Yuan.A: Oh, god. It is too expensive. Im running short of money. I dont think I can afford it.D: Why dont you try the Mi 3 .It is more suitable for you.A: Well I was preparing to buy Mi 3 at first. It seems like a domestic phone (国产手机) with high cost performance（高性价比） but actually it has lots of drawbacks such as poor heat dissipation（散热） and high power consuming.D: You can buy the Mi 4, it is much better than Mi 3. The price is still reasonable and it is popular with young people.A: Thank you, but I still think I should take more consideration.C: Are you interested in Samsung?A: Samsungs shell is made of plastics. It is fragile and stained（弄脏） easily. Besides, it looks ugly. I prefer to buy the domestic at the same price.B: Well, it is not easy to choose a suitable phone. So what kind of smart phone do you want to buy?A: Firstly the appearance must be beautiful. And then, I love taking photos especially selfie（自拍）, so the photography function must be good. D: I see, maybe you could try the OPPO find 7. The photo is really clear despite at night.A: Wow, its fabulous. How much is it. D: Nearly 3400 Yuan. May be a little expensive. But you should know that Oppo Find 7s body is thin and light so it is easy to carry and the screen is larger than before, reaching 5.5 inch. It is worth mentioning that the battery life could be extended. Its really a high-quality product.A: Good. And the price is reasonable. Ill take it. B: Wait. I also want to change my phone. Can you give me some suggestion?C: No problem. But the first question is always, “What is your budget”B: Anyway, My request is really not high. Im just crazy about music. Id like to choose some with excellent sound.C: I would like to recommend Sony. Sony Corporation（索尼公司） always does well in this aspect and you just need to pay 2000 Yuan. It is good value for price.B: So great. Im going to buy the new smart phone this weekendA: Im coming with you.
