Read the listening materials and check your answers.
Li Na: Hi, Liu Wei. I'm looking at some reviews of laptops. I need to buy a
new one.
Liu Wei: Maybe I can help you. What do you usually use the laptop for
Li Na: I mainly use it to do my homework, such as searching for information
for my project, doing my online homework. And I also use it to draw
pictures. You know, I love using drawing software!
Liu Wei: I see. In that case, I think you need a fast computer with a good touch
screen. Maybe you should look at the Lightning X. It has a touch screen
and comes in different sizes.
Li Na: That sounds good.
Liu Wei: The 13-inch model weighs 1.5 kg and has 8 GB of memory. The
price is good too. It’s only 4,998.
Li Na: Oh, 4,998 That’s not bad, and 1.5 kg is light, but 8 GB perhaps is
not enough memory.
Liu Wei: How about the Spec 15 It's a bit heavier at 2 kg, but the screen is
15 inches and it has 32 GB of memory.
Li Na: How much does it cost
Liu Wei: It's a bit more expensive: it costs 8,600. What about theAl0l
There are two models. The 14-inch and the 17-inch. The 14-inch
weighs 2 kg and the 17-inch is 2.5 kg.
Li Na: But 2.5 kg is too heavy. Can you tell me about the 14-inch
Liu Wei: Sure. It has 32 GB of memory and costs just 7,500. It’s the
latest model. One special feature is its amazing touch screen. It’s
definitely good for drawing.
Li Na: Wow! That’s good.
