洋洋：这是我新买的电子书阅读器，我刚下载了几本电子书。
心涛：这东西多少钱?
洋洋：一千多。
心涛：多少钱?
洋洋：一千多，不贵啊。
心涛：啊?一千多还不贵?这些钱够买多少本书啊!
洋洋：可是你知道吗，有了它，你可以看无数本书。
心涛：多少本?
洋洋：无数本!而且，你拎拎，它比一般的书轻吧。
心涛：确实挺轻的。
洋洋：所以你出差或者旅游的时候，可以把它带在身边，相当于带了一个小图书馆呢!
心涛：是啊!难怪这小小的东西这么贵!不过，我眼睛不好，这上面的字这么小，我看不清!
洋洋：你可以根据自己的喜好选择电子书的字体、大小、行距，也可以根据你的阅读习惯调整屏幕的亮度。
心涛：洋洋，要不你这个好东西先借我两天?
洋洋：我这是刚买的，我自己还没用呢!
X: What is this, Yang Yang?
Y: This is a e-reader I just bought and I just downloaded several e-books.
X: How much is this?
Y: About 1,000 Yuan.
X: How much?
Y: About 1,000. It's not expensive.
X: What? Isn't 1,000 expensive? How many books can 1,000 Yuan buy?
Y: But you know, with it you can read countless books.
X: How many?
Y: Countless! And try to take it. Isn't it lighter than usual books?
X: Indeed.
Y: So you can bring it when you travel or go on business. Just like bringing a small library with you.
X: Wow!No wonder it's so expensive. But my eyesight is not good. Characters here are so small. I can't see them clearly.
Y: You can choose font, size and spacing according to your like. And you can also adjust the lightening of the screen according to your reading habits.
X: Yang Yang, can you lent this to me for some days?
Y: I just bought it and what's more, I haven't use it yet.
