阅读短文,按要求完成短文后的各项任务。

The holiday’s upon us.After months of study, you have some time to yourself.So, why not read a book? Well, some people will say, “Why trouble with books? We have the Internet and other media(媒体)that offer a lot more colorful programs.Books are history!”

But don’t be fooled.There’s still a lot to be said for reading-and reading as widely as possible.

One clear reason is that a well-chosen _________is a wonderful collection of _______ and expressions, so long as you have a good dictionary, of course.Believe me, it’s far easier to get new English words and expressions from a book or article than it is from the TV or the Internet.

But an even more important point is that books give you something that modern media simply can not. The webpage(网页)is always full of pictures and the text is often designed(设计) to make it as easy to read as possible.Though “easy” may be welcome, unluckily it’s of little use for any long-time development of reading skills and the general language level.For that, there’s still no substitute(替代品)for a book.

But perhaps the best single reason is that simply choosing what you read and doing it by yourself means that it’s something you do by and for yourself.You can choose what you want to read.It’s hard work, but while you are reading, you’ll find that what once seemed like a duty is now a pleasure.Reading can bring us great pleasure.
