II語法填空（共10小題，每題2分，共20分）
仔細(xì)閱讀下面短文，短文中有10個空格。請按照語境以及括號里的具體要求完成語法填空、詞形變化等。答案填寫在答題卡標(biāo)號為26—35的對應(yīng)位置。
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 26   media that offer a lot more 27  (colour) 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 book is a wonderful collection 28       words 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 29  it is from the TV or the Internet.
But an even more important point is 30   books give you something that modern media simply can not: The webpage is always full of pictures and the text is often designed to make it as easy to read as possible.
Though “easy” may be welcome, 31 (luck) 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 32  (choose) what you read and doing it by yourself 33  (mean) that it’s something you do by and for yourself. You can choose what you want to read. It’s hard work,34   while you are reading, you’ll find that what once 35  (seem) like a duty is now a pleasure.
