2．閱讀下面短文，然后根據(jù)內(nèi)容選擇個最佳答案。
We recycle garbage，so why not language？Recycling language means using vocabulary（單詞）that you have learnt before again and again.But unlike garbage that piles up（堆積）in our environment，if we do not recycle language，we will forget it.So how do you recycle language？There are about three ways to do it.
The first way is through reading.Go back to your favourite articles and read them once more.Just reread them and do not worry about each vocabulary item（單詞）.If there are some that you are not sure about，make a guess and you will probably guess right.
The second way to recycle is through writing.Look at some of your favorite articles and write either a short paragraph or a few sentences in your own words.After you have done this a few times ，go back and read through what you have written，checking（檢查）vocabulary functions.Don't worry if you have made mistakes.That's how you learn.
The third way to recycle language is by having an imaginary talk with yourself about your favorite articles at home.You can pretend（假裝）there is someone with you who speaks the same language and tell him what you are thinking about or how you feel.
