We recycle(回收利用）rubbish, so why not language? Recycling language means using vocabulary that you have learnt before again and again. However, unlike rubbish that piles up(堆積)in our environment. if we do not recycle language, we simply forget it. So how do you recycle language?
There are basically three ways to do it. The first 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. 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 favourite 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 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 chat with yourself about your favourite articles at home. You can pretend there is someone with you who speaks English and tell him what you are thinking about or how you feel.
(     )12. According to the passage, recycling language means ______.
A. repeating vocabulary at times    B. revising vocabulary at a proper time
C. learning new vocabulary as much as possible
D. using vocabulary that we have learnt very often
(     )13. If we recycle language, it may ______.
A. be kept in our mind                   B. be forgotten easily
C. pile up in our environment            D. disappear from our mind soon
(     )14. Which of the following is NOT mentioned in recycling language?
A. Reading.        B. Listening.       C. Writing.        D. Speaking.
(     )15. Which of the following is probably the best title of the passage?
A. Why to Recycle Language              B. How to Learn Vocabulary
C. How to Recycle Language              D. Why to Learn Vocabulary

Chinese government has decided to give up the rules of food with no checking .According to the Xinhua News, from September 17th , 2008, Chinese government decided to give up the rules of food with no checking. Many people said yes to it. The officer said that these days, the food safety accident about children milk of Sanlu made the government decide to give it up. In order to keep the food safe and people healthy, Chinese government said that all the food must be checked. The rule of food with no checking made in 1999 was given up from that day.

It gives them the chance of making the food of poor quality,” an old man said in the shop. “ I hope our government not only gives it up, but also makes some strong rules to manage the companies,” a young woman told us. “ The important point is our government should send officers to the companies and check their food every time,” a shop owner said. A young expert of food safety said, “ The department of government should take the food from the shop or supermarket and check, not ask them to send. In that way, we can get the real checking.”
