The widespread number of food scandals(丑闻)in  China is making many people pause before they put their chopsticks in their mouths．They are wondering if the food they are eating is clean，healthy and nutritious(营养) or does it contain（包含） something harmful that will cause disease?
Most of the food we eat today is processed food(加工食品)．That means the foods we buy in stores and supermarkets，especially packaged foods，are prepared in factories．Chemicals are added to the foods in these factories to  make them look better，taste better and last longer on the shelf．The chemicals are supposed to be harmless and there are laws that regulate(控制) which chemicals can and cannot be used．Unfortunately，some producers do not obey the laws．
A producer of steamed buns(馒头)in Zhejiang Province was recently discovered to be breaking the law．He was adding yellow dye and other banned chemicals to the buns．He was also taking old buns and using them to make new buns．Most of the buns were sold to schools and eaten by students…like you!

Do not waste time in learning the word list. It is not a good way to remember new words. The best way to learn new words is through listening. You can find radio programmes or TV programmes. And listen to them carefully. When you listen to the conversations, you will learn the pronunciation easily. Of course, it is not enough; you have to remember their spellings.
Some people find that they can learn the names of everyday objects such as box, bottle, cup, desk and so on, in the following way. They write the names of things on paper, and then they read the words on the paper. Try this and see if this way works for you. If it does not work, then go on to practise listening to the conversations.
