Many people have heard stories of the California gold rush during the 19th century, when lots of people went there in search for gold. Panning (淘洗) for gold has a rich and interesting history. Nowadays some people continue to pan for gold in California. Although it cannot be regarded as a method for earning income, taking on gold-panning as a hobby can give you a feeling of being in the old west and get you out into nature.
The only tool that is required to pan for gold is a gold pan. You can use a regular old flat pan, but “officially” gold pans are quite cheap so you may as well buy one that is made for the task. Most sold pans come in either plastic or medal.
Once you have your pan you will want to start practicing your gold panning technique. Panning for gold works because gold is much heavier than most rocks. To pan for gold you add rock and dirt form the bottom of a stream to your pan and then gently let water flow through the pan. The lighter-weight rocks are slowly swept away while any gold will be left behind in the pan.
To start panning for gold, first you will need to find a good location. Try checking maps of your area and old history books to find location where there were gold mines in the past. Even though most of the gold have already been removed, there are likely to be small leftovers that you can find. Once you have found an area that looks promising, look for any small stream or river where you can try out panning for gold.
Panning for gold requires patience and it may be a long time before you hit anything of value. However, it is an enjoyable hobby and provides a great opportunity to get outdoors, so don’t give up too quickly.

______1. How I was struck by the clear water and fresh air in my childhood! But everything has changed, that is, the clear water and fresh air are nowhere to be found again as they were. Above all, a great deal of waste hardly rots away.
_____2.More and more people are beginning to have a good knowledge of the importance of a safer and cleaner environment, which in turn forces the business to be cleaned up.
____3. I’m very much fond of growing some vegetables of my own in my small garden, for many vegetables on sale in markets are actually becoming more and more dangerous as a result of widespread pesticides.
____4. Nowadays it is very convenient for consumers to find and buy green food in supermarkets as they are clearly marked.

A.“Organic produce is always better,” Gold said. “The food is free of pesticides, and you are generally supporting family farms instead of large farms. And more often than not it is locally grown and seasonal, so it is more tasty.” Gold is one of a growing number of shoppers buying into the organic trend, and supermarkets across Britain are counting on more like him as they grow their organic food business. |

B.The concern for a safer and cleaner environment is making companies rethink how they do business. No longer will the public accept the old attitude of “Buy it, use it, throw it away, and forget it.” The public pressure is on, and gradually business is cleaning up its act.[ |

C.Many cities around the world today are heavily polluted. Careless methods of production and lack of consumer demand for environment-friendly products have contributed to the pollution problem. One result is that millions of tons of glass, paper, plastic, and metal containers are produced, and these are difficult to get rid of. |

D.Only a few years ago, it was impossible to find green products in supermarkets, but now there are hundreds. Some supermarket products carry labels (标签) to show that the product is green. Some companies have made the manufacturing (制造) of clean and safe products their main selling point and emphasize it in their advertising. |
E. Market research shows that Gold and others who buy organic food can generally give clear reasons for their preferences - but their knowledge of organic food is far from complete. For example, small amounts of pesticides can be used on organic products. And about three quarters of organic food in Britain is not local but imported to meet growing demand. “The demand for organic food is increasing by about one third every year, so it is a very fast-growing market,” said Sue Flock, a specialist in this line of business.
