Waste to Energy—JUST BURN IT!
WHY BURN WASTE?
Waste-to-energy plants generate (产生) enough electricity to supply 2.4 million households in the US. But, providing electricity is not the major advantage of waste-to-energy plants. In fact, it costs more to generate electricity at a waste-to-energy plant than it does at a coal, nuclear, or hydropower plant.
The major advantage of burning waste is that it considerably reduces the amount of trash going to landfills. The average American produces more than 1,600 pounds of waste a year. If all this waste were landfilled, it would take more than two cubic yards of landfill space. That’s the volume of a box three feet long, three feet wide, and six feet high. If that waste were burned, the ashes would fit into a box three feet long, three feet wide, but only nine inches high!
Some communities in the Northeast may be running out of land for new landfills. And, since most people don’t want landfills in their backyards, it has become more difficult to obtain permits to build new landfills. Taking the country as a whole, the United States has plenty of open space, of course, but it is expensive to transport garbage a long distance to put it into a landfill.
TO BURN OR NOT TO BURN?
Some people are concerned that burning garbage may harm the environment. Like coal plants, waste-to-energy plants produce air pollution when the fuel is burned to produce steam or electricity. Burning garbage releases the chemicals and substances found in the waste. Some chemicals can be a threat to people, the environment, or both, if they are not properly controlled.
Some critics of waste-to-energy plants are afraid that burning waste will hamper (妨碍,阻碍) recycling programs. If everyone sends their trash to a waste-to-energy plant, they say, there will be little motive to recycle. Several states have considered or are considering banning waste-to-energy plants unless recycling programs are in place. Massachusetts, New Jersey, and New York City have delayed new waste-to-energy plants, hoping to increase the level of recycling first.
So, what’s the real story? Can recycling and burning waste coexist? At first glance, recycling and waste-to-energy seem to be at odds (不一致), but they can actually complement (弥补) each other. That’s because it makes good sense to recycle some materials, and better sense to burn others.
Let’s look at aluminum, for example. Aluminum mineral is so expensive to mine that recycling aluminum more than pays for itself. Burning it produces no energy. So clearly, aluminum is valuable to recycle and not useful to burn.
Paper, on the other hand, can either be burned or recycled—it all depends on the price the used paper will bring.
Plastics are another matter. Because plastics are made from petroleum and natural gas, they are excellent sources of energy for waste-to-energy plants. This is especially true since plastics are not as easy to recycle as steel, aluminum, or paper. Plastics almost always have to be hand sorted and making a product from recycled plastics may cost more than making it from new materials.
To burn or not to burn is not really the question. We should use both recycling and waste-to-energy as alternatives to landfilling.

For five days, Edmonton's Downtown Park is transformed into one huge stage where artists are able to share their talents, and where people are able to celebrate and enjoy themselves.

No one wants to look stupid or do the wrong thing at a new job. It is important to make the right impression from the very first day. You will face new people. You will be in a new place.
It may be difficult to know what to do. Here are five tips to help you make it through the first days at a new job:
1. First impressions can last forever. Make sure you make a good one. Before your first day, find out if your new job has a dress code (rules about what you can wear to work). If so, be sure to follow it. No matter what, always be neat and clean.
2. Get to work on time.
3. Pay attention to introductions. One of the first things that your supervisor may do is to introduce you to co-workers. These co-workers will be important to you. They are the ones who will answer your questions when the boss is not around.
4. Ask plenty of questions. Make sure that your supervisor has told you what is expected of you. If he or she has not told you your duties, ask for a list. Set daily and weekly goals for yourself.

People are overweight for many reasons, the most important one of which is that they eat the wrong foods, get the wrong types of calories per meal, and they also eat meals at the wrong time each day. Food is more powerful than any weight loss pill, because the food that you eat can either make you thin or fat. This is true because your body is like an engine, and it only needs certain foods at certain intervals(间隔)each day.
Low-calorie Diets Do Not Work
The reason people cannot lose weight by starving themselves is that their metabolism(新陈代谢)will detect any major drop in calories and it will then adjust(调整)itself by burning fewer calories each day. That is the reason why you can eat 1,000 calories per day and not lose any weight, while your friends can eat 2, 500 calories per day and not gain any weight.
Low-fat Diets Do Not Work
Many people in today’s society are buying mostly low- fat or non-fat food at the grocery store. Everybody knows how much fat is inside the food they buy. However, people are getting fatter than ever before by doing this. They are not losing weight by changing to this low-fat lifestyle.
Losing weight has nothing to do with these things. One of the most important things you can do to control your weight is to eat the proper foods, such as fruit and vegetables, eat them at the right time, and exercise every day. If people make this a habit, they will lose weight.What is the main reason why people are overweight according to the author?
| A.They eat the wrong foods at the wrong time. |
| B.They eat food with lots of calories. |
| C.They don’t take any weight loss pills. |
| D.They burn many calories every day. |
The article is written in order to _______.
| A.tell readers not to buy low-fat or non-fat food |
| B.tell readers how to lose weight |
| C.tell readers about an important scientific discovery |

To realize the aim of your weight loss plan, you should ________.
a. do exercise every day b. eat meals at the right time
c. eat fruits and vegetables d. eat low-fat or sweet food
e. eat the proper foods at each meal
| A.a, b, c, d | B.a, b, d, e |

London has a new magazine. But it’s not printed on paper. Everyone who has a television can receive it because it is on TV.
In order to read this magazine you have to have a decoder. Each page of it is numbered, so you only have to dial the number to choose which subject you want to read about. There’s a wide choice--- everything is included from cooking to the latest sports news.
If you want to read the news, the first thing you have to do is to turn to the index page which has an easy-to-remember page number, 100 for example. Then you start choosing what you want to read. The news is on pages 101 to 109, so you push out the numbers and the news appears written across your screen. Perhaps you want to go out in the afternoon, so you press 181, and a brightly colored weather map appears on the screen. But the weather is terrible so you decide to go shopping and dial 162 for a list of the week’s best bargains. But should you drive or take the train ? To answer the question you only have to press 189 for the traffic report. It’s very simple to use. But probably the best thing about the service is that it’s being updated all the time. Journalists type new material directly onto the screen and whole pages of the magazine can be replaced in minutes.
London has already had three services. One, transmitted(传输)by ITV, is called ORACLE, while the other two, on BBC, are called CEEFAX, because they let you see facts. Although CEEFAX and ORACLE have been operating for some time, they have not been well publicized. BBC engineers do not think that their idea will ever replace books and newspapers because they can be taken with you everywhere. But many people agree that this is a breakthrough as great as the invention of printing, which could change not just our reading habits but our whole way of life.What is unusual about the mew magazine in London?
| A.You can find any subject you want in it. |
| B.No paper is used to print the magazine. |
| C.There 1,000 page numbers in the index. |
| D.The speed of transmitting is astonishing. |
It’s clearly seen from the passage that ________.
| A.it takes long for the service of the magazine to be updated |
| B.most of the postmen will be out of work someday |
| C.the readers can get all kinds of information without leaving home |
| D.everyone can read the magazine if there is a television at hand |
According to the passage, the “decoder” is used to help people to ________.
| A.read the information transmitted by TV signals |
| B.broadcast special TV programs at home and abroad |
| C.dial the number to choose which subject you want to read about |
| D.find the exact page in which you can get information you need |
The passage is mainly about.
| A.a new magazine printed in London |
| B.a popular TV program with three services |
| C.a great breakthrough in printing |
| D.an up-to-date way of keeping up to date |
