If I see one more article about how wonderful alternative energy is compared to oil, I will flip(翻页). Alternative energy sources can be good---- very good in fact. And it’s pretty obvious that we’re going to need them, and that our dependence on oil is a Bad Thing. But accepting that does not mean accepting that any kind of alternative energy is a good thing.
To be a good thing, it has to have three properties: 1) It has to help reduce our dependence on oil, 2) It has to be no worse for the environment, and 3) It has to be economically practical.
Many of the things praised meet one or even two of those properties. Solar panels, for example. They can reduce our need for oil, at least in certain regions, and they’re certainly not bad for the environment. But they’re expensive. If you spend the money to make your home solar-powered, you probably won’t get back your costs for at least 15 years, which approaches the lifespan of the panels.
Certainly we need to clean up our act big time and find workable sources of alternative energy. But we also have to keep in mind that every one of these alternative-energy sources comes at a cost, which is something people seem to forget. They hear the phrase “alternative energy” and automatically assume it’s got to be good. But green isn’t always good, and oil isn’t always bad.
One seemingly “green” technology that pops up again and again is electric cars. It is praised by well-meaning people as good for the environment and a way to reduce our oil dependence, especially as oil prices continue to rise.
Electric cars are dirty. In fact, not only are they dirty, they might even be more dirty than their gasoline-powered cousins.
People in California love to talk about “ zero-emissions vehicles”, but people in California seem to be clueless about where electricity comes from. Power plants mostly use fire to make it. Aside from the new folks who have their roofs covered with solar cells, we get our electricity from generators. Generators are fueled by something---- usually coal, oil, but also by heat generated in nuclear power plants. There are a few wind farms and geothermal（地热的） plants as well, but by far we get electricity mainly by burning something.
In other words, those “zero-emissions” cars are likely coal-burning cars. It’s just because the coal is burned somewhere else that it looks clean. It is not. It’s as if the California Greens are covering their eyes ---- “ If I can’t see it, it’s not happening. “ Gasoline is an incredibly efficient way to power a vehicle; a gallon of gas has a lot of energy in it. But when you take that gas ( or another fue) and first use it to make electricity, you waste a nice part of that energy, mostly in the form of wasted heat ---- at the generator, through the transmission（传送） lines, etc.
A gallon of gas may propel your car 25 miles. But the electricity you get from that gallon of gas won’t get you nearly as far ---- so electric cars burn more fuel than gas- powered ones. If our electricity came mostly from nukes; or geothermal, or hydro, or solar, or wind, then an electric car truly would be clean. But for political, technical, and economic reasons, we don’t use much of those energy sources.
In addition, electric cars’ batteries which are poisonous for a long time will eventually end up in a landfill. And finally, when cars are the polluters, the pollution is spread across all the roads. When it’s a power plant, though, all the junk is in one lace. Nature is very good at cleaning up when things are too concentrated, but it takes a lot longer when all the garbage is in one spot.

根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。
For several years, Americans have enjoyed teleshopping-watching TV and buying things by phone. 1. In a number of European countries, people can turn on their TVs and shop for clothes, jewelry, food, toys, and many other things.
2. For example, the biggest Swedish company sells different kinds of things on TV in 15 European countries, and in one year it made $ 100 million. In France there are two teleshopping channels, and the French spend about $20 million a year to buy things through those channels.
In Germany, until last year teleshopping was only possible on one channel for 1 hour every day. Then the government allowed more teleshopping. Other channels can open for telebusiness, including the largest American teleshopping company and a 24-hour teleshopping company.3. .
Some people like teleshopping because it allows them to do their shopping without leaving their homes. With all the problems of traffic in the cities, this is an important reason, but at the same time, other Europeans do not like this new way of shopping.4. Many Europeans usually worry about the quality of the things for sale on TV. Good quality is important to them, and they believe they cannot be sure about the quality of the things on TV.
5.They will have to be more careful about the quality of the things they sell. They will also have to work harder to sell things that the buyers cannot touch or see in person.
|
A．Now teleshopping is starting in European |
|
B．They call teleshopping “Junk on the air” |
|
C．Teleshopping is becoming popular in Sweden. |
|
D．German businesses are hoping this new teleshopping will help them sell more things |
E. The need for high quality means that European teleshopping companies will have to be different from the American companies.
F. Teleshopping is popular among people
G. German teleshopping business is controlled by American.
C
Monday: Here I am, in the middle of nowhere. This camping trip idea is not getting off to a very good start. It’s raining and the tent leaks (漏). The hiking seemed to take forever, and I still can’t understand how it could all have been up hill! How did I ever let my brother persuade me into doing this? When we get home—if we ever get home—he’s going to have to do something great to get back on my good side. Maybe he should sponsor (赞助) a shopping spree（狂购）at the mall!
Tuesday: Things are looking up. The sun came out today, so we were able to leave the tents and dry out. We’re camped at the edge of a small lake that I couldn’t see before because of the rain and fog. The mountains are all around us, and the forest is absolutely beautiful. We spent most of the day dragging out everything out of our backpacks or tents and putting it where the sun could dry it out. Later in the afternoon we tried to catch the fish for dinner, but the fish were smarter than we were. At night we built a fire and sang songs happily.
Wednesday: We hiked to the far side of the lake and climbed to the top of a small peak. From there we could see how high the other mountains were and how far the forest spread around us. On the way up we passed through a snowfield!
Thursday: I caught my first fish! We followed the stream that fed the lake. After about two miles, we came to a section (区域) that Carol said looked “fishy”. She had a pack rod (竿) , which can be carried in a backpack. I asked to cast (投掷) it, and I caught a fish on my first try. Carol caught a few more. But they were just too pretty to eat for lunch, so we put them back in the stream.
Friday: I can’t believe we are going home already. It will be nice to get a hot shower, sleep in a real bed, and eat junk food, but the trip has been wonderful. We’re already talking about another camping adventure next year where we canoe (乘独木舟) down a river. It’s hard to believe, but I think this city girl has a little country blood in her veins.

Reduce, reuse, and recycle. This familiar environmentalist slogan tells us how to reduce the amount of rubbish that ends up in landfills and waterways. The concept is being used to deal with one possibly dangerous form of waste — electronic junk (电子垃圾), such as old computers, cell phones, and televisions. But this process for managing e-waste may be used in an unscrupulous way more often than not used, a recent report suggests.
“A lot of these materials are being sent to developing nations under the excuse of reuse — to bridge the digital divide,” said Richard Gutierrez, a policy researcher.
One of the problems is that no one proves whether these old machines work before they hit the seaways. Because of this, the report says, e-waste is a growing problem in Lagos, Nigeria, and elsewhere in the developing world. Much of the waste ends up being thrown away along rivers and roads. Often it’s picked apart by poor people, who may face dangerous exposure to poisonous chemicals in the equipment.
Businessmen also pay workers a little money to get back materials such as gold and copper. This low-tech recovery process could expose workers and the local environment to many dangerous materials used to build electronics. According to Gutierrez, this shadow economy exists because the excuse of recycling and reusing electronics gives businessmen “a green passport” to ship waste around the globe. “Developing nations must take upon some of the responsibility themselves,” Gutierrez said. But, he added, “A greater portion of this responsibility should fall on the exporting state.”
China, for example, has become a dumping place for large amounts of e-waste. The nation is beginning to take action to stop the flow of dangerous materials across its borders. The Chinese government, after many years of denial is finally beginning to take the lead.
【小题1】 The passage mainly tells us that _______.

| B．Poor people break up e-waste to collect some valuable materials. |
| C．The problem of e-waste is growing in developing countries. |
| D．Old computers and TVs still work before they are sent abroad. |
| A．immoral | B．wrong | C．proud | D．unsafe |
| A．developing countries should be responsible for this problem |
| B．exporting countries should be mainly responsible for this problem |
| C．neither rich nor poor countries should be blamed for this problem |
| D．poor countries should be blamed for this problem |
With the rapid progress of technology, the English language is changing fast. All the people have to face a choice: either ignore the development of the language and spend the rest of our lives wishing Shakespeare were alive, or keep pace with the Internet age, welcoming the new English which someone has once called Weblish. “you can’t avoid it for the simple reason that wherever a new language comes along, it surely impacts (影响) the language as a whole,” says Dr David Crystal, a famous language professor at the University of Wales.
However, there is great trouble with keeping up with the new English because there are so many new words and the old ones no longer mean what we thought they did. In the past if someone said they didn’t have “Windows”, you would have to suppose they lived in a cave without windows. But now, it is probably because they use a Mac, which is a computer. Spam, which once meant a not-so-good-kind of canned meat, now stands for unwanted “junk (垃圾)” email.
Spelling is changing too. Weblish loves to see nouns happily become verbs ( for example, “Please bookmark this site”), and verbs become nouns (“Send me the download”).Verbs and prepositions are regularly thrown together to become new nouns or adjectives(for example, dial-up, logon, print-out, pull-down, upload), while others are created from a simple pairing of nouns: cyberspace, ethernet, Internet, hyperlink, metatag and netspeak.
【小题1】 We can infer from the first paragraph that _____ .
| A．English has completely become Weblish |
| B．some people wish Shakespeare were still alive |
| C．people may have different attitudes towards Weblish |
| D．people who know English have to learn a new language |
| A．Now English has many new words. |
| B．English words have changed a lot. |
| C．Old English words are no longer used at all. |
| D．People have difficulty in understanding some new words related to computers and the Internet. |
| A．Technology and English |
| B．Keep Up with the Latest Weblish |
| C．Don’t Forget English |
| D．The Advantage and Disadvantages of Weblish |
