All too often , a choice that seems sustainable(可持续的)turns out on closer examination to be problematic. Probably the best example is the rush to produce ethanol(乙醇)for fuel from corn . Corn is a renewable resource —you can harvest it and grow more, almost limitlessly. So replacing gas with corn ethanol seems like a great idea.
One might get a bit more energy out of the ethanol than that used to make it, which could still make ethanol more sustainable than gas generally, but that’s not the end of the problem. Using corn to make ethanol means less corn is left to feed animals and people, which drives up the cost of food. That result leads to turning the fallow land — including, in some cases, rain forest in places such as Brazil — into farmland, which in turn gives off lots of carbon dioxide(CO2)into the air. Finally, over many years, the energy benefit from burning ethanol would make up for the forest loss. But by then, climate change would have progressed so far that it might not help.
You cannot really declare any practice “sustainable” until you have done a complete lift-cycle analysis of its environmental(环境的)costs. Even then, technology and public policy keep developing, and that development can lead to unforeseen and undesired results. The admirable goal of living sustainable requires plenty of thought on an ongoing basis.What might directly cause the loss of the forest according to the text?
| A.The growing demand for energy to make ethanol. |

| A.the energy benefit | B.the forest loss |
| C.climate change | D.burning ethanol |
The author thinks that replacing gas with corn ethanol is
| A.impractical | B.acceptable | C.admirable | D.useless |

A new generation addiction is quickly spreading all over the world. Weboholism, a twentieth century disease, affects people from different ages. They surf the net, use e-mail and speak in chat rooms. They spend many hours on the computer, and it becomes a compulsive habit. They cannot stop, and it affects their lives.
Ten years ago, no one thought that using computers could become compulsive behavior that could affect the social and physical life of computer users. This obsessional behavior has affected teenagers and college students. They are likely to log on computers and spend long hours at different websites.
They become addicted to computers and gradually their social and school life is affected by this situation. They spend all free time surfing and don’t concentrate on homework, so this addiction influences their grades and success at school. Because they can find everything on the websites, they hang out there. Moreover, this addiction to websites influences their social life.
They spend more time in front of computers than with their friends. The relation with their friends changes. The virtual life becomes more important than their real life. They have a new language that they speak in the chat rooms and it causes cultural changes in society.
Because of the change in their behavior, they begin to isolate themselves from the society and live with their virtual friends. They share their emotions and feelings with friends who they have never met in their life. Although they feel confident on the computer, they are not confident with real live friends they have known all their life. It is a problem for the future.

The 115-year-old prestigious (有名望的)Oxford Dictionary will now include popular new Chinese terms like“shanzhai” “youtiao” and “fangnu”, as part of the modern Chinese language.
As China plays a more and more important role in the world economy, the Chinese language is forever developing, attracting more attention from people who want to understand this ancient yet lively language.
For instance, the word “shanzhai” is used to describe the countless knockoffs(名牌仿制品)of iPhones or designer bags imprinted with Louis Vuitton logos.
Another new term in the new edition is the word “fangnu”, or a “mortgage slave” —a term used to describe the phenomenon in large cities where well-educated youth complain of a miserable existence due to the heavy burden of a home mortgage.
All these new or often fashionable terms can be found in the new Oxford English –Chinese, Chinese-English dictionary that was unveiled(公布于众的)in the recently concluded Beijing International Book Fair last week.
The dictionary now is available for retail sales since the beginning of this month.This dictionary is the largest single volume English-Chinese, Chinese-English dictionary and contains 670,000 words and phrases after five years of preparation.Sixty editors from the Oxford University Press and its partner in China—the Foreign Language Teaching and Research Press—worked together on the project.According to Julie Kleeman, the dictionary’s chief editor, most of the firm’s editors were Chinese, while about one fourth were native-English speakers.
“We don’t want to make it florid(绚丽的), we want it to be modern and conversational...many of the words in the present dictionary are no longer in use,” said Kleeman.“The need for studying Chinese by foreigners today is totally different from decades ago...Precise, native and practical—that is our main advantage,” she said.
Kleeman said newer publications updates will be available only for the online version as language often changes too quickly for book versions to keep pace.The online version will also offer a Chinese phonetic pronunciation guide.The online version, allowing access via different platforms from the PC to the iPad, will be ready “as soon as possible”, Kleeman said. According to the above passage, we learn that ________.
| A.knockoffs can be found in China but not very often. |
| B.the Oxford University Press made the dictionary without outside aid. |
| C.most Chinese editors are also native speakers of English. |
| D.well-educated youth in China’s big cities have difficulty buying houses. |
The possible reason why newer publications updates are not available for book versions is that ________.
| A.book versions can’t keep up with the changes of language. |
| B.the computer network is available everywhere. |
| C.book versions can’t offer a Chinese phonetic pronunciation guide. |
| D.computer technology like the PC and the iPad keeps pace with language. |
What is the main idea of the passage?
| A.New Chinese terms like “shanzhai” and “fangnu” have got into Oxford Dictionary. |
| B.The latest Oxford English-Chinese, Chinese-English Dictionary is on the market. |
| C.Oxford Dictionary has become more fashionable due to the Chinese language. |
| D.Beijing International Book Fair was where the new Oxford Dictionary was published |
Hundreds of students from around the world gathered in New York City last week for the Microsoft Imagine Cup finals. They came to present their ideas for using technology to solve world problems.
Microsoft education director Suzi Levine says the nine-year-old program began mainly as a competition to create technology.
SUZI LEVINE: "When we realized that students really actually want to have a purpose for what they're creating, we introduced the idea of inspiring them with the UN Millennium Development Goals and suggesting that they use those for their muse(灵感). "This past year we also rolled out something called the Imagine Cup Solve This library(创新杯求解计划知识库), where IGOs, NGOs and nonprofits can submit some of the technical challenges that they would like students to consider for their solutions."
Microsoft says over 350,000 high school and college students registered for this year's competition. Judges chose more than four hundred of them to attend the finals.
SUZI LEVINE: "One from Thailand was called NewKrean, where they created a Windows Phone 7 application that allows you to broadcast your location to your social network of friends so that you can be more easily rescued." They named their application Terra.
Suzi Levine says there were also ideas from Egypt inspired by the revolution that overthrew president Hosni Mubarak in February.
SUZI LEVINE: "One was to use Bluetooth as sort of a Twitter equivalent so that if the government shuts down the Internet, you actually can still have a massive social distribution."
Students competed in nine categories. For example, in software design the top prize of twenty-five thousand dollars went to Team Hermes from Ireland. The students developed a device for cars to collect information on road conditions, driving behavior and traffic incidents.
A team from Taiwan's National Tsing Hua University won first place in the embedded(内嵌的) development category. They developed a network of wireless devices to help plot the safest escape routes during a fire.

People in the UK often talk about their homes: their mortgages (按揭), the interest rates, and rising prices. Here’s a guide to some of the words and phrases you might come across.
It’s a good idea in the UK to arrange a mortgage with a bank before you start looking. This is when the bank tells you how much money they will lend you so you have a good idea of how much you can afford.
The next step is to go to an estate agent and see what sort of properties they have available in your budget range and in your area. If you see something you like, the estate agent will arrange for you to view the property, so that you can see the house or flat for yourself.
If you see something that takes your eye, you put in an offer. The vendor (卖家) can accept or decline this offer, and if the vendor accepts it, you can move forward with the sale. However, as you don’t pay any money at this point, the offer isn’t legally binding (具有约束力), and in theory, you can pull out of the offer at any time that you like.
Your next step will probably be to get a structural survey done. A qualified surveyor will inspect the house and write a report that illustrates any structural problems, like damp or drainage problems.
If you still want to go ahead with the sale, you need to appoint a lawyer to do the legal paperwork.. If you already own a house, you might also be busy trying to sell it. Many house owners prefer to sell to first-time buyers (those people who don’t already own a home), as they are not in a chain (waiting for other people to buy the house before they can buy their next house).
Finally, once the contracts are signed and exchanged, you complete on your house. You get the keys and you can move in whenever you want. Then you might want to throw a house-warming party. Congratulations! Which of the following shows the right order of what happens before the people in the UK move into a new house?
a. ask for a company which represents others of properties
b. decide how much to borrow from the bank
c. examine the structure of the house
d. hire a lawyer and make a contract
e. offer the seller the right money
f. visit the house and discuss a price with the seller
| A.b, a, f, d, c, e | B.b, a, f, c, d, e |
| C.b, a, f, e, d, c | D.b, f, d, e, c, a |
According to the passage, these statements are correct EXCEPT ___________.
| A.People can borrow the whole money for a new house from a bank. |
| B.People care for mortgages, interest rates and the prices &house. |
