The rates②of change that we’re noticing are much higher than expected. If these rates continue, it is not unlikely that Greenland could shrink③by several tens of percent this century. However, it’s not known how quickly this coastal response of the Greenland ice sheet melting will have an effect on the vast inland ice.
Greenland is the world’s largest island, covering an area more than three times the size of Texas. Some 81 percent of it is covered by ice, and there are many glaciers. Glaciers are like slow-moving rivers of ice. Where a glacier meets the sea, its weight keeps it firmly resting on the bottom. A glacier’s front is the point where the water is deep enough that the glacier floats.
Since the 1970s, the front of Helheim stayed in the same place. Then it began melting rapidly, moving back 4.5 miles from 2001 through this past summer. It has also grown thinner, from top to bottom, by more than 130 feet since 2001. And over these past four years, its trip to the sea has sped up from about 70 feet per day to nearly 110.
The melting is driven by a warmer climate. Temperatures in Greenland have risen more than five degrees Fahrenheit in the last decade. Since most of Greenland’s ice is on land, seas will rise as the ice melts. If all Greenland’s ice sheet melted, oceans would be 15-20 feet higher. Nobody expects that to happen anytime soon.
Notes:
① glacier n. 冰川
② rate n. 比率
③ shrink v. 缩小

The project, though, has run into fears that it could worsen Venice’s problems. The city throws waste into the lagoon, and environmentalists fear the dams will cause this pollution to become worse if there is no tide to wash it out regularly. But if there is a tide, the flow can wash away about 550 million cubic meters of the lagoon in a single day, which means that by leaving the dam open for only a few hours, the waste should be cleaned out.
Another piece of good news is that British scientists are confident that the dams will be able to face an expected rise in sea levels caused by global warming. The gates are designed to stand a 22-centimetre rise in sea levels, but many scientists expect a global rise in sea levels of 31cm by 2100.
However, Trevor Davies and Isabel Trigo from University of East Anglia believe the dams are unlikely to broken. Climate change will weaken the local storms in the Adriatic that are the main cause of flood risk. Floodwaters are also a seasonal danger in Venice, usually because of a combination of spring tides and strong winds.
Venice, which rests on wooden piles driven into boggy③ ground, has been sinking for centuries, worsening the encroachment by the sea.
Notes:
① dam n. 大坝
② lagoon n. 泻湖
③ boggy adj. 泥泞的
④ encroachment n. 蚕食

2. If the project comes into use, the waste in the lagoon ______.
A. will be washed away by the tides B. will be sent to the higher places
C. will be carried away by workers D. will have to be reused by humans

A. the dams are higher than the buildings in Venice
B. there will be no tides or floods in the future
C. the climate all over the world will soon be cold
D. the storms in the Adriatic will be weaker in the future
4. According to the text, we can infer that Venice ______.
A. has been sinking for hundreds of years
B. may suffer from spring tides and strong winds
C. will be under the sea sooner or later
D. will be a city with dams around except 78 gates

They also tend to prefer instant messaging to e-mail, and they are depending on the Internet more frequently than before to communicate with others who have the same professions, hobbies and political interests. Online purchases still remain unpopular in China. Three-quarters of users surveyed have never bought anything over the Internet, and only 10 percent make purchases even once a month. Among those who do buy online, most pay for entertainment while others buy phone cards, or computer hardware or software.
“Many people don’t trust the quality of goods bought online,” Guo said Wednesday. “If they buy it in a store and don’t like it, they can easily bring it back.”
The survey was done in five major cities: Beijing, Shanghai, Guangzhou, Chengdu and Changsha. Results do not necessarily project countrywide because Internet use in rural areas is lower than in cities. Guo describes the typical netizen in the five cities surveyed as young, male, richer and more highly educated. Males make up two-thirds of the Internet community, and more than 80 percent of users are under 24. Among people ages 25 to 29, 60 percent to 80 percent go online.
China has more than 100 million people online, second in the world to the United States.
1. A typical Chinese Internet user will be the one who ______.
A. likes to send e-mails B. likes to buy goods online
C. likes to pay for entertainment D. likes the games sites
2. Online purchases still remain unpopular in China mainly because ______.
A. it is more difficult for sales returns B. people haven’t computers
C. people can’t have a look at the goods D. goods bought online are of low quality
3. Which of the following words fails to describe the typical netizens in the five cities?
A. well educated B. richer C. female D. young
4. According to the text, which of the following shows the right relation between online people and their ages?
A.

The report, based on scores of the 2005 high school graduates who took the exam, some 1.2 million students in all, also found that fewer than one in four met the college-readiness benchmarks①in all four subjects tested: reading comprehension, English, math and science.
ACT sets its college-readiness benchmarks — including the reading comprehension benchmark, which is new this year—by correlating②earlier students’ ACT scores with grades they actually received as college freshmen. Based on that data, the benchmarks indicate the skill level at which a student has a 70 percent likelihood③ of earning a C or better, and a 50 percent chance of earning a B or better.
Among those who took the 2005 test, only 51 percent achieved the benchmark in reading, 26 percent in science, and 41 percent in math; the figure for English was 68 percent. Results from the new optional ACT writing test, which was not widely taken this year, were not included in the report.
About 40 percent of the nation’s 2005 high school graduates took the ACT, and the average overall score was unchanged from the year before. Minority students make up 27 percent of all ACT test takers. Besides, there are also other worrying trends in the ACT report as well, including a continuing decline in the percentage of students planning to major in engineering, computer science and education.
Notes:
① benchmark n. 基准
② correlate v. 联系
③ likelihood n. 可能性
1. The report from ACT mainly tells readers the problem that ______.
A. few minority students graduates took ACT
B. many who intend to go to college are not ready
C. the college-readiness benchmarks is high this year
D. the tests for some subjects are too difficult
2. According to the benchmarks in 2005, about how many students will not earn C?
A. 30 percent. B. 70 percent. C. 50 percent. D. 26 percent.
3. Which of the following pictures can correctly show the numbers of the students who achieve the benchmark in different subjects?
A.

D. The average score of 2005 ACT participants changed greatly.
A Low-Carbon Economy (LCE) refers to an economy which has a minimal emission of greenhouse gas (GHG), namely, carbon dioxide into the biosphere(生物圈). Recently, most of the scientists and the public hold the opinion that the climate is changing because there is such an accumulation of CO2 in the atmosphere due to human activities. The over-concentration of these gases is producing global warming that affects long-term climate, with negative impacts on humanity in the foreseeable future. LCE, therefore, is proposed as a means to avoid catastrophic climate change.
All nations which are considered carbon intensive societies and societies which are heavily populated should become zero-carbon societies and economies. Several of these countries have promised to become "low carbon" but not entirely zero carbon, and claim that emissions will be cut by 100% by balancing emissions rather than ceasing all emissions.
Nuclear power and the strategies of carbon capture and storage (CCS) have been proposed as the primary means to achieve a LCE while continuing to exploit non-renewable resources. Scientists are afraid, however, whether the spent-nuclear-fuel can be stored, and whether it is secure. Also they are not certain about the costs and time needed to successfully implement CCS worldwide and whether the stored emissions will leak into the biosphere or not. Alternatively, many have proposed renewable energy should be the main basis of a LCE, but, they have their associated problems of high-cost and inefficiency; this is changing, however, since investment and production have been growing significantly in recent times. Furthermore, it has been proposed that to make the transition to an LCE economically attractive we would have to attach a cost (per unit output) to GHGs through means such as emissions trading and/or a carbon tax.
A LCE is aimed to integrate all aspects of itself from its manufacturing, agriculture, transportation to power-generation around technologies that produce energy and materials with little GHG emission and thus around populations, buildings, machines and devices which use those energies and materials efficiently and dispose of or recycle its wastes so as to have a minimal output of GHGs.

I. 72 : an economy with a minimal output of GHG
II. 73 of the present economy:
● global warming
