Low-carbon Future: We Can Afford to Go Green

Tackling climate change will cost consumers the earth. Those who campaign for a green revolution are out to destroy our western lifestyles. Such are the cries of opponents of emissions cuts, and their message has political impact: a number of surveys have found that the enthusiasm of voters for policies to reduce climate change falls off as the price tag increases.

However, a new modeling(模型化) exercise suggests that these fears are largely unfounded. It projects that radical cuts to the UK’s emissions will cause barely noticeable increases in the price of food, drink and most other goods by 2050. Electricity and petrol costs will rise significantly, but with the right policies in place, say the modellers, this need not lead to big change in our lifestyle.

“These results show that the global project to fight climate change is feasible,” says Alex Bowen, a climate policy expert at the London School of Economics. “It’s not such a big ask as people are making out.”

Although it is impossible to precisely predict prices four decrease from now, the exercise is one of the most detailed examinations yet of the impact of climate change policies on UK consumers. It provides a useful rough guide to our economic future.

Though its results speak directly to the UK consumers, previous research has come to similar conclusions for the US. In June, one study found that if the US were to cut emissions by 50 per cent by 2050, prices of most consumer goods would increase by less than 5 per cent. The findings are also consistent with analyses by the Pew Center on Global Climate change in Washington DC. “Even cutting emissions by 80 per cent over four decades has a very small effect on consumers in most areas,”says Manik Roy of the Pew Center. “The challenge is now to convince consumers and policy-Makers that this is the case.”

The Intergovernmental panel on Climate Change recommends that wealthy nations cut their emissions to between 80 and 95 per cent below 1990 levels by 2050 in order to avoid the

Model Test One

worst effects of climate change. The UK government aims to reduce its contribution by 80 per cent and leaders of the other G8 nations have discussed following suit. To meet this goal, industries will have to slash fossil fuel consumption, and low-carbon power sources will have to massively expand. Companies will have to pay increasingly higher prices for the right to emit greenhouse gases.

How will this affect the average citizen's wallet? To measure the impact of the 80 per cent target on the UK population, New Scientist approached Cambridge Econometrics, a firm known for its modeling of the European economy. The firm used historic economic data to predict the impact of emissions reductions on prices in over 40 categories of goods and services. It compared the impact of the 80 per cent cut with a baseline scenario in which the government takes no action other than the limited emissions restrictions already in place as a result of the Kyoto protocol(京都协议书).

Most of the price increases are a consequence of rising energy costs, in part because coal and gas are replaced by more expensive low-carbon sources. The price of electricity is projected to be 15 per cent higher in 2050 compared with the baseline. In today's prices, that would add around ￡5 onto typical monthly household electricity bills. It will also result in higher prices elsewhere, as every industrial sector uses electricity.

But electricity and other forms of energy make up only a small part of the price of most goods. Other factors - raw materials, labour and taxes - are far more important. The energy that goes into producing food, alcoholic drinks and tobacco, for example, makes up just 2 per cent of the consumer price. For motor vehicle purchases and hotel stays, the figure is 1 per cent. Only for energy-intensive industries does the contribution climb above 3 per cent.

As a result, most products cost just a few per cent more by 2050. At current prices, going low-carbon is forecast to add around 5 pence to the price of a slice of bread or a pint of beer. The price of household appliances such as washing machines rises by a few pounds.

There is one major exception to the pattern. Airlines do not currently have a low-carbon alternative to jet fuel. Unless one is found, they will bear the full burden of carbon pricing, and average fares will rise by at least 140 per cent - raising the cost of a typical London to New York return trip from around ￡350 to ￡840.

Achieving the overall picture of low prices does require government action. The model forecasts that by 2050 natural gas and petrol will cost 160 per cent and 32 per cent more respectively. To avoid large price rises in home heating and road transport while still hitting the 80 per cent target, the Cambridge researchers had to build two major policies into their analysis. They assumed that future governments will provide grants to help switch all domestic heating and cooking to electricity, and invest in the basic facilities needed for electric cars to almost completely replace petroleum-fuelled vehicles.

Both policies have been discussed in recent UK government strategy documents, though the detail of how they would be implemented still needs further discussion. Firm policies must follow if ambitious emissions cuts are going to be made, says Chris Thoung of Cambridge Econometrics.

So is tackling climate change going to be easier than expected, in terms of consumer costs? While the Cambridge Econometrics model is widely respected and regularly used by the UK government's climate change advisers, any attempt to forecast four decades ahead can be diverted by unforeseen events. That leads some economists to question the model's results.

Model Test One

For example, companies could move to countries with less strict carbon regulations, points out Richard Tol of the Economic and Social Research Institute in Dublin, Ireland. Incomes in the UK would fall, making goods relatively more expensive. Tol also questions whether it is reasonable to use historical prices as a basis for projecting beyond 2020.

Despite this, the Cambridge Econometrics results, together with other recent studies, do provide a useful guide for governments, says Michael Grubb of the University of Cambridge. They suggest that the overall challenge is conquerable, even if many of the details will only become clear in years to come.

Passage One

Pregnancy mothers are getting a new tool to help keep themselves and their babies healthy: pregnancy tips sent directly to their cell phones.

The so-called text4baby campaign is the first free, health education program in the U.S. to harness the reach of mobile phones, according to its sponsors. Organizers say texting is an effective means of delivering wellness tips because 90 percent of people in the U.S. have cell phones.

"Especially if you start talking about low-income people, cell phones are the indispensable tool for reaching them and engaging them about their health," said Paul Meyer, president of

Model Test One

Voxiva, a company which operates health texting programs in Africa, Latin America and India.

Studies in those countries have shown that periodic texts can reduce smoking and other unhealthy behaviors in pregnant mothers.

Meyer said the U.S. program, run by Voxiva, will be the largest health-related texting program ever undertaken.

Under the new service, mothers-to-be who text "BABY" to a specified number will receive weekly text messages, timed to their due date or their baby’s birth date. The messages, which have been scanned by government and nonprofit health experts, deal with nutrition, immunization and birth defect prevention, among other topics. The messages will continue through the baby’s first birthda y.

Baby is expected to be announced Thursday morning by off icials from the White House’s Office of Science and Technology Policy. Government officials will be publicizing the campaign in speeches and promotional materials.

Organizers hope the effort can curb premature （早产的）births, which can be caused by poor nutrition, excessive stress, smoking and drinking alcohol. About 500,000 babies are born prematurely in the U.S. each year. The nonprofit is among the sponsors of the campaign.

"The real scary thing is that we’re an industrialized nation and we’re n ot doing very well on infant death rate, and we know prematurity is a big part of that," said the group’s director, Judy Meehan.

Currently the U.S. ranks 30th worldwide for infant death rate, according to Meehan, behind most Western European nations.

Researchers at the George Washington University have agreed to evaluate the effectiveness of baby by measuring health trends for mothers and newborns.

Passage Two

As a group of young African immigrants struggles to adapt to life in the United States, an after-school drama program at White Oak Middle School aims to make their lives easier by first making them a little harder.

Project X is a program that uses drama, dance, poetry and other creative outlets to help students discuss the tough and sometimes painful problems they face as pre-teen immigrants with significant language barriers. A final unveiling of their creation will be performed for friends and family at the end of the year at Imagination Stage.

Wanjiru Kamau, coordinator of White Oak’s African Club said it’s important to give troubles to group members to help them find their place at the school. "It comforts those who are uncomfortable, and it discomforts those who are comfortable," Kaman said of Project X.

Kamau teamed up with Imagination Stage after she noticed that many African students seemed uncomfortable talking about problems, such as being laughed at by their fellow students about how they look and talk. When most of the kids join the club, they speak little or no English, Kamau said. Each week, the club typically draws five to 10 students who are originally from Africa for discussion sessions and the Project X program.

"We’re going to express ourselves through our words and our actions, and that’s po werful," said teaching artist Meg Green as she introduced fill-in-the-blank poems the students wrote about their identities.

One student, Franck Ketchouang, 13, wrote, "I am from the world; I am love," which drew oohs and aahs from the group. Ketchouang has been in the United States less than a year, said Program Coordinator Chad Dike. When Ketchouang started attending Project X, he had been in the United States for two months and spoke no English. Now he’s one of the group’s most outgoing members and helps translate instructions from English to Creole for the group’s newest member, who is from Haiti.

Many people will give up when there’s a language barrier, "but these students prove them wrong," Kamau said. "You do have something to give. You are important. When TV, media, etc. are bringing them down, this program is bringing them up."

62. Project X is intended for helping the young African immigrants to_________.

A) get over language barriers

B) overcome tough problems

C) enrich after-school life

D) become more creative

63. How well the members learn in the Project X program is demonstrated by _____.

A) their annual creative performances

B) their annual scores gained at school

C) the comments of friends and family

D) the comments of the program teachers

64. What do we know about the imagination Stage?

A) It’s established by Kamau for Project X

B) It’s operated once at the end of each year.

C) It’s projected designed by White Oak Middle School.

D) It’s a cooperative partner of White Oak’s Africa Club.

65. According to the author, what Franck Ketchouang wrote was_________.

A) silly B) simple C) remarkable D) disputable

66. The passage is written mainly to ________.

A) call for more attention to immigrants

B) inspire immigrants to never give up

C) advocate White Oak’s African Club

大学英语四级模拟试题四(附含答案解析)

大学英语四级模拟题四 Part One Reading Comprehension (2’×10 = 20’) Directions: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter on the Answer Sheet with a single line through the centre. Passage One Air pollution can spread from city to city. It even spreads from one country to another. Some northern European countries have had “black snow”from pollutants that have traveled through the air from other countries and have fallen with the snow. So air pollution is really a global problem. Air pollution can kill babies, older people, and those who have respiratory（呼吸的）diseases. As found in cities, air pollution increases the risks of certain lung diseases. Air pollution can cause both airplane and car accidents because it cuts down visibility （能见度）. There are other possible health dangers from air pollution that we don’t know much about. For example, scientists are trying to find out whether chemicals that reach us from the air may cause changes in our cells. These changes might cause babies to be born with serious birth defects. Scientists are trying to learn how all the many chemicals are apt（易于的）to take into our bodies from air, water, food, and even medicines act together to affect our health and the way our bodies work. That is another reason why it is so important to begin to control pollution now instead of waiting until we learn all the answers. Air pollution costs us a lot of money. It corrodes（腐蚀）our buildings. It damages farm crops and forests. It has a destructive effect on our works of art. The cost of all this damage to our government is great. It would be much more worthwhile, both for us and for the government, to spend our tax dollars on air pollution control. 1. Air pollution may lead to airplane accidents because . A. it may cause pilots to be ill B. engines may fail from the air-borne dirt C. visibility is reduced D. it brings a lot of black snow 2. Scientists are trying to find a link between pollution and . A. intelligence levels B. birth problems C. man’s behavior D. the nervous system 3. Scientists have not yet determined . A. all of the effects of pollution on the human body B. how pollution can be controlled successfully C. when the atmosphere first became polluted D. how some snow becomes black 4. The author suggests that before air pollution becomes more serious, . A. factories will be forced to stop operating B. buildings should be protected C. the earth will begin to grow colder D. more money should be spent to solve the problem 5. We can conclude that . A. civilization may be ruined if pollution is not controlled B. pollution is more serious in Europe than it is in America C. most people do not know that pollution is a serious problem D. we should learn all the answers before we begin to control pollution Passage Two Stiletto heels could be banned from the workplace because of health and safety reasons, according to British Trade Union bosses. The Trade Union Congress, predominantly male, has proposed a motion arguing that high heels are disrespectful to women while they also contribute to long term injuries. They propose instead that women wear “sensible shoes”with an inch heel limit in an attempt to avoid future foot and back pain as well as injuries. The motion is due to be debated at next month’s conference. The motion states: “Congress believes high heels may look glamorous on the Hollywood catwalks but are completely in appropriate for the day-to-day working environment. Feet bear the burden of daily life, and for many workers prolonged standing, badly fitted footwear, and in particular high heels can be a hazard. Around two million days a year are lost through sickness as a result of lower limb disorders. Wearing high heels can cause long-term foot problems and also serious foot, knee and back pain and damaged joints. Many employers in the retail sector force women workers to wear high heels as part of their dress code. More must be done to raise awareness of this problem so that women workers and their feet are protected.” Nadline Dorries, the Tory Member of Parliament, however criticized the motion and said the extra height heels give women can help them when in the workplace. “I’m 5ft 3in and need every inch of my Christian Louboutin heels to look my male colleagues in the eye,”she said. “If high heels were banned in Westminster, no one would be able to find me. The Trade Union leaders need to get real, stop using obvious sexist tactics by discussing women’s

Calculate for a moment what could be done with even a part of those hours. Five thousand hours, I am told, are what a typical college undergraduate spends working on a bachelor's degree. In 10,000 hours you could have learned enough to become an astronomer or engineer. You could have learned several languages fluently. If it appealed to you, you could be reading Homer in the original Greek or Dostoyevsky in Russian. If it didn't, you could have walked around the world and written a book about it. The trouble with television is that it discourages concentration. Almost anything interesting and rewarding in life requires some constructive, consistently applied effort. The dullest, the least gifted of us can achieve things that seem miraculous to those who never concentrate on anything. But Television encourages us to apply no effort. It sells us instant gratification(满意). It diverts us only to divert, to make the time pass without pain. Television's variety becomes a narcotic(麻醉的), nor a stimulus. Its serial, kaleidoscopic (万花筒般的)exposures force us to follow its lead. The viewer is on a perpetual guided tour: 30 minutes at the museum, 30 at the cathedral, 30 for a drink, then back on the bus to the next attraction—except on television., typically, the spans allotted arc on the order of minutes or seconds, and the chosen delights are more often car crashes and people killing one another. In short, a lot of television usurps(篡夺;侵占) one of the most precious of all human gifts, the ability to focus your attention yourself, rather than just passively surrender it. Capturing your attention—and holding it—is the prime motive of most television programming and enhances its role as a profitable advertising vehicle. Programmers live in constant fear of losing anyone's attention—anyone's. The surest way to avoid doing so is to keep everything brief, not to strain the attention of anyone but instead to provide constant stimulation through variety, novelty, action and movement. Quite

第1篇 Teamwork Teamwork is just as important in science as it is on the playing field or in the gym. Scientific investigations are almost always carried out by teams of people working together. Ideas are shared, experiments are designed,data are analyzed, and results are evaluated and shared with other investigators. Group work is necessary, and is usually more productive than working alone. Several times throughout the year you may be asked to work with one or more of your classmates. Whatever the task your group is assigned, a few rules need to be followed to ensure a productive and successful experience. What comes first is to keep an open mind, because everyone's ideas deserve consideration and each group member can make his or her own contribution. Secondly, it makes a job easier to divide the group task among all group members. Thirdly, always worktogether, take turns, and encourage each other by listening, clarifying, and trusting one another. Mutual support and trust often make a great difference. Useful words and expressions: playing field n. 运动场 productive adj. 多产的，有生产价值的 productive force 生产力 productive labor 有价值的劳动 a productive farm 肥沃的农场 a productive writer 多产作家 investigation n. 调查，研究 (be) under investigation 在调查研究中 bear investigation 经得起考查，不怕追查 keep an open mind 不抱成见，抱着虚心态度 make a great difference 有很大差别，有很大影响听力源文件下载地址：https://www.wendangku.net/doc/193235028.html,/s/1i3iV5Tb

大学英语四级考试模拟试卷及参考答案(第一套)

大学英语四级考试模拟试卷及参考答案(第一套） Part II Reading Comprehension (35 minutes) Directions: There are 4 reading passages in this part. Each passage is foll owed by some questions or unfinished statements. For each of them there are fou r choices marked A), B), C) and D). You should decide on the best choice and ma rk the corresponding letter on the Answer Sheet with a single line through the center. Passage One Questions 21 to 25 are based on the following passage. There is a difference between science and technology. Science is a method o f answering theoretical questions; technology is a method of solving practical problems. Science has to do with discovering the facts and relationships betwee n observable phenomena in nature and with establishing theories that serve to o rganize these facts and relationships; technology has to do with tools, techniq ues, and procedures for implementing the finding of science. Another distinction between science and technology has to do with the progr ess in each. Progress in science excludes the human factor. Scientists, who seek to comp rehend the universe and know the truth within the highest degree of accuracy an d certainty, cannot pay attention to their own or other people's likes or disli kes or to popular ideas about the fitness of things. What scientists discover m ay shock or anger people-as did Darwin's theory of evolution. But even an unple asant truth is more than likely to be useful; besides, we have the choice of re fusing to believe it! But hardly so with technology; we do not have the choice
