17.A new study showed that one of the best ways to control greenhouse gas emissions(溫室氣體排放) is to eat less meat.In fact,the study showed that meat consumption(食用量) in developed countries should be cut by 50% per person before 2050.
Meat production and consumption are expected to rise very quickly to a high level by 2050.That's because the global population is expected to grow from the present 7billion to 9billion.But also,the diets of people in many developing countries are changing.Countries that are developing rapidly are seeing a fast rise in protein consumption,especially red meat.
Dr.Eric Davidson,the president and senior scientist at the Woods Hole Research Center in Massachusetts,said changing the way people eat can have a great effect on greenhouse gas emissions.People in developed countries,he said,already eat much more protein than the daily requirement.
"In the developed world,there is large room for us to manage the frequency with which we eat meat.If there is a growing need for meat,that is going to end up requiring use of more nitrogen fertilizer(肥料) and production of more livestock manure(家畜糞肥),both of which end up resulting in release of various forms of greenhouse gases to the atmosphere,"he said.
Davidson said farmers should be encouraged to use fertilizers and manure in a more careful way."If we want to meet the greatest goal of making harmful climate change under control,we need to improve the efficiency(效能) with which we use fertilizers in agriculture.We need to improve the efficiency of the management of manure.And we also need to consider changes in dietary patterns(飲食方式).And that means hopefully better diets in the developing world and better balanced diets in the developed world,"he said.
Even if it were possible to turn off all harmful greenhouse gas emissions today,he said climate change would continue."But that does not mean that we can do nothing for  it  now,because the sooner we start to take action,the more choices our children and grandchildren will have in terms of being able to feed themselves and have comfortable lifestyles without environmental degradation(退化),"he said.

28.According to the new study,eating less meat isD.
A.one of the best ways to keep healthy
B.a(chǎn)n effective way to develop the economy
C.the best way to control greenhouse gas emissions
D.a(chǎn) good way to protect the environment
29.In paragraph 4,what does Dr.Eric Davidson mainly talked about?C
A.The harms of releasing various greenhouse gases
B.The side effects of producing fertilizers and manure
C.The effects of growing need for meat on the environment

30.The underlined word"it"in the last paragraph refers toB.
A.the environment
B.climate change
C.greenhouse gases
D.the lifestyle
31.In Dr.Eric Davidson's opinion,C.
A.it's important to encourage farmers to use fertilizers
B.our future generations will live more comfortably
C.a(chǎn) balanced diet is helpful in controlling climate change

12.Driving in traffic can be extremely stressful.Pedestrians appear out of nowhere,cars suddenly pull out of parking spots,and roads become slippery due to rain or snow.Knowing when to brake and when to accelerate in such situations is hard enough for a human driver,let alone a robotic one.But several carmakers-and a few tech companies-are working to convince drivers to let driverless cars take the wheel.
       Without question,the most anticipated benefit of driverless cars is improved safety.Driverless systems will feature sensors that detect safety threats that human drivers might miss.Many carmakers already offer systems that alert drivers whenever they get dangerously close to other cars.
Also,driverless systems have the benefit of increased efficiency.Driverless cars won't waste as much gas as human drivers do,and guided by advanced GPS,they'll always take the fastest route.Once driverless cars become widely available,common people can have their own driver,and they'll just sit back and relax while their car's computer takes the wheel!
Although completely driverless cars won't be on the market for several years,the technology behind them is already appearing in phases.Two examples are the Active Lane Keeping Assist option for Mercedes-Benz cars and Ford's Traffic Jam Assist.In the first option,the system warns the driver whenever the car crosses lane markings by causing the steering wheel to vibrate(振動(dòng)).In the second option,the system helps the car keep pace with other cars while remaining in its current lane.The system is being developed to help relieve blocking on busy roads.
       Several carmakers claim that they'll produce driverless cars within the next decade.But critics aren't so sure,warning that a completely driverless car must be able to make split-second decisions in even the most complex traffic situations.In addition,the car's computer must become smart enough to know when to ask the driver to intervene (介入,干涉) to prevent an accident.
       Full government approval won't happen until driverless cars are proven safe.In the meantime,expect to see carmakers offer ever-smarter features on their new models.
 (Note:Answer the questions or complete the statements in NO MORE THAN TWELVE WORDS)
78.One of the factors that make traffic extremely stressful is thepedestrians appearing out of nowhere/cars pulling out of parking spots/slippery roads due to rain or snow
79.What are the benefits of driverless system?Improved safety and increased efficiency
80.What will happen to a car with the Active Lane Keeping Assist when it crosses lane markings?The steering wheel will vibrate.
81.Driverless cars won't be on the market until they canmake split-second decisions and know when to ask the driver to intervene.

2.Every year some 15,000 animals-mostly mice-are shipped into the UK for research.Some leading scientists are warning that pressure from animal rights activists is reducing the number of animals being brought into Britain for research.All ferry companies and all but two airlines have stopped importing animals intended for research laboratories.
Lord Drayson,who was a minister under the last Labour government,said animal research was"regrettably"necessary and that people would"suffer and die"without it."If we do want to have access to medicines,and I believe that we do-in a survey carried out in the past 10 years more than 87% of the general public have said that they support animal research for medical uses.And so unfortunately we do have to do this."
However,Alistair Currie from People,for the Ethical Treatment of Animals (PETA) said researchers should work harder to come up with alternatives to animal testing."More man 90% of drugs that pass trials in animals fail when they're given to people,"he said.They either prove to be unsafe or simply ineffective."
The BBC's Tom Fielden says animal rights campaigners have been imprisoned for taking direct action against laboratories in the past and more recently have focused on creating bad PR (public relations).He says this has included letter-writhing and web-based campaigns against transport companies,which appear to have had an effect.
But the scientists who depend on the animals for their work have now decided to speak out to try to persuade the government and the transpon companies to stand up to the campaigners.Professor Robin Lovell-Badge,a geneticist at me National Institute for Medical Research (NIMR),told the BBC it was important that scientists were able to import animals,so they could work together with colleagues abroad.Dominic Wells of the Royal Veterinary College (RVC) said,"The problem is that they can't be put in a suitable transport."
63.Now animal rights campaigners are trying to affect importing animals byD.
    A.finding alternatives to animal testing    B.creating bad public relations
    C.taking direct action against labs         D.stopping transport animals to UK
64.According to Lord Drayson,importing animals isA
    A.optional                             B.necessary                     
    C.unreasonable                         D.unconditional
65.Who is against importing animals for research?B
    A.Alistair Currie form PETA.       B.Tom Fielden from the BBC.
    C.Robin Lovell-Badge from the NIMR. D.Dominic Wells from the RVC.
66.Which of the following can be the best title for the passage?A
    A.Activists stopping direct action against imports
    B.Importing animals contributing to medicine
    C.Activists'pressure slowing animal imports
    D.No animal imports,no medical research.

9.People with an impulsive personality refer to those who tend to do things without considering the possible dangers or problems first.According to a new study by researchers at the University of Georgia,such people may be more likely to have food addiction.The study found that people exhibiting impulsive behavior weren't necessarily overweight,but impulsiveness was related to a direct relationship with food,and therefore,less healthy weight.
Food addiction has been compared to addictive drug use.Studies have linked the dopamine (多巴胺) release that occurs after tasting delicious food to the dopamine release that happens when people consume other addictive substances.
Impulsive behavior involves several personality traits (特點(diǎn)).Two of these traits,known as negative urgency and lack of perseverance,were particularly associated with food addiction and high BMI (身體質(zhì)量指數(shù)) during the study.
Negative urgency is characterized by the tendency to behave impulsively when experiencing negative emotions.Some people might drink alcohol or take drugs.For others,it could mean eating to feel better.Lack of perseverance is when a person has a hard time finishing hard or boring tasks.People with a lack of perseverance might have difficulty attempting to change addictive eating behavior,which could also cause obesity.
"Impulsiveness might be one reason why some people eat in an addictive way despite motivation to lose weight,"said Dr.Ashley Gearhardt,a clinical psychologist.He was involved in developing the Yale Food Addiction Scale in aid of those people."We are theorizing that if food addiction is really a thing,then our measure,the Yale Food Addiction Scale,should be related to helping control impulsive action,"said Gearhardt.
Clinical psychologist Dr.James MacKillop,whose lab was conducting the study,believes that therapies used to treat addictive drug behavior could help people who suffer from addictive eating habits.
"Most of the programs for weight loss at this point focus on the most obvious things,which are clearly diet and exercise,"MacKillop said."It seems that managing strong desires to eat would naturally fit in with the skills a person would need to eat healthily."

12.According to Paragraph 1,the result of food addiction isA.
A.less healthy weight  B.motivation to lose weight
C.negative emotions    D.taking alcohol or drugs
13.How does the author introduce the two personality traits in Paragraph 4?D
A.By making comparisons and conclusions. B.By explaining causes and effects.
C.By presenting questions and answers.   D.By giving definitions and examples.
14.What can be inferred about the Yale Food Addiction Scale from the text?B
A.It has been successfully carried out among overweight people.
B.It might help some impulsive people with food addiction to lose weight.
C.It will prove whether food addiction is a problem to impulsive people.
D.It is theoretically a proper treatment for addictive food and drug behavior.
15.Which of the following can be the best title for the text?C
A.Dopamine release caused by food addiction  
B.Food addiction compared to drug use
C.Impulsive personality linked to food addition   
D.Food addiction contributing to obesity.

7.The Focal Point of the"Chinese Liquor Golden Triangle"
In China,there is a saying:a good spirit(wine) is in Sichuan,but the great one is in Yibin.
Yibin,the birthplace of Wuliangye,has a centuries-old tradition of producing great spirits.At the confluence of Jinsha and Min rivers,Yibin is praised as the first city on the source of the Yangtze River.Here,the water is clean,the soil is rich,and the climate is very favorable for brewing good liquor.The blessings of nature and centuries-old liquor brewing traditions gave rise to"The Ten-Mile Liquor City",the main production facility of domestic liquor giant Wuliangye Group Co.Ltd.
Extending across 10 kilometers and dotted with gardens and sculptures,the city attracts domestic and foreign visitors with its famed liquor brewing and related culture.Another attraction is its legendary Ming Dynasty (1368-1644AD) liquor cellars (酒窖,地下儲(chǔ)藏室).
The city has 30,000 large modern brewing tanks that provide an enormous capacity to store liquor.
The high quality of Wuliangye also owes much to its unique brewing techniques and materials.These traditional techniques are included on the list of national intangible(非物質(zhì)的) cultural heritage.
Wuliangye's sales revenues(銷售額)and pre-tax profits accounted for nearly half of the respective (分別的) 59 billion yuan and 12.5 billion yuan generated by Sichuan's provincial liquor industry in 2008.Liquor production by large enterprises in the province was about 1.1 million kiloliters,accounting for 19.6% of the production in the country.
Wuliangye is now investing 300 million yuan in a state-of-the-art quality assurance center (質(zhì)保中心)that has higher standards than national requirements,which will boost the existing quality-control system when it is put into service next year.
With a goal of production value of 100 billion yuan for the year of 2020,Wuliangye is playing a leading role in the development of the liquor industry in the region.A lot of related industries are now building up in the region to create a Chinese Liquor Golden Triangle-the Chinese equivalent (相當(dāng)于)of the French Bordeaux region---that continues to appear on the upper reaches of the Yangtze River.
