单选题The elements that determine a national foreign policy consist in ______.Athe various grades of oil
Bthe links between oil and foreign policy
Cthe benchmarks that are used to negotiate prices
Dthe general availability and overall price of oil
正确答案： B解析：
该段录音中提到石油产业的细节问题非常复杂，而这些细节对于石油和对外政策之间关系来说无关紧要，因为“…national policy depends only on the general availability and overall price of oil”，因此选项D符合。consist in在于；存在于。
【录音原文】
Oil markets appear more mysterious than they are. The details of the oil business are very complex—the various grades of oil, the complicated contracts used to buy oil and hedge against volatility, and the benchmarks that are used to negotiate prices—but few of those details matter for a discussion of the links between oil and foreign policy. Oil companies care about those details because they are trying to earn a profit on each individual contract, but national policy depends only on the general availability and overall price of oil. -

单选题According to the UN, there are ______Africans under 14 nowadays in Africa.A237 million
B348 million
C400 million
D120 million
正确答案： C解析：
该段录音主要讲述非洲落后的原因之一是人口增长过快，提到1999年非洲14岁以下的孩子有237 million，而现在有348 million，到了2015年这个数字会超过400 million。因此正确答案为B。
【录音原文】
Africa lags partly because its population is growing so rapidly. In rural areas, mothers are giving birth to at least six children on average, doubling the population every generation. As a result, Africa’s top-line numbers are improving more than its ratios. Millions more African children are going to school, but the denominator is also increasing. According to the UN, in 1990 there were 237 million Africans under 14; today, that figure is 348 million, and by 2015 it is expected to top 400 million. -

单选题It can be concluded from the passage that ______.Ait is hopeful to bring solar energy into average households
Bit is feasible to use nuclear energy to run home appliances
Cit is economical to use water to heat houses
Dit is possible to use wind to power machines
正确答案： A解析：
录音中指出通过使用hybrid nanorod polymer composite可以极大降低利用太阳能的成本，虽然目前为止nanorod polymer cells的转换效率只是2%多一点，但是研究者相信效率能得到极大提高，由此可推断太阳能在普通家庭的使用是有望实现的。
【录音原文】
Millions of people around the world would like to heat their homes and run household appliances with solar power. But the cost of doing so puts it out of the question. The first problem is that the cells convert only 10％-15％of the radiation from the sun into energy. The second is that the photovoltaic (PV) material used is a form of silicon that has to be made under high vacuum conditions and heated in special kilns to 1.400℃. That makes photovoltaic solar cells horrendously expensive.
How to bring the high costs down to a more manageable amount? One answer that is attracting attention is to use carbon “nanorods”, superstrong cylinders of carbon atoms that are 75, 000 times thinner than a human hair. If scientists succeed in their efforts, carbon-based solar cells could cost as little as a tenth of the price of today’s silicon-based versions.
By placing the flexible nanorods in a polymer solution, researchers found it could produce a composite material that had the elasticity and pliability of plastic, but capable converting solar rays into electrical energy. Inorganic nanocrystals behave a lot like polymers. For instance, they can be processed while still in the form of a solution. Scientists had been working with plastics as an alternative to conventional solar cells, but found that they did not conduct electricity particularly well.
Compared with the arduous process of fabricating conventional solar cells, making the hybrid nanorod polymer composite would be more like manufacturing cheap plastic laminates. That could solve the cost part of the solar energy equation. But what about the conversion efficiency? So far, the conversion efficiency of nanorod polymer cells has been little more than 2％. However, researchers are confident that the efficiency can be improved considerably. -

【录音原文】
Anxious observers will have to wait until later in the month to confirm which parts of the euro area’s giant economy are losing the most steam. But it is likely that both French consumers and German exporters, the euro area’s twin-stroke engine of growth in the first half of the year, have misfired since. -
第7题：
单选题The local people sometimes kill tourists when ______.Athe tourists are much richer than themselves
Bthe tourists are robbed
Cthe tourists do not enjoy local customs and habits
Dthe tourists resist attempts to rob them
正确答案： A解析：
录音中提到“Seeing tourists who seem to be much richer than themselves，the local inhabitants are often tempted to steal from them. Sometimes tourists resist and get killed…”，意思是：当地居民看到游客比他们有钱便试图去偷去抢，有时如果游客反抗便被杀害。所以D项“当游客反抗企图抢劫他们的行为时”符合原文意思。
【录音原文】
Most countries in the world now welcome tourists because of the money they bring in. Many countries make great efforts to encourage tourism, and many also depend on what they earn from it to keep their economies going.
People who like adventure will even try to visit countries where travel is difficult and costs are high. Companies regularly arrange trips through the Sahara desert, or to Himalayas for whoever enjoys such trips, but the numbers of visitors are small. Most tourists try to choose whichever places have fairly comfortable, cheap hotels, quite good food, reasonable safety, sunny weather and plenty of amusements or unusual things to see. Their choice of a place for a holiday also depends very much on when they can get away；it is not very pleasant to go to a place when it is having its worst weather.
One of the big problems of a nation wishing to attract a lot of tourists is the cost of building hotels for them. Building big hotels swallows up a lot of money, and many of the countries that need the tourists are poor. What they spend on building has to be borrowed produces only chains of ugly hotels wherever there are beauty spots supposed to attract tourists.
Another problem is that more and more big international companies are building hotels all over the world, so that the profits from a hotel often do not stay in the country in which it has been built.
And there is also the question of training staff, teaching them foreign languages, how to cook the kind of food that the foreign tourists expect, and so on. In many countries, special colleges and courses have been set up for this.
Crime can also be a problem. Seeing tourists who seem to be much richer than themselves, the local inhabitants are often tempted to steal from them. Sometimes tourists resist and get killed, and then other tourists refuse to come to the country. -

【录音原文】
The world is going through the biggest wave of mergers and acquisitions ever witnessed. The process sweeps from hyperactive America to Europe and reaches the emerging countries with unsurpassed might. Many in these countries are looking at this process and worrying “won’t the wave of business concentration turn into uncontrollable anti-competitive force?” -

Bhave cost the U.S. Department of Homeland Security more than $ 40 million so far
Care mainly deployed near Washington
Dwork better than they have been expected to
正确答案： B解析：
录音首句便指出“目前为止，美国国土安全部（the U.S. Department of Homeland Security）已经拨给美国各州超过400万美元以对video security systems（视频安全系统）进行投资”，因此选项B为正确答案。
【录音原文】
So far, the U.S. Department of Homeland Security has given American states more than $40 million to invest in video security systems. But in March, the Washington metropolitan police department admitted that the dozens of cameras it has had in place since 9/11 have so far netted zero arrests. What the surveillance cameras can do is help investigators piece together the details of plots after they are attempted, gather forensic evidence and identify suspects—all of which deepens their understanding of how terrorist networks operate. -

正确答案： C解析：
录音最后指出虽然联邦和州政府的官员正在调查美国中西部猴痘病例的原因，但是他们确实知道所有的病人都与被作为宠物养的受感染牧场狗有过直接或亲密的接触，因此选项D有误。
【录音原文】
The first cases of a virus related to smallpox have been reported in the Americas. At least 23 cases of monkeypox had been detected in three Midwestern states—Illinois, Indiana and Wisconsin. Although similar in many ways to smallpox, monkeypox is less infectious and less deadly than its more famous relative. The disease occurs primarily in Central and West Africa. Although state and federal officials are still investigating the cause of the Midwest monkeypox cases, they do know that all the patients had direct or close contact with infected prairie dogs kept as pets. -

BBecause the court fails to convict the tomato-thrower very soon.
CBecause the unemployment benefits are going to be reduced.
DBecause the unemployment benefits are going to be stopped.
正确答案： D解析：
因果关系的找寻和判断。录音中指出“Social democratic politicians have been facing the wrath of the public in recent months especially in the economically depressed east where many people face painful jobless benefit cuts from January 2005”，表明最近几个月社会民主派的政客已饱尝公众愤怒，尤其是在经济衰退的东部地区，因为自2005年7月以来那个地区的失业救济金遭到削减，人们感到痛苦不堪。由此可见，jobless benefit cuts是德国东部地区民众对政客们感到尤其愤怒的原因，对应选项C。 -
第20题：
单选题The best cure for smoking-related diseases is ______.Ato refuse to smoke
Bto improve environmental protection
Cto stop the selling of cigarettes in shops
Dto increase taxation on tobacco
正确答案： A解析：
录音最后一句指出“…smoking prevention is among the most cost-effective of all health interventions”，由此可见防止吸烟是解决所有因吸烟引起的疾病的最好方法，因此选A。
【录音原文】
Tobacco not only kills people, but it also saps national treasuries. Just as there are no safe levels of tobacco consumption, there are no safe investments in tobacco. The economic impact of tobacco has been analyzed in many countries in recent years. Studies from Brazil, China, South Africa and Switzerland complement earlier analyses done in Canada, the United Kingdom and the United States. Their combined message is unequivocal—the alleged economic benefits of tobacco are illusory and misleading.
Most serious analyses of all the economic effects show that a decline in the tobacco industry would not result in less employment. In fact, as employment in the tobacco sector decreases, overall employment may stay the same or even increase. A World Bank study has estimated that the use of tobacco results in a global net loss of US $200 billion per year, with half of these losses occurring in the developing world. This cost does not reflect loss due to reduced quality of life of smokers and their families. The same study also estimated that smoking prevention is among the most cost-effective of all health interventions. -
第21题：
单选题How much loss will the shutdown cause the government in royalties and taxes in a week?AAbout $44.8 million.
BAbout $2.8 million.
CAbout $28 million.
DAbout $4.48 million.
正确答案： C解析：
数字信息的找寻和判断。录音中指出油田的关闭导致每天损失40万桶油，以目前的油价来计算，也就意味着“the state is losing about $6.4 million a day in royalties and taxes”，即“该州每天损失大概$6. 4 million（640万美元），那么一周下来就会损失44. 8 million。因此选项A为正确答案。 -
第22题：
判断题The theory of “Machiavellian mind” is that human intelligence is in a behavioral equivalent of the peacock’s tail.A对
B错
正确答案： 错解析：
关于人类智慧发展的原因，录音中描述了两个理论：“Machiavellian mind”和“mating mind”。在讲到后者时，录音中指出“…the “mating mind”, is that much of human intelligence is about showing off to the opposite sex, in a behavioral equivalent of the peacock’s tail”，因此题干有误。
【录音原文】
Why human intelligence evolved in the first place is controversial. Many researchers feel that it was not so much to deal with the non-human world (e.g., predators and food-gathering) as to deal with other people. One theory, known as the “Machiavellian mind”, is that intelligence is there to analyse, and thus manipulate, the motives of others. Another, known as the “mating mind”, is that much of human intelligence is about showing off to the opposite sex, in a behavioral equivalent of the peacock’s tail. Both could be true. Whether either of these purposes would disappear on an island is moot. -
第23题：
单选题Which of the following is true according to the passage?AThe drive weighed a full ton.
BThe IBM research center planned to make a music player.
CIts 24 spinning disks could store only 5 megabytes of information.
DThe price for renting the RAMAC was $260,000 a year.
正确答案： A解析：
事实细节的找寻和判断。从录音中提到的“The RAMAC, designed in Big Blue’s San Jose, Calif., research center”，可知RAMAC是在Big Blue’s San Jose, Calif., research center 制造的，而非B项提到的IBM research center。此外，C项中的24 spinning disks与录音中its 50 spinning…disks的内容不符。关于租用该设备的价格，录音中提到“to lease it you’d pay about $250,000 a year in today’s dollars”，而选项D则指出租赁价格为$260,000，显然与录音原文不符。A项的内容在录音中直接出现过。
【录音原文】
On September l3, 1956, IBM shipped the first unit of the RAMAC, in other words, Random Access Method of Accounting and Control. The RAMAC, designed in Big Blue’s San Jose, Calif., research center would have made a lousy music player. The drive weighed a full ton, and to lease it you’d pay about $250, 000 a year in today’s dollars. Since it required a separate air compressor to protect the two moving “heads” that read and wrote information, it was noisy. The total amount of information stored in its 50 spinning iron-oxide-coated disks—each of them a pizza-size 24 inches—was 5 megabytes. -

BRisks of developing cancer involved in the use of mobile phones.
CDamage to healthy cells caused by the use of mobile phones.
DThe potential health hazards of mobile phones on humans.
正确答案： C解析：
主旨题。该段录音首先指出科学家们担心手机的使用会影响人类的健康，因为研究表明手机辐射会加速癌细胞数量的增长。接着录音中提到虽然无法从研究结果得出辐射会对人类健康带来直接威胁的结论，但证明了一些科学家认为辐射会损害DNA并摧毁细胞修复系统的观点。录音最后描述了世界卫生组织和英国政府对手机使用持有戒备态度，敦促人们减少使用。由此可知，录音的主要内容是关于手机会给人类带来的潜在危险。因此选项D为正确答案。
