1、African wild dogFinding a babysitter while you go out to work is, for example, an inconvenience. For the African wild dog, one of the continent\'s most endangered carnivores （食肉动物), it\'s a matter of life and death. A new research shows that once packs (兽群) fall below a certain size, they are not enough animals to both hunt food and stay at home protecting the young.The African wild dog has declined drastically over the past century. Habitual loss (栖息地的丧失), persecution and unexplained outbreaks of disease have all been blamed. Only 3, 000 to5,000 animals remain, and the species is expected to go extinct within decades if the trend continues.Other large carnivores such as the spotted hyena (鬣狗) face similar pressures, yet are not declining. Now Franck Courchamp of Cambridge University has found a reason why. The dog\'s weakness lies in its social organization.Within each pack of up to 20 adults and pups, only the dominant male and female breed. The remaining animals help raise the pups, cooperating to hunt prey and defend the kill from other carnivores.Because pups can\'t keep up on a hunt, large packs leave an adult behind to protect them from predators (捕猎者), which include lions and hyenas. But leaving a babysitter also carries costs. A smaller hunting party is less able to tackle large prey and to defend the kill. There is also one less stomach in which to carry food back to the den, and one more mouth to feed when they get there.Courchamp investigated this awkward trade-off (权衡) by modeling how the costs of a babysitter change with decreasing pack size. This showed that packs of more than five adults should be able to feed all the pups and still spare a babysitter. But with smaller packs, either the hunting or the babysitting suffers, or the animals have to compensate by increasing the number of hunting excursions which itself carries a cost to the pack.Field observations in Zimbabwe supported the model. Packs of five animals or fewer left pups unguarded more frequently than larger packs did. There was also evidence that when they did leave a babysitter, they were forced to hunt more often.A pack which drops below a critical size becomes caught in a vicious circle (恶性循环), says Courchamp, who is now at Paris-Sud University. "Poor reproduction and low survival further reduces pack size, culminating in (最终造成) failure of the whole pack. " And deaths caused by human activity, says Courchamp, may be what reduce pack numbers to below the sustamable threshold. Mammal ecologist Chris Carbone at London\'s Institute of Zoology agrees. Maintaining the integrity of wild dog packs will be vitalin preserving the species, he says.The dominant female is always left behind to protect the young.【单选题】

4、Geology and Heap(1)The importance of particular metals in the human diet has been realized within the past few decades, and the idea that geology might be related to health has been recognized for a number of elements such as iodine, zinc and selenium. For example, soils with low iodine contents produce crops, and animals deficient in iodine. A lack of iodine in the human diet leads to some serious diseases.(2)The ultimate source of metals within the human body is rocks, which weather into soil, gaining or losing some of their chemical constituents. The crops we eat selectively remove from the soil the elements that they require for growth. The water we drink contains trace elements leached from rock and soil. Thus the geology and geochemistry of the environment have effects on the chemistry and health of plants, animals and people.(3)So far there is no data to suggest that people living on metal-rich soils experience a potential health hazard. The levels of metals within naturally contaminated soils are generally not high enough to cause serious health problems. Living on metal-rich soils does not represent a health risk unless large quantities of soil are digested or metal-rich dust is inhaled. However, small children are particularly exposed to metal-rich topsoil in playgrounds and gardens. They are also the most likely ones to eat potentially dangerous metal-rich soil.(4)Heavy metals are persistent: they do not break down to other chemicals in the environment. Industrially polluted sites usually undergo intensive clean-up and rehabilitation because heavy metals are a health concern once they enter the food chain. Some trace metals are alleged to cause cancer and are also known to cause poisoning(5)In contrast, naturally contaminated soils have not been subject too risk assessment studies and rehabilitation measures, despite the fact that they frequently possess metal concentrations well above those of such polluted by humans and above environmental quality criteria.(6)There is a vital need to understand the potential risks and long-term health effects of living on naturally contaminated soils. Future environmental investigations of naturally polluted soils should concentrate on the potential pathways of metals into the food chain and human body. Geologists should be part of such studies as they can provide the essential background information on rock and soil chemistry as well as the chemical forms of heavy metal pollution.Paragraph 4 ______【单选题】

A.No Evidence to Indicate Bad of Naturally Contaminated Soil

B.Potential Hazards of Human Contaminated Soils

5、Sharing SilenceDeaf teenagers Orlando Chavez and German Resendiz have become friends since kindergarten (幼儿园). Together the two boys, who go to Escondido High School in California, have had the difficult job of learning in schools where the majority of the students can speak and hear.Orlando lost his hearing at the age of one. German was borned deaf, and his parents moved from Mexico to find a school where he could learn sign language. He met Orlando on their first day of kindergarten."We were in a special class with about 25 other deaf kids," German remembers. "Before then, I didn\'t know I was deaf and I was different.""Being young and deaf in regular classes was very hard," signs Orlando. "The other kids didn\'t understand us and we didn\'t understand them. But we\'ve all grown up together, and today, I\'m popular because I\'m deaf. Kids try hard to communicate with me."Some things are very difficult for the two boys. "We can\'t talk on the phone. so if we need help, we can\'t call an emergency service," German signs. "And we can\'t order food in a drive - thru."Despite their difficulties, the two boys have found work putting food in bags at a local supermarket. They got their jobs through a "workability" program designed for teenagers from local schools with different types of learning disabilities.German has worked in the supermarket since August, and Orlando started in November."The other people who work here have been very nice to us," Orlando signs. "They even sign sometimes. At first, we were nervous, but we\'ve learned a lot and we\'re getting better.The opportunity to earn money has been exciting, both boys said. After high school, they hope to attend the National Technical Institute for the deaf in New York.Both boys are happy to ____.【单选题】

6、Women Staying in Mini-Skirts for LongerBritish women are happy nowadays to wear mini-skirts up until the age of40, according to research by Debenhams.Just 20 years ago, few women would dare to wear a mini-skirt. after the age of 33, the store said. "It shows that women now have an increasing confidence in their bodies and are happy to dress accordingly," it added in a statement. "If this trend continues, there\'s no doubt that, within the next decade, women in their mid 40s and early 50s will rightly regard a mini-skirt as an essential part of their everyday wardrobe. "The figures emerged when the store examined the latest age profile of women buying short,36-cm skirts over the past six months. Their results show that it has jumped from an average age of36-years-old at the start of millennium to 40 today. Figures from 1980 showed that on average women stopped buying minis when they reached 33 years old, a figure unchanged from the mid-1960s.The store noted that experts believe that the popularity of intensive gym culture, providing women with well toned bodies for longer may be the reason, The increasing number of British women living on their own may also be a factor.The Debenhams\' study showed that a modern woman\'s love affair with a mini-skirt begins at the age of 14 but that she doesn\'t buy her first one until the age of 16. Instead, she flouts school rules by rolling up the waistband of the school uniform to give the impression of wearing a mini skirt.Skirts get shorter between the ages of 16 and 19, reducing in size from 46 to 36 cm before reaching their shortest, a mere 32 cm, at the age of 23. Skirt length increases slightly between the ages of 23 and 27, rising to 37 cm, possibly due to girls being in their first stable relationship, with no desire to attract attention, the store said.However, it found short skirts suddenly zoom in popularity between the ages of27 and 34, as those early relationships break down, and new relationships are formed. The move into longer skirts begins irreversibly at 40 years old, when 46-cm skirts, still slightly above the knee are the norm. From then on, skirt length increases dramatically, falling below the knee for the very first time since school days at the age of42.We can infer from the second and third paragraph that in 1970s_____.【单选题】

A.a lot of women dared to wear mini-skirts at the age of40

B.most women between 33 and 36 were still happy to wear mini-skirts

D.most women no longer wore mini-skirts when they reach the age of33

正确答案:D

答案解析:第3段说从20世纪60年代开始一直到80年代，调查都显示女性到33岁之后普遍不再购买超短裙。

7、Life at Aichi UniversityI\'m Yamamoto Mika, a 22 years old Japanese girl. I\'d like to invite you to Aichi University so you can understand my life.Our university has a close relationship with China and my department is the only one of its kind in Japan. My courses include the Chinese language, modern Chinese politics and economics. I love Chinese culture and I have been to Tianjin as an exchange student.In Japan, our courses are divided into compulsory, optional and specialized courses. However, we have a flexible schedule. We can choose classes from a wide range of options.Many students finish the compulsory courses in three years so that they can have one year without any classes. They often use this period of time to study abroad, conduct research and travel. Many students even suspend their study for additional study - abroad opportunities,Japanese universities encourage students to choose their own ways of study, so it is quite easy for us to apply for study suspension.Japanese students participate in various kinds of extracurricular (课外的) activities. They attend clubs from elementary schools, so many students have already been accustomed to clubs when they enter university.Our university now has 42 art clubs and 45 sports clubs. The annual University Festival is the grandest carnival (狂欢节) of Japanese universities. In the festival, students promote their clubs and organize various activities. Our university\'s festival attracted about 150,000 people last year. I really like this festival.When we promote our clubs, we cook "tonnjiru", a kind of pork soup, and sell it to other students at the fair.We also go to different places to interview celebrities (名人) who attend our festival as guests. It is a wonderful experience to talk to those stars face to face.Japanese students like to hold parties. We have two kinds of parties. One is the Mochivori party. If you want to attend this party you have to cook something and take it to the party. The organizer buys drinks and snacks.The other kind of party is the Nomikai, which mainly involves alcohol. We drink something called chu - hai, which is a combination of soda and wine. We also drink Japanese sake (日本米酒) and beer. There are parties for many occasions, like welcoming new students, celebrating victories and birthday parties or just for promoting friendship.Many Japanese students finish their compulsory courses in three years because ____.【单选题】

9、A Bad IdeaThink you can walk, drive, take phone calls, e - mail and listen to music at the same time? Well, New York\'s new law says you can\'t. And you\'ll be fined $ 100 if you do so on a New York city street. The law went into force last month, following research and a shocking number of accidents that involved. people using electronic gadgets (小巧机械) when crossing the street.Who\'s to blame? Scientists say that our multitasking (多任务处理) abilities are limited. "We are under the impression that our brain can do more than it often can," says Rene Marois, a neuroscientist (神经科学家) in Tennessee. "But a core limitation is the inability to concentrate on two things at once."The young people are often considered the great multitaskers. However, an Oxford University research suggests this perception is open to question. A group of 18 to 21 years old and a group of 35 to 39 years old were given 90 seconds to translate images into numbers, using a simple code. ____ But when both groups were interrupted by a phone call or an instant message, the older group matched the younger group in speed and accuracy.It is difficult to measure the productivity lost by multitaskers. Jonathan Spira, chief analyst at Basex, a business - research firm, estimates that the cost of interruptions to the American economy is nearly $650 billion a year, The estimate is based on surveys with office workers. The surveys conclude that 28 percent of the workers\' time was spent on interruptions and recovery time before they returned to their main tasks.【单选题】

A.Talking on a cell phone while driving brings you joy anyway.

B.The estimate is based on surveys with office workers.

C.The younger group did 10 percent better when not interrupted.

10、Woman workThough some people have suggested that women should return to housework in order to leave more jobs for men, the idea has been rejected by both women and men in public opinion polls.Lately some union officials have suggested that too many women are employed in types of work more ____ for men and that women should step aside to make way for unemployed young men. They argue that women, especially women in their childbearing years,actually delay economic development and result in productivity, poor quality and inefficiency.To solve the problem, they suggested that working women stay at home while their husbands or brothers were given double wages. They argue that under these circumstances, families would remain their same level of income, and women could run the house and raise children much better,The suggestion, however , has been flatly rejected by 9 0ut of 10 people polled .Some other people have suggested another way called "phased employment" theory. The theory suggests that a woman worker take leave from her job when she is seven months pregnant and stay off the job until her baby reaches the age of 3. It suggested that women on leave receive 75 percent of their normal salary and be allowed to return to work after the three-year period. This will benefit children, women, their families and the society and it definitely seems to be more acceptable than the suggestion that women return to their homes forever.【单选题】

A.available

B.suitable

C.reliable

D.practical

正确答案:B

答案解析:be suitable for：适合，符合上下文。available:可得到的、可利用的；reliable:可信赖的、信得过的；practical:实际的。
