Recordings of angry bees are enough to send big, tough African elephants running away, a new study says. Beehives (蜂窩)-either recorded or real-may even prevent elephants from damaging farmer's crops.
In 2002, scientist Lucy King and her team found that elephants avoid certain trees with bees living in them. Today,  Lucy wants to see if African honeybees might discourage elephants from eating crops. But before she asked farmer to go to the trouble of setting up beehives on their farms, she needed to find out if the bees would scare elephants away.
Lucy found a wild beehive inside a tree in northern Kenya and set up a recorder. Then she threw a stone into the beehive, which burst into life. Lucy and her assistant hid in their car until the angry bees had calmed down. Next,Lucy searched out elephant families in Samburu National Reserve in northern Kenya and put a speaker in a close to each family.
From a distance, Lucy switched on the pre-recorded sound of angry bees while at the same time recording the elephants with a video camera. Half the elephant groups left the area within ten seconds. Out of a total of 17 groups, only one group ignored the sound of the angry bees. Lucy reported that all the young elephants immediately ran to their mothers to hide under them. When Lucy Played the sound of a waterfall (瀑布) instead of the angry bees to many of the same elephant families, the animals were undisturbed. Even after four minutes, most of the groups stayed in one place.
Lucy is now studying whether the elephants will continue to avoid the sound of angry bees after hearing it several times. She hasn't tested enough groups yet to know, but her initial (最初的) results were promising enough to begin trials with farmers. She has now begun placing speakers in the fields to see if elephants are frightened away.
小題1:We know from the passage that elephants may be frightened of         .
A.loud noisesB.some crops
C.video camerasD.a(chǎn)ngry bees
小題2:As mentioned in the passage, Lucy
A.works by herself in Africa
B.needs to test more elephant groups
C.has stopped elephants eating crops
D.has got farmers to set up beehives on their farms
小題3:Why did Lucy throw a stone into a wild beehive?
A.To record the sound of bees.
B.To make a video of elephants.
C.To see if elephants would run away.
D.To find out more about the behavior of bees.
小題4:Which of the following is true according to the passage?
A.Young elephants ignore African honeybees.
B.Waterfalls can make elephants stay in one place.
C.Elephants do not go near trees with bees living in them.
D.Farmers do not allow Lucy to conduct tests in their fields.

小題1:D
小題2:B
小題3:A
小題4:C

試題分析:一項最新的研究表明大象會害怕蜜蜂,為了讓農(nóng)民利用蜜蜂的聲音防止大象破壞莊稼,Lucy做了實驗,實驗表明大象對于蜜蜂的聲音是畏懼的,但是為了更有效的證明它的效果,Lucy還要進一步進行研究。
小題1:細節(jié)題:根據(jù)文章第一段的第一個句子:Recordings of angry bees are enough to send big, tough African elephants running away, a new study says.可知大象可能害怕憤怒的蜜蜂的聲音。選D
小題2:細節(jié)題:根據(jù)文章最后一段的第二行的句子:She hasn't tested enough groups yet to know, but her initial (最初的) results were promising enough to begin trials with farmers.可知Lucy需要檢測更多的大象群,所以選B
小題3:細節(jié)題:根據(jù)文章第三段的句子:Lucy found a wild beehive inside a tree in northern Kenya and set up a recorder. Then she threw a stone into the beehive, which burst into life.可知Lucy向野生蜂窩扔石頭,是讓它們發(fā)瘋從而記錄下蜜蜂的聲音,所以選A
小題4:細節(jié)題:根據(jù)文章第二段的第一句:In 2002, scientist Lucy King and her team found that elephants avoid certain trees with bees living in them.可知大象不會靠近有蜜蜂的樹,根據(jù)倒數(shù)第二段的句子:Lucy reported that all the young elephants immediately ran to their mothers to hide under them. 可知小象也害怕蜜蜂,根據(jù)When Lucy Played the sound of a waterfall (瀑布) instead of the angry bees to many of the same elephant families, the animals were undisturbed. Even after four minutes, most of the groups stayed in one place.可知是瀑布的聲音讓大象呆在同樣的地方,不是瀑布,而文章也沒有說農(nóng)民不讓Lucy在他們的田地做實驗。所以選C。

An alcohol breath test (ABT) is often used by the police to find out whether a person is drunk while driving.In the United States,the legal blood alcohol limit is 0.08% for people aged 21 years or older,while people under 21 are not allowed to drive a car with any level of alcohol in their body.A “positive” test result,a result over the legal limit,allows the police to arrest the driver.However,many people who tested positive on the test have claimed that they only drank a “non­alcoholic” energy drink.Can one of these energy drinks really cause someone to test positive on an ABT?Researchers in Missouri set up an experiment to find out.
First,the amount of alcohol in 27 different popular energy drinks was measured.All but one had an alcohol level greater than 0.005%.In nine of the 27 drinks,the alcohol level was at least 0.096%.The scientists then investigated the possibility that these small levels of alcohol could be discovered by an ABT.They asked test subjects to drink a full can or bottle of an energy drink and then gave each subject an ABT one minute and 15 minutes after the drink was finished.
For 11 of the 27 energy drinks,the ABT did find the presence of alcohol if the test was given within one minute after the drink was taken.However,alcohol could not be discovered for any of the drinks if the test was given 15 minutes after the drink was consumed.This shows that when the test is taken plays an important role in the test result.The sooner the test is conducted after the consumption of these drinks,the more likely a positive alcohol reading will be obtained.
小題1:What is the legal alcohol level for a 20­year­old driver in the US?
A.0.000%. B.0.005%.
C.0.080%. D.0.096%.

NEW YORK (Reuters Health)—Kids who eat better perform better in school, a new study of Nova Scotia fifth?graders confirms.
Students who ate an adequate amount of fruit,vegetables,protein,fiber and other components of a healthy diet were significantly less likely to fail a literacy test,Dr.Paul J.Veugelers of the University of Alberta in Edmonton and colleagues found.
While a healthy diet is generally assumed to be important for good school performance, there has actually been little research on this topic, Veugelers and his colleagues note.To investigate,they looked at 4, 589 fifth?graders participating in the Children's Lifestyle and School?performance Study, 875 (19.1 percent) of whom had failed an elementary literacy assessment.
The better a student's eating habits based on several measures of diet quality,including adequacy and variety, the less likely he or she was to have failed the test, the researchers found,even after they adjusted the data for the effects of parental income and education, school and sex.Eating plenty of fruit and vegetables, and getting fewer calories from fat, was also associated with a lower risk of failing the test.
To date, Veugelers and his team say, most research on diet and school performance has focused on the importance of eating breakfast, as well as the ill effects of hunger and malnutrition(營養(yǎng)不良).
“This study extends current knowledge in this area by demonstrating the independent importance of overall diet quality to academic performance.We should not only realize the importance of children's nutrition at breakfast but also that throughout the day,” the researchers conclude.
Another research from the UK is suggesting that children's diets in the pre?school years affects how they perform at school later on.The researchers from the Institute of Education, at the University of London say in fact that what children were eating in those days before primary school has more of an effect than the chicken nuggets(塊) they ate at lunchtime.The researchers say they have found that children who ate a diet of “junk food” at the age of three, made less progress in school between the ages of six and ten.They say children's diet at later ages appears to have less impact on their school attainment.
小題1:.According to Dr.Paul J.Veugelers, students who have a healthy diet________.
A.a(chǎn)re more likely to fail in their school performance
B.definitely can perform better in their school work
C.usually have more of fat and less of fruit and vegetables
D.tend to perform better in their school work
小題2:.It can be implied from the passage that________.
A.little research has been done on the importance of breakfast
B.most students participating in the research failed the test
C.the adequacy and variety of foods can mean better school performance
D.eating more chicken nuggets leads to good school performance
小題3:.The underlined word “l(fā)iteracy” (in Para.2) probably refers to ________.
A.the ability to read and write
B.a(chǎn) guessing game
C.the art of painting
D.the ability to handle practical task

A.Children should have more“junk food”at lunch time.
B.Pre?school diets can have more impact on children's school work.
C.A child who often has“junk food”at 3 is bound to fail in school work.
D.The older a child is,the more impact of what he eats has on school work.

Research has shown that two-thirds of human conversation is taken up not with discussion of the cultural or political problems of the day, not heated debates about films we've just watched or books we've just finished reading, but plain and simple ____.
Language is our greatest treasure as a species, and what do we ____ do with it? We gossip. About others' behaviour and private lives, such as who's doing what with whom, who's in and who's out-and why; how to deal with difficult ____ situations involving children, lovers, and colleagues.
So why are we keen on gossiping? Are we just natural ____, of both time and words? Or do we talk a lot about nothing in particular simply to avoid facing up to the really important issues of life? It's not the case according to Professor Robin Dunbar. In fact, in his latest book, Grooming, Gossip and the Evolution of Language, the psychologist says gossip is one of these really____issues.
Dunbar ____ the traditional view that language was developed by the men at the early stage of social development in order to organize their manly hunting activities more effectively, or even to promote the exchange of poetic stories about their origins and the supernatural. Instead he suggests that language evolved among women. We don't spend two-thirds of our time gossiping just because we can talk, argues Dunbar—____, he goes on to say, language evolved specifically to allow us to gossip.
Dunbar arrived at his cheery theory by studying the ____ of the higher primates(靈長類動物)like monkeys. By means of grooming--cleaning the fur by brushing it, monkeys form groups with other individuals on whom they can rely for support in the event of some kind of conflict within the group or____ from outside it.
As we human beings evolve from a particular branch of the primate family, Dunbar ____ that at one time in our history we did much the same. Grouping together made sense because the bigger the group, the greater the ____ it provided; on the other hand, the bigger the group, the greater the stresses of living close to others. Grooming helped to ____ the pressure and calm everybody down.
But as the groups got bigger and bigger, the amount of time spent in grooming activities also had to be ____ to maintain its effectiveness. Clearly, a more ____ kind of grooming was needed, and thus language evolved as a kind of vocal(有聲的)grooming which allowed humans to develop relationship with ever-larger groups by exchanging information over a wider network of individuals than would be possible by one-to-one ____ contact.
小題1:
A.claimB.descriptionC.gossipD.language
小題2:
A.occasionallyB.habituallyC.independentlyD.originally
小題3:

小題8:
A.motivationB.a(chǎn)ppearanceC.emotionD.behaviour
小題9:
A.a(chǎn)ttackB.contactC.inspectionD.a(chǎn)ssistance

The behaviour of a building’s users may be at least as important as its design when it comes to energy use, according to new research from the UK Energy Research Centre (UKERC). The UK promises to reduce its carbon emissions (排放)by 80 percent by 2050, part of which will be achieved by all new homes being zero-carbon by 2016. But this report shows that sustainable building design on its own — though extremely important- is not enough to achieve such reductions: the behaviour of the people using the building has to change too.
The study suggests that the ways that people use and live in their homes have been largely ignored by existing efforts to improve energy efficiency (效率),which instead focus on architectural and technological developments.
‘Technology is going to assist but it is not going to do everything,’explains Katy Janda, a UKERC senior researcher,‘consumption patterns of building users can defeat the most careful design. ’In other words,old habits die hard, even in the best-designed eco-home.
Another part of the problem is information. Households and bill-payers don’t have the knowledge they need to change their energy-use habits. Without specific information,it’s hard to estimate the costs and benefits of making different choices. Feedback (反饋) facilities, like smart meters and energy monitors,could help bridge this information gap by helping people see how changing their behaviour directly affects their energy use; some studies have shown that households can achieve up to 15 percent energy savings using smart meters.
Social science research has added a further dimension (方面),suggesting that individuals’behaviour in the home can be personal and cannot be predicted 一 whether people throw open their windows rather than turn down the thermostat (恒溫器) , for example.
Janda argues that education is the key. She calls for a focused programme to teach people about buildings and their own behaviour in them.
小題1:As to energy use, the new research from UKERC stresses the importance of________.
A. zero-carbon homesB.the behaviour of building users
C. sustainable building designD.the reduction of carbon emissions
小題2:The underlined word “which” in Paragraph 2 refers to”________.”
A.the waysB.their homes
C. developmentsD.existing efforts
小題3:What are Katy Janda’s words mainly about?
A. The importance of changing building users, habits.
B. The necessity of making a careful building design.
C. The variety of consumption patterns of building users.
D. The role of technology in improving energy efficiency.
小題4:The information gap in energy use _______.
A. can be bridged by feedback facilities
B. affects the study on energy monitors
C. brings about problems for smart meters
D. will be caused by building users’ old habits
小題5:What does the dimension added by social science research suggest?
A. The social science research is to be furthered.
B. The education programme is under discussion.
C. The behaviour of building users is unpredictable.
D. The behaviour preference of building users is similar.

Technology and the present generation of kids go hand in hand. Taking advantage of this factor, Lim Hojoon, the designer from South Korea, has come up with an educational gadget (小裝置) especially for children. 
Kidget, as the name suggests, is a combination of two words – kid and gadget. This kid-friendly gadget has various uses. When your child is in a mood to read, it takes the form of a storybook. When the mood is to draw and color this wonder gadget turns into a perfect canvas (畫布). Your child can freely give color to all his/her imaginations. Should he or she wish to have some fun, see this device change into a musical instrument. You too would enjoy doing activities with your loved one using this gadget. This touch screen device will definitely prove to be an ideal friend.
As many parents agree, in this age of technological advancements it is much easier to introduce children to new gadgets than adults. While many adults refrain (克制) from trying out something new, kids are more than prepared to take the leap. Keeping this fact in mind, Kidget is the perfect gift for the child of the 21st century. You will be surprised to see how fast your little one gets acquainted with the device. You might even find yourself lagging (落后) behind at times.
Kidget has another hidden advantage. It helps take the load off young shoulders. With three things rolled into one, a child has much less books, stationary items and related goods to carry. It comes with a promise to make life simpler for kids. Not only is it simple to use but also easy to carry along. The stylish protective case comes with a belt attached to it. Children up to 14 years of age, the targeted audience, enjoy the freedom that comes with it.
