14．Children whose minds wander might have sharper brains，a research suggests．
A study has found that people who appear to be often distracted （走神） have more"working memory"，giving them the ability to hold a lot of information in their heads and control it cleverly．
Children at school need this type of memory on a daily basis for a variety of tasks，such as following teachers'instructions or remembering dictated （听写的） sentences．During the study，volunteers were asked to perform one simple task during which researchers kept asking if their minds were wandering．At the end，volunteers measured their working memory capacity （容量） by their ability to remember a series of letters mixed with simple maths questions．
Daniel Levinson，a professor at the University of Wisconsin-Madison in the United States，said that those with higher working memory capacity reported"more mind wandering during these simple tasks"，but their performance did not suffer．
The results，published online in the journal Psychological Science，appear to confirm former research that found working memory allows humans to deal with multiple thoughts at the same time．
Dr Jonathan Smallwood，of the Max Planck Institute for Human Cognitive and Brain Science in Leipzig，Germany，said，"What this study seems to suggest is that，when surroundings for the task aren't very difficult，people with additional working memory capacity use them effectively to think about other things besides what they're doing．"
Working memory capacity is also associated with general measures of intelligence，such as reading comprehension and IQ scores．Dr Smallwood added："Our results suggest the sorts of planning that people do quite often in daily life-when they are on the bus，when they are cycling to work，when they are in the shower-are probably supported by working memory．"

28．During the study，the researchers asked the volunteers toD．
A．solve some difficult math's problems
B．retell some dictated sentences
C．follow the teacher's instructions
D．carry out one simple task
29．The underlined word"suffer"in the fourth paragraph probably meansA．
A．become worse B．settle down C．experience pain D．run out
30．According to the study，working memoryC．
A．prevents people from remembering dictated sentences
B．causes people's minds to wander more easily
C．allows people to consider more things at the same time
D．leads to people's worse performance during work
31．What's the text mainly about？B
A．How the working memory works in the daily life．
B．Wandering minds might have brighter brains．
C．Why people's minds wander while working．
D．Working ability can be improved by wandering minds．

After 10seasons wearing the No 8on his back，Kobe Bryant will become No 24next season．The reason for the surprising decision by the Los Angeles Lakers super guard last week has become a hot topic for debate．
Bryant wore No 24when he was in early high school，but he changed to No 33in his senior year．He switched to No 8when he was selected by the Lakers in 1996，and has not been changed since．
Bryant has refused to explain the decision until the end of the play-offs．So guessing Bryant's motive has become a popular game among NBA fans and newspaper columnists．
There are all kinds of speculations．Many say that Bryant wants to leave the past behind and have a fresh start．He has often been criticized for playing to benefit himself and not the team as a whole．Others say that he may be trying to compare himself to Michael Jordan．Jordan was famous for his No 23jersey．Some，such as NBC Sport columnist Michael Ventre，argue that it is"all about money"．Bryant will make more money by selling new jerseys to his fans．
Some speculations are more about fun．For example，there is an opinion that Kobe is actually just a diehard fan of the popular TV drama"24"．
All this talk has turned the number change into a major issue．It seems that there is a lot of fuss over something that should be pretty simple．
Jersey numbers have their own special significance in American sports，especially basketball．Players choose their number when they join a team and they usually stick with that number for the rest of their career．When a great player retires，his team will honor him by retiring his number．
To some extent，the jersey is the player，and the player is the jersey．Thus，when you see the famous No 23for the Chicago Bulls，you immediately think about Michael Jordan．A No 32Miami Heats jersey recalls the image of Shaquille O'Neal，and the Houston Rockets'No 11belongs only to Yao Ming．
Lots of stories are behind players'jersey number selections．Jordan said that he chose No 23because it was roughly half of 45．Jordan's elder brother wore the No 45in college．Yao Ming once revealed that the No 11stands for two people in love-meaning him and his girlfriend Ye Li．

78．Which team has Bryant played for？A
A．The Los Angeles Lakers．
B．The Houston rockets．
C．The Chicago Bulls
D．The Miami Heats．
79．When did Bryant start to wear No.8？A

B．He wants to compare himself to Jordan．
C．He wants to earn more money．
D．He wants to show that he is a man of great importance．
81．Why did Jordan choose No.23？C
A．Because that number would make him famous．
B．Because that number would make his fans miss him．

12．How can a creature weighing over 5tons and normally taking 150kilograms food and 120liters of water per day survive in a desert environment？
In the southwest African country of Namibia，and the Sahara lands of Mali further north，the desert elephant does just that
Although not regarded as a separate species from the African elephant，the desert cousin differs in many ways．Their bodies are smaller，to absorb less heat，and their feet are larger for easier walking across sandy surfaces．They are taller to reach higher branches．They have shorter tusks，and most importantly，longer trunks to dig for water in riverbeds
Desert elephants can travel over 70kilometers in search for feeding grounds and water holes，and have a larger group of families．They drink only 3-4days，and can store water in a"bag"at the back of their throat，which is only used when badly needed．Dersert elephants are careful feeders------they seldom root up trees and break fewer branches，and thus maintain what little food sources are available．Young elephants may even eat the dung（粪便）of the female leader of a group when facing food shortage．
During drought they are unlikely to give birth to their young but with good rains the birthrate will increase greatly．Desert elephants have sand baths，sometimes adding their own urine （尿） to make them muddy!
As we continue to overheat our weak planet，it can only be hoped that other animal species will adapt（调整．适应） as extraordinarily well to change as the desert elephant．

8．A new study finds that our brains are wired to make music-color connections depending on how the music makes us feel．Mozart's"Flute Concerto No.1in G Major"is most often associated with bright yellow and orange，whereas his"Requiem in D Minor"is linked to bluish gray，the findings revealed．
US researchers from the University of California，Berkeley，enlisted nearly 100subjects for a study on music and color．With 37colors，the UC Berkeley study found that people tend to pair faster-paced music in a major key with lighter，more vivid，yellow colors，whereas slower-paced music in a minor key is more likely to be teamed up with darker，grayer，bluer colors．
"Surprisingly，we can predict with 95percent accuracy how happy or sad the colors people pick will be based on how happy or sad the music is that they are listening to，"said lead author and UC Berkeley vision scientist Stephen Palmer．
In three experiments，the subjects listened to 18classical music pieces that varied in pace （slow，medium，fast） and in major VS minor keys．In the first experiment，participants were asked to pick five of the 37colors that best matched the music to which they were listening．Separately，they rated each piece of music on a scale of happy to sad，strong to weak，lively to dull，and calm to angry．
Next，the research team plans to study particiapants in Turkey where traditional music employs a wider range of scales than just major and minor．"We know that in Mexico and the US the responses are very similar，"Palmer said．"But we don't yet know about China or Turkey．"

8．What can we know about Mozart's"Flute Concerto No.1G Major"？A
A．It is fast in pace．

A．There are colors that do not match any music．
B．People tend to connect happy colors to slow-paced music
C．There is a one-to-one connection between music and color．
D．People nearly do the same in picking colors for different music．
10．How did the researchers do the research？C
A．By making predictions．
B．By researching journals．
C．By conducting experiments．
D．By studying famous musicians．
11．According to the text，the research mainly deals withB

7．Taj Mahal，Agra，India
As many as 28different varieties of precious stones were used to decorate the outside of the Taj Mahal．Construction took around 20years．The building，which was made from white marble from the quarries（采石场） of Rajasthan，appears pink in the morning，white in the day and golden in the moonlight．
Akashi Kaikyo Bridge，Akashi Strait，Japan
It took 10years to construct the Akashi Kaikyo Bridge．It connects the city of Kobe，on Japan's mainland，with Iwaya on Awaji Island．Before it opened，the only way to get between the two cities was by ferry．However，the waterway was at the mercy of severe storms and when two ferries overturned in 1955，killing 168people，public anger convinced the government of the need for a bridge．It's the longest suspension bridge in the world，with a length of 1，991meters．
Panama Canal，Panama
More than 4.5million cubic yards of concrete were used in the construction of this canal's locks and dams．The Panama Canal is a 47-mile long waterway that connects the Atlantic and Pacific Oceans．The earth and rubble dug to make way for it was enough to bury Manhattan to a depth of four meters．A series of locks allows ships to pass through the water．Each lock door weighs 750tons and each lock fills with 52million gallons of water to accommodate the 15，000ships that use the canal every year．
Grand Canyon Skywalk，Arizona
The Skywalk's foundation is strong enough to support 71million pounds，Located 1，219meters above the Colorado River，the Grand Canyon's Sky Walk consists of one million pounds of steel and 83，000pounds of glass．It was the creation of Las Vegas businessman David Jin，who approached the Hualapai Tribe with the idea of a glass walkway over the Grand Canyon in 1996．The Sky walk was assembled on site．
