Sylvester is keeping track of the distortions, and he already has quite a long list. He says that all housewives seem to live in lovely homes, dress beautifully, and love their household chores. They smile and boast about floor waxes and proudly display their dirty laundry, dusty tabletops, and filthy ovens. In addition, he has never seen men doing housework. Sylvester thinks that this view of family life is filled with distortions.I am keeping track of the people who appear in the advertisements. I have found handsome men courting the All-American Girl, and they are always recommending brand X toothpaste or brand Y cologne. I see teenagers and children surrounded by their friends, having wonderful times at parties and at school, and they are usually enjoying large harmonious family gatherings. I think that these advertisements are also filled with fantasy.Sylvester and I have concluded that much of American life is pictured unrealistically in commercials. Teenagers do not always have fun at parties, and very few people love doing chores. People do have problems, but few of these are ever shown in commercials. Instead, we watch Cinderella (灰姑娘) discover a miracle floor wax, finish the kitchen chores, and waltz off to the ball. Our heads are filled with these fantasies, and they also suggest that, for any problem, brand Z will provide the instant cure. Sylvester and I will have very few facts and a lot of fantasy to write about in our research reports.

Six Potential Brain Benefits of Bilingual Education
A) Brains，brains，brains. People are fascinated by brain research. And yet it can be hard to point to places where our education system is really making use of the latest neuroscience(神经科学) findings.But there is one happy link where research is meeting practice: bilingual(双语的)education.“In thelast 20 years or so，there's been a virtual explosion of research on bilingualism,”says Judith Kroll，aprofessor at the University of California，Riverside.
B)Again and again，researchers have found，“ bilingualism is an experience that shapes our brain for life,”in the words of Gigi Luk，an associate professor at Harvard's Graduate School of Education. Atthe same time，one of the hottest trends in public schooling is what's often called dual-language or two-way immersion programs.
C)Traditional programs for English-language learners，or ELLs，focus on assimilating students into
English as quickly as possible. Dual-language classrooms，by contrast，provide instruction acrosssubjects to both English natives and English learners，in both English and a target languagc. The goal isfunctional bilingualism and biliteracy for all students by middle school. New York City，NorthCarolina，Delaware，Utah，Oregon and Washington state are among the places expanding dual-language classrooms.
D)The trend flies in the face of some of the culture wars of two decades ago，when advocates insisted on “English first”education.Most famously，California passed Proposition 227 in 1998. It was intendedto sharply reduce the amount of time that English-language learners spent in bilingual settings.Proposition 58，passed by California voters on November 8，largely reversed that decision，paving theway for a huge expansion of bilingual education in the state that has the largest population of English-language learners.
E) Some of the insistence on English-first was founded on research produced decades ago，in which bilingual students underperformed monolingual(单语的)English speakers and had lower IQ scores.Today's scholars，like Ellen Bialystok at York University in Toronto，say that research was “deeplyflawed.”“Earlier research looked at socially disadvantaged groups,”agrees Antonella Sorace at theUniversity of Edinburgh in Scotland.“This has been completely contradicted by recent rescarch”thatcompares groups more similar to each other.
F) So what does recent research say about the potential benefits of bilingual education？ It turns out that, in many ways，the real trick to speaking two languages consists in managing not to speak one of thoselanguages at a given moment—which is fundamentally a feat of paying attention. Saying “Goodbye”tomom and then“Guten tag”to your teacher，or managing to ask for a crayola roja instead of a redcrayon(蜡笔)，requires skills called “inhibition”and“task switching.”These skills are subsets of anability called executive function.
G) People who speak two languages often outperform. monolinguals on general measures of executive function.“Bilinguals can pay focused attention without being distracted and also improve in the abilityto switch from one task to another,”says Sorace.
H) Do these same advantages benefit a child who begins learning a second language in kindergarten instead of as a baby？ We don't yet know.Patterns of language learning and language use are complex. ButGigi Luk at Harvard cites at least one brain-imaging study on adolescents that shows similar changes inbrain structure when compared with those who are bilingual from birth，even when they didn't beginpracticing a second language in earnest before late childhood.
l) Young children being raised bilingual have to follow social cues to figure out which language to use with which person and in what setting.As a result，says Sorace，bilingual children as young as age 3 havedemonstrated a head start on tests of perspective-taking and theory of mind—both of which arefundamental social and emotional skills.
J) About 10 percent of students in the Portland，Oregon public schools are assigned by lottery to dual-language classrooms that offer instruction in Spanish，Japanese or Mandarin，alongside English.Jennifer Steele at American University conducted a four-year，randomized trial and found that thesedual-language students outperformed their peers in English-reading skills by a full school-year's worthof learning by the end of middle school. Because the effects are found in reading，not in math orscience where there were few differences，Steele suggests that learning two languages makes studentsmore aware of how language works in general.
K) The research of Gigi Luk at Harvard offers a slightly different explanation. She has recently done a small study looking at a group of 100 fourth-graders in Massachusetts who had similar reading scores ona standard test，but very different language experiences.Some were foreign-language dominant andothers were English natives.Here's what's interesting.The students who were dominant in a foreignlanguage weren't yet comfortably bilingual;they were just starting to learn English.Therefore，bydefinition，they had a much weaker English vocabulary than the native speakers. Yet they were just asgood at interpreting a text.“This is very surprising,”Luk says.“ You would expect the readingcomprehension performance to mirror the vocabulary—it's a cornerstonc of comprehension.”
L) How did the foreign-language dominant speakers manage this feat？ Well，Luk found，they also scored higher on tests of executive functioning.So，even though they didn't have huge mental dictionaries todraw on，they may have been great puzzle-solvers，taking into account higher-level concepts such aswhether a single sentence made sense within an overall story line. They got to the same results as themonolinguals，by a different path.
M)American public school classrooms as a whole are becoming more segregated by race and class.Dual-language programs can be an exception.Because they are composed of native English speakersdeliberately placed together with recent immigrants，they tend to be more ethnically and economicallybalanced. And therc is some evidence that this helps kids of all backgrounds gain comfort withdiversity and different cultures.
N) Several of the researchers also pointed out that，in bilingual education，non-English-dominant students and their families tend to feel that their home language is heard and valued，compared with aclassroom where the home language is left at the door in favor of English. This can improve students'sense of belonging and increase parents’ involvement in their children's education，including behaviorslike reading to children.“Many parents fear their language is an obstacle，a problem，and if theyabandon it their child will integrate better,”says Antonella Sorace of the University of Edinburgh.“We tell them they're not doing their child a favor by giving up their language.”
O)One theme that was striking in speaking to all these researchers was just how strongly they advocated for dual-language classrooms.Thomas and Collier have advised many school systems on how to expandtheir dual-language programs，and Sorace runs“Bilingualism Matters,”an international network ofresearchers who promote bilingual education projects. This type of advocacy among scientists isunusual;even more so because the "bilingual advantage hypothesis”is being challenged once again.
P) Areview of studies published last year found that cognitive advantages failed to appear in 83 percent of published studics，though in a separate analysis，the sum of effects was still significantly positive.Onepotential explanation offered by the researchers is that advantages that are measurable in the veryyoung and very old tend to fade when testing young adults at the peak of their cognitive powers.And,they countered that no negative effects of bilingual education have been found. So，even if theadvantagcs are small，they are still worth it. Not to mention one obvious，outstanding fact:"Bilingualchildren can speak two languages!”
36. A study found that there are similar changes in brain structure between those who are bilingual from birth and those who start learning a second language later.
37. Unlike traditional monolingual programs，bilingual classrooms aim at developing students’ ability touse two languages by middle school.

The suggestion that bees were not pulling their weight met with skepticism from British beekeepers.Glyn Davies，the President of the British Beekeepers Association，said that bees were not lazy but efficient，“At any particular stage in its energy by doing nothing.Each bee has a unit of life energy and the faster it works，the faster it dies.They are being very wise and perhaps humans should try to follow their example instead of running about like headless chickens.”
The idea of the busy bee is several thousand years old.One current author who has nothing but admiration for the bee is Paul Theroux，the novelist and part-time beekeeper.“I have never seen a bee sleeping.My bees never stop working，”he said.Mr.
Theroux added that Prof.Menzel’s research could have been affected by his national origins.“Perhaps in comparison to the German rate of work，the bee does look lazy，”he said.
Few people think that the busy bee idea will go away，despite the efforts of Prof.Menzel.It seems absurd to apply the word“lazy”to a colony of creatures capable of producing something so extraordinary as honeycomb.The truth is that bees give us an inferiority complex that is not entirely unjustified.In fact，the worship of bees seems to be undergoing a renaissance.IBM recently ran a series of ads drawing on the“waggle dance”of bees，telling businessmen to“make your business waggle.”

Countries Rush for Upper Hand in Antarctica
A)On a glacier-filled island with fjords (峡湾) and elephant seals，Russia has built Antarctica's first
Orthodox church on a hill overlooking its research base. Less than an hour away by snow mobile, Chinese lab ourers have updated the Great Wall Station，a vital part of China's plan to operate five bases on Antarctica，complete with an indoor badminton court and sleeping quarters for 150 people.Not to be outdone，India's futuristic new Bharathi base，built on stilts(桩子)using 134 interlockingshipping containers，resembles a spaceship. Turkey and Iran have announced plans to build bases，too.
B)More than a century has passed since explorers raced to plant their flags at the bottom of the world,and for decades to come this continent is supposed to be protected as a scientific preserve，shieldedfrom intrusions like military activities and mining.But an array of countries are rushing to assertgreater influence here，with an eye not just towards the day those protective treaties expire，but alsofor the strategic and commercial opportunities that already exist.
C)The newer players are stepping into what they view as a treasure house of resources.Some of the ventures focus on the Antarctic resources that are already up for grabs，like abundant sea life. SouthKorea，which operates state-of-the-art bases here，is increasing its fishing of krill (磷虾)，found inabundance in the Southern Ocean，while Russia recently frustrated efforts to create one of the world'slargest occan sanctuaries herc.
D) Some scientists are examining the potential for harvesting icebergs from Antarctica，which is estimatedto have the biggest reserves of fresh water on the planet. Nations are also pressing ahead with spaceresearch and satellite projects to expand their global navigation abilities.
E) Building on a Soviet-era foothold，Russia is expanding its monitoring stations for Glonass，its version of
the Global Positioning System (GPS). At least three Russian stations are already operating in Antarctica，part of its effort to challenge the dominance of the American GPS，and new stations are planned for sites like the Russian base，in the shadow of the Orthodox Church of the Holy 'Trinity.F) Elsewhere in Antarctica，Russian researchers boast of their recent discovery of a freshwater reserve
the size of Lake Ontario after drilling through miles of solid ice.“You can see that we're here tostay,”said Vladimir Cheberdak，57，chief of the Bellingshausen Station，as he sipped tea under aportrait of Fabian Gottlieb von Bellingshausen，a high-ranking officer in the Imperial Russian Navywho explored the Antarctic coast in 1820.
G)Antarctica's mineral，oil and gas wealth are a longer-term prize. The treaty banning mining here，
shielding coveted (令人垂涎的)reserves of iron ore，coal and chromium，comes up for reviewin 2048. Researchers recently found kimberlite (金伯利岩)deposits hinting at the existence ofdiamonds. And while assessments vary widely，geologists estimate that Antarctica holds at least36 billion barrels of oil and natural gas.
H) Beyond the Antarctic treaties，huge obstacles persist to tapping these resources，like drifting icebergs that could jeopardise offshore platforms. Then there is Antarctica's remoteness，with some mineraldeposits found in windswept locations on a continent that is larger than Europe and where wintertemperatures hover around minus 55 degrees Celsius.
I) But advances in technology might make Antarctica a lot more accessible three decades from now.And even before then，scholars warn，the demand for resources in an energy-hungry world could raisepressure to renegotiatce Antarctica's treaties，possibly allowing more commercial endeavours here wellbefore the prohibitions against them expire. The research stations on King George Island offer aglimpse into the long game on this ice-blanketed continent as nations assert themselves，eroding thesway long held by countries like the United States，Britain，Australia and New Zealand.
J) Being stationed in Antarctica involves adapting to life on the planet's driest，windiest and coldest continent，yet each nation manages to make itself at home. Bearded Russian priests offer regularservices at the Orthodox church for the 16 or so Russian speakers who spend the winter at the base,largely polar scientists in fields like glaciology and meteorology. Their number climbs to about 40 inthe warmer summer months. China has arguably the fastest-growing operations in Antarctica. Itopened its fourth station last year and is pressing ahead with plans to build a fifth. It is building itssecond ice-breaking ship and setting up research drilling operations on an ice dome 13,422 feet abovesea level that is one of the planet's coldest places. Chinese officials say the expansion in Antarcticaprioritises scientific research，but they also acknowledge that concerns about“ resource security"influence their moves.
K) China's newly renovated Great Wall Station on King Gcorge Island makes the Russian and Chilean bases here seem outdated.“We do weather monitoring here and other research,”Ning Xu，53，thechief of the Chinese base，said over tea during a fierce blizzard(暴风雪) in late November. The largebase he leads resembles a snowed-in college campus on holiday break，with the capacity to sleep morethan 10 times the 13 people who were staying on through the Antarctic winter. Yong Yu，a Chinesemicrobiologist，showed off the spacious building，with empty desks under an illustrated timelinedetailing the rapid growth of China's Antarctic operations since the 1980s.“We now feel equipped togrow,”he said.
L) As some countries expand operations in Antarctica，the United States maintains three year-round stations on the continent with more than 1,000 people during the southern hemisphere's summer, including those at the Amundsen-Scott station，built in 1956 at an elevation of 9,301 feet on a plateauat the South Pole. But US researchers quietly complain about budget restraints and having far fewerice breakers than Russia，limiting the reach of the United States in Antarctica.
M) Scholars warn that Antarctica's political drift could blur the distinction between military and civilian activities long before the continent's treaties come up for renegotiation，especially in parts of Antarctica that are ideal for intercepting(拦截) signals from satellites or retasking satellite systems，potentially enhancing global electronic intelligence operations.
N) Some countries have had a hard time here. Brazil opened a research station in 1984，but it was largely destroyed by a fire that killed two members of the navy in 2012，the same year that a diesel-laden Brazilian barge sank near the base. As if that were not enough，a Brazilian C-130 Hercules military transport plane has remained stranded near the runway of Chile's air base here since it crash-landed in 2014.
O)However，Brazil's stretch of misfortune has created opportunities for China，with a Chinese company winning the $100 million contract in 2015 to rebuild the Brazilian station.
P) Amid all the changes，Antarctica maintains its allure. South Korea opened its second Antarctic
research base in 2014，describing it as a way to test robots developed by Korean researchers for use in extreme conditions. With Russia's help，Belarus is preparing to build its first Antarctic base. Colombia said this year that it planned to join other South American nations with bases in Antarctica.
Q) “The old days of the Antarctic being dominated by the interests and wishes of white men from
European，Australasian and North American states are over,”said Klaus Dodds，a politics scholar at the University of London who specialises in Antarctica.“The reality is that Antarctica is geopolitically contested.”
36. According to Chinese officials，their activities in Antarctica lay greater emphasis on scientific research.
37.Efforts to create one of the world's largest ocean sanctuaries failed because of Russia's obstruction.
38. With several monitoring stations operating in Antarctica，Russia is trying hard to counter America's dominance in the field of worldwide navigational facilities.
39.According to geologists’estimates，Antarctica has enormous reserves of oil and natural gas.
40. It is estimated that Antarctica boasts of the richest reserves of fresh water on earth.
41. The demand for energy resources may compel renegotiation of Antarctica's treaties before their expiration.
42. Many countries are racing against each other to increase their business and strategic influence on Antarctica.
43. Antarctica's harsh natural conditions constitute huge obstacles to the exploitation of its resources.
44. With competition from many countries，Antarctica is no longer dominated by the traditional white nations.
45. American scientists complain about lack of sufficient money and equipment for their expansion in Antarctica.
The pattern of crime has varied very little over a long period of years.Murder reaches its high during July and August, as do rape and other violent attacks.Murder, moreover, is more than seasonal: it is a weekend crime.It is also a nighttime crime: 62 percent of murders are committed between 6 p.m.and 6 a.m.
Unlike the summer high in crimes of bodily harm, burglary(夜盗) has a different cycle.You are most likely to be robbed between 6 p.m.and 2 a.m.on a Saturday night in December, January, or February.The most uncriminal month of all？ May —except for one strange statistic.More dog bites are reported in this month than in any other month of the year.
Apparently our intellectual seasonal cycles are completely different from our criminal tendencies.Professor Huntington, of the Foundation for the Study of Cycles, made extensive studies to discover the seasons when people read serious book, attend scientific meetings, make the highest scores on examinations, and propose the most changes to patents (专利).In all instances, he found a spring peak and an autumn peak separated by a summer low.On the other hand, Professor Huntington’s studies indicated that June is the peak month for suicides and admissions to mental hospitals.June is also a peak month for marriages!

B.May
C.June
D.October
9.In Paragraph 4, why is an exclamation mark (感叹号“!”) used at the end of the last sentence？()
A.Because the author is surprised that so many people marry in June.
