5.It's a brand new world-a world built around brands.Hard charging,noise making,culture shaping brands are everywhere.They're on supermarket shelves,of course,but also in business plans for dotcom startups and in the names of sports complexes.Brands are infiltrating(渗透)people's everyday lives-by sticking their logos on clothes,in concert programs,on subway station walls,even in elementary school classrooms.
We live in an age in which CBS newscasters wear Nike jackets on the air,in which Burger King and McDonald's open newsstands in elementary-school lunchrooms,in which schools like Stanford University are endowed with a Yahoo!Founders Chair.But as brands reach (and then overreach)into every aspect of our lives,the companies behind them invite more questions,deeper examination-and an inevitable backlash (强烈反应) by consumers.
"Our intellectual lives and our public spaces are being taken over by marketing-and that has real implications for citizenship,"says author and activist Naomi Klein."It's important for any healthy culture to have public space-a place where people are treated as citizens instead of as consumers.We've completely lost that space."
Since the mid-1980s,as more and more companies have shiftedfrom being about products to being about ideas-Starbucks isn't selling coffee;it's selling community!-those companies have poured more and more resources into marketing campaigns.
To pay for those campaigns,those same companies figured out ways to cut costs else where-for example,by using contract labor at home and low-wage labor in developing countries.Contract laborers are hired on a temporary,per-assignment basis,and employers have no obligation to provide any benefits(such as health insurance)or long-term job security.This saves companies money but obviously puts workers in vulnerable situations.In the United States,contract labor has given rise to so-called McJobs,which employers and workers alike pretend are temporary-even though these jobs are usually held by adults who are trying to support families.
The massive expansionof marketing campaigns in the 1980s coincided with the reduction of government spending for schools and for museums.This made those institutions much too willing,even eager,to partner with private companies.But companies took advantage of the needs of those institutions,reaching too far,and overwhelming the civic space with their marketing agendas.

31.What does the passage intend to tell us?D
A.The problems with current corporate practices.
B.The nature of current marketing campaigns and strategies.
C.The importance of brands in American culture.
D.The excessive presence of brands and marketing in people's lives.
32.What is Naomi Klein's attitude towards the infiltration of brands into public spaces?A
A.Concerned.B.Indifferent.C.Favorable.D.Optimistic.
33.The passage suggests that most contract laborers in the U.S.B.
A.pretend to be permanent workers
B.may have trouble supporting their families financially
C.have work conditions comparable to those of low-wage workers overseas
D.are likely to receive health benefits from their employers
34.We may infer from the last paragraph thatC.
A.inadequate federal funding facilitated the privatization of schools and museums
B.government reduced spending for schools and museums for their cooperation with companies
C.public institutions were only too anxious to accept corporate marketing as a source of funding
D.by the 1980s,very few public institutions were not being funded by corporations.

2.A 16-year survey on the arctic Norwegian island of Svalbard found the reindeer(驯鹿)there have declined in weight by an alarming 12percent.The reduction in average body-mass is being blamed on global warming.
In research presented lately at a meeting of the British Ecological Society in Liverpool,scientists will explain how rising temperatures are making female reindeer difficult to obtain nutrients during important periods of being pregnant.
Snow in Svalbard typically covers the ground for eight months of the year,which,combined with low temperatures,limits grass growth to June and July.But as summer temperatures have increased by around 1.5℃,grasslands have become more productive,allowing female reindeer to gain more weight by the autumn and therefore to conceive(孕育)more calves.
However,warmer winters have brought with them greater rainfall which freezes when is settles on the snow,therefore locking out the reindeer from the life-supporting food below.As a result,female reindeer are becoming starved,causing them to give birth to much lighter young.The average mass of an adult reindeer in 1998,when the survey began,was 55kg,but by 2016 IT had dropped to 48kg.
Professor Steve Albon,an ecologist at the James Hatton Institute in Aberdeen,said that,because the mammals have a relatively high surface-area-to-volume ratio(表面积与体积比),they are no particularly energy efficient.
Reindeer can often access the inadequate food sources beneath the snow by clearing IT away with their antlers(鹿角),but they cannot break through the hard ice.Without access to the food in winter,calves are being born far lighter than they should be.Numbers of reindeer have also increased rapidly in the past 20 years,meaning that those which are born are facing greater competition for food."The implication(含义)are that there may well be more smaller reindeer in the Arctic in the coming decades,but possibly at the risk of catastrophic die-offs because of increased ice on the ground,"said Professor Albon Despite the gloomy findings,reindeer appear to be suffering less from the impact of climate change than some other arctic species.

32.Which of the following may be the most important reason for the smaller reindeer?D
A.Heavy snow.
B.Greater rainfall.
C.Hard ice.
D.Global warming.
33.According to the passage,rising temperatures will not lead toC.
A.grass growing more rapidly in summer
B.more rainfall in the arctic area in winter
C.female reindeer's gaining more weight in winter
D.female reindeer's suffering from hunger in winter
34.What does the underlined word"gloomy"in the last paragraph mean?C
A.Exciting.
B.Optimistic.
C.Disappointing.
D.Doubtful.
35.How does the writer develop the passage?A
A.By analyzing the research.
B.By classification of reindeer.
C.By comparing opinions of experts.
D.By telling stories of different species.
