1、 Passage Two
Questionsare based on the following passage.
The Wall Street Journal quoted sources close to thecompany as saying a run of 4.000 devices will be manufacturednext month.The tablet will have two rear-facing camerasand advanced imaging software——and will be shown off at the firm’s forthcomingdevelopers’ conference.Google has said it will not commenton “rumor and speculation”.But in March,Google showed off Project Tango,all effortto bring 3D technology to its handheld devices.Aprototype smart phone had been given out to 200 developers to try out.
The technology makes use of infrared sensors tomeasure depth of surroundings.While the ability to create 3Dimages with small devices is by no means a new technological feat,Google’s strategy will be to harness the hardware to contribute to,among other things,its mapping effort.For instance,the devices could be used tocreate quickly a 3D map of indoor environments.Accordingto the Wall Street Journal,the 3D tablet will be shownof fat Google’s annual developers’ conference at the end of June.
As it did with the Google Glass eyewear product.itis expected the firm will A.low a select number ofdevelopers and engineers to experiment with the technology before a consumerlaunch is planned.although still a relatively minorindustry,the race to create the “killer app” forbuilding and viewing virtual reality environments is building a pace.In March,Facebook swooped in on a$2bn(£1.2bn) deal for OculusVR,a company making a virtual reality headset.
A mini-site for Project Tango has highlighted a fewof the firm’s plans in the area.“Project Tango is an attempt tocreate a mobile device unlike like any other,”the siteexplains.“A mobile device that shares our sense ofspace and movement,that understands and perceives theworld the same way we do.”
In the past few years,devices able to view andcreate 3D images have made it to market,but suffered heavilyfrom a lack of consumer interest,said Jack Kent,an analyst at IHS.“If Google really pushesit,that might change也e dynamicsof the market。”he told the BBC.

2、根据以下资料,回答题:
        Drink from plastic bottles can raise the body's levels of a controversial "gender-bending" chemical by more than two thirds, according to tests.
        Experts have been concerned about the possible health effects of bisphenolA (BPA.--an everyday chemical used in many plastic food and drink containers and tins as well as clear baby bottles--which is officially classified as toxic in some countries.A study found that participants who drank for a week from polycarbonate (聚碳酸酯) bottles showed a 69 percent increase in their urine (尿液) of BPA.
        Researchers did not say how much liquid was drunk per day.Researchers from Harvard School ofPublic Health studied 77 students, who had first undergone a seven-day "washout" phase in which theydrank all cold beverages (饮料) from stainless steel bottles in order to minimise BPA exposure.
        They were then given two polycarbonate bottles and asked to drink all cold beverages from themduring the next week.Previous studies have suggested that high levels of BPA consumption are linked tobirth defects, growth problems and an increased risk of heart disease.In particular there are fears thatheating the bottles, as parents would do when warming their baby's milk, causes the chemical to leak inpotentially dangerous quantities into the liquid contained within.
        "If you heat those bottles, as is the case with baby bottles, we would expect the levels to beconsiderably higher.This would be of concern since infants may be particularly susceptible to BPA'shormone gland-disrupting (扰乱腺体极速分泌) potential." said the senior author of the latest study, Karin B.Michels.
        Most adults carry BPA in their bodies but expert opinion on the risks is divided.The European Food Safety Authority believes that people naturally convert the chemical into less harmful substances in the body.
        Previous studies had found that BPA could leach (渗出 ) from polycarbonate bottles into theircontents, but this study is the first to show the size of the corresponding increase in urinary BPAconcentrations in humans.
        Harvard researcher Jenny Carwile said, "While previous studies have demonstrated that BPA is linkedto adverse health effects, this study fills in a missing piece of the puzzle--whether or not polycarbonateplastic bottles are an important contributor to the amount of BPA in the body."

What do we know about bisphenol A (BPA.from the beginning of the passage?
A.It is certain substance taken in by human beings every day.
B.It is a component contained in a number of plastic products.
C.It is an element that plays a decisive role in people's gender.
D.It is a kind of chemical that is universally regarded poisonous.


3、根据下列材料,请回答题:
Questions 36 to 45 are based Oil the following passage.
The concept of man versus machine is at least as old as the industrial revolution, but this phenomenon tends to be most acutely felt during economic downturns and slow recoveries. Since technology has such a big 36 for eating up human jobs, this phenomenon will continue to restructure our economy in ways we can't immediately foresee.
When there is exponential (指数的. 37 in the price and performance of technology, jobs that were once thought to be 38 from automation suddenly become threatened. This is a powerful argument, and a scary one. And yet, John Hagel, author of The Power of Pull and other books, says the argument misses the reason why these jobs are so vulnerable to technology in the first palce.
Hagel says we have designed jobs in the U.S. that tend to be tightly scripted and highly 39 ones that leave no room for individual initiative or creativity. In short, these are the types of jobs that machines can 40 much better than human beings. That is how we have put a giant 41 sign on the backs of
American workers.
It's time to 42 the formula for how work is conducted, since we are still relying on a very 20thcentury 43 of work, Hagel says. In our 44 changing economy, we more than ever need people in the workplace who can take initiative and exercise their imagination to respond to 45 events. That's not something machines are good at. They are designed to perform very predictable activities.

A.appetite
B.calculate
C.competition
D.distinct
E.exceedingly
F.immune
G.improvement
H.norm
I.notion
J.perform
K.rapidly
L.reinvent
M.standardized
N.target
O.unexpected
请回答(36)题__________.


4、Questionsare based on the following passage.
In recent years, a growing body of research has shown that our appetite and food intake are influenced by a large number of factors besides our biological need for energy, including our eating environment and our perception of the food in front of us.
Studies have shown, for instance, that eating in front of the TV (or a similar distraction) can increase both hunger and the amount of food consumed. Even simple visual cues, like plate size and fighting, have been shown to affect portion size and consumption.
A new study suggested that our short-term memory also may play a role in appetite. Several hours after a meal, people's hunger levels were predicted not by how much they'd eaten but rather by how much food they'd seen in front of them in other words, how much they remembered eating..
This disparity (差异) suggests the memory of our previous meal may have a bigger influence on our appetite than the actual size of the meal. says Jeffrey M. Brunstrom, a professor of experimental psychology at the Univerity of Bristol.
"Hunger isn't controlled solely by the physical characteristics of a recent meal. We have identified an
independent role for memory for that meal,'" Brunstrom says. "This shows that the relation_ship between hunger and food intake is more complex than we thought. ""
These findings echo earlier research that suggests our perception of food can sometimes trick our body's response to the food itself. In a 2011 study, for instance, people who drank the same 380-calorie(卡路里) milkshake on two separate occasions produced different levels of hunger-related hormones (荷尔蒙), depending on whether the shake's label said it contained 620 or 140 calories. Moreover, the participants reported feeling more full when they thought they'd consumed a higher-calorie shake.
What does this mean for our eating habits? Although it hardly seems practical to trick ourselves into eating less. the new fmdings do highlight the benefits of focusing on our food and avoiding TV and multitasking while eating.
The so-called mindful-eating strategies can fight distractious and help us control our appetite,
Brunstrom says.
What is said to be a factor affecting our appetite and food intake?
A.How we perceive the food we eat. 
B.what ingredients the food contains. 
C.When we eat our meals. 
D.How fast we eat our meals.


5、回答题:
A Mess on theLadder of Success
        A) Throughout Americanhistory there has almost always been at least one central economic narrativethatgave the ambitious or unsatisfied reason to pack up and seek their fortuneelsewhere. For the first 300or so years of European settlement, the story wasabout moving outward: getting immigrants to thecontinent and then to thefrontier to clear the prairies ( 大草原), drain thewetlands and build new cities.
        BBy the end of the 19thcentury, as the frontier vanished, the US had a mild panic attack. What wouldthisenergetic, enterprising country be without new lands to conquer? Some people,such as Teddy Roosevelt, decided to keep on conquering ( Cuba, the Philippines,etc.), but eventually, in industrialization, the US found a new narrative ofeconomic mobility at home. From the 1890s to the
        1960s,people moved from farm to city, first in the North and then in the South. Infact, by the 1950s,there was enough prosperity and white-collar work that manybegan to move to the suburbs. As the population aged, there was also a shift from the cold Rust Belt to the comforts of the Sun Belt, Wethink of this as anold person's migration, but it created many jobs for the young in coustructionand health care, not to mention tourism, retail and restaurants.
        CFor the last 20 years-from the end of the coldwar through two burst bubbles in a single decade--theUS has been casting aboutfor its next economic narrative. And now it is experienc.ing another periodofpanic, which is bad news for much of the workforce but particularly for itsyoungest members.
        DThe US has always been a remarkably mobilecountry, but new data from the Census Bureau indicatethat mobility has reachedits lowest level in recorded history. Sure, some people are stuck in homesvaluedat less than their mortgages (抵押贷款), but many youngpeople,-who don't own homes anddon't yet have famih'es--are staying put, too.This suggests, among other things, that people aren'tpacking up for neweconomic opportmtities the way they used to. Rather than dividing the countryintothe 1 percenters versus ( 与……相对) everyone else, the split in our economy is really between twootherclasses: the mobile and immobile.
        E) Part of the problem is that the country'slargest industries are in decline. In the past, it was perfectlyclear whereyoung people should go for work (Chicago in the 1870s, Detroit in the 1910s,Houston inthe 1970s) and, more or less, what they'd be doing when they gotthere ( killing cattle, building cars,~selling oil). And these industries werelarge enough to offer jobs to each class of worker, fromunskilled laborer tomanager or engineer. Today, the few bright spots in our economy are relativelysmall (though some promise future growth) and decentralized. There are greatjobs in Silicon Valley, in the biotech research capitals of Boston andRaleigh-Durham and in advanced manufacturing plantsalong the southern 1-85corridor. These companies recruit all over the country and the globe forworkerswith specific abilities.(You don't need to be the next Mark Zuckerberg, founderofFacebook, to get a job in one of the microhubs (微中心), by the way. But youwill almost certainlyneed at least a B, A. in computer science or a year or twoat a technical school.) This newer, select job market is national, and itoffers members of the mobile class competitive salaries and higherbargainingpower.
        F) Many members of the immobile class, on theother hand, live in the America of the gloomy headlines.If you have nospecialized skills, there's little reason to uproot to another state and be thelast in linefor a low-paying job at a new auto plant or a green-energy startup.The surprise in the census (普查)data, however, is that the immobile workforce is not limited tounskilled workers. In fact, many have a college degree.
        G) Until now, a B.A. in any subject was a near-guarantee of at least middle-class wages.But today, aquarter of college graduates make less than the typical workerwithout a bachelor's degree. David Autor, a prominent labor economist at M. I.T., recently told me that a college degree alone is nolonger a guarantor of agood job. While graduates from top universities are still likely to get a goodjobno matter what their major is, he said, graduates from less-famous schoolsare going to be judged onwhat they know. To compete for jobs on a nationallevel, they should be armed with the skills thatemerging industries need,whether technical or not.
        H) Thosewithout such specialized skills--like poetry, or even history, majors--arealready competing with their neighbors for the same sorts of second-rate,poorer-paying local jobs like low-levelmanagement or big-box retail sales. Andwith the low-skilled labor market atomized into thousands ofmicroeconomies,immobile workers are less able to demand better wages or conditious or toacquire valuable skills.
        I) Sowhat, exactly, should the ambitious young worker of today be learning?Unfortunately, it's hard tosay, since the US doesn't have one clear nationalproject. There are plenty of emerging, smaller industries, but which ones arethe most promising? (Nanotechnology's (纳米技术) moment of remarkable growth seems to havebeen 5 years into the future for something like 20 years now.) It'snot clearexactly what skills are most needed or if they will even be valuable in adecade.
        J) Whatis clear is that all sorts of government issueseducation, health-insuranceportability, worker retraining--are no longer just bonuses to alreadyprosperous lives but existential requirements. It's inall of our interests tomake sure that as many people as possible are able to move toward opportunity,and, America's ability to invest people and money in exciting new ideas isstill greater than that of most other wealthy countries. (As recently as fiveyears ago, US migration was twice the rate of EuropeanUnion states.) That, atleast, is some comfort at a time when our national economy seems to besearchingfor its next story line.
Unlike in the past, a college degree alone does not guarantee a good job for its holder.
