4.Whether in the home or the workplace,social robots are going to become a lot more common in the next few years.Social robots are about to bring technology to the everyday world in a more humanized way,said Cynthia Breazeal,chief scientist at the robot company Jibo.
While household robots today do the normal housework,social robots will be much more like companions than mere tools.For example,these robots will be able to distinguish when someone is happy or sad.This allows them to respond more appropriately to the user.
The Jibo robot,arranged to ship later this year,is designed to be a personalized assistant.You can talk to the robot,ask it questions,and make requests for it to perform different tasks.The robot doesn't just deliver general answers to questions; it responds based on what it learns about each individual in the household.It can do things such as reminding an elderly family member to take medicine or taking family photos.
Social robots are not just finding their way into the home.They have potential applications in everything from education to health care and are already finding their way into some of these spaces.
Fellow Robots is one company bringing social robots to the market.The company's"Oshbot"robot is built to assist customers in a store,which can help the customers find items and help guide them to the product's location in the store.It can also speak different languages and make recommendations for different items based on what the customer is shopping for.
The more interaction the robot has with humans,the more it learns.But Oshbot,like other social robots,is not intended to replace workers,but to work alongside other employees."We have technologies to train social robots to do things not for us,but with us,"said Breazeal.

33.How are social robots different from household robots?B
A.They can control their emotions.
B.They are more like humans.
C.They do the normal housework.
D.They respond to users more slowly.
34.We can learn from the last paragraph that social robots willB.
A.train employees
B.be our workmates
C.improve technologies
D.take the place of workers
35.What does the passage mainly present?D
A.A new design idea of household robots.
B.Marketing strategies for social robots.
C.Information on household robots.
D.An introduction to social robots.

分析 本文属于科教类的短文阅读.文章主要介绍了社会机器人的功能与作用,对家用机器人和社会机器人两者进行了分析对比.

解答 BBD
33.B细节理解题.根据文章第二段While household robots today do the normal housework,social robots will be much more like companions than mere tools.可知社会机器人更像人或不是纯粹的工具.故选B.
34.B 推理判断题.根据最后一段Breazeal 的话"We have technologies to train social robots to do things not for us,but with us"可以推断出社会机器人可以和我们一起做事情.故选B.
35.D 主旨大意题.根据全文内容可知,文章主要介绍了社会机器人的功能与作用.故选D.

点评 解答细节理解题时,一个常用的方法就是运用定位法,即根据题干和选项中的关键词从原文中找到相关的句子,与选项进行比较从而确定答案;推理判断题既要求学生透过文章表面文字信息推测文章隐含意思,又要求学生对作者的态度、意图及文章细节的发展作正确的推理判断,力求从作者的角度去考虑,不要固守自己的看法或观点.

14.In Silicon Valley,it's never too early to become an entrepreneur.Just ask 13-year-old David Moore.The eighth-grader has launched a company last October to develop low-cost machines to print Braille(布莱叶盲文).David built a Braille printer with a Lego Mindstorms EV3 kit as a school science fair project last year after he asked his parents a simple question:How do blind people read?"Google it,"they told him.David then did some online research and was shocked to learn that Braille printers cost at least 2,000-too expensive for most blind readers."I just thought that price should not be there.I know that there is a simpler way to do this,"said David,who demonstrated how his printer works at the kitchen table where he spent many late nights building it.David wants to improve the"Braigo"-a name that combines Braille and Lego-and develop a  Braille printer that costs around 350 and weighs just a few pounds,compared with current models that can weigh more than 20 pounds."My end goal would probably be having most of the blind people…using my Braille printer,"said David,who lives in the Silicon Valley suburb of Santa Clara,just minutes away from Intel headquarters.
     After the Braigo won numerous awards and enthusiastic support from the blind community,David started Braigo Labs last summer with an initial 35,000 investment from his dad."We as parents started to get involved more,thinking that he's on to something and this new way process has to continue,"said his father,Matthew Moore,an engineer who works for Intel.
Intel officials were so impressed with David's printer that in November they invested an undisclosed sum in his start-up.They believe he's the youngest entrepreneur to receive venture capital money invested in exchange for a financial stake in the company."He's solving a real problem,and he wants to go off and challenge an existing industry,"said Edward Ross,director of Inventor Platforms at Intel.Now the company is using the money to hire professional engineers and advisers to help design and build Braille printers based on David's ideas.It aims to have a prototype (样机) ready for blind organizations to test this summer and have a Braigo printer on the market later this year.

66.Which of the followings is NOT the description of Braigo?C
A.The name"Braigo"comes from Braille and Lego.
B.The blind are in favor of the new type of printer.
C.It costs less money and weighs just a few pounds.
D.David planned to improve Braigo and make it lighter but easier to use.

15.A wood fire can be handy when you're camping.You can roast marshmallows or stay warm,for example.Forest fires that rage out of control,however,are a big problem.
Wildfires cause hundreds of millions of dollars in damage every year.And the amount of destruction has grown over the last 2 decades,especially in the western United States.
To understand better why the northern Rocky Mountains region has been hit especially hard by wildfires,scientists from the University of Arizona in Tucson looked at weather,snow,and fire records from 1970 to 2003.^
Their study showed that,between 1987 and 2003,fires burned an area 6.5 times larger than the area burned between 1970 and 1986.The fire season also started earlier-,and its average length increased by 78 days.
Warmer spring and summer temperatures appear to be part of the explanation for this change.The average temperature in the study's more recent period was 0.871 higher than it was in the earlier period.And this trend is likely to continue.Experts predict that average summer temperatures may rise between 2¾and 5¾by the year 2050 in western North America.‘
Hie timing of snowmelt appears to be another cause of the fire boom.When snow melts early in the season,forests become drier through the summer and catch fire and burn more easily.Western snow packs now typically melt a week to a month earlier than they did 50 years ago,according to recent studies.
Some people have blamed the growing fire risk on policies that allow bush and branches to build up on forest floors.But clearing bush by itself won't help much if changes in climate are largely responsible for increasingly severe forest fires.
43.The main purpose of studying the records from 1970 to 2003 was toD.
A.find out solutions to forest fires
B.prevent wildfires from happening frequently-
C.know more about the climate changes in the past decades
D.find out the causes of wildfires in the northern Rocky Mountains region
44.Scientists fix>m the University of Arizona found out the following EXCEPTD
A.western snow packs melt earlier than they did 50 years ago
B.fires burned larger area between 1987.and 2003 than between 1970 and 1986
C.the fire season between 1987 and 2003 was longer than that between 1970 and 1986
D.the average summer temperature will be I9C and 5¾higher by 2050 than it is now
45.Which of the following statements will Scientists from the University of Arizona agree to?C
A.More wildfires lead to the trend of global warming.
B.Hot summers have nothing to do with the increasing wildfires.
C.The earlier snow melts,the more probably forest fires will happen.
46.Clearing bush will help control the increasingly severe forest fires.What is the main idea the author aims to express in the passage?C
A.The damages caused by wildfires.
B.The results of a study on wild fires.
C.The causes of fires in the United States.
D.The changes in climate in the western United States.
12.To help make up for sleep lost during marathon night flights,migrating(迁徙) birds take hundreds of power nap(小睡) during the day,each lasting a few seconds.
Every autumn,Swainson's thrushes(画眉) fly up to 3,000miles from their breeding grounds in northern Canada and Alaska to winter in Central and South America.Come spring,the birds make the long trip back.
The birds fly mostly at night and often for long hours at a time,leaving little time for sleep.So to get through these tiresome periods,thrushes,during autumn and spring when the birds are normally migrating,change their sleep patterns,staying awake at night and resting during day.But instead of sleeping for a long period at a time,the birds took several naps a day,each one lasting only 9seconds on average.
The thrushes also mixed up their shut-eye sessions with two other forms of sleep.In one,called unilateral eye closure,or UEC,the birds rested one eye and one half of their brains while their other eye and half brain remained open and active,protecting them from danger.
The birds also occasionally slipped into another state,one that any college student who has ever been stuck in a boring lecture can relate to.Called drownsiness(睡意),this state is characterized by a partial shutting of both eyes that still allows for some visual processing.
"In terms of quality,drowsiness may be less useful than normal sleep,but it may also be safer."said Fuchs.
What's interesting is that even animals should make up for sleep loss.That a need for sleep cannot be lost even in these birds means the importance of sleep for many,if not all,animals,not to mention human.

29.What would be the best title for the text?D
A.Migrating Birds Travel for Long Hours
B.Migrating Need Help
C.How Birds Migrate during Autumn
D.Migrating Birds Take Many Daily Power Naps
30.According to the text,when having drowsiness,the thrushesC.
A.will rest one eye and the other active
B.will often sleep during day
C.will still be careful with the possible dangers
D.will not see anything in front of them
31.What can we learn from the text?A
A.Sleep is important for human being.
B.Animals need sleep to rest.
C.Migrating birds need sleep only during day.
D.College students often have drowsiness in fall.
19.Some people are like homing pigeons:Drop them off anywhere,and they'll find their way around.Other people,though,can't tell when they're holding a map upside down.Are the directionally challenged just bad learners?
Not all of your navigational (导航的)skills are learned.Research shows that your sense of direction is innate.An innate ability is something you are born with.Your brain has special navigational neurons-head-direction cells,place cells,and grid cells (网格细胞)-and they help program your inside compass when you're just a baby.
In 2010,scientists carried out an experiment to study baby rats'neural activity in their brains.Although the rats were newborns,the researchers discovered that their head-direction cells (which help them recognize the direction they're facing) were fully grown and developed.The rats,it seemed,were born with a sense of direction.And they hadn't even opened their eyes yet!
Humans,of course,are not rats.But the hippocampus-the brain area we use for navigation-is similar in most mammals.If the rat's compass develops this way,then it's likely that a human's compass does,too.
If we're born with a sense of direction,then why are some people so good at getting lost?The scientists found that the two other cells-place and grid cells-developed within the first month.Place cells are thought to help us form a map in our mind,while grid cells help us navigate new and unfamiliar places.The two cells work together,and that's where the trouble might be.
People who took part in a 2013study played a video game that required them to travel quickly between different places.Monitoring their brains,the scientists found that grid cells helped the gamers recognize where they were-even without landmarks.According to researcher Michael Kahana,differences in how grid cells work may help explain why some people have a better sense of direction than others.

32.What did the 2010research find?A
A.Rats have a natural ability to recognize directions.
B.Rats'hippocampus is different from that of humans.
C.Rats usually find their way without opening their eyes.
D.Baby rats have as many head-direction cells as grown-ups.
33.What do we know about our navigational neurons?D
A.Place cells let us know how to read a map.
B.Grid cells help us reach the place we are going to.
C.They help us use a compass when we lose our way.
D.Place and grid cells grow later than head-direction cells.
34.Why are some people so good at getting lost?B
A.They can't remember landmarks.
B.Their grid cells can't work very well.
C.They are unfamiliar with new places.
D.Their ability to follow directions is poor.
35.What is the text mainly about?A
A.Human navigational skills.
B.The compass in rats'body.
C.Why grid cells are useful.
D.How homing pigeons work.
9.Cardiovascular disease(心血管疾病) is the main cause of early death in China and many developing countries.Studies show that it kills more than 17million people around the world every year.In the next 15years that number is expected to rise to 23million.These deaths are,for the most part,preventable.
At a recent agreement signing ceremony in Washington D.C.,Douglas Boyle made a speech.He said the partnership can help people live longer and healthier lives.
The agreement between the American Heart Association and China has three main parts.It calls for increasing opportunities for researchers,health care providers and public health specialists in the U.S.to meet with those in China.The agreement also seeks the sharing of cardiovascular research.And,finally,it calls for training in China of life-saving techniques such as CPR.
CPR can restart a stopped heart.It has helped lower death rates from heart disease in the United States by 30percent.Improvements in medical science and educational campaigns about preventing heart disease also played a part.
The question is,will a by-stander in China give CPR to a complete stranger having a heart attack?
Several media reports have suggested people in China may be resistant to helping strangers in medical emergencies.This could be because the person helping can be held legally responsible for damage to the injured person.
Some relevant reports once went viral on the web.In a very short time millions of people read and made comments on them.These incidents may be few,but they draw attention to a lacking area of China's legal system.China does not have a national Good Samaritan law.Good Samaritan laws protect people who aid others in medical need.

29.What do you know about cardiovascular disease from the text?B
A.It is incurable.
B.It is deadly.
C.It is caused by overweight.
D.It is universal in the U.S.
30.We can infer that American public health specialists willA.
A.have more chances to communicate with those in China
B.do more experiments in the lab
C.give training to the doctors around the world
D.share their personal experiences with the world
31.People in China might hesitate to carry out CPR to a stranger probably becauseC.
A.they haven't grasp this technique
B.CPR is difficult to carry out
C.they are afraid to get into trouble
D.CPR is not fit for the Chinese
32.Which of the following can probably replace the underlined words"went viral"in the last paragraph?D
A.Disappeared finally.
B.Found immediately.
C.Ignored completely.
D.Spread quickly.
16.The capital of Switzerland,Bern,is a beautiful city.It was founded in 1191  and has a lot of attractions and historic sites as well as an active cultural life.It is here that Albert Einstein once worked.
    The city of Bern was built with local sandstone in Gothic style(哥特式)with more arcades(拱廊)than any other city in Europe.It is one of the most attractive old towns in Europe,and is famous for its great sandstone buildings,historical towers and eleven famous fountains.Over the centuries,the city has been protected very well,and in 1 983 the UNESC0(联合国科教文组织)claimed Bern a World Heritage Site.
    One house after the other and shop after shop,rows of shops are connected by long sandstone arcades.Rain or shine,it is a pleasure to walk along one of the longest shopping streets.Bern has Switzerland's tallest Gothic cathedral(大教堂).The Münster-Terrasse,a square in front of the cathedral,has been a f amous meeting place for centuries.
    The wonderful Clock Tower has puppets(木偶)that come out before the hour and perform a 1ittle short play.The Center Paul Klee shows the largest collection in the world of one of the world's greatest 20th century artists.The Swiss Alpine Museum displays a history of the Swiss Alps(阿尔卑斯山).Bern's shining green river,Aare,winds its way alongside the old town and is lined with a number of scenic spots.Only a few minutes'walk from the station will take you to its tree-lined banks surrounded by nature.The Aare attracts people of all ages,especially in summer when the clean water invites you to jump into the river.It is during this time that many of the people in Bern enjoy swimming.
39.According to the passage,which of the following does Bern NOT have?B

13.A glass a day keeps obesity at bay.Alcohol has always been thought to cause weight gain because of its high sugar content,but new research suggests a glass a day could form part of a diet.Looking at past studies they found that,while heavy drinkers do put o weight,those who drink in moderation can actually lose weight.
A spokesman for the research team at Navarro University in Spain says,"Light to moderate alcohol intake,especially of wine,may be more likely to protect against,rather than promote,weight gain."The Inter national Scientific Forum on Alcohol reviewed the findings and agreed with most of the conclusions,particularly that current data do not clearly indicate if moderate drinking increases weight.
Boston University's Dr.Harvey Finkel found that the biologic mechanisms (生物学机制) relating alcohol to changes in body weight are not properly understood.His team pointed out the strong protective effects of moderate drinking on the risk of getting conditions like diabetes (糖尿病),which related to increasing obesity.Some studies suggest that even very obese people may be at lower risk of diabetes if they are moderate drinkers.
The group says alcohol provides calories that are quickly absorbed into the body and are not stores in fat,and that this process could explain the differences in its effects from those of other foods.They agree that future research should be directed towards assessing the roles of different types of alcoholic drinks,taking,into consideration drinking patterns and including the past tendency of participants to gain weight.
For now there is little evidence that consuming smfill to moderate amounts of alcohol on a regular basis increases one's risk of becoming obese.What's more,a study three years ago suggested that resveratrol,a compound present in grapes and red wine,destroy fat cells.
24.Who is the passage intended for?B
A.Those who produce wine.
B.Those who have drinking habit.
C.Those who sell alcohol      
D.Those who wish to quit drinking.
25.What does the phrase"in moderation"in the first paragraph refer to?C
A.Excitedly.B.Carefully.C.Properly.D.Frequently.
26.What can we learn from the passage?D
A.Current data clearly show that moderate drinking increase weight.
B.Resveratrol is proved to increase the risk of becoming fat.
C.The specific roles of different types of alcoholic drinks are very clear.
D.The research found moderate drinking has a strong protective effect.
27.What is most likely to be discussed in the paragraph that follows?D
A.How to do some easy experiments.
B.How to reduce the calories contained in wine.
C.How to make wine in a healthy way.
D.How to prove the finding mentioned above.
12."Extra?Extra!Gasoline hits four dollars a gallon!"
No one will really be shocked一except,perhaps,the old-timers who tell about the good old days when gas was three gallons for a dollar,and people drove around"just for the fun of it". As a matter of fact; the price of gas has been rising fast and steadily for several years,and many adjustments have already been made.
There was,for a time,considerable unemployment in the auto industry,and three quarters
of the garages and service stations have gone out of business.However; the bicycle and
motor-scooter business has flourished(兴旺); and many people have found employment there:Now that Federal Motors has brought out its new Lilliput,which travels forty miles on a gallon,the auto business is picking up again.The factories that haven't switched over to two-wheel transportation are working on their new smaller models.There is talk,too,about bringing out new steam and electric automobiles that will be just as economical as the old cars.
In the meantime,streetcars are gradually replacing buses all over the country because of the greater economy of electric power.And many people who have seldom used public transportation are now riding the streetcars while their automobiles rust(生锈)in their garages. There's no market at all for their big,luxurious cars,for only the wealthy can now afford to operate them.Many people are now shopping in their own neighborhood,and small businesses are thriving.
Ministers,educators,and editorial writers are pointing out that there has been a great
improvement in family life.Families now stay at home more for their fun,and children and
parents are becoming better acquainted.The stores report a booming business in parlor games,hobby materials,books,musical instruments and albums.
People have lost their pale indoor look.The revival of the lost art of walking has brought a healthy pink back to many a cheek.This return to the heels has revolutionized the clothing styles; people now need to be ready for all kinds of weather:
These conditions,however,may not last.Already our clever chemists are at work on new
synthetic fuels which,they say,will put us right back where we were一on wheels.Shall w e
wish them success or not?

D.The auto industry has been forced to develop new models which are more economical.
