题目内容

A.doingB.to doC.having doneD.done

分析 在恰当进行的情况下,网上购物能给我们省下很多时间和钱.

解答 答案是D.本题考查"连词+分词"的结构."连词+分词"的结构在句中往往做状语,属于分词做状语;分词做状语时分词的选择是看分词和句子主语之间的关系:分词和句子主语之间是主谓关系(主动关系),用现在分词;分词和句子主语之间是动宾关系(被动关系),用过去分词;本题中连词when后的do和句子主语E-shopping之间是被动关系,所以答案选择D.注意:1)"连词+分词"的结构中分词前不能有任何形式的be动词;2)注意区别,"疑问词+to do"在句中起着名词作用,做主语、宾语或表语,而"连词+分词"在句中充当状语.

点评 首先判断选项中的动词在句中是以谓语还是非谓语形式出现,然后根据选项在句中的功能结合非谓语的基本用法做出合理的判断.要关注常见非谓语动词的搭配.

19.The new high-speed railway line between Urumqi,capital of the Xinjiang Uygur self-governing region,and Lanzhou,capital of Gansu province,has cut train travel time by half to less than 12hours.
The dramatic improvement will benefit many families planning reunions for Spring Festival.
"For the first time,I feel home is not that far away after all."said Liang Shaofu as he boarded a high-speed train in Urumqi with six members of his family.
The 35-year-old left Lanzhou to set up a dry fruit business in Xinjiang eight years ago,and he has now settled in Urumqi.
The 1,776-km line,which passes through Qinghai province and is the country's first high-speed railway to be built in a high-altitude region,came into service on Dec 26.
"We normally drive home for Spring Festival to avoid the difficulties of buying seven train tickets for the whole family during the peak season."Liang said."Driving can be very tiring and dangerous sometimes,so one year we even decided not to go back to Lanzhou simply to avoid the trip."
More than 600,000passengers traveled on the line during its first month,and the Urumqi Railway Bureau said the introduction of high-speed services will ease transport pressure during the Spring Festival peak season.
The existing usual railway line could no longer support Xinjiang's development.All passengers trains will gradually shift to the new link,leaving the old one to be used for goods.As a result,Xinjiang's annual goods ability could reach 200million metric tons from the current 70million.
The line passes through areas that experience high winds,and it also crosses parts of the deserted Qinghai-Tibet Plateau and the bone-dry sands of the Gobi Desert.
The project could help China to promote its high-speed railway technology abroad,said Ma Xizhang,director of the Lanzhou-Xinjiang railway project's management department in Xinjiang.

16.How would you like an easy way to earn $2,500?All you have to do is to sit around and wait for your meals.There's a catch,however.You have to stay in a chicken cage with a stranger for a whole week.There are no books or television or radio for amusement.You can't leave until the week is up.And a camera will be recording your every move.
Two people actually took the job.The idea came from Rob Thompson,a video artist.He wanted to make a film about the way animals are treated.His goal was to raise people's awareness of the living conditions of animals that are raised for food.He decided to pay $5,000 out of his own savings to two people who were willing to live like chickens for a week.
    To Rob's surprise,quite a few people answered his advertisement.He had interviewed and selected Eric,a 24-year-old restaurant worker,and Para,a 24-year-old chemist.The plan was for them to spend seven days together in a chicken cage that was six feet long and three feet wide.A camera would record their experiences,which would take place in an art museum.
    The week was long and difficult.They slept on a hard wooden floor.They couldn't stand up without hanging their heads.They ate vegetables and drank water from a garden hosepipe.Their only privacy was a toilet surrounded by a curtain.There were no sinks,mirrors,or toothbrushes in the cage.Their only inspiration was the two framed checks that hung on the wall outside the cage.Visitors who came here were warned,"Do not feed the humans."
    Finally it was over,and Para and Eric appeared from their cage.They had survived the week,and they each had a $2,500 check in their hands.When Rob Thompson opened the cage,Eric came out,changed into clean clothes,and ate a chocolate bar right away."It's great to be able to stand up,"he said.Para just changed her clothes and left.After a week of visitors and reporters watching her,she didn't want to talk to anyone.

13.Imagine a town with crosswalks but no pedestrians,cars and trucks but no drivers.Welcome to Mcity,a fake(假的)"city"built by researchers who are testing out the driverless cars of the future.
The controlled test environment,which opened today (July 20,2015)at the University of Michigan in Ann Arbor,covers 32acres (the size of about 24football fields) and contains all the trappings of a real suburb or small city.There is an entire network of roads lined with sidewalks,streetlights,stop signs and traffic signals.There's even a"downtown"area complete with fake buildings and outdoor dining areas.
The idea behind Mcity is simple:test out new driverless car innovations(创新) in a human-free environment before these technologies are unleashed(投放) in the real world.
"Mcity is a safe,controlled,and realistic environment where we are going to figure out how the incredible(难以置信的) potential(可能性) of connected and automated vehicles can be realized quickly,efficiently(有效地) and safely,"Peter Sweatman,director of the Mobility Transformation Center at U-M,said in a statement.
The roads of Mcity are built to stand up to"strict,repeatable"testing,according to MTC officials.While Mcity drivers don't have to compete with real pedestrians,there will be one mechanical foot-traveler (a robot-like machine named Sebastian) that steps out into traffic to see whether the automated cars can hit the brakes in time.The fake city also features a traffic circle,a bridge,a tunnel,some unpaved(未铺砌的) roads,and even a four-lane(四车道的) highway with entrance and exit ramps(坡道),according to a report by Bloomberg Business.
In addition to evaluating fully automated,or driverless cars,the researchers also hope to test out so-called connected vehicles within Mcity's limits.Connected cars can either communicate with one another (vehicle-to-vehicle control,or V2V) or with pieces of equipment,such as traffic lights,that are located near roadways (vehicle-to-infrastructure基础设施 control,or V2I).
Even the smallest details of Mcity have been planned out in advance to copy the conditions that connected and automated vehicles could face in the real world.For example,there are street signs covered up with graffiti(涂鸦),and faded yellow and white lane markings line the streets.
Mcity is just one part of a much larger project that MTC and its partner organizations are establishing in an effort to get a whole fleet(车队) of connected and driverless cars on the road in Ann Arbor by 2021.In addition to the fake city,MTC is also continuing to launch connected and semi-autonomous(半自动) cars on real roadways.Eventually,the University of Michigan and the Michigan Department of Transportation said they hope to put 20,000connected cars on the roads of southern Michigan.
