It is an increasingly urgent question，given the recent mining accidents in Sago，W.Va and Huntington，Utah.A small group of engineers and robotics experts look forward to a day in the nottoodistant future when robots and other technology do most of the dangerous mining work.Robotic technology, in particular, holds much promise, McAteer says, especially when it comes to mapping mines and rescuing trapped minersthe special operations of the mining industry.One of the first mining robots was developed five years ago at Carnegie Mellon Universitys Robotics Institute.It was called Groundhog.It used lasers(激光器) to “see” in dark tunnels and map abandoned minessome of the most dangerous work in the business.The latest design is called Cave Crawler.Its a bit smaller than Groundhog，and even more advanced.It can take photos and videos and has more sensors that can detect the presence of dangerous gases.Incredibly，the robot has a real sense of logic.If it comes across an obstacle it gets momentarily confused.It has to think about what to do and where to go next.Sometimes it throws a fit just like a real person.The greatest problem，though，is cost.The money of the earliest research project was provided by the government, but that money had dried up，and its not clear where future money will come from.Partly for that reason，and partly because of advances in safety，mining is not nearly as dangerous as it was in the past.Since 1990，fatalities(致命性) have declined by 67% and injuries by 51%，according to the National Mining Association.Some experts predict that robots in mines will serve much of the same function that they do in the automotive industry.The robots do the most boring and dangerous jobs，but wont get rid of the need for human workers.16.The latest robot is more advanced than Groundhog, mainly because .A.it can map abandoned minesB.it has a real sense of logicC.it can see in the dark tunnelsD.its smaller than Groundhog17.The underlined phrase “throws a fit” in Paragraph 4 probably means “ ”.A.gets sick B.gets angryC.becomes hungry D.becomes cheerful18.We can infer from the last paragraph that .A.the mine robots will have a very bright futureB.robots in mines will serve much in the automotive industryC.there will be no need for human workers in minesD.robots in mines only do some simple jobs now.完形填空(2016河北邯郸魏县一中高二期中)I will never forget the year I was about twelve years old.My mother told us that we would not be 19 Christmas gifts because there was not enough money.I felt sad and thought，“What would I say when the other kids asked what Id 20 ？” Just when I started to 21 that there would not be a Christmas gift that year，three women 22 at our house with gifts for all of us.For me they brought a doll.I felt such a sense of 23 that I would no longer have to be embarrassed when I returned to school.I wasnt 24 .Somebody had thought 25 of me to bring me a gift.Years later，when I stood in the kitchen of my new house，thinking how I wanted to make my 26 Christmas there special and memorable，I 27 remembered the womens visit.I decided that I wanted to create that same feeling of 28 for as many children as I could possibly reach.So I 29 a plan and gathered forty people from my company to help.We gathered about 125 orphans(孤儿) at the Christmas party.For every child，we wrapped colorful packages filled with toys，clothes，and school supplies， 30 with a childs name.We wanted all of them to know they were 31 .Before I called out their names and handed them their gifts，I 32 them that they couldnt open their presents 33 every child had come forward.Finally the 34 they had been waiting for came as I called out，“One，two，three.Open your presents！” As the children opened their packages，their faces beamed and their bright smiles 35 up the room.The 36 in the room was obvious，and 37 wasnt just about toys.It was a feelingthe feeling I knew 38 that Christmas so long ago when the women came to visit.I wasnt forgotten.Somebody thought of me.I mattered.19.A.sending B.makingC.receiving D.exchanging20.A.got B.preparedC.found D.expected21.A.doubt B.hopeC.accept D.suggest22.A.broke in B.turned upC.settled down D.showed off23.A.achievement B.lossC.relief D.justice24.A.blamed B.forgottenC loved D.affected25.A.enough B.littleC.poorly D.highly26.A.present B.recentC.first D.previous27.A.hardly B.occasionallyC.regularly D.instantly28.A.importance B.independenceC.strength D.safety29.A.kept up with B.came up withC.caught up with D.put up with30.A.none B.fewC.each D.some31.A.fine B.normalC.helpful D.special32.A.convinced B.guaranteedC.reminded D.promised33.A.until B.afterC.when D.since34.A.chance B.giftC.reward D.moment35.A.took B.litC.burned D.cheered36.A.atmosphere B.sympathyC.joy D.calmness37.A.such B.itC.something D.everybody38.A.from B.tillC.for D.by.短文改错(2017西藏拉萨中学高二月考)Hunter likes to go traveling in summe
