unit 4 sharing grammar课时作业第一节 完型填空its no 1 that kids love dinosaurs. many of them have even gone through whats called a “dinosaur phase”a period of time 2 they cant stop talking about dinosaurs, cant 3 without hearing a dinosaur bedtime story, and use a backpack with a dinosaur pattern on it.adults may have long 4 out of their dinosaur phase, but somehow the appeal is still there.the 5 consists in the success of steven spielbergs 1993 film jurassic park, and every following installment of the series. and in jurassic world: fallen kingdom, which was 6 in chinese mainland cinemas on june 15, these ancient beasts are taking over the 7 world once again.national geographic has an explanation behind the animals8. dinosaurs are “9 science and imagination meet”, which is probably what makes them so appealing, to kids and adults alike.dinosaurs are often compared to dragons, but are seen as cooler because theyre 10. the huge skeletons in museums prove their existence millions of years ago on the same earth that we now live on. 11, new discoveries have been made in different parts of the world that open up a bigger 12 of these ancient species. and how they went extinct is also a popular subject of 13 studies.however, we still seem to know so little about dinosaurs, and have to rely on our 14 when it 15 to questions like “how did they live?”, “what did they sound like?” and “how fast could they run?”. its this sense of mystery that 16 dinosaurs attraction compared to other fierce animals like lions and tigersanimals that can be easily seen in todays zoos.but theres more to this dinosaur appeal.according to guardian reporter brian switek, humans are fascinated by dinosaurs not just because were interested in their history, but also because were trying to have a better understanding of human history.“dinosaurs 17 be hollywood monsters, objects of scientific fascination and everything 18, but at the root of it, our fascination with them 19 from wanting to know more about the prehistory we 20,” he wrote.“the dinosaur story is part of our own.”1.a.wonderb.secret c.doubtd.question 2.a.thatb.whichc.when d.while 3.a.eatb.workc.playd.sleep 4.a.leftb.grown c.jumpedd.run 5.a.truthb.answerc.proof d.matter 6.a.shotb.introducedc.preparedd.released 7.a.competitiveb.fantasticc.modern d.magic 8.a.popularity b.successc.eternityd.extinction 9.a.whatb.whenc.howd.where10.a.inventedb.imaginaryc.real d.authentic11.a.meanwhile b.thereforec.howeverd.hence12.a.imageb.windowc.sightd.picture13.a.literaryb.scientificc.humanitariand.societal14.a.imagination b.determinationc.perseveranced.ambition15.a.relatesb.correspondsc.comes d.refers16.a.leads tob.turns toc.points tod.adds to17.a.can b.mustc.shouldd.may18.a.in briefb.in casec.in between d.in the middle19.a.hearsb.originates c.datesd.differs20.a.makeb.discoverc.writed.share答案1.b2.c3.d4.b5.c6.d7.c8.a9.d10.c11.a12.d13.b14.a15.c16.d17.a18.c19.b20.d第二节 阅读理解arobotic surgery is one thing, but sending a robot inside the body to carry out an operation quite another, which has long been a goal of some researchers to produce tiny robotic devices being capable of traveling through the body to deliver drugs or to make repairs without the need for a single cut, the possibility of which has just got a bit closer.however, unlike the plot of one filmwhich featured a microscopic crew and submarine traveling through a scientists bloodstreamthis device could not be inserted into blood vessels(管)because it is too big. while other types of miniature swallowable robots have been developed in the past, their role has mostly been limited to capturing images inside the body. in a presentation this week to the international conference, daniela rus and shuhei miyashita of the massachusetts institute of technology described a robot they have developed that can be swallowed and used to collect dangerous objects accidentally taken in.to test their latest version, dr rus and dr miyashita designed a robot as a battery hunter, which might seem to be an odd task, but more than 3,500 people in america alone, most of them children, swallow the tiny button cells used in small electronic devices by accident every year. to start with, the researchers created an artificial esophagus(食道)and stomach made out of silicone(硅胶). it was closely modeled on that found in a pig and filled with medical liquid; the robot itself is made from several layers of different materials, including pig intestine(肠), and contains a little magnet. this is folded up and encased in a 10mm27mm capsule of ice. once this reaches the stomach the ice melts and the robot unfolds which is moved and guided with the use of a magnetic field outside the body. in their tests, the robot was able to touch a button battery and draw it with its own magnet, and during dragging it along, the robot could then be directed towards the intestines where it would eventually be gotten rid of through the anus(肛门). after it, the researchers sent in another robot loaded with medication to deliver it to the site of the battery burn to speed up healing.the artificial stomach being transparent on one side, the researchers were able to see the batteries and visually control the robots. if not, that will require help with the help from imaging system, which will be a bit more of a challenge, but dr rus and dr miyashita are determined to succeed.1.according to the passage, the robot device will probably be able to.a.travel through a scientists bloodstreamb.photograph the body to convey to the doctorc.enter the body to deliver drugs or make repairsd.operate on a person outside the body completely 2.we learn from paragraph 3 that.a.the researchers did the experiment on a chosen animalb.the robot took necessary drugs besides a little magnetc.digesting the swallowed batteries is difficult for childrend.the actual size of the robot may be larger than the capsule of ice3.what may the experiment mean to the medical world?a.the surgeries will cost patients much money.b.patients will suffer less for some surgeries. c.fewer children will swallow the button cells.d.a robot will be invented traveling blood vessels.4.which can be the most suitable title for the passage?a.an experiment on robotb.tiny robot, significant role c.the fantastic robotic voyaged.the exploration of robot technology答案1.c2.d3.b4.cbno one has a temper naturally so good, that it does not need attention or cultivation, and no one has a temper so bad, but that, by proper cultivation, it may become pleasant. one of the best disciplined tempers ever seen, was that of a gentleman who was naturally quick, irritable, rash, and violent; but, by taking care of the sick, and especially of mentally deranged(疯狂的) people, he so completely mastered himself that he was never known to be thrown off his guard.there is no misery so constant, so upsetting, and so intolerable to others, as that of having a character which is your master. there are corners at every turn in life, against which we may run, and at which we may break out in impatience, if we choose.look at roger sherman, who rose from a humble occupation to a seat in the first congress of the united states, and whose judgment was received with great respect by that body of distinguished men. he made himself master of his temper and cultivated it as a great business in life. there are one or two instances which show this part of his character in a light that is beautiful.one day, after having received his highest honors, he was sitting and reading in his sitting room. a student, in a room close by, held a looking glass in such a position as to pour the reflected rays of the sun directly in mr. shermans face. he moved his chair, and the thing was repeated. a third time the chair was moved, but the looking glass still reflected the sun in his eyes. he laid aside his book, went to the window, and many witnesses of the rude behavior expected to see the ungentlemanly student severely punished. he raised the window gently, and thenshut the window blind!i can not help providing another instance of the power he had acquired over himself. he was naturally possessed of strong passions, but over these he at length obtained an extraordinary control. he became habitually calm and self-possessed. mr. sherman was one of those men who were not ashamed to maintain the forms of religion in their families. one morning he called them all together as usual to lead them in prayer to god. the “old family bible” was brought out and laid on the table.mr. sherman took his seat and placed beside him one of his children, a child of his old age. the rest of the family were seated around the room, several of whom were now grown-ups. besides these, some of the tutors of the college were boarders in the family and were present at the time. his aged mother occupied a corner of the room, opposite the place where the distinguished judge sat.at length, he opened the bible and began to read. the child who was seated beside him made some little disturbance, upon which mr. sherman paused and told him to be still. again he continued but again he had to pause to scold the little offender, whose playful character would scarcely permit him to be still. at this time he gently tapped the childs ear. the blow, if blow it might be called, caught the attention of his aged mother, who now with some effort rose from the seat and tottered across the room. at length, she reached the chair of mr. sherman, and in a moment, most unexpectedly to him, she gave him a blow on the ear with all the force she could gather. “there,” said she, “you strike your child, and i will strike mine.”for a moment, the blood was seen mounting to the face of mr. sherman. but it was only for a moment and all was calm and mild as usual. he paused; he raised his glasses; he cast his eyes upon his mother;again they fell upon the book from which he had been reading. not a word escaped him; but again he calmly pursued the service, and soon sought in prayer an ability to set an example before his household which should be worthy of their imitation. such a victory was worth more than the proudest one ever achieved on the field of battle.5.the followin
