unit 5 meeting your ancestors reading课时作业passage 1(2017新课标全国卷ii)terrafugia inc. said monday that its new flying car has completed its first flight, bringing the company closer to its goal of selling the flying car within the next year. the vehicle named the transition has two seats, four wheels and wings that fold up so it can be driven like a car. the transition, which flew at 1,400 feet for eight minutes last month, can reach around 70 miles per hour on the road and 115 in the air. it flies using a 23-gallon tank of gas and burns 5 gallons per hour in the air. on the ground, it gets 35 miles per gallon.around 100 people have already put down a $10,000 deposit to get a transition when they go on sale, and those numbers will likely rise after terrafugia introduces the transition to the public later this week at the new york auto show. but dont expect it to show up in too many driveways. its expected to cost $279,000.and it wont help if youre stuck in traffic. the car needs a runway. inventors have been trying to make flying cars since the 1930s, according to robert mann, an airline industry expert. but mann thinks terrafugia has come closer than anyone to making the flying car a reality. the government has already permitted the company to use special materials to make it easier for the vehicle to fly. the transition is now going through crash tests to make sure it meets federal safety standards.mann said terrafugia was helped by the federal aviation administrations decision five years ago to create a separate set of standards for light sport aircraft, which are lower than those for pilots of larger planes. terrafugia says an owner would need to pass a test and complete 20 hours of flying time to be able to fly the transition, a requirement pilots would find relatively easy to meet.28. what is the first paragraph mainly about?a. the basic data of the transition. b. the advantages of flying cars.c. the potential market for flying cars. c. the designers of the transition.29. why is the transition unlikely to show up in too many driveways?a. it causers traffic jams. b. it is difficult to operate.c. it is very expensive. d. it burns too much fuel.30. what is the governments attitude to the development of the flying car?a. cautious b. favorable.c. ambiguous. d. disapproving.31. what is the best title for the text?a. flying car at auto show b. the transitions first flightc.pilots dream coming true d. flying car closer to reality【文章大意】本文是一篇说明文。主要介绍了terrafugia公司研制出了飞车，试飞成功，预计将于明年进行销售。本文主要对飞车的历史由来及其构架进行了介绍。29.c 【解析】细节理解题。根据“but dont expect

aircraf”可知，政府对于飞车的研发是比较支持的。故选b。31.d 【解析】标题归纳题。浏览全文，主要从飞车的试飞成功、飞车的构架以及多年以前人们对飞车的设想至今成为现实展开说明。故选d。passage2(2017新课标全国卷iii)after years of heated debate, gray wolves were reintroduced to yellowstone national park. fourteen wolves were caught in canada and transported to the park. by last year, the yellowstone wolf population had grown to more than 170 wolves.gray wolves once were seen here and there in the yellowstone area and much of the continental united states, but they were gradually displaced by human development. by the 1920s, wolves had practically disappeared from the yellowstone area. they went farther north into the deep forests of canada, where there were fewer humans around.the disappearance of the wolves had many unexpected results. deer and elk populations major food sources (来源) for the wolf grew rapidly. these animals consumed large amounts of vegetation (植被), which reduced plant diversity in the park. in the absence of wolves, coyote populations also grew quickly. the coyotes killed a large percentage of the parks red foxes, and completely drove away the parks beavers.as early as 1966, biologists asked the government to consider reintroducing wolves to yellowstone park. they hoped that wolves would be able to control the elk and coyote problems. many farmers opposed the plan because they feared that wolves would kill their farm animals or pets. the government spent nearly 30 years coming up with a plan to reintroduce the wolvers. the u.s. fish and wildlife service carefully monitors and manages the wolf packs in yellowstone. today, the debate continues over how well the gray wolf is fitting in at yellowstone. elk, deer, and coyote populations are down, while beavers and red foxes have made a comeback. the yellowstone wolf project has been a valuable experiment to help biologists decide whether to reintroduce wolves to other parts of the country as well.28. what is the text mainly about?a. wildlife research in the united states.b. plant diversity in the yellowstone area.c. the conflict between farmers and gray wolves.d. the reintroduction of wolves to yellowstone park.29. what does the underlined word displaced in paragraph 2 mean?a. tested.b. separated.c. forced out.d. tracked down.30. what did the disappearance of gray wolves bring about?a. damage to local ecology. b. a decline in the parks income.c. preservation of vegetation. d. an increase in the variety of animals.31. what is the authors attitude towards the yellowstone wolf project?a. doubtful. b. positive. c. disapproving. d. uncaring.【文章大意】本文是一篇说明文，介绍了美国黄石公园重新引进灰狼的事情。人类活动的影响使灰狼的数量逐渐减少，鹿群数量逐渐增加，从而导致植被被大量破坏。30. a 【解析】推理判断题。根据第三段的内容可知，灰狼的减少造成了鹿群的增多，从而植被遭到了破坏；造成了土狼数量的快速增长，它们猎杀了大量的赤狐，赶走了海狸，由此可推断出灰狼的消失导致了当地生态平衡被破坏。31. b 【解析】推理判断题。根据文章末段的最后一句可知，作者认为引进灰狼的项目是很有价值的实验，因此可推知作者对这一举措持肯定的态度。passage

be a social activity. think of the people who belong to book groups. they choose books to read and then meet to discuss them. now, the website bookc turns the page on the traditional idea of a book group.members go on the site and register the books they own and would like to share. bookcrossing provides an identification number to stick inside the book. then the person leaves it in a public place, hoping that the book will have an adventure, traveling far and wide with each new reader who finds it. bruce pederson, the managing director of bookcrossing, says, “the two things that change your life are the people you meet and books you read. bookcrossing combines both.” members leave books on park benches and buses, in train stations and coffee shops. whoever finds their book will go to the site and record where they found it. people who find a book can also leave a journal entry describing what they thought of it. e-mails are then sent to the bookcrossers to keep them updated about where their books have been found. bruce pederson says the idea is for people not to be selfish by keeping a book to gather dust on a shelf at home. bookcrossing is part of a trend among people who want to get back to the “real” and not the virtual(虚拟). the site now has more than one million members in more than one hundred thirty-five countries.29. why does the author mention book groups in the first paragraph? a. to explain what they are. b. to introduce bookcrossing.c. to
