Reading prehension （35%）Directions: Read the following passages Each passage is followed by several questions or unfinished statements. For each of them there are four choices marked A,B,C and D. Choose the one that fits best according to the information given in the passage you have just read.(A)A thief who dropped a winning lottery ticket （彩票）at the scene of his crime has been given a lesson in honesty. His victim, who picked up the ticket, then claimed the £25,000 prize, managed to trace him, and handed over the cash. The robbery happened when maths professor Vinicio Sabbatucci, 58, was changing a tyre on an Italian motorway. Another motorist, who stopped “to help”, stole a suitcase from his car and drove off. The professor found the dropped ticket and put it in his pocket before driving home to Ascoli in eastern Italy.Next day, he saw the lottery results on TV and, taking out the ticket, realized it was a winner. He claimed the 60 million lire (里拉) prize. Then he began a battle with his conscience. Finally, he decided he could not keep the money despite having been robbed. He advertised in newspapers and on radio, saying: “I’m trying to find the man who robbed me . I have 60 million lire for him—a lottery win. Please meet me. Anonymity (匿名) guaranteed.”Professor Sabbatucci received hundreds of calls from people hoping to trick him into handing them the cash. But there was one voice he recognized—and he arrangedto meet the man in a park. The robber, a 35-year-old unemployed father of two, gave back the suitcase and burst into tears. He could not believe what was happening. “Why didn’t you keep the money? ”he asked. The professor replied: “I couldn’t because it’s not mine. ” Then he walked off spurning the thief’s offer of a reward. 65. The sentence “Then he began a battle with his conscience.” in paragraph 2 implies all of the following EXCEPT that ________.A. he knew what he should do as soon as he saw the lottery resultsB. he hesitated about keeping the money for some timeC. he thought for a moment of avenging himself on the robberD. he came to realize that honesty is more important than money66. Hundreds of people phoned professor Sabbatucci because they ______.A. waned to make fun of himB. hoped to get the moneyC. knew who the robber wasD. lost the lottery ticket67. The word “spurning” in th e last sentence can be replaced by _______.A. acceptingB. claimingC. rejectingD. cancelling68. If the story appears in a newspaper , the best title might be ______.A. A Thief’s Lucky DayB.A Popular Maths ProfessorC. A Magic LotteryD.A Reward to Honesty(B)The science of physics today is as current as the morning newspaper. Indeed, as a result of new advances in physics and their rapid application to inventions designed to satisfy man’s wants. Th e world itself has been changing rapidly. Space technology, industrial technology, and the technology of the home, the farm, the office, the bank, and the department store have all been revolutionized.Clearly, every grown-up today would understand the world he lives in much better if he knew something about physics. Whether it be congress (美国国会) voting huge sums of money for new warships, space exploration, or atomic energy; the office staff learning to use a new puter; son Bobby wanting to know about going to the moon; or the housewife learning to operate a new electric stove, physics seems to be everywhere.Teachers in thousands of schoolrooms in America are trying to municate some of the excitement and importance of these new developments to their students. They know that some of their eager students will someday be scientists and will themselves then contribute(贡献) to the development of new knowledge or its application to new things.But in any case, they can be sure that if they bring a knowledge of science (any science )to their students in meaningful and stimulating ways, they have contributed much to helping each one live a more meaningful life.69. The application of new advances in physics to inventions ______.A. may solve all the problems in teachingB. can help people understand the meaning of lifeC. is intended to meet people’s needsD. makes people understand the voting rules of the Congress70. According to the passage, many American teachers are making efforts to do all of the following EXCEPT______.A. stimulating their students’ curiosity in physicsB. making their students understand the importance of physicsC. giving their students the information of new advances in scienceD. creating excitement about physical education among their students71. The word “themselves” in the third paragraph refers to _____.A. some of the eager studentsB. the students in the classroomC. the teachers giving lessonsD. all the scientists in physics72. The first two paragraphs of the passage mainly tell us about ______.A. new advances in physicsB. the use of physics in our lifeC. the science of physicsD. modern developments in science(C)CAR HIREHiring a self-drive car really adds to the enjoyment of your holiday. There are so many interesting places to visit, and if you enjoy seeing just more than the city centre1). The minimum rental period at these special low prices is three days. For prices for periods of one or two days only see our representative at the hotel.2). Car hire must be booked six weeks or more before arrival in London to guaranteea car. But if you have been unable to make a booking in advance please see our representative at the hotel who may still be able to help you.3). The car types specified on the sheet are examples of the type of vehicles available in each price range, but a particular car cannot be guaranteed.Upon delivery the driver(s) will be asked to sign the car hire pany’s Conditions of Hire. If you decided to hire a car, just fill in the booking form and return it to us. A booking fee of ￡12 as part of the car hire cost is required.Should you be forced to cancel your car hire booking after payment in full (two weeks before date of hire), a cancellation charge of ￡12 will be made.73. What costs is a car hirer responsible for?A. Insurance against damage to the car.B. Insurance against injury to the driver.C. The cost of maintenance of the car.D. The cost of repairs to the car.74.

The cost of oil ______.A. has to be paid by the driverB. should be charged to the panyC. is covered by the insurance paymentD. can be reclaimed by the driver(D)Imagine that the genome (基因组) is a book. The book consists of 23 chapters with thousands of stories made up of paragraphs, words and letters on different levels. There are one billion words in the book, which makes it longer than 5,000 volumes the size of this book. or as long as 800 Bibles. If I read the genome out to you at the rate of one word per second for eight hours a day, it would take me a century. If I wrote out the human genome, one letter per millimeter, my text would be as long as the River Danube. This is an enormous document. a huge volume, a book of great length, and it all fits inside the extremely small nucleus(核) of a tiny cell that fits easily upon the head of a pin.The idea of the genome as a book is not, strictly speaking , even a metaphor(比喻). It is true to a great extent. A book is a piece of digital information, written in one-directional form and defined by a code that translates a small alphabet of signs into a large dictionary of meanings through the order of their grouping. So is genome. The only plication is that all English books read from left to right, while some parts of the genome read from left to right, and some from right to left, though never both at the same time.While English books are written in words of different lengths using twenty-six letters, genomes are written entirely in three-letter words, using only four letters. And instead of being written on flat pages, they are written on long chains of DNA molecules (分子). The genome is a very clever book, because in the right conditions it can both photocopy itself and read itself.76. How do human genomes read according to the passage?A. Only from left to right.B. Only from right to left.C. From both directions at the same time.D. From one direction at a time.77. We can learn from the passage that the human genome ______.A. is as long as the River DanubeB. can be easily placed on the head of a pinC. is coded with an alphabet of four lettersD .is smart enough to read and take photos of itself78. It can be concluded that the passage is mainly written for ______.A. specialists in the fieldB. general readersC. natural scientistsD. readers with academic background79. The real purpose of the author’s parison of the genome to a book is ____.A. to focus on the differences between the twoB. to lay emphasis on the similarities between the twoC. to simplify the concept of the human genomeD. to give an exact description of the human genome(E)Direction:Read the following passage and choose the most suitable heading from the list A—F for each paragraph. There is one extra heading which you do not need.Mud, a simple mixture of earth and water, has been used to build houses and other buildings for thousands of years. More than half the world’s population, particularly in the poorer countries of the world, still lives in mud buildings. In more industrialized countries, however, it was replaced a long time ago by more modern building materials such as concrete and steel.80. __________All that may soon change. Experts in Britain have discovered that mud is actually an ideal building material. They recently examined some of the 100,000 mud buildings in Britain and were astonished at what they found. Most of the buildings were built between 1500 and 1850, but in spite of their age they are still in very good condition. The walls of the houses are still smooth, firm, and strong. Also, the mud helps to keep the temperature and humidity inside the houses constant, which is healthier for the people living there. It keeps the rooms warm in the winter and cool even in the heat of midday in the summer. This means cheaper costs both for heating and air-conditioning.81. __________Now, some of the Britain’s building panies are considering replacing modern materials with mud to build houses. For them, one of the biggest advantages of using mud is that it is so cheap. In fact, in most places it would be almost free. Another advantage is that if a building was no longer needed, it could simply be knocked down. As soon as the walls fell to pieces they would turn back into earth. Then the earth could be used again to make more mud buildings. This could be a big advantage as more people realize the importance of recycling and not wasting materials.82. __________There are already some modern mud buildings built in parts of the world. In France there is a whole town, Domaine de Terre, which has been made out of mud. In New Zealand some buildings used for making wine have been built out of mud bricks. The way that the mud controls temperature and humidity makes the buildings very good for storing the wine. New mud buildings do not have to be ugly, simple or small. The town of Sana’a in South Yemen has some mud buildings as high as 11 storeys! 83. __________If you still don’t believe that a mud house would last for a long time, then just think about the Great Wall of China. Most of that was built with mud, and it has been standing for more than a thousand years!第II 卷(共40分)I.

2019高考语文模拟试卷与答案(1)
2019 年高考语文模拟试卷及答案（原创）一、现代文阅读（36 分）（一）论述类文本阅读（本题共 3 小题，9 分）阅读下面的文字，完成1—— 3 题文艺是一种表现而不是一种卖弄。
表现的理想是文情并茂，“充实而有光辉” ，虽经苦心雕琢，却是天衣无缝，自然熨贴，不现勉强作为痕迹。
一件完美的艺术品像一个大家闺秀，引人注目而却不招邀人注目，举止大方之中仍有她的贞静幽闲，有她的高贵的身份。
艺术和人一样，有它的品格，我们常说某种艺术品高，某种艺术品低，品的高低固然可以在多方面见出，最重要的仍在作者的态度。
品高的是诚于中，形于外，表里如一的高华完美。
品低的是内不充实而外求光辉，存心卖弄，像小家娼妇涂脂抹粉，招摇过市，眉挑目送的样子。
文艺的卖弄有种种方式。
最普遍的是卖弄词藻，只顾堆砌漂亮的字眼，显得花枝招展，绚烂夺目，不管它对于思想情感是否有绝对的必要。
从前骈俪文犯这毛病的最多，现在新进作家也有时不免。
其次是卖弄学识。
文艺作者不能没有学识，但是他的学识须如盐溶解在水里，尝得出味，指不出形状。
有时饱学的作者无心中在作品中流露学识，我们尚不免有“学问汩没性灵”之感，至于有意要卖弄学识，如暴发户对人夸数家珍，在寻常人如此已足见趣味低劣，在文艺作品中如此更不免令人作呕了。
过去中国文人犯这病的最多，在诗中用僻典，谈哲理，写古字，都是最显著的例。
新文学作家常爱把自己知道比较清楚的材料不分皂白地和盘托出，不管它是否对于表现情调、描写人物或是点明故事为绝对必需，写农村就把农村所有的东西都摆进去，写官场也就把官场所有的奇形怪状都摆进去，有如杂货店，七零八落的货物乱堆在一起，没有一点整一性，连比较著名的作品如赛珍珠的《大地》，吴趼人的《二十年来目睹之怪现状》之类均不免此病，这也还是卖弄学识。
第三是卖弄才气。
文艺作者固不能没有才气，但是逞才使气，存心炫耀，仍是趣味低劣。
像英国哲学家休谟和法国诗人魏尔兰所一再指示的，文学不应只有“雄辩”（eloquence ），而且带不得雄辩的色彩。

He drove a white Ford car. Who was he ? The police found ＂Harvey Lowmeyer's ＂gun and ＂John Willard's ＂shirt, and then the white car. It was ＂Eric Starvo Galt's＂car. So what was this man's real name? The marks on the shirt and the car sent the F. B. I. to Los Angeles. 300 detectives questioned people. At last one found a photograph of ＂Galt＂. Then detectives in Atlanta found a fingerprint. It was on a map in ＂Galt＇s＂room in a small hotel. One fingerprint was enough.James Earl Ray's fingerprint was already on the F. B. I. cards. The police watched railway stations, hotels and airports. 3000 detectives were trying to find Ray---without success.The Canadian police were helping, too. They looked at 240,000 photographs in their Passport Office. Then they found one of ＂Ramon George Sneyd＂. ＂We gave this man a passport last month,＂they said. ＂He went to London on 2nd May. ＂The man was wearing thick glasses, but he looked like Ray.

Which was the murderer's real name ?(A) Ramon George Sneyd. (B) James Earl Ray(C) Eric Starvo Galt (D) John WillardDHow can we get rid of garbage() ? Do we have enough energy sources to meet our future energy needs?These are two important questions that many people are asking today. Some people think that men might be able to solve both problems at the same time. They suggest using garbage as an energy source.For a long time people buried garbage or dumped it on empty land. Now empty land is scarce. However, more and more garbage is produced each year, but garbage can be a good fuel to use. The things in garbage do not look like coal, petroleum, or natural gas: but they are chemically similar to these fossil fuels(). As we use up our fossil-fuel supplies, we might be able to use garbage as an energy source.Burning garbage is not a new idea. Some cities in Europe and the United States have been burning garbage for years. The heat that is produced by burning garbage is used to boil water. The steam that is produced is used to make electricity or to heat nearby buildings. In Paris, France, some power plants burn almost 2 million metric tons of the city's garbage each year. The amount of energy produced is about the same as would be produced by burning almost a half million barrels of oil.But there are problems in using garbage as a fuel. Garbage that burns easily, such as food scraps and paper, must be separated from metals, glass, and other materials that do not burn easily. This separation process is normally costly. Another problem is that burning garbage can pollute the air. Our fossil fuel supplies are limited. Burning garbage might be one kind of energy source that we can use to help meet our energy needs. This method could also reduce the amount of garbage piling up on the earth.82. Which of the following is NOT fossil fuel?(A) Natural gas (B) Petroleum (C) Coal (D) Tide83. People used to depose garbage by ______.(A) turning garbage into useful fossil fuel(B) burning garbage or dumping it on empty land(C) separating garbage into three types(D) shipping garbage into sea or ocean84. Why should we use garbage as an energy source?(A) Because our fossil fuel supplies are limited(B) Because garbage is more useful than fossil fuels(C) Because burning garbage can save a lot of money for us(D) Because empty land is getting more and more scarce.85. What do you think the next paragraph will talk about?(A) Some other methods of turning garbage into treasure(B) Some other benefits we can get from burning garbage(C) How much garbage we can make use of in the world(D) How to separate food scraps and paper from garbage that do not burn easily.第二卷（共40分）VI.
