I compared so me of the exercises and drills that we put ourselves through in order to learn a language to the various ingredients that go in to baking a loaf of fresh bread.Real language learning takes place in human relationships. N o one sits down and eats a cup of flour, even if he is hungry a nd in a hurry. You don’t become bilingual (双语的) by learning lists of vocabulary. You don’t become a speak er of a language by memorizing verb conjugations (动词的词形变化) and agreement rules. You become bilingual by entering a community that uses that other language as its primary mean s of communication.I am not suggesting that we can make bread without ingredie nts. Flour is necessary, as are yeast, salt, water and other ing redients. Vocabulary is part of any language and will have to be learned. Grammatical rules exist in every language and ca nnot be ignored. But merely combining the appropriate ingredients in the recommended proportions does not result in bread . At best, you only end up with a ball of dough (面团).In order to get bread, you have to apply heat to the dough. An d in language learning, that heat comes from the community. Anyone who has learned a second language has experienced that heat. It creeps up your neck when you ask the babysitter , “Have you already been eaten?” when you meant to say, “H ave you already eaten?” When you try to say something quite innocent and the whole room bursts into laughter, you are exp eriencing the heat that turns raw dough into good bread. Rem ember the old saying, “If you can’t stand the heat, get out of th e kitchen?” This is where language learning often breaks dow n because we find the heat uncomfortable and we stop the ba king process. In other words, we can’t stand the heat, so we g et out of the kitchen.However, the language learner who stays in the kitchen——in the heat until the combined ingredients are thoroughly trans formed will enjoy the richness of a quality loaf of bread. He sai d that he did not “get out of the kitchen” at the critical moment when the oven seemed too hot. The dedicated language learn er knows that becoming bilingual cannot be achieved without t he heat!24. The passage is mainly about________.A. how we can make baking bread with various IngredientsB. how to become bilingual by communicating with othersC. what an important role “heat” plays in learning a languageD. what a high quality of bread you may achieve in the kitchen25. You can become a speaker of a language by_______.A. bearing millions of words and expressions in your mindB. using the language to communicate with those around youC. knowing verb conjugations and grammatical rulesD. saying something innocent to be laughed at by others26. What is the purpose of illustration of the example——you ask the babysitter, “Have you already been eaten?” when you meant to say, “Have you already eaten?” ?A. To prove that you are sure to make some mistakes when y ou enter a community.B. To show that you should combine the ingredients in the rec ommended proportions.C. To prove that you may experience "heat" from the commun ity in language learning.D. To indicate that being bilingual calls for your courage, confi dence and perseverance.27. According to the passage, which of the following is NOT the necessity of baking bread and learning language?A. Wonderful skills.B. Various ingredients.C. Appropriate proportions.D. Uncomfortable heat.C【黑龙江省2018届普通高等学校招生全国统一考试仿真模拟(八)英语试题】Mandara seemed to know something big was about to happe n. So she let out a yell, caught hold of her 2-year-old daughter Kibibi and climbed up into a tree. She lives at the National Zoo in Washington D.C..And on Tuesday, August 23rd, witnesses said she seemed to sense the big earthquake that shook much of the East Coast before any humans knew what was going on. And she’s not th e only one. In the moments before the quake, an orangutan (猩猩) let out a loud call and then climbed to the top of her shelte r.“It’s very different from their normal call,” said Brandie Smith, t he zookeeper. “The lemurs (monkey like animals of Madagas car) will sound an alarm if they see or hear something highly u nusual.”But you can’t see or hear an earthquake 15 minutes before it happens, can you? Maybe you can——if you’re an animal.“Animals can hear above and below our range of hearing,” sai d Brandie Smith. “That’s part of their special abilities. They’re more sensitive to the environment, which is how they survive.”Primates w eren’t the only animals that seemed to sense the q uake before it happened. One of the elephants made a warnin g sound and a huge lizard (蜥蜴) ran quickly for cover. The flamingoes (a kind of birds) gath ered before the quake and stayed together until the shaking st opped.So what kind of vibrations (震动) were the animals picking up in the moments before the qu ake? Scientist Susan Hough said earthquakes produce two ty pes of waves——a weak “P” wave and then a much stronger “S” wave. The “P”stands for “primary”. And the “S” stands for “secondary”. She t hinks the “P” wave might be what sets the animals off.Not all the animals behaved unusually before the quake. For example, Smith said the zoo’s giant pandas didn’t jump up unt il the shaking actually began. But many of the other animals s eemed to know something was coming before it happened. “I’m not surprised at all,” Smith said.28. Why did Mandara act strangely one day?A. Because it sensed something unusual would happen.B. Because its daughter Kibibi was injured.C. Because it heard an orangutan let out a loud callD. Because an earthquake had happened.29. According to Brandie Smith,_____________.A. many animals hearing is sharpB. earthquakes produce two types of wavesC. primates usually gather together before a quakeD. humans can also develop the ability to sense a quake30. Which animal seems unable to sense quake?A. A giant panda.B. A flamingo.C. A lemur.D. A lizard.31. What is the best title for the passage?A. How animals survive a quakeB. How animals differ from humansC. How animals behave before a quakeD. How animals protect their young in a quakeD【河南省新乡市2018-2019学年高一上学期期中考试英语试题】Born in Detroit, Michigan, on January 10th, 1928. Philip Levin e was formally educated in the Detroit public school system. A fter graduation from university, Levine worked a number of ind ustrial jobs, including the night work in factories, reading and writing poems in his off hours. In 1953, he studied at the Univ ersity of Iowa. There, Levine met Robert Lowell and John Berr yman, whom Levine called his “one great guide”.About writing poems, Levine wrote: “I believed even then that if I could change my experience into poems I would give it the value and honor that it did not begin to have on its own. I tho ught too that if I could write about it, I could come to understa nd it: I believed that if I could understand my life——or at least the part my work played in it——I could write it with some degree of joy, something obviously missing from my life.”Levine published (出版) his first collection of poems. On the Edge in 1961, followe d by Not This Pig in 1968. Throughout his life Levine publishe d many books of poems, winning many prizes. A review said: “Levin e writes poems about the bravery of men, physical labo r, simple pleasures and strong feelings, often set in working-class Detroit or in central California, where he worked or lived.”He taught for many years at California State University, Fresn o and served as Distinguished Poet in Residence for the Crea tive Writing Program at New York University. After retiring fro m teaching, Levine divided his time between Brooklyn, New Y ork, and Fresno, California, until his death on February 14th, 2015. His final poem collection, The Last Shift, as well as a co llection of essays (短文) and other writings, My Lost Poets: A Life in Poetry, were p ublished in 2016.32.

Kelsey Zwick found Jason Kunselman,the stranger who offered his first class seat to her. Kunselman said that it just seemed like the right thing to do at the moment.24.What did Kelsey Zwick travel on a plane for?A.Her baby's illness.B.A holiday in Philadelphia.C.Her new settlement.D.A friend's birthday party.25.Why did the stranger change seats with Zwick?A.To help more passengers.B.To stay with his friends.C.To make her comfortable.D.To enjoy a good view.26.How did Zwick feel about the stranger's act?A.Disappointing.B.Surprising.C.Satisfying.D.Moving.27.What can be the best title for the text?A.A flight to Philadelphia.B.An act of kindness.C.A message on Facebook.D.A traveling experience.CLunch is a part of Chinese culture.When I'm back home in England,I often miss Chinese lunch.At home,at work,at school,English lunchtime is far from a formal meal of the day.It seems that we can't wait to finish lunch as quickly as possible. People working in the office take out packed sandwiches that are not delicious.Work canteens(餐厅)are crowded with people too busy to eat,rushing to the checkout(收银台)with something in hand so that they can quickly eat up on the way to another meeting.A lot of work in England leaves little time to have our meals and enjoy them.Perhaps this is why so many of us hold such unhealthy relationships with food.The way we plan our days in England shows we don't care about mealtimes.Meetings, lectures,interviews and so on are all planned from 12:00 a.m.to 2:00 p.m.In Beijing lunch often starts from 11:30 a.m.and lasts until 1:00p.m.And owners of many shops gather in small groups to share a meal,which is hardly seen in England.I have never experienced such a culture where finding time to eat is so important.In China,food is shared and the time is enjoyed as a moment of get-together in busy days. This is a value and practice we should hold in our lives in England.In China food is not only a necessity(必需品),but also a time for get-together with friends and family,and I love it.28.Why can't most English people enjoy their lunch?A.They think British food is terrible.B.They are anxious to go shopping.C.They are too busy with work.D.They have much housework.29.Which does the author like most about Chinese lunch?A.Its atmosphere.B.Its taste.C.Its price.D.Its kinds.30.What can we learn from Paragraph 3?A.English people like to get together in groups.B.English lunchtime lasts one and a half hours.C.English people never experience Chinese culture.D.English people don't take mealtimes seriously.31.What is mainly talked about in the text?A.The best way to experience Chinese lunch.B.Lunch differences between China and England.C.Suggestions of enjoying English culture.D.The stressful lifestyles of English people.DChina successfully launched the Chang'e-4 at 2:23 a.m.on December 8,2018, which separated from the rocket 25 minutes after it lifted off.Its key task is to explore the far side of the Moon and search for radio signals(信号)from the space's very early days.It will be able to observe(观测)both the Earth and the far side of the Moon.When the night falls,the Moon rises.The Moon is the Earth's natural satellite (星)and people have been admiring the Moon for thousands of years.Over the past years,many countries including the US and Russia have sent spaceships and astronauts,but the far side is not visible from the Earth and has never been explored by humans.Lifting off from Xichang Satellite Launch Center,China'sChang'e-4 could be the first ever to land on the far side of the Moon.We are about to know more about the Moon.To explore this unknown area,the first key challenge was to make sure of the communication with the scientists on Earth.On May 21,China launched Chang'e-4's relay satellite, Queqiao.In a Chinese folk story, Queqiao is a bridge which helps Zhinu,the seventh daughter of the Goddess of Heaven,meet her husband,Niulang,whois separated from her by the Milky Way.Besides carrying out three scientific projects developed by three Chinese universities,the relay satellite will serve as a stage for international cooperation (合作).This is not only the Long March Rocket's 275th launch,but also the Long March-4C rocket's first launch at the Xichang Satellite Launch Center.32.China launched the Chang'e-4 mainly toA.collect astronauts from the space stationB.look for life on other planetsC.explore the hidden side of the moonD.send some astronauts to the moon33.What does the underlined word"visible"probably mean in Paragraph 2?A.Seen.B.Found.C.Attacked.D.Ruined.34,What was the most difficult thing in exploring the far side of the moon before?A.The rockets were not powerful enough.B.There was not enough money for it.C.There were no ways to deal with bad weather.D.It was hard to communicate with the earth.35.What does the text want to tell readers?A.China is the most powerful nation.B.The successful launch of Chang'e-4.C.China makes great progress in science.NS.D.The Xichang Satellite Launch Center.第二节(共5小题:每小题2分,满分10分)根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。
