He's making the trip to encourage the government and others to value and protect Indonesia's rainforests.Medi Bastoni is 43 years old. He is an Indonesian. Indonesia is a large country in the world formed by a group of islands. There are over 16, 000 islands there,and most of them are covered with rainforests. But on Java, where Mr. Bastoni lives, far more forests have been cleared.Mr. Bastoni believes it's important to protect forests from being cut down, and to restore (恢复) them when they have been destroyed. Near his home, Mount Wilis is now being restored, but Mr. Bastoni wants to make the protection continue. That's how he came up with the idea of the 435-mile walk.And walking backwards? Mr. Bastoni wants Indonesians to look back at their past. Walking backwards is a good way to get attention. Right now, Mr. Bastoni's backward walk is pretty big news in Indonesia.Mr. Bastoni is wearing a frame(框架)that supports a large mirror in front of him, above his head. This allows Mr. Bastoni to look behind him while walking backwards. Besides, Mr. Bastoni is carrying a backpack with some clothes and a little food. He is planning on buying more meals from restaurants along the way. He has been sleeping at police stations, security posts, and even strangers homes during the trip. His plan is to cover about 19 miles a day. In early August he was in Sragen -- about 100 miles from his home. It's not clear whether Mr. Bastoni is still on track to arrive in Jakarta by August 17.4.

The importance of rainforests to Indonesia.C. A trip to recall history and attract attention.D. A walking backwards trip to save rainforests.CNewspapers in Great Britainvarygreatly in their ways of carrying the news. There are serious papers for those who want to know about important happenings everywhere, both at home and abroad. There are popular newspapers for those who prefer entertainment to information.The London newspaper that is best known outside Great Britain is probably the Times. It began in 1785, and has a high reputation for believable news and serious opinions on the news. It calls itself an independent paper, which means that it does not give its support to a particular political party. Its leading articles give the opinions of the editors, not those of the owners of the paper.Letters to the editor are printed in the newspaper. These parts of the Times are always interesting. Most of the letters are serious subjects. But from time to time there will be long letters on the subject which is not at all serious, perhaps on a new fashion of dress, or the bad manners of the young people, compared with manners of thirty years ago.8. If you want to get pleasure, please buy yourself _________.A. a serious newspaperB. foreign newspaperC. any independent paperD. a popular newspaper9. The Times has been famous to outside Great Britain for ________ years.A. 19B. 85C. 236D. 22910. The Times is an independent paper because ________.A. it supports no political partiesB. it is not controlled by the British GovernmentC. it gives special support to all the political parties.D. the editor’s opinions are not examined by the owners of the paper11. The underlined word “vary” in the passage probably means “_________”.A. improveB. compete with each otherC. are differentD. keep in touch with each otherDWhat about your emotions? How do they help you to understand what you are reading?In Jane Yolan'sOwl Moon,a girl explores with her father on a snowy night. She longs for this special night.And she's amazed when she sees an owl.Have you felt longing before? Amazement? Well, if you have, it helps you have a sense of agreement. When we can put ourselves inside a story we can understand it better. Our brain tells us,"Oh, this girl's experience is a bit like mine."And boom! We can relate to her.But this skill is not born in us.So young kids have to learn it.Pictures and images help young readers to understand and recognize feelings.Readers feel joy when seeing the smiling faces of friends.They feel fear when turning the page to find a scary monster. They are just pictures,but the feelings are real. This skill, to understand the thinking and feeling of others, is what researchers call "theory of mind".For example, think about the faces of people and animals in stories. The Big Bad Wolf's scary teeth. The 'o' shape of a surprised character's mouth. Or big, wide eyes like the girl inOwl Moon.By noticing the faces,readers can start to figure out what it feels like to be that character.And that helps to figure out how people feel and think in real life.But most young readers don't go into deep,scary woods.And some may not go to the beach or play basketball.In the bookYo!Yes?two kids meet and play ball. The kids start the story on opposite pages.But as the story goes on,they get closer until they are together.Some young readers might not play basketball, but they canread the clues on the page to figure out how the kids are feeling.And some readers might not like the game,but they can feel excited for the characters because of how the characters look and move.12. What can we learn from the second paragraph?A.Owl Moontalks about the exploration of the Moon.B. The feeling of"amazement"is a sense of agreement.C. Readers are blessed with the ability to interpret others.D. Readers with similar experience understand the story better.13. Which of the following might help readers develop"theory of mind"?A. True feelings.B. Smiling faces.C. Picture books.D. Reading skills.14. Young readers can go deeper into a story by________.A. tracking the plotB. developing new skillsC. sharing similar hobbiesD. analyzing the background15. What is the text mainly about?A. How thinking influences reading.B. How readers improve reading skills.C. How emotions help enhance reading.D. How kids figure out the clues of stories.第二节(共5小题;每小题2分,满分10分)阅读下面短文,从短文后的选项中选出可以填入空白处的最佳选项。

大夫逄同谏曰:“今夫吴兵加齐、晋,怨深于楚﹑越,名高天下,实害周室,德少而功多,必淫自矜。

为越计,莫若结齐,亲楚,附晋,以厚吴。

吴之志广,必轻战。

是我连其权,三国伐之,越承其弊,可克也。

”勾践曰:“善。

”其后四年。

吴士民罢弊,轻锐尽死于齐﹑晋。

而越大破吴,因而留围之三年,吴师败,越遂复栖吴王于姑苏之山。

吴王使公孙雄肉袒膝行而前,请成越王曰:“孤臣夫差敢布腹心,异日尝得罪于会稽,夫差不敢逆命,得与君王成以归。

今君王举玉趾而诛孤臣,孤臣惟命是听,意者亦欲如会稽之赦孤臣之罪乎?”勾践不忍,欲许之。

范蠡曰:“会稽之事,天以越赐吴,吴不取。

今天以吴赐越,越其可逆天乎?且夫君王蚤朝晏罢,非为吴邪?谋之二十二年,一旦而弃之,可乎?且夫天与弗取,反受其咎。

君忘会稽之厄乎?”勾践曰:“吾欲听子言,吾不忍其使者。

”范蠡乃鼓进兵,曰:“王已属政于执事,使者去,不者且得罪。

”吴使者泣而去。

勾践怜之,乃使人谓吴王曰:“吾置王甬东,君百家。

”吴王谢曰:“吾老矣,不能事君王!”遂自杀。

(4分) 意境是人们在审美活动中,用心灵去观照外界对象,并在把握和领会对象的基础上,充分展开想像,创造出来的新的意蕴和坑界。

首先,从审美活动的角度看,意境超越了具体的有限的物象、事件、场景,进入无限的时间和空间,从而对整个人生、历史、宇宙获得的一种哲理性的领悟和感受;因而,这种超越性会使审美者从当下的现实中超越出来进入一种自由境界。

其次,人们进行审美活动时,会把此时、此地的情与景和彼时、彼地的情与景,通过时空转换融合在同一个意境中,并使人们摆脱时间和空间的限制和束缚,得到审美的心灵自由。

另外,在审美活动中,作为主体的人与作为客体的审美对象在人的思想意识领域中会创造一个完全独立于眼前的现实世界的审美世界、艺术世界,这种主客统一可以说是所有审美形态共同具有的内涵,而意境的主客统一是最为完整且有特殊含义的,其极致是“物我两忘”。

17.将下列句子组合成语意连贯、合乎逻辑的一段话,并将序号填入横线处。

2019-2020学年滨州市邹平一中高三英语下学期期末试卷及答案解析

2019-2020学年滨州市邹平一中高三英语下学期期末试卷及答案解析第一部分阅读(共两节,满分40分)第一节(共15小题;每小题2分,满分30分)阅读下列短文,从每题所给的A、B、C、D四个选项中选出最佳选项ABob and Sue Harvey spent nine years as resident fellows in a dormitory at Sanford and in their bookVirtual Reality and The College Freshman, they write “The Freshman oftenfaces an identity problem during the first semester.” College is a more pressured environment than it used to be, in part because the academic gap between high school and college has increased. Many college freshmen have never had to make independent decisions about sex, drugs and alcohol. Most don’t know how to manage their time or money. They often feel lonely and overwhelmed, resulting in anxiety and depression.Nancy Corbin, director of clinical service for student-counseling (咨询) services at Iowa State University, says her office is seeing a significant increase in requests for counseling from freshmen who are having trouble making the adjustment to college life. She says older teenagers increasingly lack the skills to deal with personal problems that aren’t easily defined or fixed. And they get homesick but have a hard time admitting it.Parents and high schools can make things easier on freshmen by preparing them differently. For example, by teaching them to budget their hours and dollars. The Harveys think high schools should offer a college-life course. “Parents need to focus more on relationship and personal issues and less on how many sheets and towels to take,” they say. Many homesick freshmen think they’ll be regarded as failures if they come home before Thanksgiving. So parents can help by letting them know they’re welcome to return if they feel the need. In the meantime, parents have to find new ways to keep in touch with their college kids. One of the best ways is e-mail. It’s less unpleasant and less expensive than constant phone calls and is more likely to be answered than a handwritten letter.1. Why is the first semester difficult for freshmen in college?A. Because they often fail in exams.B. Because they lack time and money.C. Because they are too homesick to make new friends.D. Because they have to settle personal issues on their own.2. In the last paragraph, it is suggested that ________.A. parents should stop buying anything for their kidsB. parents should develop a good relationship with their kidsC. parents should be taught how to send e-mails to their kidsD. parents should work with high schools in college-life courses3. Which of the following might be the best title for the passage?A. Hard Life of College FreshmenB. Approaches to Trouble in CollegeC. Freshmen’s Adaptation ProblemsD. A Strange Phenomenon in CollegeBJoshua Nelson, 18, fromMissouri, is graduating fromSt. CharlesWestHigh Schoolthis week and will be attendingSoutheastMissouriStatein the fall. He had saved upmoney to pay for his tuition, but when he received the college's President's Scholarship, he decided to take his savings and donate it to other students in need.“It comes from my family education and faith," Nelson said. "I've always lived by strong principles as far as being a cheerful giver andhaving an open handwhen it comes to giving back so I feel like that really motivated me.”SEMO's President's Scholarship is the school’s most celebrated, and is only awarded to five top students annually. Nelsonsaid he sat down and outlined how a scholarship could work to help future students who need financial assistance for college. Originally the plan was to give away $ 1,000 the one time, but then he met up with his counselor (顾问), Yolanda Curry, to work outa game plan.“I wasn't expecting it at all!” Curry said. "He told me he had a great idea and wanted to share it with me. I could tell he was really excited.Nelson, in association with his high school, set up the Joshua Nelson Leaders In Action Scholarship fund. Each year, $1,000 will be awarded to a senior. The money will come from donations, of which there have been $16,000 so far — for a total of $17,435 at last count, according to the school. With the money already in the fund, there's enough to give out a scholarship each year for over a decade. The first scholarship was awarded on June 1 to Darrell Montalvo-Luna. As the first recipient, his scholarship was $2,000.“Joshua has the heart of a servant leader. He leads by example and he's genuinely excited when good things happen for other people," Curry said. "He's an encouragement — he's good at building others up and does what he can to help encourage and motivate those around.4. What did Nelson's initial donation come from?A. His scholarship.B. His savings.C. His pocket money.D. His wages.5. What does the underlined phrase "having an open hand" in paragraph 2 mean?A. Ambitious.B. Courageous.C. Generous.D. Cautious.6. How did Curry feel when hearing Nelson's idea?A. Shocked.B. Confused.C. Excited.D. Delighted.7. What can be inferred about the Joshua Nelson Leaders In Action Scholarship fund?A. It never supports high school students.B. It was set up more than ten years ago.C. It was founded by Nelson and Curry.D. It is going very smoothly.COne rainy afternoon, I was on a crosstown bus when ayoung woman jumped on. She had a child with her who must have been about 3 or 4 years old.The bus was full, bumpy, and it soon got noisy as her kid began crying because he couldn’t sit next to his mother. There were a couple of open seats, but they weren’t together. She wasflusteredand looked embarrassed.Then another woman, a little older, stood up and moved so that the mother and child could sit together. The mom smiled as a thank-you. And then three words came out of the older woman’s mouth that elevated the entire energy of that bus ride: “I’ve been there”.Simple, undramatic and honest. In that moment, it seemed to unite people. Why? Because almost all experiences are shared human experiences. We forget that, as we forge (前进) through life, focused onour own troubles and needs—which are actually less unique than we think. How can these three words create more connection in your life? Ask yourself: “Where am I holding back?One thing I know for sure is this: Healing others helps heal yourself. I noticed this recently with my friend, Tracy, who took a new friend who had suffered a miscarriage under her wing. Tracy had three of them before having her daughter two years ago. Our intellect needs a doctor to explain the medical side of things, yes. But our souls need human connection to help us along. No one can do that better than someone who has been exactly where you are.Can the essence of these three words help you make a small difference right now? It can be as simple as volunteering your seat, sharing some helpful advice or even lightening the mood with a joke when you notice thatsomeone’s uncomfortable—because we’re all in this together.8. The underlined word “flustered” in the second paragraph is closest in meaning to _______.A. angryB. anxiousC.scaredD. upset9. What does the woman mean by saying “ I’ve been there”in the third paragraph?A. The woman was on the bus and saw what had happened to the boy.B. The woman got to her destination and was ready to get off the bus.C. The woman once had the similar experience with that mother.D. The woman took the exact seat that the boy was on just now.10. Which of the following statements is TRUE according to the passage?A. Everyone has his or her own unique problem that is difficult to solve.B. Doctors can help us get through when we have mental or physical problems.C. The author’s friend Tracy felt better after she was comforted by her new friend.D. One can indeed make a difference to those in need of help by doing simple things.11. The passage isintended to _______.A. show a harmonious world by telling some touching storiesB. praise those who are willing to help others in emergenciesC. appeal to readers to give timely help to those in needD. illustrate some ways of helping others in detailDMost teenagers are still trying to find their passion and purposes in life. However, not Gitanjali Rao. The 15-year-old girl has been coming up with innovative solutions to worldwide problems since she was ten. It is, therefore, not surprising that the teenager has won the honor of “America's Top Young Scientist”.In the third grade, Rao was inspired to build a device after witnessing the shocking story unfold in Flint, Michigan, where cost-cutting measures led to the use of a polluted river as the city's primary water supply and incredibly high levels of lead made their way into people's drinking water.After two months' research, Rao designed a small and portable device that used sensors to instantly detect lead in water. Called Tethys, after the Greek Goddess(女神) of freshwater, it attaches to a cellphone and informs the residents via an app if their drinking water contains lead. The design earned her the 3M Young Scientist Challenge in 2017. She is currently working with scientists and medical professionals to test Tethys' potential and hopes the device will be ready for commercial use by 2022.Later, Rao took on another social issue-drug addiction. Her app, called Epione, which won the Health Pillar Prize at the TCS Ignite Innovation Student Challenge in May 2019, is designed to catch drug addiction in young adults before it's too late.More recently, the teenager has developed an app named Kindly, which usesartificial intelligence technology to detect possible signs of cyberbullying(网上欺凌). When users type in a word or phrase, Kindly is able to pick it up if it's bullying, and then it gives the option to edit it or send it the way it is. It gives them the chance to rethink what they are saying so that they know what to do next time.All kinds of awesome, Gitanjali Rao has been selected from 5,000 equally impressive nominees(被提名人) for TIME Magazine's first-ever “Kid of the Year”.12. What gave Rao the idea of inventing the device Tethys?A. The incident of lead pollution.B. The issue with drug addiction.C. The shortage of water supplies.D. The high cost of purifying water.13. What is Rao expecting of Tethys?A. It'll remove metal from water.B. It'll make it to market soon.C. It'll win her a higher prize.D. It'll be fitted to cellphones.14. What will Kindly allow users to do?A. Receive pre-warning signals of threat.B. Input words into a computer automatically.C. Choose from secure social networking sites.D. Weigh their words before posting them online.15. Which of the following can best describe Gitanjali Rao as a young scientist?A. Ambitious and humble.B. Optimistic and adventurous.C. Talkative and outstanding.D. Creative and productive.第二节(共5小题;每小题2分,满分10分)阅读下面短文,从短文后的选项中选出可以填入空白处的最佳选项。

【考点定位】本题主要是考查结构性质位置关系【名师点晴】解答的关键是确定元素在周期表中的位置,根据同主族元素性质的相似性与递变性解答,注意掌握利用原子序数确定元素在元素周期表位置的方法,即。

由原子序数确定元素位置的规律:只要记住了稀有气体元素的原子序数(He—2、Ne—10、Ar—18、Kr—36、Xe—54、Rn—86),就可由主族元素的原子序数推出主族元素的位置。

(1)若比相应的稀有气体元素多1或2,则应处在下周期的第ⅠA族或第ⅡA族,如88号元素:88-86=2,则应在第七周期第ⅡA族;(2)若比相应的稀有气体元素少1~5时,则应处在同周期的第ⅦA族~第ⅢA族,如84号元素应在第六周期第ⅥA族;(3)若预测新元素,可与未发现的稀有气体元素(118号)比较,按上述方法推测知:114号元素应为第七周期第ⅣA族。

10.下列叙述正确的是A. 乙醇俗名酒精,不能使酸性高锰酸钾溶液退色B. 油脂在酸性或碱性条件下水解都可得到甘油和高级脂肪酸C. 石油裂化的目的是提高轻质燃料油的质量和产量D. 煤中含有的苯、甲苯、二甲苯等有机物,可通过煤的干馏来获得【答案】C【解析】【详解】A.乙醇俗名酒精,因为乙醇有羟基,能被酸性高锰酸钾溶液氧化,所以乙醇能使酸性高锰酸钾溶液褪色,故A错误;B.油脂在酸性条件下水解得到甘油和高级脂肪酸,油脂在碱性条件下水解都可得到甘油和高级脂肪酸盐,故B错误;C.石油裂化的目的为了提高轻质液体燃料(汽油,煤油,柴油等)的产量,特别是提高汽油的产量,故C正确;D.煤的组成以有机质为主体,构成有机高分子的主要是碳、氢、氧、氮等元素,煤不含苯和二甲苯等,故D错误。

故选C。

11.下列有关说法正确的是A. 蛋白质是由C、H、O、N四种元素组成的物质B. 硝基乙烷(CH3CH2NO2) 与甘氨酸(氨基乙酸)互为同分异构体C. 石油裂解和油脂皂化都是由高分子化合物生成小分子物质的过程D. 合成高聚物的单体是【答案】B【解析】分析:A.根据组成蛋白质的元素分析判断;B.分子式相同结构不同的化合物互为同分异构体;C.根据裂解的含义以及油脂不是高分子化合物分析;D.根据高聚物是加聚产物判断其单体。

详解:A. 蛋白质是由C、H、O、N、S、P等元素组成的物质,A错误;B. 硝基乙烷(CH3CH2NO2)与甘氨酸(NH2CH2COOH)的分子式相同,结构不同,互为同分异构体,B正确;C. 石油裂解是采取比裂化更高的温度,使石油分馏产物中的长链烃断裂成乙烯、丙烯等短链烃的过程,另外油脂也不是高分子化合物,C错误;D. 高聚物属于加聚产物,其单体是乙烯和丙烯,D错误。
