2016-2017学年山西省晋中市平遥中学高二(下)期中英语试卷(J)

2016-2017学年山西省晋中市平遥中学高二(下)期中英语试卷(J)副标题一、阅读理解(本大题共12小题,共4.0分)ALand Art,sometimes referred to as Earth Art or Earthworks,is a form of art which involves using physical landscapes to create art,taking art out of the museum and into the outside world.Modern Land Art movement really got going in the 1960s when American artists began creating Land Art on a large scale.Today,works of modern Land Art can be seen all over the world,sometimes right alongside much older pieces of Land Art created by people who lived thousands of years ago.Land Art,which is not necessarily unchangeable,can take a number of forms.For examples,in 1970Robert Smithson created the Spiral Jetty(螺旋状防波堤),made of a collection of stones and mud,in the Great Salt Lake.The American artist made a large jetty n a spiral shape which sticks out into the waters of the lake.Reshaping the landscape is a common characteristic of Land Art,which can be created by moving parts around.People can also add things to the environment to create Land Art,like salt,which is added to the Spiral Jetty.It is possible to use plants.In all cases,Land Art is immovable.Land Art is designed to gradually form,change,and eventually decay(衰落).That's one of the biggest differences between Land Art and most of the art one sees in the museums.Some works of art can exist only for a few hours or days.Others are exposed to rain and wind so that they develop and decay over time,which is part of the attractiveness in the eyes of the artists.1.What do we know about Robert Smithson?______A. He is a great creative artist.B. He lives near the Great Salt Lake.C. He made the most famous Land Art.D.

The workers in Finland are paid by the hour.B. The bosses in Finland are too busy to check the working hours of their employees.C. The workers are always honest with their working hours.D. The workers and their bosses will make an agreement in advance about the pay.7.It can be concluded that ______ .A. Finnish people are not smart enough in daily lifeB. Finland has been a good place for cheatsC. the Finnish society is of very high moral levelD. all the Finns are rich.【答案】【小题1】A 【小题2】B 【小题3】B 【小题4】C【解析】4.A.细节理解题.根据文章You can go anywhere in one,tell the driver to drop you at any place,say that you have some business to attend to,and then walk off without paying your fare可知在芬兰坐出租车,乘客是不会出租车司机被拒绝的无论他想去哪里;故选A.5.B.细节理解题.根据第三段Hotel guests have their meals free,so they naturally go to the free dining rooms to have their meals可知芬兰的大酒店提供食物为任何人;故选B.6.B.推理判断题.根据文章From then on they just say how many hours they have worked and they will be paid accordin gly可知不是芬兰的老板太忙没有时间检查工人的工作时间,而是两者相互信任;故选B.7.C.细节理解题.根据最后一段As the Finns always act on good faith in everything they do,living in such a society has turned everyone into a real"gentleman"可知芬兰社会具有很高的道德水平;故选C.文章描述了芬兰社会中一些在我们看来的奇怪的现象,从反面解释了芬兰社会很高的道德标准.考察学生的细节理解和推理判断能力,做细节理解题时一定要找到文章中的原句,和题干进行比较,再做出正确的选择.在做推理判断题不要以个人的主观想象代替文章的事实,要根据文章事实进行合乎逻辑的推理判断.CIt was a dark,wet November morning.It seemed like it would take a million years to get to summer again.I thought bears have got it right----what a perfect idea to sleep through the worst part of the year and wake up when spring comes!"Want some words of affirmation(肯定)?"a coworker,seeing my mood,kindly suggested."You don't think they would cheer you up?""Today?No."I shook my head."I used to think so too,"he said,"until I realized the effect my words had on a certain person.Well,it was someone I knew pretty well.I have to say I reated him rather badly.""You?But you are always so positive!How did you treat him badly?""I told him I did not like anything about him,really.I told him I did not even like his name.In fact,it wasn't only what I said.I also did pretty bad things to him.When he was hungry,I did not give him the chance to eat proper food.When he felt like doing something fun,I said to him that he was being childish and having fun was not productive (有成果的).And worst of all,when he was sick and needed care,I did not care.I told him to get up and get to work.And when he did,I never told him he did good work.You could say I was ashamed of him,"he said."I wanted to get rid of him because he just wasn't good enough for me---but couldn't.""But that was heartless!"He nodded."Then one day it all changed.I stood there in front of the bathroom mirror one morning.I saw the dark circles under his eyes,I saw the excess (过量的)weight.I saw the hair that needed cutting.And I saw the eyes that once had looked at the world eagerly.Now they were so sad and tired.And there and then I realized he deserved better.So I told the man I had disliked for so many years that he was a good person after all."My jaw (下巴)dropped.I looked at him---full of positive energy,in good shape,always ready to encourage others."Wow…"He winked (眨眼)at me."So how about having a little positive conversation with the bathroom mirror?The person in there has the greatest effect on you!"8.The first paragraph implies that ______ .A. the author felt frustrated that morningB. the weather in November was the worst in a yearC. the author didn't enjoy his work environmentD. the author always felt bad in winter9.The author's coworker used to be a person who ______ .A. was very proud of himselfB. treated people differentlyC. worked hard to keep fitD. criticized himself a lot10.Which paragraph gives a clue about who the person that a author's coworker treated badlywas?______A.

Be confident in the face of difficulty.C. Be positive about himself.D. Be kind to those who make mistakes.【答案】【小题1】A 【小题2】D 【小题3】B 【小题4】C【解析】8-11 ADBC8.A 推理判断题,根据It seemed like it would take a million years to get to summer again.似乎它需要一百万年的时间才到夏天.这里用到了一个虚拟语气,冬天代表着寒冷,也说明作者的心情不好.故选A.9.D细节理解题,根据第6段的内容"I told him I did not like..""I told him I did not even like""Ialso did pretty bad things""I did not give him the chance"从使用的否定以及like词来看,作者是带有批判性,而且是有很多的看法,所以答案是选D criticized himself a lot 对他批评很多.故选D.10.B细节理解题,根据第8段的描述"I stood there in front of the bathroom mirror one morning.有一天我站在卧室的镜子前"说明以下的内容是对着镜子说话的,也就是对他自己说话.故选B.11.C细节理解题,根据"I looked at him---full of positive energy,"和"So how about having a little positive conversation with the bathroom mirror"两句都出现了positive energy,说明作者会积极地面对.故选C.这是一篇人物故事类阅读.主要讲述了作者通过和同事的对话,明白了需要振作自己.本文是一个人物故事类阅读理解.题目涉及多道细节理解题,做题时结合原文和题目有针对性的找出相关语句进行仔细分析,结合选项选出正确答案.推理判断题也是要在抓住关键句子的基础上合理的分析才能得出正确答案,不要以个人的主观想象代替文章的事实,要联系上下文根据文章事实进行合乎逻辑的推理判断,切忌胡乱猜测,一定要做到有理有据.DEdmonton's Downtown Park is transformed into one huge stage for five days where artists are able to share their talents,and where people are able to celebrate and enjoythemselves.Since its beginning in 1980,the

food,reusable dishes are given a $2 plate fee,but that is returned when the plate is brought back.The festival has completely sold out of tickets,and in record time.But with big names such as Van Morrison and Jakob Dylan,it's easy to see how that was going tohappen.There is no parking area during the festival,so using the Park & Ride system or Edmonton Transit is highly recommended.A bike lock-up area is provided and will be available Thursday until Sunday one hour before the gates open until 45 minutes after the gates close.The Edmonton Folk Music Festival begins on Wednesday,Aug.4

cultures of the East and the West really distinguish each other a lot.(16)______The origin of the eastern cultures is mainly from two countries:hina and India.Both of the two cultures are fostered by rivers-the Yellow River in China and the Hindu River in India.(17)______ Then in Tang Dynasty of China,the Chinese culture gradually went overseas to Japan,mixed into the Japanese society and shaped the Japanese culture nowadays.Though a bit different from the Chinese one,it belongs to the same system.When the two mother rivers gave birth to the Eastern culture,another famous culture was brought up on the Mesopotamian Plain-the Mesopotamian Civilization.This civilization later on developed into the cultures of Ancient Greece and Ancient Rome.(18)______ Like the Chinese culture,the European one also crossed waters.When the British settled down in America,their culture went with them over the Atlantic Ocean.So the American culture doesn't distinguish from the European one a lot.(19)______ ake the language system for example.In the East,most languages belong to the pictographic language while the Western languages are mostly based on the Latin system.Other causes like human race difference counts as well.But what's more,due to the far distance and the steep areas between the East and West,the two cultures seldom communicate until recent centuries.So they grew up totally in their own ways with almost no interference (干扰)from the other.The differences are everywhere.(20)______ But different cultures make the world of 21st century more colorful.The cultural gap should not be the obstacle (障碍)to the civilization of human being.It ought to be the motivation of our going farther.A.Let us work together to keep a variety of culture.B.And these two are well-known as the base of the European culture.C.One important thing is to learn about other cultures.D.They helped the two cultures develop for centuries and form their own styles.E.They are obvious and affect people's ways of thinking and their views of the world.F.At the same time,some other differences add to the cultural differences.G.This is because the culture systems are two separate systems on the whole.12.

Modern Land Art movement really got going in the 1960s when American artists began creating Land Art on a large scale。
Today,works of modern Land Art can be seen all over the world, sometimes right alongside much older pieces of Land Art created by people who lived thousands of years ago。
Land Art, which is not necessarily unchangeable,can take a number of forms. For examples,in 1970 Robert Smithson created the Spiral Jetty (螺旋状防波堤),made of a collection of stones and mud,in the Great Salt Lake. The American artist made a large jetty in a spiral shape which sticks out into the waters of the lake。
