辽宁省六校协作体2016-2017学年高一下学期期初英语试题学校:___________姓名:___________班级:___________考号:___________注意事项.1.答题前填写好自己的姓名、班级、考号等信息 2.请将答案正确填写在答题卡上第I 卷(选择题)一、阅读理解(题型注释)Many people go to school for an education. They learn languages, history, geography, physics, chemistry and mathematics. Others go to school to learn a skill so that they can make a living. School education is very important and useful. Yet no one can learn everything from school. A teacher ,no matter how much he knows, cannot teach his students everything they want to know. The teacher’s job is to show his students how to learn. He teaches them how to read and how to think. So much more is to be learned outside school by the students themselves.It is always more important to study by oneself than to memorize some facts or a formula(公式). It is actually quite easy to learn a certain fact in history or a formula in maths. But it is very difficult to use a formula in working out a maths problem. Great scientists, such as Einstein, Newton and Galileo didn’t get everything from school. But they were all so successful. They invented so many things for mankind. The reason for their success is that they worked hard all their lives, wasting not a single moment. They would ask many questions as they read and they did thousands of experiments.Above all, they knew how to use their brains.1、The subject which is not spoken of in the article is _____ A .maths B .history C .psychology D .physics试卷第2页,共10页2、The teacher’s job is to teach ___________. A .everything the students want to know B .the students everything that they know C .the students some facts of formulas D .the students how to learn3、Einstein, Newton and Galileo did so many things for mankind because_____. A .they learned a lot at school.B .they knew how to learn new things outside class by themselves.C .they were so useful.D .they went to college and learned form professors.4、From the passage we know that if we want to be successful , we should _______. A .only learn more at school B .needn’t go to school C .only learn science subjectsD .learn to learn at school and learn more outside schoolAre you looking for some new and exciting places to take your kids to? Try some of these places:Head to a natural history museum. This is where kids can discover the past from Dinosaur (恐龙) models to rock collections and pictures of stars in the sky. Also, ask what kind of workshops and educational programs are prepared for kids and any special events that are coming up.Go to a Youtheater. Look for one in your area offering plays for child and family visitors. Pre-show play shops are conducted by area artists and educators where kids can discover the secret about performing arts. Puppet (木偶) making and stage make-up are just a couple of the special offerings you might find.Visit art museums. They offer all kinds of activities to excite your kids' interest. Many offer workshops for making hand-made pieces, traveling exhibits, book signings( 签名) by children's favorite writers, and even musical performances and other arts.Try hands-on science. Visit one of the many hands-on science museums around the country. These science play-lands are great fun for kids and grown-ups alike. They'll keep your child mentally and physically active the whole day through while pushing buttons, experimenting,and building. When everyone is tired, enjoy a fun family science show, commonly found in these museums.5、If a child is interested in the universe, he probably will visit _________ .A.a Youtheater B.a natural history museumC.an art museum D.a hands-on science museum6、What can kids do at a Youtheater?A.Look at rock collections. B.See dinosaur models. C.Give performances. D.Watch puppet making.7、What does "hands-on science" mean in the last paragraph?A.Learning science by doing things. B.Science games designed by kids.C.A show of kids' science work. D.Reading sciencebooks.8、Where does this text probably come from?A.A science textbook. B.A tourist map.C.A museum guide. D.A news report.When we first gave our daughters (then 13 and 15 years old) cell phones for emergencies, we made them sign an agreement in which we strictly ruled where and when they could use their phones and even we could check their every text message. However, in less than a year, we lost control of the situation.There is a terrible reality that almost every teenager sends between 50 to 100 messages a day - some as many as 300, and 70% of teenagers admit hiding their online behavior from parents. According to a study, teenagers need as much sleep or more than they get as children - that's between 9 and 10 hours of sleep a night, but only 20% of them are getting it. When they don't get enough sleep, they perform poorly in school, feel very hungry, are more likely to have flu and are very emotional.Recently, we adopted a "check in at tuck in" (盖被子时交手机) rule at our house, an idea I learnt from a parenting expert. It is very simple. At bedtime, when we "tuck in" our children for the night, they must "check in" their phones. They will probably bargain like this:"But I use it for my alarm clock.""I'll wake you up."试卷第4页,共10页"My friends might need me.""If there is an emergency, they can call the fixed phone and I'll wake you up."A few weeks ago, when I drove my younger daughter to a friend's house for a sleepover, she handed me her phone. "I guess I should check this in now, since you won't be there to tuck me in tonight. I'll call you from Ellie's phone if I need you." 9、The first paragraph that the writer writes is to______. A .show the writer's family lifeB .lead to the topic of the passageC .advise to buy cell phones for childrenD .introduce the writer's two daughters10、The cell phones were bought for children in hope of_______. A .controlling their online behavior B .working hard through the Internet C .replacing alarm clocks with cell phones D .keeping in touch if something urgent happened11、Which of the following is NOT caused by sleeping less? A .Performing well in school. B .Feeling very hungry. C .Being easy to have flu. D .Being very emotional.12、Which is probably the best title for the passage? A .How to Take Control of Children B .How to Help Children Sleep Well at Night C .How to Get Children off Cell Phones at Night D .How to Assist Children with Cell PhonesJack Ma, the founder and executive chairman of e-commerce giant Alibaba Group, and US president-elect Donald Trump met at Trump Tower in New York City on Jan,9th 2017, with Trump calling it a "great meeting" and Ma saying the meeting was "very productive" "We had a great meeting, and a great, great entrepreneur (企业家), one of the best in the world, and he loves this country, and he loves China," Trump said. "Jack and I are going to do some great things."The two met with reporters briefly after the meeting, and said they discussed plans to create 1 million US jobs by allowing US small and medium-sized businesses to sell to China through Alibaba's platforms."We're focused on small business," Ma told reporters. And he had complimentary words for Trump: "I think the president-elect is very smart, he's very open-minded to listen. I told him my ideas about how to improve trade, especially to improve small business, cross-border trade." "We also think that the China and USA relationship should be strengthened — should be friendlier," Ma said. "The door is open for discussing the relationship and trade issues." The meeting comes in tensions between China and the incoming Trump administration(政府). Trump has repeatedly criticized China for its economic policies and accused the country of "stealing jobs away" from the US.Trump also has said he may raise tariffs(关税) on Chinese goods sold in the US. 13、When Jack Ma and Trump met at the beginning of this year, _________ A. Trump has taken office as a new president of USA.B. Jack Ma and Trump took a friendly attitude towards each other.C. they discussed plans to allow US businesses to sell to Asia.D.

如何看待“燕赵文化”燕赵区域以燕山、太行山、渤海、黄河为四面分界,主体为次生黄土的平原地带。
虽然这一区域具有“地边胡,数被寇”的特点,但燕赵文化仍属于华北平原上以汉族为主的旱地农耕文化。
燕文化与赵文化有着不同的来源和各自的特征,但又大体接近而趋同。
相对于其他周边区域而言,“慷慨悲歌”是燕赵文化的共同基调。
燕赵区域的文化特征就是“慷慨悲歌”,也只有“慷慨悲歌”才是燕赵区域的文化特色。
具有特征主线的区域文化是优越的文化。
在全国各个地域中,燕赵区域是极少数真正形成了文化特征的地域之一。
燕赵文化得以形成“慷慨悲歌”这一特征主线,为古今所共认,历代所称道,其内涵鲜明,无可否认。
这是燕赵区域的优越之处,值得骄傲。
中国古代“知己”、“知音”的价值观念,是“燕赵悲歌”的产生机制。
燕丹的精诚与荆轲的侠士志向契合在一起,就形成了“慷慨悲歌”。
慷慨悲歌是一个情结,是由经济文化的落后和政治地位的低下而导致的一个情结。
这个情结经过一种壮烈的撞击,发生逆转,出现升华,于是就化育成为慷慨悲歌的性格。
而这也正是北方历史文化发展的一个缩影。
“慷慨悲歌”的历史认同,有三次高潮。
荆轲刺秦王,与燕太子丹在易水告别,高渐离击筑,荆轲作歌,这是燕赵文化慷慨悲歌特征的第一次概括。
汉末曹魏时,曹操等人以邺都为活动中心,诗风雄峻古朴,慷慨悲凉,燕赵文化第二次被称作慷慨悲歌。
唐代,高适等人以气质自高,慷慨悲歌,临风怀古,燕赵文化第三次被人称为慷慨悲歌。
燕太子丹、荆轲的谋刺秦王,标志了燕地文化的形成和成熟。
从此以后燕文化就永久性地定格于此,成为燕赵文化所独有的固定不变的意象。

(9分.毎小题3分)宋词中的女性之美宋词中的女性,都是被作为客观审美对象来描写的,不管她们的身份如何,都是那么的千娇百媚,妖娆多姿。
她们简直就是美的化身,美的精灵,给人以美不胜收的感觉。
美女性美既是一种自然美,又是现实中崇高的美,它是作品经常涉及和表现的对象,而以诗歌来描写女性、歌咏女性之美,古已有之,早在《诗经》中就出现了描写女子的体态之美的作品,如手如柔夷,肤如凝脂,领如蝤蛴,齿如瓠犀,螓首蛾眉,巧笑倩兮,美目盼兮等,虽然写得比较简单,但却为后世所称道。
《诗经》以后的《楚辞》、汉乐府中均有一些多姿多彩的女性主人公,对美女的铺陈描写在诗歌中也得到了进一步的发展。
然而,女性之美在诗歌中并没有普遍出现。
魏晋以来,描写女性渐成诗坛风尚,特别是南朝出现的宫体诗,第一次将女性放到了诗歌的表现中心,这是诗歌创作中的一次重大折。
宫体诗对女性美的着力描写,其意义在于,开启了为女性写作的新风气,开辟了新的文学审美领域。
它不仅使女性美大规模地进入了文学的创作领域,而且从文学发展的角度来看,它对中晚唐五代出现的以香奁体为代表的艳情诗以及自南朝之宫体,扇北里之倡风的曲子词的创作都产生了自接的影响。
诗庄词媚,词为艳科,词与男女艳情有着与生俱来的密切关系,而在以柔情风月、思恋别怨为内容的宋词中经常浮动着女性的身影。
在女性的描写上,宋词既与宫体诗、花间词一脉相承,又比其更为丰富,这是因为词体更具有得人独厚的优势。
词之为体,要吵宜修,能言诗之所不能言,不能尽言诗之所能言。
词不同于诗,它是一种女性化的文学,并且具有一种女性化的美感。
与诗歌相比,词更适宜于表现女性的美。
旱在词的原生阶段的作品敦煌民间词中,就有对女性美的细致刻画,如:颜容二八小娘,满头珠翠影争光,百步唯闻兰麝香(《竹枝子》)等。

Surprised.【答案】【小题1】B 【小题2】D 【小题3】D 【小题4】A【解析】21-24 BDDA21 B 推理判断题.根据第五段中的My Spanish teacher said that speaking to others loudly instead of reading to ourselves will help us with our pronunciation.可推知,James用西班牙语大声数数是为了练习准确发音.故选B.22 D 推理判断题.根据第二段中的I can't focus on my study if you keep talking.可推知,Matt离开厨房是因为James大声数数,让Matt无法集中精力.故选D.23 D 推理判断题.根据文章中的Matt asked,expecting James to stare at the sign without understanding.及To Matt's surprise,James read the sign out loud.可推知,Matt原本认为James读不出那个西班牙语的招牌,结果James会读,所以Matt很吃惊.故选D.24 A 推理判断题.根据倒数第二段中的"Spanish is easy and fun to learn,"James replied,smiling with confidence.可推知,James听到Matt的表扬而感到很高兴.故选A.本文为记叙文.文章记叙了James通过大声朗读来学习西班牙语的故事.一、速读全文,了解大意知主题.阅读能力一般指阅读速度和理解能力两个方面.阅读速度是阅读最基本的能力.考生必须在十分有限的时间内运用略读、扫读、跳读等技巧快速阅读,搜寻关键词、主题句,捕捉时空、顺序、情节、人物、观点,并且理清文章脉络,把握语篇实质.二、看题干,带着问题读文章.首先要掌握问题的类型,客观信息题可以从文章中直接找到答案;而主观判断题考查的是对文章的感情基调等,这类题必须经过对作者的态度、意图以及对整篇文章进行深一层的推理等.其次,了解试题题干以及各个选项所包含的信息,然后有针对性地对文章进行扫读,对有关信息进行快速定位.此法加强了阅读的针对性,提高了做题的准确率.三、逻辑推理,做好深层理解题.在实际阅读中,有时作者并未把意图说出来,阅读者要根据字面意思,通过语篇逻辑关系,研究细节的暗示,推敲作者的态度,理解文章的寓义.要求读者对文字的表面信息进行分析、挖掘和逻辑推理,不能就事论事,以偏概全.推理题在提问中常用的词有:infer,imply,suggest,indicate等.四、猜词悟义,扫除阅读拦路虎.猜词是应用英语的重要能力.它不但需要准确无误地理解上下文,而且要有较大的泛读量,掌握或认识较多的课外词汇.我们要学会"顺藤摸瓜",通过构词,语法,定义,同位,对比,因果,常识,上下文等线索确定词义.BDo you know the differences between African and Asian elephants?African elephants have larger ears,and both male and female African elephants have tusks(象牙)while only maleAsian elephants have tusks.African elephants have very useful trunks!Since they live where it's always really hot,they get a trunk full of water and spray it on their backs.Then,they do the same thing with dust.The ends of their trunks work like little fingers.They use them to pick berries,grass,and other plants to eat.To drink,African elephants can suck up to two gallons of water in their trunks,then blow it into their mouths.If they sense danger,they use their trunks to make a loud warning sound.They even hug other elephants with their trunks.Do you know that the closest relative of elephants are manatees(海牛)?They can weigh up to 1,300pounds and they are good swimmers.If they're in really shallow water,they use their front flippers(鳍状肢)to walk while they eat sea plants and grasses.Because they are so slow and like warm,shallow water,manatees often get hurt by a part of the boat when the drivers don't see them.Manatees are sea mammals like whales and dolphins.They live in water,but they need to breathe air,so they often go to the surface of water.They can stay underwater for up to 15 minutes.5.From Paragraph 1we know that ______ .A. male African elephants have longer tusks than female oneB. African elephants have smaller ears than Asian elephantsC. female Asian elephants don't have tsksD. Asian elephants are larger than African elephants6.What is Paragraph 2 mainly about?______A. The way African elephants drink and eat.B. How African elephants use their trunks for protectionC. The shape of African elephants'trunks.D. The use of African elepants'trunks.7.Why do manatees often go to the surface of water?______A. Because they can stay underwater for only 5minutes.B. Because they want to watch out for danger.C. Because they need to breathe air.D. Because they want to look for food.【答案】【小题1】C 【小题2】D 【小题3】C【解析】25.C.细节理解题.根据第一段African elephants have larger ears,and both male and female African elephants have tusks(象牙)while only male Asian elephants have tusks可知雌性亚洲象没有象牙;故选C.26.D.细节理解.根据第二段They use them to pick berries,grass,and other plants to eat.To drink,African elephants can suck up to two gallons of water in their trunks,then blow it into their mouths可知第2段主要讲的是非洲象象牙的使用;故选D.27.C.细节理解题.根据文章Manatees are sea mammals like whales and dolphins.They live in water,but they need to breathe air,so they often go to the surface of water可知海牛经常去水的表面因为他们需要呼吸空气;故选C.本文属于说明文阅读,作者通过这篇文章主要向我们描述了非洲象的特点,象牙的作用和它的起源.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.CHiking,also walking for a long distance in the countryside is one of life's simple and cheap pleasures.But is it safe?Sports writer Mark Waters considers the risks.Imagine the following…One day,Ronald decided to take up hiking.The next Sunday,he got up early,threw a sandwich and a bottle of water into a bag and headed for Sai Kung Country Park.Before going,he quickly looked at a map and decided that he could easily walk from the bus stop at Park Tam Chung to the beach at Dai Long Wan.After walking for hours and hours under the hot sun,Ronald started to feel tired.He reached for his water but found that the bottle was empty.Then he smelt smoke and saw a fire.In a panic,he called 999.However,when he got through to the police,he couldn't tell them where he was because he didn't have a map…Think about it…Put yourself in Ronald's shoes.How could you stop this of thing happening to you?One way is to be know the following common types of danger.8.Getting lostFoggy weather is one reason why some walkers get lost.However,a more common one is not having enough knowledge of the hiking route.Always remember to bring a map and don't be too confident.Always choose a route that is right for you.9.Heat stroke(中暑)The summer in Hong Kong is very hot and wet.Many hikers forget this and walk for too long in the midday heat.They become hot and feel weak.Don't forget during exercise,it is necessary to drink 100 to 200 milliliters of water every 15 to 20 minutes.10.AccidentSome of Hong Kong's paths are very hazardous and it's not unknown for hikers tofall.Never walk alone and always bring a map and a mobile phone with you.11.Hill fireOn average,over 10,000 hill fires a year take place in Hong Kong,injuring more than 600 people.Never light fires in non-marked areas and,if you see a hill fire,reportit.Always stay calm and walk away from the fire into the wind.28.What can we learn about Ronald?______A.

It dated back to 1582.B. People enjoy this holiday.C. Its origin is related to a calendar.D. Pope Gregory XIII created this holiday.13.Which of the following is a good joke on April Fool's Day?______A. Skip a class when the teacher is out.B. Fill someone's closed umbrella with water.C. Give someone soap that turns his hands dirty.D.

store to buy some breads.After the man in the store packing the bread in a small bag for me,I began to walk home with∧bag in my hand.On the way I met my next-door neighbor,Miss Wang,that was walking her dog.We greeted with each other and begin to talk about the weather .As we were talking,his dog jumped up at the bag in my hand though the bread gave off a delicious smell.As a r esult,some of the bread fell to the ground or the dog began to enjoy it.Five minutes late,I was back at the store to buy bread again.详解:1.breads改为bread 考查名词.bread是不可数名词,没有复数形式.2.packing改为packed 考查动词时态.句中缺少谓语动词,而且文章叙述过去的事情,把packing改为过去式packed.3.加the 考查冠词.bag 为可数名词,并且是指前面提到过的bag,加定冠词the表示特指.4.that改为who 考查定语从句.分析句子结构可知这是一个定语从句,先行词neighbor 在从句中作主语,用关系代词who,that不可用于非限制性定语从句中.5.去掉with 考查词语用法.greet是及物动词,后面直接跟宾语,不需要介词with.6.begin改为began 考查动词时态.句中begin 和greeted 是并列谓语,全文用一般过去时.7.his改为her 考查代词.her指代前文中的my next-door neighbor,Miss Wang.8.though改为because/as/since 考查连词.前后两个分句之间是因果关系,用连词because/as/for/since.9.or改为and 考查连词.前后两个分句之间是并列关系而非选择关系,用连词and.10.late改为later 考查副词.later用于一段具体时间之后,表示从过去或将来算起的多长时间以后,但通常不指从现在算起的多久以后.。

Eudy and Tula,the two dogs guarding Middle Island,are now 8 years old They are almost ready to retire (退休). Local groups are trying to raise $ 25,000 needed to buy and train two new pups. 1、How many little penguins are living on the island now?A .Fewer than 10.B .About 200.C .About 800.D .More than 25,000. 2、Why did the little penguins almost completely disappear?
