2017-2018学年高三九月月考题(注:本次月考不考听力,试题从21题开始)II、阅读理解:A“Snakes in the Gutter”can make an interesting game that can be played in school.For this, you need to make some of the children snakes.They have to stand in a line widely distanced from each other.To begin the game, you need to say, “Snakes in the Gutter.”After your announcement, the children try to get through the line of the snakes without getting caught.The kids who are caught by the snakes have to join the snakes' team.The one who keeps free till all the others are caught is the winner.If your school has a big enough playground, you can organize basketball, football and other such outdoor team games.Online games that help kids get skills in using the mouse and the keyboard are excellent games in modern times.To do well in image tracking games, kids need to decide quickly and correctly when clicking a moving thing.V ocabulary games are those of the best games to play in school.One of the exciting word games is building words from the disordered letters.Another game could be that of finding the spelling mistake in a given word.A game known as “Hangman”is played by giving a piece of information about the meaning of a word to the kids and telling them the number of letters in the words.There can be many such games to play in school.Remember to design games that are interesting as well as educative.Games in school serve as the best way to develop certain skills in children, and they are also full of fun and excitement.So, get going!21.In order to win the game “Snakes in the Gutter”,one should________.A.be caught as soon as possibleB.stand in a line to act snakesC.keep himself/herself free till the endD.say “Snakes in the Gutter”before the others22.By playing the image tracking games online children can improve their skills in________.A.finding out different picturesB.describing a moving thing correctlyC.communicating with each otherD.making a quick and right decision23.What can we learn according to the introduction of vocabulary games?A.They are usually played at home.B.They are used to improve kids' translation skill.C.They can help kids learn more words.D.They can help kids make sentences.24.The author's attitude towards games in school is________.A.unknown B.positiveC.uncertain D.negativeBMOST recently, my world has been shaken by the death of a teacher at my school.He was Dr.Allan Woolley and he was only 52.Suddenly he took his own life, which remains a mystery.That morning, everyone sensed that something wasn't right.During our lessons, an announcement was made that an assembly was scheduled for morning break, which was only done in emergencies.Once morning break came, the entire school gathered in the main hall.As our headmaster marched out to announce the “momentous news”,it felt like the air around us trembled.Many students broke down in tears, and the reaction afterward was intensely powerful and unifying.The headmaster said that students were allowed to miss lessons and have a free period to collect themselves if they found the news too distressing.Many students went outside and shared memories of Dr.Woolley to control themselves.Dr.Woolley taught me chemistry two years ago, but up until his death he still taught many of my close friends.Many of my friends were so shocked that they still couldn't believe the person that they had owed some homework to was now dead.It was heartwarming to spend time with teachers that morning and get to know more about them.Despite the time of sadness, I feel that every cloud has a silver lining.Although Dr.Woolley's death is something nobody wanted to see, we must move on.Notes:①assembly n.集会②schedule v t.安排③momentous adj.重大的④unifying adj.统一的⑤distressing adj.悲伤的25.What did the students feel at the news of their teacher's death?A.Unhappy. B.Shocked.C.Surprised. D.Silent.26.What does the underlined word “collect”in Paragraph 4 mean?A.Bring something together.B.Calm down.C.Increase in amount.D.Get and keep.27.Which of the following is NOT true according to the passage?A.The real cause of Dr.Woolley's death is known to us.B.Many students didn't prepare themselves for the bad news so that they felt very sad.C.It takes the whole school some time to recover from the depressing news.D.Dr.Woolley's death allows students to understand teachers better.28.It can be inferred from the underlined sentences in the last paragraph that________.A.Dr.Woolley's death made students sadB.there is still some comfort and hope in troubleC.Dr.Woolley's death disappointed students greatlyD.we should forget the fact to study betterCSome parents think that once their children are at school, they can relax themselves.But this is not the case at all.As research shows, parents have an even greater influence on their children's academic results than the school does.Most of a child's ability is formed from home.The mass of parents don't realise how they can help their children at home.Things are as simple as baking a cake.An example of helping young children with their maths is simply planning a birthday party.They have to decide how many people to invite, how many invitations they will need, how many prizes, balloons need to be bought, and so on.Children often find that real life experiences help them to do their maths more easily.Another way that parents can help their children with their maths is to give them pocket money.This not only teaches them about the value of money, but they may need to use basic maths to work out how long they will have to save to buy the special toy that they want.Reading to children at an early age can give them a head start when they start school.But parents should not stop reading to children when they do start going to school.They still like to be read to, and it can help to increase their sight vocabulary as well.Providing children with the right equipment can help with their education.Giving them a quiet place where they can work, read and do homework, with a good reading light and a comfortable chair and desk, is just some of these things.Parents can also help their children by providing them with some reference books, and any other relevant learning materials they might need.Evidently, parents do need to take an active role in the education of their children.If parents want their children to do well at school, they must be prepared to help educate their children at home.29.The passage is mainly talking about that________.A.education starts at homeB.parents can control their childrenC.ability affects a child's academic resultD.good equipment leads to good grades30.As for most parents,________.A.they don't think the research result is reasonableB.they have different opinions with expertsC.they are unaware of what to do for children at homeD.they are lazy in preparing the birthday party31.If you want to improve your child's maths ability, you can________.A.prepare his/her birthday party as big as possibleB.leave the things used for the party done by him/herC.purchase all the things needed by yourselfD.let your children count the cups and so onDQ:My neighbor's back garden is an overgrown jungle for a few months and I believe I've gotrats under my shed as a result.I have been troubled by such a bad scene for a long time.Can I make my neighbor manage her back garden?A:Firstly, you will need to contact a pest control company to deal with the rat problem, which could be a danger to you and your family.The pest control company will produce a report detailing the issue and give an opinion as to whether your neighbor's overgrown garden has caused the rats to run in all directions.If that is the case, then you should get in contact with your neighbor in an attempt to resolve the issue.You should discuss your concerns with all your heart with your neighbor and advise her of the situation and of the findings of the pest control company.You do not advise whether the house is rented out or perhaps your neighbor is elderly without the ability to deal with the problem personally.If your neighbor is uncooperative, then I would advise you undertake the following action.Get in contact with your local authority or the Department of Environment, Community and Local Government and report your concerns, particularly the pest issue immediately.You could also contact the HSE, more especially if children use the garden and are likely to come in contact with rat droppings etc, which can be dangerous to them.If the above is not successful, you should inform your lawyer and take advice.You should also document your conversations with your neighbor.If your house is for sale, ask your agent to prepare a report outlining the effect of the next door garden on value, but also outlining the effect on marketability and the negative impact on viewings.Notes:①uncooperative adj.不愿合作的,不愿配合的②authority n.权力,职权,官方,当局③marketability n.可销售性32.Which of the following is the BEST title for the passage?A.Can I Make My Neighbor Get Her Garden in Order?B.Should I Manage My Neighbor's Garden?C.Why Does My Neighbor Dislike Gardening?D.What on earth Does My Neighbor Do Every Day?33.What made the first person ask advice?A.The badly-organized plants in the garden.B.The overgrown garden caused rat problem in his shed.C.Being visited by the unexpected guests.D.His shed being blocked seriously.34.What does the pest control company perform?A.They help tidy up the neighbor's back garden.B.They only produce a report about rats.C.They perform a duty to deal with rats.D.They provide evidence as to pests for anyone.35.If the guess is TRUE, the asker________.A.should have an argument with his neighborB.should kill off the mice at firstC.should move away to a new placeD.should have a talk with her calmlyIII.

《诗经》原来是诗,不是‚经‛,这在咱们今天是很准确的。
但在封建社会里,诗三百篇却被尊为‚经‚,统治阶段拿它来做封建教化的工具。
从西周初期到春秋中叶,诗三百篇是一种配乐演唱的乐歌。
这些乐歌一方面用于祭祀、宴会和各种典礼,当作仪式的一部分或娱乐宾主的节目。
另一方面则用于政治、外交及其他社会生活,当作表情达意的工具,其作用和平常的语言差不多,当然它更加曲折动人。
例如周代有一种‚献诗陈志‛的做法,当一些人看到国君或者同僚做了什么好事或坏事,就做一首诗献给他们,达到颂美或者讽谏的目的。
还有人由于个人遭受冤屈或不幸,也往往通过诗来发泄和申诉。
应该说明,‚献诗陈志‛是要通过乐工的演唱来献给君上或同僚的,所以卿士‚献诗‛总和‚簪献曲‛或者‚瞍赋‛、‚矇诵‛并提。
在人民群众的生活里,诗歌也常用于表情达意,例如《诗经•邶风•新台》和《诗经•秦风•黄鸟》等,都是针对具体的现实问题而发的。
古代史传中还有一些不在三百篇之内的‚徒歌‛,例如《左传•宣公二年》记载宋国将军华元被郑国人提了去,后来逃回来,人民讥笑这位败军之将,做了一个歌儿对他唱。
这样的歌,从性质上说和‚献诗陈志‛没有什么分别。

AWith online courses, anyone can acquire knowledge in any field of interest for free. All you need is a computer, laptop or Smart phone, internet connection and a self-made schedule. You can even get a certificate on completing the course.21. Learners who choose Skillfeed need to ________.A. pay some fee if they want to continue after a monthB. equip themselves with the ability to use the computerC. have some knowledge of the design of websiteD. learn to upload their own high-quality video22. We can learn from the passage that Academic Earth ________.A. charges learners nothing for any courseB. has many lectures given by 8,500 lecturersC. provides college courses mainly to young menD. offers college courses at the learners’ convenience23. If you want to improve your skill of Japanese language, you can visit ________.A. https://B. https://C. https://D. https://BIt’s a common b elief that over time, pet owners start to look like their animals, and vice versa. Now comes the terrifying news that cats look up to their owners as role models and copy their behavior.Next time you reach for your fridge, think twice. If Kitty is watching, she is likely to overeat as well.What is your cat’s IQ?In a new study from the University of Messina, it turns out that indoor cats who live closely to their owners “mirror” the lives of their caregivers. They sleep at the same time, eat at the same t ime, and can even become more or less social depending on the behavior of their owners.“Cats are intelligent animals with a long memory, ”Jane Brunt, the executive director of the CA Talyst Council, told Discovery News. “They watch and learn from us, notin g the patterns of our actions, as evidenced by knowing where their food is kept and what time to expect to be fed, how to open the cupboard door that’s been improperly closed, and where their feeding and toileting areas are ”Because cats copy our habits, i f you spend a lot of time raiding( 搜刮)the fridge, your cat will return to its food bowl for that midnight snack, too. According to the study, this explains why “human and cat overweight rates often seem to match. ”So. if you felt guilty about leaving your precious kitty at home while you go to work, now you can feel even worse:y ou are making your cat fat!There’s no word if drinking green tea and making sure you go to Yoga will benefit your cat, but based on the study, it sounds like sticking to a healthy eating and sleeping schedule is best for both of you.There’s a lot we can learn from our cats in return. “When they sit on our laps softly purring with rhythmic breathing and half-closed eyes, the sense of peace and calm that comes over us is like a priva te 1esson in inner meditation. ”Brant said. Sure. But cats don’t have to sit in rush hour trafficfor an hour a day or worry about their in-laws. They’re probably pretty good at remaining calm.So, according to science, even though we assumed that cats were not close to us all these years, it turns out they are in fact learning from us and looking up to us. Scary, huh?24.According to the passage, which of the following is NOT true?A.Green tea and Yoga can benefit cats.B.Humans can learn from cats in some way.C.Cats are smart and have a long memory.D.Cats can copy humans’ schedule.25.What does the underlined word “this” in Paragraph 5 refer to?A.Humans’ keeping searching the fridge.B.Cats’ going to their owners for food.C.Cats’ copying humans’ habit of looking for food.D.Humans’ leaving cats home while working.26.What can we learn from our cats?A.To be able to copy. B.To remain calm.C.To stay proud D. To look up to friends27.The best title for the passage could be ________.A.Your Cat Can Bring You Pleasure B.You Are Copying Your CatC.You Can Make Your Cat Social D.Your Cat Is Copying Your HabitCAs computers become more popular in China, Chinese people are increasingly depending on computer keyboards to input Chinese characters. But if they use the computer too much, they may end up forgetting the exact strokes of each Chinese character when writing on paper. Experts suggest people, especially students, write by hand more.Do you write by hand more or type more? In Beijing, students start using a computer as early as primary school. And computer dependence is more widely spread among university students. Almost all their assignment and essays are typed on a computer.All the students interviewed say they usually use a computer. It’s faster and easier to correct if using a computer. And that’s why computers are being applied more and more often to modern education. But when people are taking stock in computers increasingly, problems appear.“When I’m writing with a pen, I find I often can’t remember how to write a character, though I feel I’m familiar with it.”“I’m not in the mood to write when faced with a pen and paper.”Many students don’t feel this is something to worry about. Now that it’s more convenient and efficient to write on a computer, why bother to handwrite?Many educators think differently. Shi Liwei, headmaster of a famous primary school in the capital said, “Chinese characters enjoy both practical and aesthetic value. But those characters typed with computer keyboards only maintain their practical value. All the artistic beauty of the characters is lost. And handwriting contains the writer’s emotion. Through one’s handwriting, people can get to know one’s thinking and personality. Beautiful writing will give people a b etter first impression of them.”To encourage students to handwrite more, many primary schools in Beijing have made writing classes compulsory(必修的)and in universities, some professors are asking students to turn in their homework and essays written by hand.28.The underlined expression “taking stock in” in paragraph 4 probably means.A. getting dependent onB. getting bored withC. becoming crazy aboutD. getting curious about29.The students interviewed prefer to write using a computer mainly because ___________.A. they can correct the mistakes they make quickly and convenientlyB. they are usually asked to e-mail their homework and essaysC. they find it not easy to remember how to write a characterD. computers have become a trend and fashion in China30.Which of the following statement is NOT true of the advantage of handwriting?A. Handwriting contains the writer’s emotions.B. Handwriting can impress people well and build one’s self-confidence.C. Chinese characters enjoy both practical and aesthetic value.D. The writer’s thinking and personality are shown in his or her handwriting31.Which of the following can best serve as the title of the passage?A. The Importance of Handwriting and Typing.B. Writing by Computer Will Replace Writing by Hand.C. To Type or to Handwrite.D. Practical and Aesthetic Value of Chinese Characters.DRuby’s RosesThe neighborhood kids nicknamed the strange old couple Crazy Jack and Ruby Rednose. Rumor was that they sat inside and drank whiskey all day. About the only words we ever heard from them were “Keep out of our rosebushes!” The rosebushes served as a fence between our house and theirs.Jack and Ruby had a son whom we nicknamed Crazy Jack Junior. He was due to come home from Vietnam. We heard he had been discharged because of a nervous breakdown. The day Crazy Jack Junior was scheduled to come home, we had a neighborhood softball game in our yard. Johnny was trying to catch a fly ball. He stripped over one of Ruby Rednose's rosebushes and fell on top of several more. Just at that moment, the Joneses' truck rolled into the driveway. Crazy Jack Junior sprang out and ran towards Johnny. “You little punk !” he screamed. “Look what you've done to our family's roses! You've always been trouble. I'm going to fetch my gun and shoot you!”Hearing this, my sisters and I ran into our house. Breathlessly, we told Mom what had happened. “Girls, I have told you not to play softball near those bushes. Come outside right now and help me fix them.”“Mom, we thought you didn't like the Joneses,” we protested. “They're mean to us. Besides, Crazy Jack Junior might shoot us.” Mom just glared at us. We followed her outside to help mend the rose fence. While Mom examined the damaged roses, Ruby slowly walked out. She looked sad. And it wasn't her nose that was red, it was her eyes.Ruby walked over to my mother. The two women stood looking at each other through the new gap in the rose fence. We girls held our breath, waiting to see who would shout first and what terrible things would be said.Suddenly my mother stepped forwards and hugged Ruby. “I'm glad your son came back home,” she said gently. “The girls will replace them if we can't fix them. In return for all the both er, they'll help you weed the roses this summer.” Ruby smiled at my mother through her tears. “I know we're particular about these roses ,” she said, “but they're very special to us. When my mother came from England, she brought one tiny part of her favori te rosebush. That was her reminder of home.”She paused a minute, then said sadly, “My mother had a magic touch with flowers. Over the years that one plant multiplied into all these bushes. Since she died, I've tried to keep them up, but I just don't have her magic touch.”Her voice was all choked up. “Mom died while Jack Junior was in Vietnam. He just found out about her death today. When he saw her rose bushes damaged, it was the last straw.” By now I felt really bad for the Jones—what a sorrowful homecoming! Soon both women were down on their knees talking and examining the damaged bushes together.My mother and Ruby worked together on the roses all summer long and many summers to follow. So did my sisters and I. A friends hip formed between the families that would includecountless birthdays, graduations and weddings—including Jack Junior's. The rose fence wasn't a fence any longer. My mother had turned it into a bridge.32.Which of the following statements is TRUE?A.Mr.and Mrs.Joneses were sociable and got on well with their neighbors.B.A couple of unfortunate events happened to the Jones' over the years.C.Crazy Jack Junior was seriously wounded in the Vietnamese war.D.Ruby and the author's mother glared at each other through the new gap.33.The underlined sentence in Paragraph 5 implies that ________.A.Ruby's mother had the greatest variety of flowersB.Ruby's mother was very good at raising flowersC.Ruby's mother devoted all her life to growing flowersD.Ruby's mother went to see and touch her flowers every day34.What's the right order of the events related to Ruby's roses?a.The roses grew into bushes and served as a fence.b.The author's mother turned the rose bushes into a bridge.c.Crazy Jack Junior threatened to kill Johnny.d.Ruby's mother brought one rose from England.e.Johnny fell while playing and damaged the roses.A.b, d, e, c, a B.d, e, a, c, b C.d, a, e, c, b D.b, d, a, e, c35.Which of the following best describes the author's mother?A.Merciful, generous and flexible.B.Strict, caring and considerate.C.Brave, aggressive and hard-working.D.Mean, tough, and skeptical.第二节阅读理解七选五(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最佳选项。
