This year’s slogan (标语) is “Breathe Easily, Sleep Well”. Its aim is to celebrate the benefits of good and healthy sleep.Sleep is like food for the brain. Enough sleep helps the body and brain grow and develop. According to the National Sleep Foundation in the US, adults need seven to nine hours of sleep every night. For students aged 10 to 17, a healthy amount is about eight to nine hours per night. But many students don’t get enough sleep because of ea rly school start time and heavy homework. About 80 percent of middle school students don’t get enough sleep, the China Youth and Children Research Center reported. For some students, they want to sleep early, but they keep worrying about their schoolwork a nd can’t fall asleep quickly. For others, they may even have insomnia which might keep them awake (醒着的)all night.These sleeping problems greatly affect people’s lives. Experts have shown that lack of sleep for teenagers leads to poor grades. Students without enough sleep cannot pay attention in class or do well in sports. Also, the lack of sleep may make them depressed (沮丧的).试卷第2页，共10页Luckily, with good sleeping habits, it is easier to fall asleep. Some of these good habits include avoiding drinks that make people excited late in the day, going to sleep at the same time each night, and sleeping in a comfortable place that is dark, quiet, and neither too warm nor too cold. 1、If Li Hong is 15years old, how much sleep does she need every night? A ．10-12 hours. B ．8-9 hours. C ．7 hours. D ．Less than 7 hours. 2、What might happen if teenagers don’t get enough sleep? A ．They might do well in sports.B ．Their bodies and brains might grow better.C ．They might feel depressed.D ．They might not be able to finish their schoolwork.3、The underlined word “insomnia” means “_______” in Chinese. A ．健忘症 B ．肥胖症 C ．多动症 D ．失眠症4、Which of the following are good sleeping habits? a. Sleeping in a bright place. b. Going to bed at the same time. c. Sleeping in a dark and quiet place. d. Drinking something that makes you excited. A ．a-b B ．a-c C ．b-c D ．b-dWhat is language for? Some people seem to think it's for practicing grammar rules and earning lists of words —the longer the list, the better. That's wrong ．Language is for the exchange （交流）of ideas and information ．It's meaningless knowing all about a language if you can't use it freely. Many students I have met know hundreds of grammar rules, but they can't speak correctly or fluently （流利地）．They are afraid of making mistakes ．One shouldn't be afraid of making mistakes when speaking a foreign language. Native speakers make mistakes and break rules, too ．Bernard saw once wrote, "Foreigners often speak English too correctly ．"But the mistakes that native speakers make are different from those that Chinese students make. They're English mistakes in the English language ．And if enough native speakers break a rule, it is no longer a rule. What used to be wrong becomes right ．People not only make history, theymake language．But a people can only make its own language．It can't make another people's language. So Chinese students of English should pay attention to grammar, but they shouldn't overdo（做过头）it. They should put communication first.5、Language is used to ________.A．express oneself B．practise grammar rulesC．talk with foreigners only D．learn lists of words 6、Generally, when an American or an Englishman speaks English, he ________. A．never makes mistakes B．often makes mistakes C．can't avoid making mistakes D．always makesmistakes7、"Foreigners often speak English too correctly．"This sentence means that ________. A．foreigners speak correct EnglishB．foreigners speak incorrect EnglishC．foreigners speak English according to the grammar rulesD．foreigners never make mistakes when they speak English8、When we speak a foreign language, we should ________.A．speak in Chinese wayB．speak by the rulesC．speak to native speakersD．not be afraid of making mistakesAre you thinking about what to do in your free time?

广东肇庆实验中学-高要新桥中学两校16-17学年高一下期末考试--政治(解析版)
①必须坚持公民在法律面前人人平等原则
②任何公民的合法权利都受到保护
③人格尊严是公民最基本的政治权利
④必须坚持权利与义务统一原则
A.①②B.②④C.③④D.①③
【答案】A
【解析】本题考查公民参与政治生活的基本原则。本题材料强调尊重每一个人的权利，表明任何公民的合法权利都受到法律保护，体现了坚持公民在法律面前一律平等的原则，①②正确且符合题意；选举权和被选举权是公民的基本的政治权利，③说法错误；④与材料主旨不符，应排除；故本题答案选A。
①人民民主的特点是具有广泛性和真实性
②民主具有鲜明的阶级性
③人民民主是全民的民主
④我国在尊重和保障人权方面取得的成就体现了人民民主的广泛性
A.①②B.①③C.③④D.①④
【答案】A
【解析】题目中，习近平主席曾指出，民主和人权是人类共同追求，同时必须尊重各国人民自主选择本国发展道路的权利，我国的人民民主具有广泛性和真实性的特点，另外，民主具有鲜明的阶级性。故①②选项入选。③选项错误，不存在全民的民主。④选项表述错误，我国在尊重和保障人权方面取得的成就体现了人民民主的真实性。选A。
点睛：易错点---我国人民民主具有全民性的特点
该观点错误。我国是人民民主专政的国家，其本质是人民当家作主，我国人民民主具有广泛性，但并不意味着我国民主具有全民性。民主作为一种国家制度，具有鲜明的阶级性，民主总是属于统治阶级的。世界上从来不存在抽象的、超阶级的民主。我国的人民民主专政对最广大人民实行民主，对极少数敌人实行专政。是民主与专政的统一。
点睛：全面理解人民民主专政的本质是人民当家作主

AMr. Lee was in bed and was trying to go to sleep when he heard the bell ring. He turned on the light and looked at his clock. It was twelve o'clock. "Who can it be at this time of night?" He thought. He decided to go and find out. So he got off bed, put on his dressing gown (浴袍) and went to the door. When he opened the door, there was nobody there. "That is very strange." Then he went back to his bedroom, took off his dressing gown, got back into bed, turned off the light and tried to go to sleep. A few minutes later he heard the bell again. Mr. Lee jumped out of bed very quickly and rushed to the door. He opened it, but again he found no one there. He closed the door and tried not to feel angry. Then he saw a piece of paper on the floor. He picked it up. There were some words on it : "It is now after midnight(午夜), so it is April Fools’ Day. April fool to you!""Oh, it was the English boy next door!" Mr. Lee exclaimed (惊叫) and almost smiled. He went back to bed and fell asleep at once. The bell did not ring again.1. When did Mr. Lee go to bed?A. before twelve o'clockB. after twelve o'clockC. when the bell rangD. when he saw the boy2. Why did he rush to the door when he heard the bell ring the second time?A.

Some people seem to think it's for practicing grammar rules and earning lists of words—the longer the list, the better. That's wrong．Language is for the exchange（交流）ofideas and information．It's meaningless knowing all about a language if you can't use it freely. Many students I have met know hundreds of grammar rules, but they can't speak correctly or fluently（流利地）．They are afraid of making mistakes．One shouldn't be afraid of making mistakes when speaking a foreign language. Native speakers make mistakes and break rules, too．Bernard saw once wrote, "Foreigners often speak English too correctly．"But the mistakes that native speakers make are different from those that Chinese students make. They're English mistakes in the English language．And if enough native speakers break a rule, it is no longer a rule. What used to be wrong becomes right．People not only make history, they make language．But a people can only make its own language．It can't make another people's language. So Chinese students of English should pay attention to grammar, but they shouldn't overdo（做过头）it. They should put communication first. 8．Language is used to ________.A．express oneself B．practise grammar rulesB．talk with foreigners only D．learn lists of words9．Generally, when an American or an Englishman speaks English, he ________.A．never makes mistakes B．often makes mistakesC．can't avoid making mistakes D．always makes mistakes10．"Foreigners often speak English too correctly．"This sentence means that ________.

This year’s slogan (标语) is “Breathe Easily, Sleep Well”. Its aim is to celebrate the benefits of good and healthy sleep.Sleep is like food for the brain. Enough sleep helps the body and brain grow and develop. According to the National Sleep Foundation in the US, adults need seven to nine hours of sleep everynight. For students aged 10 to 17, a healthy amount is about eight to nine hours per night.But many students don’t get enough sleep because of early school start time and heavy homework. Ab out 80 percent of middle school students don’t get enough sleep, the China Youth and Children Research Center reported. For some students, they want to sleep early, but they keep worrying about their schoolwork and can’t fall asleep quickly. For others, th ey may even have insomnia which might keep them awake (醒着的)all night.These sleeping problems greatly affect people’s lives. Experts have shown that lack of sleep for teenagers leads to poor grades. Students without enough sleep cannot pay attention in class or do well in sports. Also, the lack of sleep may make them depressed (沮丧的).Luckily, with good sleeping habits, it is easier to fall asleep. Some of these good habits include avoiding drinks that make people excited late in the day, going to sleep at the same time each night, and sleeping in a comfortable place that is dark, quiet, and neither too warm nor too cold.12. If Li Hong is 15years old, how much sleep does she need every night?A. 10-12 hours.B. 8-9 hours.C. 7 hours.D. Less than 7 hours.13. What might happen if teenager s don’t get enough sleep?A.

是固定短语其中to为介词，后跟动词的ing做宾语．他们在盼望着那时见到你．本题考查非谓语动词中的动名词，动名词是非限定动词的一种形式，由动词原形+ing构成．它既有动词的特征，又有名词的特征，故称．动名词．动名词具有名词的性质，因此在句中可以作主语、表语、宾语、定语等．本题是动名词在句中做介词的宾语．45.I have made great progresses in my spoken English．______．【答案】progresses 改为progress【解析】答案是：progresses 改为progress；本题考查不可数名词；progress是不可数名词"进步"，不能用复数；故progresses

cleaner．______．【答案】Hopeful改为Hopefully【解析】答案是：Hopeful改为Hopefully；本题考查词性；英语中常常把副词放在句首，并且有逗号与句子的其它部分分开，做评注性状语，修饰整个句子；故把Hopeful改为Hopefully．希望更多的人会参加这项活动使我们的地球更干净．句子改错要在理解句子结构的基础上从词语搭配、词性、单复数、时态、非谓语动词等方面进行综合考虑，分析可能存在的错误；47.I

D.【答案】A【解析】试题分析：做曲线运动的物体的速度的方向是沿着运动轨迹的切线的方向，合力指向运动轨迹弯曲的内侧．解：曲线运动的物体受到的合力应该指向运动轨迹弯曲的内侧，由此可以判断BCD错误，A正确；故选：A．3. 某草地浇花草的喷水装置如图，由喷水口向两旁水平喷出，若忽略空气阻力及水之间的相互作用，则下列说法正确的是A. 喷水速度一定，水在空中运动时间也一定B. 喷水速度一定，喷水口越高，水喷得越近C. 喷水口高度一定，喷水速度越大，水喷得越远D. 喷水口高度一定，喷水速度越大，水在空中运动时间越长【答案】C【解析】水从喷水口沿水平喷出后做平抛运动，根据h=gt2，得：，则知喷水口高度一定，水在空中运动时间一定，与喷水速度无关，故AD错误．喷水速度一定，喷水口越高，水在空中运动时间越长，由x=v0t 知，水喷得越远，故B错误．喷水口高度一定，水在空中运动时间一定，根据x=v0t得：喷水速度越大，水喷得越远，故C正确．故选C点睛：解决本题时要明确水的运动情况，掌握平抛运动的基本规律，知道平抛运动的时间由高度决定，水平位移由高度和初速度共同决定．4. 一圆盘可绕通过其中心且垂直于盘面的竖直轴转动，现在圆盘上放置一个木块，当圆盘匀速转动时，木块随圆盘一起运动（保持相对静止），如图所示，那么下列说法正确的是A. 木块受到重力、支持力、摩擦力、向心力的作用B. 木块受到重力、支持力、摩擦力的作用C. 木块受到的摩擦力，方向与木块的运动速度方向相反D. 逐渐增大圆盘转速，木块不会发生滑动【答案】B【解析】木块受到重力、支持力、摩擦力的作用，故A错误，B正确；木块受到的摩擦力提供向心力，方向始终是指向圆盘中心，故C错误；逐渐增大圆盘转速，所需要的向心力增大，当静摩擦力不足以提供向心力时，木块会发生滑动，木块不会发生滑动，故D错误；故选B.点睛：静摩擦力的方向与物体的相对运动趋势方向相反，本题中静摩擦力指向圆心，说明物体相对圆盘有向外滑动的趋势.5. 下列有关功率的说法，正确的是A. 做功越多，功率越大B. 由P = W/t 知P与t成反比C. 功率越大，做功越快D. 完成相同的功，所花时间越长，则功率越大【答案】C【解析】做功多，功率不一定大，还要看时间，故A错误；由知当功不变时，P与t成反比，故B错误；功率是描述物体做功快慢的物理量，功率越大，做功越快，故C正确；由知，完成相同的功，所花时间越长，则功率越小，故D错误．故选C.6. 在下列实例中(不计空气阻力)机械能守恒的是A. 物体以一定初速度冲上光滑斜面B. 物体沿斜面匀速下滑C. 拉着一个物体沿着光滑的斜面匀速上升D. 物体做平抛运动【答案】AD【解析】物体以一定初速度冲上光滑斜面时只有重力做功，故机械能守恒；故A正确；物体沿斜面匀速下滑时，动能不变，重力势能减小，故机械能不守恒；故B错误；拉着一个物体沿着光滑的斜面匀速上升时，动能不变，重力势能增大，故机械能不守恒，故C错误；物体做平抛运动时，只有重力做功，故机械能守恒，故D正确．故选AD．点睛：本题考查了机械能是否守恒的判断，关键要掌握机械能守恒的条件，判断做功情况；同时也可以分析动能和重力势能的变化情况，从而明确机械能的改变．7. 如图所示，A、B两颗人造地球卫星绕地球做匀速圆周运动，下列说法正确的是A. 线速度大小关系：v A＞v BB. 线速度大小关系：v A＜v BC. 周期关系：T A＜T BD. 周期关系：T A＞T B【答案】AC【解析】试题分析：根据人造地球卫星的万有引力等于向心力，列式求出线速度、周期与轨道半径的表达式，再进行比较即可．解：设卫星的质量为m、轨道半径为r、地球的质量为M，根据万有引力提供向心力，得：G=m=m r可得：v=，T=2π可知，卫星的轨道半径越大，线速度越小，周期越大，所以，线速度大小关系为：v A＞v B．周期关系为：T A ＜T B．故AC正确，BD错误．故选：AC8. 如图甲所示，质量m=2kg的物体以100J的初动能在粗糙的水平地面上滑行，其动能E k随位移s变化的关系图象如图乙所示，则下列判断中正确的是A. 物体运动的总位移大小为10mB. 物体运动的加速度大小为10m/s2C. 物体运动的初速度大小为10m/sD. 物体所受的摩擦力大小为10N【答案】ACD【解析】试题分析：根据图象得出初动能和位移的大小，结合动能定理求出物体所受的摩擦力，根据牛顿第二定律求出物体的加速度．解：AD、由图象可知，物体运动的总位移为10m，根据动能定理得，﹣fx=0﹣E k0，解得f===10N，故AD正确；B、根据牛顿第二定律得，物体运动的加速度大小a==5m/s2，故B错误；C、根据E K0=mv02得，v0===10m/s，故C正确．故选：ACD．二、非选择题，全部为必考题。

He turned on the light and looked at his clock. It was twelve o'clock. "Who can it be at this time of night?" He thought. He decided to go and find out. So he got off bed, put on his dressing gown (浴袍) and went to the door. When he opened the door, there was nobody there. "That is very strange." Then he went back to his bedroom, took off his dressing gown, got back into bed, turned off the light and tried to go to sleep. A few minutes later he heard the bell again. Mr. Lee jumped out of bed very quickly and rushed to the door. He opened it, but again he found no one there. He closed the door and tried not to feel angry. Then he saw a piece of paper on the floor. He picked it up. There were some words on it : "It is now after midnight(午夜), so it is April Fools’ Day. April fool to you!""Oh, it was the English boy next door!" Mr. Lee exclaimed (惊叫) and almost smiled. He went back to bed and fell asleep at once. The bell did not ring again.1. When did Mr. Lee go to bed?A. before twelve o'clockB. after twelve o'clockC. when the bell rangD. when he saw the boy2. Why did he rush to the door when he heard the bell ring the second time?A. He wanted to open the door for the visitorB. He wanted to find out who the visitor was.C. He was afraid of the ringD. He was waiting for someone.3. From this passage, we learn that we can _______ on April Fools’ Day.A. say "Hello" to each otherB. dance and sing at nightC. play jokes on each otherD. send presents to children2.

Some people seem to think it's for practicing grammar rules and earning lists of words—the longer the list, the better. That's wrong．Language is for the exchange（交流）of ideas and information．It's meaningless knowing all about a language if you can't use it freely. Many students I have met know hundreds of grammar rules, but they can't speak correctly or fluently（流利地）．They are afraid of making mistakes．One shouldn't be afraid of making mistakes when speaking a foreign language.Native speakers make mistakes and break rules, too．Bernard saw once wrote, "Foreigners often speak English too correctly．"But the mistakes that native speakers make are different from those that Chinese students make. They're English mistakes in the English language．And if enough native speakers breaka rule, it is no longer a rule. What used to be wrong becomes right．Peoplenot only make history, they make language．But a people can only make its own language．It can't make another people's language. So Chinese students of English should pay attention to grammar, but they shouldn't overdo（做过头）it. They should put communication first.1. Language is used to ________.A. express oneselfB. practise grammar rulesC. talk with foreigners onlyD. learn lists of words2. Generally, when an American or an Englishman speaks English, he ________.A. never makes mistakesB. often makes mistakesC. can't avoid making mistakesD. always makes mistakes3. "Foreigners often speak English too correctly．"This sentence means that________.A. foreigners speak correct EnglishB. foreigners speak incorrect EnglishC. foreigners speak English according to the grammar rulesD. foreigners never make mistakes when they speak English4. When we speak a foreign language, we should ________.A. speak in Chinese wayB. speak by the rulesC. speak to native speakersD. not be afraid of making mistakes5. March 16th is World Sleep Day. This year’s slogan (标语) is “Breathe Easily, Sleep Well”. Its aim is t o celebrate the benefits of good and healthy sleep.Sleep is like food for the brain. Enough sleep helps the body and brain grow and develop. According to the National Sleep Foundation in the US, adults needseven to nine hours of sleep every night. For students aged 10 to 17, a healthy amount is about eight to nine hours per night.But many students don’t get enough sleep because of early school start time and heavy homework. About 80 percent of middle school students don’t get enough sleep, the China Youth and Children Research Center reported. For some students, they want to sleep early, but they keep worrying about their schoolwork and can’t fall asleep quickly. For others, they may even have insomnia which might keep them awake (醒着的)all night.Thes e sleeping problems greatly affect people’s lives. Experts have shown that lack of sleep for teenagers leads to poor grades. Students without enough sleep cannot pay attention in class or do well in sports. Also, the lack of sleep may make them depressed (沮丧的).Luckily, with good sleeping habits, it is easier to fall asleep. Some of these good habits include avoiding drinks that make people excited late in the day, going to sleep at the same time each night, and sleeping in a comfortable place that is dark, quiet, and neither too warm nor too cold.1. If Li Hong is 15years old, how much sleep does she need every night?A. 10-12 hours.B. 8-9 hours.C. 7 hours.D. Less than 7 hours.2. What might happen if teenagers don’t get enough sleep?A. They might do well in sports.B. Their bodies and brains might grow better.C. They might feel depressed.D. They might not be able to finish their schoolwork.3. The underlined word “insomnia” means “_______” in Chinese.A. 健忘症________B. 肥胖症C. 多动症________D. 失眠症4. Which of the following are good sleeping habits?a. Sleeping in a bright place.b. Going to bed at the same time.c. Sleeping in a dark and quiet place.d. Drinking something that makes you excited.A. a-bB. a-cC. b-cD. b-d二、完形填空6. Michael Greenberg is a very popular New Yorker.
