牛津译林版高中英语必修1:单元综合检测(一)Ⅰ.阅读理解(共15小题;每小题2分,满分30分)AIn America,when the eighth­graders leave the middle school,they are often worried about moving to the high school.It is ahard time for them,but it can be an exciting one as well.To makeit easier,students need to get familiar with their school.Even though they've done this already in the middle school,it's still important to find where their classrooms are.Most schools take students to the high school for a visit at the end of their eighth grade year.And most schools also have a freshman (新生) speech for parents and students before the first year begins.Sometimes the main office will give away a map of the school.This can help students and parents find different places in the school.One way to know your high school more and make new friends is to join a club or play a sport.Schools often offer chances to join different clubs and sports.Fall activities begin in August before the first day of school.If you are not interested in sports,there are clubs for any interest,such as drama,dance,chess,photography,community service,etc.Students from different grades are allowed to join these clubs.By joining an activity,students can find new friendships,not to mention improving their chances in future college applications(申请).The school office will have a list of activities offered at the school and information on how to join them.What's more,to have a great start to a high school year,students can write down some of their worries,and ask for help from teachers and school workers.【语篇解读】本文是一篇说明文,为即将步入高中生活的学生们提供相关信息。

ATravelling to Europe to see its famous monuments like the Eiffel Tower in Paris and the Colosseum(古罗马竞技场)in Rome,is not exactly the ideal vacation for kids.Fortunately,Europe has more to offer than lots of old churches and ancient history.You can enjoy some fun with your kids in the sun at some of the famous beaches of the continent.Mykonos,GreeceThe closer you get to the equator,the longer the beach season is,and Greece is wonderful for that.You can enjoy beautiful green water,public chairs and lovely umbrellas at the beaches in Mykonos.Dubrovnik,CroatiaThere's nothing more attractive than the beautiful beaches bordering Dubrovnik,Croatia's most beautiful city.It's surrounded by stone walls like a castle.It almost makes you feel like you're suntanning(晒黑皮肤) at Hogwarts,where the hero Harry Potter of the story is trained!Sicily,ItalyRabbit Beach on the island of Sicily offers shallow and crystal clear waters,making it a perfect beach for families with young children.And if you want to add interest to your experience,try snorkeling(徒手潜水).Nice,FranceLined with palm trees and first-class hotels,the city of Nice,located on the French Riviera,offers a whole coastline of Mediterranean beaches.Because they're in the heart of the city,these beaches attract a large crowd.So if you're looking for something more private,you'll have to travel a few miles outside of the city center.Ribadeo,SpainAt low tide,Playa de las Catedrales in Ribadeo,Spain is the perfect beach to takein the natural wonders without urban amusements like restaurants,bars or huge crowds.It boasts beautiful wild flowers and unique rock formations making it truly a picture worthy.【语篇解读】文章介绍了几个欧洲著名的沙滩旅游景点。

高中语文单元综合检测(一) 语文版必修(时间:150分钟,分数:150分)第Ⅰ卷(阅读题,共70分)甲必考题一、现代文阅读(9分,每小题3分)阅读下面的文字,完成1~3题。

一切事物都有几种看法。

你说一件事物是美的或是丑的,这也只是一种看法。

换一种看法,你说它是真的或是假的;再换一种看法,你说它是善的或是恶的。

同是一件事物,看法有多种,所看出来的现象也就有多种。

实用的态度以善为最高目的,科学的态度以真为最高目的,美感的态度以美为最高目的。

在实用态度中,我们的注意力偏在事物对于人的利害,心理活动偏重意志;在科学的态度中,我们的注意力偏在事物间的互相关系,心理活动偏重抽象的思考;在美感的态度中,我们的注意力专在事物本身的形象,心理活动偏重直觉。

真善美都是人所定的价值,不是事物所本有的特质。

离开人的观点而言,事物都混然无别,善恶、真伪、美丑就漫无意义。

就“用”字的狭义说,美是最没有用处的。

科学家的目的虽只在辨别真伪,他所得的结果却可效用于人类社会。

美的事物如诗文、图画、雕刻、音乐等等都是寒不可以为衣,饥不可以为食的。

从实用的观点看,许多艺术家都是太不切实用的人物。

然则我们又何必来讲美呢?人性本来是多方的,需要也是多方的。

真善美三者俱备才可以算是完全的人。

人性中本有饮食欲,渴而无所饮,饥而无所食,固然是一种缺乏。

人性中本有求知欲而没有科学的活动,本有美的嗜好而没有美感的活动,也未始不是一种缺乏。

真和美的需要也是人生中的一种饥渴——精神上的饥渴。

疾病衰老的身体才没有口腹的饥渴。

同理,你遇到一个没有精神上的饥渴的人或民族,你可以断定他的心灵已到了疾病衰老的状态。

人所以异于其他动物的就是于饮食男女之外还有更高尚的企求,美就是其中之一。

是壶就可以贮茶,何必又求它形式、花样、颜色都要好看呢?吃饱了饭就可以睡觉,何必又呕心血去做诗、画画、奏乐呢?“生命”是与“活动”同义的,活动愈自由生命也就愈有意义。

人的实用的活动全是有所为而为,是受环境需要限制的,人的美感的活动全是无所为而为,是环境不需要他活动而他自己愿意去活动的。

【XZB2019TBYLYYB05001】单元综合检测(一)Unit 1 Getting along with others(时间:100分钟;满分:120分)Ⅰ.阅读理解(共10小题;每小题2.5分,满分25分)A(2019·安徽省淮北市第一中学高二下学期第一次月考)Living and dealing with kids can be a tough job these days, but living and dealing with parents can be even tougher.If I have learned anything in my 18 years, it is communication that is very important, both when you disagree and when you get along.With any relationship, you need to let others know how you are feeling.If you are not able to communicate, you drift apart.When you are mad at your parents, or anyone else, not talking to them doesn't solve anything.Communication begins with the concerns of another.It means that you can't just come home from school, go up to your room and ignore everyone.Even if you just say and see how their day was for five minutes, it is better than nothing.If you looked up the word “communication”in a dictionary, it would say “the exchange of ideas, the conveyance of information,correspondence (通信),means of communication: a letter or a message”.To maintain a good relationship, you must keep communication strong.Let people know how you feel, even if it's just by writing a note.When dealing with parents, you always have to make them feel good about how they are doing as a parent.If you are trying to make them see something as you see it, tell them that you'll listen to what they have to say, but ask them politely to listen to you.Yelling or walking away only makes the situation worse.This is an example: one night, Sophie went to a street party with her friends.She knew she had to be home by midnight after the fireworks, but she didn't feel she could just ask to go home.That would be rude.After all, they had been nice enough to take her along with them.Needless to say, she was late getting home.Her parents were mad at first, but when Sophie explained why she was late, they weren't as mad and let theincident go.Communication is the key factor here.If Sophie's parents had not been willing to listen, Sophie would have been in a lot of munication isn't a one­way deal: it goes both ways.Just remember: if you get into a situation like Sophie's, tell the other person how you feel-listening is the key factor to communication.1.What is the main idea of the second paragraph?A.The disagreement between generations.B.The importance of communication.C.The great importance of keeping silent.D.The necessity of making your feeling known.2.When parents and children are in communication, the key to a happy relationship is that .A.parents should listen to their childrenB.children should always obey their parentsC.parents and children should not yell or ignoreD.equality plays a part in family communication3.What can we learn from the passage?A.Walk away instead of yelling if communication fails.B.It is better to say “Hi”to others than say nothing.C.Talking is more important than listening in communication.D.You should feel good about yourself when communicating.BPeople seem to have a natural need for friends and with good reason.Friends increase your enjoyment of life and relieve feelings of loneliness.They even can help reduce stress and improve your health.Having good friends is especially helpful when you are going through any kind of hard time such as when you are experiencing anxiety,panic attacks,or depression.When you are with good friends you feel good about yourself,and you are glad to be with them.A friend is someone who●you like,respect,and trust,and who likes,respects and trusts you●doesn't always understand you,but accepts and likes you as you are,even asyou grow and change●allows you the space to change,grow,make decisions,and even make mistakes●listens to you and shares with you both the good times and the bad times●respects your need for secrets,so you can tell them anything●lets you freely express your feelings and emotions without judging,teasing,or criticizing you●accepts the limitations you have put on yourself and helps you to remove themA person once said,“Friendship is a continuing source of bonding(连接),releasing,and creating in yourself and with the other person.There is an emotional bond between the two people.”A good friend or supporter may or may not be the same age or the same sex as you,and may not have the same educational,cultural,or religious background,or share interests that are similar to yours.Friendships also have different depths.Some are closer to the heart and some more superficial,but they're all useful and good.4.Which of the following is NOT a function of a friend?A.He brings you some happiness.B.He helps you feel less lonely.C.He helps you get over the difficulties.D.He helps you cheat on the exam.5.The underlined word “superficial” means .A.deep B.hardC.shallow D.close6.Which is the best title for the passage?A.A Friend in Need Is A Friend IndeedB.What Kind of Person A Friend Should BeC.To Be A Good FriendD.How To Get on with Your FriendCThe media provides us with the observations and experiences from which we build up our personal understanding of the world and how it works.Much of our view ofreality is based on media messages.The media,to a great extent,gives us our sense of reality.Freedom of the media carries with it certain responsibilities of honesty,fairness,accuracy and accountability.The power of the media to create and destroy human values comes with great responsibility.The media is powerful in the political system,having greatinfluence on politics and on forming social change.The power isto decide who will communicate what to whom.Television cangreatly influence the election of a national leader on the basis ofhis or her image.Professional journalists do have a code of ethics(道德标准).Journalists make a judgment about what's safe and appropriate to report,which often involves difficult choices.German sociologist Max Weber distinguishes between“ethics of conviction”and “ethics of responsibility”.According to the latter (ethics of responsibility),journalists must take into account the foreseeable consequences of their reporting,and the impact it will have on society.The former,on the other hand,asks journalists to tell the truth,regardless of the consequences.According to Weber,both ideas of ethics should be considered.Without doubt,information is power,and the big owners of the mass media are very powerful people.Television and radio stations,newspapers,magazines,and websites are,largely,owned and controlled by profit­making businesses.It is not strange that their ideas will get promoted at times.It is my view that such power and responsibility should never be left in the hands of a few.I believe it is our responsibility as concerned citizens to make sure we are not merely passive viewers,readers or listeners.Together we can have a huge influence on the media by making our views known.7.What's the first paragraph mainly about?A.Responsibilities of the media.B.Influence of the media.C.History of the media.D.Problems of the media.8.We can learn from the third paragraph that .A.the media is more interested in politics than other fieldsB.forming social change is the main duty of the mediaC.the great power of the media is controlled by political figuresD.the media can affect politics by forming political figures' images9.As for“ethics of conviction” and “ethics of responsibility”,Max Weber thinks .A.most journalists don't have the right ethicsB.it is near impossible for journalists to obey both sets of ethicsC.the two sets of ethics shouldn't be regarded as opposed to each otherD.journalists shouldn't be limited by these ethics10.Which of the following statements is TRUE according to the passage?A.The mass media should be owned by the government.B.The media industry has developed into a new age in recent years.C.In most cases,journalists are more powerful than the owners of the media.D.The media tends to promote the ideas of their owners sometimes.Ⅱ.阅读七选五(共5小题;每小题2分,满分10分)(2019·江西省高安中学高二上学期期末)If your child is being bullied(欺负), there are ways to help him or her deal with it on a day­to­day basis and lessen its lasting effect.If your child tells you about a bully, focus on offering comfort and support, no matter how upset you are.Kids are not willing to tell adults about bullying because they feel embarrassed and ashamed. 11Sometimes kids feel like it's their own fault. 12 Some kids are afraid that if the bully finds out that they have told others, it will get worse.Others are worried that their parents won't believe them or do anything about it.13 Remind your child that he or she isn't alone.Emphasize that it's the bully who is behaving badly-not your fort your child and say that you will find out what to do about it together.Take it seriously if you hear that the bullying will get worse if the bully finds out that your child has told someone. 14 But in most cases, teachers are the best onesto contact first.If you've tried that and still want to speak to the bullying child's parents, it's best to do so in a context where a school official, such as a teacher, can mediate.15 Find out about the laws in your community.In certain cases, if you have serious concerns about your child's safety, you may need to contact legal authorities.A.Praise your child for being brave enough to talk about it.B.They also worry that their parents will be disappointed.C.Many kids don't tell anyone because they feel ashamed.D.They think that if they acted differently it wouldn't be happening.E.A bully can turn something into a serious thing for kids.F.Many countries have bullying laws and policies.G.Sometimes it's useful to find the bully's parents.Ⅲ.完形填空(共20小题;每小题1.5分,满分30分)What do you do when no one is

Nobel did not say why he wanted to reward scientists who “made the most important discovery” during the previous year.One can guess that he wanted to reward present.day innovation and not to give tombstone awards to Galileo,Hippocrates,and other scientists from centuries past。

单元综合检测1一、选择题(本题包括15小题,每小题3分,共45分)1.化学是以实验为基础的自然科学,化学实验设计和操作中必须十分重视师生安全问题和环境保护问题。

下列实验问题处理方法不.正确的是()A.制氧气时排水法收集氧气后出现倒吸现象,立即松开试管上的橡皮塞B.在气体发生装置上直接点燃乙炔气体时,必须先检验乙炔气体的纯度C.实验结束后将所有的废液倒入下水道排出实验室,以免污染实验室D.给试管中的液体加热时不时地移动试管或加入碎瓷片,以免暴沸伤人解析:选C。

A项中出现倒吸现象,立即松开试管上的橡皮塞,将反应器中气体放出,将倒吸的液体压回;B项中乙炔具有可燃性,点燃前应先验纯;C项实验结束后将所有的废液倒入废液缸,不能倒入下水道,因废液中可能有酸液将腐蚀管道;D项正确。

2.下列实验室有关操作中一定不.会引起爆炸的是()A.点燃甲烷和空气混合气B.光照氯气和甲烷混合气C.撞击硫磺和氯酸钾的混合物D.室温时在空气中点燃纯净的甲烷解析:选D。

点燃可燃性气体(如甲烷、氢气、一氧化碳等)和空气或氧气的混合气体,都有可能发生爆炸,因此点燃可燃性气体前要验纯;用强光直接照射氯气和甲烷混合气体时,也会发生爆炸;可燃物(如木炭、硫磺等)和强氧化剂(如氯酸钾等)的混合物受到撞击时会发生剧烈反应而引起爆炸;纯净的甲烷可以在空气或氧气中安静地燃烧。

3.下列实验或叙述不.符合绿色理念的是()A.实验室用H2O2代替KClO3制取O2B.用稀HNO3代替浓HNO3与Cu反应制取Cu(NO3)2C.工业上用H2O2代替NaClO3作氧化剂氧化Fe2+D.用KClO3代替MnO2在盖有表面皿的点滴板上制取Cl2并做Cl2与KBr、KI、FeSO4、NaOH等溶液的实验解析:选B。

用稀硝酸代替浓硝酸与Cu反应制取Cu(NO3)2仍会产生污染,不符合绿色理念。

4.下列做法正确的是()A.将浓硝酸保存在无色玻璃瓶中B.用镊子取出白磷置于水中进行切割C.把氯酸钾制氧气后的残渣倒入垃圾桶D.氢气还原氧化铜实验先加热再通氢气解析:选B。

由于浓硝酸见光或受热易分解,故将浓硝酸保存在无色玻璃瓶中是错误的,应该保存在棕色试剂瓶中;用镊子取出白磷置于水中进行切割是正确的,因为白磷的着火点低,这样可以避免切割时摩擦产生的热引起的自燃;氯酸钾制氧气后的残渣中含有未分解的氯酸钾及二氧化锰等强氧化剂,因此把氯酸钾制氧气后的残渣倒入垃圾桶易发生危险;氢气还原氧化铜实验先加热再通氢气可能引起爆炸,应该是先通氢气排净空气后再加热。

5.下列使用食醋的家庭小实验,不.可能成功的是()A.将食醋倒入有水垢的暖水瓶内,水垢会逐渐溶解而消失B.将食醋滴到纯碱里,有气泡产生C.将加碘盐加到混有食醋的米汤里,米汤显蓝色D.用食醋浸泡废干电池的锌片,锌片表面有气泡产生解析:选C。

本题涉及的考点为:醋酸的性质与生活常识。

加碘盐与食醋并不反应,所以米汤(含有淀粉)不显蓝色。

而淀粉碘化钾与加碘盐遇到食醋则显蓝色。

部分同学选错是误认为D选项是原电池反应,实际上只是金属锌与酸反应产生了H2。

6.“碳捕捉技术”是指通过一定的方法将工业生产中产生的CO2分离出来并利用。

如可利用NaOH溶液来“捕捉”CO2,其基本过程如下图所示(部分条件及物质未标出)。

下列有关该方法的叙述中正确的是(双选)( )A .能耗大是该方法的一大缺点B .整个过程中,只有一种物质可以循环利用C .“反应分离”环节中,分离物质的基本操作是蒸发结晶、过滤D .该方法可减少碳排放,捕捉到的CO 2还可用来制备甲醇等产品解析:选AD 。

A 项该方法中高温反应炉分离出CO 2,需要消耗较多能量;B 项整个过程中NaOH 和CaO 均可循环利用;C 项从捕捉室中得到的溶液中含有大量的NaHCO 3,加入CaO 后生成CaCO 3和NaOH ,通过过滤的方法即可分离;D 项捕捉到的CO 2可与H 2反应制备甲醇:CO 2+3H 2――————→一定条件CH 3OH +H 2O 。

7.下列关于亚甲基的说法正确的是( )A .亚甲基基团中碳元素的化合价跟甲基基团中碳元素的化合价相同B .亚甲基基团和甲基基团的氢原子都能被氯气中的氯原子取代C .亚甲基基团中碳元素的化合价是-2价D .亚甲基基团和甲基基团中的氢原子都不能被氯气中的氯原子取代解析:选B 。

“基”中,含自由基元素的化合价不确定,如下列亚甲基中C 元素的化合价有的相同,有的不同:Cl —C 0H 2—Cl CH 3—C -2H 2—CH 3CH 3—C -1H 2—F Cl —C 0H 2—F所以,A 、C 两项都不正确。

甲基、亚甲基、次甲基的化学性质都跟甲烷相似,都能发生取代反应,故B 项对,D 项错。

8.如图,实验桌上放置的两容器中有等体积的甲、乙两种液体。

几天后,两者的体积都明显减少,且甲比乙减少得多。

由此现象得出的正确结论是( )A .甲比乙易挥发B .甲的沸点比乙高C .甲的熔点比乙小D .甲与乙都能挥发解析:选D 。

考查液体的挥发性,属容易题。

甲、乙两容器中的液体虽然都是敞口放置,但甲容器是广口的,有利于液体的挥发,因此甲容器中的液体挥发得快,不一定是甲容器中的液体易挥发,更不能说明甲的沸点比乙高,也不能说明甲的熔点比乙小,只能说明甲与乙两种液体都能挥发。

9.实验室氢气还原氧化铜实验的试管壁上往往沾有少量的铜单质,如果你是一个实验管理员,你会选用下列什么试剂来清洗( )A .浓硫酸B .浓硝酸C .稀硝酸D .氯化铁溶液解析:选D 。

四种物质溶解铜的反应分别是:Cu +2H 2SO 4(浓)=====△CuSO 4+SO 2↑+2H 2O ;Cu +4HNO 3(浓)===Cu(NO 3)2+2NO 2↑+2H 2O ;3Cu +8HNO 3(稀)===3Cu(NO 3)2+2NO ↑+4H 2O ;2Fe 3++Cu===2Fe 2++Cu 2+。

从反应的条件、反应物的腐蚀性、生成物的毒性等方面来考虑,选择用铁盐溶液最好。

10.实验室常用氢氧化钠溶液吸收氯化氢尾气,以防止环境污染。

下列既能吸收尾气,又能防止溶液倒吸的装置是( )解析:选B 。

防止溶液倒吸是考试中的热点。

A 装置虽然能防止倒吸,但会有氯化氢逸入空气而造成环境污染。

C 、D 装置中的进气管插入液面以下,不能起到防止倒吸的作用。

11.一定条件下,电解较稀的硫酸,其还原产物为双氧水,该原理可用于制取双氧水,其电解的化学方程式为:3H 2O +3O 2===O 3+3H 2O 2。

下列有关说法正确的是( )A .电解池的阳极生成双氧水,阴极生成臭氧B .电解池中硫酸溶液的pH 保持不变C .产生臭氧的电极反应式为3H 2O -6e -===O 3+6H +D .产生双氧水的电极反应式为2H 2O -2e -===H 2O 2+2H +解析:选C 。

由H 2O 2为还原产物,可知反应的过程可表示为:。

反应消耗水,溶液的pH 减小。

12.下列化学反应,不.符合绿色化学概念的是( ) A .消除硫酸厂的尾气排放:SO 2+2NH 3+H 2O===(NH 4)2SO 3B .消除制硝酸工业尾气的氮氧化物污染:NO 2+NO +2NaOH===2NaNO 2+H 2OC .制CuSO 4:Cu +2H 2SO 4(浓)=====△CuSO 4+SO 2↑+2H 2OD .制CuSO 4:2Cu +O 2=====△2CuO CuO +H 2SO 4(稀)===CuSO 4+H 2O解析:选C 。

“绿色化学”要求减少和消除工业生产对环境的污染。

A 、B 选项的化学反应是对有害气体的吸收,符合“绿色化学”要求。

C 、D 的目的是制硫酸铜,C 中产生有毒的气体SO 2,会造成大气污染。

对比分析会发现D 要比C 节约原料又不产生有害气体。

所以,最不符合绿色化学概念的是C 。

13.“绿色化学实验”进课堂,某化学教师为“氯气与金属钠反应”设计了如图装置与操作以替代相关的课本实验。

实验操作:钠与氯气反应的装置可作如图改进,将一根玻璃管与氯气发生器相连,玻璃管内放一块黄豆粒大的金属钠(已吸净煤油),玻璃管尾部塞一团浸有NaOH 溶液的棉花球。

先给钠预热,到钠熔融成圆球时,撤火、通入氯气,即可见钠着火燃烧,生成大量白烟。

以下叙述中错误的是( )A .反应生成的大量白烟是氯化钠晶体B .玻璃管尾部塞一团浸有NaOH 溶液的棉球是用于吸收过量的氯气,以免其污染空气C .钠着火燃烧产生苍白色火焰D .若在棉球外沿滴一滴淀粉碘化钾溶液,可据其颜色变化判断氯气是否被碱液完全吸收解析:选C 。

根据题目信息,氯气与金属钠反应产生了NaCl 固体,对应的现象为产生白烟。

14.下列实验操作正确的是( )解析:选C。

使用酒精灯要注意:不能用嘴吹灭酒精灯;不能在点燃时添酒精,酒精不能超过酒精灯容量的2/3;绝对禁止用燃着的酒精灯去点燃另一盏灯;托盘天平称量物体时,其质量只能精确到0.1 g;给试管中的液体加热,液体体积不超过试管容积的1/3,与桌面成45°角,试管夹夹在试管中上部;量筒规格应略大于所量取的液体体积,以减小误差。

15.如下图所示的装置,C、D、E、F、X、Y都是惰性电极。

将电源接通后,向乙中滴入酚酞试液,在F极附近显红色。

则以下说法不.正确的是()A.电源B极是负极B.甲、乙装置的C、D、E、F电极均有单质生成,其物质的量之比为1∶2∶2∶2 C.欲用丙装置给铜镀银,H应该是Ag,电镀液是AgNO3溶液D.装置丁中Y极附近红褐色变深,说明氢氧化铁胶粒带正电荷解析:选C。

本题综合性较强。

由乙装置F极附近显红色,可知F极发生反应2H++2e-===H2↑,F极为阴极,故电源A为正极,B为负极,其他可解。

二、非选择题(本题包括5小题,共55分)16.(8分)请根据下列实验要求填空:(1)分离饱和食盐水和泥沙的混合物,分离方法为______________,所用的玻璃仪器有__________________。

(2)从碘水里提取并得到固体碘,应先进行________操作,再进行________操作。
