2021年高二下学期暑假作业英语试题(1) 含答案

一阅读理解(共两节,满分30分)第一节(共10小题; 每小题2分,满分20分)AAnne is six years older than me. Growing up, we were very poor, and my mother worked evenings at a factory in a small town. Not seeing my mother much, Anne looked after me and my younger sister. During those hard years, Anne was always there for me, not only as a big sister, but as a mother and my best friend.When I was seventeen and had no money, I thought my only chance of going to college was if I could win a scholarship. I had an important interview for such an award. Anne at that time was struggling, surviving on a part-time job as she put herself through the local munity college after serving in the army. I told her of my interview. I asked her advice on what to wear and showed her my best outfit (装束) and how I planned to be careful, how I sat so that the hole in the bottom of my shoes would not be seen, but I wasn’t sure what I would do if it rained.Anne suggested that we go shopping, and we took the bus to the JCPenney store. We found a beautiful pair of leather shoes on sale. She told me to try them on, but I thought it was just for fun as neither of us had ever owned anything that expensive before. But Anne handed me the boxed shoes and said, “Here, I’ll buy these for you.”“But . . .” was all I could say.“You deserve them,” she replied. “This interview is important. I want to see you get that scholarship.”I was speechless as I knew this was a lot of money for her, and she would probably have to eat nothing but noodles for at least a month.I went to the interview and crossed my legs so that my beautiful new shoes shone with pride. I won the scholarship and became an engineer. Although they were nice leather everyday shoes, I didn’t wear them much because they were so special. Now, after 20 years have passed, I still have that pair of shoes with me, and I just wear them on those occasions when I need to feel special.1. When the author was 17, Anne _____.A. was serving in the armyB. was continuing her studyC. was a salesgirl at the JCPenney storeD. was working in a small pany2. The author went to the interview _____.A. acpanied by AnneB. wearing a pair of worn shoesC. with confidenceD. with great anxiety3. What would be the best title for the passage?A. An important interviewB. A special pair of new shoesC. Memories of poor childhoodD. Lifelong gratitude to a friendBLooking good, feeling goodBorn to a model mom and a suit maker dad, fashion was actually in my blood.I always had a strong desire to dress in a certain way and to stand out from the crowd.Imademy own toys whenI was a young child and sewed my first skirt at just 10 years old.Afriend’s mother took one look at my skirt and told me that I should be a patternmaker. In high school I started making my own clothes, mostly changing other things because I never liked anything how it was when I bought it. During the last two years of school, I worked part-time for a small business that made hand-painted silk clothingand bags. The owner became the teacher who got me into design in the first place. Another useful bit of work experience then came when I worked at a showroom during fashion week andfound it very exciting. From there I worked at a top clothing store while I got my business started.For my business I started out with the idea that everything I did would be hand-made and one-of-a-kind, specially made for one individual who hopefully had the same tastes as me. Every morning I jumped out of bed,went to my studio and worked on my projects. This just showed how enthusiastic I felt about my work. And at night I even dreamed of new designs!Fashion design is functional art. What I mean is that it’s something close to you and something you can touch and feel, and actually interact with. My advice to any young person who wants to be a fashion designer is to get the basic skills early on, such as sewing and pattern-making. Even if you end up specializing, it’s really important to understand all aspects of design in order to make high-quality clothes.Also, if you dream of having your own clothing line, the best thing to do is start wearing your clothes. You have to try and do this because that’s the way you’re going to develop something that’s all yours andunlike anyone else’s. I pas sionately believe that the right clothing can make people feel better and give them more confidence.4. When the author was in high school, she ______.A. wore the latest fashionsB.was fondofhand-painted clothingC. began to make clothes on her ownD. dressed in the same way as her classmates5. What does the underlined word “functional” in Paragraph 4 probably mean?A. Practical.B. Standard.C. Decorative.D. plex.6. What advice does the author give to those who want to be fashion designers?A. Creating basic designs in high school.B. Wearinghigh-quality clothes all the time.C. Looking at what their friends are wearing.D. Deciding what is unique about their clothes.7. According to the author, well-designed clothes _______.A.cost people a lot of moneyB.bring people great successC. provide people with popular tasteD. helppeoplefeel sure ofthemselves第二节(共5小题;每小题2分,共10分)根据短文内容,从短文后的七个选项中选出能填入空白处的最佳选项。

河南省罗山高中高二化学下学期暑假自主学习考点自检测

脂肪烃 1、在密闭容器中某气态烃和氧气按一定比例混合,点火爆炸后恢复到原温度(20 ℃),压强减小至原来的一半,若加NaOH 溶液则气体全部被吸收,则此烃为( )A .C 3H 8B .C 4H 8C .C 2H 6D .C 3H 6【答案】A【解析】设该烃的分子式为C x H y ,则C x H y +(x +4Y )O 2=x CO 2+2Y H 2O ,反应完全进行,又因为燃烧后,压强减小至原来的一半,则x =21 (1+x +4Y ),即x =1+4Y ,只有C 3H 8满足该等式。

2、绕月探测工程“嫦娥一号”卫星已成功完成在轨运行和探测任务,获得了大量科学探测数据,科学家对数据进行了分析,发现月球形成时可能存在稀薄的原始大气层,主要由氖、氢、氦、氩等气体组成,不含甲烷等碳氢化合物。

下列关于碳氢化合物的叙述正确的是( )A .碳氢化合物的通式为C n H 2n +2B .燃烧产物为二氧化碳和水的化合物一定是碳氢化合物C .碳原子间以单键相连的烃是烷烃D .碳氢化合物分子的相对分子质量一定是偶数【答案】D【解析】C n H 2n +2是烷烃的通式,A 项错误;燃烧产物为二氧化碳和水的化合物不一定是碳氢化合物,化学式为C x H y O z 的有机物的燃烧产物也是二氧化碳和水,B 项错误;碳原子间全部以单键相连的链烃才是烷烃,C 项错误;因为碳原子的相对原子质量(12)为偶数,烃分子中的氢原子个数也一定为偶数,所以碳氢化合物分子的相对分子质量一定是偶数是正确的。

3、下列有机物命名正确的是( )A .3-甲基-3-丁烯B .2,4-二甲苯C .2-甲基-3-异丙基戊烷D .2,3-二甲基戊烷【答案】D【解析】A 项按名称写为,命名2-甲基-1-丁烯;B 项显然错误,应是1,3-二甲苯或称为间二甲苯;C 项按名称写为,该物质应称为2,4-二甲基-3-乙基戊烷;D 项正确。

4、将0.2mol 丁烷完全燃烧后生成的气体全部缓慢通入0.5L2mol/LNaOH 溶液中,生成的Na 2CO 3和NaHCO 3的物质的量之比为( )A. 3:2B. 2:3 C .2:1 D. l :3【答案】D【解析】0.2mol 的丁烷完全燃烧生成0.8molCO 2,与0.5L×2mol/L=1mol 的NaOH 溶液完全反应,生成的Na2CO3和NaHCO3的物质的量设为x、y,根据元素守恒,可得x+y=0.8mol,2x+y=1mol,解得x=0.2mol,y=0.6mol,所以x:y=1:3,答案选D。

时遁市安宁阳光实验学校难溶电解质的溶解平衡1、把Ca(0H)2放入蒸馏水中,—段时间后达到平衡:下列说法正确的是( )。

A.向溶液中加CaO,并恢复原温度时,溶液的pH升高B.给溶液加热,溶液的pH升高C.向溶液中加入Na2CO3溶液,其中固体质量增加D.向溶液中加入少量NaOH固体,Ca(0H)2固体质量不变【答案】C【解析】A、加入CaO后,平衡逆向移动,Ca(0H)2固体质量增加,但温度不变,此时溶液仍是饱和溶液,所以溶液的pH不变,错误;B、Ca(0H)2的溶解平衡为放热反应,所以升温使平衡逆向移动,氢氧根离子浓度减小,溶液的pH减小,错误;C、向溶液中加入Na2CO3溶液,钙离子浓度减小,使平衡正向移动,Ca(0H)2固体转化为CaCO3固体,固体质量增加,正确,D、向溶液中加入少量NaOH固体,氢氧根离子浓度增大,使平衡逆向移动,Ca(0H)2固体质量增加,错误,答案选C。

2、一定温度下,向含有AgCl(s)的饱和AgCl溶液中加水,下列叙述正确的是()A.AgCl的溶解度增大B.AgCl的溶解度增大,K sp不变C.C(Ag+)增大D.AgCl的溶解度、K sp均不变【答案】D 【解析】解:加入水多,溶解的氯化银质量多,AgCl的溶解度是指一定温度下,100g水中溶解AgCl的最大质量,与加入水的多少无关,所以加入水后氯化银的溶解度不变;AgCl的Ksp只受温度影响,所以温度不变,AgCl的溶解度、Ksp不变,故选D.3、已知,常温下,K SP(AgCl)=1.8×10-10mol2·L-2,K SP(AgI)=8.3×10-17mol2·L-2,下列叙述中,正确的是()A. 常温下,AgCl在饱和NaCl溶液中的K SP比在纯水中的K SP小B. 向AgCl的悬浊液中加入KI溶液,沉淀由白色转化为黄色C. 将0.001 mol·L-1的AgNO3溶液滴入KCl和KI的混合溶液中,一定先产生AgI沉淀D. 向AgCl的饱和溶液中加入NaCl晶体,有AgCl析出且溶液中c(Ag+)=c(Cl-)【答案】B【解析】4、下表是3种物质的溶解度(20℃),下列说法中正确的是()物质MgCl2Mg(OH)2MgCO3溶解度(g/100g)74 0.000 84 0.01A.已知MgCO3的K sp=6.82×10﹣6 mol2·L﹣2,则所有含有固体MgCO3的溶液中,都有c(Mg2+)=c(CO32﹣),且c(Mg2+)·c(CO32﹣)=6.82×10﹣6 mol2·L﹣2 B.除去粗盐中含有的MgCl2杂质,最佳除杂试剂为Na2CO3溶液C.将表中三种物质与水混合,加热、灼烧,最终的固体产物相同D.用石灰水处理含有Mg2+和HCO3﹣的硬水,发生的离子反应方程式为Mg2++2HCO3﹣+Ca2++2OH﹣═CaCO3↓+MgCO3↓+2H2O【答案】C【解析】A、c(Mg2+)·c(CO32﹣)=“6.82“×10﹣6,但不一定都有c(Mg2+)=c (CO32﹣),A错误;B、溶解度:Mg(OH)2<MgCO3,故除去粗盐中含有的MgCl2杂质,最佳除杂试剂为NaOH,C错误;C、MgCl2+2H2O Mg (OH )2+2HCl,加热MgCl2溶液,平衡向右移动,最后打破平衡,蒸干后得到Mg(OH)2,灼烧Mg(OH)2,Mg(OH)2分解得到MgO,MgCO3+2H2O Mg(OH)2+H2CO3,加热MgCO3溶液,平衡向右移动,最后打破平衡,蒸干后得到Mg(OH)2,灼烧后,也得到MgO,故三者最终的固体产物相同,B正确;D、用石灰水处理含有Mg2+和HCO3﹣的硬水,发生的离子反应方程式为Mg2++2HCO3﹣+2Ca2++4OH﹣=2CaCO3↓+Mg(OH)2↓+2H2O,D错误;故选C.5、现在含MgCl2、AlCl 3均为n mol的混合溶液,向其中滴NaOH溶液至过量.加入NaOH溶液的物质的量与生成沉淀的物质的量的关系正确的是(离子形成沉淀或沉淀的溶解与溶液pH的关系如下表)离子Mg2+Al3+物质Al(OH)3开始沉淀时的pH 8.93 3.56 开始溶解时的pH 8.04完全沉淀时的pH 10.92 4.89 完全溶解时的pH 12.04()A. B.C.D.【答案】C【解析】当Al3+完全沉淀时,溶液的pH=8.04,而镁离子开始沉淀的pH=8.93,则Al3+完全沉淀时Mg2+还没有开始沉淀;即:当Mg2+开始沉淀时,已经有部分氢氧化铝开始溶解;镁离子完全沉淀的pH=10.92,、氢氧化铝完全溶解的pH=12.04,则当Mg2+完全沉淀时,氢氧化铝还没有完全被溶解,所以正确的图象应该是C;故选C.6、下列说法正确的是( )A.将密封有NO2的玻璃球浸泡在热水中,气体颜色会变浅B.向K2CrO4溶液中加入稀硫酸,溶液颜色由橙色变为黄色C.向盛有0.1mol/LMgCl2溶液的试管中加入NaOH溶液,有白色沉淀生成,再滴入0.1mol/L FeCl3溶液,沉淀最终变为红褐色D.向盛有Na2CO3溶液中的试管加入酚酞试液,溶液呈红色,再加入足量BaCl2溶液,产生白色沉淀,溶液仍然呈红色【答案】C【解析】解:A、反应2NO2N2O4是放热反应,加热平衡向逆向移动,颜色加深,不选A;B、反应Cr2O72-+H2O2CrO42-+2H+,加入硫酸,平衡逆向移动,颜色从黄色变为橙色,不选B;C、由于氢氧化铁的溶度积小于氢氧化镁,所以氢氧化镁白色沉淀可以和氯化铁反应生成氢氧化铁红褐色沉淀,选C;D、碳酸钠溶液中由于碳酸根离子水解而使溶液显碱性,加入氯化钡,碳酸钠和氯化钡反应生成碳酸钡沉淀和氯化钠,溶液的碱性减弱,颜色变浅,不选D。

综合测评卷02:新高二暑假作业(教师版)(150分钟150分)一、现代文阅读(35分)(一)现代文阅读Ⅰ(本题共5小题,19分)阅读下面的文字,完成下面小题。

材料一:线上与线下“二元结构”构成了我国网络文学批评的整体格局。

两大批评阵地均十分活跃,它们特色各具却功能分殊,如不同传播路径让批评的影响力场域有别。

基于网络媒体强大的整合力,两大批评空间的互动与融通有其必要性,也具有必然性,未来的网络文学批评尤其需要建强线上批评阵地,以更好地贯彻“以读者为中心”的文学理念,增强网络文学批评的朝气和锐气,让人民大众成为网络文学审美及其评判的真正主体。

网络文学的线上批评一直都十分活跃而多产,且十分有效,批评的有限和疲弱仅适于线下批评,即由专业批评家所做的平面媒体发表、纸介传播的网络文学批评。

线上批评与线下批评的“空间”落差,影响的不仅是批评本身的业态平衡,更影响整个网络文学的可持续发展。

因而,需要重新识辨网络文学批评的“线上与线下”问题,以助推外在的“空间区隔”走向内在的“批评交融”。

网络文学既然是“在线写作”“在线阅读”,当然就会有“在线批评”;而在线就是“直接在场”,它能够对网络创作和网文阅读产生“非常重大的影响”。

后来又有研究者撰文指出:“坚持加强网络文学的在线批评与发现、提升中国经验,创新文学批评理论关系密切。

网络文学的在线批评,于广大网络写手有普及文学创作常识的作用,促使他们提高文学创作与创新意识;同时作为评家自己,也可以通过及时的文学批评锻炼艺术感悟力,在文学文本与文学接受者之间起到中介、桥梁和纽带的作用,以增加接受者审美快感的强度和深度。

”另一种批评存活空间是为传统学人更熟悉的线下批评,即由批评家在平面媒体(书报刊)发表的网络文学批评,或者是由政府职能部门和学术社团机构组织的网络文学研讨活动和理论批评会议。

这一批评空间不仅享有行政、学术、传媒之话语权力,还背靠千百年文学传统的观念积淀,理论资源十分丰富,形成了自己的评价标准和批评范式。

As soon as he starts to draw the crowd,a zoo keeper grabs him and drags him into his office. The zoo keeper explains to the mimic that the zoo's most popular attraction,a gorilla(大猩猩),has died suddenly and the keeper fears that attendance at the zoo will fall off. He offers the mimic a job to dress up as the gorilla until they can get another one. The mimic accepts.So the next morning the mimic puts on the gorilla suit and enters the cage before the crowd comes. He discovers that it's a great job. He can sleep all he wants,play and make fun of people and he draws bigger crowds than he ever did as a mimic. However,eventually the crowds tire of him and he tires of just swinging on wires. He begins to notice that the people are paying more attention to the lion inthe cage next to his. Not wanting to lose the attention of his audience,he climbs to the top of his cage,crawls across a partition(隔离物),and dangles from the top to the lion's cage. Of course,this makes the lion very angry,but the crowd loves it.At the end of the day the zoo keeper comes and gives the mimic a raise for being such a good attraction. Well,this goes on for some time-the mimic keeps taunting the lion,the crowds grow larger,and his salary keeps going up. Then one terrible day when he is dangling over the angry lion he slips and falls. The mimic is terrified.The lion gathers itself and prepares to attack. The mimic is so scared that he begins to run round and round the cage with the lion close behind. Finally,the mimic starts screaming and yelling,“Help me,help me!”But the lion is quick and attacks. The mimic soon finds himself flat on his back looking up at the angry lion and the lion says,“Shut up,you idiot!Do you want to get us both fired?”36.The mimic visits the zoo to________.A.take care of the dying gorilla B.beg some money from the zoo keeperC.ask for a job there D.perform and earn some money there37.The zoo keeper offers the mimic a job to act as the gorilla because________.A.it is more expensive to hire a real gorillaB.the real gorilla died but the keeper does not want to lose its visitorsC.he likes the mimic's performanceD.he wants to help the mimic who is out of work38.What does the mimic feel about the new job at first?A.He likes it because he has enough freedom in the job.B.He likes it but he prefers to working as a mimic.C.He doesn't like it for people do not respect him.D.He doesn't like it because he gets little pay.39.The mimic climbs to the lion's cage because________.A.he finds it more interesting to climb the cageB.he wants to play with the lionC.he wants to attract the attention of his audienceD.he has never seen a lion before40.What does the passage mainly tell us?A. The mimic and his jobB. The mimic and his successC. The actor and the mimicD. The mimic and his animalsWe are all interested in equality, but while some people try to protect the school and examination system in the name of equality, others, still in the name of equality, want only to destroy it.Any society which is interested in equality of opportunity and standards of achievement must regularly test its pupils. The standards may be changed ---- no examination is perfect ---- but to have no external(外部的)tests or examinations would mean the end of equality and of standards. There are groups of people who oppose this view and who do not believe either in external examinations or in any controls in schools or on teachers. This would mean that everything would depend on luck since every pupil would depend on the efficiency, the ideal and the purpose of each teacher.Without external examinations, employers will look for employees from the highly respected schools and from families known to them ---- a form of favoritism will replace equality. At the moment, the bright child from an ill-respected school can show certificates(证书)to prove he or she is suitable for a job, while the lack of a certificate shows the unsuitability of a dull child attending a well - respected school. This defense of excellence and opportunity would disappear if external examinations were taken away, and the bright child from a poor family would be a prisoner of his or her school's fame, unable to compete for employment with the child from the favored school.The opponents(对手)of the examination system suggest that examinations are an evil force because they show differences between pupils. According to these people, there must be no special, different, academic class. They have even suggested that there should be no form of difference in sport or any other area: all jobs or posts should be filled by unsystematic selection. The selection would be made by people who themselves are probably selected by some computer.These people are not just against school organization, but are at war with the whole idea of modem competitive society and they are using children in schools for their destructive purposes. There is no reason why we should allow such people to determine the way our schools are organized when it is to the obvious disadvantage of the pupils, of the schools and of our society as a whole.41.According to the passage, the writer thinks that ________.A. changing the standards could mean the end of equalityB. standards must keep changing in order to achieve equalityC. there would be no standards without external examinationsD. we cannot have standards because examinations are not perfect42.In the writer's opinion, what would happen if external examinations were taken away?A. There would be no more opportunities and no more excellence.B. Children from poor families would not be able to change schools.C. Going to a favored school should be the only way to get a good job.D. Schools for bright children would lose their fame.43.The situation at the moment is that ________.A. many children who are suitable for a job have no proof of their suitabilityB. a school's fame is not important, as long as a child has a certificate.C. children attending well - respected schools need not get certificates.D. a bright child doesn't need a certificate a t all to get a good job.44.Which of the following sentences is TRUE?A. Most students from poor families can't get a good job.B. Some people are using students to destroy our society.C. The writer thinks it a good way to choose a job by computer.D. The opponents of the examination want to reorganize schools.45.The opponents would agree that _________.A. computers should be selected to take over many jobsB. particular people should not be chosen for particular jobsC. well-respected schools should be got rid of as soon as possibleD. the students are not equally treated if they take external examinationsIn tradition (传统的) education, the teacher may feel that the students are not very grown up. Usually, teachers are older than students, and teachers feel that students are young and do not know much about the world. The teachers feel that they must tell the students what to do most of the time, and that they must also make the students study specific (特殊的) things. In open education, the teacher’s methods are very different. These teachers feel that the students are human beings (人) first, and students second. They expect the students to be responsible for the things that they do, just as adults are. A student’s ideas and feelings are just as important as the teacher’s. The teacher allows the students to decide what they want to do, and does not make them study what they do not want to. The teacher lets them decide what to study and how much to study. I t’s very important for the teacher to show how he or she feels about students.46.Which is the topic for the passage?A. Traditional EducationB. Open EducationC. The Students Are Human Beings FirstD. Two Kinds of Different Education47.What’s the theory of open education?A. The students are human beings first, and students second.B. The students should be responsible for what they do.C. The students’ ideas and feelings are very important.D. The teachers should allow the students to do what they want to do.48.In traditional education, the teachers consider that __________.A. they should praise the students all the timeB. they should tell the students what to do all the timeC. the students should know much about the worldD. the students should learn much about the world from their teachers49.We can infer (推断) that ____________.A. students needn’t study as hard as they did beforeB. students can learn more about the world in open educationC. most of the teachers don’t agree with the idea of open educationD. most of the students prefer traditional education to open educationI have always loved kids. However, the children here at Shanti Bhavan are unlike any that I have ever met. They have a strong drive and determination and are thankful for the wonderful opportunity they have been given. While at Shanti Bhavan, I taught 3rd graders writing, language, and literature, 8th, 9th, and 10th graders public speaking, 9th and 10th graders basketball, and piano lessons. I found teaching the children was the most rewarding experience of my life. They are really fast learners and really have an interest in knowledge. It was easy to get on with such polite, well-mannered, and hard-working students. They dream big and I only hope that I can continue to be a part of helping them achieve their goals. As far as my day-to-day living went, I was perfectly comfortable here and came to consider it as a second home. My room was clean and comfortable and the staff could not have been nicer.In addition, I really appreciated the support of all the teachers. They were so welcoming and kind that it truly cleared away my fears and culture shock. They often gave me advice and befriended me and I owe much to them for their warmth.I honestly feel that Shanti Bhavan is the most beautiful place on earth. It has love and learning, and I am very sad to be leaving. I am looking forward to my return to this newly found family as soon as possible. Thank you so much Miss Beena and Mrs. Law for all of your love and support. The experience that I worked with them will always come into my mind. This has been the greatest experience of my life. 50.What can we learn from the first paragraph?A. Kids liked basketball lessons best.B. Kids at Shanti Bhavan helped the author a lot.C. The author is a fast learner and dreams big.D. The author taught different lessons at the same time.51.What does the author think of the students at Shanti Bhavan?A. GenerousB. CleverC. BraveD.

The author will come back soon.B. The author has decided to settle at Shanti Bhavan.C. The author once felt uneasy at Shanti Bhavan.D. The author was forced to come to Shanti Bhavan at first.A Tchaikovsky concerto(协奏曲)is what made Romel Joseph fall in love with the violin.He learned how to play in Haiti, where he was born, but a Fulbright scholarship brought him to the United States, and he finally earned a master’s degree, reports CBS News reporter Katie Couric. Music had changed his life. He wanted to do the same for the children of Haiti.Joseph built a school in Port-au-Prince nearly 20 years ago. He was on the third floor when suddenly “It was like boom boom boom and everything just opened,” Joseph said. “And the next thing I knew I was on the ground.”Blind since birth, Joseph tried to feel his way out, but was pinned(夹)beneath heavy concrete(混凝土). He remained trapped for 18 hours. He prays that his new wife, seven months pregnant(怀孕的), will be found.He is now being treated at Miami’s Jackson Memorial Hospital for two injured legs and an arm. Joseph wonders if he’ll ever play the violin again. He can feel sensation(知觉)in his fingertips.

That’s more or less what happened the night that Nashville Police Officer Floyd Hyde was on duty.“I was on the way to a personal-injury accident in West Nashville. As I got onto Highway 40, blue lights and siren(警笛) going, I fell in behind a gold Pontiac Firebird that suddenly seemed to take off quickly down the highway. The driver somehow panicked at the sight of me. He was going more than a hundred miles an hour and began passing cars on the shoulder.”But Hyde couldn’t go after him. Taking care of injured people is always more important than worrying about speeders, so the officer had to stay on his way to the accident. But he did try to keep the Firebird in sight as he drove, hoping another nearby unit would be able to step in and stop the speeding car. As it turned out, keeping the Firebird insight was not that difficult. Every turn the Pontiac made was the very turn the officer needed to get to the accident scene.Hyde followed the Pontiac all the way to his destination(目的地). At that point he found another unit had already arrived at the accident scene. His help wasn’t needed. Now he was free to try to stop the driver of the firebird, who by this time had developed something new to panick about.“Just about that time,”Hyde says, “I saw fire ing out from under that car, with blue smoke and oil going everywhere. He’s blown his engine. Now he had to stop.”“After I arrested him, I asked him why he was running. He told me he didn’t have a driver’s licenseThat accident cost the driver of the Firebird plenty—a thousand dollars for the new engine—not to mention the charges for driving withouta license, attempting to run away, and dangerous driving.31. The meaning of “panicked” in paragraph 2 is related to _______.A. happyB. fearC. angerD. hate32. Why did the driver of the Firebird suddenly speed down the highway?A.

Today it is estimated that some 260 million people speak it as a native language, mainly in the United States, Canada, Great Britain, Ireland, South Africa, Australia and New Zealand. In addition to the standard varieties of English found in these areas, there are a great many regional and social varieties of the language as well as various levels of usage that are employed both in its spoken and written forms.In fact, it is impossible to estimate the number of people in the world who have acquired an adequate(足够的) working knowledge of English in addition to their own languages. The purpose for English learning and the situations in which such learning takes place are so varied that it is difficult to explain and still more difficult to judge what forms an adequate working knowledge for each situation.The main reason for the widespread demand for English is its present-day importance as a world language. Besides serving the indefinite needs of its native speakers, English is a language in which some of important works in science, technology, and other fields are beingproduced, and not always by native speakers. It is widely used for such purposes as meteorological and airport munications, international conferences, and the spread of information over the radio and television networks of many nations. It is a language of wider munication for a number of developing countries, especially former British colonies. Many of these countries have multilingual populations and need a language for internal munication in such matters as government, merce, industry, law and education as well as for international munication and for entrance to the scientific and technological developments in the West.36. What would be the best title for this passage?A. The Difficulties of Learning EnglishB. International municationsC. The Standard Varieties of EnglishD. English as a World Language37. Which of the following statements is NOT true?A. Some 260 million people in the world have an adequate workingknowledge of English.B. There are some 260 million native speakers of English in the world.C. It is almost impossible to estimate the number of people with anadequate working knowledge of English.D.

It is used in former British colonies.C. It serves the needs of its native speakers.D. It is a world language that is used for international munication.39. What forms an adequate working knowledge of English?A. The ability to read a newspaper.B. It is difficult to judge because it differs for each situation.C. Being a multilingual.D. Being a native speaker.40. What type of developing countries would be most likely to use English?A. Those geographically close to the United States.B.
