第二部分阅读理解(共两节,满分40分)第一节 (共10小题;每小题2分,满分30分)阅读下列短文,从每题所给的四个选项(A、B、C和 D )中,选出最佳选项,并在答题卡上将该项涂黑。
AWill it matter if you don't take your breakfast? A short time ago, a test was given in the United States. People of different ages, from 12 to 83, were asked to have a test. During the test, these people were given all kinds of breakfasts, and sometimes they got no breakfast at all. Scientists wanted to see how welltheir bodies worked when they had eaten different kinds of breakfasts.The results show that if a person eats a right breakfast, he or she will work better than if he or she has no breakfast. If a student has fruit, eggs, bread and milk before going to school, he will learn more quickly and listen more carefully in class.The result is opposite to what some people think. Having no breakfast will not help you lose weight. This is because they are so hungry at noon they eat too much for lunch. They will gain weight instead of losing it. You will lose more weight if you reduce your other meals.21. During the test, the people were given_____________.A. no breakfast at allB. different foods or sometimes noneC. very rich breakfastsD. little food for breakfast22. The results show that __________________A. breakfast has great effect on work and studies.B. breakfast has little to do with a person's work.C. a person will work better if he only has fruit and milk.D. Girl students should have little for breakfast23. Which of the following is NOT right?A. It is bad for your health to have no breakfastB. Too little for breakfast and too much for lunch may make you fatter.C. If you don't eat much for lunch and supper, you may lose weight.D. The more breakfast you have, the more quickly you'll learn in class.BA new book called “Battle Hymn of the Tiger Mother” by Amy Chua has caused a debate (争论) about cultural differences in parenting. Amy Chua is a teacher in an American university and both of her parents are Chinese. In the book, Ms. Chua writes about how she taught her daughters. She told NBC television that she had a clear list of what her daughters were not allowed to do, such as having a play date, watching TV or playing computer games and getting any grade less than an A.Many people are against Amy Chua’s parenting style (风格), even her husband, who is American. They say it is rude and unfair to children. But she says her parents raised her and her three sisters in that way.Ms. Chua says after her younger daughter shouted “I hate my life! I hate you!” she decided to retreat because she was afraid of losing her daughter. But she also says American parents often have low expectations of their children’s abilities.“The debate is about what it means to be a successful parent and what it means to be a successful child,” said Stacy DeBroff, who has written four books on parenting. She says Amy Chua’s parenting style is not limited to Chinese families. It is a tradi-tional way of parenting among immigrants (移民). They hope to get a better future for their children.She also sees a risk (风险). When children have no time to be social or to develop their own interests, they might not develop other skills that they need to succeed in life. DeBroff advises parents to develop their own style of parenting and not just repeat the way they were raised.24. What do we learn about Amy Chua?A. She has three excellent daughters.B. She moved to the US at a young age.C. Her parents live together with her.D. Her husband dislikes her parenting style.25. The underlined word “retreat” in Paragraph 3 is closest in meaning to _____.A. go onB. give upC. go outD. give out26. According to Ms. DeBroff, _____.A. Amy Chua’s parenting style should be forbiddenB. Americans should learn from Amy ChuaC. parents should have their own parenting styleD. Amy Chua’s style is bad for children’s growth27.In which part of a newspaper can you read the passage?A . Business.B . Entertainment.C . Sports.D . Culture.CThere were smiling children all the way. Clearly they knew at what time the train passed their homes and they made it their business to stand along the railway, wave to complete strangers and cheer them up as they rushed towards Penang. Often whole families stood outside their homes and waved and smiled as if those on the trains were their favorite relatives. This is the simple village people of Malaysia.I was moved.I had always traveled to Malaysia by plane or car, so this was the first time I was on a train.I did not particularly(特别) relish the long train journey and had brought along a dozen magazines to read and reread. I looked about the train. There was not one familiar(熟悉的)face. I sighed and sat down to read my EconomicsIt was not long before the train was across the Causeway and in Malaysia. Johore Baru was just another city like Singapore, so I was tired of looking at the crowds of people as they hurried past. As we went beyond the city, I watched the straight rows of rubber trees and miles and miles of green. Then the first village came into sight. Immediately I came alive, I decided to wave back.From then on my journey became imeresting.I threw my magazines into the waste basket and decided to join in Malaysian life.Then everything came alive.The mountains seemed to speak to me.Even the trees were smiling.I stared t everything as if I was looking at it for the first time.The day passed fast and I even forgot to have my lunch until I felt hungry. I lookedat my watch and was surprised that it was 3:00 pm. Soon the train pulled up at Butterworth. I looked at the people all around me.They all looked beautiful. When my uncle arrive with a smile, I threw my around him to give him a warm hug.I had never done this before. He seemed surprised and then his weather-beaten face warmed up with a huge smile. We walked arm in arm to his car.I looked forward to the return journey.28.Why did the author mention the families standing outside their homes?A. To show the real life of village people.B. To show the friendliness of village peopleC.To show how village people found pleasureD. To show how village people warmed their relatives29.What does the underlined word“relish”mean in the second paragraph?A. chooseB. enjoyC. prepare forD. carry on30.How did the author probably feel after the train went beyond Johor Bahru?A. ExcitedB. UnsatisfiedC. DisappointedD. Bored31.What’s the best title of the text?A. My exciting journey to MalaysiaB. Scenery adding pleasure to my train tripC. My unforgettable train trip in ButterworthD. Waves and smiles cheering up my train tripDForeign visitors to the UK might be disappointed when they learn that not everyone there speaks like Harry Potter and his friends. Usually, there's an assumption(假设) by many non-Brits that everyone in Britain speaks with what's known as a Received Pronunciation (RP, 标准发音) accent, also called “the Queen's English”. However, while many people do talk this way, most Britons speak in their own regional accents.Scouse, Glaswegian and Black Country dialect– from Liverpool, Glasgow and the West Midlands –are just three of the countless non-RP accents that British people speak with. There are even differences in accents between towns or cities just 30 kilometers apart. What is even more disappointing is that not speaking in a RP accent may mean a British person is judged and even treated differently in their everyday life.In a study by The University of South Wales, videos of people reading a passage in three different UK accents were shown to a second group of people. The group then rated (对…作评估)how intelligent they thought the readers sounded. The lowest-rated accent was Brummie, native to people from Birmingham, a city whose accent is considered working class.However, there is no need to be disappointed though you are not speaking in an RP accent. In fact, doing the opposite may even give you strength.Kong Seong-jae, 25, is from Seoul. After studying in the UK, he picked up several regional accents. He's now famous for his online videos, where he shows off the various accents he's learned. “British people usually get really excited when I use some of their local dialect words, and they become much friendlier. I thinkit makes a bit of bond between local people and foreigners to speak in their local accent,” he said.So if you're working on perfecting your British accent, try to speak like someone from Liverpool, Glasgow or Birmingham. You may not sound like Harry Potter, but you are likely to make more friends.32.What can we learn from paragraph 1?A . Most Britons speak the Queen’s English.B . Non-Brits usually hold that all Britons speak in a RP accent.C . Foreign visitors are disappointed at their own spoken English.D . The dialect is less important than the RP accent.33.What do people think of the Brummie accent?A . It is closest to the RP accent.B . It belongs to the people of the working classC . It is smart and easy to understandD.It is preferred by foreign visitors to the UK.34.What does the underlined phrase “doing the opposite” in Paragraph 3 refer to?A . Speaking with regional accents.B . Speaking with the RP accent.C . Speaking with the Brummie accent.D . Speaking like Harry Potter.35.What is the passage mainly about?A . How much British people value the RP accent.B . A comparison between different British accents.C . A study about the most intelligent accent in BritainD .Some facts about the RP accent and regional accents in Britain .阅读第二节(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的最佳选项。

河南省郑州市第四中学2014-2015学年高一上学期期中考试语文试题一、现代文阅读。
(共9分,每小题3分)阅读下面的文字,完成1~3题。
血腥背后的人性光辉美国导演比尔〃古登塔格、丹〃斯塔曼联袂推出的纪录影片《南京》,用沉重的血色影像与鲜明的西方视角,刺痛了许多国人的心。
长期以,国人对南京大屠杀秉持的基本立场,是声泪俱下的控诉与义愤填膺的声讨。
表现这一屠城悲剧的中国影视作品,如吴子牛导演的《南京大屠杀》,也都通过血泪斑斑的镜头语言,反复强化了这样的道德立意:日本战争发动者罪孽深重,必须向中国人民谢罪。
即便是创作于近年的电影《东京审判》,虽然主创者在演员选择、台词设计和作品样式上都强调了国际化趋向,并以一定篇幅再现了作为东京审判焦点的南京大屠杀段落,但倾向性明显的民族情感仍然超越了对审判过程的客观呈现,这反而弱化了影片的真实力量。
从某种意义上说,创作者对主观情感的节制,体现我们在七十年后反思历史伤痛时所彰显的普世价值和理性,是中国电影人突破“抗日题材”电影瓶颈的要害所在。
不同于《辛德勒名单》《拯救大兵瑞恩》《兄弟连》等传统西方战争题材影片,《南京》更注重原始的真实。
作为纪录电影,它的价值,除了影片的创作者们搜集并呈现在银幕上一批新影像素材,更为确凿地证实南京大屠杀的历史惨况之外,两位美国导演还邀请演员扮演那些冒着生命危险拯救中国难民的西方人士,如德国人约翰〃拉贝、美国人明妮〃魏特琳等,以一种更为人性化和戏剧化的方式,让这部原本沉重、血腥的纪录片更易为普通观众所接受。
相比于中国纪录片在作品形态上的粗糙和单调,曾经荣获过奥斯卡奖的古登塔格和斯塔曼的确有更丰富的叙事经验与表现手段。
作者并不讳言《南京》的西方视角,在导演与中国观众的交流现场,他们多次表示这部作品是站在欧美文化界的立场上进行的观照与反思,更多强调国际安全区创立者的西方背景是他们的价值选择。
虽有观影者感喟《南京》因此而“温和陈腐,隔靴搔痒”,不足以震撼国内观众的内心世界,但若因这部影片着重于欧美人士主导的“世纪救援”,而对美国人的“救世主心态”心存不悦,便未免有些狭隘民族主义的过激心态。

河南省郑州市中牟县第一高级中学2023-2024学年高一上学期10月月考英语试题学校:___________姓名:___________班级:___________考号:___________一、阅读理解Affordable Beach V acation in CorfuCorfu, an island off the coast of Greece, offers visitors sunkissed shores with clear water and lots of beaches.Finding the Perfect BeachOur first pick is Sidari Beach. It’s a blue flag beach perfect for couples looking for a more private feel, as it’s far from bigger tourist destinations. Issos Beach makes for the perfect place for watching the sunset. Dassia Bay has a bit more water sports. Paleokastritsa is an amazing West Coast village with six beaches on offer, including Rovinia Beach.Getting around CorfuCorfu offers bike rentals and bus service as a cheaper alternative (替代) to taxis. The best time to visit Corfu is during the “shoulder season” in April/May. The weather isn’t as warm as the high seasons but it remains perfect. It is not crowded in this period, but you still need to book ahead of schedule as Corfu stays popular throughout the year.Eating Out For LessThere are a lot of well-priced restaurants but street food is also a big winner. Some popular choices are Souvlakia and Pita Gyros. There are also many cheeses special to Greece, including Tirokafteri and Ladotyri. Corfu also has many unbelievable desserts (甜食). Stazei Meli is a tourist favourite to give them a try.1.Which place is probably the best choice for couples?A.Sidari Beach.B.Dassia Bay.C.Issos Beach.D.Rovinia Beach.2.What are tourists required to do to visit Corfu?A.Rent a bike.B.Book in advance.C.Wear warm clothes.D.Set off in April/May.3.What do we know about Stazei Meli?A.It cooks popular dishes.B.It severs well-priced food.C.It produces special cheese.D.It sells amazing desserts.Peru is famously known as “Land of the Incas”. A trip to Peru has been on my wish list for quite a while. It was finally time for me to visit the country.My first day started in Lima, the capital of Peru. I met with the G Adventures representative (代表) here about the tour. G Adventures is an organization that helps you to connect with other like-minded people in small group-based travel adventures. They played a big part in helping to make Peru an unforgettable experience for me! In Lima, my representative discussed the plan of my tour, and I also had the chance to explore Lima in my own time, with many activities, including a city tour, show, biking tour, and more.Day two had me taking a flight from Lima to Cusco. Many people visit Cusco for shopping but for me, the main reason for spending a day or two in Cusco was to acclimatize (适应) to the altitude (海拔). As I’d decided to reach the wonder of Machu Picchu, acclimatizing became important to avoid altitude sickness. I was happy to spend a day exploring Cusco. Cusco was once the capital of the Inca Empire. Today, it’s famous for its artists, paintings, clothing and traditional instruments. There’s something for everyone in this city.The day finally came! Day three had me enjoying a lovely guided visit to Machu Picchu at sunrise. I had free time to explore the city on my own as well as with my guide. It was a lot to take in! I had to stop for a moment and felt the energy of such an ancient city. The history here was unbelievable and I will never forget my time here for as long as I live!4.What is the author’s attitude to G Adventures?A.Doubtful.B.Satisfied.C.Uninterested.D.Hopeful. 5.Why did the author stay in Cusco?A.To go shopping.B.To find a local guide.C.To get used to the high altitude.D.To do research about the Inca Empire. 6.How did the author feel when traveling around Machu Picchu?A.Full of excitement.B.Out of luck.C.Lost in doubt.D.Deep in regret.7.What is the best title for the text?A.My love of traveling B.My wonderful trip to PeruC.Peru: “Land of the Incas”.D.Traveling: the future of Peru.A small study out of Skidmore College examined the advantages of morning vs, evening exercise for both women and men. Paul, professor for health at Skidmore, led the study.“We had the groups divided into evening and morning groups,” he says. “We found women and men answered differently to different types of exercise depending on the time of the day, which surprised us.”The study showed that for women who want to lower blood pressure (血压), the risk of heart disease or reduce fat, morning exercise works best. Those women hoping for upper body muscle (肌肉) gains or mood (心情) improvement should consider evening exercise. For the men, the findings were somewhat different: Evening exercise lowers blood pressure, the risk of heart disease, and feelings of tiredness. But similar to women, they burn more fat with morning exercise.“For many people, the best time to exercise will depend on their chronotype,” says Heisz, author of Move the Body, Heal the Mind.“Chronotype is your body’s natural habit to sleep at a certain time—it’s what decides whether you’re a night owl or an early bird. For the 25% of the population that considers themselves a night owl, getting both enough sleep and enough exercise can be difficult,” adds Heisz.He continues, “Sleep—which provides your body the necessary time to recover (恢复) and make gains from exercise—should always be the first choice. When it comes to exercise, regardless of research on the advantages of certain exercises at particular times of the day, your results will not be good if it doesn’t allow enough time for sleep.”8.What can women get by doing evening exercise according to the study?A.A fat loss.B.A good mood.C.A lower blood pressure.D.A smaller risk of heart disease.9.What does the author intend to do in paragraph 5?A.Give an example.B.Tell the difference.C.Do an experiment.D.Explain a term.10.What does Heisz think is important to achieve good results of exercise?A.Enough sleep.B.Low-fat food.C.Plenty of water.D.Lots of exercise.11.What is the best title for the text?A.A Night Owl or An Early BirdB.Why Fitness Plan Being ImportantC.How to Change Your Exercise TimeD.The Best Time of a Day to ExercisePhysical education, or PE, isn’t required for all high school students. In some schools, it isn’t offered for some different reasons. But should high school students have physical education? The answer is certainly “yes”.Today many people don’t do sports. But as is known to all. doing sports is very important for an adult. Teaching teens the importance of a healthy lifestyle and making fitness plans now can help teens put exercise in the first place as an adult.High school isn’t that easy. Many students are under a lot of stress. Stress can be harmful to a student’s studies and life. Doing sports can help them deal with stress better, helping them live a happier life at school.The American Heart Association says that 10 million kids and teens suffer from obesity (肥胖). Teens should get 60 minutes of physical activity per day to control their weight and to help their bones get stronger. The increase in activities that don’t get teens to move around, such as computer games, means many teens don’t get their required exercise. PE classes act as a public health measure (措施) to encourage physical activities and help teens have healthy weights.Not doing sports increases teens’ hazard of developing many diseases. An active lifestyle offers a good way of protection from these health problems. As much as 75 percent of health-care spending goes toward treating medical conditions that can be prevented by lifestyle changes, according to the American College of Sports Medicine.According to the President’s Council on Fitness, Sports and Nutrition (PCFSN), students who performed five hours of physical activities each week improved their academic (学业的) performance. Students from programs with no physical activity, who used the extra time for classroom study, did not perform better on tests than those who gave up some study time in support of physical education.12.According to Paragraph 2, what does physical education in high school mean?A.Making teens attach importance to ęxercise later.B.Removing the stress faced by teens at school.C.Getting teens to encourage adults to exercise.D.Helping teens learn to make good plans13.What does the underlined word “hazard” in Paragraph 5 mean?A.Happiness.B.Risk.C.Safety.D.Sadness.A.means making students choose between sports and studiesB.helps students make good use of all their timeC.means students adjust to their studies betterD.helps students do better in their studies15.What is the text mainly about?A.Why high school students should receive physical education.B.Why some schools consider physical education important.C.How schools can help students love doing sports.D.How high school students can live a better life.二、七选五Spring and summer are the best seasons of the year for lots of activities, especially jogging(慢跑). This kind of running is the choice of many people who live in the city, work in the office and want to keep healthy. 161. Make good preparations before jogging.17 There, you’ll have an opportunity to find and buy all the necessary sportsware. Pay attention to the selection of jogging shoes, if you don’t want to suffer from the feeling of heaviness, pain and leg swelling after the run. With all these pieces of wisdom. your body will be truly grateful to you.2. Do fitting warming-up activitiesEvery runner, especially the beginners should know that all physical activities without proper warming up can cause a terrible pain and result in harm to muscles. It will probably lead to a final discomfort in your body or even disease. 18 Actually, it usually just takes you 15 minutes to increase the range of motion of our joints and warm up every muscle of the body.3.19 When running, you usually feel physical and mental pleasure. Sometimes this pleasure can be replaced by negative feelings or even some kind of pain. No matter how healthy you’re, you should always pay attention to how your body reacts. If something is wrong during your jog or run, the body will certainly let you know by giving you some hints(暗示). Watchfulness can help you avoid all possible aftereffects of over exercise.Every type of sport is special and useful in its own way. While jogging can sometimes bring pain and discomfort, it really offers you greater joy and satisfaction. So don’t step back.20 I hope these tips will help you prepare yourself for jogging and avoid any serious issues.A.Listen to your body signals.B.Never give in to difficulties while joggingC.However, jogging without preparation will bring great harm.D.One of the best ways to prepare is to go to specialized (专门的) shops.E.Just go in for jogging, but remember to follow the above rulesF.Therefore, you should make it a habit to warm up before joggingG.Here are some basic rules to make jogging safe, useful and comfortable三、完形填空(自动售货机).

I didn’t think there would be any patients, sighing about having to work on Christmas. Just then five bodies showed up at my desk, a pale woman and four small children. 3
“Are you all sick?” I asked doubtfully. “Yes,” she said weakly and lowered her head. But when it came to descriptions of their presenting problems, things got a little puzzling. Two of the children had headaches, but the headaches weren’t accompanied by the normal body language of holding the head or trying to keep it still. Two children had earaches, but only one could tell me which ear was affected. The mother complained of a cough but seemed to work to produce it. Something was wrong, but I didn’t say anything but explained that it might be a little while before a doctor saw her.
