第二部分阅读理解（本大题共两节，每小题2分,共40分）
第一节（共15小题，每小题2分，满分30分）
阅读下列短文，从每题所给的（A,B,C和D）中，选出最佳选项。
A
It's 10:30 pm, and 11-year-old Brandon Blanco is sound asleep at home. Suddenly, a loud noise wakes him up. Naturally, Brandon reaches for his cell phone. The message becomes clear："R U awake？"
Brandon' s use of technology doesn' t stop there. He also has a computer, a TV and three video-game consoles （控制台） in his room. With so many choices, it' s no surprise that when he isn' t at school, he spends nearly every waking minute using one or more of these devices.w w w .x k b Brandon is hardly alone. According to a recent study by the Kaiser Family Foundation, kids aged 8 to18 are spending more time than ever before using electronic devices. How much time？ More than seven and a half hours a day on average, the study found.
The jump is the result of a huge explosion in mobile devices, says Victoria Rideout, the lead author of the study. Today, nearly seven out of ten kids have cell phones. Just five years ago, it was four out of ten.
Often, kids multitask, or use more than one device at a time. " If you’ve got a chance to do something on your computer and take a phone call and have the TV on in the background, why not？" media expert Cheryl Olson says.
Most experts agree technology has much to offer kids. But some worry the kids could be missing out on other activities like playing outside or hanging out with friends. " It' s a matter of balance," says Olson." You’ve got to work on it. "
Multitasking while doing homework is another concern. Some kids listen to music, watch TV or use the phone while doing their homework. "It' s important to make sure that you can stop and concentrate on one thing deeply, " says Rideout.
With new and exciting devices hitting stores every year, keeping technology use in check is more important than ever. " Kids should try," adds Rideout. " But parents might have to step in sometimes. "
21. Why do children spend more time in using electronic devices？
A. Because electronic devices are more exciting than before.
B. Because more electronic devices are available to them.
C. Because they have less other activities.
D. Because they have less homework to do.
22. It is known from the passage that ____.
A. Brandon Blanco feels very annoyed about his late-night text
B. the teenagers using mobile devices have increased by 30% in the past five years
C. most experts think teenagers should not use electronic devices for their studies
D. Cheryl Olson is not surprised about kids' increasing use of mobile devices
23. Which of the following is an example of multitasking according to the passage？
A. Playing video games on the Internet.
B. Talking on the phone while staying with others.
C. Watching TV while using the computer.
D. Listening to music while relaxing.
24. The underlined phrase "in check" in the last paragraph can be replaced by "____".
A. in order
B. in control
C. in store
D. in sight
B
It is quite reasonable to blame traffic jams, the cost of gas and the great speed of modern life, but manners on the road are becoming horrible．Everybody knows that the nicest men would become fierce tigers behind the wheel．It is all right to have a tiger in a cage, but to have one in the driver’s seat is another matter altogether.
Road politeness is not only good manners, but good sense too．It takes the most cool-headed drivers great patience to give up the desire to beat back when forced to face rude driving．On the other hand, a little politeness goes a long way towards reducing the possibility of quarrelling and fighting．A friendly nod or a wave of thanks in answer to an act of politeness helps to create an atmosphere of good will and calm so necessary in modern traffic condition．But such behaviors of politeness are by no means enough．Many drivers nowadays don’t even seem able to recognize politeness when they see it.
However, misplaced politeness can also be dangerous．Typical examples are the driver who waves a child crossing the street at a wrong place into the path of oncoming cars that may be not able to stop in time．The same goes for encouraging old ladies to cross the road wherever and whenever they want to．It always amazes me that the highways are not covered with the dead bodies of these grannies （奶奶）.
An experienced driver, whose manners are faultless, told me it would help if drivers learnt to correctly join in traffic stream without causing total blockages that give rise to unpleasant feelings．Unfortunately, modern drivers can’t even learn to drive．Years ago, experts warned
us that the fast increase of the car ownership would demand more give-and-take from all road users．It is high time for all of us to take this message to heart.
25．According to the passage, troubles on the road are often caused by .
A．road conditions B．the behavior of the drivers
C．the speed of modern life D．the large number of cars
26．In the writer’s opinion, .
A．unskillful drivers should be punished
B．strict traffic rules are badly needed
C．drivers should show road politeness properly
D. drivers should avoid traffic jams
27．The underlined word “give-and-take” in the passage means .
A．politeness and impoliteness
B．good manners and bad manners
C．willingness to give in to each other’s wishes
D．offering help to others as much as possible
28．What is the best title of the passage？
A．Traffic Problems B．Road Politeness
C．Bad Manners on the Road D．Good Drivers and Bad Drivers
C
Climate change，pollution，overuse of water and development are killing some of the world’s most famous rivers including China’s Yangtze．India’s Ganges and Africa’s Nile．WWF said on Tuesday．At the global launch of its report “World’s Top 10 Rivers at Risk”，the group said many rivers could dry out. affecting hundreds of millions of people and killing unique aquatic（水生的）life．
“If these rivers die，millions will lose their livelihoods，biodiversity（生物多样性）will be destroyed on a massive scale，there will be less fresh water and agriculture，resulting in less food security，”said．Rayi Singh，secretary—general of WWF—India．The report,launched ahead of“World Water Day”today，also
cited the Rio Grande in．the United States，the Mekong and Indus in Asia，Europe’s Danube, La Plata in South America and Australia’s Murray—Darling as in need of greater protection．Rivers are the world’s main source of fresh water and WWF says about half of the a vailable supply is already being used up．Dams have destroyed habitats and cut rivers off from their flood plains．while climate change could affect the seasonal water flows that feed them，the report said．Fish populations，the top source of protein and overall life support for hundreds of thousands of communities worldwide，are also being threatened, it found．The Yangtze basin is one of the most polluted rivers in the world because of decades of heavy industrialization，damming and huge influxes（流入）of seaiment（积淀）from land conversion. Climate change，including higher temperatures，also means serious consequences for fishery productivity，water supply and political security in Africa’s arid Nile basin．Tributaries（支流）flowing into the Ganges are drying up because of irrigation，WWF said．
29．We can infer from the text that _____.
A．higher temperatures couldn’t affect fishery productivity
B．rivers’dying out could affect food security
C．there are four Asian rivers mentioned in the passage
D．the Yangtze is polluted thanks to the lack of enough tributaries
30．The top 10 rivers are fast dying as a result of the following EXCEPT _____.
A. climate change B．pollution C．wasting water D．dams
31．WWF is probably a name of _____.
A．a magazine B．a newspaper C．an organization D．a report
D
Twenty years ago, most experts believed that differences in how boys and girls behaved were mainly due to differences in how they were treated by their parents, teachers, and friends. It’s hard to cling to that belief today. Recent research has shown that there are biological differences between boys and girls. Understanding these differences is important in raising and educating children.
For example, girls are born with more sensitive hearing than boys, and the difference increases as kids grow up. So when a grown man speaks to a girl in what he thinks is a normal voice, she may hear it as yelling. Conversely （反过来）, boys who appear to be inattentive in class may just be sitting too far away too hear the teacher.
Likewise, girls are better in their expression of feelings. Studies reveal that negative emotions are seated in an area of the brain called the amygdala. Girls develop all early connection between this area and the cerebral cortex （大脑皮层）, enabling them to talk about their feelings. In boys these links develop later. So if you ask a troubled adolescent boy to tell you what his feelings are, he often cannot say much.
Dr. Sax, an advocate of single-sex education, points out that keeping boys and girls separate in the classroom has yielded striking educational, social, and interpersonal benefits. Therefore,
parents and teachers should try to recognize, understand, and make use of the biological differences that make a girl a girl, and a boy a boy.
32．What is the main idea of the passage？
A. Boys tend to pay less attention in class than girls.
B. Girls are better than boys in their ability to detect sounds.
C. Single-sex schools are not good because they keep boys and girls separate.
D. Boys and girls behave differently because of biological differences.
33．Why do girls express negative feelings better than boys？
A. Girls are more emotional than boys.
B. The links between certain parts of the brain develop earlier in girls than in boys.
C. The amygdala is located in different areas of the brain for boys and girls.
D. Girls have more brain cells than boys.
34．Which of the following does the author believe？
A. Boys and girls should be educated in different ways.
B. Girls need more training in communication.
C. Parents should pay more attention to boys.
D. Sex differences should be ignored in education。
35．What does the phase “cling to” in the first paragraph mean？
A. evaluate
B. abandon
C. maintain
D. challenge

How to Get Prepared for the College Entrance Exams
We are going to attend the College Entrance Exams in less than one year. However, many students still don’t know how to coordinate their study, rest and physical exercise when preparing for the Exams. They usually devote too much time to their study, which results in poor health and low efficiency of learning.
As the proverb goes, early to bed and early to rise makes a man healthy, wealthy and wise. We’d better leave ourselves enough time to sleep since it enables us to learn our lessons more efficiently. What’s more, a strong and healthy body is the base for our further study and our future work and creative activities.
Therefore, as we are preparing for the Exams, don’t forget that rest, exercise and study are equally important.

第二部分：阅读理解（共两节，满分40分） 第一节（共15小题；每小题2分，共30分） 阅读下面短文，从每题所给的A、B、C、D 四个选项中选出最佳答案。 A Some idiomatic phrases in English, often used in both spoken and written language, are very confusing! They don’t even make sense when you first see them. However, using one o f these phrases correctly when speaking or writing to an English speaker is very impressive and shows that you are comfortable with the language. Here are some wonderful and interesting British idioms. Use them wisely. When pigs fly! This expression is one of my favorites and I use it all the time. It is used primarily when speaking, meaning that something is extremely unlikely or impossible. For example, “I will forgive him when pigs fly!” “When do you think you will get a gym membership, Lucy？” “When pigs fly!” A penny for your thoughts？ This question is used in a situation where someone appears thoughtful or is very quiet seeming lost in thought. But remember that you don’t actually have to pay them a penny if they do tell you what is going on! For exampl e, “You’ve been a bit quiet this evening, Pete. A penny for your thoughts？” It’s the bee’s knees The phrase dates back to the 1920s, and refers to an extraordinary person, thing, idea, and so on. For example, “Try this chocolate. It’s the bee’s knees.” To feel a bit under the weather
河南省学年高一语文上学期期中试题 一、现代文阅读（36分） （一）论述类文本阅读（本题共3小题，9分） 阅读下面文字，完成1～3题。 中国绘画发展到了相对成熟的北宋以后，除了民间画家、宫廷画家等创作群体外，还出现了诗人、士大夫等各类文化人参与创作的现象。他们以自身文化人的气质，崇尚和追求唐代诗人兼画家王维作品中所蕴含的“诗中有画，画中有诗”的艺术境界。在绘画创作中，他们以诗人的思考方式，把表现对象提升到诗的艺术境界，创作了很多为后人惯称的“文人画”。 诗人的思考方式，实际上就是中国文人画家基于中国传统画论中东晋大画家顾恺之所言的“迁想妙得”，及后来唐代画家张璪所言的“外师造化，中得心源”的绘画理论，将表现的对象在心中“迁想”成诗的艺术形象的思维过程。中国文人画家的这种诗人的思考方式，是大文化学养背景下成就的结果。诗人和音乐家一样，在感情世界里是最敏感的人群，他们所创作的文人画相较西方画家以科学家的思考方式所表现的科学的艺术形象而言，更接近感情的本质，也更显得纯洁与透明。 中国的文人画家在具体创作中，以顾恺之提出的“传神”的艺术理念为要求，以追求作品的出神入化为最终目的。如宋代画家梁楷所画的《布袋和尚图》和《泼墨仙人图》，以两种粗细不同的艺术手段，表现诙谐而玩世不恭的人物形象。另外，中国文人画家又以诗人的拟人化手段将表现的对象人格化。如明代画家徐渭在《墨葡萄图》中所表现的“笔底明珠无卖处，闲抛闲掷野藤中”。 基于大文化学养背景的文人画家创作的文人画，在具体的画面处理中，比单纯追求形象与色彩变化的西方绘画艺术显得更有广度和深度。他们不仅追求表现对象的“实”处，还以太极中“阴阳”的理念追求其相对“虚”的空间；进而提出了“计白当黑”的画论，将表现的形象延伸到一个更大的审美空间，达到了“此时无声胜有声”的诗意境界。如八大山人的《鱼鸭图卷》、齐白石的《雏鸡》等作品。 中国的文人画家以大文化学养背景铸就了“心旷神怡、超然物外”的冲淡平和的心态，所以在作品中容易叙述心灵的情怀。如宋代米友仁的《潇湘奇观图》表现的“山色空蒙雨亦奇”的境界，元代画家吴镇的《渔父图卷》表现的“斜风细雨不须归”的超然境界。 中国的文人画家在诗、文、书法等各方面的学养上往往都有很高的造诣。中国文人画，那种集诗、书、画于一体的绘画形式，在世界绘画史上是绝无仅有的。文人画不但是中国古

2021届河南省周口市中英文学校2018级高三上学期第一次月考 语文试卷 ★祝考试顺利★ (含答案) 一、现代文阅读(36分) (一)论述类文本阅读(本题共3小题9分) 阅读下面的文字,完成1-3题。 纵观当代对《水浒传》的研究,对其思想认识的主要观点是农民起义、地主阶级内部革新派与保守派之间的斗争、忠奸斗争等,其中农民起义和市井写作的观点是《水浒传》认识的主流。考察北宋时期中国社会结构和商品经济的发展可以看到,除此之外,《水浒传》还表达了新的思想,其核心是夺回被剥夺的人权,要求平等。 《水浒传》从鲁达开始,将对自己的生存价值、尊严的肯定扩展成为对别人不幸命运的普遍同情,在其后出场的众多梁山好汉身上,摆脱个人不幸命运的渴望逐步发展为争取幸福生活的斗争,对弱者贱者一视如我的同情凝聚为对社会正义的向往。 对黑暗现象的揭露在《水浒传》中占有非常重要的地位,对于大量游离出土地和宗法关系的人员,朝廷靠扩军来解决一部分,以至于社会上充斥泼皮和军汉,这些人在书中得以充分反映出来。全书开头即写洪太尉误走妖魔,欺上瞒下,透露着北宋的腐败;特别是只因踢得一脚好球,谜昏君抬举做了殿帅府太尉职事的高俅的出现,将北宋朝廷的昏聩推向高潮。本是浮浪破落户子弟,却加官进爵,自私贪婪,进而公报私仇。迫害王进,致使王进母子夜奔,而后林冲夫妇死别、杨志怀才流落……这样的开头。正如金圣叹所评:“是为揭看掣乱为上作”。这样一个徇私枉法、欺上瞒下的北宋朝廷,怎能不激起英雄的反抗行动。 此外, 《水浒传》中对108好汉排定的座次,制定了严格的制度法规,并颁布号令:“各各管理,悉宜遵守,毋得违忤,有伤意气。如有故违不尊者,定依军法治之,决不轻恕。”梁山的重新社会化过程首先是对个体成员的同化,书中对一些发生在好汉身上的不良行为一开始就表示

He moved there a few years ago, and I was eager to see his new place and meet his friends. My earliest memories of my father are of a tall, handsome, successful man devoted to his work and family, but uncomfortable with his children. As a child I loved him; as a school girl and young adult feared him and felt bitter about him. He seemed unhappy with me unless 1 got straight A's and unhappy with my boyfriends if their fathers were not as "successful" as he was. Whenever I went out with him on weekends, I used to struggle to think up things to say, feeling on guard. On the first day of my visit, we went out with one of my father's friends for lunch at an outdoor cafe. We walked along that afternoon, did some shopping, ate on the street table, and laughed over my son's funny facial expressions. Gone was my father's critical（挑剔的）air and strict rules. Who was this person I knew as my father, who seemed so friendly and interesting to be around？ What had held him back before？ The next day my dad pulled out his childhood pictures and told me quite a few stories about his own childhood. Although our times together became easier over the years, never felt closer to him at that moment. After so many years, I'm at last seeing another side of my father. And in so doing, I'm delighted with my new friend. My dad, in his new home in Arizona, is back to me from where he was. 21. Why did the author feel bitter about her father when she was a young adult？
