A

An Undiscovered Masterpiece

A few years ago, my wife, Sue had some serious health problems. She had suffered surgery after surgery and had also put on weight. Diets had not helped her and she suffered constantly from undiagnosed pain. One day the whole family sat do wn and drew up a “wish list”. To our surprise, one of Sue’s items was to run in a marathon. Given her history and physical limitations, I thought her goal was completely unrealistic, but Sue became committed to it.

She began by running very slowly and every day she ran just a little farther than she did the day before. Soon she could run three miles. Then five. Sue kept practicing and longed to run in the St. George Marathon in southern Utah.

On the big day, I parked our van near the finish line, waiting for Sue. The rain was steady and the wind was cold. The marathon had started over five hours ago. The fast and strong competitors had finished already. Several cold and injured runners had been transported past me, and I began to panic. The image of Sue, alone and cold, off the road somewhere, made me sick with worry. Another hour passed and I spotted a small group running up. As they approached, I could see Sue, in the company of three others, and a woman in her twenties was near Sue. It was obvious that they had become friends during the race. I could see her begin to struggle. But when the finish line came into sight, she confidently even happily picked up her pace the last hundred yards to the finish line. Few people were left to congratulate my wife. T hey openly praised and embraced her, “She made us believe we could do it,” her new friend stated.

From then on, she was carrying herself differently. Her head was more upright. Her shoulders were squared. Her walk had a new confidence. Her voice held a new, quiet dignity. It was not as if she had become someone new; it was more as if she had discovered a real self she had not known before. It was perseverance that made her realize she was an undiscovered masterpiece with a million things left to learn about herself. She truly liked her newly discovered self. So did I.

36. Why did the author think Sue had an unrealistic goal?

A. She was in bad health condition.

B. She occasionally suffered from pains.

C. She was diagnosed with cancer.

D. She always had an unhealthy diet.

37. The author began to panic because ________________.

A. he was cold and lonely on the road

B. he was concerned about Sue

C. he noticed some runners were sick

D. he saw his wife was struggling

38. As for “An Undiscovered Masterpiece”, the author refers to_________.

A. Sue’s squared shoulders

B. the marathon in southern Utah

C. Sue’s newly-discovered self

D. Sue’s newly-made friend

39. The writer wrote this article in order to tell us that _________.

A. Sue did a good job in the marathon

B. Sue made many friends in the race

C. he was grateful because Sue had recovered

D. nothing can take the place of perseverance

Over Half of Young Chinese Block Parents on WeChat Moments We all know the feeling — you want to check what someone you care about has been up to on social media, and suddenly you find you are denied access to their feeds. It’s an instant start of mixed emotions and speculations —when did this happen? Did I do anything wrong? What are they attempting to hide from me?

And that’s what half of Chinese parents have to deal with when they try to browse their children’s WeChat Moments, also known as “Friends’ Circle”, as suggested by a recent survey released by Tencent, the Chinese Internet giant. According to the report, entitled Annual White Paper on Family Affection on WeChat Moments, about 52 percent of WeChat users aged 18 to 29 block their parents on Moments, a major feature on the platform that allows users to share everything they like with their WeChat contacts.

Abo ut 62 percent of the young interviewees said that parents “are neurotic about everything,” along with reasons such as fear of parents’ disapproval, rejection to parents’nagging(唠叨), and seeking privacy. “My parents don’t know Moments very well, so I just told them I don’t use it anymore,” said Qin Jianping, a 28-year-old. He added that his parents had been leaving comments requesting updates on his dating status on every post he made on Moments since he broke up with his girlfriend two years ago. Xie Y un, a 26-year-old, said that while she didn’t block her parents entirely, they were in a specific group to which she only shares positive posts. “I don’t want my parents to see minor setbacks in my life,” she said, adding that once her parents saw a Moments picture of her hand getting slightly burned while cooking, and they traveled all the way to her city to make sure she was all right.

The report also found that more than 49 percent of Chinese parents use WeChat as a main channel to communicate with their children. Roughly 36 percent of the parents who took the survey said they checked every post made by their children. When asked how they would react to being blocked, some parents said they would initiate a conversation with their children to find out the reas on, while others said they wouldn’t care. And some parents just outsmart their kids in this hide-and-seek game online. “I didn’t realize I was blocked until I compared what I could see on my phone to what my son’s aunt could see,” said Chen, a mother of a 27-year-old son. “I chose to remain silent on this and now I’m following my son’s posts through his aunt.”

43. Parents would like to read their children’s WeChat Moments because they _____.

A. are too emotional and speculative

B. want to keep up with the trend of time

C. leave a lot of comments on their feeds

D. are concerned about their children’s lives

44. The children block their parents to______.

A. protect their privacy

B. learn from parents’ nagging

C. challenge parental authority

D. maintain a positive state

45. What can we learn from the last paragraph?

A. Children shouldn’t block their WeChat Moments online.

B. Parents are smart enough to win the “hide-and-seek game”.

C. Parents shouldn’t care about their children’s pr ivate lives.

D. Conversation is the only way for parent-child communication.

46. The author looks into parents’ being blocked is to _______.

A. criticize parents

B. support students

C. analyse a phenomena

D. demand readers

D

New research shows why the emotionally intelligent may earn more money. Many psychologists claimed that EQ, emotional intelligence, really matters in people’s success in life. The question was, however, how much of a benefit EQ could provide in helping people in their life accomplishments.

The related research has found some undetected connections. Miami University of Ohio’s Joseph Rode and colleagues note, “There are few systematic studies of the relationship between EQ and career success.” Recognizin g the need, Rode developed a theoretical model that would account over time for a role of EQ in workplace success. In their model, EQ should be related to the ability to build “social capital” in the form of social support networks. Specifically, people high in EQ should be able to find mentors ----- wise and trusted counselors or teachers who train them in relevant job skills. Possessing these skills, the high-EQ workers should be able to achieve the higher job levels with higher salaries.

A “mental abilities” framework were used, in which they defined EQ as representing a cross between intelligence and emotions. People high in EQ can identify, understand, and regulate their emotions, which allow them to communicate well with others, think about the problems they face, form relationships, and maintain those relationships over time. People with low EQ, by contrast, make constant pains out of themselves and you’ll do all you can to avoid them.

This study are more concerned with the impact of high EQ in social life. People with high EQ are appreciative an d friendly. With a person high in EQ, you’ll go out of your way to be h elpful and supportive, which will make you feel good about yourself and what you’re doing. People high in EQ are so aware of their own needs ---- when they are enjoying helping, they will also reach out for the useful advice and support. What’s more, being good at relationships makes it better for them to form strong bonds with their mentors.

When this theory comes to college, EQ predicted whether participants had obtained work mentors. Those who had mentors also earned more. Going beyond salary, because EQ should be associated with the ability to handle complex relationships, manage stress, and make better decisions, the authors tested a model in which the EQ effect was combined with job level. As it turned out, for people in low job levels, EQ had no impact on salary, but those in higher job levels earned more the higher their EQ scores.

Being high in EQ may not make you rich, of course, but the findings of the Miami University suggest that it will position you better for a path to advancement. Once on that path, fulfillment may mean having

more than a large paycheck, but it is also likely that you’ll gain more emotional pleasure from y our relationships and ability to be successful.

47. Rode and his team developed a model to______.

A. do studies of the relationship between EQ and career success

B. relate EQ to building “social capital” in social support networks

C. find mentors to train people high in EQ throughout social lifes

D. explain the significance of EQ in workplace in the long run

48. The underlined word “mentors” in Paragraph 2 means ________.

A. researchers

B. cooperators

C. instructors

D. colleagues

49. To future college students, the findings in this research ________.

A. seeks emotional pleasure from relationship

B. urges them to get preparation for the career

C. teaches methods of obtaining high salary

D. draws their attention to promoting one’s EQ

50. Which of the following shows the development of ideas in the passage?

A. B. C. D.

I: Introduction P: Point Sp: Sub-point(次要点) C: Conclusion

Neighbors are the people who live near us.They directly affect the social environment we live in. Therefore it is important for us to get closely know our neighbors to feel comfort about our lives. 51 I think there are several qualities that people who live near to us should contain; respectful, helpful and dependable.

To begin with respectful, neighbors should always be respectful and maintain the loyalty between each other and having a good reputation among society. 52 For example, our neighbors should not be noisy because in my family there are many students and they need a quiet atmosphere in order to studying and concent rate on their fields. Moreover they have to avoid of interfering and spying on each other and respect privacy in their lives.

53 For instance, one day I remember a fire was happened in our kitchen. Which that was almost could cause a great dangerous but our next door called the firemen, and also until they arrived to the house they helped us on controlling the fire, which fortunately with their help nothing tragedy happened to our house.

Another aspect of preferable neighbors is to be reliable and trustworthy. 54 And also you may not be worried about any bad events that may happen to you such as if a burglar wants to attempt your house when he found out that you are not at home, the vigilant neighbors immediately call the police and

guide your house not to be stolen.

In conclusion, the these above are vital characteristics of good neighbors. Neighbors will not cause inconvenience to others, be tolerant, cooperatives and dependable in the local community life. 55

A. When will a good neighbor offer his help to you?

B. What are the qualities of a good neighbor in your mind?

C. He won’t teach your children what to do instead of you.

D. In addition, they should be helpful and supportive at any time.

E. Also they should avoid of disturbing and causing too much troubles.

F. You can feel comfort and confidence with these dependable next doors.

G. As a result, neighbors could live cheerfully, happily and harmoniously together.

I am writing to invite you to attend our En glish drama rehearsal and we’d be honored if you could

come and give us a precious guidance.

Our rehearsal is due to be at 2 o’clock this Friday afternoon at the school auditorium, and all the attendants are supposed to be there half an hour earlier. We’re all expecting that you can make it. Since this is the first time for us to hold such an activity, we really lack experience in it. It’s so lucky that you are truly an expert not only in the language but also the performing style of English drama, and thus you can offer us lots of professional and valuable advice.

We really hope you can come and have a good time with us! Many thanks in advance! I am looking forward to your early reply.

四、One possible version

Last week, all the classes were told to give a bulletin board exhibition of our understanding of the traditional Chinese culture.

Having read the notice, we had a heated discussion at the class meeting. Very soon, ideas like Peking Opera, Han Clothing, and Chinese Kung Fu came to us immediately.

With the ideas gathered, we started to prepare for the exhibition. Some of us searched the Internet for more information, while others got down to drawing some pictures about Peking Opera characters and women wearing the Hang clothing. When the designing work was done, we set about working on the bulletin board. We took on different tasks. Besides writing down the main items of the traditional Chinese culture neatly on the board, we also decorated it with beautiful drawings.

2018年全国一卷高考语文模拟试卷Word版含解析

2018年全国一卷高考语文模拟卷 本试卷分第Ⅰ卷(阅读题)和第Ⅱ卷(表达题)两部分。满分150分。考试用时150分钟。 第Ⅰ卷阅读题【70分】 一、现代文阅读(35分) (一)论述类文本阅读(9分,每小题3分) 阅读下面的文字,完成1—3题。 儒家生态伦理思想的现实意义 蔡方鹿 当前,建设生态文明已成为全社会的共识。解决环境污染和生态破坏带来的突出问题,全面提高我国生态文明建设水平,是实现中华民族可持续发展的治本之策。对此,儒家生态伦理思想可提供有益借鉴。 在儒家博大精深的思想体系里,蕴涵着丰富的生态伦理思想。在自然观上,儒家重视人与自然和谐统一,认为人是自然界的一部分、天人是相通的,提倡“天人合一”“仁者以天地万物为一体”,注意保护人类赖以生存的自然环境。这些思想与西方文化强调征服自然、人与自然对立二分的观念形成鲜明对照。 儒家历来反对滥用资源。孔子明确提出“节用而爱人,使民以时”的思想。荀子把对山林川泽的管理、对自然资源的合理开发与保护作为“圣王之制”的内容,要求砍伐和渔猎必须遵守一定的时节,并规定相应的“时禁”期,以保护生物和资源。儒家认为,对待天地万物,应采取友善、爱护的态度;自然资源是人类赖以生存的物质基础,如果随意破坏、浪费资源,就会损害人类自身。孔子说:“伐一木,杀一兽,不以其时,非孝也。”孟子主张把人类之爱施于万物。他说:“亲亲而仁民,仁民而爱物。”朱熹进一步阐发了爱物的思想,他说:“此心爱物,是我之仁;此心要爱物,是我之义。”儒家的生态伦理思想给今天的人们带来有益启示,那就是在发展经济、开发自然、利用资源的同时,必须注意人与自然关系的协调,把发展经济、发展科技与生产力同保护生态环境有机统一起来,把人类生活需要与生态环境运行规律有机结合起来,提高开发自然、利用资源的科学性与合理性。当前,我们解决资源短缺问题,合理利用和有效保护资源,可以借鉴儒家所倡导的取用有节、物尽其用的思想。 今天,生态危机已成为全球性问题。解决这个问题,不仅要在技术层面探索更多治理手段,更重要的是解决人们的思想观念问题。生态危机的实质是文化危机。人类要克服生态危机,继续生存下去并进一步繁荣发展,就必须抛弃以人类为中心、人与自然对立二分的理念,反对盲目强调人是自然的主宰,反对为所欲为地征服和掠夺自然。在这个问题上,儒家主张协调人与自然关系的“天人合一”思想是可资借鉴的理论资源。 当然,儒家生态伦理思想要和当代社会相适应,还需与当代生态伦理学和环保理念结合起来。儒家生态伦理思想包含着诸多超越时空限制的合理内涵,这些符合客观规律的成分不会随时代和地域的变迁而过时;同时,儒家生态伦理思想也存在历史局限性,有一些糟粕。我们要根据当代中国、当今世界发展的实际需要,促进儒家生态伦理思想创造性转化、创新性发展,使之成为生态文明建设的重要思想资源。 (选自《人民日报》,有删改) 1.下列对“儒家生态伦理思想”的表述,不符合原文内容的一项是 A.儒家生态伦理思想提倡“天人合一”“仁者以天地万物为一体”,认为人是自然界的一部分,充分体现了人与自然和谐统一的观点。 B.儒家生态伦理思想给今天社会的发展带来有益的启示,提醒人们在发展经济、开发自然、利用资源的同时,注意人与自然关系的协调等。 C.儒家生态伦理思想把人类生活需要与生态环境运行规律有机结合起来,在当今提高了开发自然、利用资源的科学性与合理性。 D.儒家生态伦理思想包含着许多符合客观规律且不会随时代和地域的变迁而过时的合理内涵,但也存在历史局限性,有一些糟粕。 2.下列理解和分析,不符合原文意思的一项是
