The brightest object in the evening sky after the sun and the moon isn't a star, but a planet. It's Venus，our closest neighbor and the second planet from the sun.
Venus is so bright that you can see it both at night and in the early morning. This caused some confusion for ancient Egyptian and Greek star observers. Because they saw Venus at two different times, they thought it was two different planets.
What makes Venus so bright? Huge clouds, 20 miles thick, completely surround it and reflect 75% of the light from the sun that strike them.
For a long time, these clouds caused Venus to be a great mystery to the world's astronomers. If, like other clouds, the ones on Venus were made up of water vapors (水汽），could there not be life hiding beneath them on the planet? Were there “Venusians (金星人)” waiting to communicate with us on Earth?
It was an exciting thought, but on that the Mariner recently landed to rest. The Mariner thoroughly examined Venus and its atmosphere, only to find that the cloud cover was made mostly of deadly carbon dioxide gas. The atmospheric pressure was 15 to 22 times greater than on Earth, which further disproved the theory of life on Venus.
And what did the Mariner find under the clouds? A world of great mountains and smooth areas, dry as a bone. The temperature is about 900°F. That's hot. Although the greatest mystery has been solved, there are still others waiting for us on Venus. Why does Venus rotate (自转）so slowly? What is the inside of Venus like? And most important of all, why is there no water on Venus? If, as it was thought, it was formed about the same time as our planet, it should have water.
These questions and others may some day be answered. Until then, Venus will continue to be the brightest mystery in the sky.
60. Venus is very bright because ________.
A. the clouds surrounding it take in 75% of the sunlight striking them
B. the clouds surrounding it throw back 3/4 of the sunlight striking them
C. 75% of the clouds surrounding it are made up of water vapor
D. 3/4 of the clouds surrounding it are made up of carbon dioxide gas
61. "The Mariner" is probably the name of _______.
A. an astronomer
B. a planet
C. a star
D. a spaceship
62. From the passage we can tell that _________.
A. astronomers still wonder whether Venus is as old as the Earth
B. Venusians are trying to get in touch with us on Earth
C. there are many volcanoes and other natural wonders on Venus
D. whether there is life on V enus is still a question
63. What section of a newspaper is the passage probably taken from?
A. Scientific Technology
B.Science Fictions
C.Brief News
D.Science & Discovery
C
Have you ever heard of Paynes Prairie(大草原)？It is one of the most important natural and historical areas in Florida. Paynes Prairie is located near Gainesville. It is large, 21,000 acres. This protected land is called a reserve, which is managed by the Florida Park Service.
The Paynes Prairie basin was formed when limestone(石灰石）broke down and the ground settled. It is covered by wet prairie plants. There are areas of open water. During brief periods it was flooded enough to be considered a lake. Except for that, the basin has changed little through time.
Man has lived on Paynes Prairie a very long time. He lived there as far back as 10,000 B.C.. At one time, the Seminoles lived there. The prairie is thought to have been named after King Payne, a Seminole chief. During the late 1600s, the largest farm where cattle are fed in Florida was on Paynes.
William Bartram who lived 200 years ago visited Paynes Praire in 1774. Bartram was the first person who described nature through personal experiences as well as scientific observations. At that time he called Paynes Prairie the “great Alachua Savannah". Most of the animal life, which Bartram described, is still here. A large number of animals live here in winter. The variety of animals is increased by the presence of pine flat woods, wetlands and ponds.
The Paynes Prairie Reserve State Park is open all year round. The Florida Park Service works hard so that the park will appear as it did in the past. It offers many opportunities for entertainment. In the park you can camp and picnic. You can hike and bike. You can boat and fish. You can ride on horses. And you can see Florida as it was in the early days.
64. The second paragraph is mainly about _______.
A. how the present Paynes Prairie basin came into being
B. what the present Paynes Prairie basin is covered by
C. why the present Paynes Prairie basin is unchanged

65. All of the following statements are true EXCEPT that _______.
A. the Florida Park Service manages Paynes Prairie
B. you can have fun in the Paynes Prairie Reserve State Park
C. there used to be a big cattle farm on Paynes Prairie
D. William Bartram was the first person to visit Paynes prairie
66. The purpose of the passage is to _______.
A. call on people to protect wildlife of Paynes Prairie
B. introduce Paynes Prairie to people
C. tell people the recorded history of Paynes Prairie
D.attract people to visit Paynes Prairie
67. What will the writer most probably talk about in the paragraph that follows?

C. The natural resources of Florida.
D.The future development of Paynes Prairie.

“Whatever”,totally tops most annoying word in the poll (民意测验).So, you know, it is what it is, but Americans are totally annoyed by the use of “whatever，，in conversations. The
popular term of indifference (不感兴趣)was found most annoying in conversations by 47 percent of the Americans surveyed in a Marist College poll on Wednesday.
“Whatever” easily beat out “you know”, which especially annoyed a quarter of interviewers. The other annoying expressions were "anyway"(at 7 percent), “it is what it is” (11percent) and “at the end of the day”(2 percent).
"Whatever" is an expression with staying power. It left everyone a deep impression in the song by Nirvana (“oh well, whatever, never mind”）in 1991 and was popularized by the Valley Girls in the film “Clueless”, later that decade. It is still commonly used, often by younger people.
It can be a common argument-ender or a signal of indifference. And it can really be annoying. The poll found "whatever" to be consistently(始终地) disliked by Americans regardless of their race, sex, age, income or where they live.
“It doesn't surprise me because …whatever’，is in a special class, probably,said Michael Adams, author of “Slang(俚语)~The People's Poetry" and an associate professor of English at Indiana University. "It's a word that一and it depends on how a speaker uses it一can suggest being not worthy of attention or respect.”Adams, who didn't take part in the poll and is not annoyed by "whatever," points out that its use is not always negative. “It c an also be used in place of other neutral(中性的）phrases that have fallen out of favor, like …six of one, half dozen of the other，” he said. However, he also noted that the negative meaning of the word might explain why “whatever”was judged more annoying than the ever-popular "you know”.
68. Which tops second among the annoying expression according to the passage?'
A. Whatever.
B. You know.
C. Anyway.
D. It is what it is.
69. What can we know about the word "whatever"?
A. It became popular because of Nirvana.
B. It can be commonly used at the beginning of an agreement.
C. Old people like it while young people don't.
D. Almost half of the Americans surveyed disliked it.
70. In Adams' opinion, the reason why “whatever”, was judged more annoying may be that_____.
A. most of the people don't like it
B.it can be used in place of other neutral phrases
C. it carries certain negative meaning sometimes
D. the poor don't like it
71 . Which of the following statements is true?
A. Adams is not only a writer but also a professor.
B. “Whatever” is a signal of concern.
C. Adams is angry at the word “whatever”.
D. "Whatever" will be replaced by "You know”.

Keeping a busy social life among lots of friends may keep people thinner than spending hours doing some exercises, according to scientists. They say that socializing and meeting with friends help increase levels of brown fat in the body which burns calories to produce heat.
Living in an exciting social environment was found to reduce fat in mice's belly by half over four weeks, even if they ate more. US researchers say that social excitement aids weight loss by turning white fat into brown. White fat stores calories and makes us fatter, while brown burns energy to produce heat. Turning white fat into brown is extremely difficult, normally requiring long- term stay in cold conditions or exciting part of the body's nervous system.
However, scientists from Ohio State University now think that having a busy social life is an even more effective way of changing white fat into brown. The team came up with their theory by studying the effects of various living environments on mice. Those, who lived alongside a greater number of mice, had more space and toys to excite themselves and then lost far more weight over the course of the study than their “couch potato" fellows.
Study author, Dr Matthew During, whose team's findings appear in the journal Cell Metabolism, said, "I'm still amazed at the degree of fat loss that occurs." Explaining how new technology had threatened face-to-face socializing, he added, "It's not just a sedentary(久坐的)l ifestyle and high calorie foods, but an increasing lack of social activities." Co-author Dr Lei Cao said，"Loneliness is a potential factor for cancer and death; it's equal to cigarette smoking to a certain extent. Social activities are very vital.
72. What information can we get from the first two paragraphs?
A. Brown fat stores calories and makes us fatter.
B. It doesn't take long to turn white fat into brown.
C. Social excitement helps gain more weight.
D.Brown fat can burn energy to produce heat.
73. Which of the following statement does the text support?
A. Levels of brown fat can be increased by socializing.
B. The mice lacking social life lose more weight.
C. The research findings haven't been published so far.
D. Dr Matthew During wasn't convinced of the result.
74. We can conclude from the text that _______.
A. the fat in mice's belly was reduced because of the relaxing environment
B. a sedentary lifestyle and high calories foods influence people's social life
C. surfing the Internet may influence people's face-to-face communication
D. cancer and death are mainly caused for lack of social life
75. What?s the main idea of the text?
A. Brown fat is beneficial to people's health.
B. Socializing is unnecessarily important in people's daily life.
C. White fat can be changed into brown fat.
D. Socializing contributes to people's losing weight.

参考答案 一、现代文阅读（24分） 1．（3分）A [偷换概念。第1段：“孕育了无数千古流芳的文学巨匠和宗师”，有“文宗在蜀”美誉的不是成都，是整个蜀地。下文李白（一说绵阳）、苏轼（眉山）也有提示作用。] 2．（3分）B[论证方法的作用分析有误。第6段：文中“两宋以文治国，文彦博、宋祁、范成大等名臣先后镇蜀兴办文教”一句是一个论据（先总说，后举例），列举“文彦博”“宋祁”“范成大”等名臣是为了论证两宋时期“学校教育堪称发达”。] 3．（3分）C（A 夸大程度，且以偏概全。第4段：“学徒鳞萃，蜀学比于齐鲁”中“比”是“并列”之意；此外“蜀学”不仅指“求学的人”，更指蜀地的文化成果。B 扩大范围，且强加因果。原文“文翁石室”是中国第一所地方“政府”开办的“公立”学校；文翁亲自教授的是“郡县吏中‘开敏有材者’”。此外文翁招生和授课的方式不构成“蜀中求学蔚然成风”的全部原因。D 张冠李戴。“官学”，是从创办者的身份言之；“府学”则是从行政区划的角度来说的） 4.C（没有表达作者对他们的同情） 5. （6分）①第一次对话的内容是关于豆腐涨价的问题，从女摊主的回答上可以看出夫妻俩不涨价是为了让自己的豆腐更有知名度，说明他们具有商业头脑；（2分）②第二次对话的内容是不愿扩大豆腐坊，要保证豆腐的质量，突出他们讲诚信，重信誉的品质；（2分）③两次对话推动了故事情节的发展，丰富了人物形象，有助于表达小说的主旨。（2分） 6. （6分）①文章的标题“信誉之花”是卖豆腐的夫妻优秀品质的象征，以此为题，表达了对他们的赞美之情；（2分）②全文围绕诚信卖豆腐展开，“信誉之花”是文章的线索；（2分）③“信誉”是社会一个永恒的话题，以“信誉之花”为题，表达了作者对“信誉之花”开满大地的期盼（2分）。 7. C 8. A 9. 问题：①游学机构资质参差不齐。②游学内容注水，游学质量堪忧。③海外游学市场行业门槛低、缺乏标准。措施：①政府出台相关法律法规，对机构资质、服务规范、师资监管等作明确规定。②明确教育、工商和旅游部门的职能范围。③建立游学评价指标体系并定期考核。 【答案】10. A 11. B 12.

福建省莆田第六中学2017-2018学年高一6月月考化学试题B 1. 科学家最近发现两种粒子：第一种是由四个中子构成的粒子，这种粒子称为“四中子”，也有人称之为“零号元素”；第二种是由四个氧原子构成的分子。下列有关这两种粒子的说法正确的是 A. “四中子”的粒子不显电性 B. “四中子”的电子数为4 C. 第二种粒子与O2互为同分异构体 D. 第二种粒子的晶体类型属于原子晶体 【答案】A 【解析】 【详解】A、中子不带电，A正确； B、中子不带电，则“四中子”的电子数为0，B错误； C、O4与O2均是氧元素形成的单质，互为同素异形体，C错误； D、第二种是由四个氧原子构成的分子，形成的是分子晶体，D错误； 答案选A。 2. 下列化学用语表示正确的是: A. CO2分子的球棍模型： B. 14N 的原子结构示意图： C. CH4分子的比例模型： D. 质子数为6,中子数为8 的核素：l4C 【答案】D 【解析】 【详解】A. 球棍模型是用来表现化学分子的三维空间分布。棍代表共价键，球表示构成有机物分子的原子，CO2分子是直线形结构，不是V形分子，A错误； B. 14N的质子数是7，原子结构示意图为，B错误； C. 比例模型是一种与球棍模型类似，用来表现分子三维空间分布的分子模型。球代表原子，球的大小代表原子直径的大小，球和球紧靠在一起，CH4分子的球棍模型为，C错误； D. 质子数为6，中子数为8的核素其质量数是14，可表示为l4C，D正确。 答案选D。
3. 共价键、离子键和分子间作用力是微粒之间的不同作用力，下列物质中含有上述两种作用力的是（） ①NaOH②SiO2 ③NH4Cl ④金刚石⑤NaCl ⑥干冰． A. ①③⑥ B. ①②④ C. ②④⑤ D. ③④⑤ 【答案】A 【解析】 【详解】①NaOH中钠离子与氢氧根之间存在离子键，氢氧之间存在共价键；②SiO2中含有共价键；③NH4Cl中铵根离子和氯离子之间存在离子键，氮氢之间存在共价键；④金刚石中只有共价键；⑤NaCl中只有离子键；⑥干冰中含有共价键，二氧化碳分子间还存在分子间作用力，所以符合条件的是①③⑥。 答案选A。 4. 有5种微粒，它们分别是、、、、，则它们所属元素的种类有 A. 2种 B. 3种 C. 4种 D. 5种 【答案】B 【解析】 【分析】 具有相同核电荷数（即质子数）的同一类原子的总称叫元素；元素符号的左下角表示质子数，左上角表示质量数，质子数相同中子数不同的同一类原子互称同位素，据此分析判断。 【详解】微粒、的质子数相同，所以是同一元素，只是是原子，是离子；、 的质子数相同，所以是同一元素，是原子，是离子；是质子数为18的元素；所以共有3种元素。 答案选B。 【点睛】本题考查了元素的定义，难度不大，注意把握元素概念的外延和内涵，由原子变成离子，变化的是核外电子数，质子数不变。 5. A，B属于短周期元素，能以化学键结合成AB3型的化合物，则AB元素不可能分别属于周期表中的( ) A. ⅠA，ⅦA B. ⅥA，ⅥA C. ⅢA，ⅦA D. ⅤA，ⅠA 【答案】A 【解析】
