There is a small shop about 200 meters from where I live that sells groceries, meat and other basic necessities. About 10 years ago, there was a beggar who would go into the shop every day and ask the owner for a 36 . The owner, 37 he would lo ve to help, simply didn’t have any jobs available, so he kept 38 the man’s request. https://www.wendangku.net/doc/858498350.html,

第三部分阅读理解（共20小题；每小题2分，满分40分）

第一节：（每小题2分，共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。

A

Scientists in Mexico have just begun a new study of one of the world’s biggest pyramids: the Pyramid of the Sun, north of Mexico City. They’re putting lots of small, high-tech machines under the pyramid to try to unlock some of its secrets. For thousands of years, people have tried to uncover the secrets of the pyramids.

The people who built the pyramids made lots of secret doors and rooms to stop robbers from finding the treasures inside. However, there always have been some smart thieves in history. Now, almost all of Egypt’s pyramids have been robbed, including the Great Pyramid of Khufu, which is the largest pyramid in the world. It is the only one of the ancient wonders of the world that is still standing. https://www.wendangku.net/doc/858498350.html, In AD 820, an Arab king named Abdullah AL Manum got a group of workers to dig their way into the Great Pyramid and have a look. Inside the pyramid, they found three rooms—the Queen’s Chamb er, the Grand Gallery and the King’s Chamber. But to their surprise, the men didn’t find the treasures they wanted. The Queen’s and King’s Chambers were both empty! Where were the King’s mummy and his treasures? Had

someone already taken them away? The hug e stone doors at the pyramid’s entrance were still closed when AL Manum’s men went inside. How had the thieves got in and out?

Since then, many people have gone inside the Great Pyramid to have a look or to try to take things. But still, no other chambers or walkways have been found.

In 2002, an American team made the most recent visit to the Great Pyramid. Scientists sent a robot into the pyramid, but they only found a mysterious locked stone door.

56. The first two paragraphs were written to show that ____.

A. ancient Egyptian emperors were cruel

B. the Pyramid of the Sun is an unusual historic building

C. construction workers led a hard life in ancient Egypt

D. the secrets of the pyramids remain to be uncovered

57. What is the purpose of making some secret doors to the pyramids? _______.

A. To try to unlock some of its secrets

B. To stop robbers from finding the treasures inside

C. To refuse some visitors all over the world into it

D. To tell the truth to the people in the future

58. Which of the following is NOT true to the Great Pyramid of Khufu?

A. It is the largest pyramid in the world.

B. It is the only one of the ancient wonders that is still standing.

C. Abdullah AL Manum took the King’s mummy and his treasures away.

D. Scientists found a mysterious locked stone door to the Great Pyramid.

59. What would be the best title for the text?

A. The Pyramid of the Sun

B. The Great Pyramid of Khufu

C. A Mysterious Locked Stone Door

D. Unlocking the Doors of History of the Pyramid

B

Holidays are really important. Many of us will have childhood memories of summer holidays where we were taken away from home to experience new environments and learn in different https://www.wendangku.net/doc/858498350.html, But holidays are expensive and, for those on low wages or living on benefits, they are often unobtainable. Even the cheapest holidays require travel and other additional costs that are difficult for many

families to meet.

For working parents, the long summer break can be a very difficult problem for childcare. When an annual leave allowance amounts to only five weeks, there is a need to spread this across the year. Couples can find themselves taking leave in turn in order to care for children who are on holiday. For some this makes even an affordable family holiday difficult.

The schools that I visit in Nottingham are full of experienced staff committed to giving our children a caring and inspiring learning environment. The number of children receiving free school meals is quite large in Nottingham and many schools have breakfast clubs to make sure that children get a healthy start to the day. Most schools undertake programs of group or individual educational support. Schools also have an important role in safeguarding children's welfare through the ongoing touch and support with their pupils. During the long summer holidays, much of this is missed.

While teachers are holidaying in the UK, many of their pupils spend the whole six weeks on the street where they live. The lack of free school meals for six weeks can result in pressure on a family budget and an inability to afford the inspiring experiences that help children to continue their https://www.wendangku.net/doc/858498350.html, In setting out its plans for a five-term year, Nottingham City Council (委员会)is seeking to reduce the summer holiday down to four and a half weeks, with a more balanced five terms of roughly eight weeks, each followed by a two-week break. We believe this will give real “down time" for school staff and pupils alike but will be short enough not to cause a real break in learning.

We acknowledge that this change may be difficult for some school staff, particularly whose own children are educated in other authorities. However, this must be weighed against the benefits for city children for whom we all have the greatest duty of care.

60. The passage is probably written by _ .

A. an experienced teacher

B. a working parent

C. an inspired student

D. a city council member

61. The underlined word "they" in the second paragraph refers to " ’.

A. environments

B. holidays

C. wages

D. benefits

62. The plans for a shorter summer holiday will help students______.

A. obtain the cheapest holidays without additional costs

B. get a chance to spend six weeks a term with teachers in school

C. benefit more from the caring and inspiring learning environment

D. have more school days to receive free school meals

63. It can be inferred from the passage that _______.

A. working parents can enjoy a five-week break to care for their children

B. the suggested plans for a five-term school year can hardly be carried out

C. the long summer holiday gives teachers and students real "down time"

D. some school staff will say “ No" to the plans for a shorter summer holiday

C

When I was 17, I read a quote t hat went something like: “If you live each day as if it were your last, someday you’ll most certainly be right.” It made an impression on me, and since then, for the past 33 years, I have looked in the mirror every morning and asked myself, “If today were the last day of my life, would I want to do what I am about to do today?”

Remembering that I’ll be dead soon is the most important tool I’ve ever encountered to help me make the big choice in https://www.wendangku.net/doc/858498350.html,

About a year ago I was diagnosed with cancer. The doctors told me this was almost certainly a type of cancer that was incurable, and that I would live no longer than three to six months. My doctor advised me to go home and get my affairs in order, which is my doctors’ code for preparing yourself to di e.

I lived with that diagnosis all day. I was completely in despair. Later that evening, I had another examination and my wife told me that tumor turned to be curable with surgery. I had the surgery and I’ m fine now.

This was the closest I’ve been to faci ng death. To tell the truth, no one wants to die. And yet death is the destination we all share. No one has ever escaped it. It clears out the old to make room for the new. Right now the new is you, but someday not too long from now, you will gradually become the old and be cleared away.

Your time is so limited that you shouldn’t waste it repeating someone else’s life. Don’ t be trapped by dogma（教条）—which is living with the results of other people’ s thinking. Don’t let the noise of others’ opinions drown out your own inner voice. And most importantly, have the courage to follow your heart. It somehow already knows what you truly want to become. Everything else is secondary.

64. The doctor advised the author to go home and get his affairs in order because ______.

A. he had to rest at home

B. his disease couldn’t be cured

C. his disease was not serious at all

D. he had to wait for the result of the test

65. What does the author think of death?

A. He thinks it is impossible to avoid.

B. He thinks it is not the end of life.

C. He thinks it is nothing to be scared of.

D. He thinks it is the beginning of a new life.

66. In the author’s opinion, we should ______.

A. follow others’ advice

B. take no notice of diseases

C. take exercise and keep healthy

D. have the courage to follow our heart

67. What does the underlined word in paragraph 3 mean?https://www.wendangku.net/doc/858498350.html,

A. came across

B. dealt with

C. survived

D. supported

D

Labor force is defined as being the total number of people who are available to work and earn income. This definition includes everyone who is employed or seeking paid employment, so it includes employers and the self-employed. Labor is one of the country's resources which can be combined with other resources to produce the goods and services wanted by the community.

Although the size of the workforce depends a great deal on the size of the total population, there are several other influences which also affect it. The age distribution (分布) of the total population has a very marked effect on the available workforce. If the population has a high proportion of very young people or of those too old to work, then the available workforce would be lower than if there were a balanced spread age distribution. If the population naturally grows rapidly, the number of births greatly exceeds (超出) the number of deaths then as a total population increases proportion of the workforce declines.

Sometimes a population is described as aging which means that the birth rate is either falling or growing very slowly, and as people retire from the workforce there are insufficient numbers of young people entering it to replace those who are leaving it. In that situation the population is top-heavy with older people. So the percentage of the population in the workforce declines when there is either a rapid increase in births or a falling birth rate.

The age distribution of the population has several important effects on the economy. If the population is aging and there is an increase in the number of people retiring without a corresponding increase in the number entering the workforce, this raises the problem of the ability of the economy to provide a reasonable level of social services to the retired group. If the aged are to be cared for in special homes, finance must be available for that purpose. If the size of the workforce is small relative to the total population, then the government tax revenue (税收) is relatively low and either the government has less money available to it or workforce members have to be taxed more heavily.

68. In the passage “labor force” is defined as ______.

A. people who are available to work and earn income

B. self-employed people who have the ability to work

C. people who are looking for an employment

D. employers who have created job opportunities

69. From the second paragraph we can draw the conclusion that ______.

A. a natural growth of population always leads to a balanced workforce

B. a large population does not necessarily mean a higher proportion of workforce

C. the larger the population is, the higher the proportion of the workforce will be

D. the workforce will be lower if the population has a balanced age distribution

70. When a population is said to be aging，______.

A. there are more people retiring than those entering the workforce

B. the birth rate in the area must be lower than that of death there

C. there should be an oversupply of the workforce members

D. there are more people entering the workforce than those retiring

To forgive is a virtue, but no one has ever said it is easy. When someone has deeply hurt you, it can be extremely difficult to let go of your hate. However, forgiveness is possible, and it can be surprisingly beneficial to your physical and mental health. People who forgive show less sadness, anger and stress and more hopefulness, according to a recent research.

71____ Try the following steps:

Calm yourself. 72 You can take a couple of breaths and think of something that gives you pleasure: a beautiful scene in nature, or someone you https://www.wendangku.net/doc/858498350.html,

Don’t wait for an apology. Many times the person s who hurt you do not intend to apologize. They may have wanted to hurt you or they just don’t see things the same way.73 Keep in mind that forgiveness does not necessarily mean becoming friends again with the person who upset you.

Take the control away from your offender (冒犯者). Rethinking about your hurt gives power to the person who causes you pain. Instead of piling your sad feelings in your heart, learn to look for the love, beauty and kindness around you.

74 ___ If you understand your offender, you may realize that he or she was acting out of unawareness, fear, and even love. You may want to write a letter to yourself from your offender’s point of view.

Don’t forget to forgive yourself. 75 But it can rob you of your self-confidence if you don’t do it.

A.Why should you forgive?

B.How should you start to forgive?

C.Recognize the benefits of forgiveness.

D.Try to see things from your offender’s angle.

E.For some people, forgiving themselves is the biggest challenge.

F.To make your anger die away, try a simple stress-management technique.

G.If you wait for people to apologize, you could be waiting an awfully long time.

第四节：书面表达:

High school is always considered as the most cherished period of one’s life. As a Senior 3 student, it won’t be long before I graduate. Now, I have much to share with my fellow students.

Firstly, I would like to show my appreciation of help from those standing by me all the way, teachers, parents and friends included. Without their help and advice, my life would be different. Secondly, it's high time to say sorry to classmates whom I hurt or misunderstood. Communication and smiles act as bridges to friendship. Above all, I've made up my mind to make every effort to study, for I believe hard work is the key to success. Just as the old saying goes, "No pains, no gains."

Finally I hope that all the younger fellows can make full use of time, because time and tide wait for no men.

【全国百强校】河北省衡水中学2018届高三十六模理综生物试题(解析版)

河北省衡水中学2018届高三十六模理综 生物试题 一、选择题 1. 下列关于细胞内含磷化合物的叙述，错误的是 A. 为生命活动直接供能的“通货”是含磷化合物 B. 对细胞代谢具有催化作用的酶都是含磷化合物 C. 组成细胞膜、核糖体、染色体都有含磷化合物 D. 人体维持内环境pH的稳定有含磷化合物参与 【答案】B 【解析】为生命活动直接供能的“通货”是ATP，为含磷化合物，A正确；对细胞代谢具有催化作用的酶，大多数是蛋白质，少数是RNA，其中蛋白质不一定含有磷，B错误；组成细胞膜的磷脂分子、组成核糖体的RNA、组成染色体的DNA都是含磷化合物，C正确；人体维持内环境pH的稳定有含磷化合物参与，如缓冲物质磷酸氢二钠和磷酸二氢钠，D正确。 2. 下列有关细胞内物质含量比值的关系，正确的是 A. 细胞内结合水/自由水的比值，种子萌发时比休眠时高 B. 人体细胞内02/C02的比值，线粒体内比细胞质基质高 C. 神经纤维膜内K+/Na+的比值，动作电位时比静息电位时高 D. 适宜条件下光合作用过程中C5/C3的比值，停止供应C02后比停止前的高 【答案】D 【解析】种子萌发时细胞代谢旺盛，自由水含量多，细胞内结合水/自由水的比值比休眠时低，A错误；人体细胞在进行有氧呼吸时，每分解1摩尔的葡萄糖，则在线粒体基质中产生6摩尔的CO2，在线粒体内膜上消耗6摩尔的O2，人体细胞在进行无氧呼吸时，既无CO2的产生有无O2的消耗，B错误；神经细胞内K+浓度明显高于膜外，而Na+浓度比膜外低，静息电位的产生与维持主要是由于K+外流，动作电位产生的机制是Na+内流，所以K+/Na+的比值，动作电位时比静息电位时低，C错误；光合作用的暗反应阶段，首先发生CO2的固定，即CO2与C1化合物结合生成C2，随后在光反应产生的ATP提供能量的前提下，C2被光反应的产物[H]还原，所以适宜条件下光合作用过程中C1/C2的比值，停止供应CO2后比停止前的高，D正确。 【考点定位】细胞代谢 3. 科技工作者在广西发现了可能是现代栽培水稻祖先的万年野生稻，它们不但抗病、抗虫害能力特别强，一穗可达千粒果实，而且可与近缘栽培水稻杂交产生可育子代，以提高栽培水稻的抗逆性和产量。下列叙

河北省衡水中学2018届高三年级七调考试【答案打印版】

河北省衡水中学2018届高三上学期七调考试 语文试题参考答案 2018年3月30日1．B（A．“这说明审美价值重于实用价值”。原文句子“中国的陶瓷闻名遐迩，丝绸远销世界，古代建筑令人陶醉，皆因实用价值与审美价值相得益彰。”C．错在“说到底就是为了增强科技产品的竞争力”。原文说“凝聚着美……给人更多便利感受和美的体验”。D．错在“多些技术的诗意，实质正是遵守技术伦理，把创意和人文有机融合。”偷换概念。）2．B（错在“是为了说明人文要素比效率、性能更重要”。两者之间是相得益彰，互不缺少的关系。缺少“效率、性能”的科技，没有使用价值。而缺少“人文要素”的科技创新美感。） 3．A（错在此句表述本身就是错误。“某些技术成果缺少良好的用户体验的根本原因在于设计者在“贪多求快的浮躁心理驱使下主动放弃了对诗意的探求”。） 4．A（牧羊人对“我”的怀疑和不相信，是因为汉人疯狂采伐石头，不仅对当地地貌造成不可逆转的破坏，也对当地游牧民族人们的价值观带来了冲击，起了贪念的是疯狂采伐石头的汉人。） 5．答案：①人类疯狂开采石头，对戈壁滩的地貌造成了极大的伤害，但所开采的石头制作成商品后在城市售卖，价格却十分廉价。②人类因贪婪对大自然造成了不可逆转的伤害，这种伤害让人感到“哀凉无望”。③现代文明对游牧文明的价值观带来了冲击。（第一、二点，每点2分，第三点1分。） 6．答案：因为“我”深深认识到： ①“我”虽然喜爱石头，但不能把“喜爱”变成“贪婪”而去占有不属于自己的石头； ②触碰石头不仅会改变一只虫子的命运，甚至可能会改变更多——季节、气候、降雪量等，从而造成各种自然灾害。 ③戈壁玉的确美丽，但一旦离开荒野，离开纯粹的蓝天和粗砾的大地，它的美丽便迅速枯萎（每点2分。） 7．A（本题考查文本内容的理解分析。本题要求找出不属于该书观点的一项。题中A 错在遗漏信息，林风眠被誉为“百年巨匠”之一的原因很多，“奠定了中国现代绘画的基础”和“培养了很多大师级的名家”等也不可忽视。） 8．B、E（本题重点考查学生把握文章内容和筛选文章信息的能力。找到答题区间，筛选关键词句，概括形成答案。A．林风眠从小接受了良好的教育，既在学校接受了系统的文化学习，又在梁伯聪、南洋回来的朋友等人的影响下关注西方的艺术世界，这为他日后进行中西调和的创新打下了基础。C．为接受了“西方现代艺术和思想的双重启蒙”，中国传统艺术的启蒙他幼时就接受了。D．无中生有，林风眠出国留学、在国外艺术展上一举成名并未提到他的爱国情怀。） 9．①保持好奇心，善于学习。无论是中国的传统艺术、西洋插画，还是西方的艺术理论与思想，林风眠都兼收并蓄。 ②善于创新，能打破传统。林风眠不一味地做守规矩的“好学生”，才能在复兴东方岂术和调和东西艺术方面走出了一条自己的路。 ③贴近生活，保持人味。他的画作直接描述生活，拷问人性，富有活力。 ④耐住寂寞，专心创作。林风眠在上海不问世事埋头作画，最终让自己的艺术达到前所未有的高度。 ⑤有师友亲人的帮助。梁伯聪将林风眠引向了艺术的新天地，蔡元培的任人唯贤，父亲的影响，等等，都促成了林风眠的成功。 10．C（抓住关键主语“帝”“言官”和关键词“使”“再”。） 11．D（“汉武帝”是谥号。谥法制度有两个要点：一是谥号要符合死者的为人，二是谥号在死后由别人评定并授予。君主的谥号由礼官确定，由即位皇帝宣布，大臣的谥号是朝廷赐予的。谥号带有评判性，相当于盖棺定论。） 12．B（“余懋衡和王基洪等御史官先后把这件事上奏皇帝弹劾梁永”与文中内容不符。由原文“永虑军民为难，召亡命擐甲自卫。御史王基洪声言永必反，具陈永斩关及杀掠吏民状。巡抚顾其志颇为永讳，永乃藉口辨。帝疑御史言不实。”可以推测。）

I’ve decided to lose weight and I had to give up cakes. It’s difficult because I have a sweet tooth and I love cream cakes. Not having treats can be good for your health. I’ve heard that the Burts, a family of five in South East England，lived sugar free for a whole year after they found out their daughter had diabetes (糖尿病).It wasn’t easy. To avoid temptation, I don’t go to any bakeries, but this family actually owns one, which makes up to 3 ,000 cakes a week. They were in shock when the doctor said that their 16-year-old Lucy had to check her blood sugar levels regularly and take insulin (胰岛素). He advised her to eat a normal,balanced diet,but the Burts went further and got rid of sugar altogether.

上海市嘉定区2019届高三英语一模

考试六大应试技巧 一、自我暗示、消除焦虑 ①自我暗示法。用平时自己考试中曾有优异成绩来不断暗示自己：我是考生中的佼佼者；我一 定能考得理想的成绩；我虽然有困难的题目，但别人不会做的题目也很多。 ②决战决胜法。视考场为考试的大敌，用过去因怯场而失败的教训鞭策自己决战决胜。 二、整体浏览，了解卷情 拿到试卷后，在规定的地方写好姓名和准考证号后，先对试卷进行整体感知，看看这份试卷共 多少页、总题量是多少、分哪几大部分、有哪几种题型。这样不仅可以要防止试卷错误，尽早调换， 避免不必要的损失；而且通过对全卷作的整体把握，能尽早定下作战方案。重要的是初步了解下试 卷的难易度，以便自己合理安排答题时间，避免会做的没有做，不会做的却浪费了时间的情况出现。 三、“两先两后”，合理安排 ①先易后难 ②先熟后生 四、“一慢一快”，慢中求快 一、书写速度应快，不慢慢吞吞。二、书写的内容要简明扼要，不拖泥带水，噜嗦重复，尽量 写出得分点就行了。 五、分段得分，每分必争 对于会做的题目。对会做的题目要解决对而不全的老大难问题，如果出现跳步往往就会造成丢 分的情况，因此，答题过程一定规范，重要步骤不可遗漏，这就是分段得分。 对于不会做的题目，这里又分两种情况，一种是一大题分几小题的，一种是一大题只有一问的。 对于前者，我们的策略是“跳步解答”，第一小题答不出来，就把第一小题作为已知条件，用来解答 第二小题，只要答得对，第二小题照样得分。对于后者，我们的策略是“缺步解题”，能演算到什么程度就什么程度，不强求结论。这样可以最大程度地得到分数。 六、重视检查环节 如果自己的考试时间还有些充裕，那么根不可匆忙交卷，而应作耐心的复查。将模棱两可的及 未做的题目最后要进行检查、作答，特别是填空题、选择题不要留空白。
