My color television has given me nothing but a headache. I was able to buy it a little over a year ago because I had my relatives give me money for my birthday instead of a lot of clothes that wouldn’t fit .I let a salesclerk fool me into buying a discontinued model, I realized this a day later, when I saw newspaper advertisements for the set at seventy-five dollars less than I had paid, The set worked so beautifully when I first got it home that I would keep it on until stations signed off for the night, Fortunately, I didn’t got any channels showing all -night movies or I would never have gotten to bed.
Then I started developing a problem with the set that involved static (静电) noise. For some reason, when certain shows switched into a commercial, a loud noise would sound for a few seconds. Gradually, this noise began to appear during a show, and to get rid of it, I had to change to another channel and then change it back. Sometimes this technique would not work, and I had to pick up the set and shake it to remove the sound. I actually began to build up my arm muscles(肌肉) shaking my set.
When neither of these methods removed the static noise ,I would sit helplessly and wait for the noise to go away. At last I ended up hitting the set with my fist, and it stopped working altogether .My trip to the repair shop cost me $62, and the set is working well now, but I keep expecting more trouble.
1．Why did the author say he was fooled into buying the TV set? A. He got an older model than he had expected. B. He couldn’t return it when it was broken. C. He could have bought it at a lower price. D. He failed to find any movie shows on it.
2．Which of the following can best replace the phrase ”signed off” in Paragraph 1? A. ended all their programs B. provided fewer channels C. changed to commercials D. showed all-night movies 3．How did the author finally get his TV set working again? A. By shaking and hitting it. B. By turning it on and off.
○………○………4．How does the author sound when telling the story ? A. Curious B. Anxious C. Cautious D. Humorous
Your house may have an effect on your figure. Experts say the way you design your home could play a role in whether you pack on the pounds or keep them off. You can make your environment work for you instead of against you. Here are some ways to turn your home into part of your diet plan.
Open the curtains and turn up the lights. Dark environments are more likely to encourage overeating, for people are often less self-conscious (难为情) when they’re in poorly lit
places —and so more likely to eat lots of food. If your home doesn’t have enough window light, get more lamps and flood the place with brightness.
Mind the colors. Research suggests warm colors fuel our appetites. In one study, people who ate meals in a blue room consumed 33 percent less than those in a yellow or red room. Warm colors like yellow make food appear more appetizing, while cold colors make us feel less hun gry. So when it’s time to repaint, go blue.
Don’t forget the clock—or the radio. People who eat slowly tend to consume about 70 fewer calories (卡路里) per meal than those who rush through their meals. Begin keeping track of the time, and try to make dinner last at least 30 minutes. And while you’re at it, actually sit down to eat. If you need some help slowing down, turn on relaxing music. It makes you less likely to rush through a meal.
Downsize the dishes. Big serving bowls and plates can easily make us fat. We eat about 22 percent more when using a 12-inch plate instead of a 10-inch plate. When we choose a large
spoon over a smaller one, total intake (摄入) jumps by 14 percent. And we’ll pour about 30 percent more liquid into a short, wide glass than a tall, skinny glass.
5．The text is especially helpful for those who care about ____________. A. their home comforts B. their body shape C. house buying D. healthy diets
6．A home environment in blue can help people ______________. A. digest food better B. reduce food intake C. burn more calories D. regain their appetites 7．What are people advised to do at mealtimes? A. Eat quickly. B. Play fast music.
C. Use smaller spoons.
D. Turn down the lights. 8．What can be a suitable title for the text?
A. Is Your House Making You Fat?
B. Ways of Serving Dinner
C. Effects of Self-Consciousness
D. Is Your Home Environment Relaxing?
More student than ever before are taking a gap-year (间隔年)before going to university.It used to be called the “year off” between school and university.The gap-year phenomenon originated(起源) with the months left over to Oxbridge applicants between entrance exams in November and the start of the next academic year.

A student walks into his first class and realizes he forgot all about the midterm exam. He knows he needs to bring his grades up, and getting a zero will make it nearly impossible. He quickly jots down some notes and shoves them under his lap hoping it will help him pass. Cheating is a major concern in all academic environments. Students are creating new and more outrageous(令人吃惊的）ways of cheating every day: some claim that certain accounts of cheating can be justified, but overall it can always be prevented.
Cheating has been around forever, and millions of ways to cheat have been fashioned. Copying homework and cheat sheets are some of the most basic ways students in all education levels have cheated. Some students think nothing about writing a few answers on their hand, in a gum wrapper, or boldly using a study guide to cheat. Desperate students have even gone as far as to steal the test or scan in bottle wrappers and put answers into the nutrition label. The internet has now become available in almost every location. Computers can be accessed at school, at home, and now even on cell phones. This opens a doorway for even more methods of cheating to be born.
There are countless opinions on whether or not cheating can be justified. The
truth is this behavior will always be a matter of opinion with each scenario of
It may be difficult to accomplish, hut cheating can be prevented. 1'eachers and professors have tried many options to stop cheating. These options can range anywhere from simply spreading test-takers out in a room, to expelling（驱逐）a student, which will most likely hinder their plans of getting into another college. One simple way to fix the problem is to scold the student when caught. They may be so scared or embarrassed that they never do it again. This is a risky way to prevent cheating in some cases, however, because it can possibly damage self-esteem. Another simple way 10avoid cheating is to create many different kinds of the same test. This prohibits students from getting the answers off of a neighbor's test, but students still have the option of
using other cheating tactics.
16．Which is the best title of this passage?
A. To cheat or not to cheat
B. Show your opinion on cheating
C. Debates on cheating
D. Different ways of cheating
17．The second paragraph mainly tells us that.
A. cheating through the Interne t is the most basic way
B. students who cheat in exams are cleverer
C. millions of ways to cheat have been fashioned
D. students cheat in exams to score better grades

A. they don't understand their teachers' words
B. they bury themselves in a lot of homework
C. they don't have enough time to complete the study tasks
D. they forget to look over the material
19．What is the disadvantage of scolding the cheating students according to the passage?
A. They may continue to cheat next time.
B. They may be hurt mentally.
C. They may use other cheating tactics.
20．What is the author's attitude towards cheating? A. It is reasonable B. It is necessary C. it can be praised D. It must be prevented 二、七选五

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。）
