That's the finding of an extensive study of Dutch men in which deaths from heart disease were more than 50 percent lower among those who consumed at least an ounce of salt water fish per day than those who never ate fish.The Dutch research is one of three human studies that give strong scientific backing to the long-held belief that eating fish can provide health benefits, particularly to the heart.Heart disease is the number-one killer in the United States, with more than 550,000 death occurring from heart attacks each year. But researchers previously have noticed that the incidence (发病率) of heart disease is lower in cultures that consume more fish than Americans do. There are fewer heart disease deaths, for example, among the Eskimos of Greenland, who consume about 14 ounces of fish a day, and among the Japanese, whose daily fish consumption averages more than 3 ounces.For 20 years, the Dutch study, followed 852 middle-aged men, 20 percent of whom ate no fish. At the start of the study, the average fish consumption was about two-thirds of an ounce each day, with more men eating lean fish (无脂肪鱼) than fatty fish.During the next two decades, 78 of the men died from heart disease. The fewest deaths were among the group who regularly ate fish, even at levels far lower than those of the Japanese or Eskimos. This relationship was true regardless of other factors such as age, high blood pressure, or blood cholesterol (胆固醇) levels.61. Which of the following is NOT true according to the passage?A. The Dutch research has proved that eating fish can help to prevent heart disease.B. Heart doctors won't call your house so long as you keep eating fish each day.C. Among all the diseases heart disease is the most dangerous in America.D There's a low incidence of heart disease in such countries as Japan and Greenland.62. The underlined part "this relationship" refers to the connection between_________and the incidence of heart disease.A. the amount of fish eatenB. regular fish-eatingC. the kind of fish eatenD. people of different regions63. The passage is mainly aboutA. the high incidence of heart disease in some countriesB. the effect of fish eating on people's healthC. the changes in people's diet in recent yearsD. the daily fish consumption of people in different cultures64. Why is heart disease the most dangerous killer in the United States?A. Because American people drink too much spirits.B. Because there are a great many fat people there.C. The author doesn't give a definite answer.D. Because American people eat too much fatty fish.65. How many lives could probably be saved each year in the United States by eating fish according to the Dutch study?A.550,000B.275,000C.110,000D.852CI was in my third year of teaching creative writing at a high school in New York, when one of my students, 15-year-old Mikey, gave me a note from his mother. It explained his absence from class the day before.I had seen Mikey himself writing the note at his desk. Most parental-excuse notes I received were penned by my students. If I were to deal with them, I'd be busy 24 hours a day. The forged excuse notes made a large pile, with writing that ranged from imaginative to crazy. The writers of those notes didn't realize that honest excuse notes were usually dull:“Peter was late because the alarm clock didn't go off."Isn't it remarkable, I thought, how the students complained and said it was hard putting 200 words together on any subject? But when they produced excuse notes, they were brilliant.So one day I typed out a dozen excuse notes and gave them to my classes. I said,“They're supposed to be written by parents, but actually they are not.True, Mikey?" The students looked at me nervously.“Now, this will be the first class to study the art of the excuse note- the first class, ever, to practice writing them. You're so lucky to have a teacher like me who has taken your best writing and turned it into a subject worthy of study.”Everyone smiled as I went on,“You used your imaginations. So try more now. Today I’d like you to write ‘An Excuse Note from Adam to God' or ‘An Excuse Note from Eve to God'.”Heads went down. Pens raced across paper. For the first time ever I saw students so careful in their writing that they had to be asked to go to lunch by their friends.The next day everyone had excuse notes. Heated discussions followed.The headmaster entered the classroom and walked up and down, looking at papers, and then said, “I'd like you to see me in my office."When I stepped into his office, he came to shake my hand and said,“I just want to tell you that that lesson, that task, whatever the hell you were doing, was great. Those kids were writing on the college level. Thank you.”66. What did the author do with the students found dishonest?A. He reported them to the headmaster.B. He lectured them hard on honesty.C. He had them take notes before lunch.D. He helped improve their writing skills.67. The underlined word "forged" in the third paragraph means“_________”.A. formerB. copiedC. falseD. honest68. The author found that compared with the true excuse notes, the produced ones by the students were usuallyA. less imaginativeB. more impressiveC. worse writtenD. less convincing69. The author had the students practice writing excuse notes so the students could learnA. the importance of being honestB. how to write excuse notes skillfullyC. the value of creative writingD. how to be creative in writing70. What did the headmaster think of the author's way of teaching?A. Effective.B. Difficult.C. Misleading.D. Reasonable.DWith child behavior, there is almost much more than it meets the eye. Because it occurs at so many different levels, child behavior that seems simple at one level can often be much more complex and meaningful at another.For instance, a little child's pattern of getting into cupboards, drawers and closed rooms, even after being told not to, is easily considered as bad behavior. When viewed at that level, the pattern is unacceptable and could lead to punishment. But it can be viewed at a more complex and meaningful level, namely child exploration. If a child regularly experiences an angry parent who seems determined to prevent any exploratory activities, the child will decide to continue to achieve future discoveries. When parents view this behavior as born out of natural curiosity rather than simple opposition, they are more likely to accept and appropriately monitor it. Although it may lead to warning responses to ensure the child's safety, it is less likely to lead to punishment.There are countless other examples. Holding a goldfish outside its bowl is foolish at one level but also can be seen as a young child's attempt to express physical affection for a pet. Spending time with friends rather than family is selfish at one level but also indicates a teen's need for independence.The point here is that child behavior is often exhibited in simple forms that can appear to be oppositional, selfish or generally unacceptable if viewed only at that basic level. However,when viewed at more meaningful level, the same apparently simple behavior can be seen as something larger and potentially more adaptive.

He would look up and smile when he saw me and pat the chair next to him for me to sit down. He loved to tell me about his lost golden years when he was an excellent baseball player. I was a good listener. After a couple of hours of talking, I would shake his hands and say goodbye to him. I hopedthat I brought a little sunshine into Walter' s life.I met Walter when I was a high school student participating in a volunteer program with elderly people in a nursing home. It was the first of many such activities, ranging from playing with disabled children to sitting with cancer patients in a hospital. These activities seemed to satisfy my desire to be useful and to feel a meaningful connection to the lives of others.My parents inculcated me with a belief that there was no greater human value than kindness, and encouraged me to make helping others and contributing to society important goals in life. Volunteer work provided a way of attempting to realize the truth of these messages.I learned that volunteerism is not a one-way act of helping someone less fortunate. Involvement in the life of another person has enriched my life as well. Seeing how people deal with the challenges of their lives has taught me valuable lessons in courage and dignity. Many of the people whom I have met as a volunteer are an unforgettable part of my life. Perhaps I received far more than I ever gave.This is why volunteerism works—each of us has so much need for human connection and so much to give to others.91.

6.《唐律疏议·斗讼》“殴伤妻妾”条规定：“诸殴伤妻者，减凡人二等（与凡人比减二等）；死者，以凡人论。殴妾折伤以上，减妻二等”。这一规定，本质上反映了
A. 内阁不具有合法性B. 阁臣对皇权的依附性
C. 中央行政效率低下D. 官僚政治集团的腐朽
【答案】B
【解析】
【详解】李贤作为内阁首辅，所言大都不是主动地进言，而是皇上有所询问则言之，即使有所进谏，亦是帝意所属。结合明代内阁特征，权力来源于皇帝，李贤的做法说明其顺从皇帝的旨意，对皇权有依附性，B正确；题干并不是强调内阁的机构属性，排除A；内阁的出现有助于提高行政效率，但是题干主旨是内阁和皇帝的关系，排除C；D与题无关，排除。
14.俾斯麦执政时期，德国社会保险立法主要有《疾病保险法》《意外事故保险法》《老年和残废保险法》。1910年德国政府将当时所实行的各保险法汇成《工人保险法典》，并在1911年由帝国议会通过。这些立法
A.折射出工业化进程中的社会问题B.体现了德国福利国家初步建成
C.目的在于鼓动民众支持对外战争D.标志着现代社会保障制度确立
10.公元前3世纪左右，富有平民和贵族逐渐融合为新贵，共同把持政权，使罗马从氏族贵族专权的国家变成新的奴隶主贵族专政的国家，以后的平民主要指城乡居民中的下层群众。材料主要说明古罗马
A. 平民阶层已上升为统治阶级B. 帝国统治基础扩大
C 形势发展推动平民内涵变化D. 工商经济发展繁荣
【答案】C
【解析】
【答案】A
【解析】
【详解】材料中的法律都与社会保障有关，是为了解决进入工业社会以后带来的社会问题，所以这些立法折射出的是工业化进程中的社会问题，故选A；材料主要反映了社会保障立法，福利国家的出现是在二战以后，所以更不能据此说明德国建立了现代社会保障制度，排除BD；材料没有反映这些立法的目的，C项内容不能说明，排除。

长歌当哭，是必须在痛定之后的。
而此后几个所谓学者文人的阴险的论调，尤使我觉得悲哀。
我已经出离愤怒了。
我将这非人间的浓黑的悲凉；以我的最大哀痛显示于非人间，使它们快意于我的苦痛，就将这作为后死者的菲薄的祭品，奉献于逝者的灵前。
我已经说过：我向来是以最坏的恶意来推测中国人的。
但这回却很有几点出于我的意外。
（）。
我目睹中国女子的办事，是始于去年的，虽然是少数，但看那干练坚决，百折不回的气概，曾经屋次为之感叹。
至于这一回在弹雨中互相救助，虽殒身不恤的事实.则更足为中国女子的勇毅，虽遭阴谋秘计，压抑至数千年，而终于没有消亡的明证了。
倘要寻求这一次死伤者对于将来的意义，意义就在此罢。
苟活者在淡红的血色中，会依稀看见的希望；真的猛士，将更奋然而前行。

天津市耀华中学2020-2021学年度第一学期期末考试高二年级生物学科试卷1. 下图是外源性过敏原引起哮喘的示意图。
当外源性过敏原首次进入机体后，会使机体产生相应抗体，抗体可吸附在肺组织中肥大细胞的表面，当该过敏原再一次进入机体后，可促使肥大细胞释放出组织胺、白三烯等各种过敏介质。
下列叙述错误的是（）A. 过敏原再次刺激人体，浆细胞会增殖分化分泌抗体B. 组织胺、白三烯对生命活动进行的调节是体液调节C. 临床上可通过药物抑制过敏介质的释放来治疗哮喘D. 过敏原引发的哮喘具有明显的遗传倾向和个体差异【答案】A 【分析】过敏反应是指已经发生免疫的细胞，在相同抗原再次侵入机体时发生的组织损伤或功能紊乱。
根据题意可知，过敏介质主要是组织胺、白三烯等，抑制过敏介质释放可治疗哮喘。
【详解】A、浆细胞属于高度分化的细胞，没有增殖能力，过敏原再次刺激人体时，记忆细胞会增殖与分化，A错误；B、组织胺、白三烯属于化学物质对生命活动进行的调节，因此是体液调节，B正确；C、根据以上分析可知，临床治疗哮喘应该是抑制过敏介质释放，C正确；D、哮喘属于过敏反应，过敏反应的特点是具有明显的遗传倾向和个体差异，D正确。
故选A。
2. 下列有关人体免疫的叙述，正确的有几项（）①引起特异性免疫的抗原都是外来异物②树突状细胞可参与特异性免疫③血浆中溶菌酶的杀菌作用属于人体的第二道防线④病毒抗原和细胞因子均可参与B细胞活化的过程⑤特异性免疫过程中免疫细胞都具有特异性识别抗体的能力⑥预防肺结核的疫苗含有能与结核杆菌特异性结合的抗体A. 二项B. 三项C. 四项D. 五项【答案】B【分析】抗原不都是外来物质，体内异常细胞也能被特异性免疫系统识别；吞噬细胞可以清除被抗体结合后形成的沉淀物或细胞集团；浆细胞只能分泌抗体，没有识别抗原的能力。
【详解】①引起特异性免疫的抗原不都是外来异物，如人体内癌变的细胞也可以作为抗原，①错误；②树突状细胞（DC）可以处理抗原，参与特异性免疫，②正确；③血浆属于体液，体液中的杀菌物质属于第二道防线，③正确；④病毒抗原和细胞因子均可参与B细胞增殖分化的过程，④正确；⑤特异性免疫过程中，吞噬细胞不具有特异性识别抗原的能力，浆细胞不具有识别抗原的能力，⑤错误；⑥预防肺结核的疫苗能促使机体产生相应的抗体，肺结核的疫苗是一种抗原，⑥错误。
