17参考答案与解析

参考答案与解析 一、选择题（本大题共7小题，每小题3分，共21分．每小题只有一项符台题意，不选、多选、错选均得0分） 1．“公共场所禁止大声喧哗”，其中“大声“是指声音的（） A．音色B．音调C．响度D．频率 【知识考点】音调、响度与音色的区分． 【思路分析】音调是指声音的高低，响度是指声音的强弱，声音的响度与声源振动的幅度有关，振动幅度越大，响度越大。 【解答过程】解：在公共场所禁止大声喧哗，这里的“大声”是指声音的响度大。 故选：C。 【总结归纳】本题考查了音调和响度、音色的区分，理解各自的含义和特点是正确判断的关键。2．下列几个实例中描述正确的是（） A．夏天，给饮料里加冰块来降温，是利用了冰块熔化放出热量的特点 B．给发烧的病人身上擦酒精降温，是利用了酒精蒸发有致冷作用的特点 C．冬天，北方楼房中的“暖气”用水作介质，是利用水的比热容较小的属性 D．高压锅更容易把食物煮熟，是利用了液体沸点随气压增大而降低的规律 【知识考点】蒸发及其现象． 【思路分析】（1）物质由固态变成液态的现象叫做熔化，熔化吸热； （2）物质由液态变成气态的现象叫汽化，汽化吸热，汽化包括蒸发和沸腾两种方式； （3）相同质量的水和其它物质比较，吸收或放出相同的热量，水的温度升高或降低的少；升高或降低相同的温度，水吸收或放出的热量多； （4）液态沸点与气压有关，气压越大沸点越高。 【解答过程】解：A、给饮料里加冰块来降温，是利用了冰块熔化吸收热量的特点。故A错误； B、用酒精来给高温病人降温，利用了酒精蒸发吸热。故B正确； C、用水来冷却发动机，利用了水的比热容大。根据公式Q=cm△t可知，当物体的质量m和升高的温度△t相同时，物体吸收的热量Q和物质的比热成正比，水的比热容c大，因此利用水吸收的热量多，冷却效果好。故C错误； D、高压锅更容易把食物煮熟，是利用了液体沸点随气压增大而降低的规律。故D错误。 故选：B。 【总结归纳】这样的题目对学生的知识点要求比较高，考查了学生的综合能力。四个选项逐一排查、分析后，才能够得出正确答案。这也是中考的常见题型，难度不大，但是考查的知识面广泛。3．如图所示，下列现象属于光的反射现象的是（） A．B．C．D． 筷子弯折手影海市蜃楼水中倒影 【知识考点】光的反射． 【思路分析】（1）要掌握光的折射现象，知道水底看起来比实际的要浅、斜插入水中的筷子向上折、海市蜃楼、凸透镜成像都是光的折射； （2）要掌握光的反射现象，知道平面镜成像是由于光的反射形成的；

重难点05 概率与统计(解析版)

重难点05 概率与统计 【命题趋势】统计与概率是高考文科中的一个重要的一环高考对概率与统计内容的考查一般以实际应用题出现,这既是这类问题的特点,也符合高考发展的方向.概率应用题侧重于古典概率,近几年的高考有以概率应用题替代传统应用题的趋势,该题出现在解答题第二或第三题的位置，可见概率统计在高考中属于中档题.虽为中档题，但是实际生活背景在加强，阅读量大，所以快速阅读考题并准确理解题意是很重要的.对于这部分，我们还应当重视与传统内容的有机结合. 为了准确地把握2020年高考概率统计命题思想与趋势，在最后的复习中做到有的放矢，提高复习效率，纵观近五年的全国文科I卷，我们看到近几年每年一考,多出现在19题，分值12分；从难度上看：以中档题为主，重基础，考查的重点为统计图表的绘制与分析、数字特征的计算与分析、概率计算、线性回归分析，独立性检验等知识点，一般都会以实际问题为载体，代替传统建模题目.本专题我们把这些热点问题逐一说明，并提出备考指南，希望同学们在复习时抓住重点、事半功倍. 【热点预测以及解题技巧】 热点一：“统计”背景下的“概率”问题 这类问题一般将统计与概率相结合.以频率分布直方图或茎叶图为背景来考查概率知识，有时以表格为背景来考查概率知识，需要从统计图、表格获取信息、处理数据的能力，并根据得出的数据求概率. 热点二：样本分析并通过样本分析作决策 进行样本分析时从统计图表中获取数据，得出频率、平均数、方差，用样本频率估计概率、样本数字特征估计总体数字特征，有时需以此作出决策. 热点三：线性回归分析 根据最小二乘法得出回归直线方程，有时需适当换元转化为线性回归方程. 由于计算量很大，题目一般会给出的参考数据，但是注意数据设置的“障眼法”，这时就要认真领会题意，找出适用的参考数据加以计算. 热点四：独立性检验 寻找数据完成列联表，下面的解题步骤比较固定，按部就班完成即可.

It may or may not be appropriate to talk about primitive peoples or cultures, but that is another matter. Certainly, not all groups of people are equally competent in nuclear physics or psychology or the cultivation of rice or the engraving of Benares brass. But this is not the fault of their language. The Eskimos can speak about snow with a great deal more precision and subtlety than we can in English, but this is not because the Eskimo language (one of those sometimes miscalled ’primitive’) is inherently more precise and subtle than English. This example does not bring to light a defect in English, a show of unexpected ’primitiveness’. The position is simply and obvio usly that the Eskimos and the English live in different environments. The English language would be just as rich in terms for different kinds of snow, presumably, if the environments in which English was habitually used made such distinction important. Similarly, we have no reason to doubt that the Eskimo language could be as precise and subtle on the subject of motor manufacture or cricket if these topics formed part of the Eskimos’ life. For obvious historical reasons, Englishmen in the nineteenth century could not talk about motorcars with the minute discrimination which is possible today: cars were not a part of their culture. But they had a host of terms for horse-drawn vehicles which send us, puzzled, to a historical dictionary when we are reading Scott or Dickens. How many of us could distinguish between a chaise, a landau, a victoria, a brougham, a coupe, a gig, a diligence, a whisky, a calash, a tilbury, a carriole, a phaeton, and a clarence ? 2010年专八真题改错参考答案 1 be后插入as; 2 their改为its; 3 There改为It; 4 Whereas改为But 5 further 改为much 6 come改为bring; 7 similar改为different; 8 will改为would; 9 as important去掉as; 10 the part去掉the 2010年专八真题人文知识参考答案 31、D；32、A；33、D；34、A；35、C；36、D；37、A；38、A；39、C；40、B。 2010年专八真题汉译英参考答案 Friends tend to become more intimated if they have the same interests and temper, they can get along well and keep contacting; otherwise they will separate and end the relationship. Friends who are more familiar and closer can not be too casual and show no respect. Otherwise the harmony and balance will be broken, and the friendship will also be nonexistent any more. Everyone hopes to have his own private space, and if too casual among friends, it is easy to invade this piece of restricted areas, which will lead to the conflict, resulting in alienation. It may be a small matter to be rude to friends; however, it is likely to plant the devastating seeds. The best way to keep the close relationship between friends is to keep contacts with restraint, and do not bother each other. 2010年专八真题英译汉参考答案 我想那是五月的一个周日的早晨；那天是复活节，一个大清早上。我站在自家小屋的门口。就在我的面前展现出了那么一番景色，从我那个位置其实能够尽收眼底，可是梦里的感觉往往如此，由于梦幻的力量，这番景象显得超凡出尘，一派肃穆气象。群山形状相同，其山脚下都有着同样可爱的山谷；不过群山挺然参天，高于阿尔卑斯峰，诸山相距空旷，丰草如茵，林地开阔，错落其间；树篱上的白玫瑰娟娟弥望；远近看不见任何生物，唯有苍翠的教堂庭院里，牛群静静地卧躺在那片郁郁葱葱的墓地歇息，好几头围绕着一个小孩的坟墓。我曾对她一腔柔情，那年夏天是在旭日东升的前一刻，那孩子死去了，我如同当年那样望着牛群。 2010年专八真题作文参考答案 The important role of a city’s local conditions in the urban design Recently there is a hot debate on a report that a foreign design company invited by a little-known mountainous area in Guiyang provided a design without paying too much attention to the city’s unique characteristics. Some people appreciate the bold innovation of the design but others do not like it. In my opinion, any urban design should take the city’s original cultural heritage into account. The designers should suit their design to local conditions and try to take advantage of the local resources.
