上海市徐汇中学2018-2019学年高一物理下学期期中试题 一、单项选择题 1.匀速圆周运动是一种( ) A. 匀速运动 B. 匀加速运动 C. 匀加速曲线运动 D. 变加速曲线运动 【答案】D 【解析】 匀速圆周运动加速度始终指向圆心，方向时刻在变化，加速度是变化的，是变加速曲线运动，故D 正确，ABC 错误。 2.由于地球自转，地球表面上的物体都随地球一起作匀速圆周运动，将地球视为球体，如图所示， a 、b 两处物体运动的（ ） A. 线速度相同 B. 角速度相同 C. 线速度不同，且v a ＞v b D. 角速度不同，且 a ＜ b 【答案】B 【解析】 a 、 b 两处物体随地球自转一起作匀速圆周运动，则a b ωω=，又因为两者转动的半径a b r r <，据v r ω=可得：a b v v <。 故B 项正确。 点睛：同轴传动：被动轮和主动轮的中心在同一根转轴上，主动轮转动使轴转动进而带动从动轮转动，两轮等转速及角速度。皮带传动：两转轮在同一平面上，皮带绷紧与两轮相切，主动轮转动使皮带动进而使从动轮转动，两轮边缘线速度相等。
3.匀速圆周运动中，线速度v 、角速度ω、周期T 、半径R 之间的关系，正确的是（ ） A. ω=vR B. ω=2πT C. v =ωR D. 1 T ω = 【答案】C 【解析】 【详解】根据角速度定义： 2t T θ πω= = 线速度定义： 2s R v t T π= = 可知： v R ω= v R ω= 2T π ω = A ．ω=vR ，与分析不符，故A 错误； B ．ω=2πT ，与分析不符，故B 错误； C ．v =ωR ，与分析相符，故C 正确； D ．1 T ω =，与分析不符，故D 错误。 4.如图所示，弹簧振子在B 、C 两点间做无摩擦的往复运动，O 是振子的平衡位置．则振子( ) A. 从B 向O 运动过程中速度一直变小 B. 从O 向C 运动过程中速度一直变小 C. 从B 经过O 向C 运动过程中速度一直变小 D. 从C 经过O 向B 运动过程中速度一直变小 【答案】B 【解析】

英语期中考试试卷 Part I Reading Comprehension (10×4 = 40) Passage One Television has opened windows in everybody's life. Young men will never again go to war as they did in 1914. Millions of people now have seen the effects of a battle. And the result has been a general dislike of war, and perhaps more interest in helping those who suffer from all the terrible things that have been shown on the screen. Television has also changed politics. The most distant areas can now follow state affairs, see and her the politicians before tan election. Better informed, people are more likely to vote, and so to make their opinion count. Unfortunately, television's influence has been extremely harmful to the young. Children do not have enough experience to realize that TV shows present an unreal world; that TV advertisements lie to sell products that are sometimes bad or useless. They believe that the violence they see is normal and acceptable. All educators agree that the "television generations" are more violent than their parents and grandparents. Also, the young are less patient. Used to TV shows, where everything is quick and interesting, they do not have the patience to read an article without pictures; to read a book that requires thinking; to listen to a teacher who doesn't do funny things like the people on children's programs. And they expect all problems to be solved happily in ten, fifteen, or thirty minutes. That's the time it takes on the screen. 1. In the past, many young people ______. A) knew the effects of war B) went in for politics C) liked to save the wounded in wars D) were willing to be soldiers 2. Now with TV people can ________. A) discuss politics at an information center B) show more interest in politics C) make their own decisions on political affairs D) express their opinions freely 3. The author thinks that TV advertisements ______. A) are not reliable on the whole B) are useless to people C) are a good guide to adults D) are very harmful to the young 4. Which is NOT true according to the passage? A) People have become used to crimes now. B) With a TV set some problems can be solved quickly. C) People now like to read books with pictures. D) The adults are less violent than the young. 5. From the passage, we can conclude that _______. A) children should keep away from TV B) TV programs should be improved C) children's books should have pictures D) TV has a deep influence on the young Passage Two Many a young person tells me he wants to be a writer. I always encourage such people but I also explain that there's a big difference between "being a writer" and " writing". In most cases these individuals are dreaming of wealth and fame, not the long hour alone at a typewriter. "You've got to want to write," I say to them, "not want to be a writer". The reality is that writing is a lonely, private and poor-paying affair. For every writer killed by fortune there are thousands more whose longing is never rewarded. When I left a 20-year career in
湖南省长沙市长郡中学2019-2020学年高一数学上学期期中试题（含 解析） 一、选择题：本大题共15个小题，每小题3分，共45分，在每个小题给出的四个选项中，只有一项是符合题目要求的． 1.已知集合{}12A x x =-<<，{}220B x x x =-<，则A B =（ ） A. ()10 -， B. ()02， C. ()20-， D. ()22-， 【答案】B 【解析】 【分析】 解一元二次不等式求得集合B ，由此求得A B . 【详解】由()2220x x x x -=-<，解得02x <<，所以()0,2A B =. 故选：B. 【点睛】本小题主要考查集合交集的概念和运算，考查一元二次不等式的解法，属于基础题. 2.函数() f x =的定义域为（ ） A. (]30-， B. ()31-， C. ()3-∞-， D. ()(]331-∞--，， 【答案】A 【解析】 【分析】 根据偶次方根的被开方数为非负数，分式分母不为零列不等式组，解不等式组求得函数的定义域. 【详解】依题意，12030 x x ?-≥?+>?，解得30x -<≤. 故选：A. 【点睛】本小题主要考查函数定义域的求法，主要是偶次方根的被开方数为非负数，分式分母不为零，属于基础题.
3.若函数f （x ）＝()()()211 1a x x ax x ?-≥??+，即2a <；由1x <时，()1f x ax =+是增函数，得0a >；又()f x 的定义域为R ，所以在1x =应有12+≤-a a ，即12a ≤，综上，实数a 的取值范围是1(0,]2 ，故选C. 【点睛】本题主要考查分段函数的单调性,容易忽略对分界点左右两边的函数值大小关系进行讨论. 4.下列函数既是偶函数，又在（0，+∞）上为增函数的是（ ） A. y x = B. y ＝2x - C. y ＝|x| D. 1y x = 【答案】C 【解析】 【分析】 逐一判断每个函数的奇偶性和单调性，可得正确答案. 【详解】对于A ， y x =，为奇函数，不符合题意；对于B ，2y x =-，为偶函数，在(0,)+∞上单调递减，不符合题意；对于C ， y x =，既是偶函数，又在(0,)+∞上单调递增，符合题意；对于D ，1 y x =，为奇函数，不符合题意；故选C. 【点睛】本题主要考查常见函数的单调性和奇偶性的判断，较基础.
