吉林省吉林市 普通中学2013届高三高考模拟理综 物理试题(物理,解析版)
吉林省吉林市普通中学2013届高三上学期毕业班摸底物理试题(解析版)第I 卷(选择题 共48分)本卷共12小题,每小题给出的四个选项中,有的只有一个选项正确,有的有多个选项正确,全选对的得4分,选对但不全得2分,有选错或不答的得0分,将你的答案填写在“答题纸”对应的题号处。
1.根据牛顿第二定律,下列叙述正确的是A.物体加速度的大小跟它的质量和速度大小的乘积成反比B.物体所受合外力必须达到一定值时,才能使物体产生加速度C.物体加速度的大小跟它的所受作用力中的任一个的大小成正比D.当物体质量改变但其所受合力的水平分力不变时,物体水平加速度大小与其质量成反比2.a 、b 两物体从同一位置沿同一直线运动,它们的速度图象如图所示,下列说法正确的是A .a 、b 加速时,物体a 的加速度大于物体b 的加速度B .60秒时,物体a 在物体b 的前方C .20秒时,a 、b 两物体相距最远D .40秒时,a 、b 两物体速度相等,相距200m答案:B 解析:a 、b 两物体同地同一直线运动,从速度图象看速度都为正值,即同向行驶.a的加速度a=t v ∆∆=1.5 m/s 2,b 的加速度a′=t v '∆'∆=2 m/s 2.,所以a 物体的加速度小于b 物体的加速度,即A 项错误。
.20 s 时,a 物体速度达到v=40 m/s 而b 物体仍静止,只有当40 s 时,即a 、b 两物体的速度相等时,a 、b 两物体才相距最远,此时相距的距离为Δs=(800 m+500 m)-400 m=900 m,.所以CD 项错误。
当60 s 时a 的位移为s a =21×(10+40)×20 m+40×40 m=2 100 m..。
而b 的位移s b =21×40×100 m=2 000 m,所以a 在b 的前方即B 项正确.3.一根轻质弹簧一端固定,用大小为1F 的力压弹簧的另一端,平衡时长度为1l ;改用大小为2F 的力拉弹簧,平衡时长度为2l 。

17.AB
[解析:质点做直线运动,其所受电场力和重力的合力必沿直线方向,如图。当F=mgsinα时,F一定与物体运动方

oncoming freight trainTwenty-five people including Sanchez died and more than 130 got hurt in the crash Sanchez was sending text messages from his mobile phone that day and some teenagers told a local news station they received one such message from him one minute before the crashThe California Public Utilities Commission which manages transportation in the state has now banned rail employees from using mobile phones while working on a moving train If they do so they could face a fine of up to 20000 The measure strengthens an existing ban issued by the train companyThere was another crash in

moving trainBWhen were young and we dream of love and fulfillment we think perhaps of moon-covered Parisian nights or walks along the beach at sunset No one tells us that the greatest moments of a lifetime are short unplanned and nearly always catch us off guardNot long agoas I was reading a bedtime story to my seven-year-olddaughter Annie I became aware of her focused look She was staring at me with a faraway blank expression Apparently completing The Tale of Samuel Whiskers was not as important as we first thoughtI asked what she was thinking about"Mommy" she whispered "I just cant stop looking at your pretty face"I almost dissolved on the spotLittle did she know how many trying moments the glow of her sincerely loving statement would carry me through over the following years Not long after I took my four-year-old son to an elegant department store where the sweet notes of a classic love song drew us toward a tuxedoed 穿晚礼服的 musician playing a grand piano Sam and I sat down on a marble bench nearby and he seemed as astonished by the pleasant theme as I wasI didnt realize that Sam had stood up next to me until he turned took my face in his little hands and said "Dance with me"If only those women walking under the Paris moon knew the joy of such an invitation made by a round-cheeked boy with baby teeth Although shoppers openly chuckled 咯咯笑 and pointed at us as we glided and whirled around the open space I would not have traded a dance with sucha charming young gentleman if Id been offered the universe60 From the passage we know____A Annie knew how important she was

To the publishers surprise every one of her books was sold The publisher realized womens stories were interesting and agreed to publish all her other novelsJane Austen completed six books altogether and all of them are still being read today In the last few years several of her novels have been made into films including Sense and Sensibility the novel which she had to publish by herselfDuring

2013年高考5吉林省实验中学高三第二次模拟考试
2013年高考(445)吉林省实验中学高三第二次模拟考试吉林省实验中学2013年高三年级下学期第二次模拟考试题语文试题第卷阅读题甲必考题一、现代文阅读(9分,每小题3分)阅读下面的文字,完成1~3题。
谈人朱光潜世间事物最复杂、最难懂的莫过人,懂得人就会懂得你自己。
希腊人把懂得你自己看做是人生最高的智慧。
人不像木石只有物质,而且还有意识,有情感,有意志,总而言之,有心灵。
西方有一句古谚:人有一半是魔鬼,一半是仙子。
魔鬼固诡诈多端,而仙子也缥缈难测。
作为一种动物,人是人类学的研究对象。
他经过无数亿万年才由单细胞生物发展到类人猿,又经过无数亿万年才由类人猿发展到人。
正如人的面貌还有类人猿的遗迹,人的习性中也还保留着一些兽性,即心理学家所说的本能。
我们这些文明人是由原始人或野蛮人演变来的,除兽性之外还保留着原始人的一些习性。
要了解现代社会中的人,还需要了解我们的原始祖先。
所以马克思特别重视摩根的《古代社会》,把它细读过并且加过评注。
恩格斯也根据古代社会的资料写出了《家庭、私有制和国家的起源》。
在《自然辩证法》一书中,恩格斯还详细论述了劳动在从猿到人变过程中的作用,谈到了人手的演变、进化的历史,这对研究美学是特别重要的。
古代不仅是家庭、私有制和国家政权的摇篮,而且也是宗教、神话和艺术的发祥地。
数典不能忘祖,这笔账不能不算。
从人类学和古代社会的研究来看,艺术和美并不是起源于抽象概念,而是起源于吃饭穿衣、男婚女嫁、猎获野兽、打仗来劫掠食物和女俘等日常生活实践中极平凡卑微的活动。
中国的儒家有一句老话食、色,性也。
艺术和美也最先见于食色。
汉文美字就起源于羊羹的味道,中外都用趣味来指审美力。
原始民族很早就讲究美,从事艺术活动。
他们用发亮耀眼的颜料把身体涂得漆黑或绯红,用唱歌和跳舞来吸引情侣,或庆祝狩猎、战争的胜利。
在近代,人是心理学研究的主要对象。
一个活人时时刻刻都要和外界事物(自然和社会)打交道,这就是生活。
生活是人从实践到认识再从认识到实践的不断反复流的发展过程。
