To the people who came to Christopher Morley Park in Roslyn, he had no name. To them, he was “the ice cream man”. He was just two hands and a smile handing back ice cream from the van(面包车)window. To me, he was my older brother, Andrew.

Once, he worked on Wall Street. But later he spent his days selling ice cream to an endless line of kids, moms and dads in swimming suits, perhaps daydreaming of a beach faraway.

All day long, while he sold bags of potato chips, cans of soda, and all types of ice cream, he would do this sort of robotic motion—turn to the right, stoop down, hand the item out of the window and collect the money.

His drinking days were over now. They neared their end one night after he took a severe beating when someone followed him home and robbed him when he was drunk. It left him memories of pain and misery. He was determined he would never take another drink again.

One day years later, I went to look for him. I slipped into the high driver’s seat and sat quietly watching him work. Occasionally, he would ask me to hand him a diet root beer or a bag of chips for sale, all the time

bending over as he worked the long line.

As I watched him sell ice cream from a van window, he taught me something about living this life that we all pass through too quickly. It was a lesson about trying to live it with grace and dignity and style, no matter what.

He died in March 1999. He had served in the Army for two years in Europe in the 1950s. They gave him a soldier’s funeral with a folded flag.

24. Where was Andrew likely to sell the ice cream?

A. On a train.

B. In a park.

C. On Wall Street.

D. In a supermarket.

25. What did the author think of Andrew’s job?

A. Busy and hard.

B. Challenging but time-consuming.

C. Honorable and well-paid.

D. Busy but badly-paid.

26. What does the underlined word “they” in Paragraph 4 refer to?

A. The robbers.

B. The painful memories.

C. The consumers.

D. The drinking days.

27. What is the author’s purpose in writing the text?

A. To remember his brother.

B. To tell a regrettable story.

C. To share a sad life lesson.

D. To state his attitude towards life.

C

Self-driving vehicles will rely on cameras, sensors and artificial intelligence(AI)to recognize and respond to road and traffic conditions, but sensing is the most effective for objects and movement in the neighborhood of the vehicle. Not everything important in a car’s environment will be caught by the vehicle’s camera. Another vehicle approaching at high speed on a collision (碰撞)track might not be visible until it’s too late. This is why vehicle-to-vehicle communication is undergoing rapid development. Our research shows that cars will need to be able to chat and cooperate on the road, although the technical challenges are considerable.

Applications for vehicle-to-vehicle communication range from vehicles driving together in a row, to safety messages about nearby emergency vehicles. Vehicles could alert each other to avoid collisions or share notices about passers-by and bicycles.

From as far as several hundred metres away, vehicles could exchange messages with one another or receive information from roadside units(RSUs)about nearby incidents or dangerous road conditions through 4G network A high level of A1 seems required for such vehicles, not only to self-drive from A to B, but also to react intelligently to messages received. Vehicles will need to plan, reason, strategize and adapt in the light of information received in real time and to carry out cooperative behaviours. For example, a group of autonomous vehicles might avoid a route together because of potential risks, or a vehicle could decide to drop someone off earlier due to messages received, a foreseen crowding ahead.

Further applications of vehicle-to-vehicle communication are still being researched, including how to perform cooperative behaviour.

28. What is the first paragraph mainly about?

A. The reasons for the accidents by self-driving vehicles.

B. The research about applications for self-driving vehicles.

C. The importance of artificial intelligence of self-driving vehicles.

D. The reasons for developing communication between self-driving vehicles.

29. What does the underlined word “alert” mean in Paragraph 2?

A. Alarm.

B. Condemn.

C. Ignore.

D. Govern.

30. What can we learn about roadside units (RSUs)?

A. They classify the vehicles on the road.

B. They can improve bad road conditions.

C. They take over the passing vehicles.

D. They serve as efficient information stations.

31. What is the best title for the text?

A. When do vehicles communicate?

B. The reasons why a high level of AI is important

C. Vehicle-to-vehicle communication is coming

D. What do applications for vehicle-to-vehicle communication need?

D

Food storing is common in members of the crow(乌鸦)family. A new study tested the birds outside this naturally occurring behaviour, which may have evolved(进化)specifically because it gives crows a survival advantage. Some crow species are known to naturally use tools to recover food. So the researchers tested whether the birds could store and recover a tool so they could get it at their food after a gap of 17 hours—something we wouldn’t expect them to do nat urally. But they were able to instantly select the tool out of a number of unnecessary items.

In another experiment, the researchers taught crows to select a token (礼品券)from a number of items so that they could then exchange for food. Again, the birds then showed that they could plan for the future using this new behaviour. This is different from all of the previous studies in future planning, which have focused on naturally occurring behaviour. For example, we know that chimpanzees select, transport and save appropriate tools for future needs.

These studies have shown that animals can plan for the future—but they left an important question open for debate. Are animals only able to plan to use abilities that have evolved to give them a specific advantage, or can they flexibly and intelligently apply planning behaviour across various actions? Most critics would say the former, as the animals were tested in naturally occurring behaviours.

But the new research provides the first evidence that animal species can plan for the future using behaviour that doesn’t typically occur in nature. This supports the view that at least some recognitive abilities in animals don’t evolve just in response to specific problems. Instead, it suggests that animals can apply these behaviours flexibly across problems in a similar way to humans. We need to investigate how flexible behaviour evolved. Then we might be able to see how crows’ ability to plan for the future fits in with their broader cognitive powers.

32. What’s the new finding about some crows according to Paragraph 1?

A. They can store food.

B. They can use tools to recover food.

C. They can store and recover tools.

D. They can select and store food.

33. What are crows trained by scientists to do when given a token?

A. Reject it casually.

B. Exchange it for food.

C. Save it as their food.

D. Build a nest with it.

34. What do scientists think of the studies that animals can plan for the future?

A. They are controversial.

B. They are disappointing.

C. They are contradictory.

D. They are convincing.

35. What can be inferred about recognitive abilities in animals?

A. They develop only with age.

B. It is uncle ar how they’ve evolved now.

C. No animals but crows benefit from them.

D. Planning for the future helps their evolution.

How to Become an Activist (活动家)

Activists are people who see the need for change and devote their time to doing something about it.

36 If you are interested in it you can do so.

B. Join an organization that supports your cause.

C. They are driven by passion and a vision for a better future.

D. If you do volunteer work, invite them to volunteer with you.

九年级第一次模拟考试数学试卷分析

2018年九年级第一次模拟考试数学试卷分析及复习备考 一模考试是中考前的适应性训练与平时复习有效结合的载体,它一方面检验了学生在中考第一轮复习后所取得的阶段性成绩,可以从中找到自身的不足,发现存在的问题,并能及时调整第二阶段复习的重点和目标;另一方面也为教师下一步更有针对性的复习提供一些最新的思路和比较有价值的复习方向。从整张试卷反馈的各方面指标来看,具有一定的导向性,它与中考的精神会有多大的一致在这里不敢断言,但至少呈现出以下一些亮点: 一、试卷分析 (一)试卷内容分析 1、试卷结构符合中考要求 试卷满分120分,选择为8小题,填空7小题,且每题为一空,解答题8小题。试卷难度系数稍难,安排有序,层次合理。试卷整体质量比较高,体现了省中考纲要对学生掌握知识和应用能力的要求,同时对第二轮中考复习指明了一些思路和好的策略。 2、准确把握对数学知识与技能的考查 全卷基础知识、基本技能的考查题覆盖面广,基本题如填空、选择部分以及计算、全等形证明、统计等都以常规题型为主,并以基本要求为考查目的,强调知识的直接应用,考查了学生的基本运算能力、数据处理能力、阅读理解能力、分析问题与解决问题的能力。试卷既保证了大多数同学对基础知识的理解和简单运用,让他们有成功的体验;又有一定的区分度,给学有余力的同学创造了展示自我的空间,有助于考生较好地发挥思维水平。 3、重视与实际生活相联系 全卷设置了具有显示情景式的实际问题如7、19、20题,这些试题贴近学生的实际生活,体现了数学与生活的联系。将考查的知识点融入生活中,可以引导学生经历解决实际问题的过程,体验运用数学知识解决实际问题的情感,考查学生从实际问题中抽象数学模型的能力,培养用数学,做数学的意识, 4、注重考查学生的创新意识 试卷以动点题为压轴题,考查学生的综合数学素养和创新能力。22,23 题图形较熟悉,问题设置也较简明,使学生入手容易,但得满分较难,需要较高的数学素养。本题有利于激活学生的创新意识、发展思维品质,堤高数学素养。 (二)答卷情况分析 我校学生一模考试共有特优32人,优秀216人。答题中存在问题,选择题第7、8题,填空题13、14、15题出错率教高,原因是学生对旋转、翻折、与圆有关几何问题掌握及灵活运用能力不足。16、19题规范化上存在问题。22、23题失分严重,原因综合素质差,数型结合意识不强,不能整体感知几何图形,找不到知识之间的联系点,缺乏分类讨论思想。另外答题中也存在没有认真看题,审题不清,在读题、审题环节上的马虎。 二、第二轮复习应该注意的几个问题 1、第二轮复习不再以节、章、单元为单位,而是以专题为单位,专题的划分要合理,选择要准,有代表性,切忌面面俱到;要有针对性,重要处要狠下功夫,不惜“浪费”时间,舍得投入精力 2、注重解题后的反思。解题之合要反思,从六个方面进行 (1)思因果:思考在解题过程中的运用了那些知识点、已知条件及它们之间的关系,还有哪些条件没有用过,结果与题意或实际生活是否相符等。

初三化学第一次模拟考试质量分析初三化学备课组 一(对试卷的整体评价: 本次试卷共有四个大题:分别为选择题、填空题、实验题和计算题。试题特点:题型稳定,难度中等,学科重点突出,注重对基础知识、基本技能和基本方法的考核,同时试题同样注重思维逻辑性和严密性。题量特点:适中。但由于新课刚结束还来不及进行系统的复习,所以本次考试存在一定问题,成绩不够理想。 二、从试卷答题情况分析,存在问题: 1、基础知识不扎实,重要的知识点理解不清,几大化学用语的书写急需强化。例如分子、原子的概念,物质的名称、俗称、化学式,质量守恒定律的运用,金属活动性的使用,化学反应的类型,化学用语、化学方程式的书写等等,都存在很大的问题。 2、获取新信息的能力和整合新化学知识的能力有待提高。例如第一大题的 3、7小题,第四大题的23小题等,有一半以上的同学全部答错。 3、语言描述不够全面、严密。如学生分不清结论与现象。总把现象描述成结论。 三、从考试成绩分析: 本次考试总分为60分。考试成绩中学生两极分化及其严重,满分的全校有2个,50分以上55人,但20分以下的人数为34人,考个位数的有3人。不及格人数有116人,占比45.8%。在班级情况看,汤校长任教的三(1)班分数遥遥领先,平均分39.3分,其余四个班成绩差不多,在35分左右。 四、下阶段措施:

从考试结果看,学生的基础知识掌握得不好,在综合应用方面较欠缺。在后阶段教学中,我们初三化学组努力做到: 1、加强双基教学,加强基础知识的落实。初中化学内容多, 时间短,适当加强记忆才能取得好的效果,对重要的考点, 整理成一定题目,让不及格的同学反复练习,力求人人过 关。 2、提高及格率,应重点关注学习困难学生。以模拟考试试卷 为例,明确告诉他们现在的考题都不难,只要有信心和 恒心,都是可以成功的。同时在复习《中考总复习》时, 将书上的知识点再重新给他们进行梳理,按单元再次将 基础知识点归纳总结,特别是将可以通过背诵记忆的简 单知识点罗列出来,要求学生抄写、记忆,并进行小测 或抽查。由于考试的计算题难度不高,在以后的复习计 算题时,可以开展计算题专题训练,让学生真正体会到 计算题不难,摸索到解题的基本方法,增强解答计算题 的信心,提高计算的得分率,减少出现最后一道大题放 空白的现象。 3、实验是薄弱环节,学生在综合性实验题中普遍失分,而且 以后实验题在中考中占比将增加。在平时的教学中切实加 强实验教学,将实验作为提高学生兴趣、培养学生能力的 突破口。 4(学生的阅读理解能力、应变能力、分析、应用能力较薄弱。 根据课改和中考改革的要求,在教学中打破学科的封闭体 系,从身边谈起,多联系生活、生产、社会实际,不断地

【物理】人教版中考物理第一次模拟考试精选试卷测试卷附答案

一、初三物理欧姆定律易错压轴题(难) 1.要测量一个阻值约为几百欧的电阻R x。实验室提供的器材有:电源(电压为3V)、学生用电流表(量程为0~0.6A、0~3A)、学生用电压表(量程为0~3V、0~15V)、滑动变阻器R1和电阻箱R2(0~9999Ω5A)各一个,开关、导线若干。 (1)小明用伏安法测量该电阻,如图是小明连接的电路。接通电路后,观察到电流表指针不偏转,示数为零,电压表示数为2V。请你判断: 电路中哪一个元件发生了什么故障?答:______; (2)在排除故障换用新元件后,经检查电路完好。闭合开关,逐渐减小滑动变阻器的接入电阻至最小,电压表有示数,但电流表的指针几乎不偏转,电流太小的原因是______。所以按小明所选的器材不能用伏安法测出该电阻的值; (3)请你帮助小明在实验室所提供的器材中选择合适的器材,设计实验方案测出该电阻的值; (a)画出实验电路图______; (b)实验步骤:按图连接好电路;闭合S1调节滑动变阻器,使电压表显示合适的值;断开S1闭合S2,______;读出电阻箱的阻值R; (c)写出待测电阻R x的表达式:______。 【答案】电流表短路待测电阻阻值太大保持滑片位置不 变,调节电阻箱阻值,使电压表示数与闭合S1时相同R x=R 【解析】 【分析】 (1)常见电路故障有断路与短路,根据电路故障现象分析电路故障原因。 (2)根据欧姆定律,在电压不变的情况下,若电路的电阻增大,则电路中的电流减小,若电阻值很大,则电路中的电流会很小。若电流值小于电流表的分度值时,将无法准确地测出电流值。

(3)根据实验电路图可知,实验时有电压表,没有电流表,可根据并联电路各支路两端的电压特点进行实验,即:连接好电路图后,用电压表测出待测电阻两端电压,再将开关与电阻箱连接并调节电阻箱的阻值使电压表的示数不变,根据并联电路的电压相等和欧姆定律可知待测电阻的阻值与电阻箱的阻值相等;据此设计实验步骤。 【详解】 (1)[1]接通电路,电流表指针不偏转,示数为零,而电压表示数为2V,说明电流表被短路。 (2)[2]由于电源电压为3V,而电阻R x的阻值大约为几百欧,根据欧姆定律电路中的电流太小。 (3)[3]可以应用等效法测待测电阻阻值,待测电阻与电阻箱并联,实验电路图如图所示: [4]实验步骤:按图连接好电路;闭合S1调节滑动变阻器,使电压表显示合适的值;断开S1闭合S2,保持滑片位置不变,调节电阻箱阻值,使电压表示数与闭合S1时相同;读出电阻箱的阻值R。 [5]写出待测电阻R x的表达式 R x=R 【点评】 本题的难点较多,一是电流表量程的选取,二是故障原因的判断,三是没有电压表测电阻的方法:根据并联电路各支路两端的电压相等这一特点设计实验,着重体现了等效替代法 在实验中的具体应用。 2.小明同学用如图甲所示的电路,探究“电流与电压和电阻的关系”,电源电压15V保持不变,滑动变阻器的规格是“50Ω1A”,满足测量需求的电流表、电压表各一个,阻值为10Ω、20Ω、30Ω、40Ω的定值电阻各1个。 (1)连接电路时开关应处于_____(填“断开”或“闭合”)状态。 (2)根据图甲所示的电路图,将图乙所示的实物图连接完整,要求闭合S后,滑片P向左移
