语篇解读：作者的儿子大学毕业前求职面试，因为礼貌和宽宏大量而意外受雇，获得了经济危机时期难得的工作机会。

1．A.As to B．Due to

C．Instead of D．Contrary to

解析：选B根据句意可知应该选择B。due to“由于”，表原因。as to“至于”；instead of“代替”；contrary to“与……相反”。

2．A.promote B．train

C．employ D．discover

解析：选C由于金融危机的缘故，没有几家公司愿意雇用(employ)新的职员。

3．A.encouraged B．allowed

C．supposed D．intended

解析：选D作者的儿子选中了一家公司，该公司只打算(be intended to)雇用一名新职员。be supposed to do sth.“被要求做某事，理应做某事”。

4．A.while B．since

C．though D．if

解析：选A公司只招一人，但却有二十多人报名。while表示对比，故选A。

5．A.meet B．attract

C．decide D．represent

解析：选C第一轮面试之后选择三个人进入最后一轮的面试，最后从中确定(decide)一个人受雇。

6．A.slowly B．smoothly

C．secretly D．silently

解析：选B根据and 后面的内容可知一切进展很顺利(smoothly)。

7．A.members B．students

C．friends D．candidates

解析：选D由第二段第一句内容可知共有三个候选人(candidate)，即作者的儿子和另外两位。误解分析：虽然作者的儿子大学没有毕业仍然是学生，但是全文并没有交代其他应聘者也是学生，文章也没有说那家公司只招学生。

8．A.waiting for B．watching over

C．thinking about D．looking into

解析：选A儿子和另外两位候选人按时到达现场，当然是为了等候(wait for)面试。watch over“保护”；think about“思考”；look into“调查”。

9．A.formal B．simple

C．funny D．strange

解析：选B根据面试官说话的内容可知，面试很简单。误解分析：容易误选D项，正常面试会很复杂，而这个面试却只说了一句话就结束了，因此认为很奇怪，但是空前面的副词与此选项不符。另外Unexpectedly也是排除D项的依据。

10．https://www.doczj.com/doc/063090591.html,rmation B．notice

C．order D．return

解析：选B面试官只说了一句话，就让这三个人回去等待通知(notice)。

11．A.result B．choice

C．mark D．idea

解析：选A面试官让他们等公司三天之后确定的面试结果。

12．A.annoyed B．puzzled

C．disappointed D．shocked

解析：选C上文提到儿子收到了面试的结果，通知他没有被雇用，对于这个结果，全家人当然应该感到很失望。

13．A.doubtfully B．excitedly

C．calmly D．worriedly

解析：选B儿子突然打电话说被录用了，此时他当然是非常兴奋的。

14．A.matter B．cause

C．conclusion D．interview

解析：选A儿子先是未被录用，而傍晚突然打电话说被录用了，因此作者迫不及待地想知道事情的经过。

15．A.middle B．ending

C．part D．course

解析：选C实际上他们第一次给儿子发的短信也是他们面试测试的一部分，下句说三个入围者都收到了短信。

16．A.way B．reply

C．problem D．question

解析：选B当天早晨，三个人收到了同样的短信，但只有作者的儿子对短信的回复(reply)是“谢谢”。

17．A.changed B．grew

C．came D．developed

解析：选C直到那时，作者才知道他儿子的希望是怎么来的。

18．A.expect B．forget

C．dislike D．regret

解析：选B当你失望的时候不要忘了(forget)对使你失望的人说声谢谢。

19．A.generosity B．curiosity

C．dignity D．personality

解析：选A空前面的修饰词语grand是解题关键。失望时仍然道谢，可以表示你对别人工作的尊重并显示出你的宽宏大量。

20．A.abilities B．strengths

C．challenges D．opportunities

解析：选D正是儿子的一句“谢谢”才使他在和其他两位相比较时占了优势，获得了这次难得的工作机会。get the upper hand“占优势”，in terms of“就……而言”。

Ⅴ.阅读理解

There are almost limitless things to do at the seaside.For an enjoyable summer day or night, some that are the most fun can be simple, inexpensive or absolutely free.

Frolic:_Summer at the seaside is for as many activities as you can

stand in the sand.Play frisbee (飞盘), sand volleyball or any beach-free

sport.Jog or run while you feel the soft sand each step.If it's nice and

windy, go fly a kite!

Picnic: If you're a bit lazy as you sun and relax on the beach, you can buy takeout (外卖食物) from nearby shops.If you're there with a big family outing, you may prefer to pack and bring baskets of your favorite foods and drinks.

Sand castles: For anyone who wishes they were still kids, building castles in the sand is fun at the seashore.If you're feeling really creative, add fishes, frogs and whatever else your modeling skills can construct.

Explore: If there are hiking or biking trails along the shore or nearby, take an action to discover what's around to be collected.Seashells and washed-up ocean flora (植物群) are fun to hunt, although finding a valuable diamond ring in the sand is much more satisfying.

Socialize: Meet all kinds of people.If kids are with you, they're natural socializers, and will easily join others in games and other fun things to do together.Set up a volleyball net on the beach, and soon others will join the game.

Nothing: For some people the top activity at the seaside is inactivity.That means doing absolutely nothing.After all, you've come to the beach to relax on the warm sand, and nowhere in the world is there a more comfortable place for it.

语篇解读：本文主要介绍了在海边旅游时的几种休闲活动。

1．In the first paragraph the author ________.

A．advertises a scenic spot

B．describes the beautiful seaside

C．shows visitors can do many things at the seaside

D．introduces the things that can be brought to the seaside

解析：选C段落大意题。根据第一段可知，作者指出在海边可做的事情很多，有些很有意思而且成本低廉，故选C项。

2．Which can best explain the underlined word “Frolic”？

A．Tips on safety.

B．Full preparation.

C．Famous players.

D．Lively and enjoyable activity.

解析：选D词义猜测题。根据第二段可知，本段主要介绍了在沙滩上可参加的多种“欢乐的活动”，如玩飞盘、沙滩排球、跑步、放风筝等，故选D项。

3．According to the passage, which of the following is NOT suggested by the author?

A．Having a picnic with your family.

B．Making friends with all kinds of people.

C．Playing many kinds of games at the beach.

D．Searching for valuable jewelry in the sand.

解析：选D推理判断题。根据倒数第三段最后一句可知，虽然说在沙滩找到钻戒会更加令人满意，但作者并没有建议读者去这么做，而且建议去寻找贝壳、植物等。

4．According to the passage, if you do nothing at the seaside, ________.

A．you can still relax yourself

B．you might feel uncomfortable

C．you miss a chance to enjoy yourself

D．you are not advised to go to the seaside again

解析：选A细节理解题。根据最后一段最后一句中的“you've come to the beach to relax on the warm sand”可知，在沙滩上即便什么都不做，这里也是放松的最佳地点，故A项正确。

Ⅵ.短文改错

Dear Abby，

How are you? I've got a wonderful news to tell you. I had been offered a scholarship at a university in Australia for my further education. One hundred student took the exam for it, but only a few were chosen and I was one of them. Therefore, my parents are not happy about it. They are strong against my going there.

They advise me to study in the capital instead. Then I'll able to continue living with them. How can I make them receive the fact that I have grown up?

Best wishes.

课时跟踪检测(二十三) 电场能的性质

课时跟踪检测（二十三）电场能的性质 [A级——基础小题练熟练快] 1．(2019·湖北八校联考)下列说法正确的是() A．带电粒子仅在电场力的作用下一定做匀变速运动 B．带电粒子仅在电场力的作用下运动时，动能一定增加 C．电场力做正功，带电粒子的电势一定降低 D．电场力做正功，带电粒子的电势能一定减少 解析：选D只有电场是匀强电场时，带电粒子仅在电场力的作用下做匀变速运动，A 错误；如果电场力做负功，则动能减小，B错误；电场力做正功，电势能一定减小，负电荷从低电势向高电势运动，故C错误，D正确。 2.(2020·山东济南模拟)如图所示，等量异种点电荷P、Q连线中点 处有一电子，在外力F作用下处于静止状态。现让电荷Q沿连线向右 移动一小段距离，此过程中电子一直处于静止状态。下列说法正确的是() A．外力F逐渐减小，电子的电势能逐渐增大 B．外力F逐渐增大，电子的电势能逐渐增大 C．外力F逐渐增大，电子的电势能逐渐减小 D．外力F逐渐减小，电子的电势能逐渐减小 解析：选D由题意可知，外力F向右，则电场力向左，可知P带正电，Q带负电；当电荷Q沿连线向右移动一小段距离时，电子所在的位置场强减小，电势升高，则电子受的电场力减小，外力F逐渐减小，电子的电势能降低，故选项D正确，A、B、C错误。 3.(2019·浙江东阳中学模拟)如图所示，MN是由一个正点电荷Q产生的 电场中的一条电场线，一个带正电的粒子＋q飞入电场后，在电场力的作用 下沿一条曲线运动，先后通过a、b两点，不计粒子的重力，则() A．粒子在a点的加速度小于在b点的加速度 B．a点电势φa小于b点电势φb C．粒子在a点的动能E k a小于在b点的动能E k b D．粒子在a点的电势能E p a小于在b点的电势能E p b 解析：选C由题图可知粒子受力应向左方，因粒子带正电，故电场线的方向应向左，故正点电荷Q应在N一侧，故a处的场强大于b处的场强，故粒子在a处的电场力大于b

【拔高教育】2017_2018学年高中物理课时跟踪检测六生活中的圆周运动新人教版必修2

课时跟踪检测（六）生活中的圆周运动 1．在水平路面上转弯的汽车，提供向心力的是( ) A．重力和支持力的合力 B．静摩擦力 C．滑动摩擦力 D．重力、支持力和牵引力的合力 解析：选B 汽车在水平路面上转弯时，与线速度方向垂直且指向圆心的静摩擦力提供汽车转弯所需的向心力。 2．关于铁轨转弯处内、外轨间的高度关系，下列说法中正确的是( ) A．内、外轨一样高，以防列车倾倒造成翻车事故 B．因为列车转弯处有向内倾倒的可能，故一般使内轨高于外轨，以防列车翻倒 C．外轨比内轨略高，这样可以使列车顺利转弯，减少车轮对铁轨的挤压 D．以上说法均不正确 解析：选C 外轨略高于内轨，这样轨道对火车的支持力垂直于轨道平面向上，它与火车的重力的合力沿水平方向指向圆心，消除或减小车轮和轨道间的侧向挤压，有效地保护了轨道和车轮。 3．如图1所示，在盛满水的试管中装有一个小蜡块，小蜡块所受浮力略大于重力，当用手握住A端让试管在竖直平面内左右快速摆动时，关于蜡块的运动，以下说法正确的是( ) 图1 A．与试管保持相对静止 B．向B端运动，可以到达B端 C．向A端运动，可以到达A端 D．无法确定 解析：选C 试管快速摆动，试管中的水和浸在水中的蜡块都有做离心运动的趋势(尽管试管不是做完整的圆周运动，且运动的方向也不断变化，但并不影响问题的实质)，但因为蜡块的密度小于水的密度，蜡块被水挤压向下运动。只要摆动速度足够大且时间足够长，蜡块就能一直运动到手握的A端，故C正确。

4．一汽车通过拱形桥顶点时速度为10 m/s ，车对桥顶的压力为车重的3 4，如果要使汽 车在桥顶对桥面没有压力，车速至少为( ) A ．15 m/s B ．20 m/s C ．25 m/s D ．30 m/s 解析：选B 当F N ＝34G 时，因为G －F N ＝m v 2 r ，所以14G ＝m v 2 r ，当F N ＝0时，G ＝m v ′ 2 r ，所 以v ′＝2v ＝20 m/s 。 5．在环绕地球做匀速圆周飞行的宇宙飞船实验舱内，下列实验可以正常进行的是( ) A ．用天平测物体质量 B ．用弹簧测力计测物体的重力 C ．平抛运动实验 D ．用电子手表记录时间 解析：选D 绕地球做匀速圆周运动的宇宙飞船及船内物体处于完全失重状态，所以物体对天平的压力为零，因而测不出其质量，故A 项无法正常进行。准确地说处于完全失重状态下，与重力相关的物理实验都将失败，故B 、C 项均无法正常进行。电子表记录时间与重力无关，故D 项可以正常进行。 6.(多选)如图2所示，A 、B 两物体放在旋转的圆台上，两物体与圆台面间的动摩擦因数均为μ，两物体的质量相等，A 物体离转轴的距离是B 物体离转轴距离的2倍，当圆台旋转时，A 、B 均未滑动，则下列说法中正确的是( ) 图2 A ．A 物体所受的摩擦力小 B ．A 物体的向心加速度大 C ．当圆台的转速增加时，A 先滑动 D ．当圆台的转速增加时，B 先滑动 解析：选BC 当A 、B 两物体在圆台上随圆台一起旋转时，它们所需的向心力均由来自圆台的静摩擦力提供，所以F A ＝F f A ＝m A r A ω2 ；F B ＝F f B ＝m B r B ω2 ，由题意可知：r A >r B ，所以F f A >F f B ，A 错误；由牛顿第二定律可知，F ＝ma ，a ＝r ω2 ，所以a A >a B ，B 正确；当圆台的转速增大时，角速度ω也随之增大，由于r A >r B ，所以A 物体所需向心力增大得快，所以A 物体先出现合力(即摩擦力)不足以提供圆周运动所需向心力的情况，A 先滑动，C 正确，D 错误。
