一.本题共12小题,每小题4分,共48分.在每小题给出的四个选项中,有一个选项或多个选项正确.全部选对的得4分,选不全的得2分,有选错的或不答的得0分.

1.(4分)关于力的下列各种说法中,正确的是()

有江西省瑞金市这个说法吗

①力是改变物体的运动状态的原因

②力是产生形变的原因

③只有相互接触的物体才有力的作用

④在国际单位制中,力的单位是牛顿,简称牛,符号为N.

A. ①②③ B. ②③④ C. ①②④ D.①③④

考点: 力的概念及其矢量性;力学单位制.

分析: 本题根据力的作用效果、产生条件和单位进行分析.力有两种作用效果:一是改变物体的运动状态;二是使物体产生形变.力有接触力与不接触力.力的单位是牛顿. 解答: 解:①根据牛顿第二定律得知:力是产生加速度的原因,即是改变物体的运动状态的原因,故①正确.有江西省瑞金市这个说法吗

②力能使物体产生形变,故②正确.

③力有不接触力和接触力两类,不接触也可能有力作用,比如重力、电场力和磁场力,故③错误.

④在国际单位制中,力的单位是牛顿,简称牛,符号为N,故④正确.故C正确. 故选:C.

点评: 本题考查对力的作用效果、力的类型和单位的理解和掌握情况,基础题.

2.(4分)物体做自由落体运动时,某物理量随时间的变化关系如图所示,由图可知,纵轴表示的这个物理量可能是()

A. 位移 B. 路程 C. 速度 D.加速度

考点: 自由落体运动;匀变速直线运动的图像.

专题: 自由落体运动专题.

分析: 物体只在重力的作用下,初速度为零的运动,叫做自由落体运动.自由落体运动是一种理想状态下的物理模型;图中相关物理量与时间成正比.

解答: 解:AB、位移h=gt,与时间不成正比,同理路程也不与时间成正比,故AB错误;

C、根据速度公式,有v=gt=10t,故v与t成正比,故C正确;

D、加速度a=g,恒定不变,故D错误;

2

故选:C.

点评: 本题关键明确自由落体运动是初速度为零的匀加速直线运动,然后根据运动学公式列式分析.

3.(4分)汽车关闭油门后做匀减速直线运动,最后停下来.在此过程中,最后三段连续相等的时间间隔内的平均速度之比为()

A. 1:1:1 B. 5:3:1 C. 9:4:1 D.3:2:1

考点: 匀变速直线运动的位移与时间的关系;平均速度.

专题: 直线运动规律专题.

分析: 根据逆向思维求出最后三段连续相等的时间间隔内的位移之比,再根据平均速度公式求出平均速度之比.

解答: 解:初速度为零的匀加速直线运动,在相等时间内的位移之比为1:3:5:7:…根据逆向思维,知最后三段连续相等的时间间隔内位移之比为5:3:1.因为三段时间相等,所以平均速度之比为5:3:1.故B正确,A、C、D错误.

故选B.

点评: 解决本题的关键掌握初速度为零的匀变速直线运动的推论,在相等时间内的位移之比为1:3:5:7:…以及知道本题采取逆向思维解决比较简单.

4.(4分)如图是做直线运动的甲、乙两物体的s﹣t图象,下列说法正确的是()

A. 甲启动的时刻比乙早t1s B. 当 t=t2s时,两物体相遇

C. 当t=t2s时,两物体相距最远 D. 当t=t3s时,两物体相距s1m

有江西省瑞金市这个说法吗

考点: 匀变速直线运动的位移与时间的关系.

专题: 直线运动规律专题.

分析: 本题是位移﹣时间图象,根据图象直接可以读出某个时刻,两个物体的位置,从图上也可以读出出发时间先后,出发点距离等等.

解答: 解:A、由图看出,甲从0时刻出发,而乙t1时刻出发,则甲比乙早出发时间t1.故A正确.

B、由图看出,当 t=t2时,甲乙两物体处于同一位置,相遇,故B正确,C错误;

C、当t=t3s时.甲处于x=0处,乙除以x′=s1位置处,所以两物体相距s1m,故D正确. 故选:ABD

点评: 由位移图象能直接读出物体出发的时刻和位置,抓住图象的斜率等于速率可比较速度大小、分析物体的运动情况.

5.(4分)若汽车的加速度方向与速度方向一致,当加速度减小时,则()

A. 汽车的速度也减小

B. 汽车的速度仍在增大

第三篇 有江西省瑞金市这个说法吗
《江西省瑞金市2014高考英语 阅读理解和完形填空训练(3)》

江西省瑞金市2014高考英语阅读理解和完形填空训练(3)(含答案)

What is eBay? The simple answer is that it is a global trading platform where nearly anyone can trade practically anything. People can sell and buy all kinds of products and goods,including cars, movies and DVDs, sporting goods, travel tickets, musical instruments, clothes and shoes — the list goes on and on.

The idea came from Pierre Omidyar, who was born in Paris and moved to Washington when he was still a child. At high school, he became very interested in computer programming and after graduating from Tufts University in 1988, he worked for the next few years as a computer engineer. In his free time he started eBay as a kind of hobby, at first offering the service free by word of mouth. By 1996 there was so much traffic on the website that he had to upgrade(升级) and he began charging a fee to members. Joined by a friend, Peter Skoll, and in 1998 by his capable CEO, Meg Whitman, he_has_never_looked_back. Even in the great.com crashes of the late 1990s, eBay has gone from strength to strength. It is now one of the ten most visited online shopping websites on the Internet.

eBay sells connections, not goods, putting buyer and seller into contact with each other. All you have to do is take an e photo, write a description, fill out a sales form and you are in business; the world is your market place. Of course for each item (商品)sold eBay gets a percentage and that is a great deal of money. Every day there are more than sixteen million items listed on eBay and eighty percent of the items are sold.

[语篇解读] 文章向我们介绍了eBay网的一些情况。

1.We learn from the text that eBay provides people with ________. A. a way of buying and selling goods B. a website for them to upgrade C. a place to exhibit their own photos D. a chance to buy things at low prices [解析] 根据第一段内容可知。 [答案] A

2.Why did Pierre create eBay after graduating from university? A. For fun. B. To make money.

C. For gathering the engineers. D. To fulfill a task of his company. [解析] 由第二段第三句话可知。 [答案] A

3.From “he has never looked back ”in Paragraph 2 we learn that Pierre________. A. did not feel lonely B. was always hopeful

C. did not think about the past D. became more and more successful

[解析] Peter由原来的业余爱好开始,逐步走向成功,创建了世界知名网站。 [答案] D

4.How does eBay make money from its website? A. By bringing sellers together. B. By charging for each sale. C. By listing items online. D. By making e photos.

[解析] 由最后一段第一句话可知,这个网站通过提供交易平台,然后收取适当的服务费。因此B项正确。

[答案] B

It’s great fun to explore (探索) new places—it feels like an adventure, even when you know you’re not the first to have been there. But make sure not to get lost or waste time going round in circles.

● Do the map reading if you’re being driven somewhere. It’ll be easier if you keep turning the map so it follows the direction you’ re traveling in. Keep looking ahead so that you can give the driver lots of warning before having to make a turn, or you’ll have to move to the back seat. ● Get a group of friends together and go exploring. You’ll need a good map, a compass (指南针), a raincoat, a cell phone to call for help in case you get lost, and a bit of spare cash for emergencies (应急现金). Tell someone where you’re going before you set out and let them know what time you expect to be back. The test is in not getting lost, not in seeing how fast you can go, so always stick together, waiting for slower friends to catch up.

● See if your school or a club organizes orienteering activities, in which you need a map and a compass to find your way. This can be done as a sport, with teams trying to find the way from A to B (and B to C, etc. ) in the fastest time, or simply as a spare-time activity. Either way, it’s not only good fun, but a great way to keep fit.

48. Sitting beside the driver, you should ________. A. direct the driver when necessary B. look ahead to see where there’s a turn

C. move to the back seat if feeling uncomfortable D. keep looking at the map to find a place to go to

49. Why do you need to tell someone your exploration plan before setting out?

A. To get information when in danger. B. To be saved in case of an accident.

C. To share the fun with him/her in exploration.

D. To tell him/her what’s going on with the group members. 50. Orienteering activities can ________.

A. make people work fast B. help people stay healthy C. help people organize other activities D. make people get prepared for sports

51. The text mainly talks about______? A. the fun of exploration B. what to bring for exploration

C. the way to use the map in exploration D. how to prevent getting lost in exploration

52. In Poland, who get together and cook before a weeding? A.. Children B. Men C. Women D. Fathers

Of all the problems facing modern astronomers, perhaps the most fascinating is: “Can intelligent(有智能的) life exist elsewhere?” Since the Earth is an unimportant planet moving round an unimportant star, it would be a pride on our part to suppose that we are the only intelligent beings in the universe. But to obtain proof is difficult.

The main trouble is that our neighbor worlds, the bodies in the solar system appear to be unsuitable for advanced life forms. The Moon may be ruled out at once; it has hardly any atmosphere. Venus(金星) is little better; the surface temperature is extremely high and the atmosphere is mostly carbon dioxide. Mars(火星) with a very thin atmosphere and a severe shortage of water, may well support simple plant life but there seems no hope of finding animals, while the attractive Martians of the story – tellers have long since been given up.

Of course this has not stopped the flow of bright ideas for communicating with the supposed people on Mars. In the early nineteenth century the great mathematician Gauss suggested planting tree – patterns in Siberia, so that the Martians would see them and replay suitably. Following up this idea, the Austrian scientist Karl Littrow proposed digging very wide ditches(沟) in the Sahara, triangular in patterns, and then filling them with petrol or some substance so that, when lit, the ditches would present Martian observers with a “flaming triangle” which would show the existence here of intelligent minds. Even better were the plans of Charles Cross, a French writer of the 1870’s, who wanted to build a large mirror to reflect the sun’s rays and concentrate them on the surface of Mars, thereby making a vast burning – glass. By swinging the mirror around, Cross explained it would be practicable to write words
