1. 习近平说:“我们要牢记人民对美好生活的向往就是我们的奋斗目标，坚持以人民为中心的发展思想,努力抓好保障和改善民生各项工作，不断增强人民的获得感、幸福感、安全感，不断推进全体人民共同富裕。

”从根本上讲,这是因为A. 宪法规定国家尊重和保障人权B. 公民的合法权益应得到保障C. 人民拥有管理国家事务的权利D. 我国是人民当家作主的国家【答案】D【解析】坚持以人民为中心的发展思想，努力抓好保障和改善民生各项工作，不断增强人民的获得感、幸福感、安全感，从根本上讲，这是因为我国是人民当家作主的国家，人民是国家的主人，D项正确；其他选项均不是从根本上来说明的，A、B、C项不选，故本题答案应为D。

2. 2018年1月，广东省十三届人大一次会议依法选举产生广东省第十三届全国人民代表大会代表162名。

其中少数民族4名，占2．47%，含壮族2名、瑶族1名、土家族1名；归侨5名，占3．09%；一线工人18名，占11．11%，含农民工6名；农民14名，占8．64%；专业技术人员39名，占24．07%。

材料主要反映了A. 人民民主主体的广泛性B. 人民民主的真实性C. 人民民主权利的广泛性D. 人民民主的全民性【答案】A【解析】材料中广东省第十三届全国人民代表大会的代表来自各个阶层、各个方面，这主要反映了人民民主主体的广泛性，A项正确；人民民主的真实性、人民民主权利的广泛性不是材料所体现的，B、C项不选；世界上不存在全民的民主，我国人民民主不具有全民性，D项不选，故本题答案应为A。

【点睛】区分人民民主的广泛性和真实性的关键在于准确把握它们各自的表现：广泛性表现在人民享有广泛的民主权利和民主主体具有广泛性。

真实性表现在人民当家作主的权利有制度、法律和物质的保障；随着经济发展和社会进步，广大人民的利益得到日益充分的实现；我国在人权保障方面不断取得成就。

But when a stranger received I he misa ddressed mail, she didn?t just throw it in the garbage like many people would have done. Instead, she returned the invitation, along with a sweet note and $20 as a wedding present.The sender also wrote “Live long and prosper” on the comer of the card---wo rds from “Star Trek”, probably because the young couple?s wedding invitation shows Jesse holding a light knife from “Star Wars” and Cassie holding a wand (魔杖) in a nod to th e “Harry Potter” books.The generous stranger also included $20, probably as a little gift for the wedding. The young couple put the money to good u se by going out to dinner with a friend who wouldn?t be able to attend the wedding.Warren said that she was at first confused by the returned wedding invitation. “But after I saw the note, I was just surprised and blessed that she/he would do that for a s tranger,” Warren said. “Jesse was confused al first, too-he wondered why someone had sent us money, then I read the message to him, and he was shocked and grateful.”Warren and Jones still don?t know the name of the kind stranger, but Warren sent a thank-you note to the same address to let the sender know how much her/his generosity was appreciated. The young couple plan to marry in June and thanks to the kindness of a stranger, their marriage is already off to a sweet start.24. What caused the story to happen?A. A stranger?s honesty.B. A genuine email.C. A wrong address.D. Jones?s carelessness.25. How did the stranger deal with the invitation?A. She gave it to Jesse?s aunt.B. She accepted it immediately.C.

What can be the best title for the text?A. A Sweet WeddingB. A Kind NeighborC. Stranger?s KindnessD. A Happy Young CoupleCAccording to the Guinness Book of World Records, a Sitka Spruce, growing on New Zealand?s southernmost island, is the loneliest and most distant tree on Earth. Not only is it the only tree on Campbell Island, but the nearest other tree can be found over 200 kilometers away.Located (位于) about 700 km south of Bluff, Campbell Island is one of the harshest places in the world. With strong winds blowing almost all year round, less than 600 hours of sunshineand only 40 days per year without rain, it … s not exactly a perfect place to live.It is believed that this Sitka Spruce was planted by Lord Ranfurly, a former governor of New Zealand, sometime between 1901 and 1907. According to some sources, he realized that the environment was too bad, so he took the first step to cover it in forest. His idea was never going to work because of the terrible climate of the area.Apart from being the loneliest tree on Earth, the Sitka Spruce of Campbell Island has a series of other particularities. First of all, its shape makes it look more like a huge cauliflower (花椰菜) than a tree. This is believed to have been caused by the repeated cutting every year, for decades. Luckily, no one has been cutting the tree down over the last six decades and it has grown to a height of over 10 meters.Another interesting thing about the world?s loneliest tree is that, though it is over 100 years old, it has never produced cones (球果), which suggests the tree has remained in a permanently young state.The Sitka Spruce of Campbell Island was recently in the news for helping researchers make sure that the Earth has entered an entirely new age, the Anthropocene (人类世).Who knew a lonely tree growing 200 km away from its nearest cousins could be so interesting?28. What makes the Sitka Spruce set a world record?A. Its height.B. Its old age.C. Its special shape.D. Its location.29. W hat does the underlined word “harshest” inparagraph 2 probably mean?A. Farthest.B. Hardest.C. Loneliest.D. Hottest.30. Why did Lord Ranfurly plant Sitka Spruces on the Campbell Island?A. To improve this place.B. To experiment with the tree.C. In memory of his achievement.D. To help with researchers? study.31. What affected the shape of the Sitka Spruce according to the text?A. Strong winds.B. Animals? eating.C. People?s cutting.D. Poor soil.DFor most people, Friday, which happens to be the 13th, means little more than the start of a weekend. However, to million people worldwide who suffer from paraskevidekatriaphobia (周五13 恐惧症), the combination of the day and number brings had luck. While no one knows for sure how it began, there are many theories.Experts think it starts with the fear of the number 13. The number 13 suffers from its position after 12, which is regarded as a complete number. After all, there are 12 months in a year, 12 gods of Olympus, and so on. This has caused the belief that 13 is incomplete and, therefore, unlucky.The number?s bad name is worsened by the fact that severalunfortunate incidents are linked with 13. One example is NASA?s Apollo 13 mission (任务). The seventh manned mission in the Apollo space program, launched (发射) at 13:13, never landed on moon. For some people, the mission failed because of the number 13.If you are among those who can “Shake It Off”, yo u are in great company. Taylor Swift is not affected by the number, who says, “I was bo rn on the 13th. I turned 13 on Friday t he 13th. Every time I?ve won an award I?ve been seated in either the 13th seal or the 13th row. Basically, whenever a 13 comes up in my life, it?s a good thing.”The fear of Friday appears to come mainly from ancient religion. It was the day Jesus was killed. Though the date was not the 13th, it happened after the Last Supper, which had 13 guests.When the date and day meet, people suffer from anxiety. Construction and shipbuilding workers easily become nervous, which often leads to more accidents. This, of course, further adds to their anxiety. It is reported that businesses lose more than $800 million because many people avoid traveling or shopping on this day.32. In which part of a newspaper might the passage come from?A. Society and Culture.B. Wealth and Finance.C. Health and Fitness.D. Arts and Entertainment.33. Why was Apollo 13 mission mentioned?A. To prove people?s fear of 13.B. To show the cause of the failure.C. To point out the bad luck caused by 13.D. To give examples about the bad name of 13.34 What does t he underlined part “Shake It O ff” in paragraph 4 probably mean?A. Appreciate it.B. Defend it.C. Imagine it.D. Gel rid of it.35. What can we know about paraskevidekatriaphobia from the last paragraph?A. Its origin.B. Its effect.C. Its cause.D. Its solution.第二节(共5小题；每小题2分，满分10分)根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。

河南省天一大联考2017-2018学年高一下学期阶段性测试（三）物理试题一、选择题1. 物体在恒力作用下，不可能做A. 匀加速直线运动B. 匀减速直线运动|C. 平抛运动D. 匀速圆周运动|【答案】D【解析】A、由题意可知，物体在恒力作用下，则物体受到的合力也是恒定的，即加速度恒定，则物体可以做匀变速直线运动或匀变速曲线运动，故选项ABC都是可能的；D、物体做匀变速圆周运动，合力的大小是不变，但是方向时刻的变化，故选项D是不可能的。

点睛：本题需要注意是物体受到的合力为定值，在加速度也为定值，则为匀变速运动，而匀变速运动又可分为匀变速直线运动和匀变速曲线运动，同时还要注意向心力虽然指向圆心，但是方向时刻的变化。

2. 水平转盘可以绕通过圆盘中心且垂直于盘面的竖直轴以不同的角速度转动，在转盆上放一物块，且物块姶终相对转盘静止，下列说法中正确的是A. 物块始终受到重力、支持力、摩擦力、向心力四个力的作用B. 若转盘匀速转动，物块所受摩擦力的方向与运动方向相反C. 若转盘加速转动，物块所受摩擦力的方向始终指向圆心D. 若转盘匀速转动，则物块离转盘中心越远所受静摩擦力越大【答案】D【解析】A、物块与圆盘相对静止，一起做匀速圆周运动，受到重力、支持力和静摩擦力，重力和支持力相互平衡，由静摩擦力提供向心力，所以静摩擦力的方向指向圆盘中心，与其相对圆盘相对运动趋势的方向相反，故AB错误；C、若转盘加速转动，物块所受摩擦力的方向不指向圆心，由摩擦力的一个分力指向圆心从而提供向心力，而摩擦力的另一分力使物块速度大小增大，故选项C错误；D、若转盘匀速转动，则静摩擦力提供向心力，则根据公式：远所受静摩擦力越大，故选项D正确。

点睛：物块和圆盘保持相对静止，一起做匀速圆周运动，靠静摩擦力提供向心力，方向指向圆心；若转盘加速转动，物块所受摩擦力的方向不指向圆心，这点需要学生注意。

3. 游乐园中旋转木马是一个老少皆宜的游戏项目：如图所示旋转木马运动稳定后，其在绕转轴匀速转动的同时，还相对各自所在的竖直钢杆上下运动，给人以骑马驰骋的感觉。
