But a lot of teenagers studying overseas still __53__ taking sightseeing or relaxation trips in their new homes.Sunny Miao, 15, had a good time traveling to South Dakota with her host family from Missouri. They also visited Mount Rushmore, another tourist site in the state.Her 18-year-old host brother Justin Dussold enthusiastically introduced her to a huge depiction of four US __54__ carved (雕刻) into the face of a mountain, including George Washington and Abraham Lincoln. “I’ve benefited a lot from this spring outing by gaining new knowledge about the country,” Miao said.There are exceptions, though.

Drivers get 5 yuan per ride, with five rides allowed each day. Didi offers no more than 20 yuan per ride to both passengers and drivers, Beijing Evening News reported on March 5.By the end of February, the number of users on both Didi and Kuaidi was more than 50 million, Beijing Times reported.Popular as the taxi-calling apps may be, a series of problems have emerged. Due to the large numbers of orders being placed at the same time, the taxi-calling apps often crash. In order to claim as much as possible, some drivers constantly check the apps to grab more taxi c alls, even while they’re driving. “It greatly distractsdrivers’ attention, thus causing a threat to road safety,” Beijing Review commented. “As drivers prefer taking taxi orders from apps, they will overlook senior citizens and those standing on the stree t,” Beijing Review continued.Some cities have taken measures to regulate the market. Beijing said last month that each taxi is only allowed to be linked with one taxi-calling app, China Daily reported. In Shanghai, drivers will be banned from using these apps during rush hour starting on March 1st. The city has also decided to include these taxi apps in its own taxi-calling service platform.55.What’s the main purpose of the first paragraph?A.

Drivers will possibly be unwilling to do a favour for those in trouble without reservation.D. A driver will be banned from being connected with two taxi-calling applications.BPROCEDURES FOR HANDLING CHEMICAL SPILLS (泄露) AND LEAKSChemical spills or leaks can be broken down into two basic types: simple spills, which you can clean up yourself, and complicated spills, which require outside assistance.If your spill meets any of the following conditions, it is a complicated spill.• A person is injured.•The identity of the chemical is unknown.•Multiple chemicals are involved•The chemical is highly poisonous.•The spill/leak occurs in a “public space” such as a corridor.•The spill/leak has the potential to spread to other parts of the building such as through the ventilation (通风) system.•The clean-up procedures are not known or appropriate materials are not readily available.•The clean-up requires a respirator(呼吸器) to be worn and no personnel have been trained and fit-tested in accordance with the campus Respiratory Pr otection Program.•The spill/leak may endanger the environment by reaching waterways or outside ground, or by going down a drain.If none of the above conditions are met, the spill is defined as a simple spill. You may clean up simple spills in reference to Chapter 6 of the Chemical Safety Guide. For further assistance, call Division of Research Safety (DRS) at 333-2755. How to Report a Complicated Spill1)Leave for a safe location, and remind others to get rid of it.2)Dial 9-911 from a campus phone.3)Tell the operator you are calling to report a chemical spill at the Universityof Illinois.4)Have the following information ready.•Name of chemical•Quantity spilled•Location of spill (Full building name and room number)•Number of people injured or splashed•If applicable, the occurrence of a fire or explosion•Your name and phone number5)Have someone knowledgeable about the chemical spilled meet the fire departmentat the main entrance to your building. Take an MSDS of the chemical, if it is readily available.58.Which of the following situations can be regarded as a simple spill?A. Some spilled liquid causes a fire in the building.B. Yellow and green gases are leaking from the storage room.C. An unknown red chemical is found on the corridor floor.D. A researcher spills his milk all over the lab floor.59.According to the safety instructions, upon discovering a complicated spill oncampus, people should ______.A. put on a respirator as soon as possibleB. refer to Chapter 6 of the Chemical Safety GuideC. get away from the spill and report it to authoritiesD. call Division of Research Safety at 333-275560.The main purpose of the material above is to ______.A. inform people of the dangers of various chemical spillsB. introduce complicated spills and necessary measures to deal with themC. encourage students to join the campus Respiratory Protect ion ProgramD. compare simple spills with complicated spillsCONCE, Neil Armstrong’s son was asked about his father in an interview. Among all the wonderful qualities of the former US astronaut, who went to the moon in 1969, one bad one was mentioned —he said it was difficult to watch a sci-fi movie with his dad, because he would keep complaining about how unrealistic their visions of space were.”Indeed, sci-fi movies are usually far-fetched. Even the Oscar-winning Gravity, which was described as “the most realistic space movie ever” by Forbes, is not 100 percent faithful to reality.So let’s do a fact-check with former US astronaut Scott Parazynski, who told Vulture News his thoughts about Gravity.First of all, the danger of space debris(残骸) is very real. There are currently more than 600,000 pieces of debris larger than 1 cm orbiting Earth and they pose a great risk to spacecrafts. However, in the movie, astronauts can see the debris coming and quickly seek shelter. In reality, debris can travel at 20 times the speed of sound, which means that if you can see it, it’s a lready too late to hide.Another error in the movie is when Matt Kowalsky, the male astronaut played by George Clooney, lets go of the hand of his female partner, Ryan Stone (played by Sandra Bullock), and flows away into space. “Kowalski wouldn’t have flo wn away when Stone let go of his hand. Instead, he would have just stayed floating in that spot.” says Parazynski.In the movie, Stone travels from the Hubble Telescope to the International Space Station and then to the Chinese Space Station Tiangong, where she finds an escape vehicle to take her back to Earth. But this is actually the biggest error in the movie. Space stations travel in different orbits, and they travel quickly. “They’re basically speeding bullets relative to one another,” said Parazynski.“And it would be physically impossible to get from one to the other.”But in the end, all of these “mistakes” add drama to the plot and make the movie more fun to watch. After all, “this is not a documentary(纪录片),” as Alfonso Cuarón, director of the movie, told . “It is a piece of fiction.”61.The underlined word “far-fetched” in the second paragraph probably means______.A. difficult to understandB. unlikely to be trueC. easy to mislead peopleD. full of unbelievable plots62.Which of the following situations agrees with the laws of physics in spaceaccording to the article?A. Astronauts collect flying space debris.B. Astronauts wear only T-shirts under their spacesuits.C. Astronauts stay floating where they are after they part with a spaceship.D. Astronauts perform a space walk from one orbit to another.63.We can infer from the article that ______.A. directors of sci-fi movies usually don’t care much about minor detailsB. Scott Parazynski doesn’t think Gravity is a good movieC. the shooting of space documentaries and sci-fi movies involve totally different skillsD. Alfonso Cuarón believes that sci-fi movies don’t need to be totally faithful to reality64. What’s the author’s attitude towards the science fiction movie?A. objectiveB. subjectiveC. negativeD. indifferentSection C (6%)Directions: Read the passage carefully. Then answer the questions or complete the statements in the fewest possible words.The “standard of living” of any country means the average person’s share of the goods and services which the country produces. A country’s standard of living, therefore, depends on its capacity to produce wealth. “Wealth” in this sense is not money, for we do not live on money but on things that money can buy: “goods” such as food and clothing, and “services” such as transport and entertainment.A country’s capacity to produce wealth depends upon many factors, most of which have an effect on one another. Wealth depends to a great extent upon a county’s natural resources. Some regions of the world are well supplied with coal and minerals, and have a fertile soil and a favorable climate; some regions possess none of them. The USA is one of the wealthiest regions of the world because of its natural resources while the Sahara Desert produces the least wealth.Next to natural resources comes the ability to turn them to use. China is perhaps as rich as the USA in natural resources, but suffered for many years from civil and external(外部的)wars, and for this and other reasons was unable to develop her resources. Sound political conditions and freedom from foreign invasion enable a country to develop its natural resources peacefully and steadily, and to produce more wealth than another country equally well served by nature but less well ordered.A country’s standard of living does depend not only upon the wealth that is produced and consumed within its own borders, but also upon what is directly produced through international trade. For example, Britain’s wealth in other agricu ltural products would be much less if she had to depend only on those grown at home. Trade makes it possible for her surplus(过剩的)manufactured goods to be traded abroadfor the agricultural products that would otherwise be lacking. A country’s wealth is, therefore, much influenced by its manufacturing capacity, if other countries can be found ready to accept its manufactures.(Note: Answer the following questions and complete the statements in NO MORE THAN TEN WORDS.)65.What is a country’s “standard of living” defined as?_________________________________________________________.66.Why did China fail to develop her natural resources as planned?_________________________________________________________.67.The agriculture products would not be enough in Britain without________________________.第II卷(共25分)IV.

有人认为,当下城镇化进程加快,人员流动加大,三口之家普遍存在,“差序格局” 所依赖的“地缘”与“血缘”关系受到很大的冲击,因此今天的中国社会已经不适合用“差序格局”来定义了,但也有人不以为然。

请根据你对“差序格局”的理解,谈一谈你的观点,并简要阐述理由。

三、现代文阅读①千百年来,“偏见”一词一直是带贬义的。

在人们心目中,偏见就意味着错误,是思想认识的大敌,因此,人人都不应当有偏见。

偏见是如此不受欢迎,以至于各个领域的思想家无不以扫除偏见为己任,以便达到无偏见的认识。

在人们心中存在着一种根深蒂固的观念:偏见是应当消除而且是可以消除的。

②进入现代社会,随着社会交往的扩大和各种相关理论特别是哲学真理观的发展,传统的偏见观开始动摇,人们日益意识到偏见是普遍存在的。

美国科学史家萨顿经过一番考察后指出:“即使是掌握最伟大真理的英雄,也不能完全摆脱偏见的束缚。

”美国哲学家桑塔亚那则提出:人的见解是受利益驱动的,而利益上的差异必然要导致偏见的产生,因此,“理智是充满偏见的”。

对传统偏见观抨击得最激烈的,当推德国著名哲学家伽达默尔。

(共15分)读书意在___________⑴我在讲了《庄子心得》之后,有人问我,“我离婚了,日子困难,该读什么书”,“我要高考了,我应该看哪段话”。

这个问题孔子和庄子都回答不了,他们那个时代不知道现在的生活。

读书并不是像有一本《百科全书》放在那里,我们一查就豁然开朗了。

⑵但读书可以使安定的生活锦上添花,可以是惶惑时候的雪中送炭,可以在遭遇困顿的时候,让我们的内心镇定而勇敢。

当一个死刑犯人还在读书,那么他读书的用处肯定不是求职,可能就是为了带一份安定告别生命。

⑶读书给了我们精神生活上的储备。

我把自己读书的过程,称为老牛吃草。

年轻或有空的时候,我把自己懂的、不懂的书全部吞进去。

当自己在成长过程中遇到坎坷、真正想到用的时候,就调出来。

这就像反刍。

说起来,我读书,读的数量不是最多,读的质量也不是最精。

2021-2022学年上海高一数学下学期满分全攻略第01讲 正弦余弦正切余切(核心考点讲与练)练习版

第01讲 正弦、余弦、正切、余切(核心考点讲与练)1.角的概念的推广(1)正角,负角和零角.用旋转的观点定义角,并规定了旋转的正方向,就出现了正角,负角和零角,这样角的大小就不再限于00到3600的范围.(2)象限角和轴线角.象限角的前提是角的顶点与直角坐标系中的坐标原点重合,始边与x 轴的非负半轴重合,这样当角的终边在第几象限,就说这个角是第几象限的角,若角的终边与坐标轴重合,这个角不属于任一象限,这时也称该角为轴线角.(3)终边相同的角,具有共同的绐边和终边的角叫终边相同的角,所有与角α终边相同的角(包含角α在内)的集合为{}Z k k ∈⋅+=,360 αββ. (4)角α在“ 0到 360”范围内,指 3600<≤α.2.弧度制:弧长等于半径的弧所对的圆心角叫做1弧度的角.用“弧度”作为单位来度量 角的单位制称为弧度制.弧度:长度等于半径的弧所对的圆心角的大小 (1) 角度制与弧度制换算关系:180π︒=弧度3.扇形弧长与面积:记扇形的半径为r ,圆心角为α弧度,弧长为l ,面积为s ,则有4.单位圆:单位圆泛指半径为1个单位的圆.本章中,在平面直角坐标系中,特指出以 原点为圆心、以1为半径的圆为单位圆.5.正弦、余弦、正切及余切的定义:在平面直角坐标系中,将角α的顶点与坐标原点o 重合,始边与x 轴的正半轴重合,在角α的终边上任取异于原点的一点p (x ,y ),就有sin y r α=;cos x r α=;tan yx α=;cot x yα=; 6.任意角的正弦、余弦、正切、余切(1)平方关系:22sin cos 1αα+=(2)商数关系:sin tan (cos 0)cos αααα=≠;cos cot (sin 0)sin αααα=≠; (3)倒数关系:tan cot 1αα⋅=;注意:1) “同角”的概念与角的表达形式无关,如:13cos 3sin 22=+αα,2tan 2cos2sinααα=. 2)上述关系(公式)都必须在定义域允许的范围内成立.3)由一个角的任一三角函数值可求出这个角的其余各三角函数值,且因为利用“平方关系”公式,最终需求平方根,会出现两解,因此应尽可能少用,若使用时,要注意讨论符号.考点一:象限角与终边相同的角【例1】(2020·上海市奉贤区奉城高级中学高一期末)下列各组角中,两个角终边不相同的一组是( ) A .43-与677B .900与1260-C .120-与960D .150与630【例2】(2020·上海市莘庄中学高一月考)终边在y 轴负半轴上的角的集合为___________________【例3】(2020·上海市金山中学高一期中)2019角是第_______象限角. 【例4】(2020·上海浦东新区·高一期中)与4π角终边重合的角的集合是________ 【例5】(2021春•静安区试题)★☆☆☆☆【例6】(2021宝山区校级试题)★★☆☆☆【巩固练习】1.(2021春•黄浦区校级试题)★☆☆☆☆2.(2021春•普陀区校级试题)★☆☆☆☆3.(2020浦东新区校级试题)★★☆☆☆4.在0与360范围内,找出与下列各角终边相同的角,并判断它们是第几象限角?(1)120- (2)640 (3)95012'-考点二:弧度制【例1】.把角6730'化为弧度制.【例2】若两个角的和是1弧度,此两角的差是1,试求这两个角.【例3】指出下列各角所在的象限:(1)517π; (2)π623-.【例4】(教材练习)★☆☆☆☆【例5】(2019春•黄浦区校级试题)★☆☆☆☆【巩固练习】1.已知弧度数为2的圆心角所对的弦长也是2,则这个圆心角所对的弧长是( )A .2B .C .D .2.一钟表的分针长10 cm ,经过35分钟,分针的端点所转过的长为:( )A .70 cmB .cm C .()cmD . cm 3.与角 1825-的终边相同,且绝对值最小的角的度数是___,合___弧度。
