I thought I would be natural for climbing. I was always an athlete and naturally good at sports. So, I didn’t understand why I was so bad at rock climbing.I went to the rock gym and climbed all the time, and everyone kept telling me “just climb more and you’ll get better.” “Well, however, nothing I did was working. It felt like the harder I worked at it, the less progress I was actually making.After a while, I even started hating any climber who was stronger and better than me---especially the climbers who made it look so easy.A fter a long time, I started making friends with some of the most experienced climbers around… professionals(专业人员)and full-timers. In fact, I felt so comfortable with them that one afternoon I just came out and simply asked for help. There is a saying, “If you want a shortcut to success, find someone who is successful and ask them to show you how to get there.” It is true in just a few short months. I learned far more from these climbing professionals than what I had learned during the previous(之前的) years of struggle on my own. My climbing changed…my strength, skills, mental toughness, formwork, confidence, everything.I was no longer the average climber that no one knew. I discovered that climbing like the experts is more about working smarter, not harder(no training 7 days a week). What I discovered is so simple that, looking back now, I realized the biggest thing holding me back from being a better climber and having more fun doing it…was Me!1．According to the passage, we can learn that _____.A．the writer had no gift for rock climbingB．the writer didn’t get the skill of rock climbing at firstC．the writer didn’t work hard at rocking climbingD．the writer thought too much of himself2．The writer once hated other good rock climbers because _____.A．they did n’t want to teach him B．they always made fun of himC．he envied their good skills D．he began to dislike rock climbing3．Which of the following statements is TRUE?A．The writer never lost heart when he studied rock climbing.B．It took several years for the writer to become a good climber.C．The writer felt uncomfortable staying with those climbing experts.D．The writer hated to learn from those better than him.4．What the writer wants to tell us is that _____A．the more you climb, the better you’ll be.B．mends always make you progressC．the way of learning is important D．it’s not necessary to work hardC15、Many people take running as a way to keep fit. They like to run in hot weather and enjoy the feeling of being wet through with sweat while running. Cold weather during winter months, with low temperatures and freezing cold winds, may keep many people from running in the open air.However, a new study shows that the drop in temperature is a good reason to run. In fact, running in cold weather helps improve o ne’s performance. Many runners might find it easier to run in winter than in hot weather.Lower temperatures reduce stress on the body. When you run in cold weather, your heart rate is lower. And the body needs less water on a cold day than in warm weather because dehydration levels are lower in winter than in warmer conditions.John Brewer is a professor of applied sports science at ST. Mary’s University in London. For this study, he and other researchers put a group of people into a room where summer and winter weather conditions are recreated. The test subjects, were asked to run 10,000 meters under both conditions and their biological measurements were recorded and studied.From the study, every movement runners make produces heat. The heat can be really damaging unless the body can lose it. One way in which people lose heat is by sweating. The body loses heat through droplets of sweet. The body also loses it by transporting the blood to the surface of the skin and it puts more stress on the heart, particularly in hot conditions because it’s much harder to lose heat when the outside environment is warm. As the result shows running in hot temperatures results in 6 percent higher heart rates.When running in cold conditions, the body does not have to work hard to pump blood to the skin surface. Therefore, it requires less energy. The most important thing for people who run in cold conditions is to wear the right clothing. Keep as dry as possible when exercising in low temperatures. Wear mittens on your hands instead of gloves. Wear more than one layer of clothing to keep sweat away from your skin. So don’t let winter weather keep you indoors. Simply get ready for the low temperatures and start running.1．Why do most people dislike running outdoors in winter?A．It’s too cold. B．It’s hard to run.C．It’s too easy to sweat. D．It’s bad for the heart rate.2．What does the underline word ＂dehydration＂in Paragraph 3 means the loss of ______from the body.A．water B．heat C．stress D．blood3．Why did John Brewer make a group of people run in a room?A．It was easier to be reduce stress.B．It was easier to produce heat.C．It was easier to recreate different weather conditions.D．It was easier to record their biological measurements.4．What should people wear while running in cold winter?A．A hat. B．Gloves.C．More clothing. D．More than one layer of clothing.5．What’s the purpose of the passage?A．To tell people not to run in summer.B．To describe how runners run in winter.C．To encourage people to run outdoors in winter.D．To compare the advantages of running in winter and in summer.D16、Who is the greatest teacher in Chinese history? Many people would think of Confucius, whose birthday was September 28. Although he lived over 2,000 years ago, people still remember and respect him today.Confucius lived in the Kingdom of Lu, which lies in Shandong Province. He lived during the Spring and Autumn Period. He had a hard childhood. His father died when he was only three. His mother brought him up. As a child, he had to work to help his mother, but young Confucius didn’t give up studying. He visited many famous teachers and learned music, history, poetry and sports.Later, he became a teacher and started the first public school in Chinese history. At that time only children from noble families could go to school, but Confucius believed everyone should go to school if they wanted to learn. He had about 3,000 students in his lifetime.Today, people still follow Confucius’ lessons. He told us that we all have something valuable to be learned. “When I am with three people, one of them must be better than me in some areas. I choose their good qualities and follow them.”He also taught us that thinking is very important in study. “All study but no thinking makes peopl e puzzled（困惑的）. All thinking but no study makes people lazy.”Confucius is not only a great teacher, but also a famous thinker with wise thoughts about the world and society. His most important teachings are about kindness and good manners（举止）.” A person s hould be strict with himself, but be kind to others.” he said.1．Today we still remember Confucius because .A．he lived a poor life in his childhoodB．he had wise thoughts about the world and societyC．he traveled with his students from state to stateD．he lived during the Spring and Autumn Period2．Confucius learned music, history, poetry and sports as a child.A．by teaching himself at home B．with the help of his motherC．by going to school D．by visiting many famous teachers3．The underlined w ord “noble” in Paragraph 3 has the closest meaning to .A．poor B．bright C．rich D．cute4．The correct order of the following sentences is .① Confucius worked to help his mother as a child.② Confucius had about 3,000 students in his lifetime③ C onfucius’ father died.④ Confucius started the first public school in Chinese history.A．③①④②B．②③④①C．①③②④D．④③①②5．Which of the following is NOT mentioned in the passage?A．All study but no thinking makes people puzzled.B．No one has something worthy to be learned.C．All thinking but no study makes people lazy.D．A person should be strict with himself, but be kind to others.E17、Right at this minute, a red car is flying above you in space. How can a car go into space? US company SpaceX’s heavy-lift rocket the Falcon Heavy sent it there on February6, 2018, CNN reported.This was the Falcon Heavy’s first successful test launch. It was described as the start of “a new space age”.The Falcon Heavy is the world’s most powerful rocket. It can carry things we ighing 64,000 kilograms into space, theAtlantic reported. This means the Falcon Heavy could send about 1,000 passengers into space once.However, the rocket isn’t just for taking cars into space. Space X and its founder Elon Mask,46,want to restart task to the moon and help humans land on Mars.In September 2017 in Australia, Musk shared his plans to put a million people on Mars in the next 40 to 100 years. It seems like a dream. But he added it could be just a few years away.The red car actually shows M usk’s dream of exploring space. He put a model personin the driver’s seat. The model wears a spacesuit and listens to the song Space Oddity written by UK rock star David Bowie. Musk said the car and its passenger will travel in space for millions of years.

However, not everyone is a fan of them. On Sept. 6, an article described some male stars as too effeminate.This came after CCTV was criticized for inviting several young male stars to perform on First Class for the New Semester，an educational TV show for primary and secondary school students, which aired 5days earlier. After that,many parents left comments online, saying the stars in the show had a bad influence on their children.The popularity of effeminate male stars is partly down to the influence of Japanese and South Korean pop culture, an expert told China Daily. However, the “femininity” of males isn't a recent social phenomenon. In fact, being effeminate was popular among Chinese men centuries ago.Indeed, the debate about effeminate male stars has been going on for a while. In July, a Hong Kong singer said during the singing reality show Sing! China that he feels tired of seeing effeminate male stars. “It isn't that they're not good, but we should discover ourselves.”He said during the show.His opi nion was shared by a Chinese director. “Some young actors are feminine and they should be more manly,” he said.Deng Xiquan, head of the Y outh Research Institute at the China Youth and Children Research Center, believes such a phenomenon is completely natu ral.“It will be replaced by a new youth culture at some stage. If a man has feminine beauty, this doesn't mean that he lacks responsibility,” Deng told China Daily. Deng's opinion was echoed by the People's Daily.“A man's strength should be judged on the b asis of their inner qualities - not their phyical apperance,” it wrote.1．First Class for the New Semester aired on_________A．Sept.6 B．Sept.3 C．Sept.2 D．Sept.12．From the third paragraph we can know that_________A．the popularity of effeminacy appeared in Japan firstB．young, effeminate male stars are popular in South KoreaC．in China, being effeminate was popular hundreds of years agoD．Chinese experts don't think effeminate male stars are popular3．Which of the following is RIGHT about the Hong Kong singer?A．He doesn't like effeminate male stars.

Many of my friends showed photos of themselves riding bikes, especially during the weekend in natural parks, and I can see people logging in and out of shared bike apps.But are people really drawn to the idea of exercise and green transportation all of a sudden?I tried Mobike last week, and I didn’t especially like it. I think the first generation（代）Mobikes, the ones without baskets, are designed for athletes. They are very hard to ride, and the seat is not adjustable（可调节的）. Then, I tried the yellow ofo bikes. They are easier to ride than Mobikes, but they don’t usually have baskets, and you need to enter the password by hand, instead of scanning a QR code and having the lock open automatically （自动地）like with Mobikes.I agree that there are shared bikes on the road. They have saved me a lot of time, and on beautiful, clear days, I do enjoy riding them outside the city. But from what I’ve seen in my WeChat moments, people have been giving them endless compliments（赞赏）, while I saw their disadvantages.In my experience, there has never been an agreed decision on anything in public opinion. It makes me wonder whether these people really like riding shared bikes or are just saying this to agree with others.When I asked them one by one, a friend named Li Ling secretly told me she tried the bikes to fit in. She doesn’t like bikes and finds Beijing’s roads too terrible for bike riding. But recently, the only way to hang out with her friends is riding out of town together. To join in social（社会的）activities, she had to pick up bike riding again.Zhou Hai, another friend of mine, told me that he started talking about and forwarding information on shared bikes to appear fashionable to friends.

It’s true that shared bikes .A. always have the color of yellowB. has drawn many people’s attentionC. are designed only for athletesD. are easy to find but hard to ride（）2. The writer enjoys the shared bikes because .A. they don’t have a basketB. they are easy to rideC. they have saved him much timeD. they have passwords（）3. From the passage, we can learn that .A. Li Ling likes the shared bikes because Beijing’s roads are too busyB. Li Ling likes riding the shared bikes to improve her healthC. Zhou Hai started paying attention when his friends are riding togetherD. Zhou Hai started talking about shared bikes to keep himself fashionable（）4.

中考数学重点专题复习考点11 二次函数-备战2022年中考数学必考点与题型全归纳(原卷版)

考点11 二次函数二次函数是非常重要的函数，年年都会考查,总分值为18~20分，预计2022年各地中考还会考，它经常以一个压轴题独立出现，有的地区也会考察二次函数的应用题，小题的考察主要是二次函数的图象和性质及或与几何图形结合来考查。

1、二次函数的概念：一般地，形如y =ax 2+bx +c （a ，b ，c 是常数，a ≠0）的函数，叫做二次函数．2、二次函数解析式的三种形式（1）一般式：y =ax 2+bx +c （a ，b ，c 为常数，a ≠0）．（2）顶点式：y =a （x –h ）2+k （a ，h ，k 为常数，a ≠0），顶点坐标是（h ，k ）．（3）交点式：y =a （x –x 1）（x –x 2），其中x 1，x 2是二次函数与x 轴的交点的横坐标，a ≠0． 3、二次函数的图象及性质解析式二次函数y =ax 2+bx +c （a ，b ，c 是常数，a ≠0）对称轴 x =–2ba 顶点（–2b a ，244ac b a-）a 的符号a >0a<0图象开口方向开口向上开口向下最值当x =–2b a 时，y 最小值=244ac b a- 当x =–2b a 时，y 最大值=244ac b a- 最点抛物线有最低点抛物线有最高点增减性当x <–2ba 时，y 随x 的增大而减小；当x >–2b a 时，y 随x 的增大而增大当x <–2ba 时，y 随x 的增大而增大；当x >–2b a时，y 随x 的增大而减小4二次函数平移遵循“上加下减，左加右减”的原则，据此，可以直接由解析式中常数的加或减求出变化后的解析式；二次函数图象的平移可看作顶点间的平移，可根据顶点之间的平移求出变化后的解析式．5、二次函数与一元二次方程的关系1）二次函数y =ax 2+bx +c （a ≠0），当y =0时，就变成了一元二次方程ax 2+bx +c =0（a ≠0）． 2）ax 2+bx +c =0（a ≠0）的解是抛物线y =ax 2+bx +c （a ≠0）的图象与x 轴交点的横坐标． 3）（1）b 2–4ac >0⇔方程有两个不相等的实数根，抛物线与x 轴有两个交点；（2）b 2–4ac =0⇔方程有两个相等的实数根，抛物线与x 轴有且只有一个交点；（3）b 2–4ac <0⇔方程没有实数根，抛物线与x 轴没有交点． 6、二次函数的综合 1）函数存在性问题解决二次函数存在点问题，一般先假设该点存在，根据该点所在的直线或抛物线的表达式，设出该点的坐标；后用该点的坐标表示出与该点有关的线段长或其他点的坐标等；最后结合题干中其他条件列出等式，求出该点的坐标，然后判别该点坐标是否符合题意，若符合题意，则该点存在，否则该点不存在． 2）函数动点问题（1）函数压轴题主要分为两大类：一是动点函数图象问题；二是与动点、存在点、相似等有关的二次函数综合题（2）解答动点函数图象问题，要把问题拆分，分清动点在不同位置运动或不同时间段运动时对应的函数表达式，进而确定函数图象；解答二次函数综合题，要把大题拆分，做到大题小做，逐步分析求解，最后汇总成最终答案．（3）解决二次函数动点问题，首先要明确动点在哪条直线或抛物线上运动，运动速度是多少，结合直线或抛物线的表达式设出动点的坐标或表示出与动点有关的线段长度，最后结合题干中与动点有关的条件进行计算．考向1

(2019·浙江绍兴中考)Have you ever seen a car without a driver? It sounds crazy, but these computer-driven driverless cars will soon be filling roads near you. Companies like Google and Tesla have been designing and testing these cars, and the technology is there.So how? The cars have sensors(感应器) all around which can find other cars and objects in the road. Road signs are read by cameras, and satellite navigation systems(卫星导航系统) are used so the car knows how to get where you want to go. All you have to do is type in the address! Finally, a central computer system takes in all the information that it receives from the sensors and cameras and works out when to speed up, stop and turn.Sound like your idea of heaven(天堂)? Sitting back, looking out of the windows and even watching a film or reading a book while‘driving’ would be possible with this new technology. You wouldn't have to worry about remembering directions to where you're going. In addition, computers would also drive more safely than people—they would obey the rules and have quicker action times when in dangerous situations.However, there are many drawbacks of driverless cars. Computers would have difficulties making ethical(道德的) decisions: if a child ran into the road, would the computer choose to hit the child or turn suddenly and potentially kill the car's passengers? Moreover, I personally find driving fun—I'd miss never driving a carmyself. There would also be many other decisions to be made—should children, or drunk people, be allowed in a driverless car by themselves? Or would there need to be a person with a driving license in the car at all times?I'm not certain I'd want a driverless car—but it's only a matter of time before they'll become more affordable and popular on our roads.1．When using a driverless car, you need only ．A．read the road signs carefullyB．check the camerasC．put the address into the computerD．remember the directions2．The third paragraph mainly tells us about the of driverless cars. A．instructionsB．standardsC．advantagesD．tests3．The underl ined word “potentially” i n Paragraph 4 means ．A．possiblyB．successfullyC．especiallyD．naturally4．What's the writer's opinion about future driverless cars?A．They'll cause more accidents.B．They'll be less expensive.C．They'll use less energy.D．They'll run much faster.二、词汇运用A．用方框中所给单词的适当形式填空。

Mary, didn’t you ever wonder what you’re really like? Go and make a list of everything she said and mark the points that are true. Pay no attention to the o ther things she said.”I did as he told me and to my surprise, I discovered that about half the things were true.I brought the list back to my dad. He refused to take it. “That’s just for you,” he said. “You know better than anyone else the truth about yo urself. When something said about you is true, you’ll find it will be helpful to you. Don’t shut your ears. Listen to them all, but hear the truth and do what you think is right.”Many years have passed. The situation often appears in my mind.

I also enjoy news and humor shared on soci al media,” Said Ou Wei, 14, from Hongling Middle School in Shenzhen.

I promised that I’d be very careful. One of them wanted to come with me but I asked her to stay with another friend who needed help with her baby.I walked out of the hotel and started making my way to the car. At the crossing, a black car stopped and a man came out with an umbrella. Before I knew what was happening, he walked right through me and told me he’d escort (护送) me. Although I refused, he insisted (坚持) that he would.During our walk, he kept telling me to walk slower, as the ground was wet. When we got to the car-park, I thanked him and he went away. I did not get his name and can hardly recognize (认出) him now. Did he stop for me? I’ll never know. So how did I pay it forward?

They are exercises done in water. They are also called water exercises,. It is believed that aqua exercises can help people burn more fat than exercises on dry land .There are two main types of aqua exercises.First, aqua jogging. We must wear a special belt which can protect us and help us floating as we run in the water. Although we are in water, we should run very hard as if we were jogging on dry land.Aqua jogging can protect our joints(关节)and at the same time make our muscles (肌肉) work hard.The famous actress, Jennifer Aniston, is reported to aqua jog for fifteen minutes every day. Now there are many aqua jogging clubs and classes all over the UK.Second, aqua Tai Chi .Tai Chi on land is an ancient Chinese exercise designed to improve balance, reduce stress and help people to relax. Aqua Tai Chi can do this better. Peter Chou , who has established a Tai Chi school , says, “Ta i Chi is about fluidity(流动性) and relaxation. For thousands of years, experts have been asking people to imagine being in water when they are practicing Tai Chi, so why not actually put them in water? When their hands and feet move slowly through water, the people can experience what fluidity feels like both mentally and physically, and understand this exercise better. The water can also make them slower and more relaxed.”People will need an understanding of Tai Chi and should be able to perform some of the simple movements on land before trying aqua Tai Chi. It is not suitable for beginners because they need to see how the teachers’ hands and feet are moving, which is not easily done underwater.根据材料内容选择最佳答案，并将其标号填入题前括号内。
