AIn recent years, terms like “going green” and “eco-friendly” have become buzz words on talk shows, commercials a nd product packaging. The term “eco-friendly” has been used for so many different products and practices.Eco-friendly Car RaceCan you imagine a car racer is so eco-friendly that its tyres are made from potatoes, its body is created from hemp (大麻) and rapeseed oil and it runs on fuel made from wheat and sugar beet(甜菜)? Theone-seater racing car called Eco One is built by experts from Warwick University, who hope that Eco One will be adopted by the automotive industry. It is sold at $ 51,000.Pollution-sensitive DressDon’t be caught outside unaware of pollution levels in the air. The pollution-sensitive EPA Dress by Stephanie Sandstrom notices pollution in the air accordingly. This dress -- which is actually quite pretty -- looks like you pull it from the bottom of the dirty laundry pile when the air is dirty. It might protect your health by advising you t o stay indoors for the day, but it won’t do you any favor if you’re meeting with clients.Eco-friendly UmbrellaTraditional umbrellas come with a fixed surface. Although it is changeable, you cannot replace it easily. This eco-friendly design is more flexible. It is actually only an umbrella skeleton(骨架)without any surface, which can be folded, so you can put anything such as newspapers, plastic bags or whatever you want to serve as the protecting surface.Eco-friendly Moss(苔藓)CarpetIt is said that walking on fresh grass increases your blood circulation. The Moss Carpet, created by Nguyen La Chanh, looks at getting the grass to your feet. The mat includes ball moss, island moss and forest moss. The humidity(湿度)of the bathroom ensures that it grows well. An d that’s why you need to place it there and not anywhere else.11. According to Paragraph 1, we can find Eco One _____.A. can seat one passenger and one driverB. can’t be afforded by the public at presentC. is mainly made from some kinds of plantsD. will take the place of the traditional car industry12. Why is EPA Dress designed?A. To advise people to stay at home as often as possible.B. To stop people from meeting their clients if necessary.C. To make women look pretty even in the polluted air.D. To keep users informed of the polluted levels in the air.13. Compared with traditional umbrellas, the Eco-friendly Umbrella _____.A. is changeableB. hasn’t any surfaceC. can be foldedD. is made of newspapersBA new “paparazzi-proof” scarf has got heatedly welcomed since launched. A new “pap arazzi-proof” scarfcould be a game-changer for celebrities who prefer to shy away from thestage light. The ISHU scarf is the creation of Dutch-born fashionentrepreneur Saif Siddiqui and is designed to “give people their right toprivacy back”. A host of celebrities including Cameron Diaz, singer JoeJonas, Bayern Munich footballer Jerome Boateng and music producerMajor Lazer have worn the ISHU after it was spotted at London FashionWeek last year.It works by reflecting the light back into a camera, eff ectively becoming “invisibility clothes” for celebrities who don’t want their photo s taken. Anyone wearing the scarf is protected from mobile flash photograph, with the fashion accessory’s fabric(附件结构)effectively blocking out any unwanted pictures, althoug h it doesn’t stop no-flash photographs from being taken.The 28-year-old Siddiqui was inspired while visiting family in Amsterdam in 2009 when his friends attempted to take a photo of him using an iPhone in front of some bikes. “He noticed that the bike’s reflectorcarried the flash of his mobile camera in a way that confused the faces of his friends in the picture.” the ISHU website explains. “He immediately realiz ed that if developed into the right product, this feature would be an ideal solution for his friends and is now available to the public who want to keep their private moments in public private. “Saif put together a team of experts who dug into the science of light and reflection, and how to blend technology with fashion.”He told Decoded Magazine: “The ISHU scarf effectively allows an individual to control what pictures and videos are taken of him. “There are no more unwanted pictures and videos on Snapchat, Instagram, or Facebook! Everyone carries a phone with them nowadays that has an amazing camera. So, it all made sense to me.” More ISHU products are set to launch in August, with mobile phone cases set to launch in the next few weeks. The ISHU is currently sold out but you can pre-order it online for£289.14. The underlined phrase “shy away” in paragraph 1 means .A. hideB. shameC. takeD. fly15. Why did Saif design the “paparazzi-proof” scarf?A. To help protect people’s privacy.B. To make a rich profit from the celebrities.C. Because the scarf is to get a heated welcome.D. To dig into the science of light and reflection.16. How did Saif get the creative idea of producing scarves?A. He was inspired by the photographs of bike.B. He was inspired when his friends attempted to take a photo of him.C. He was inspi red when finding his friends’ picture was not ideal.D. He was inspired while cycling with his family members.17. Which of the following statement might be true?A. The paparazzi-proof scarf can prevent any unwanted pictures being taken.B. There might be fewer unwanted pictures and videos on internet.C. ISHU will be only used to effectively control pictures taken.D. Customers will mainly buy ISHU products online.CSome colors people see late at night could cause signs of clinical(临床的)depression. That was the finding of a study that builds on earlier study findings. They show that individuals who live or work in low levels of light overnight can develop clinical depression. Doctors use the word “clinical depression” to describe severe form of depression. Signs may include loss of interest or pleasure in most activities, low energy levels and thoughts of death or suicide.In the new study American investigators designed an experiment that exposed hamsters(仓鼠)to different colors. The researchers chose hamsters because they are nocturnal which means they sleep during the day and are active at night.The animals were divided into four groups. One group of hamsters was kept in the dark during their night-time period. Another group was placed in front of a blue light a third group slept in front of a white light while a fourth was put in front of a red light.After four weeks the researchers noted how much sugary water the hamsters drank. They found that the most depressed animals drank the least amount of water.Randy Nelson heads the Department of Neuroscience at Ohio State University. He says animals that slept in blue and white light appeared to be the most depressed. “What we saw is that these animals didn’t show any sleep uneasiness at all but they did mess up biological clock genes and they did show depressive sign while if they were in the dim(微弱)red light they did not.”He notes that photosensitive(感光)cells in the eyes have little to do with eyesight. He says these cellssend signals to the area of the brain that controls what has been called the natural sleep-wake cycle.He says there’s a lot of blue in white light. This explains why the blue light and white light hamsters appear to be more depressed than the hamsters seeing red light or darkness.18. Researchers use hamsters in the experiment because __________.A. they are similar to humans in dealing with colorsB. they are easy to observe and studyC. they are sensitive to colors like human beingsD. they are active at night and sleep during the day19. What sign shows that the hamsters are being depressed?A. Their energy level becomes low.B. They don’t sleep well.C. Their eyesight becomes worse.D. They drink less sugary water.20. __________ tends to cause hamsters to be depressed.A. Dim lightB. Blue lightC. Red lightD. Darkness21. What can help people who work late at night to avoid being depressed?A. Equipping their computer screens to put it more in the reddish light.B. Not being exposed to dim red light when using computers.C. Living or working in low levels of light overnight.D. Going to see doctors of clinical depression regularly for help.DBody language is a broad term for several forms of communication using body movements or gestures, instead of, or as a complement to, sounds, verbal language, or other forms of communication. In turn, it is one category of paralanguage, which describes all forms of human communication that are not language.Paralanguage including body language has been extensively studied in social psychology. In everyday speech and popular psychology, the term is most often applied to body language that is thought to be involuntary, but in fact the distinction between voluntary and involuntary body language is often blurred: a smile or a wave may be given either voluntarily or involuntarily, for example.V oluntary Body Language is less commonly discussed because it seems unproblematic. It refers to movement, gestures and poses intentionally made by the person: smiling, hands, imitating actions, and generally making movements with full or partial intention of making them and a realization of what they communicate.The relation of body language to animal communication has often been discussed. Human paralanguage may represent a continuation of forms of communication that our non-linguistic ancestors already used, or it may be that it has been changed by co-existing language. Some species of animals are especially skilled at detecting human body language, both voluntary and involuntary: this was the reason for trying to teach the chimpanzee Washoe American Sign Language rather than speech and perhaps the reason why the Washoe project was more successful than some previous efforts to teach apes how to dance.Body language is a product of both genetic and environmental influences. Blind children will smile and laugh even though they have never seen a smile. The ethnologist(文化人类学者)Iraneus Eibl-Eibesfeldt claimed that a number of basic elements of body language were universal across cultures and must therefore be fixed action patterns under instinctive(本能的)control. Some forms of human body language show continuities with communicative gestures of other apes, though often with changes in meaning. More refined gestures, which vary between cultures (for example the gestures to indicate“yes” and “no”), must obviously be learned or modified through learning, usually by unconscious observation of the environment.22. Which of the following diagrams shows the right relationship _______?①= language ②= paralanguage ③= body language ④= verbal languageB. C. D.23. According to the passage, the reason why the Washoe project was a success may be that ______.A. the chimpanzee Washoe can be taught speechB. apes can be taught how to danceC. Washoe can understand body language wellD. numbers of basic elements of body language are same in different cultures24. Why does the author take the gestures to indicate “yes” and “no” for an example?A. to give us the meaning of the two gesturesB. to tell us continuities of some fixed action patternsC. to show environmental influences of the sign languageD. to indicate genetic effects of the body language25. The last two paragraphs mainly talk about _______.A. origins of the body languageB. cultural influencesC. what the body language isD. relationships between body languages and animal communications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。

2024年广东省佛山市顺德区14校高二下学期联考物理试卷(解析版)

2024年佛山市顺德区高二第二学期14校联考物理试卷一、单选题1. 控制噪声的基本原则是设法将噪声的能量转化为其他形式的能量,如图所示是一种利用薄板消除噪声的方法。

将薄板安放在框架上,并与框架之间留有一定的空气层,当声波入射到薄板上时,引起板的振动。

由于板本身的内耗使振动的能量转化为热量。

改变薄板的材料和空气层的厚度,可有效消除不同频率的噪声。

下列说法正确的是()A. 薄板振动频率始终与入射声波的频率相等B. 随着入射声波频率的增加,薄板振动的幅度一定增大C. 当噪声停止后,薄板振动频率仍等于原噪声频率,但振幅减小D. 该系统可有效消除的噪声频率范围在其可调节的共振频率之间【答案】D【解析】【详解】A.薄板振动稳定后的频率与声波频率相同,初始没有达到稳定时不同,A错误;B.薄板的振幅在入射声波的频率与薄板的故有频率相同时,二者共振,振幅最大,其它频率的声波,薄板的振幅可能会增大,也可能会减小,B错误;C.当噪声停止后,薄板振动逐渐不稳定至振动停止,此时频率与原噪声频率不同,C错误;D.只有当噪声频率范围在系统可调节的共振频率之间,二者可以产生干涉波纹,达到消除噪声的目的,D正确。

故选D。

2. 光头强在远处看见树在摇晃,走近一看,发现是熊大靠在树干上正在挠痒痒。

那么下列说法正确的是()A. 树木摇晃的频率就是熊大来回踏动的频率B. 熊大来回蹭动得越快,树木晃动就越大C. 熊大蹭树的位置越靠下,树木震动的越快D. 熊大蹭树的位置越靠上,树木震动的越快【答案】A【解析】【详解】ACD.树木的摇晃是受迫振动,振动的频率等于驱动力的频率,即树木摇晃的频率就是熊大来回踏动的频率,故A正确,CD错误;B.当驱动力的频率与树木的频率越接近时,树木的振幅就越大,因为树木的固有频率未知,无法确定当驱动力频率增大时树木的振幅,故B错误。

故选A。

3. 关于光的薄膜干涉,下列说法正确的是()A. 薄膜干涉说明光具有波动性,相机镜头表面镀了一层透光膜是利用衍射原理B. 观察薄膜干涉条纹时应在入射光的同一侧观察,牛顿环干涉属于等厚干涉C. 在薄膜干涉现象中,波谷和波谷叠加处,光将减弱,出现暗条纹D. 单色光的干涉条纹是彩色的,白光的干涉呈黑白相间的条纹【答案】B【解析】【详解】A.薄膜干涉说明光具有波动性,相机镜头表面镀了一层透光膜是利用干涉原理,选项A错误;B.观察薄膜干涉条纹时应在入射光的同一侧观察,牛顿环干涉属于等厚干涉,选项B正确;C.在薄膜干涉现象中,波谷和波谷叠加处,光将加强,出现明条纹,故C错误;D.单色光的干涉条纹是单色的,白光的干涉呈彩色相间的条纹,故D错误。

There was a pool at the YMCA offering exactly the opportunity. My mother continually warned against it, and kept fresh in my mind the details of each drowning in the river. But the YMCA pool was safe.I had a childhood fear of water. This started when I was three years old and my father took me to the beach. The huge waves knocked me down and swept over me.The pool was quiet. I was afraid of going in all alone, so I sat on one side of the pool to wait for others. Then came a big boy. He yelled, “Hi, how’d you like to be ducked?” With that he picked me up and threw me into the deep end. I landed in a sitting position, and swallowed water. But I was not frightened out of my wits—when my feet hit the bottom, I would make a big jump to come out of the surface. It seemed a long way down. I gathered all my strength when I landed and made what I thought was a great spring upwards. Then I opened my eyes and saw nothing but water. I tried to yell but no sound came out. I went down, down, endlessly.When I came to consciousness, I found myself lying on the bed in the hospital.I never went back to the pool. I avoided water whenever I could. This misadventure stayed with me as the years rolled by. It deprived (剥夺) me of the joy of boating and swimming. Finally, I decided to get an instructor. Piece by piece, he built a swimmer. Several months later, the instruction was finished, but I was not. Sometimes the terror would return.This went on until July. I swam across the Lake Wentworth. Only once did the terror return. When I was in the middle of the lake, I put my face under and saw nothing but bottomless water. I laughed and said, “Well, Mr. Terror, what do you think you can do to me?”I had conquered my fear of water.11.What was the author’s original fear of water caused by?A.His poor skill in swimming.B.His mother’s warning of drowning.C.An outing to the beach with his father.D.An unpleasant memory of the pool.12.Why was the author not scared to death when he was thrown into the water?A.He knew how to swim in the pool.B.He felt that the YMCA pool was safe.C.He was waiting for others to save him.D.He came up with an idea to go upwards.13.What does the author probably mean by expressing “but I was not” in paragraph 5?A.He was still a poor swimmer.B.He hadn’t overcome the fear yet.C.He hadn’t finished the instruction yet.D.He was not satisfied with the swimming training.14.Which of the following is the best title for the text?A.Goodbye, Mr. Terror B.Hello, Childhood FearC.A Swimming Adventure D.My Passion for SwimmingGrown-ups are often surprised by how well they remember something they learned as children but have never practiced ever since. A man who has not had a chance to go swimming for years can still swim as well as ever when he gets back in the water. He can get on a bicycle after many years and still ride away. He can play catch and hit a ball as well as his son. A mother who has not thought about the words for years can teach her daughter the poem that begins “Twinkle, twinkle, little star” or remember the story of Cinderella or Goldilocks and the Three Bears.One explanation is the law of overlearning, which can be stated as follows: Once we have learned something, additional learning trials increase the length of time we will remember it.In childhood we usually continue to practice such skills as swimming, bicycle riding, and playing baseball long after we have learned them. We continue to listen to and remind ourselves of words such as “Twinkle, twinkle, little star” and childhood tales such as Cinderella and Goldilocks. We not only learn but overlearn.The multiplication tables (乘法口诀表) are an exception to the general rule that we forget rather quickly the things that we learn in school, because they are another of the things we overlearn in childhood.The law of overlearning explains why cramming (突击学) for an examination, though it may result in a passing grade, is not a satisfactory way to learn a college course. By cramming, a student may learn the subject wellenough to get by on the examination, but he is likely soon to forget almost everything he learned. A little overlearning, on the other hand, is really necessary for one’s future development.15.How does the author explain the law of overlearning?A.By using examples.B.By making a comparison.C.By setting down general rules.D.By presenting research findings.16.What do we know about being able to use multiplication tables?A.It’s a skill to deal with math problems.B.It’s a special case of cramming.C.It’s a result of overlearning.D.It’s a basic step towards advanced studies.17.What is the author’s opinion on cramming?A.It leads to failure in college exams.B.It’s helpful only in a limited way.C.It increases students’ learning interest.D.It’s possible to result in poor memory.It’s surprising how much simple movements of the body can affect the way we think. Using expansive gestures with open arms makes us feel more powerful, crossing your arms makes you more determined and lying down can bring more insights.So if moving the body can have these effects, what about the clothes we wear? We’re all well aware of how dressing up in different ways can make us feel more attractive, sporty or professional, depending on the clothes we wear, but can the clothes actually change cognitive performance or is it just a feeling?Adam and Galinsky tested the effect of simply wearing a white lab coat on people’s powers of attention. The idea is that white coats are associated with scientists, who are in turn thought to have close attention to detail.What they found was that people wearing white coats performed better than those who weren’t. Indeed, they made only half as many errors as those wearing their own clothes on the Stroop Test (one way of measuring attention). The researchers call the effect “enclothed cognition,” suggesting that all manner of different clothes probably affect our cognition in many different ways.This opens the way for all sorts of clothes-based experiments. Is the writer who wears a fedora more creative? Is the psychologist wearing little round glasses and smoking a cigar more insightful? Does a chef’s hat make the restaurant food taste better?From now on I will only be editing articles for PsyBlog while wearing a white coat to help keep the typing error count low. Hopefully you will be doing your part by reading PsyBlog in a cap and gown (学位服). 18.What is the main idea of the text?A.Body movements change the way people think.B.How people dress has an influence on their feelings.C.What people wear can affect their cognitive performance.D.People doing different jobs should wear different clothes.19.What did Adam and Galinsky’s experiment test the effect of clothes on?A.Their wearers’ insights.B.Their wearers’ attention.C.Their wearers’ movements.D.Their wearers’ appearance.20.How does the author sound in the last paragraph?A.Formal.B.Hopeful.C.Academic.D.Humorous.四、其他21.将下列几个部分(A、B、C、D和E)按题号排序,构成一个符合逻辑的完整语篇。
