I would like to point out that many people believe that graffiti is an art form that can benefit our public spaces just as much as sculptures, fountains, or other more accepted art forms.‎ People who object to graffiti usually do so more because of where it is, not what it is. They argue that posting graffiti in public places is considered an illegal act of property damage. But the location of such graffiti should not prevent the images themselves from being considered real art.‎ I would argue that graffiti is the most important public art form. Spray paint is a medium unlike any other. Through graffiti, the entire world has become a canvas(画布). These works of art dotting the urban landscape are available, free of charge, to everyone who passes by.‎ To be clear, I do not consider random words or names sprayed on stop signs to be art. Plenty of graffiti is just vandalism, pure and simple. However, there is ‎ 27‎ also graffiti that is breathtaking in its complex detail, its realism, or its creativity. It takes great talent to create such involved designs with spray paint. Are these creators not artists just because they use a can of spray paint instead of a paintbrush?‎ To declare that all graffiti is vandalism, and nothing more, is an overly simplistic statement. Furthermore, graffiti is not going anywhere, so we might as well find a way to live with it and enjoy its benefits. One option could be to make a percentage of public spaces open to graffiti artists. By doing this, the public might feel like part owners of these works of art, rather than just the victims of a crime.‎ ‎【解题导语】　本文是一篇议论文。文章通过论述涂鸦与公共空间的关系，进而探讨涂鸦是否为艺术。作者认为判断其是否为艺术应该根据涂鸦的质量而非存在的地方。‎ ‎1．Mark Turin apparently believes that graffiti ________．‎ A．is not an art form B．is too simple to be considered art C．can only sometimes be considered a work of art D．should be restricted to places where it is allowed A　解析：细节理解题。根据第一段第一句“In Mark Turin’s article ‘Protecting Our Public Spaces’ in issue 14, he claims that ‘all graffiti(涂鸦) is vandalism(故意破坏财物的行为), pure and simple, and offers no benefit to our public spaces’．”可知，Mark Turin显然认为涂鸦不是一种艺术形式。‎ ‎2．The author argues that graffiti ________．‎ A．is the only art form that is free B．is best viewed on public walls rather than canvases C．provides more public benefits than sculptures do D．should be judged on artistic qualities rather than places D　解析：细节理解题。根据对全文的整体理解，尤其是第二段最后一句“But the location of such graffiti should not prevent the images themselves from being considered real art.”可知，作者认为评价涂鸦应该根据其艺术品质而不是其所在地点。‎ ‎3．The author concludes his passage by ________．‎ A．restating his position B．questioning the magazine C．offering an answer to the matter D．identifying the benefits of graffiti 27‎ C　解析：推理判断题。根据最后一段的内容尤其是“One option could be to make a percentage of public spaces open to graffiti artists.”可推知，作者是通过提供一个解决办法来结束文章的。‎ B ‎(2020·济南模拟)We humans love to stare into our smart devices. We gaze for hours—about 10 hours and 39 minutes a day—at our computers, smartphones, tablets and televisions. Is all this staring bad for us? It might be, mainly because as we stare at our devices we are exposing ourselves to blue light.‎ Blue light is a type of electromagnetic(电磁的) radiation with a very short wavelength that produces a high amount of energy. While it’s true that light can damage our eyes under certain circumstances, there’s no scientific evidence suggesting that blue light is harmful to our eyes. But many people still think it is, which is why bluelightblocking glasses are so popular. So do the glasses work?‎ ‎“Everyone is very concerned that blue light may be causing damage to the eye, but there’s no evidence that it may be causing serious damage，” Dr. Rahul Khurana, clinical spokesman for the American Academy of Ophthalmology, told Business Insider.‎ Blue light exposure is nothing new. In fact, the sun is the largest source of blue light. Moreover, blue light is also present in LED light. But if blue light isn’t harmful, then why are we constantly rubbing our eyes when we’re looking at our screens? The answer is eyestrain (眼疲劳): More than 60 percent of people experience eye problems associated with digital eyestrain. And blue light, it seems, isn’t the cause. Instead, our eyes are so strained because most of us blink less when we stare at our digital devices. So if eyestrain is the issue, bluelightblocking glasses are probably of little use.‎ ‎【解题导语】　该文主要探讨了蓝光是否对我们的眼睛有害的问题。‎ ‎4．What do we know about blue light?‎ A．It is a kind of nuclear radiation.‎ B．It has the shortest wavelength.‎ C．It may come from electronic devices.‎ D．It consumes a great deal of energy.‎ C　解析：推理判断题。根据第一段最后一句“It might be, mainly because as we stare at our devices we are exposing ourselves to blue light.”可推知，电子设备会发出蓝光。‎ 27‎ ‎5．What causes the popularity of bluelightblocking glasses?‎ A．Evidence of their benefits to eyes.‎ B．Belief in blue light’s harmful effect.‎ C．Widespread use of smart devices.‎ D．Scientific understanding of blue light.‎ B　解析：细节理解题。根据第二段中的“there’s no scientific evidence suggesting that blue light is harmful to our eyes. But many people still think it is, which is why bluelightblocking glasses are so popular.”可知，防蓝光眼镜流行的原因是人们认为蓝光会对眼睛有害。‎ ‎6．What can be inferred from Paragraph 4?‎ A．Blue light exposure is hardly avoidable.‎ B．Eye problems are not easy to deal with.‎ C．Blue light may connect with tired eyes.‎ D．Rubbing eyes makes people strained.‎ A　解析：推理判断题。根据第四段的前三句“Blue light exposure is nothing new. In fact, the sun is the largest source of blue light.

Twenty seconds of handwashing with soap and water can reduce illnesses and save lives. But, many people, especially children, do not have good handwashing habits. One problem is that children do not wash their hands often enough or long enough. Children may think that it is a tiresome thing to do.‎ To help handle this problem, two businesswomen from India created a product to turn handwashing into a fun activity. Amanat Anand and Shubham Issar created a tool called SoaPen, aimed at teaching kids good handwashing habits and encouraging kids to wash their hands with soap appropriately and regularly.‎ ‎“It’s such a simple habit to do, but the fact is that people aren’t doing it, and it’s resulting in actual deaths—which is shocking. So, we decided to come up with a fun method，” said Issar.‎ As the name suggests, SoaPen is a pen made out of soap. The children draw on their hands with the soap pen and then wash the drawing off. If they don’t spend enough time washing it off, the colors remain on the children’s hands. Issar said it makes sure that children take enough time to wash their hands. This may be especially helpful in a classroom. Often a teacher does not have the time to make each child wash his hands properly.‎ Kids actually wash their hands for the proper amount of time because they’re drawing on their hands. To obliterate the drawing, they actually wash their hands instead of just going under water and, you know, a onesecond wash and off.‎ Good news is that the school children in Mumbai, India, will soon most likely wash their hands after handling a pet. Issar and Anand stated that SoaPen to be created everywhere will help promote good habits through handwashing in the city across the globe.‎ 27‎ ‎【解题导语】　本文是一篇说明文，介绍了SoaPen。SoaPen是一款画笔样式的液态洗手产品，孩子们可用它在手上涂抹然后洗手，如果他们没有花足够的时间洗手，颜色会留在他们的手上，这会让洗手充满乐趣。‎ ‎1．Why does SoaPen come into existence?‎ A．To cure kids of some kinds of diseases.‎ B．To teach kids the importance of soap.‎ C．To help kids wash their hands correctly.‎ D．To make money from children consumers.‎ C　解析：细节理解题。依据第一段中的“One problem is that children do not wash their hands often enough or long enough.”可知，问题是孩子们洗手的频率不够或洗手的时间不够长；再联系第二段中的“aimed at teaching kids good handwashing habits and encouraging kids to wash their hands with soap appropriately and regularly”可知，发明SoaPen的目的在于让孩子们养成良好的洗手习惯，由此可知选项C正确。‎ ‎2．Which of the following does Issar agree with?‎ A．Handwashing is anything but little.‎ B．SoaPen is designed for classrooms.‎ C．Some teachers ignore kids’ health in school.‎ D．Kids don’t know the right way of handwashing.‎ A　解析：细节理解题。依据第三段Issar的话“It’s such a simple habit to do, but the fact is that people aren’t doing it, and it’s resulting in actual deaths”可知，有些人因为没有养成良好的洗手习惯而死亡，由此可知，洗手习惯对我们的健康是至关重要的，故选A项。‎ ‎3．What does the underlined word “obliterate” in paragraph 5 mean?‎ A．Show.　　　　　　　 B．Reserve.‎ C．Learn. D．Remove.‎ D　解析：词义猜测题。依据该段的“Kids actually wash their hands for the proper amount of time because they’re drawing on their hands.”可知，孩子们需要用足够的时间去洗手才能洗掉SoaPen的图案，由画线词后的内容可知，为了消除SoaPen留在手上的痕迹，孩子们不再只是匆匆洗手了。由此可知，画线词与remove意思相近，故选D项。‎ ‎4．What can we learn from the last paragraph?‎ A．SoaPen has become popular worldwide.‎ B．The inventors think SoaPen has a bright future.‎ C．SoaPen has been applied in Mumbai schools.‎ D．Kids’ health should be paid more attention to.‎ 27‎ B　解析：推理判断题。依据该段的“Issar and Anand stated that SoaPen to be created everywhere will help...across the globe.”可知，发明者表示SoaPen将在世界各地生产，这也会促进在全球推广好的洗手习惯，她们对SoaPen的未来有信心，由此可知选项B正确。‎ B ‎(2020·东北三省四市二模)You can’t see your sleeping pet’s brain waves, but its behavior can tell you when your cat might be dreaming. If you watch closely, you’ll see that as she falls asleep, her breathing becomes slow and regular with her body still. She has entered the first stage of sleep, called slowwave sleep. After about 15 minutes you’ll notice a change in her breathing. Her eyes move under her closed lids, her paws twitch(抽动) and she flicks(轻拂) an ear. She has entered dreaming. Although she twitches and makes little grunting noises, messages from her brain to the large muscles in her legs are blocked, so she can’t run about. She is in a state of “sleep paralysis(麻痹)”．‎ Michel Jouvet, a French scientist, interrupted their sleep paralysis. Even though they were completely asleep, the dreaming cats began to run for balls that Jouvet couldn’t see and arched their backs at unseen enemies. He figured he was watching them act out their dreams! Obviously, the dreaming cats seemed to be practising important cat skills: following, pouncing, and fighting.‎ In another study, Matt Wilson recorded rats’ brain waves while they learned mazes. One day, he left the brainwaverecording machine on while the rats fell asleep. The pattern of brain waves in the sleeping rats matched the pattern from the maze so closely that Wilson could figure out exactly which part of the maze each rat was dreaming about!‎ Many researchers now think that in both people and animals, one purpose of dreams is to practise important skills and figure out recent learning. This may explain why so many people dream about fighting and escaping, skills that were probably important to our ancestors, and why dreaming affects our ability to learn.‎ Do all animals dream? From looking at the brain waves of sleeping animals, how often animals dream seems to be tied to body size. Cats dream about every 15 minutes, mice every 9 minutes, and elephants every 2 hours. And though cows and horses usually sleep standing up, they only dream when lying down.‎ 27‎ ‎【解题导语】　本文是一篇说明文。研究发现，动物和人类一样，也经常会做梦，梦的内容常常跟学习重要的技能和弄清最近学习的东西相关；体型越小的动物，做梦的频率越高。‎ ‎5．What does Michel Jouvet find in his study?‎ A．The dreaming cats are in a state of body paralysis.‎ B．The dreaming cats often practise their important skills.‎ C．The eyes of dreaming cats move while bodies are still.‎ D．The legs of the dreaming cats can’t move.‎ B　解析：细节理解题。根据第二段尾句“Obviously, the dreaming cats seemed to be practising important cat skills：following, pouncing, and fighting.”可知，这些做梦的猫似乎在练习重要的猫科动物技能：跟随、猛扑和打斗。据此可知，Michel Jouvet在研究中发现，睡梦中的猫经常训练重要的技能，故B项正确。‎ ‎6．What can you know about dreaming from the passage?‎ A．Dreaming a lot can help humans learn more.‎ B．Learning mazes is the basic skill for cats to learn.‎ C．Rats often dream to work out their recent learning.‎ D．Fighting and escaping are not important skills for ancestors.‎ C　解析：推理判断题。根据第四段第一句“Many researchers now think that in both people and animals，one purpose of dreams is to practise important skills and figure out recent learning.”可知，许多研究人员现在认为，无论是人还是动物，做梦的一个目的都是练习重要的技能，并弄清最近学习的东西；据此可推知，老鼠经常通过做梦来弄清楚最近学习的东西，故C项正确。‎ ‎7．Which animal may dream most frequently?‎ A．Rats. B．Dogs.‎ C．Cows. D．Elephants.‎ A　解析：细节理解题。根据尾段可知，动物做梦的频率跟它们的体型大小有关，猫每15分钟做一次梦，老鼠每9分钟做一次梦，大象每2小时做一次梦。据此可知，老鼠做梦的频率最高，故A项正确。‎ ‎8．How does the author develop his passage?‎ A．By making comparisons. B．By using figures.‎ C．By telling stories. D．By showing facts.‎ D　解析：写作手法题。根据第一段倒数第二句“Although she twitches and makes little grunting noises, messages from her brain to the large muscles in her legs are blocked, so she can’t run about.”并结合全文其他内容可知，文中列举了大量事实来说明动物做梦的现象，从而组织文章，故D项正确。‎ 27‎ 七选五 ‎(2020·南昌高三段考)‎ Public Speaking Public speaking can be defined as the act of making a speech in front of a group of listeners.‎ The types of public speaking are deliberately structured with three general purposes: to inform, to persuade and to entertain the audience. An informative speech has a purpose to inform, or give knowledge to its audience. 1.________ For persuasive speech, the speaker would try to change the mindset, perception, or behavior of the audience for their own good. Thus, the speaker needs to look for common ground with the audience and try to relate to what they might agree on. The last type is a ceremonial speech. It tends to be less formal and more personal than the other types of speeches. No matter how well you know the person you are giving speech to, try not to say bad things about them, even if it is meant to be a joke.‎ ‎2．________ Sparing some time to practice will help build confidence and help determine how long the presentation will last. Aside from it, knowing who the audience will be is quite necessary. Try to get as much information as possible regarding this particular area related to the audience. Knowing the “battlefield” in advance will give the speakers a huge advantage. ‎ Language is the main aspect a speaker needs to pay attention to while giving a speech. 3.________ A speaker needs to choose their words carefully and make it clear to the audience what they mean. Often, when given a speech, the audience look to the speaker to give them something new and useful. 4.________ Language and delivery(演讲方式) alone will not be sufficient if the speaker does not have the body language. The movement and gesture of a speaker also affect the audience. While closing the speech or presentation, speakers can restate their main points, just to remind the audience of the important things that have been said. 5.________‎ A．It needs to be used clearly.‎ B．These speeches mark special occasions.‎ C．The important thing to watch about is not to put in too much information.‎ D．The key of perfecting anything is through practice, including public speaking.‎ E．They can also end it with a special message and encourage the audience to ask questions.‎ F．Knowing how public speaking is done is a key part in understanding the 27‎ ‎ importance of it.‎ G．Thus, the speaker needs to know how to deliver their speech to fulfill the audience’s expectation.‎ ‎【解题导语】　本文介绍了公共演讲的几个类型以及做好演讲所需注意的事项。‎ ‎1．C　解析：从结构上看，第二段首先介绍了公共演讲的三种目的；接下来对这三种目的分别介绍了其对应的演讲类型以及注意事项，空处位于介绍informative speech这种类型之后，应是说明它的注意事项，故C项表述不要输入太多的信息符合语境。其中information是关键提示词。‎ ‎2．D　解析：本空是段首句。本段讲述了公共演讲的两个注意事项。下文“Aside from it...is quite necessary.”讲的是第二个注意事项：要提前了解观众是谁。接着进一步阐述了注意事项。空后讲的是多加练习对于演讲的好处，由此可推知，空处应是第一个注意事项，并且与空后一句中的“practice”相呼应，故选D。‎ ‎3．A　解析：本空是段中句。空前一句是说语言是演讲中需注意的主要方面。空处应是对其进行进一步的说明，关键词是Language，A项中的It指的就是Language，且根据空后的“make it clear to the audience”可知，A项“它(语言)需要使用得很清楚”符合语境。‎ ‎4．G　解析：本空是段中句。空前讲的是观众期待演讲者能给他们新的有用的东西，故G项“因此，演讲者需要了解如何发表他们的演讲来满足观众的期待”与空前一句构成逻辑上的因果关系，故G项符合语境。‎ ‎5．E　解析：本空是段尾句。空前讲的是演讲者可以重申要点，提醒观众所讲的重要事情来结束演讲，空处应是叙述另一种结束方式，故E项符合语境。‎ 语法填空 ‎(2020·陕西摸底检测)Recently researchers have had a finding 1.____________ singing in groups could have a positive impact on reducing 2.____________(anxious) and depression.
