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,
6、 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 w

14、 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 isnt harmful, then why are we constantly rubbing our eyes when were looking
15、 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, isnt the cause.

34、学生用书P401(单独成册) 阅读理解A(2020安徽重点中学模拟)One of the easiest ways to stop the spread of disease is to simply wash your hands. 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
35、 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
36、at teaching kids good handwashing habits and encouraging kids to wash their hands with soap appropriately and regularly.“Its such a simple habit to do, but the fact is that people arent doing it, and its resulting in actual deathswhich is shocking. So, we decided to come up with a fun method，” said
37、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 dont spend enough time washing it off, the colors remain on the childrens hands. Issar said it makes sure that children take enough time to wash the
38、ir 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 theyre drawing on their hands.

This may explain why so many people dream about fightin
51、g 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 minute
52、s, and elephants every 2 hours.

55、 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。7Which animal may dream most frequently?AR
56、ats. BDogs.CCows. DElephants.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。8How does the author develop his passage?ABy making comparisons. BBy using figures.CBy telling stories. DBy 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
57、grunting noises, messages from her brain to the large muscles in her legs are blocked, so she cant 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。 七选五(2020南昌高三段考)Public SpeakingPublic speaking can be defined as the act of making a speech in front of a group of listeners.The types of public
58、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
59、 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 pe
60、rson 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
61、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 carefull
62、y 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 a
63、lso 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._AIt needs to be used clearly.BThese speeches mark special occasions.CThe important thing to watch about is not to put
64、 in too much information.DThe key of perfecting anything is through practice, including public speaking.EThey can also end it with a special message and encourage the audience to ask questions.FKnowing how public speaking is done is a key part in understanding the importance of it.GThus, the speaker
65、 needs to know how to deliver their speech to fulfill the audiences 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。1C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。2D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.i
66、s 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。3A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。4G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，
67、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。5E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.
