One of the highlights (精彩部分) of this musical event is the street carnival (嘉年华), which is free to all.

What do we know about the Edinburgh International Festival from the article?A. It started in 1947.B. It’s held at the Royal Mile.C. It’s free to Scottish people.D. It takes place in July every year.2. Which is the largest arts festival in the world?A. The Edinburgh International Festival.B. The Edinburgh Festival Fringe.C. The Edinburgh International Book Festival.D. The Edinburgh Jazz and Blues Festival.3. According to the passage, what can visitors do at the Edinburgh Jazz and Blues Festival?A. They can try on different costumes.B. They can join a singing competition.C. They can take part in a street carnival.D.

The astonishing variety of facial features helps people recognize each other and is important to the formation of complex societies. So is the face’s ability to send emotional signals, whether through an unconscious reddening of face or a false smile. People spend much of their waking lives, in the office and the courtroom as well as the bar and the bedroom, reading faces, for signs of attraction, trust and cheat. They also spend plenty of time trying to dissimulate.Technology is rapidly catching up with the human ability to read faces. In America, facial recognition is used by churches to track prayers’attendance; in Britain, by shopkeepers to spot past thieves. This year Welsh police used it to arrest a suspect outside a football game. In China, it verifies the identities of ride-hailing (网约车) drivers, permits tourists to enter attractions and lets people pay for things with a smile. Apple’s new iPhone is expected to use it to unlock the home screen.Compared with human skills, such applications might expand steadily in scale. Some breakthroughs, such as flight or the Internet, obviously transform human abilities; facial recognition seems merely to encode them. Although faces are peculiar to individuals, they are also public, so technology does not, at first sight, intrude on something that is private. And yet the ability to record, store and analyse images of faces cheaply, quickly and on a vast scale promises one day to bring about major changes to our understanding of privacy, fairness and trust.Start with privacy. One big difference between faces and other biometric (计量生物学的) data, such as fingerprints, is that they work at a distance. Anyone with a phone can take a picture for facial-recognition programs to use. FindFace, an app in Russia, compares snaps of strangers with pictures on VKontakte, a social network, and can identify people with a 70% accuracy rate. Even if private firms are unable to join the dots between images and identity, the state often can. Photographs of half of America’s adult population are stored in databases that can be used by the FBI. Law-enforcement agencies now have a powerful weapon in their ability to track criminals, but at enormous potential cost to citizens’ privacy.1. What does the underlined word “dissimulate” in paragraph 1 mean?A. Hide emotions from others.B. Make known to the public.C. Act in disregard of laws.D. Become friends with others.2. What does the underlined word “them” in paragraph 3 refer to?A. applicationsB. breakthroughsC. human abilitiesD. human skills3. What kind of changes might be discussed in the following paragraphs?A. Safety and first aid.B. Social services.C. Finance and trade.D. Fairness and trust.4. What’s the best title for the passage?A. Benefits resulting from facial breakthrough.B. Facial Recognition: nowhere to hide.C. The power of human faces.D. Technologies concerning facial recognition.（3）The taxi driver was a man in his late thirties. He picked me up and 1 me to my place. I usually like to have brief 2 with people no matter where I come upon them and this situation was no different.I started by asking him how 3 was. He told me briefly that his business was just4 but the cost of gas was really hurting his5 line. We then got around to discussing the job environment.

【语文暑假作业】新高二年级第二周第3天拓展阅读(名家作品)+专题训练(信息类文本阅读)
_______月_______日星期_______ 姓名：_______名家散文——王安忆《南陌复东阡》2024年高考新课标II卷现代文阅读Ⅱ的材料出自作家徐则臣的散文《放牛记》。
《放牛记》是徐则臣真实的人生经历自述，感情真挚、语言幽默。
在回忆性视角下，作家并没有将放牛当作一件苦差事，反而认为放牛满足了自己儿时的“英雄梦”。
【作品导读】一座城市，往往有它独特的性情气质，人身处其中，尤其是生于斯长于斯，无不受到它濡染、浸润。
上海旧里弄里，南陌复东阡，纵横交错，看似混杂凌乱，却有着作家王安忆美好难忘而又忧患备尝的童年记忆，海派作家王安忆的《南陌复东阡》，堪为一篇隽永深沉的美文，作家以女性特有的敏感、细腻，描写里弄风物，建筑格局，叙写少小记忆，书写缱绻情思，意到笔随，蕴含着关于童年、成长、故乡、城市、人生的诸多情思。
娓娓道来中，有人生成长普遍而深切的体验，有怀旧伤逝的无奈，有“向之所欣，俯仰之间，已为陈迹”的唏嘘感慨，有沧海桑田、时过境迁及所蕴含的独特的生命体验。
【文本研读】南陌复东阡几乎是一整个九十年代，我都是从忧患中度过。
母亲多病，一年里总有一度住在医院。
病房在新建大楼的高层，可算得上那一片街区的制高点。
走廊上有一扇侧窗，望出去是一片旧式弄堂的连绵屋瓦，夕阳的光里面，飞翔着黑色的斑点，是回家的鸽群。
写景纯用白描，寥寥几笔，即勾勒出上海里弄的初印象，俨然市井、民俗生活老照片，使人如身临其境。
“回家的鸽群”，既是眼前实景，也暗含着作者对“心灵的故乡”的思归之情，文章开篇即奠定了一种怀旧伤逝的淡淡的哀伤情绪。
许多时间，是面了这扇窗过去，有时和我妈妈，有时只我自己。
心里有一种伤痛，不知是被谁伤着了，分明是来自于无边无际的不可抗力。
于是，又为这暂时的相守感到安宁。
（不可抗力，是指生老病死，不可抗拒；“安宁”是指能与母亲相守，弥足珍贵。
）以上写作者陪母亲看病时，在医院的高楼上看到的上海弄堂的情形及感受，引出下文对上海弄堂的回忆。
