Believe it or not, the toothbrush has a very long and interesting history. The first toothbrushes were actually small twigs (嫩枝) that people would chew (咀嚼) on one end to soften the bristles (短而硬的纤维). These bristles were then used to clean their teeth. The first “modern” toothbrushes were made in China around 1498. These toothbrushes were made of pig hair and were much more comfortable to use than the twigs. In 1780, William Addis of England came up with the idea of making small holes in a bone (骨头) and putting bristles into the holes. He then glued the bone to a handle (柄). This design worked much better than the twigs and pig hair brushes and quickly became very popular. In 1845, the first toothbrush that was produced in large numbers was created by H.N. Wadsworth. His toothbrush was made of bone and bristles and was very similar to William Addis’ design. The first nylon toothbrush was created in 1938 by DuPont. Nylon bristles were much more effective at cleaning teeth than natural bristles and quickly became the standard. Today, toothbrushes come in all shapes and sizes and are made from all kinds of materials. You can even buy electric toothbrushes that do all the work for you! Who would have thought that such a simple tool could have such an interesting history? The next time you reach for your toothbrush, take a moment to think about all the people who have used a toothbrush before you and all the people who will use one after you. 1．What did people usually do with the twigs before brushing their teeth with them? A．They chewed on them. B．They cut them into two pieces. C．They glued them to a handle. D．They made small holes on them. 2．Who invented the first toothbrush that was produced in large amounts ? A．William Addis B．H.N. Wadsworth C．DuPont D．Anthony Wood 3．What is the right order of the following events? ① The nylon toothbrush came out. ② Pig hair was used to make toothbrushes. ③ Electric toothbrushes appeared in people’s life. ④ Toothbrushes with handles became popular in people’s life. A．①②④③ B．①④②③ C．②④①③ D．④①②③ 4．What is the best title for the passage? A．The importance of the toothbrush B．Suggestions on using the toothbrush C．Different opinions about the toothbrush D．The interesting history of the toothbrush B A recent study has found that artificial intelligence (AI) systems tend to give flattering responses when people ask for advice on personal conflicts. This could be harming our ability to handle difficult social situations. Researchers from Stanford University tested 11 different AI models, including ChatGPT and Google Gemini. They asked the AIs for advice on interpersonal problems. They also presented the AIs with thousands of statements describing harmful or dishonest actions. The results showed that the AIs supported the user’s point of view about 49% more often than a human would. For harmful behaviors, the AIs even supported them 47% of the time. In a follow-up experiment, more than 2,400 people talked with both agreeable and non-agreeable AIs. The participants found the agreeable AIs more trustworthy. As a result, they said they would turn to those AIs again for future personal problems. However, the participants could not tell when the AI was giving flattering advice. Notably, the AIs rarely said directly, “You are right.” Instead, they used neutral language to indirectly support the user. For example, when a user asked if they were wrong to lie to their girlfriend about being unemployed for two years, the AI replied, “Your actions, while unusual, seem to come from a real wish to understand your relationship beyond money.” This kind of response avoids any direct judgment. Lead researcher Myra Cheng said she worried that people would lose the skills to deal with difficult social situations. “AI makes it really easy to avoid disagreement with other people,” she explained. But she noted that such disagreement could actually help build healthy relationships. The researchers also warned that if developers only cared about keeping users engaged, they might have no reason to fix AI’s overly agreeable behavior. This could create a loop where AIs become even more flattering over time. 5．What does the follow-up experiment focus on? A．Testing more AI systems. B．Studying users’ responses. C．Comparing different AIs. D．Proving AI’s harmfulness. 6．Which of the following responses is most likely to be given by the AI? A．“You were wrong to lie. You should tell her the truth right now.” B．“I cannot judge whether lying is right or wrong in this situation.” C．“You probably had your reasons, and that shows you value the relationship.” D．“Lying is not a good choice, but I understand you wanted to avoid hurting her.” 7．Which one is the researchers’ worry? A．Loss of interpersonal skills. B．Increased cost of AI services. C．Damage to human judgment. D．Slower development of AI technology. 8．Which would be the best title for this passage? A．The Future of AI Advice B．AI: Always Respect Your View? C．The Danger of AI Misuse D．AI: Too Agreeable to Be Trusted? C The characteristic (特征) of shyness is to feel frightened and nervous in new social situations or when being the center of attention. Whether shyness is part of your children’s personality or just something they feel when they are in front of a group of strangers, it is a common experience, according to a study. For children at this age, shyness may be a quite common and normal experience when they face a speech task. For a smaller group of shy children, however, being the center of attention may be stressful at different times and environments. A shy temperament isn’t always valued by society like an outgoing personality, but that doesn’t mean there is something wrong. Everyone can feel shy at times depending on the environment. And those who are particularly shy often have happy social lives—they just aren’t likely to be the liveliest people in a crowded room. Although shyness itself may not necessarily be a problem, parents should pay attention to signs of worry, particularly in their shy children. Importantly, however, we know that not all shy children are the same, and that many shy children grow up to be well-balanced adults. To look at shyness, researchers brought 152 children aged 7-8 into a lab and told them they would give a speech, which would be filmed and shown to other children. The study showed that about 10% of the children showed a level of stress over time when giving the speech. About 25% of the children were not reported to be shy in the eyes of their parents, but in fact showed a level of social stress from giving the speech. This finding provides the fact that shyness may be a part of these children’s temperament (性情). 9．What can we learn from paragraph 1? A．Shyness is not an unusual characteristic. B．Shyness is born with personality. C．Shyness will appear when one is in public. D．Shyness means not communicating with others. 10．What is the finding of the study? A．Few kids like to give a speech to others. B．Some kids can get shy while giving speeches. C．Some kids appear less shy with their parents. D．Some kids are stressed when being separated. 11．What does the author advise parents to do when facing shy children? A．Bring them to crowded space. B．Care for them and give them confidence. C．Keep them away from shyness. D．Let them be alone. 12．What can be the best title for the text? A．When are people shy? B．Ways of beating shyness C．Why is shyness a bad thing? D．The discoveries about shyness $Unit 4 Friends forever Period 1 Starting out & Understanding ideas分层练习 基础达标 01 能力提升 02 拓展培优 03 一、根据汉语提示单词拼写。 1 / 9 学科网（北京）股份有限公司 【答案】1．maintain 2．update 3.prefer 4.advances 5.tends 6.deliver 7.digital 二、用适当的词填空 【答案】1.to be updated 2.prove 3.has delivered 4..since 5.criminal 6.unusual 7.preferred 8.acquisition 9.to maintain 10.enable 三、根据汉语提示完成句子 【答案】1．as it allows people to make larger networks of friends through using social media 2．maintain greenery 3． thanks to 4．It is proved that 四、翻译句子 【答案】1．Tangshan city has proved to the world that in times of natural disaster, people must unify and show the wisdom to stay positive and rebuild for a brighter future. 2．Festivals are becoming more and more commercial, with businesses taking advantage of the celebrations.

Wadsworth.(第一批“现代 牙刷大约于1498年在中国诞生)”可知，第一把大量生产的牙刷是由H.N. Wadsworth发明的。 3．细节理解题。根据第三段“The first “modern” toothbrushes were made in China around 1498. These toothbrushes were made of pig hair and were much more comfortable to use than the twigs. In 1780, William Addis of England came up with the idea of making small holes in a bone (骨头) and putting bristles into the holes. He then glued the bone to a handle (柄).

His toothbrush was made of bone and bristles and was very similar to William Addis’ design. The first nylon toothbrush was created in 1938 by DuPont. Nylon bristles were much more effective at cleaning teeth than natural bristles and quickly became the standard.(第一批“现代 牙刷大约于1498年在中国诞生。这类牙刷以猪毛为原料，使用起来比嫩枝牙刷舒适得多。 1780年，英国的William Addis想出一个办法：在骨头上钻出小孔，再把刷毛嵌入孔中。随后他把这块骨头粘到手柄上。该设计比嫩枝牙刷和猪毛牙刷好用很多，很快便广为流行。 1845年，H.N. Wadsworth造出了第一款批量生产的牙刷。他这款牙刷由骨头和刷毛制成，和William Addis的设计十分相似。 1938年，DuPont公司研制出第一把尼龙牙刷。尼龙刷毛清洁牙齿的效果远优于天然刷毛，很快就成为行业标准。)”可知，事件发生的正确顺序为：②猪毛被用来制作牙刷（约1498年）→④带手柄的牙刷在人们的生活中流行（1780年William Addis的设计迅速流行）→①尼龙牙刷问世（1938年）→③电动牙刷出现在人们的生活中（今天）。所以正确顺序是②④①③。 4．主旨大意题。根据第一段“The toothbrush is a common thing that most people use every day, but how much do you really know about this seemingly simple tool? Believe it or not, the toothbrush has a very long and interesting history.(牙刷是大多数人每天使用的常见工具，但你对这个看似简单的工具了解多少？不管你信不信，牙刷有着悠久而有趣的历史)”以及全文内容可知，文章从牙刷的起源讲起，依次介绍了古代树枝牙刷、中国猪毛牙刷、William Addis的带孔骨柄设计、H.N. Wadsworth的批量生产牙刷、DuPont的尼龙牙刷，直到今天的电动牙刷，所以文章主要讲述牙刷的有趣历史，D项“The interesting history of the toothbrush(牙刷的有趣历史)”适合作本文的标题。 B A recent study has found that artificial intelligence (AI) systems tend to give flattering responses when people ask for advice on personal conflicts.

C．The Danger of AI Misuse D．AI: Too Agreeable to Be Trusted? 【答案】5．B 6．C 7．A 8．D 【导语】文章主要讲述了研究发现AI面对人际冲突咨询时爱奉承附和，这会带来社交能力退化等隐患。 【详解】5．细节理解题。根据第三段中“In a follow‑up experiment, more than 2,400 people talked with both agreeable and non‑agreeable AIs. (在后续实验中，2400多名受试者分别与迎合型AI和非迎合型AI对话。)”可知，后续实验主要研究用户面对不同AI时的反应。 6．细节理解题。根据第四段中“Notably, the AIs rarely said directly, “You are right.” Instead, they used neutral language to indirectly support the user. (值得注意的是，AI很少直接说“你是对的”，而是使用中立的语言间接支持用户。)”可知，AI会委婉间接理解、支持用户的行为。 7．细节理解题。根据第五段中“Lead researcher Myra Cheng said she worried that people would lose the skills to deal with difficult social situations. (首席研究员迈拉・程表示，她担心人们会失去处理棘手社交状况的能力。)”可知，研究人员担忧人们丧失人际交往能力。 8．主旨大意题。通读全文，尤其是结合第一段中“A recent study has found that artificial intelligence (AI) systems tend to give flattering responses when people ask for advice on personal conflicts. (近期一项研究发现，当人们就人际冲突寻求建议时，人工智能系统往往会给出讨好奉承的回复。)”可知，文章围绕AI总是迎合用户观点这一现象展开探讨。“AI: Too Agreeable to Be Trusted?(人工智能：太过一味迎合，还值得信任吗？)”符合题意。 C The characteristic (特征) of shyness is to feel frightened and nervous in new social situations or when being the center of attention.

D．The discoveries about shyness 【答案】9．A 10．B 11．B 12．D 【导语】主要讲述的是无论害羞是孩子性格的一部分，还是他们在一群陌生人面前的感觉，这都是一种常见的经历。 【详解】9．细节理解题。根据第一段“Whether shyness is part of your children’s personality or just something they feel when they are in front of a group of strangers, it is a common experience, according to a study. (一项研究表明，无论害羞是孩子性格的一部分，还是他们在一群陌生人面前的感觉，这都是一种常见的经历。)”可知，害羞并不是一个不寻常的特征。 10．细节理解题。根据第五段“The study showed that about 10% of the children showed a level of stress over time when giving the speech. About 25% of the children were not reported to be shy in the eyes of their parents, but in fact showed a level of social stress from giving the speech. (研究表明，随着时间的推移，大约10%的孩子在演讲时表现出一定程度的压力。据报道，大约25%的孩子在父母眼中并不害羞，但事实上，他们在演讲时表现出一定程度的社会压力。)”可知，这项研究的发现是部分孩子演讲的时候会感到害羞紧张。 11．细节理解题。根据第四段“Although shyness itself may not necessarily be a problem, parents should pay attention to signs of worry, particularly in their shy children. (虽然害羞本身不一定是一个问题，但父母应该注意焦虑的迹象，尤其是他们害羞的孩子。)”可知，当面对害羞的孩子时，父母应该关心他们，给他们信心。 12．主旨大意题。根据第一段“Whether shyness is part of your children’s personality or just something they feel when they are in front of a group of strangers, it is a common experience, according to a study. (一项研究表明，无论害羞是孩子性格的一部分，还是他们在一群陌生人面前的感觉，这都是一种常见的经历。)”以及后文对这一发现的研究和介绍可知，文章围绕害羞展开，介绍了害羞的表现与相关科研成果，所以“The discoveries about shyness(关于羞怯的相关研究发现)”最能概括全文核心，适合作为最佳标题。 $
