In ancient Rome, the gesture was used to convey friendship and 1 (loyal). Pairs of clasped hands even appeared on Roman coins, 2 (indicate) the importance of the action. We can see that the handshake served to convey peaceful intentions, but why? One theory 3 (link) to the fact that most of us are right-handed, and thus would have held a weapon in our right hands. By offering 4 empty right hand, strangers could show they were not armed and had no ill will to the other person. Shaking hands has become an essential part of business. Even though handshakes aren’t 5 (literal) used to confirm whether or not the other person is holding weapons anymore, they’ve maintained 6 (they) signal of showing good intentions. That’s a very important signal in business contexts, 7 people often meet with strangers in highly important settings. However, many 8 (country) don’t shake hands at all. In Japan, people bow 9 each other when meeting, while Ethiopian men touch shoulders. Therefore, it is important 10 (respect) different customs when we meet people from different backgrounds. 四、阅读理解 （2025·四川攀枝花·三模）A new study from Nottingham Trent University (NTU) indicates that people who are more facially expressive are generally more likable and socially successful. The research, which analyzed over 1,500 natural conversations, suggests that complex facial muscle movements can strengthen social bonds and improve social interactions. In the initial phase, researchers engaged with 52 participants in video calls designed to get a range of everyday situations, such as humor, embarrassment and conflict. The participants were further challenged to maintain a still face while their partners attempted to stimulate movement, testing their ability to control facial expressions. Following these interactions, the participants recorded short videos, where they aimed to achieve specific social goals, like disagreeing with someone but without being disliked. These clips of videos were then rated by over 170 independent observers, assessing the readability of the emotions and expressions displayed. The researchers applied the Facial Action Coding System (FACS), a method for measuring facial muscle activity, to evaluate each participant’s expressivity (表现能力). Afterwards, the study extended to analyze an existing database of natural video conversations between 1,456 strangers, where the participants rated their conversational partners’ likability. The study revealed that individuals who were more expressive were more likable by both independent observers and their conversation partners. Additionally, these expressive individuals were easier to read and more skillful at using facial behaviors to achieve their social goals. “This is a study to examine facial expression in real-world interactions,” said the study’s lead author, Eithne Kavanagh. “Our evidence shows that facial expressivity is related to positive social outcomes. It suggests that more expressive people are more successful at attracting social partners and building relationships. It also could be important in conflict resolution.” The research highlights the significant role which facial expressions play in successful social interactions. 1．How did the researchers examine the participants’ ability to control facial expressions? A．By asking them to make complex facial muscle movements. B．By asking them to watch humorous videos and keep a still face. C．By having them use facial behaviors to achieve their social goals. D．By having their partners try to make them produce facial movements. 2．What were the participants asked to do after the first stage? A．Rate the videos of other participants. B．Engage in further social interactions. C．Assess the readability of their own emotions. D．Record short videos under specific conditions. 3．What can we learn about the FACS? A．It is a tool to assess facial muscle activity. B．It decides the social success of individuals. C．It improves the likability of facial expressions. D．It is a method for promoting participants’ likability. 4．What can be the best title for the text? A．FACS: A New Method for Social Science B．Facial Expressions: Important for Social Success C．The Development of Facial Muscle Movements D．The Way to Be Likable and Socially Successful 五、七选五 （2025·福建宁德·三模）Understanding Body Language By learning to recognize the small cues people give off through their posture, gestures, and facial expressions, you can better understand their emotions and intentions. 1 Thus, it is a powerful tool for cross-cultural communication and building relationships. Cultural differences in body language Body language can be interpreted differently across cultures. These variations are crucial for building effective relationships in this globalized world. What’s polite in one culture may seem disrespectful in another. 2 When traveling to a new country or working with remote clients, preparation is key. You can ask from a place of respectful curiosity — what type of communication method and frequency do they prefer? 3 If your gestures seem exaggerated (夸张), you might say, “I may have noticed my using hands a lot, but it’s part of my culture and personality. If it distracted you from anything, let me know so I can clarify.” Common mistakes when reading body language 4 It means that we read too much into why the person said or did it. Another mistake is misunderstanding nonverbal cues. For instance, direct eye contact is seen as a sign of respect in some cultures, while in others, it may be considered rude. To avoid body language misinterpretation, pay attention to the context and overall behavior. 5 Not every gesture has the same meaning in every situation. Ultimately, the best way to handle body language complexities is to stay curious. Always observing others’ nonverbal communication and reflecting on your own consciously is a wise approach. A．So how can you handle these differences? B．What is the significance of body language? C．Most people know how to handle the cultural differences. D．Be mindful of the context in which body language occurs. E．Sincerity is also essential to bridge gaps and understand each other. F．Many of us overanalyze the meaning of body language when interpreting it. G．Understanding body language makes conversations more caring and effective. 六、完形填空 （2024·上海宝山·一模）At times we all wish that we knew what other people were thinking. 1 , people’s facial expressions, movements and posture (姿势) can communicate a lot about what is going on in their minds. Understanding these messages hidden in people’s language can require a lot of skill, but Joe Navarro’s book What EVERY BODY is Saying can help 2 that ability. Small changes in body language can help you recognize if someone is 3 . Even when people don’t lie directly, they sometimes try to hide their feelings. Whether you are 4 with people in business or in your personal life, recognizing these feelings can help you look out for their interests and your own. According to Navarro, establishing a baseline for how a person behaves is important to avoid 5 their body language. Most facial expressions and gestures can mean several different things, so 6 when people use certain expressions. Recognizing this baseline can help you understand whether expressions and gestures indicate a(n) 7 to something you said or not. For example, rubbing one’s eyes may be a sign of 8 with a topic. But if the person has been rubbing their eyes 9 , they might just be tired. When people think of body language, facial expressions tend to come to mind, and these can tell you a lot. For example, if someone keeps looking away from you, they might be distracted or uncomfortable, and pressing one’s lips together often indicates 10 . And if someone keeps looking away or covering their mouth, it might mean they are 11 something. Some people have become good at controlling their facial expressions to conceal their 12 . When dealing with someone like that, look at the rest of their body, especially their feet and legs. Many people bounce their feet when they are happy or excited. 13 , if someone feels uncomfortable, they may point their feet away from the person they are speaking to. Proximity (接近，亲近) to other people is also part of body language. People stand closer to people they like or feel comfortable with than to strangers or people they don’t like. And posture also 14 . Sitting or standing up straight can show that someone feels confident, while sitting with crossed arms indicates that they feel 15 or uncomfortable. Body language can communicate a lot about people's thoughts and feelings, and thus, help you relate to them. 1．A．Frequently B．Generally C．Fortunately D．Frankly 2．A．provide B．develop C．discover D．arouse 3．A．lying B．thinking C．changing D．wishing 4．A．cooperating B．negotiating C．investigating D．interacting 5．A．misguiding B．misinterpreting C．mistrusting D．mismanaging 6．A．look out B．give out C．figure out D．put out 7．A．reaction B．result C．instinct D．insight 8．A．satisfaction B．anxiety C．appreciation D．discomfort 9．A．occasionally B．constantly C．suddenly D．gradually 10．A．agreement B．excitement C．depression D．displeasure 11．A．hiding B．criticizing C．transferring D．explaining 12．A．habits B．expressions C．emotions D．advantages 13．A．In principle B．In contrast C．In all D．In reality 14．A．adjusts B．follows C．moves D．matters 15．A．defensive B．ambitious C．dependent D．aggressive 1 / 5 学科网（北京）股份有限公司 $$ Unit 4 Period 3 Using Language分层练习 基础达标 01 能力提升 02 拓展培优 03 一．汉译英 1． vi. 道歉；谢罪→ n.  道歉；谢罪；辩护 2． vt.忽视；对……不予理会→ n.无知，愚昧→ adj.无知的，(对某事物)不了解的 3． vt.& vi.评价；评判；判断　n.法官；审判员；裁判员→ n.意见；判断力；审判；评价 4． n.

Her willingness to question authority and make her own way helped her earn the 2018 Nobel Prize in Chemistry for her pioneering work in ‌“directed evolution of enzymes (酶)”. Getting there, though, required Arnold to enhance her innovative effort in a process that took decades. Arnold, 64, grew up in a conservative family in a suburb of Pittsburgh, Pennsylvania. At the age of 15, she left home to seek an independent life. She found her own apartment in the city and worked a number of jobs to get by — while still attending high school. The experience taught her valuable life lessons. ‌“I’m not a follower,” she says, ‌“I had to do my thing in my own way and often it was the hard way.” Arnold eventually gave in to her family. She applied to the Mechanical Engineering Department at Princeton University, her dad’s alma mater (母校). After graduating in 1979, she briefly took up jobs in solar technology before realizing it was not where her passion lay. Her determination to make a difference, however, remained unchanged. She went back to school to earn advanced degrees in chemical engineering at the University of California at Berkeley. When she completed her postdoctoral work there in 1986, Arnold joined the faculty at Caltech and has since been working there in the fields of chemical engineering, bioengineering and biochemistry. In terms of research potential, her timing was perfect. The world of DNA was just opening up. Gene splicing (基因剪接) technology was new. ‌“We were hoping to make the code of life work for us,” Arnold recalls. At the time it was a complicated, laborious process that required knowing which changes in the DNA would lead to whatever traits the researchers wanted to change. To make a useful medicine, for instance, the responsible gene had to be modified. Never one to follow the crowd, she thought she had a better idea — use evolution, because DNA was ‌“composed by evolution over the millennia”. Her vision was to speed it up and make it work for us. ‌“Humans have been creating new forms of life by artificial selection for thousands of years,” she says. ‌“From corn to hairless cats, we’ve been modifying DNA to serve us by choosing who goes on to parent the next generation.” She decided to breed proteins that had the traits she was interested in. And as it turned out, proteins were able to adapt quickly to new demands that were being placed upon them. ‌“To me, (directed evolution) seemed obvious,” she recalls. This was not true for everyone. ‌“I got a lot of pushback. People were telling me the only proper way was to sit down and design genes.” Despite the pressure, Arnold persevered. In part, it was her determination and courage. But she doesn’t claim credit for herself. ‌“Anything I do is small. But I enlarge that by sharing ideas with other people,” she says, ‌“They gave me the Nobel Prize really because my ideas were magnified by so many other people.” 1．Which of the following is true about Arnold? A．She never listened to what her parents said. B．She didn’t know early on that her interest was in studying DNA． C．She had to take several part-time jobs to put her through college. D．She applied to study engineering because it’s the best major in his father’s alma mater. 2．Which of the following is not the function of DNA before Arnold’s research? A．To make effective medicine. B．To cultivate plants. C．To change physical features of animals. D．To breed proteins. 3．What is the secret of Arnold’s success? A．Her optimistic attitude towards life. B．Her natural curiosity about everything. C．Her willingness and courage to take an unusual path. D．Her passion for making a difference in the scientific world. 4．What is the best title for the passage? A．The magic of the modification of DNA B．The unusual path to the Nobel Prize C．Being straightforward and stubborn works D．The power of team work in the scientific world 五、七选五 （24-25高二上·北京延庆·阶段练习）Huang Danian, the renowned Chinese geophysicist, was born in 1958 in Guangxi, China. As a keen and able student, Huang went to the UK in 1993 to further his studies. By the time Huang moved back to China in 2008, he had been living and working in the UK for 15 years. 1 . He was driven by the idea that he needed to contribute to his country. As one of the world’s leading experts in deep earth exploration technology, Huang was approached to participate in the “Thousand Talent” programme. Huang was named lead scientist on China’s deep earth exploration programme, developing advanced cameras that can see through the Earth’s crust so that it can be analysed without having to dig into it. 2 . Some described him as a “lunatic” (a madman), but this passion and drive enabled Huang to propel (推动) China’s deep earth exploration technology into a world-leading position. Huang’s dedication contributed to China’s lunar probe Yutu being landed on the moon in 2013. 3 . Huang’s health also paid the price for his commitment to his work. He began having fainting fits in 2012, but paid them little attention. 4 . In November 2016, Huang collapsed and was taken to hospital, where he was diagnosed with cancer. The disease was so advanced that he had just a couple of months to live. Like the true scientist he was, Huang never gave up, but always tried to push forward. Even from his hospital bed, he continued his work, writing letter of reference for his colleagues and replying to questions from his students. 5 . “Our country is in urgent need of talented people,” he said “If we spend more time and pay more attention to the young, masters and even Nobel prize winners may rise among them.” Huang died in January 2017, aged just 58. More than 800 people attended his funeral to celebrate a life that burned so bright, but was so short. A．He set a state-of-the-art lab, sometimes paying for equipment with his own money. B．He stated that he did not have time to go to see a doctor — his work always came first. C．He took up a position at Jilin University, Changchun. D．He had great faith in the talent of the up-and-coming generation. E．He had a good job and a life there, but he gave it all up to return to home. F．He had a talent for his work and was considered a great teacher. G．He also contributed to the launch of the spacecrafts Shenzhou-11 and Tiangong-2. 六、完形填空 （24-25高二上·新疆喀什·期末）Farming Agriculture has a long history in China.

If the condition of your soil is not good, you should 10 it. Moreover, the best harvest is reached when farmers 11 the crops in their fields. For example, do not plant rice 12 in the same field. But if you plant rice in a field one year and wheat next year, you will 13 good crops. Other scientists said that wheat should be planted with 14 between the plants, but Jia Sixie did experiments and 15 that planting wheat close together is better. 1．A．discovered B．recovered C．reported D．repeated 2．A．industrial B．agricultural C．cultural D．commercial 3．A．search B．research C．experiment D．movement 4．A．adventures B．advantages C．tradition D．experience 5．A．practical B．logical C．similar D．regular 6．A．drop B．increase C．grow D．throw 7．A．dreams B．endings C．hopes D．results 8．A．argue against B．go against C．compete with D．deal with 9．A．application B．situation C．condition D．addition 10．A．measure B．improve C．protect D．repair 11．A．keep B．check C．manage D．change 12．A．one after another B．here and there C．now and then D．year after year 13．A．win B．collect C．harvest D．plant 14．A．holes B．lines C．space D．balance 15．A．showed B．meant C．intended D．decided 1 / 9 学科网（北京）股份有限公司 $$
