Researchers at the University of Portsmouth found that people can judge whether someone is happy or sad just by watching them walk. The study involved recording participants walking on a treadmill while they recalled either happy or sad memories. Observers were then asked to identify the emotion based solely on the walking pattern. The results were surprising. Observers were able to correctly identify the emotion with a high degree of accuracy. Happy walkers tended to have a more energetic stride, with greater arm swing and a more upright posture. In contrast, sad walkers displayed a slower pace, reduced arm movement, and a more slumped posture. Lead researcher Dr. Sophie Hall explained, “Our study shows that emotions are not just expressed through facial expressions or tone of voice. Body language, including gait, is a powerful communicator of emotional state.” The findings have potential applications in fields such as psychology, where understanding non-verbal cues is important, and even in artificial intelligence, where machines could be trained to recognize human emotions from movement patterns. However, the researchers caution that this is a preliminary study. Cultural differences and individual variations in walking style could affect the accuracy of emotion detection. Further research is needed to explore these factors. 44. What is the main finding of the study? A. Happy people walk faster than sad people. B. Walking style can indicate a person's emotions. C. Treadmill walking is the best way to study emotions. D. Facial expressions are the most accurate way to judge emotions. 45. According to the passage, how do happy walkers typically move? A. With a slow and heavy step. B. With a slumped and relaxed posture. C. With energetic strides and arm swings. D. With minimal arm movement and a hunched back. 46. What potential application of the study is mentioned? A. Developing new types of treadmills. B. Training AI to recognize emotions from walking. C. Creating new exercises for emotional well-being. D. Designing shoes that improve walking posture. 47. What do the researchers suggest about the study's limitations? A. The sample size was too small. B. The study only focused on two emotions. C. Cultural factors might influence the results. D. The observers were not trained professionals.

阅读下面短文，从每题所给的A、B、C、D四个选项中选出最佳选项。 The concept of a 'smart city' is gaining traction worldwide. A smart city uses technology and data to improve the quality of life for its residents, enhance sustainability, and streamline urban services. From intelligent traffic systems to energy-efficient buildings, the applications are vast. One key aspect is transportation. Smart traffic lights can adjust their timing based on real-time traffic flow, reducing congestion and emissions. Public transport can be optimized using data analytics to predict demand and adjust routes accordingly. Some cities are even experimenting with autonomous vehicles and drone deliveries. Another area is energy management. Smart grids can balance electricity supply and demand more efficiently, integrating renewable energy sources like solar and wind. Buildings equipped with smart sensors can automatically adjust lighting, heating, and cooling to minimize energy waste. However, the rise of smart cities also raises concerns. Privacy is a major issue, as the collection of vast amounts of data could lead to surveillance. There is also a risk of creating a 'digital divide,' where only tech-savvy citizens benefit from these advancements, leaving others behind. Furthermore, the high cost of implementing such technologies could strain municipal budgets. Despite these challenges, proponents argue that the benefits outweigh the risks. They believe that smart cities are essential for managing the growing urban population and combating climate change. The key is to implement these technologies responsibly, with strong regulations to protect citizens' rights and ensure equitable access. 48. What is the primary goal of a smart city? A. To replace all human workers with robots. B. To use technology to improve urban life and services. C. To increase surveillance on all citizens. D. To make cities completely self-sufficient in energy. 49. How can smart technology improve transportation? A. By building more roads and highways. B. By eliminating the need for public transport. C. By optimizing traffic flow and public transport routes. D. By encouraging everyone to use private cars. 50. What is a potential downside of smart cities mentioned in the passage? A. They always lead to higher taxes for residents. B. They can only be built in wealthy countries. C. They may compromise privacy and create inequality. D. They completely eliminate the need for city planners. 51. What is the author's overall attitude towards smart cities? A. Completely negative and opposed. B. Cautiously optimistic, acknowledging both benefits and risks. C. Indifferent and uninterested. D. Overly enthusiastic, ignoring all potential problems.

阅读下面短文，从每题所给的A、B、C、D四个选项中选出最佳选项。 The gig economy, characterized by short-term contracts and freelance work as opposed to permanent jobs, has grown significantly in recent years. Platforms like Uber, Airbnb, and Fiverr have made it easier for people to offer their services on a flexible basis. While this offers benefits like autonomy and variety, it also presents challenges. For workers, the gig economy provides flexibility. They can choose when, where, and how much they work.
