The Rise of 5G Technology
The fifth generation of wireless technology, known as 5G, is designed to greatly increase the speed and responsiveness of wireless networks. Compared to 4G, which might offer download speeds of up to 100 megabits per second (Mbps), 5G promises speeds of up to 10 gigabits per second (Gbps). This means a full high-definition movie could be downloaded in a matter of seconds.
Beyond faster speeds for smartphones, 5G is expected to be the key for the development of the Internet of Things (IoT), connecting a vast array of devices from home appliances to industrial sensors. It will enable advancements in autonomous vehicles, smart cities, and remote surgery due to its low latency, meaning minimal delay in data transmission.
However, the deployment of 5G requires a denser network of base stations and antennas because 5G signals have a shorter range than 4G. This has raised some public concerns about potential health risks and visual pollution, although major health organizations like the WHO have stated that, within international guidelines, no adverse health effects are expected.
5G technology offers significantly faster download speeds than 4G. A. Right B. Wrong C. Not mentioned
5G networks will primarily be used for making phone calls. A. Right B. Wrong C. Not mentioned
The low latency of 5G is crucial for applications like remote surgery. A. Right B. Wrong C. Not mentioned

Renewable Energy: Solar Power
The quest for sustainable energy has made solar power a focal point of research and development. Unlike fossil fuels, solar energy is abundant, renewable, and produces no air pollution during operation.
( ) The most common method of harnessing solar energy is through photovoltaic (PV) cells, often made from silicon. When sunlight hits these cells, it knocks electrons loose, creating an electric current. This direct conversion of light to electricity is what powers everything from small calculators to entire homes.
( ) Another method is Concentrated Solar Power (CSP). This technology uses mirrors or lenses to concentrate a large area of sunlight onto a small receiver. The intense heat generated is then used to produce steam, which drives a turbine connected to an electrical generator. CSP is typically used for large-scale power plants.
( ) Despite its advantages, solar power faces challenges. The initial installation cost can be high. Furthermore, energy production is intermittent – it doesn't work at night and is less efficient on cloudy days. This necessitates the development of efficient energy storage systems, like large batteries.
( ) The future of solar energy looks bright. Technological advancements are continuously reducing the cost of PV cells and improving their efficiency. Innovations such as solar roof tiles and transparent solar panels for windows are integrating solar collection seamlessly into our built environment, promising a cleaner energy future.
任务一：概括大意（第23~26题） A. Challenges of Solar Energy B. How Photovoltaic Cells Work C. The History of Solar Power D. The Future Potential E. How Concentrated Solar Power Works F. Comparing Solar and Wind Energy
任务二：完成句子（第27~30题） 27. Solar energy is considered sustainable because it is... 28. Photovoltaic cells generate electricity by... 29. A major challenge for solar power is its... 30. New innovations include solar panels that can...
A. converting sunlight directly into electricity B. intermittent nature C. abundant and renewable D. used for large-scale power generation E. be integrated into building materials F. very cheap to install
第四部分：阅读理解（第31~45题，每题3分，共45分） 下面有3篇短文，每篇短文后有5道题。请根据短文内容，为每题确定1个最佳选项。
第一篇：The Mystery of Dark Matter
A vast majority of the universe is made up of stuff we cannot see. Astronomers call this "dark matter." It does not emit, absorb, or reflect light, making it completely invisible to telescopes. So, how do we know it's there?
We detect dark matter through its gravitational effects. The visible matter in galaxies, like stars and gas, does not have enough mass to account for the strong gravity that holds galaxies together. Without the extra gravity provided by dark matter, galaxies would fly apart. Similarly, the way galaxies move within clusters also suggests the presence of a large amount of unseen mass.
What dark matter actually is remains one of the biggest puzzles in physics. It is not composed of atoms or the particles we know. Leading candidates are hypothetical particles such as WIMPs (Weakly Interacting Massive Particles). Experiments deep underground are trying to detect these elusive particles by looking for the rare occasions they might bump into ordinary matter.
Understanding dark matter is crucial because it governs the large-scale structure of the universe. Its gravitational pull acted as a scaffold upon which visible matter coalesced to form galaxies and clusters billions of years ago.
Why is dark matter invisible to telescopes? A. It is too far away. B. It doesn't interact with light. C. It is made of ordinary atoms. D. It is hidden behind stars.
How do astronomers infer the existence of dark matter? A. By taking pictures of it with special cameras. B. By analyzing the light it emits. C. By observing its gravitational influence. D. By creating it in laboratories.
The word "elusive" (Paragraph 3) is closest in meaning to: A. dangerous. B. heavy. C. difficult to detect. D. easy to find.
According to the passage, what would happen to galaxies without dark matter? A. They would shine brighter. B. They would collapse. C. They would not have formed. D. They would fly apart.
What role did dark matter play in the history of the universe? A. It provided the light for the first stars. B. It formed the core of planets. C. It created a scaffold for galaxy formation. D. It caused the Big Bang.
第二篇：The Impact of Artificial Intelligence on Engineering
Artificial Intelligence (AI) is rapidly transforming the field of engineering. It refers to the simulation of human intelligence in machines that are programmed to think and learn. In engineering design, AI algorithms can analyze vast datasets to optimize designs for weight, strength, and material usage, often resulting in solutions that humans might not conceive. This process, known as generative design, is revolutionizing industries from aerospace to automotive.
In manufacturing, AI-powered robots and vision systems enhance precision and efficiency on assembly lines. They can perform repetitive tasks with consistent accuracy and work alongside humans, taking over dangerous jobs. Predictive maintenance is another major application. AI systems analyze data from sensors on machinery to predict when a part is likely to fail, allowing for repairs before a breakdown occurs, thus minimizing downtime.
However, the integration of AI also presents challenges. There is a significant need for upskilling the workforce, as engineers must now understand data science and AI principles. Ethical considerations, such as decision-making accountability and job displacement, also need to be addressed. Despite these hurdles, the synergy between AI and engineering is creating smarter, safer, and more efficient systems, pushing the boundaries of what is possible.
What is a key benefit of "generative design" mentioned in the passage? A. It makes engineers obsolete. B. It creates optimized designs that humans might not think of. C. It is only useful for software engineering. D. It makes the design process much slower.
How does AI contribute to predictive maintenance? A. By replacing all old machines with new ones. B. By analyzing sensor data to forecast equipment failure. C. By allowing machines to repair themselves automatically. D. By reducing the number of sensors needed.
According to the passage, what is a challenge associated with AI in engineering? A. AI cannot learn from data. B. AI systems are too expensive to build. C. Engineers need to learn new skills like data science. D. AI makes systems less efficient.
The word "synergy" (Paragraph 3) most likely means: A. competition. B. replacement. C. interaction that produces a better result. D. problem.
What is the main topic of this passage? A. The history of robotics. B. The challenges of manufacturing. C. The influence of AI on the engineering field. D. The ethical problems of automation.
