2021年12月英语六级阅读真题及答案 第3套 仔细阅读2篇
Passage One
Questions 46 to 50 are bad on the following passage.
Dr. Donald Sadoway at MIT started his own battery company with the hope of changing the world's energy future. It's a dramatic endorment for a technology most people think about only when their smartphone goes dark. But Sadoway isn't alone in trumpeting energy storage as a missing link to a cleaner, more efficient, and more equitable energy future.
Scientists and engineers have long believed in the promi of batteries to change the world. Advanced batteries are moving out of specialized markets and creeping into the mainstream, signaling a tipping point for forward-looking technologies such as electric cars and rooftop solar propels.
特拉法尔加海战 The ubiquitous (无所不在的) battery has already come a long way, of cour. For better or wor, batteries make possible our mobile-first lifestyles, our screen culture, our increasingl
y globalized world. Still, as impressive as all this is, it may be trivial compared with what comes next. Having already enabled a communications revolution, the battery is now poid to transform just about everything el.
The wireless age is expanding to include not just our phones, tablets, and laptops, but also our cars, homes, and even whole communities. In emerging economies, rural communities are bypassing the wires and wooden poles that spread power. Instead, some in Africa and Asia are eing their first lightbulbs illuminated by the power of sunlight stored in batteries.
Today, energy storage is a $33 billion global industry that generates nearly 100 gigawatt-hours of electricity per year. By the end of the decade, it's expected to be worth over $50 billion and generate 160 gigawatt-hours, enough to attract the attention of major companies that might not otherwi be interested in a decidedly pedestrian technology. Even utility companies, which have long Viewed batteries and alternative forms of energy as a threat, are learning to embrace the technologies as enabling rather than disrupting.
Today's battery breakthroughs come as the. world looks to expand modern energy access to the billion or so people without it, while also cutting back on fuels that warm the planet. Tho simultaneous challenges appear less overwhelming with increasingly better answers to a centuries-old question: how to make power portable.

To be sure, the battery still has a long way to go before the nightly recharge completely replaces the weekly trip to the gas station. A battery-powered world comes with its own risks, too. What happens to the centralized electric grid, which took decades and billions of dollars to build, as more and more people become "prosumers," who produce and consume their own energy onsite?
领导点评 No one knows which--if any--battery technology will ultimately dominate, but one thing remains clear. The future of energy is in how we store it.

Passage Two
Questions 51 to 55 are bad on the following passage.
More than 100 years ago, American sociologist W. E. B. Du Bois was concerned that race was being ud as a biological explanation for what he understood to be social and cultural differences between different populations of people. He spoke out against the idea of "white" and "black" as distinct groups, claiming that the distinctions ignored the scope of human diversity.
