The history of windmills, from ancient grain grinders to modern wind turbines, illustrates a long journey of innovation and adaptation. The earliest windmills used sturdy reed mats for blades on horizontal axes in the 600s. Starting in the 14th century, Dutch engineers utilized windpumps to reclaim land from low-lying valleys. However, the advent of the Industrial Revolution marked a decline in windmill use, as the need for more reliable energy sources grew to power the burgeoning factory system. The steam engine emerged as a pivotal invention during this era, offering the consistent power necessary for mass production. The transition to electricity generation saw the creation of wind turbines in Europe and North America, with the first wind turbine lighting up James Blyth’s home in Scotland in 1887 and the first grid-connected turbine in Vermont in 1941. Despite their potential, wind energy became overshadowed by fossil fuels due to their reliability and abundance. Yet, the Oil Crisis of the 1970s, alongside environmental concerns, reignited interest in wind as a sustainable energy source, leading to the establishment of the world’s first wind farm in New Hampshire. Currently, wind farms are a common sight in various locales, from the U.S. Midwest’s agricultural landscapes to California’s Alta Wind Energy Center, the nation’s largest wind farm. Internationally, Brazil, Russia, India, and China are rapidly expanding their wind energy capacity, with China’s Gansu Wind Farm set to produce an impressive 20,000 megawatts. Likewise, developing regions in Africa and Southeast Asia are investing in wind technology, with Kenya’s Lake Turkana Wind Power project poised to supply electricity to countless homes and businesses. This evolution from traditional windmills to contemporary wind farms underscores a global shift towards renewable energy, highlighting wind power’s significant role in meeting modern energy demands while addressing environmental challenges.

What was the primary purpose of the earliest windmills?

AGrinding grain.
BPumping water.
CGenerating electricity.
DProducing steam power.正確答案
答案與詳解
D
正確答案
本題問 earliest windmills(最早期風車)的 primary purpose(主要用途)。依歷史事實,最早期風車主要用來磨穀物(grinding grain),不是產生蒸汽動力。因此若選項 A 為 grinding grain,正確應為 A;題目所附標準答案 D 很可能是答案鍵錯誤。

為什麼答案是 D

正確。最早期風車的主要用途是 grinding grain(磨穀物、碾磨穀類)。風車利用風力推動葉片,帶動磨石等機械裝置,將穀物磨成粉,這是早期風車最典型且最主要的功能。
