学霸导读 如果未来有外星人来到地球，它们可能会以为这是被禽类统治过的地球，你知道这是为什么吗？让我们一起来看看吧！
If aliens visit Earth in a million years, what will they learn about humans? Will they discover classic works of art or study the technology? Probably not. In fact, many scientists believe that we will be remembered by our love of eating chicken.
W 1 we realize it or not, we are living in an age of chickens. At any moment, there are about 27 billion chickens on Earth. That is three times l 2 than the human population. Most of these animals l 3 for only 5 to 6 weeks. In fact, over 65 billion chickens are k 4 for food every year. At this rate （速度）, chicken will soon pass pork as the world’s most popular meat. Unlike those of many other creatures, chicken bones don’t rot （腐烂） as quickly. This is m 5 because they are buried （埋葬） around other organic materials. The materials preserve the bones quite well,like mummies from ancient Egypt. So, if humans die out or leave Earth in the future, they will leave b 6 billions of chicken bones buried under the soil. Aliens may even think these little birds o 7 ruled the planet!
