Use masking tape and cotton balls or other soft materials to wrap(包) an egg up. Then, drop it from the roof of your school.
Have you ever done this before? It's a classic science experiment called the egg drop challenge. Every year, many students around the world do it. The goal is to keep the eggs from breaking. But as many students quickly learn, that's easier said than done. Once the eggs break, teachers explain the physics behind the experiment. One popular conclusion is that eggs sitting straight are less likely to break than eggs sitting horizontally(水平地). But is it true?
Tal Cohen is a professor. After running the egg drop challenge for years, she began to wonder if she told students the right story. To find out, she and her team bought more than 200 eggs and took them into the lab.
In their experiments, the researchers found that eggs that landed on their sides were actually less likely to break. This is because the shell on an egg's sides is harder than that on its ends. When a dropped egg hits the ground on its side, the shell can soak up some of the blow. "It's just like the human body," explained one of the researchers. "Imagine you are falling from a height. If you land with your legs straight, you'll break your bones. You'll want to bend your knees, and that's what the egg is doing."
Cohen's findings remind us that not everything is true. For this reason, we should keep an open mind and never be afraid to "break" some common wisdom.

答案
文章围绕鸡蛋掉落挑战展开，指出传统观点认为直立的鸡蛋更不易碎，而Tal Cohen教授团队通过实验发现，侧面着地的鸡蛋因侧面蛋壳更硬、能吸收冲击力而更不易碎，这一发现提醒人们不应盲从常识，要保持开放心态。
1. B 细节理解题。由句子"In their experiments, the researchers found that eggs that landed on their sides were actually less likely to break. This is because the shell on an egg's sides is harder than that on its ends."可知，鸡蛋侧面着地更不容易碎是因为侧面的蛋壳比两端更坚硬。
2. A 推理判断题。由eggs that landed on their sides were actually less likely to break可知，这与传统结论相反，由此可推断，传统结论是错误的。
3. D 推理判断题。文中提到"After running ... she began to wonder if she told students the right story. To find out, she and her team ... took them into the lab. "，说明他们做实验是为了验证传统结论是否正确。
4. C 推理判断题。由最后一段可知，作者的写作目的是告诉我们不要盲目相信常识。
5. B 主旨大意题。本文主要内容是关于鸡蛋下落挑战的新发现及其带给我们的启示。
