Use masking tape and cotton balls or other soft materials to wrap an egg up(把……包起来). 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 it 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 really less likely to break. This is because the shell on an egg’s sides is harder than 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 Joseph E. Bonavia, 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.

1. A 推理判断题。由“... eggs that landed on their sides were really 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。
2. D 推理判断题。由 she began to wonder if she told students the right story 可知,他们做实验是为了验证传统结论是否正确。
3. C 写作意图题。由“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.”可知,作者的写作目的是告诉我们不要盲目相信常识。
4. 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来的教训。
