中考真题2025年四川省资阳市阅读理解B-好笑且引人深思的研究
There are some researches that “make people laugh, then think”. Let’s look at some of them.
The plant can copy
In 2013, scientists found a strange plant, Boquila trifoliolata. It changes its leaves to look like other plants nearby. Scientists put the plant under a table and a plastic plant above the table. As the plant grew tall, only the part over the table looked like the plastic plant. So scientists think it can “see” what happens around it.
Look at your hair
In which direction do your hair spirals (螺旋) go? A team in France discovered that in the northern half of Earth, most people’s hair spirals to the right. But in the southern half, it goes to the left.
This may be because of a force produced by Earth’s rotation (自转). It makes things spiral to the right in the northern half and left in the southern. Watch how water goes down the drain hole (排水孔) in the kitchen and you will see.
Don’t scare cows
In 1940, Fordyce and William from the US placed a cat on the back of a cow, and made noises beside the cow again and again. The results showed that when cows are scared, they produce less milk. So to get more milk, you shouldn’t scare cows.
