午后，乐乐和妈妈在动物园观察斑马。

One afternoon, Lele and Mom watched zebras at the zoo.

乐乐问：斑马为什么有黑白条纹？

Lele asked, “Why do zebras have black-and-white stripes?”

妈妈说：“科学家还在研究，没有唯一答案。”

Mom said, “Scientists are still studying it. There is no single answer yet.”

目前较强的证据，指向牛虻等叮咬昆虫。

The strongest evidence so far points to biting insects such as horseflies.

黑白条纹会干扰牛虻靠近和降落，从而减少叮咬。

The black-and-white stripes can disrupt horseflies as they approach and land, reducing bites.

条纹也可能帮助识别；散热仍在研究，伪装不是主结论。

Stripes may also help zebras recognize one another. Cooling is still being studied, and camouflage is not the main conclusion.

乐乐说：“条纹像保护衣，却不只一个用处！”

Lele smiled. “Stripes are like a protective outfit—but they may have more than one job!”

他又问：“那蜘蛛网为什么不会粘住蜘蛛？”

Then Lele asked, “Why doesn't a spider get stuck in its own web?”

科学家还在研究；目前较强证据显示，条纹会干扰牛虻靠近和降落，减少叮咬，也可能有其他作用。

Scientists are still studying zebra stripes; strong evidence shows they can make it harder for biting flies to land.
