Facts you don’t know about animals

People have already known a lot about animals. However, there are still some things about animals that may surprise you. Here are some facts about animals you probably didn’t know.

Cows

Cows do have best friends and feel stressed (焦慮的) when they are separated (分開(kāi)). Sometimes they even a【1】 humans when they are too nervous and angry. However, scientists also found that cows are very social animals and a cow always makes friends with other cows in the herd (獸群). When a cow is with its friend, its heart rate is reduced compared with when it is a【2】 or with a cow from another herd.

Penguins

During breeding (繁殖) season, a male penguin will offer a pebble (卵石) to a female penguin as a g【3】. If she takes it, they will become partners. When the female penguin lays an egg, she and her husband may c【4】 it on their feet, because some penguins don’t build nests.

Crocodiles

When crocodiles eat something, they always swallow (吞) their prey. They don’t chew it like other animals. To help with digestion (消化), they swallow stones which grind up the food in their stomachs. But these stones can h【5】 be defecated (排泄掉), so they may stay in their stomachs all their lives.

Elephants

Elephants use plants to get rid of p【6】 or other illness. Scientists once found a pregnant (懷孕的) elephant in Kenya who kept eating a kind of plant for a few days, while this kind of plant was not part of her regular d【7】. Four days later, she could give birth to a baby elephant quietly. The same plant was used by the local women to help with labor (分娩).

Do you find these facts amazing? Maybe you can introduce some of them to your friends and see how surprised they are when they know the facts!
