1 . You must have heard of drug-sniffing dogs (缉毒犬). But how about“drug sniffing squirrels”(松鼠)? Recently, Chongqing police have successfully trained six squirrels to detect drugs. They began their work in early February.
The squirrels have a sharp sense of smell. They can smell food hidden under snow. Being so small,they can search for drugs in the places where dogs may not be able to reach, such as in narrow or high places. The squirrels are trained to use their claws (爪子) to scratch at boxes to tell the police when they find the drugs, according to Chongqing police.
“Our self-developed training system can be used to train different kinds of animals,” Yin Jin, a police dog trainer in Chongqing, said. The key is to develop the animals' conditioned reflex (条件).
First, the animals need to be familiar with (熟悉) the smell of the drug. The trainers can put pieces of cloth with the smell of the drug next to the animals’ food. Next, the animals learn to search for the drug in different situations, such as from a large number of bags or among people walking in crowds. If the animals successfully detect the drug, they are rewarded with snacks and other food. After they are trained for some time, the conditioned reflex will be built and the animals will search for drugs naturally.

2 . When there’s a terrible storm, there are lots of sad stories. Many people lost their houses, their cars and their pets. But sometimes these stories have happy endings (结局), too.
A family in New Jersey, the USA, had a cat called Vivien. She could sing. She could even draw with her wet paws (爪子) on the floor. They all love her very much. When hurricane (飓风) Sandy hit America in October, they moved to a safer place that was far from home. Sadly Vivien got lost. The whole family were worried about her. They looked for her everywhere. But they could not find her. They thought she may die.
But six months later, Vivien returned to their house. People thought it was strange (奇怪的) because no one was able to be sure where Vivien was for all that time and how it could come back.
Many animals are good at finding their way when bad weather happens. People usually say that dogs and cats find their way home by using their sense of smell (气味). But that can not explain (解释) how Vivien found her way back, because Hurricane Sandy blew away the smells of home.

Cows do have best friends and feel stressed when they are separated. Scientists have found that cows are very social animals and a cow always makes friends with other cows. When a cow is with its friends, it feels relaxed, compared with when it is alone.
During breeding season, a male penguin (企鹅) will offer a small stone to a female penguin as a gift. If she takes it, they will become partners. When the female penguin lays an egg, she and her partner may carry it on their feet, because some penguins don’t build nests (鸟巢).
Crocodiles (鳄鱼) swallow (吞) stones. Crocodiles always swallow their food instead of eating it like other animals. They swallow stones which break the food into very small pieces in their stomachs. These stones may stay in their stomachs all their lives.
Elephants use plants to treat pain or other illness. Scientists once found a pregnant (怀孕的) elephant in Africa who ate a kind of plant which was not part of her normal food. Four days later, she gave birth to a baby elephant. The same plant was used by the local pregnant women.
