You must have heard of drug detection dogs（缉毒犬）. But how about “drug detection squirrels（松鼠）”? Recently, Chongqing police have successfully trained six squirrels to find drugs. They began their work in early February.

Squirrels have a good sense of smell. They can smell food 30 centimeters under snow. Being so small, they can look for drugs in tiny or high places. The squirrels are trained to use their claws（爪子）to scratch at boxes to tell the police, if they find 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, told The City Paper. It’s important to develop the animals’ conditioned reflex（条件反射）.

First, the animals need to know the drug’s smell well. The trainers can put pieces of cloth with the drug’s smell next to the animals’ food. Next, the animals learn to look for the drug in different situations, such as from a large number of bags or among people walking in crowds.

If the animals successfully find the drug, they are given snacks and other treats. After training for some time, the conditioned reflex will be built and the animals will look for drugs naturally.

The dumpling is a traditional Chinese dish. On the Chinese Spring Festival, most families make a lot of delicious dumplings. To make them, follow this easy process.

【小题1】 When the dough (面团) is ready, we can begin to make dumpling wrappers (饺子皮). We turn the dough into small, thin and round pieces. 【小题2】

When the wrappers are done, it’s time to prepare the filling (馅). Usually, we use meat such as beef or pork and some vegetables such as cabbages or carrots for filling. 【小题3】 We must cut these things into small pieces. 【小题4】

When all these preparations are done, we can start making dumplings. Put a spoonful of filling in the center of the wrapper, fold (折) the wrapper in half and close up the opening. Don’t just cover the filling with the wrappers. 【小题5】 The best shape of dumplings is just like a ship, because when they are put in the pot, they look like ships in the sea. The smell can make your mouth water.

Last, cook the dumplings in the pot with hot water.
