The Year of the Tiger has gone and we have rabbit, dragon…pig year. What words can we think of for pigs?
Some bad words may be silly, dirty, greedy (贪婪)…But are these true?
When we see pigs, they are usually in dirty water or behind dirty fences. But pigs also want to be clean if they can. Pigs have no sweat glands (汗腺), so they have to get cool in water when they feel hot.
If people are greedy, we say they are "pig out". Yes, pigs love eating a lot. But they are useful to people. People not only eat their meat, but also use other parts of pigs. Pig skin is used for glue and shoes. The hair can be used to make brushes. Sometimes, pigs are even used to make medicine.
"He is as silly as a pig!" This expression is wrong. Pigs are very smart animals. Among all animals, they are the third cleverest一monkeys, dolphins and pigs. Scientists think the training of pigs is easier than the training of dogs and cats. Pigs have a very good sense of smell. They can find things nearby or faraway. They can also help the police tosniff outdrugs (毒品) at an airport or at a train station.
