Question

閱讀理解。

     The Year of the Dog has gone and this year we have pigs. What words can we think of for pigs? Some
bad words maybe, like silly, dirty, greedy (貪婪)…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 "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-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 (嗅覺). They can find things nearby or
faraway. They can also help the police to sniff-out drugs (毒品) at an airport or at a train station.
