任务二 完形填空
Dogs are our friends. In our daily life, dogs are helpful in different ways.
As guide dogs, they look after the blind. In some hospitals, some patients(病人) are too 1, so the dogs even open the doors, and turn on or off the lights for them. They are friendly helpers to make patients feel 2. Sometimes they work with the police and help 3 bad men. They also 4 people in danger. But do you know that people train dogs to help protect insects and animals?
Dogs use their 5 to find out the harmful insects in the trees. For example, in May every year, a kind of insects kill ash trees by 6 their branches（树枝）and roots（树根）. These insects lay eggs in the 7. When the eggs grow into insects, they begin to eat part of the trees. But the eggs of the insects are so small that people can 8 see them. With dogs' sniffing（嗅），scientists can find the 9 and do something.
Dogs also help protect animals in their own ways. Every year, some people catch or even 10 animals for things they need, from the shark's fin to the tiger's fur. Then they make 11 like clothes and medicine and sell them illegally（非法地）. Dogs' special smelling helps the police find them out and 12 the selling. If there is no 13 and selling, there will be no killing.
14 waste（排泄物）is another useful way for dogs to protect animals. Scientists can learn a lot about the animals from the waste. Then they can use the 15 they get to help protect them. Dogs certainly become not only man's best friends, but also the earth's best friends.
