Choose those that are connotations of the word “dog”.

Passage 3

Questions 11 to 15 are based on the following passage:

The dog has always been considered man?s best friend. Always noted for being particular faithful in watching over children, he also has his place by the fireside, in the cow pasture, on the sheep range, and beside the hunter or blind. He is easy to train, works hard, and often performs being largely replaced by the plane and helicopter.

Because he howls or whines in the presence of impending death, the dog was once thought to have supernatural powers and believed to be capable of seeing gods and ghosts in visible to people. Actually, the basis for these beliefs lies in the dog?s sensitivity to people?s feelings and his superior hearing ability and sense of smell, which enable him to detect signs hidden from human observation. His record of saving lives is outstanding, for he often gives warning of fire and other dangers not noticed by his master.

The dog&39;s major contribution, however, has been to medical research. Both his diet and his structure are comparable to those of the human being, and so he has been the subject, of countless demonstrations and experiments. Open-heart surgery has been made possible largely because of the dog. But his sacrifice has repaid his own species as well by safeguarding it from rabies(狂犬病), distemper, and other diseases.

In some countries, however, people treat their pets like members of their own families, or perhaps better.

Questions 24 to 27 are based on the following passage.

Humans have long turned to the dog for its nose,especially in its ability to hunt, track missing people, and searchfor drugs- But there is a new challenge： Bomb-detecting dogs now have to learn to find the increasingly common Improvised Explosive Devices (IEDs)( 临时组装的爆炸装置） that can be assembledfrom materials not dangerousby themselves.“ So we’ re now asking dogs not just to find a needlein ahaystack (干草堆）一 now the problem is more like saying to the dog we needyou to find any sharpobject in the haystack, ” says Clive Wynne，a professor atArizona State University.

Wynne directs the study that develops methods to train dogs to identify a wide variety of ingredients that could be usedto make bombs. The dogs not only have to detect whether explosive materials are present,they also have to determine if the chemicals they smell could combine to form. an explosive mixture. The dogs needto learn that when combined with other elements, even sugar could be usedin abomb. “ we want the dogs to grasp the concept of ‘ this might explode ’”.

Wynne says the big problem is that IEDs arejust that---improvised and completely unsteady.A dog ’s nose canbe over a thousand times more powerful than a human ’s nose. Some agenciesspent billions of dollars over the last 15 yearstrying to createatechnical replacement for the noseof the dog, and at the end of all that they just had to admit “ No, we cannot get close ”. Wynne thinks his team candevelop bomb sniffing (嗅，闻）dogsthat can detect IEDs at a small part of that price. All it takes is patience.
