问题     Although I know that many of you think the opposite, most human beings have a high level of intelligence, a good memory and can solve problems easily. They live longer and therefore tend to be much more aware of past and future than we are. They communicate by a set of sounds which carry meaning from the order in which they are placed, and which vary from territory to territory, so that some humans find difficulty in communicating with others according to where they come from--if they have been raised in different country and have not had special training. Humans have also invented a set of marks on paper which they use to represent these sounds and which you may often see them concentrating on. In these two ways they have developed their eyes and ears to a higher level of interpretation than ourselves, but in doing so they have lost the ability to gather much of the information which we continually do both from these and our other senses.
    Most dogs are able to interpret at least part of the vocabulary (voice meanings) of humans, and some of us have learned to recognize some of the pattern of marks which they use to record them on paper so that humans at a different time and in a different place can understand their messages, but it would put our other abilities into danger if we ourselves developed these skills very far. Fortunately, most humans are able to understand a similar amount of our communicatory sounds and behaviour.
    Try going up to a human, sitting down in front of him and raising a front paw in a gesture. He will almost certainly take it and give it a shake, because it is a greeting gesture for humans, too. He will think you are behaving like a human--and nothing seems to please humans more.
    Careful, there is a danger here! You are not a human. You are a dog--and if you are going to be happy you should never forget it. You need to live as a dog. It is all very well changing yourself slightly-to fit in with a human pack, but if you deny your true nature you are going to end up a mad dog and, humans will think, a bad dog. There is always a reason for any animal choosing to live with an animal of a different sort, but all too often we have no choice. We have to live with humans. But humans have consciously decided that they want us with them, although not necessarily for the reason that they believe. They may want you as a watchdog to keep burglars away. They may have some idea that looking after you will teach their pups a sense of responsibility. Or they may simply be in desperate need of companionship, of something to love.
According to the second paragraph, some of the dogs can be trained to ______ .
选项 A、understand at least part of human speech
B、produce sounds meaningful to humans
C、write words on paper for humans to read
D、identify some of the words in writing
