How well do you know your dog? The answer is, not nearly as well as your dog knows you. Given the right motivation, humans can certainly be perceptive (有洞察力的) enough. But most dog lovers discover, sooner or later, that dogs are sensitive to the behavioral signs of their owners that humans rarely equal. And that’s nothing. Scientists have recently discovered that dogs can distinguish, with amazing accuracy, between breath samples from people with lung cancer and from people without. The dogs have to be trained to do it, of course. But the fact that they can do it at all is remarkable. There aren’t enough biscuits in the world to teach a human to smell at such an extraordinary level of subtlety (细微之处).
This news will give pause to almost anyone who lives with a dog. Just what a dog "knows" is hard to say, because the human idea of "knowing" is so closely related to the ability to express what you know. Even trained cancer-sniffing dogs express their knowledge — their distinction between samples — only by sitting or not sitting. But this is what always happens. We tend to forget the extraordinary powers of the animals we live with simply because we live with them. We tend to humanize them, which means, if nothing else, that we tend to reduce them — in terms of their sensory powers — to our muddling (糊涂 ) level. We can barely take in the fact that when a dog comes up and sniffs us, it is really giving us a check-up.
Not that this will change the dynamic of our relations with man’s best friend. For a while — remembering the cancer-sniffing dogs — some of us will wonder when we see our pets cock their heads, "What are you looking at?" But time will pass, and humans will be humans, and we will forget that the beast we are walking with may already know things about us that we will discover only too late.
What can we infer from this passage?
选项
A、A dog may find its owner’s disease even before doctors.
B、Walking a dog every day will make it more sensitive.
C、Humans may turn to a dog for a discovery about the earth.
D、Humans should find more of a dog before it is too late.
答案
A
解析
本题为推理题,是问从文章中可以推出什么。选项A.A dog may find its owner’s disease even before doctors.从文中可以得出,而后三个选项的结论都无法从文中得出,因此选项A为正确答案。
