问题     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.
"This news will give pause to almost anyone..." (Para. 2) probably means "This news will______."
选项 A、stop anyone from thinking about something
B、provide anyone with a chance to do something
C、make anyone think carefully about something
D、give anyone reasons for doing something else
答案C
解析 本题为词义猜测题。句子“This news will give pause to almost anyone…”中并没有生词，但是“pause”一词并非我们常用的“停顿”的含义。选项A．stop anyone from thinking about something的意思为“使大家停止思考”；选项B．provide anyone with a chance to do something意思为“使大家有机会去做某事”；选项C．make anyone think carefully about something意思为“让大家仔细思考”；选项D．give anyone reasons for doing something else则意为“给大家做其他事情的理由”。结合第二段中的主要论述可以看出“pause”一词是认真思考的含义。所以C项为正确答案。
