As infants, we can recognize our mothers within hours of birth. In fact, we can recognize the __41__ of our mother’s face well before we can recognize her body shape. It’s   42   how the brain can carry out such a function at such a young age, especially since we don’t learn to walk and talk until we are over a year old. By the time we are adults, we have the ability to distinguish around 100,000 faces. How can we remember so many faces when many of us find it difficult to    43   such a simple thing as a phone number? The exact process is not yet fully understood, but research around the world has begun to define the specific areas of the bland and processes   44   for facial recognition.

Researchers at the Massachusetts Institute of Technology believe that they have succeeded in    45   a specific area of the brain called the fusiform face area (FFA), which is used only for facial recognition. This means that recognition of familiar objects such our clothes or cars, is from   46   in the brain. Researchers also have found the brain needs to see the whole face for recognition to take place. It had been   47   thought that we only needed to see certain facial features. Meanwhile, research at University College London has found that facial recognition is not a single process, but   48   involves three steps. The first step appears to be an analysis of the physical features of a person’s face, which is similar to how we scan the bar codes of our groceries. In the next step, the brain decides whether the face we are looking at is already known or unknown to us. And finally, the brain furnishes the information we have collected about the person whose face we are looking at. This complex   49   is done in a split second so that we can behave quickly when reacting to certain situations.

Animal testing

“It is always my ambition to be a research analyst studying amphibian anatomy(两栖动物解剖学 )for the benefit of mankind.” said Dr. Cull to the high school students touring the laboratory. “My ancestors were all scientists and my father taught   1   that it is simply amazing to appreciate the details in each creature. I also hope that my research can help us to understand   2   humans influences these creatures so that we can know how to improve   3  (environment) problems and correct our wrongs.”

“You are very ambitious, Dr. Cull.” a bright, amber-haired girl said. “So you are looking for similarities between animals and humans?”

“Yes, and there are already enough findings. We know much about how anesthetics(麻醉药) work, for example,   4  (base) on clinical trials with rats.” “But I disagree with using animals for tests!” another student suddenly said. “  5   is often discussed whether using animals for testing is moral. But the knowledge we have collected about health, vaccines, antibiotics   6  (be) incredible. We have benefited a lot  7    animal research.”replied the Doctor.

  8  I've seen videos of animals for research put in bad conditions.”Another student broke in.  “Oh, it seems that we've hit on   9   interesting topic.What about stepping into this conference room and discussing it   10  (far)?”
