Other people, though, can’ t tell when they’ re holding a map upside down. Are the directionally challenged just bad learners? Not all of your navigational (导航的 )skills are learned. Research shows that your sense of direction is innate. An innate ability is something you are born with. Your brain has special navigational neurons— headdirection cells, place cells, and grid cells (网格细胞 )— and they help program your inside pass when you’ re just a baby. In 2020, scientists carried out an experiment to study baby rats’ neural activity in their brains. Although the rats were newborns, the researchers discovered that their headdirection cells (which help them recognize the direction they’ re facing) were fully grown and developed. The rats, it seemed, were born with a sense of direction. And they hadn’ t even opened their eyes yet! Humans, of course, are not rats. But the hippocampus— the brain area we use for navigation— is similar in most mammals. If the rat’ s pass develops this way, then it’ s likely that a human’ s pass does, too. If we’ re born with a sense of direction, then why are some people so good at getting lost? The scientists found that the two other cells— place and grid cells— developed within the first month. Place cells are thought to help us form a map in our mind, while grid cells help us navigate new and unfamiliar places. The two cells work together, and that’ s where the trouble might be. People who took part in a 2020 study played a video game that required them to travel quickly between different places. Monitoring their brains, the scientists found that grid cells helped the gamers recognize where they were— even without landmarks. According to researcher Michael Kahana, differences in how grid cells work may help explain why some people have a better sense of direction than others. 32. What did the 2020 research find? A. Rats have a natural ability to recognize directions. B. Rats’ hippocampus is different from that of humans. C. Rats usually find their way without opening their eyes. D.

Grid cells help us reach the place we are going to. C. They help us use a pass when we lose our way. D. Place and grid cells grow later than headdirection cells. 34. Why are some people so good at getting lost? A. They can’ t remember landmarks. B. Their grid cells can’ t work very well. C. They are unfamiliar with new places. D. Their ability to follow directions is poor. 35. What is the text mainly about? A. Human navigational skills. B. The pass in rats’ body. C. Why grid cells are useful. D. How homing pigeons work. 第二节 (共 5小题；每小题 2分 , 满分 10分 ) 根据短文内容 , 从短文后的选项中选出能填入空白处的最佳选项。 选项中有两项为多余选项。 With the year ing to an end, a vacation is inescapable. Travelling in winters is never easy.
