The pond was next to an abandoned (被遗弃的) palace. One day, the frog made up his mind to have a look at the palace. So he jumped up onto an old window and jumped through it .He found himself in a wonderful pond. It was filled with frogs. Everyone lived happily there. They even held various ac tivities to spend their time. Although other frogs didn’t welcome him, he decided to stay.One night, the other frogs caught him and threw him back through the window. They said, “You don’t belong to us. Disappear before us the same today and forever.”The frog woke up in a dark, cold and uncomfortable room. There was a young boy in the room, and the boy was happy to see the frog. Soon they became friends. The boy looked after the frog as well as possible, and he even caught the flies for the frog. Howev er, the frog wasn’t satisfied with his life. He kept thinking about all the good things in the wonderful pond, and wanted to go back there. One night, when it was getting colder, the frog jumped out of the window.He went to the North Pole. It was so cold that the frog quickly jumped back through the window. This time, he found himself in a desert! No matter how many times the frog jumped through the window, he would always come out at either the North Pole or the desert. The sad frog missed the kind boy. He realized he missed the happy life he used to have. But now it was too late.根据短文内容判断正(A) 误（B）( ) 61. One day the frog got to a wonderful pond through a new window.( ) 62. The frog wasn’t given a warm welcome by the frogs in the wonderful pond.( ) 63. In a dark, cold and uncomfortable room, the frog even caught flies for the boy after they became friends.( ) 64. The frog tried his best to jump through the window, but he would come out at neither the North Pole nor the desert.( ) 65. From the story, we know we should enjoy our happy life that we have owned.(D)Are fingerprints(指纹)the most accurate(准确的)way to identify(识别)a person? Well, scientists in the US say that “brainprints” could be better. They developed a technology that ca n identify people based on their brain activity, and it’ s surprisingly accurate.Scientists recorded the brain activity of 50 volunteers. They scanned (扫描) the volunteers’ brains while they looked at 500 different pictures. The pictures that were chosen can cause very different responses to different persons. Scientists asked the volunteers about which foods and famous people that they loved and hated,and they used that information in the study. It showed that the volunteers’ brains all responded differently to each picture.When they saw different pictures,a special computer program was able to create a“brainprint”.These“brainprints” allowed scientists to identify each volunteer with 100 percent accuracy.Brainprints have better advantages than fingerp rints. That’ s because fingerprints can’ t be changed. Once they are stolen,others can use them for anything they want. But brainprints can be changed. That’s because it changes when a person’s brain responds to different things,but the brainprint is still unique(独特的) to them. It is impossible for anyone to steal a brainprint from someone since the person could then “reset” their brainprint. It means the person can change their brainprint and make it ready to be used again.Scientists think the brainprint could one day be used in some areas to protect dangerous information, 根据短文内容选择最佳答案。
