A Canadian psychologist, Dr. David Sherry, has studied the remarkable memory of nutcracker, a bird that stores food，mostly pine seeds, in tiny caches, or holes, in the ground. A native of western North America, one nutcracker makes 100 to 200 separate caches every day in the fall and winter. When spring arrives, the bird returns to these caches to eat the seeds. Dr. Sherry says that months after burying the seeds, the birds remember exactly where they stored them. They fly directly to the holes with no need to hunt and peck. These birds have a highly specialized spatial memory - its amazing, says Dr. Sherry. Dr. Sherry says that memory in many animals is associated with an area in the brain called the hippocampus. He found that food-storing birds have a larger hippocampus than birds that dont store food. Hippocampus damage is one sign of Alzheimers disease, a brain degenerative disease marked by a failing memory. 61. What does the passage mainly discuss? A. Some kinds of birds have excellent memory. B. How birds store food in the ground. C. How birds find their stored food. D. Why birds like to bury seeds in the ground. 62. Nutcracker is a kind of bird that _.

A. returns from north 6 B. flies back to find the stored food C. starts to build its new home D. becomes busy in collecting seeds 64. According to Dr. Sherry, if ones hippocampus is hurt, he may_ . A. lose his ability to talk B. become very forgetful C. die very soon D. become easy to get angry 65. The phrase associated with in the last paragraph has the same meaning as_? A. linked to B. covered with C. located at D. stored in Passage 2 Gordon was a 25-year-old science teacher in 1966 when he bought a brand-new car Volvo P1800. Today, Gordon, now retired, still owns the same Volvo. Last March, he put the 2 millionth mile on the car. Gordons vehicle hit the big 2 million at a TV ceremony held in Times Square in New York City. To what does Gordon owe his cars very long life? Volvos are very strong cars, he said. Also, I drive sensibly. And I take very good care of the car. Gordon changes the oil every 3,000 miles; uses only the same brand of oil; changes the spark plugs(火花塞)every 20,000 miles; washes the car regularly; waxes it at least twice a year; and spends a few minutes each week checking under the hood (车篷), among other things.“Being a science teacher, I have a better idea of the ways things work,”he said. Gordon says the vehicle still has many of its original parts. But many parts, such as the starter motor, the brakes(刹车), and the water pump, have been rebuilt or replaced. Gordons 2 million miles on the road have taken him almost everywhere in the United States, as well as to Canada, Mexico, and Europe. Whether I drive 3 million is more up to me than it is the car, he said. The cars parts may be able to take it, but Im not so sure about my own. 66. From the passage we can guess that _.

Family members said they felt as if theyd walked in circles for hours before help arrived. That detail attracted Andreas interest. Without a compass or specific landmarks, do people who get lost end up walking in circles? she wondered. And if they do, why? th These simple questions fueled Andreas 10-grade science project. Hungry for answers, she went to the library to conduct background research. Among many facts, she discovered that several body organs control direction and movement. For example: , Eyes allow people to see their route. , Structures in the middle ear affect a persons sense of balance. , The brain controls whether a persons right side or left side is dominant(主导的), or exerts more control. Studies of runners strides(步态)show that the dominant foot pushes off with a greater force, which pushes the runner slightly right or left, she explains. 8 Armed with this information, Andrea started an experiment to test whether people who dont know where theyre going end up walking in circles. And several months later, that experiment got a prize at the Intel International Science and Engineering Fair(ISEF)! 71. The aim of Andreas research is to find _. A. why people walk in circles B. why runners usually run in circles C. whether lost people walk in circles D. how can lost people find their place 72. From where did Andrea get her idea to do her 10-grade science project? A. From her textbook. B. From a news report. C. From a science report. D. From an experiment. 73. Andrea found from her research that the most important organ controlling direction is _. A. the brain B. the middle ear C. the eyes D. Both eyes and middle ear 74.
