While most of the other students hurriedly left to enjoy the pleasant weather or to relax at the student union, Julie remained to ask me questions about the next week’s exam. She had clearly already done some serious studying.Julie never made it to the exam. The day after our conversation, she was hit by a large truck as she rode a bike through a crossroads. I was sad to hear that Julie lay unconscious (昏迷的) in a hospital across town from our university.Nurses silently came and went from Julie’s room. Her parents stood nearby quietly. Then the doctor entered the room and said to Julie’s parents and two brothers, “Your Julie has only a few hours to live.” He continued to ask, “Would you think about donating some of Julie’s organs (器官)?”At the same time in a neighboring city, a woman called Mary was trying to see better in her small living room. Her eyes followed every movement of her lively two-year-old baby. This mother was storing up memories when she could no longer see her child. Several cities away, a young father called John was reading to his two sons in the hospital. However, he was told to have only weeks to live.

Careful sniffing( 嗅) tells the cat if something is safe to eat.Cats have a pair of vomeronasal organs(犁鼻器) on the roof of the mouth. When the cat wants tosniff, she will breathe the air in through her mouth. At this moment, she will often squint(斜视) hereyes and maybe even flatten(使…平坦) her ears. This makes her look like she is making faces. Thevomeronasal organs will then analyze(分析)the smell---almost as if the cat is tasting the smell.When you come home from outside the house, your cat can smell what you had for lunch and for amid-afternoon snack. She can smell the people you shook hands with and your neighbour you stopped to talk to and hug. She can smell the grass brought under your s hoes as you took a shortcut across the lawn. Your cat’s sense of smell is so good that she can smell difference between a gallon of water with a teaspoon of salt in it and plain water. In comparison, we think of salt as completely tasteless.Cats have scent glands(臭腺) on each side of the forehead, on the chin, the lips and next to the tail. When your cat rubs up against your hand, your leg, the sofa, and your bed, she is leaving her scent in those things. She will then use her sense of smell to recognize “her” things, people and even other pets in the home.If you want to have fun with your cat’s sense of smell, take some small bits of different things, such as a bit of chicken, some flowers and some fish. Place each different scent under a piece of paper towel(so your cat cannot see any of them) and encourage your cat to investigate and find what kind of food she likes to eat best.41. Cats know whether the food is fit to eat or not with their____________.A. sense of touchB. scent glandsC. organs of smellD. sense of taste42. The third paragraph was written mainly to prove that _____________.A. cats are very smartB. cats have a good sense as dogsC. salty water has a special smellD. cats’ sense of smell is excel lent43. What does your cat do when it rubs against your foot?A. She puts her scent on it.B. She shows respect to you.C. She asks you to play with her.D. She smells where you were just now.44. What does the word “investigate” mean in the last paragraph?A. Smell.B. See.C. Look.D. Send.45. The passage mainly tells us _________________.A. cats are one of our best friendsB. cats have sharp sense of smellC. sense of smell is very importantD. cats know if something is safe to eat第II卷(非选择题,共60分)四、词汇运用(共10题,每题1分,计10分)A) 根据句意及汉语提示,写出各单词的正确形式,每空一词。
