1 D A team of scientists proved that seals had a very good sense of hearing. These men trained blind seals to expect food when they heard sounds. The seals always began snapping(猛咬) when a strong signal was sounded. It was proved that even a soft signal, a considerable distance away, could make these sea animals respond. That should make the fisherman who makes much noise while working, or talks loudly, start thinking. The same team of scientists also trained seals to recognize different sounds. One bell-tone meant food ,two bell-tones meant no food. In the beginning, the seals made mistakes when the two bell-tones were sounded. They were given a light tap after each mistake. The seals were good learners. They easily learned to tell the difference between the sounds. 67.Why was it necessary to use blind seals? Because they______. A. were unable to use sight for clues B. had better hearing C. were waiting to be fed D. were the only animals to be found 68. To those seals strong signal meant_____. A. snapping B. nothing C. food D. a light tap 69. The article doesn’t say directly but suggests that fishermen usually think______. A. seals have no good sense of hearing B. seals have good sense of hearing C. seals can only recognize bell sounds D. seals can not hear soft or long distant sounds 70. Which title will be the best to suit the article? A. Clever Seals B. Smart Learners C. An Underwater School D. An Unknown School

9 植物的光合作用受CO 2浓度、温度与光照强度的影响。下图为在一定浓度的CO 2和适宜温度条件下，测定某植物叶片在不同光照条件下的光合作用速率。下列有关说法不正确的是 [ ] A．在a点所示条件下，该植物叶肉细胞内能够产生ATP的部位是叶绿体 B．该植物叶片的呼吸速率是5mg/100cm 2mf·h C．在一昼夜中，将该植物叶片置于c点光照下11小时，其余时间置于黑暗中，则每100cm 2叶片一昼夜中CO 2的净吸收量为45mg D．若已知该植物光合作用和呼吸作用的最适温度分别为25℃和30℃。若将温度提高到30℃的条件下(原光照强度和CO 2浓度不变)，则曲线图中b点将右移，c点将下移
