单项选择题 听力原文： Geologists say they knew that a large earthquake was coming in South Asia, but they did not know when. The Himalayan Mountains were formed some 150 million years ago after the landmass that is now India broke off from Antarctica, drifted north and collided with the rest of Asia. Scientists say the South Asian land mass is still moving towards North Asia at the rate of about two centimeters a year, making the area prone to earthquakes. Harley Benz is a researcher at the U.S. Geological Survey earthquake information center. 'It's a broad zone of deformation, and across this zone that extends 1,000 kilometers, you have a whole series of faults and folds.' Another earthquake-prone region is along the 1300 kilometer San Andreas Fault in California. It is here that John Rundle, a physics and engineering professor at the University of California at Davis, is testing his earthquake computer simulation.According to the news, the current Indian landmass was once part of ______ millions of years ago.A．AntarcticaB．AfricaC．AustraliaD．America

单项选择题 听力原文： The government of Pakistan says it now thinks that more than 38,000 people were killed by the South Asian earthquake a week ago. The number injured has risen to more than 60,000. In some of the areas worst affected, heavy rain and strong winds again temporarily grounded helicopter flights. BBC correspondent Jonathan Head reports now from Muzaffarabad: The earthquake struck rich and poor alike. This was a doctor's home in surgery. One week on his family are still retrieving what they can. It isn't much. But it's so much harder on the poor. In the hills outside Muzaffarabad a man complains all he's had to eat is biscuits. 14-year-old Javed took me onto the roof of what had been his house, now crushed to a few feet of rubble. 'This earthquake killed my sister', he told me, 'and my mother was badly injured'. His home today, like countless others here, is a grimy camp.The total casualties have surpassed ______.A．38,000B．60,000C．68,000D．98,000

单项选择题 史密斯：根据《国际珍稀动物保护条例》的规定，杂种动物不属于该条例的保护对象。《国际珍稀动物保护条例》的保护对象中包括赤狼。而最新的基因研究技术发现，一直被认为是纯种物种的赤狼实际上是山狗与灰狼的杂交种。由于赤狼明显须要保护，所以条例应当修改，使其也保护杂种动物。张大中：您的观点不能成立。因为如果赤狼确实是山狗与灰狼的杂交种的话，那么，即使现有的赤狼灭绝了，仍然可以通过山狗与灰狼的杂交来重新获得它。以下哪项最为确切地概括了张大中与史密斯争论的焦点？（）
