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.

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？（）

The Everglade is a watery plain covered with saw-grass that's the home to numerous species of plants and wild life. And one and half million acres is too big to see it all today. But this tout will offer you a good sampling. Our tour bus will stop first at Tailor Slue. This is a good place to start because it is home to many of the plants and animals typically associated with the everglade. You'll see many exotic birds and of course a world famous alligators. Don't worry. There's a boardwalk that goes across the marsh, so you can look down at the animals in the water from a safe distance. The boardwalk is high enough to give you a great view of the saw grass prairie. From there we'll head at some other marshy and even jungle—like areas that feature wonderful tropical plant life. For those of you who'd like a close view of the saw grass prairie, you might consider running a canoe sometime during your visit here. However, don't do this unless you have a very good sense of direction and can negotiate your way through tall grass. We hate to have to come looking for you. You have a good fortune of being here in the winter, the best time of the year to visit. During the spring and summer the mosquitoes will just about to eat you alive. Right now, they are not so bothersome, but you'll soon want to use an insect repellent.What is the main purpose of the tour?A．To inform. visitors of the park's history.B．To provide an overview of the park's main attractions.C．To show visitors remote places in the park.D．To teach visitors how best to photograph wildlife.
