8 阅读理解。 For six hours we shot through the landscape of the Karoo desert in South Africa. Just rocks and sand and baking sun. Knowing our journey was ending, Daniel and I just wanted to remember all we had seen and done. He used a camera. I used words. I had already finished three notebooks and was into the fourth, a beautiful leather notebook I"d bought in a market in Mozambique. Southern Africa was full of stories. And visions. We were almost drunk on sensations. The roaring of the water at Victoria Falls, the impossible silence of the Okavango Delta in Botswana. And then the other things: dogs in the streets, whole families in Soweto living in one room, a kilometre from clean water. As we drove towards the setting sun, a quietness fell over us. The road was empty-we hadn"t seen another car for hours. And as I drove, something caught my eye, something moving next to me. I glanced in the mirror of the car; I glanced sideways to the right, and that was when I saw them. Next to us, by the side of the road, thirty, forty wild horses were racing the car, a cloud of dust rising behind them-brown, muscular horses almost close enough to touch them, to smell their hot breath. I didn"t know how long they had been there next to us. I shouted to Dan: "Look!", but he was in a deep sleep, his camera lying useless by his feet. They raced the car for a few seconds, then disappeared far behind us, a memory of heroic forms in the red landscape. When Daniel woke up an hour later I told him what had happened. "Wild horses?" he said. "Why didn"t you wake me up?" "I tried. But they were gone after a few seconds." "Are you sure you didn"t dream it?" "You were the one who was sleeping!" "Typical, he said. "The best photos are the ones we never take." We checked into a dusty hotel and slept the sleep of the dead. 1. During their journey in Africa, the two travelers________ A. made friends with local residents B. complained about the poor living conditions C. enjoyed the sunset in the Karoo desert most D. recorded their experiences in different ways 2. What does the phrase "heroic forms" in Paragraph 4 refer to? A. Racing cars. B. Wild horses. C. Eye-catching locals. D. Running dogs. 3. What did Daniel think when he woke up and was told what had happened? A. He always missed out on the best thing. B. He had already taken beautiful pictures. C. A sound sleep was more important. D. The next trip would be better. 4. What is "the passage mainly about? A. How to view wildlife in Africa. B. Running into wildlife in Africa. C. Tourist attractions in southern Africa. D. Possible dangers of travelling in the desert.

10 2008年5月26日上午，一架米—26直升机吊装了一台重13.2t的重型挖掘机前往唐家山堰塞湖坝体。到达坝体后，假设直升机悬停在空中（见图），使挖掘机由静止开始从距地面60m的高空。以1/360m/s 2的加速度沿竖直方向向下运动一段时间，接着再匀速运动相等的时间刚好到达地面。若挖掘机触地前瞬间悬绳拉力即刻减为零，挖掘机着地过程中与地面的作用时间为0.02s，g取10m/s 2。求：（1）挖掘机匀速运动时的速度大小。（2）着地过程中，挖掘机对地面的平均作用大小。
