This immense chasm has been formed by an underground stream which has 12.___________________ through a flaw in the rocks. The entrance to the cave is on a plateau in the Dauphine Alps. As it is only six feet across, it is 13._________________. The cave might never have been discovered has not the entrance been spotted by the distinguished French pot-holer, Berger. Since its discovery, it has become a sort of pot-holers' Everest. Though a number of descents have been made, much of it still 14.________________________.
A team of pot-holers recently went down the Gouffre Berger. After entering the narrow gap on the plateau, they climbed down the 15.__________ of the cave until they came to narrow corridor. They had to edge their way along this, sometimes wading across shallow streams, or swimming across deep pools. Suddenly they came to a waterfall which dropped into an underground lake at the bottom of the cave. They 16.____________ the lake, and after loading their gear on an inflatable rubber dinghy, let the current carry them to the other side. To protect themselves from the icy water, they had to wear special rubber suits. At the far end of the lake, they came to huge piles of rubble which had been washed up by the water. In this part of the cave, they could hear an 17.____________ booming sound which they found was caused by a small waterspout shooting down into a pool from the roof of the cave. 18.___________________ a cleft in the rocks, the pot-holers arrived at an enormous cavern, the size of a huge concert hall. After switching on powerful arc lights, they saw great 19.____________ -- some of them over forty feet high -- rising up like tree-trunks to meet the stalactites suspended from the roof. Round about, piles of limestone glistened in all the colours of the rainbow. In the eerie silence of the cavern, the only sound that could be heard was made by water which 20.__________________ from the high dome above them.
Lesson 43 Fully insured
1. ______________ are normally willing to insure anything. Insuring public or private 2. is a standard practice in most countries in the world. If, however, you were holding an open air garden party or a fete it would be equally possible to insure yourself in the event of bad weather. 3. , the bigger the risk an insurance company takes, the higher the you will have to pay. It is not uncommon to hear that a shipping company has 4. the cost of 5. . But the claim made by a local authority to recover the cost of salvaging a sunken pie dish must surely be unique. 6. it was an unusual pie dish, for it was eighteen feet long and six feet wide. It had been purchased by a local authority so that an enormous pie could be baked for an 7. fair. The pie committee decided that the best way to 8. the dish would be by canal, so they insured it for the trip. 9. it was launched, the pie committee went to a local inn to celebrate. At the same time, a number of teenagers climbed on to the dish and held a little party of their own. Dancing proved to be more than the dish could bear, for during the party it 10. and sank in seven feet of water. The pie committee telephoned a local garage owner who arrived in a recovery truck to salvage the pie dish. 11. in their wet clothes, the teenagers looked on while three men 12. into the water to 13. the dish.
They had little 14. it, but hauling it out of the water proved to be a serious problem. The sides of the dish were so smooth that it was almost impossible to attach hawsers and chains to the 15. without damaging it.

This time they fixed heavy metal clamps to both sides of the dish so that they could fasten the chains. The dish now had to be lifted 19. because one edge was resting against the side of the canal. The winch was again put into operation and one of the men started up the truck.
Several minutes later, the dish was successfully hauled above the surface of the water. Water streamed in torrents over its sides with such force that it set up a huge wave in the canal. There was danger that the wave would rebound off the other side of the bank and send the dish
20. the water again. By working at tremendous speed, the men managed to get the dish on to dry land before the wave returned.

C.复粒稻遗传奥秘破译


[答案] C
[解析]有机物燃烧生成水10.8 g，物质的量为＝0.6 mol，CO与CuO反应，经差量计算，得CO的质量为5.6 g，即物质的量为0.2 mol，反应后转化为0.2 mol CO2，与燃烧生成的CO2，都被碱石灰吸收。有机物含有碳原子物质的量为＝0.4 mol，有机物燃烧产物中的CO2的物质的量为0.4 mol－0.2 mol＝0.2 mol，根据碳元素守恒可知，1 mol有机物含有碳原子物质的量为2 mol，含有氢原子物质的量为6 mol。含有氧原子物质的量为＝2 mol，所以有机物的分子式为C2H6O2,0.1 mol该有机物恰好与4.6 g金属钠完全反应，4.6 g Na的物质的量＝＝0.2 mol，有机物与Na按物质的量之比1∶2反应，有机物分子中含有2个—OH，该有机物的结构简式为HOCH2CH2OH，结合有机物的结构和性质分析答案即可。
10．某有机物A的质谱图、核磁共振氢谱图如下，则A的结构简式可能为(　　)
A．HCOOH B．CH3CH2CHO
C．CH3CH2OH D．CH2===CHOCH3
[答案] C
[解析]由题图知有机物A的相对分子质量为46，有3种等效氢；HCOOH相对分子质量为46，但只有2种等效氢，A错误；CH3CH2CHO相对分子质量为58，有3种等效氢，B错误；CH3CH2OH相对分子质量为46，有3种等效氢，C正确；CH2===CHOCH3相对分子质量为58，有3种等效氢，D错误。故选C。
