The elephant has some distant relatives called mammoths, which lived in the Stone Age. More than 15,000 years ago people painted pictures of them on cave walls. Then, astonishingly, in 1799, a man walking along the banks of the River Lena in Siberia ________________________________ (1) a startling discovery. Peering into a wall of ice, he could ________________________________ (2) see the shape of a massive,hairy mammoth, apparently ________________________________ (3) at him.He immediately ran ________________________________ (4) in terror,but several days later he ________________________________ (5) the courage to return and cut the mammoth’s tusks – its two enormous teeth – out of the ice to sell them.Mammoth tusks are the biggest teeth of any known creature, some ________________________________ (6) a length of five metres.These tusks were ________________________________ (7) to good use, protecting the mammoths' young from other animals, and brushing away snow.
