In 1972 a twenty-year-old medical student, Mike Jones, led a five-man canoeing expedition down the upper part of the Blue Nile. The other members of the team were Mike Hopkinson, Glen Green, Steve Nash and Dave Buikingshaw.

On 3^rd September they started out and at first everything went well, but then Glen capsized. He survived ,but the canoe was badly 21___. The next day at the Tississat Falls there was a team crisis(危机). Dave and Steve didn’t think it was 22      enough to continue. There was a long 23   and in the end the two Mikes continued in their canoes while the other three carried their equipment on land. The team 24     to meet at the second Portuguese bridge. The water in the gorge（峡谷）was very 25     and dangerous, but luckily both canoes were 26    enough to get through . Just before they reached the bridge, Mike Jones had got caught in a whirlpool（漩涡） and it had taken him several minutes to get out.

     The team met at the bridge. The canoeing was easier now, but there were other 27   . Bandits(强盗) shot at them once, but they were moving too fast. Crocodiles  were a real danger,  and one day Dave had to   28  his canoe to escape. Fortunately Steve had his 29    ready, so he shot the crocodile and got Dave’s canoe back.

   They 30   arrived at the Shafartak Bridge, tired and very tense, on 12^th September.
