We sat in the boat waiting for Ofai．He was 1 under water．There were many beautiful shells at the bottom．If he could find some and 2 them up, he would make a lot of money．My uncle was with us．Suddenly I saw Ofai 3 his arms．I could see a large dark fish 4 under the water．“A shark(鲨鱼)!”cried my uncle．
The fish came near．Now we could see him 5 ．He was of a yellow-brown color and as big as our boat．What could we do to 6 Ofia? He had been under water more than a minute．My uncle could 7 it no longer．He took his knife and jumped into the water． 8 he went after the man-eating fish．The shark was 9 straight for Ofai．Then, suddenly, the fish turned．My uncle’s strong arm had 10 the knife deep into the side of the great fish．The water turned red as 11 ran from the shark．
Now Ofai had time to reach the top．At last he was 12 in the boat．
The fish was 13 ．He turned to come at the man who had 14 him．As he swam to my uncle, he opened his great 15 ．Again the knife went forward．This time it cut deep into the shark’s nose．
For a minute the shark lay 16 ．Now Uncle Harry could swim to the 17 ．Ofai quickly pulled him into the boat．
It wasn’t long before the shark came to life．He 18 the boat with such a hard blow⑧ that the sides were almost pushed in．We 19 as hard as possible and finally we were safe on the 20 ．
