Robinson Crusoe
My name is Robinson Crusoe and I was born in the city of York. I always
wanted to go to sea. One day, when I was eighteen years old, I went to Hull.
(1)______ The boy’s father was the captain of a ship. That boy said to me, ‘Rob, do
you want to sail on our ship? We start to London today.’
I was very glad, of course, and agreed at once.
In the open sea we were caught in a terrible storm. (2)_______ Finally it went
to the bottom and we were all thrown into the sea. A ship which was passing by sent
a boat and saved us. In the morning we reached the shore.
I was very young then and soon forgot the terrible storm. (3)______ I went to
London. There I met the captain of a ship that was going to Africa. The captain was a
very nice gentleman. We liked each other and soon became friends. The captain
invited me to sail to Africa with him. Of course, I agreed with pleasure.
The voyage to Africa was successful. But when we came back to England, the
captain died, and I had to go on my second voyage to Africa without my friend.
(4)______ The weather was fine and the sea was calm. But not far from the
shores of Africa we met a ship with a black flag. It was a pirate ship, and the pirates
attacked us. Our sailors fought bravely, but the pirates were stronger. Some of our
men were killed, and the others were taken prisoner. When the pirate ship came to the
port, the captain took me to his house and made me his slave.
(5)______ I had to work in the house and in the yard with the other slaves. It
was quite impossible to run away
