This morning, however, a fireman accidentally discovered the cause. He noticed the     1     of a snake which was wound round the electric wires of a 16,000-volt power line. In this way, he was able to solve the mystery. The     2     was simple but very unusual. A bird had snatched up the snake from the ground and then     3     it on to the wires.

We have just moved into a new house and I have been working hard all morning. I have been trying to get my new room     1    . This has not been easy because I own over a thousand books. To make matters worse, the room is rather small, so I have temporarily put my books on the floor. A short while ago, my sister helped me to carry one of my old bookcases up the stairs. She went into my room and got a big surprise     2     she saw all those books on the floor. This is the     3     carpet I have ever seen, she said.

(Unit 3) “Just relax, since there is nothing planned on the     1     today. Tomorrow you’ll be ready for some visits.” Having said this, he spread some food on the table, and     2     a bed from the floor. After he left, I had a bried meal and a hot bath.     3     , I slid into bed and fell fast asleep.

(Unit 4) You need to be curious. Only if you ask many questions will you     4     all the information you need to know. We say a good journalist must have a good “nose” for a story. That means you must be able to     5     when people are not telling the whole truth and then try to discover it. They must use research to     6     themselves of the missing part of the story.

(Unit 5)     7     clothing using     8     if necessary unless it is stuck to the burn. Take off other clothing and jewellery near the burn.

(Unit 5) Cool burns immediately with cool but not icy water. It’s best to place burns under gently running water for about 10 minutes. (The cool water stops the burning process, prevents the pain becoming     9     and reduces     10    .) Do not put cold water on third degree burns.

Private Conversation

Last week I went to the theatre. I had a very good seat. The play was very     1    . I did not enjoy it. A young man and a young woman were sitting       2     me. They were talking     3    . I got very angry. I could not hear the actors. I turned round. I looked at the man and the woman angrily. They did not     4     any attention.

Please send me a card

Postcards always spoil my holidays. Last summer, I went to Italy. I     5    museums and sat in public gardens. A     6     waiter taught me a few words of Italian. Then he lent me a book. I read a few lines, but I did not     7     a word. Everyday I thought about postcards.

I have just moved to a house in Bridge Street. Yesterday a beggar     8     at my door. He asked me for a meal and a glass of beer. In     9     for this, the beggar stood on his head and sang songs. I gave him a meal. He ate the food and     10     the beer. Then he put a piece of cheese in his pocket and went away.

Over time I have been changed quite a lot. I began as a     1     machine in France in 1642. Although I was young I could     2     difficult sums. I developed very slowly and it     3     nearly two hundred years before I was built as an analytical machine by Charles Babbage. After I was     4     by an operator who used cards with holes, I could “think”

    5     and produce an answer quicker than any person. At that time it was     6     a technological revolution and the start of my “    7     intelligence”.

Dinosaurs did out suddenly about 65 million years ago. Some scientists think it came after an unexpected     1     when a huge rock from space     2     the earth and put too much dust into the air.     3     think the earth got too hot for the dinosaurs to live on any more.
