1) sin35° * cos60° + cos35° * sin60° =  sin(35° + 60°) = sin95°

2) sin150° * cos80° - cos150° * sin80° =  sin(150° - 80°) = sin70°

A Day in the Life of Simon Carrot

Task I: read & comprehend the following story.

At 12: 30 pm was time for lunch. I was very hun¬gry! I sat down at the table feeling very happy because the Latin lessons were over. And then I saw what was for lunch: meat pie, boiled potatoes and cabbage. I hate vegetables! But I ate a little, because I was so hungry.

Then I went into the playground with my friends Pete Sharp and John Ford and we played football.

After lunch we had a history lesson. I don’t usually like history, but I liked this lesson very much. We learned about the Battle of Hastings in 1066. We were on holiday in Hastings last summer. I said I would bring some photographs of our holiday to school the next week.

At three o’clock it was time for my favourite lesson of the week: games. We played a very exciting game of football but it ended in a draw.

After school at four o’clock, Pete and I bought some sweets and I went to his house to listen to music.

Mum was angry because I didn’t arrive home till half past seven. She doesn`t like when I come home late. My supper was cold.

I did my French homework but I didn’t do my history homework. There was an interesting programme on television.


Task II: decide whether the following sentences are true or false, correct the false ones.

1. He had pancakes with caviar and cream for lunch.

2. He hates vegetables.

3. Simon liked a history lesson very much.

5. At two o’clock was his favourite lesson.

6. They played a very exciting game of cricket.

7. Simon went to Pete`s house to play computer games.

8. He did his math homework.


Task III: answer the following questions.

1. What is Simon`s favourite lesson?

2. Why was Simon`s mum angry?

3. Did he do his history homework? Why?
