перескажите пж текст коротко по вопросам. Read the text and the sentences after it. Which of them are true? What
name can you give to the text?
Hi! My name is Bob, Bob Wilson. My holidays began yesterday.
It was a wonderful day. I was up early in the morning.
The weather was wonderful. I was happy! I went to the bathroom
and had a shower. I
dressed and went to the
kitchen. My mother gave me
breakfast — some salad,
porridge and a ham sandwich.
I drank coffee with
milk and was ready for my
morning walk with my
friends. We were all free1 —
no school, no classes.We met at the bus stop at nine and went to the cinema.
There was a good film on and we all wanted to see it. It was
“Agent [ˈeɪʤənt] Colin at the Museum1”. The film began at 9.30.
We took a bus and came to the cinema house on time. The
film was wonderful. We all liked it a lot.
After the film we went to a café near the cinema and had
lunch there. We were all hungry. We took vegetable pizza,
then drank apple, tomato and orange juices and ate ice cream.
We enjoyed our meal very much. After lunch we went to the
park and had a good time there riding our bikes. 1) Bob was up early.
2) The weather was nasty.
3) The boy’s mother gave him breakfast.
4) Bob had porridge for breakfast.
5) Bob had breakfast with his friends.
6) Bob and his friends met at the cinema.
7) The friends walked to the cinema.
8) After the film the friends were hungry.
9) They had lunch at a café.
10) After lunch they went home.-
