I cannot imagine the modern society without computers. We used to it so much. Someone can say that teenagers are hinge on computers,gadgets  and do not see anything except that. But I guess this is wrong opinion. Because this is so helpful thing! 40 years ago people hadn`t opportunity to find any data in few minutes. To have a chat without letters. We write texts, draw with computers! We actually find friends with the internet. People use computers in architecture for construction drawings, and in many other things. Lets give a respect for computers!

After I had been walking for an hour, I decided to have a rest.
Mary could see that the child had been crying for some time.
I thought he needed some fresh air. He had been sitting there reading all morning.
When I saw the mess my paper was in, it was obvious that someone read it.
She finally said: "Yes”. He had been asking her to marry him for years.
The manager went down with pneumonia. He had been looking unwell for several days.
He went to see a doctor. He had been feeling ill for several days.
His sister had been living in that place for 5 years when the war broke down.
Mrs Oliver said she had been reading since morning the day before but actually she had been watching her neighbors through binoculars.
She felt chilly after she had been swimming for an hour and a half.
At last I found the book which I had been looking for all day.
