Помогите ответить на вопросы:
THE TIME MACHINE Part I
One evening a prominent scientist, the author calls him Time Traveller, showed his friends a small model of a machine which he called the Time Machine. He said that he was going to send that model into the future.
Time Traveller said the big Time Machine was almost ready and that in a week's time he was going to travel into the future himself.
The next Thursday, which was the day when they usually gathered in the scientist's house, his friends came again, but they did not find the scientist at home. There was a note asking them to start dinner without him.
In the middle of the dinner the door of the dining-room opened, and the Time Traveller came in. He looked very tired. He explained to his friends that he had just returned from the remote future and told them the following story.
The Time Machine was ready at ten o'clock this morning. I sat down in the saddle.
I took the starting lever in one hand and the stopping lever in the other. Then I pressed the starting lever. I felt as if I were falling. Almost immediately I pressed the stopping lever. Looking round I saw the laboratory exactly as before. Had anything happened? Then I noticed the clock. Before I started, it had shown ten o'clock. Now it was nearly half past three.
Ответы на вопросы:
1. What is the name of the scientist?
2. What did Time Traveller show to his friends?
3. What did he explain to his friends, when he came into the dining-room in the middle of the dinner?-
