Read the text and answer six questions.

Helen's eyes were not very good, so she usually wore glasses. But when she was seventeen and she began to go out with a young man, she never wore her glasses when she was with him.
When he came to the door to take her out, she took her glasses off, and when she came home again and he left, she put them on.
One day her mother said to her, 'But Helen, why do you never wear your glasses when you are with Jim? He takes you to beautiful places in his car, but you don't see anything.' 'Well, Mother,' said Helen, 'I look prettier to Jim when I am not wearing my glasses- and he looks better to me too!'
