Well, Mrs. Evans, I’ve done my best to look after David. I’ve tidied his room up every day, got him a meal together whenever he needed one and made sure he’s always had a clean shirt to put on. It’s not been easy, with two of my own to worry about, as well. David had the best of attention, I must say. But now because I asked him to give up bringing that American friend to his home he has got quite miserable and unfriendly. He comes in at all hours and his behavior---- well, it’s quite hard to put up with---- and it’s all because of this friend. I’m sure he’s a bad influence. You see, David’s a visitor and doesn’t fully understand our ways.

He used to study most evenings. He’s got through quite a bit of work. He did up his room quite nicely, with bookshelves and large posters. He’d ask Mr. Smith and me up for a drink and cheer us up with songs from his country. He’s very good at the guitar, you know.

I don’t want to appear as if I’m running after him, but it’s about time we made it up. I’m sure he’s upset because I told him off. It might be a good idea to take him out for a meal, perhaps even with his friend. I don’t know whether it will do any good but we can try. I’m glad I’ve had this little chat with you, Mrs. Evans, and I’ll let you know how I get on.

A. Mr. Smith                                       B. too much homework

C. David’s behavior                              D. David’s friend

2. Mrs. Smith wants to make up the quarrel by _______.

A. cooking a meal                                B. inviting David and his friend out

C. running after David                          D. giving them drinks

3. David’s present attitude to Mrs. Smith is ________.

A. unfriendly             B. cheerful      C. very attentive         D. incomprehensible

4. David is ________.

A. an American friend     B. a singer   C. a visiting student             D. Mrs. Smith’s son
