听力原文：W: You look worried, David. Anything wrong (19) ？

M: Oh, it's nothing, really.

W: Are you sure？ Like to talk about it？

M: Well, to be honest, it's.., it's my mother. She… she.. how shall I put it？ She's been behaving strangely lately. Know what I mean？

W: Not quite. How？ In what way？

M: Well, you see, ever since my father died, she' s been unhappy (19) .

W: But that's normal, isn't it？ People are always upset about things like that.

M: Yes, yes. of course, that's right. But they never got on very well when my father was alive. Always arguing. I never thought she would miss him so much.

W: Oh, I see what you mean.

M: It wouldn't be so bad if she didn't live so far away. When my father retired, they moved to the seaside (20) . Then, only a year later, my father suddenly had a heart attack and just passed away (21) . Now she' s all alone in a big house by the sea, with very few friends and no family near her.

W: She must be very lonely.

M: Yes, she is! My wife and I go to see her as often as we cam But it isn't easy. I phone her at least twice a week and ask her if she' s all right or if she needs anything (22) . And that' s something else that worries me.

W: What？

M: Her memory seems to be going. I have to remind her to do all sorts of things.., to pay the gas bill, for instance. She gets annoyed with me. But I know she'll forget if I don't.

W: Well, don't worry about it too much. She's just getting old, that's all.

M: I know! That's just the problem!
