听力原文：M: Hi, Helen. I didn't expect to see you here. How is it going these days? Your face looks pale. W: Yes, I am nearly worn out, I can't stand it any more. M: What's up? W: Being a working mother is so difficult. I have to do the chores and look after the kids and husband after a hard day's work. M: I see. Well, I suggest you to think about a daycare center or hire a babysitter so that you can save some time. W: It sounds wonderful! Now I see eye to eye with you. What I am going to do first is to find a good daycare center for my little Tommy. Why did the woman's face look pale?
