听力原文：M: Math department, Doctor Webster speaking.
W: Hello, Prof. Webster, this is Janet Hill calling. I lived two doors down from your teaching assistant, Don Williams. Don asked me to call you because he has lost his voice and can't talk to you himself.
M: Lost his voice？ Oh, what a shame! Is there anything I can do for him？
W: Well, he has a class this afternoon from 2: 30 to 4:00 and he won't be able to teach it. But he doesn't want to cancel it, either.
M: Does he want me to try to find somebody else to teach the class？
W: No, not exactly. What he wants to do is to get someone to go in for him, just to pass back the midterm exams. He's already marked them and they are on the desk in his office. The whole thing wouldn't take more than ten minutes.
M: His class is at 2: 30, you say？ Well, I'm free at that time and I was going to be on campus anyway; so I could do it for him. What room is his class in？
W: Cater Hall, Room two-fourteen. Will you need his office key to get the exams7 He's given it to me and I could bring it to you.
M: Actually, that won't be necessary. We have a master key in the math department. So I can get into his office if necessary.
W: Thank you very much, Prof. Webster. Don doesn't have another class to teach until Thursday, and hopefully, he will be able to talk by then. He'll call you as soon as he can. Oh, yes, I almost forget.
M: Yes？
W: Could you put the next assignment on the board, too？ It's all the problems on Page 45,and they are due at the next class.
M: No trouble at all. Thank you for passing on all the news about Don, and please tell him not to worry about anything.

听力原文： The period of engagement is the time between the marriage proposal and the wedding ceremony. Two people agree to marry, when they decided to spend their lives together. The man usually gives the woman a diamond engagement ring. That tradition is said to have started when an Austrian man gave a diamond ring to the woman he wanted to marry. The diamond represented beauty. He placed it on the third finger of her left hand. He chose that finger because it was thought that the blood vessel in that finger went directly to the heart. Today we know that this is not true, yet the tradition continues.
Americans generally are engaged for a period of about one year, if they are planning a wedding ceremony and a party. During this time, friends of the bride may hold a party at which women friends and family members give the bride gifts that she will need as a wife. These could include cooking equipment or new clothing. Friends of the man who is getting married may have a bachelor party for him. This usually takes place the night before the wedding. Only men are invited to the bachelor party.
During the marriage ceremony, the bride and her would-be husband usually exchange gold rings that represent the idea that their union will continue forever. The wife often wears both the wedding ring and the engagement ring on the same finger. The husband wears his ring on the third finger on his left hand. Many people say the purpose of the engagement period is to permit enough time to plan the wedding. But the main purpose is to let enough time pass so the two people are sure that they want to marry each other. Either person may decide to break the engagement, if this happens, the woman usually returns the ring to the man. They also return any wedding gifts they have received.
