听力原文:W: I'm all packed. (22)Take-off time is 2:30 a.m. the day after tomorrow, but I have to check-in at the airport one and half an hour earlier.
M: Who is taking you to the airport? I'd like to see you off. You need someone to keep an eye on your luggage.
W: That would be awfully nice of you. Are you sure you want to see me off at that hour of the morning?
M: (23)Of course, as long as there is enough room for me.
W: I'll call you then. I wonder what I should wear.
M: As for me, I'd wear a sports shirt and would take a jacket or sweater or something comfortable in case it got chilly on the way. For girls, honestly, I have no clue.
W: Oh, I almost forgot. (24)They will put my checked suitcases and bags in the luggage compartment on the plane and I can't get at them until I arrive at my final destination. I'll ask my mother what I should carry with me.
M: Well, my mother suggested that I should take a clean set of underwear, socks, a shirt, and slacks to put on after I land. So girls would probably need a fresh skirt and blouse plus a change of underwear.
W: That's an awesome idea. Thanks for the advice. (25)Now I just have to say goodbye to my relatives and friends. Some I have to visit or they will be very put out.

听力原文: Last semester almost half the students in my class failed. Before you get scared and conclude that I don't like my students, let explain how that came about. This class is a composition class. In composition there are certain rules of formality that must be followed in order to clearly communicate. It is unfortunate that these days many students feel that formal rules are not necessary. When 1 grade a paper and I see that you have misspelled a word, you have lost 10 points. If you have used inadequate punctuation, that can cost you up to 15 points. Additionally, any paper that you can not finish on time will not be accepted. Any theme that is not submitted on time will not be graded. You will have to read all the assignments. I will give quizzes on the reading assignments in order to make sure that you are keeping up on your readings. The class meets on Tuesday and Thursdays. Your final grade is based on the total scores of the four tests, several quizzes and six theme papers. Any time you have a problem I would seriously recommend that you come to see in my office. My office is located on the fourth floor of the building directly in front of the building we are in now. The hour is 2:00 pm to 4:00 pm on the same days as class. For Thursday you write an essay about your readings from the short story on Page 74 of the textbook. If there are no questions, that will be all for today.
