听力原文：Woman: The research for a major wildlife TV series can take up to a year, followed by about two years filming, with four or five camera teams around the world at any one time. Finding the right stories to film is only half the job. The other half is finding the right location and then going out to help the camera-person film it. This can be difficult-- you have to make sure you're in the right place at the right time. So good planning is essential. We spend a lot of time on the phone beforehand, getting advice from local experts.
You hear a woman talking on the radio about her work making wildlife films. What is her main point？
A．Being in the right place at the right time is a matter of luck.
B．More time is spent planning than actually filming.
C．It is worthwhile spending time preparing.

WA You're right on both accounts. The library has about two thousand movies, and unfortunately, there's no real browse function. But what you CAN do is to search by studio name.
MA Okay, so what would that do？

What does the man learn about the library？
A．It receives new movies each month.
B．It keeps its movies in a separate room.

听力原文：Michael: Hi! I saw you yesterday with John. We room together. I'm Michael.
Jane: Oh, hi, Mike. How are you doing？
Michael: I'm okay, but school has been really mad since I came. I haven't even had a chance to breathe!
Jane: I know. It's especially crazy when you're a freshman. Hey, what's your major？
Michael: Travel and tourism.
Jane: Well, what do you plan to do after graduation？
Michael: Uh...I really haven't decided. I think I'd like to work for a travel agency in this area. What about you？
Jane: Well, when I first started college, I majored m physics, but later I realized I might have a hard time finding a job in that field. I ended up changing to computer science. Finding a job in the IT industry shouldn't be as difficult.
Michael: Have you got a part-time job to support yourself through school？
Jane: Well, I'm on a four-year scholarship that pays my tuition.
Michael: Wow, lucky you!
Jane: Yeah, how about you？ Are you paying for school yourself？.
Michael: Sort of. I work weekends at a travel agency.
Jane: A travel agency？ That seems like a perfect experience for you ! What do you do there？
Michael: I'm a tour guide. I show tour groups around the city.
Jane: Wow, your English must be pretty good then.
Michael: Actually, they're all Chinese tourists. That's why I got the job.

M: What are you studying now？
W: l am taking three general courses and American history and American literature this semester. Last semester I took four requirements and freshman French.
M: I believe it's not too late to change your major because you've mainly taken general requirements which all freshmen have to take. Also we have twelve electives so the two literature courses will be included in them, so you can change your major without losing any credit hours.
W: I am very happy to know I am still able to change my major. I am interested in writing newspaper articles, and after finishing my degree I would like to work for some newspaper firm.
M: Oh, I think you will be a good writer.
W: Dr. Steven, when do students start practical training？
M: They don't begin practical training in reporting until the sophomore year. Journalism normally is taken in the freshman year as a general background course.
W: I see. I will take the course next semester. Thank you, very much for your help.
M: You're welcome. I look forward to seeing you in my department.
How many courses did the woman take last semester？

听力原文：M: I came to talk to you about transferring my major out of the math department.
W: Let's see. You're a sophomore now, aren't you ？ Why do you want to change majors？
M: On the final test in my calculus class I got a pretty poor score, I knew the material, but I made a small mistake early in the equation, so all the rest of the answers were wrong, too.
W: Didn't you discuss this with your instructor？
M: I didn't bother. We never got along too well. Besides, I really don't want to face this kind of pressure on every test till I graduate.
W: So what major do you want to change to？
M: I love psychology, but you need a Ph.D. to get any kind of a good job. So I thought sociology would be next best, and there is reasonable employment available for someone with a B.A.
W: Yes, that's true. And you could feasibly apply your math credits to a math minor.
M: So is it possible to change my major？
W: It seems reasonable to me, but you will need approval from the department head to get in.
(23)
A．Pass his math class.
B．Get a good job.
C．Get his degree.

Janice Weinman of the American Association of University Woman says, "Girls tend to be less comfortable than boys with the computer. They use it more for word processing rather than for problem solving, rather than to discover new ways in which to understand information."
After re-examining a thousand studies, the American Association of University women researchers found that girls make up only a small percentage of students in computer science classes. Girls consistently rate themselves significantly lower than boys in their ability and confidence in using computers. And they use computers less often than boys outside the classroom.
The instructor of this computer lab says he's, already noticed some differences. Charles Cheadle of Cesar Chavez School says, "Boys are not so afraid they might do something that will harm the computer, whereas girls are afraid they might break it somehow."
Six years ago, the software company Purple Moon noticed that girls' computer usage was falling behind boys. Karen Gould says, "The number one reason girls told us they don't like computer games is not because they're too violent, or too competitive. Girls just said they're incredibly boring."
Purple Moon says it found what girls want, characters they can relate to and story lines relative to what's going on in their own lives. Karen Gould of Purple Moon Software says, "What we definitely found from girls is there is no intrinsic (内在的) reason why they wouldn't want to play on a computer; it was just a content thing."
The sponsor of the study says it all boils down to this, the technology gender gap that separates the girls from the boys must be closed if women are to compete effectively with men in the 21st century.
In this sixth grade classroom, you would find ______.
A．only boys are allowed to use the computers
B．only girls are allowed to use the computers
C．no computers in the classroom
D．both boys and girls are allowed to use the computers
