听力原文： Some people have very good memories, and can easily learn quite long poems by heart. There are other people who can only remember things when they have said them over and over.

A good memory is a great help in learning a language. Everybody learns his own language by remembering what he hears when he is a small child, and some children seem to learn two languages almost as easily as one. In school it is not so easy to learn a second language because the pupils have so little time for it, and they are busy with other subjects as well.

A man's mind is rather like a camera, but it takes photos not only of what we see but of what we feel, hear, smell and taste. When we take a real photo with a camera, there is much to do before the photo is finished and ready to show to our friends. In the same way there is much work to be done before we can keep a picture forever in our minds.

There are two kinds of people according to the narrator, one kind of people can learn things quickly, but the other kind of people _______.

A．can never remember a long poem

B．can remember but it takes longer for them

C．can only remember short passage

D．always forget people's names

Section B

听力原文： Requesting someone's business card is a straightforward process. You need only say, "Do you have a business card？" or "May I have your business card？" When you want to present your own card, you can say, "Here's my card. Please feel free to call me if you have any suggestions." If you wish to offer your card to a long-time associate, you can say, "Did I ever give you my card？" or "I mean to give you my card." [26]It's not polite to directly refuse a request from someone for your business card. Instead, you can say, "Sorry, but I'm afraid I'm all out at the moment." or "I neglected to bring them with me." Giving someone your card, of course, does not obligate you to continue contact, nor does accepting someone else's card. [27]When you do receive a card, say "Thank you." and examine it briefly before putting it away. [28]You can use a business card that you received to refresh your memory about someone's name and title before your next meeting. You can also record notes about the meeting on the back of the card, or place it in your card file.

(27)

A．Requesting one's business card directly.

B．Accepting one's card but not continuing contact with him.

C．Putting one's business card in the card file.

D．Refusing a request for your business card directly.
