听力原文：W: I saw a really interesting program on TV last night. It talked about the type of things that record companies have to be careful with when they come out with new CDs.
M: What do you mean？
W: Well, they have to be very careful not to offend people -- especially parents with young kids who might buy a CD that contained violent content or used strong language.
M: How can that be avoided？
W: Well, don't you remember when that woman -- some senator's wife, I think, made a fuss over this issue？ It's not really a law, but music companies are now encouraged to put a warning label on albums that describe violence or use strong language.
M: I don't understand. Doesn't that reduce the musician's freedom of speech？
W: Not really. Musicians still have a right to free speech, but the message on the label says, "Buyer, be careful: if you get upset by violence and ugly language, don't buy this album." You agree with that, don't you？
M: I don't know. I still think the whole thing is funny and unreasonable. Musicians should have the right to say what they want to say without having to have a warning label put on their music, I mean, who gets to decide what is considered offensive and what isn't, we don't need a sticker to tell us what to do!

听力原文：When you have a dog it is necessary to care for it very carefully. In return you will be loved by your dog.
The most important part of dog-care is cleanliness. Not only does the dog have to be kept clean, but his environment should also be clean. The bed he sleeps in can be made with anything like a rug or a dog mattress.
Proper feeding is also important for your dog's health. A dog should be fed in the same place and on a regular schedule. If your dog refuses to eat, don't force him. Remove his food and don't feed him again until his next regular feeding. Food should never be left before a dog for more than 30 minutes.
One important thing that many dog owners forget is exercise for the dog. Vigorous exercise helps build strength and keeps the dog healthy. A regular walk at a fixed time of the day is enough to help a smaller dog live a healthier end happier life. Large dogs, though, require a run in an open fid&
There are other things that are also important for a dog's health — things like bathing, care of the teeth and nails, keeping them away from insects as much as possible. But if you observe the three main points covered above, your dog will give you a great amount of pleasure.
(23)

B．All day.
C．At lease 30 minutes.
D．No more than 30 minutes.

The invention of telephone has greatly eased the communication among people，but callers should be careful about when to make a phone call or it will cause embarrassments.
It is not customary to telephone someone very early in the morning in the USA. If someone is called very early in the morning，while he is shaving or having breakfast，the time of the call indicates great importance of the matter which requires immediate attention of the person called. The same implication is attached to telephone calls made after 11:00 p.m. at night. If someone receives a call during sleeping hours，he assumes it’s an urgency of life or death. The time chosen for the call communicates its importance. Time plays a very important role in our social life as you can imagine. In the USA an invitation should be sent to the guests in advance because guests usually believe that they are not highly regarded if the invitation to a dinner party is extended only three or four days before the party date. But it is not always necessarily true of the case all over the world. In some other countries，it may be taken stupid to make an appointment too far in advance because plans made for a date more than a week away tend to be forgotten. The concept of time varies in different regions of the world. Thus，misunderstandings are sometimes inevitable between men of different cultural backgrounds that treat time differently. Promptness is valued highly in America，for example. A lack of promptness is regarded as being impolite or not being fully responsible. In the US it would be incredible to keep a business partner or a guest waiting for an hour，and it would be too impolite and unacceptable by their social etiquettes. A person who is 5 minutes late is expected to give some words of explanation to the people waiting，though he might not complete his sentence.

We can make mistakes at any age. Some mistakes we make are about money. But most mistakes are about people. "Did Jerry really care when I broken up with Helen？" "When I got that great job did Jim really feel good about it, as a friend？" "Or did be envy my luck？" "And Paul-- why didn't I pick up that he was friendly just because I had a car？" When we look back, doubts like these can make us feel bad. But when we look back, it's too late.
Why do we go wrong about our friends or our enemies？ Sometimes what people say hides their real meaning. And if we don't really listen, we miss the feeling behind the words. Suppose someone tells you, "You're a lucky dog." Is he really on your side？ If he says, "You're a lucky guy" or "You're a lucky gal," that's being friendly. But "lucky dog" ？ There's a bit of envy in those words. Maybe he doesn't see it himself. But bringing in the "dog" bit puts you down a little. What be may be saying is that be doesn't think you deserve your luck.
"Just think of all the things you have to be thankful for" is another noise that says one thing and means another. It could mean that the speaker is trying to get you to see your problem as part of you life as a whole. But is he？ Wrapped up in this phrase is the thought that your problem isn't important. It's telling you to think of all the starving people in the world when you haven't got a date for Saturday night.
How can you tell the real meaning behind someone's words？ One way is to take a good look at the person talking. Do his words fit the way he looks？ Does what he says square with the tone of voice？ His posture？ The look in his eyes？ Stop and think. The minute you spend thinking about the real meaning of what people say to you may save another mistake.
Note: guy = boy; gal = girl
