听力原文：W: Hello？
M: Hi, May, this is Bill Johns.
W: Oh hi, Bill. You weren't in engineering class today, were you？
M: I have the flu. I was wondering if you could tell me what went on.
W: Actually we had an interesting class. Dr. Collin talked about a new type of fuel.
M: Oh, yeah？
W: Uh-hum. It's called diethyl or DME.
M: Oh, I remember reading something about DME. It's mostly used in spray cans, right？
W: Right. DME doesn't destroy the ozone, so it's been environmentally friendly.
M: But doesn't DME pollute the air if it's burned in an engine？
W: Dr. Collin says something about its exhausts being clear, that it doesn't release as much pollutants as diesel fuel, and he mentioned something about DME being more efficient than other alternative fuels.
M: When will it replace diesel fuel？
W: Not for a while. It's not economical to mass produce.
M: Well, thanks for the information. I guess I won't need to borrow your notes.
W: Well, maybe you should look at them. We are having a test next week.
M: Okay, could you give them to Mike Andrews？ I think he is in your psychology class. He is my roommate.
W: Sure. I hope you're feeling better soon.
M: Thanks. Me too. Bye!
W: Bye!

听力原文： Hidden passengers traveling in ships, trains, or even cars can be a terrible nuisance--especially when they are insects. In this respect, there is a great difference between human beings and insects. The former make every possible effort to avoid discovery, while the latter quickly draw attention to themselves.
We can only sympathize with the unfortunate man who had to stop his car soon after setting out from a country village to drive to London. Hearing a strange noise from the back of the car, he naturally got but to have a look. He examined the wheels carefully but as he found nothing wrong, he continued his way. The noise began almost immediately and now it was louder than ever. Quickly turning his head, the man saw what appeared to be a great black cloud following the car. When he stopped at a village further on, he was told that a queen bee must be hidden in his car as there were thousands of bees nearby.
On learning this, the man realized that the only way to escape would be to drive away as quickly as possible. After an hour's hard driving, he arrived in London where he parked his car outside a hotel and went in to have a drink. It was not long before a customer who had seen him arrived and hurried in to inform. him that his car was covered with bees. The poor motorist telephoned the police and explained what had happened. The police decided that the best way to deal with the situation would be to call a bee-keeper. In a short time, the bee-keeper arrived. He found the unwelcome passenger hidden near the wheels at the back of the ear. Very grateful to the motorist for his unexpected gift, the keeper took the queen and her thousands of followers home in a large box. Equally grateful, the motorist drove away in peace, at last free from the "black cloud" which had hung over his car.
