听力原文： Our company's offices are filled with models and gadgets that employees have built to test their ideas. We encourage this kind of creativity. We believe the best way for an engineer to test an idea is to build it. If one can get a prototype of the product to work, one can usually figure out how to scale it up and this in turn helps one to anticipate any problems one might have. We also believe fixed meetings are a waste of time. We're engineers, so if we have ideas, we need to build them and test them. Building working models feeds our creativity, which in turn fuels innovation. It also gives the client a clear example of what the final product will look like.

According to the speaker, what special items could be found in their office?

A．Prototypes

B．Games

C．Paintings

D．Printed plans

In 1901, H. G. Wells, an English writer, wrote a book describing a trip to the moon. When the explorers(探险者) landed on the moon, they discovered that the moon was full of underground cities. They expressed their surprise to the "moon people" they met. In turn, the "moon people" expressed their surprise. "Why," they asked, "are you traveling to outer space when you don't even use your inner space?"

H. G. Wells could only imagine travel to the moon. In 1969, human beings really did land on the moon. People today know that there are no underground cities on the moon. However, the question that the "moon people" asked is still an interesting one. A growing number of scientists are seriously thinking about it.

Underground systems are already in place. Many cities have underground car parks. In some cities, such as Tokyo, Seoul and Montreal, there are large underground shopping areas.

The "Chunnel", a tunnel(隧道) connecting England and France, is now complete. But what about underground cities? Japan's Taisei Corporation is designing a network of underground systems, called "Alice Cities". The designers imagine using surface space for public parks and using underground space for fiats, offices, shopping, and so on. A solar dome (太阳能穹顶) would cover the whole city.

Supporters of underground development say that building down rather than building up is a good way to use the earth's space. The surface, they say, can be used for farms, parks, gardens, and wilderness. H.G. Wells's "moon people" would agree. Would you?

The explorers in H. G. Wells's story were surprised to find that the "moon people"

A．knew so much about the earth

B．understood their language

C．lived in so many underground cities

D．were ahead of them in space technology

M: You know all the classes we've missed because of the snow?

W: Uh oh ....

M: Yup-we're going to have to make them up and the dean says it will have to be during spring break.

W: Sam! We have our-vacation all set! What are we going to do? Do the others know?

W: You think they'll excuse us from class?

M: Probably not. But I was talking to Mark this morning and he said that one of his professors told him that they could make up the class at a different time.

W: Wow--that's great! Which professor was it?

M: I don't know. But we're going to have to speak to all of them anyway.

W: Why didn't they add extra days at the end of the semester before summer classes?

M: Because of the graduation date, which can't be changed.

W: Are other colleges around here doing the same thing?

M: I would imagine set---it's been such a bad winter and we've missed too many classes. We do really need to make them up.

W: I know, I know. I was just really looking forward to this vacation. The idea of the sun and the beach!
