听力原文：M: Hi, Susan. Where have you been?

W: Hi, David. I was just at the library. I have to hand in my biology paper tomorrow.

M: Tomorrow? Oh, no[ I thought it wasn't due until next week.

W: Oh. Don't worry. It is due next Tuesday. But I'm going away for the weekend and won't be back till Monday night.

M: Oh, where are you going?

W: Philadelphia. We're having a family reunion. It's my grandmother's eightieth birthday.

M: Great! How many people will be there?

W: Around sixty.

M: It seems that your family are pretty close.

W: You said it. So have you started working on your biology paper?

M: Yeah. I'm doing it on bees and how they're able to recognize whether another bee is related to them.

W: How can they tell?

M: They use their sense of smell. The bees guard their nests this way. If another bee approaches the nest, the guard determines if the new bee is familiar. If it is, it's allowed to enter.

W: Sounds interesting. Can other insects do this?

M: Well, as far as I am concerned, some wasps can. Each wasp nest has a special combination of plant fibers and so the wasps that live there have a unique smell.

W: Urn, it sounds like that the bees are picky about who comes to their family reunion.

A．They're roommates.

B．They're classmates.

C．They're cousins.

D．They're lab partners.

American's city dwellers are a mobile people. The decennial censuses provide documentation in their redundant accounts of rapid changes and growth in most of our great cities. But statistical evidence is hardly needed. The changes in our cities have occurred so rapidly that the perception of mobility is an integral formed in the intervals between visits. The neighbour-hoods of our childhood present alien appearances and the landmarks that anchored our memories have disappeared.

How do these dramatic changes in residential areas come about? In part, industry and commerce in their expansion encroach upon land used for residence. But, in larger part, the changes are mass movements of families--the end results of countless thousands of residence shifts made by urban Americans every year. Compound in the mass, the residence shifts of urban households produce most of the change and flux of urban population structures.

Some of the mobility is an expression of the growth of our population. Every new family started ordinarily means another household formed. The mobility that occurs is much greater than can be accounted for only by an addition of new households to our population. The high level of mobility implies that established households are involved in a large-scale game of "musical chairs" in which housing is exchanged from time to time.

Residential shifts often accompany the dissolution of households, although not as consistently as in the case of the formations of new households. A divorce or separation forces at least one to move, and often both husband and wife Shift residence. Morality sometimes precipitates a move on the part of the remaining members of the household. But, neither divorce nor morality, when added to new household formation, can account for more than a very small part of the American mobility rate.

Another part of the high residential mobility rate might be traced to changes occurring in the labour force. American workers change jobs frequently and some of the residential mobility might be viewed as consequence of job shifts that do not involve long-distance movements. About three fourths of such shifts do not cross country boundaries and many of them take place within smaller areas. Neither can job shifts account for the overall picture of mobility, much of which is a kind of "milling out" within small areas of the city.

The phrase "encroach upon" in Paragraph 2 most probably means ______.

A．buy and sell

B．measure and survey

C．invade and occupy

D．rent and share
