根据内容回答下列各题.
Not long ago, there lived in Auckland a working family who dreamed about a house of their own. Anyone then could read in the newspapers about the building companies who offered to put people into a new house 51 only a $1,000 deposit.

The couple left, sad at heart as they saw their dream house 60 . By the time they had saved the extra $1.500, no doubt the deposit would have become still higher, maybe $5,000, then $10,000 and then…!
