In 1986， Vancouver， Canada， just marked its centennial anniversary， but the achievements made by the city in its urban development have already captured worldwide attention. To build up a city and model its economy on the basis of a harbor is the usual practice that port cities resort to for their existence and development. After a century''s construction and development， Vancouver， which boasts of a naturally-formed ice-free harbor， has become an internationally celebrated port city， operating regular ocean liners with Asia， Oceania， Europe and Latin America. Its annual cargo-handling capacity reaches 80 million tons， with one third of the city''s employed population engaged in trade and transportation business.
The glorious achievements of Vancouver is the crystallization （fruition） of the wisdom （intelligence） and the industry of the Vancouver people as a whole， including the contributions made by a diversity of ethnic minorities. Canada is a large country with a small population. Although its territory is bigger than that of China， it only has a population of less than 30 million people. Consequently， to attract and to accept foreign immigrants have become a national policy long observed by Canada. It can be safely asserted that， except for Indians， all Canadian citizens are foreign immigrants， differing only in the length of time they have settled in Canada. Vancouver， in particular， is one of the few most celebrated multi-ethnic cities in the world. At present， among the 1.8 million Vancouver residents， half of them are not native-born and one out of every four residents is from Asia. The 250，000 Chinese there have played a decisive role in facilitating the transformation of the Vancouver economy. Half of them have come to settle in Vancouver only over the past five years， making Vancouver the largest area outside Asia where the Chinese concentrate.
Section B： Translate the following underlined part of the English text into Chinese
In some societies people want children for what might be called familial reasons： to extend the family line or the family name， to propitiate the ancestors； to enable the proper functioning of religious rituals involving the family. Such reasons may seem thin in the modern， secularized society but they have been and are powerful indeed in other places.
In addition， one class of family reasons shares a border with the following category， namely， having children in order to maintain or improve a marriage： to hold the husband or occupy the wife； to repair or rejuvenate the marriage； to increase the number of children on the assumption that family happiness lies that way. The point is underlined by its converse： in some societies the failure to bear children （or males） is a threat to the marriage and a ready cause for divorce.
Beyond all that is the profound significance of children to the very institution of the family itself. To many people， husband and wife alone do not seem a proper family -they need children to enrich the circle， to validate its family character， to gather the redemptive influence of offspring. Children need the family， but the family seems also to need children， as the social institution uniquely available， at least in principle， for security， comfort， assurance， and direction in a changing， often hostile， world. To most people， such a home base， in the literal sense， needs more than one person for sustenance and in generational extension.
