• Expect sb to do sth 期盼……做……，to do sth 为不定式做宾语补语，其被结构为：be expected to do.
• to live , to marry ,to continue 为平行结构，都是做expect的宾语补语，其中to marry 的宾语people后面还带了一个定语从句。
• In our society, however, young people often travel great distances for their education, move out （搬出）of the family home at an early age, marry or live with people whom their parents have never met, and choose occupations different from those of their parents.
• 本句中travel，move out ，marry or live，choose为平行结构，当有几个并列成分时，前面几个可以用逗号连接，最后一个用and连接。
• whom their parents have never met为定语从句，先行词为people。
• In our upwardly（上升的） mobile（移动的） society, parents often expect their children to do better than they did: to find better jobs, to make more money, and to do all the things that they were unable to do.
• Often, however, the ambitions（抱负） that parents have for their children （定从）are another cause of the division（分歧） between them. Often, they discover that they have very little in common with （与……相同）each other. Finally, the speed at which changes take place in our society （定从）is another cause of the generation gap.
• In a traditional culture（文化）, elderly（上了年纪的）people are valued for their wisdom（智慧）, but in our society the knowledge of a lifetime may become obsolete（过时的） overnight（一夜之间的，形容很快的）.
