OG60 "be of"结构

AMBER513

That sentence doesn't really cut it. Here's why:

The correct choice in the original post has a very clear parallel structure: is still a goal of a majority of young adults, as it was (a goal) of earlier generations. Because of the strong parallelism, there's nothing else that the end phrase could possibly refer to.

In your most recent sentence, however, 'that of earlier generations' is a problem. Specifically, 'that of' doesn't have a clear referent, because there's no strong parallel structure to determine it anymore. It could conceivably stand for 'goal', 'majority', or perhaps even 'freestanding house' or 'land'. And if you go by the best possible parallelism, 'that of' seems to refer to a majority, because that's the word placed right before '...OF young adults' (which seems to work in parallel with '...OF earlier generations').

RON的意思还是省略

AMBER513

这里比较的是owning and living in a freestanding house on its own land is still a goal of a majority of young adults这整个事实，而不是goal，而且这里that是不是指代goal也有歧义，所以A是不能选的
