标题: 关于prep笔记1-128比较句型的一点疑惑
关于比较,摘自prep笔记1-128。
比较-主语比较
1. 对主谓宾全的句型主语比较:A do sth than B do.(AB为对等名词,加do是为了显示这是一个可以发出动作的名词,因而确定是主语,进而确定是主语对比)。时态要据后定。There be 句型等同于一般的主谓宾俱全的句型。
主语若相同,可省,但助动词不能省。如:
As a result of the continuing decline in the birth rate, [fewer people] will enter the labor force [in the 1980’s] than (people省略) did [in the 1960’s and 1970’s], a twenty-year period during which people born after the war swelled the ranks of workers.
2. 对只有主谓(如果主语有定语成分,必须要that/those来指代),没有宾语的句子,因为没有宾语,只可能有主语比较,因而不需要重复do来确认这是一个可发出动作的主语,所以其比较形式如下:
I eat faster than you.注意与下句区别 I eat apple faster than you do 如果写成 I eat apple faster than you 按GMAC的理解,从语法上就变成我吃苹果比吃你快,成了宾语比较。逻辑上显然不通。
3. 主系表结构的比较与主谓结构相同。如果时态不一致,则需补出助词,如:
The economy of Florida is more diversified than it was ten years ago

我对第二、第三点,也就是只有主谓的比较不是很理解,
如果是这样一个句子:
Apple on the tree is fresher than that on your table.
Apple on the tree is fresher than it is on your table.
究竟哪个句子是对的呢,这句话和第三点的例句有什么区别,什么时候需要使用that/those指代主语,什么时候用it?(这个问题有点傻,但是纠结了好久,希望有大大能来帮帮忙)

Apple on the tree is fresher than that on your table.正确
Apple on the tree is fresher than it is on your table.错误
这个区别在that是核心指代,that指代apple
it是全部指代,it指代Apple on the tree
第二句后半部分还原: Apple on the tree is on your table. doesn't make sense
