http://forum.chasedream.com/dispbbs.asp ... 748&skin=01、對主謂賓全的句型主語比較:A do sth than B do.(AB為對等名詞,加do是為了顯示這是一個可以發出動作的名詞,因而確定是主語,進而確定是主語對比)。時態要據後定。There be 句型等同於一般的主謂賓俱全的句型。主語若相同,可省,但助動詞不能省。如:
As a result of the continuing decline in the birth rate, [fewer people] will enter the labor force [in the 1980』s] than (few 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、對只有主謂(如果主語有定語成分,必須要that/those來指代),沒有賓語的句子,因為沒有賓語,只可能有主語比較,因而不需要重複do來確認這是一個可發出動作的主語,所以其比較形式如下:
I eat faster than you.注意與下句區別 I eat apple faster than you do 如果寫成 I eat apple faster than you 按GMAC的理解,從語法上就變成我吃蘋果比吃你快,成了賓語比較。邏輯上顯然不通。
3、主系表結構的比較與主謂結構相同。如果時態不一致,則需補出助詞,如:
The economy of Florida is more diversified than it was ten years ago
