These agricultural products paid to the emperor were used to finance public projects.
1.首先確定“別人的講解是：這個(gè)句子很完整,paid to the emperor 是修飾前面的 these agricultural products” 是完全正確的.這是因?yàn)?paid to the emperor 屬于過去分詞短語作后置定語,這是分詞短語的基本語法功能之一,相當(dāng)于定語從句 that were paid to the emperor,即：
These agricultural products (that were) paid to the emperor were used to finance public projects
因此僅僅認(rèn)為省略了關(guān)系詞 that 是不對(duì)的.如果非要說省略,只能說這里不僅省略了關(guān)系代詞 that,同時(shí)也省略了構(gòu)成被動(dòng)語態(tài)的助動(dòng)詞 were.
2.你把句子的意群劃分為：these agricultural products （paid to the emperor） were used to finance public projects,是對(duì)的.如果“省略修飾部分” paid to the emperor,當(dāng)然可以“暫時(shí)把它看成”：
These agricultural products were used to finance public projects.
那么,這就更加證明原句是個(gè)完整的句子,并不存在省略 that 的說法.
