6. This is more than the workers could stand. 這個從句沒有省略。從句謂語從此句型為SVO。Than作為關系代詞，在從句中做賓語。（than=compared with the severity of the situation which, 在從句中既表示比較概念，同時在從句中作賓語。）

7. The hotel is far more luxurious than is necessary. 這個從句中沒有省略。從句的謂語動詞句型為SVP。Than在從句中作主語。（than=compared with the degree of luxury which, 既表示比較概念，同時又在從句中表語。）

8. He drove faster than was wise. 這個從句中省略了it和to drive。還原后得到下句：

8a. He drove faster than it was wise to drive. 從句謂語動詞為SVP句型，than為關系副詞，在從句中作不定式的方式狀語。（than=compared with the speed at which， 既表示比較概念，同時又在從句中作不定式的狀語。）

通過以上分析可以看出，只要理解了than是個關系詞（關系代詞或關系副詞），必須在從句中充當一個句子成分，再結合從句的省略、替代，我們就可以還原一個結構完整的than從句，雖然在實際中這種結構完整的than從句遠不如省略成分的than從句常見。
