446. So precious is time that we can't afford to waste it.
時間是如此珍貴，經不起我們浪費。

六級詞匯講解:
這是一個so…that…結果狀語從句的倒裝句，用于強調和加強語氣，正常語序應為Time is so precious that we can't afford to waste it.。“So+形容詞+be+主詞+that…”表示“如此……以至于……”，首先是so+形容詞，然后接be動詞和要形容的事物，be動詞應根據語境選擇恰當的形式，that引導從句，表示“以至于”的內容。 afford to意思是“負擔得起，買得起”。can't afford to waste sth.意為“浪費不起某物”。
