what could be nicer than有哪些用途剖析

The warm weather outside may look perfect for outdoor exercise. But for those who are not that sporty, what could be nicer than having a relaxing afternoon tea with a few good friends and taking a break from studying.

老師，這邊what could be nicer than，有點看不明白，為何不能是it could be nicer than?



網友的句子，最后應該是個特殊疑問句，須加問號。

The warm weather outside may look perfect for outdoor exercise. But for those who are not that sporty, what could be nicer than having a relaxing afternoon tea with a few good friends and taking a break from studying?

【翻譯】室外暖和的天氣看著非常合適戶外運動。但對于那些不那樣喜歡運動的人來講，還有哪些比和幾個好朋友喝一杯輕松的下午茶，與離開學習休息一會兒更好呢？



我把這個特殊疑問句變成陳述句，能夠幫助網友理解：

1. nothing could be nicer than having a relaxing afternoon tea with a few good friends and taking a break from studying.

2. 這個句子是個含有比較從句的復合句：

主句：nothing could be nicer

比較從句：than having a relaxing afternoon tea with a few good friends and taking a break from studying

3. 在比較從句中，兩個并列的動名詞短語作主語，后面省略了could be。

4. could 表示“推斷”。
