【问】 No wonder he knew so much about it.难怪他对此事了解很多。(《新英汉辞典》，P.1625)请问如何分析这个句子?

【答】 No(Little，Small)wonder是It’s no(little，small)wonder that的省略形式。it和that从句是同位语关系，也就是说that从句是主语从句(连词that常常省略)：

1. No wonder you were so late.

难怪你来得这么迟。

2. No wonder you can't sleep when you eat so much.

你吃这么多睡不着觉，那是毫不奇怪的。

3. Small wonder that they refused the offer!

怪不得他们拒绝这个建议!

A. No wonder B. No doubt
