He was indeed a silly loon, I thought.(我想，它真是一只愚蠢的潛水鳥。)

‘Common Loon’” he reads. “It looks like a duck.”(普通潛鳥”他讀著，“看上去像鴨子。”)

Common Loon looks like a duck.(普通的潛鳥看起來像鴨子。)

Gerard van Loon thought that his father, had done "his best with material that basically bored him."(杰勒德？龍認(rèn)為他父親“在基本上令他覺得厭煩的素材上已經(jīng)盡了全力”。)

I'm no loon.(我不是笨蛋。)

He said he misses you madly, like a loon, and that dinner tonight can't come too soon.(他說他現(xiàn)在非常的想念你，已經(jīng)到了發(fā)瘋的程度，今天的晚餐為什么不能再快一點到來呢。)

To van Loon, human achievement mattered above all things.(對房龍來說，人類的成就比一切都重要。)

In the fall the loon (Colymbus glacialis) came, as usual, to moult and bathe in the pond, making the woods ring with his wild laughter before I had risen.(秋天里，潛水鳥（Colymbusglaclalis）像往常一樣來了，在湖里脫毛并且洗澡，我還沒有起身，森林里已響起了它的狂放的笑聲。)

His struggle to understand and accept his father's limitations echoes our own: he gives us a reason not to write Walter off as a hopeless loon.(他努力去理解和接受父親的缺陷，讓我們深有同感。他給出了一個理由，使我們不至于把沃爾特當(dāng)成毫無希望的瘋子。)

A more serious charge against van loon was the sloppiness of his scholarship.(對房龍的一項更嚴(yán)肅的指控是他在學(xué)問上的馬虎。)
