用a whale of a time表达“快乐时光”

短语to have a whale of a time的意思是玩的非常痛快，度过了一段很开心的时光。

• I spent the summer holidays in Mexico and had a whale of a time!
• Mary is a real party girl. She goes out every night and has a whale of a time!

值得注意的是，短语size of a whale形容某人块头很大、身体过胖、体型超重。注意这是一个非礼貌用语。

• If you eat too many cakes you‘ll be the size of a whale!
