有好多 idioms 都有動物名子喺入面，但未必真係關隻動物事！
1. Dog days of summer
出處：夏天成日見到狗狗伸條俐出黎散熱，可能就因為咁用 ”dog days of summer” 嚟形容酷熱天。
e.g. The dog days of summer are just around the corner.
好快就到酷熱期。
2. He has seen the elephant
呢句唔係話佢見過大笨象咁解！係指佢見過世面～
e.g. He has a range of experiences, good and bad, in his life. He has seen the elephant.
他人生經驗豐富，好的壞的都遇過，是見過世面的人。
3. Kill the goose that lays the golden egg
就咁睇字面意思以為係「殺左隻藏金蛋嘅鵝」？
諗真啲，係咪覺得有個中文成語近乎呢個意思？無錯！真正意思係「殺雞取卵」～
e.g. If the government tighten visa regulations for tourists entering Hong Kong, they would kill the goose that lays the golden egg.
如政府收緊來港遊客的簽證申請，真的是殺雞取卵了。
4. When Pigs Fly
當面對住覺得無可能會發生嘅事，我地會講「哈哈！佢會XXX，豬乸會上樹啦！」
同樣 ”When Pigs Fly” 用豬黎形容不可能嘅事情！
e.g. 朋友A：I’ll wake up at 6am on Sunday to clean my room.
你：Yes, you’ll do that when pigs fly!
5. Crocodile tears
鱷魚都會流眼淚？
相傳鱷魚會發出一啲扮喊嘅聲音嚟引誘獵物，得手後就一路食一路流眼淚。
所以 crocodile tears 同中文嘅歇後語「貓哭老鼠假慈悲」有近似意思。
e.g. Don’t shed crocodile tears over his death, it makes me sick.
不要為他的死假裝悲傷地哭，這讓我感到噁心。
