Let’s listen
Boy:       What’s that strange shadow in the water?
Girl:     It looks really big. Is it an otter or a seal?
Boy:       No, it’s not an otter or a seal. It has arms - eight long arms! It’s an octopus!
Girl:     It’s a giant octopus! Wow, look! It’s chasing after a dolphin and a ray! It wants to eat them!
 
英文能力UP！
中文的「一隻」和「一條」，變成英文後統統用a / an，例如：a seal（一隻海豹）、an otter（一隻水獺）、an octopus（一隻八爪魚）、a dolphin（一條海豚）、a ray（一條魔鬼魚）。
 
Let’s learn
Indefinite articles are a and an. They mean ‘one’, referring to a single object or person.
不定冠詞有兩個：a 和 an。如果名詞的數量只有一個，我們就會把它放在名詞前面。
