It is a mouse. 它是什么？它是一只老鼠。 What are they? They are rabbits. 它们是什么？它们是兔子。 ▸ It is 缩写为 It’s，They are 缩写为 They’re。 解析：What is it? 用于询问单个事物，What are they? 用于询问两个及以上的事物，回答时单复数要对应。 一、问单数：What is it? it 指一个事物，回答用 It’s a / an + 单数名词。 例句：What is it? It’s a cat. 它是什么？它是一只猫。 二、问复数：What are they? they 指 two（两个）或两个以上的人或事物，回答用 They’re + 复数名词。 例句：What are they? They’re frogs. 它们是什么？它们是青蛙。 三、缩写形式 It is → It’s；They are → They’re。 例句：It’s cute. They’re small. 它很可爱。它们很小。 ⚠ 易错提醒：What are they? 不能用 It’s ... 回答 (✗)；They’re 的撇号不要丢！ ✎ 大显身手 一、单项选择 ( )1. — What is it? — ______ a cat. A. It’s B. They’re C.
