定义 / 说明
我们用 there is 和 there are 表示某物存在或可用。这个结构用于引入某个地方“有什么”，而不是直接描述事物本身。there is 搭配单数名词，there are 搭配复数名词。它在谈房间、城镇、食物、家具和日常场景时非常常见。
关键规则
- 单数名词用 there is：There is a chair.
- 复数名词用 there are：There are two chairs.
- 真正的主语在 there is/are 后面。
- 需要时使用 a/an 或数字：There is a park. / There are three parks.
- 这个结构后面常接地点短语：There is a cafe near here.
