*   **语法结构：** `There + be + 主语 + (状语/地点状语/时间状语)`

## II. be动词的选用

*   **规则：** be动词的形式要与真正的主语保持一致，而不是与there一致。
*   **单数主语：** `is/was`
    *   例子：There is a cat on the mat.
    *   例子：There was a great storm last night.
*   **复数主语：** `are/were`
    *   例子：There are many students in the classroom.

    *   多个单数主语并列，通常用`is/was`，但在非正式语境中，`are/were`也可接受。
