三年级英语:There be 句型——描述身边的事物

There be 句型——描述身边的事物

什么是 There be 句型?

当我们想说"某处有某物"时,英语里最常用的就是 There be 句型。

基本结构: There is/are + 某物 + 某处

一、is 还是 are?

There is + 单数名词/不可数名词

  • ✅ There is a book on the desk. (桌子上有一本书。)
  • ✅ There is some water in the cup. (杯子里有一些水。)

There are + 复数名词

  • ✅ There are three pencils in the bag. (书包里有三支铅笔。)
  • ✅ There are many flowers in the garden. (花园里有很多花。)

有多个物品时:就近原则!

当There be后面有多个名词时,be动词要和离它最近的名词保持一致。

例题1: There ___ a pen and two rulers on the table. - 离be最近的是"a pen"(单数),所以用 is

例题2: There ___ two rulers and a pen on the table. - 离be最近的是"two rulers"(复数),所以用 are

二、否定句和疑问句

否定句:在be动词后加 not

  • There is not (isn't) a dog in the room.
  • There are not (aren't) any apples on the tree.

一般疑问句:把be动词提到句首

  • Is there a library near here? — Yes, there is. / No, there isn't.
  • Are there any birds in the tree? — Yes, there are. / No, there aren't.

三、实战对话

Tom: Look! There is a new playground in our school! Amy: Oh, really? Are there any swings? Tom: Yes, there are. There are two big swings and a slide. Amy: Great! There is also a basketball court, right? Tom: No, there isn't. But there is a football field.

四、常见错误 ❌

  3. 忘记就近原则 — ✗ There are a pen and three books. → ✓ There is a pen and three books.
