There be 结构2023-2024学年人教版七年级英语下册

There be 结构 在英语中，There be结构是一种常见的表示“存在”的句型。本期我们主要来学习There be结构的一般现在时。请仔细观察下列各句的结构，然后补全结论部分所缺的内容。 【观察】 1. There is an English book on the desk. 2. There are four people in my family. 3. There is some milk in the glass. 4. There is a pen and some pencils in his pencil box. 5. There is not / isn’t any good news today. 6. There are not / aren’t any students in the classroom. 7. —Is there a river near the village? —Yes, there is. / No, there isn’t. 【结论】 通过观察上面的例子我们可以看出： 1. There be结构表示“某地或某时有某人或某物”，there在句中无实际意义。其中be (is / are)的形式与其后的名词(作主语)在数上要保持一致。如果be (is / are)后面是单数可数名词或不可数名词，要用______；如果be (is / are)后面是可数名词的复数形式，要用______。当be(is / are)后面有两个或者两个以上名词并列时，be(is / are)的形式通常与其后的第一个名词在数上保持一致。 2. There be结构的否定形式是在be(is / are)后加______。 3. There be结构的一般疑问句是把be (is / are)提到there前，其肯定答语为：Yes, there is / are.；否定答语为：No, there isn’t / aren’t.。  Key: 1. is; are   2. not 【温馨提示】 There be结构表示“某地或某时有某人或某物”，强调客观上的“存在”关系；而have表示“拥有”，强调主观上的“所有；占有”关系。 如： My brother has two basketballs. (表示这两个篮球属于我弟弟。) There are two basketballs on the desk. (表示桌子上存在两个篮球，而它们并不属于桌子。) Ⅰ. 按要求完成下列各题 1. My school has a new sports center. (改为同义句) _______ _______ a new sports center in my school. 2.
