2025年仁爱英语七年级下unit6知识点

Unit 6 Topic 1 知识点一、语法精讲：there be 句型总结1、there be 句型表达某地有某物或某人，表达客观存在的这种状态，这里 there 是引导词，自身无词义，句中谓语动词 be 的人称和数量与其后的主语保持一致。 ① 肯定句：There is/are+人/物+地点(介词短语） 如：There is a pen on the desk。 There be 句型主语部分有多种名词并列时，be 动词要与邻近的主语保持一致. 即就近原则：eg: There is a pen and some books in the pencil—box。 There are some books and a pen in the pencil—box。 ② 一般疑问句：把 be 动词提前，句末加问号，肯定回答:Yes, there is/are.No, there isn't/aren’t。 如:Are there any pens in your bag? Yes, there is/are。 No， there isn’t/aren't。 ③ 否认句：直接在 be 动词后加 not：There aren't any trees in it。 ④there be 句型的特殊疑问句 A：对 there be 句型中的主语提问，常用 what’s -———，主语无论是单数还是复数，be 动词都用is，且省略 there 如：There are two desks in the room。——-—-— What’s in the room？ B：对数量提问用 How many 或 how much 语序:How many/much +be+there+地点（介词短语）？ 如:There are ten oranges in the basket.--——How many oranges are there in the basket? There is some milk in the bottle.--—-——-———How much milk is there in the bottle。2、There be 句型与 have、has 的区别： ①have、has 表达“某人或某物有…….”强调的是拥有，即某物或某人与主语是所属关系。I have a pen。 The bottle has four legs。 ②there be……表达“某地有某人或某物” Eg： There is a pen in the pencil-box./ There are some people in the park. ③ 特殊状况：My class has forty students. / My school has forty-eight classes.二、注意几种知识点1、in the tree 在树上（外来的东西） on the tree（树上自身的果实） 如： There is a cat in the tree. There are some apples on the tree。2、in front of（外部的前面） 与 in the front of ——-—（内部的前面） 如： There is a big tree in fro...
