六、七年级适用there be句型
- 1. welcome! there be 句型
- 2. 一、定义： 表达某地有某物（某人），基本句型为“there be...+某地”，其中，be动词与后面的主语保持一致。
- 3. 二、be动词的变化 is +单数可数名词/不可数名词 there be eg：There is a desk in the room. 教室里有一张桌子。 are+复数名词 eg：There are six pencils in the box.
- 4. there ____two pandas in the picture. there ____ a duck in the photo. there ____ some grass in the photo. ？there ____ a duck and two pandas in the map.？？
- 5. 牛刀小试1.There _____ some water in the bottle. A.is B.am C.are D.be 2. _____there a book on the chair? A.Is B.Are C.am D.is 3 How many people _____ there in your family? A.is B.are C.be D.was
- 6. 二、句型变化： 否定句：there be +not eg：There is not a desk in the room. 教室里有一张桌子。
- 7. 二、句型变化: 一般疑问句：把be动词提前，句末用问号； 回答时，“用什么问，就用什么答”，即 肯定回答：Yes,there is/are. 否定回答：No,there isn＇t/aren＇t. eg: Is there a desk in the room？ Yes,there is./No,there isn＇t.
- 8. 大展身手 there are pandas in the picture. there is a duck in the photo. there is some grass in the photo. 否定句： 疑问句： 肯/否定回答：
- 9. 句型转换 1.there is an elephant behind the tree.(改为一般疑问句） _____ _____ an elephant behind the tree? 2. there are some peaches on the desk.(改为否定句） _____ _____ some peaches on the desk. 3.there are some chairs in the room.(改为单数形式） _____ _____ _____ _____ in the room.
- 10. 三、就近原则 there 是个“近视眼”，若句中有几个并列主语时，be动词的形式与 离其最近的主语形式保持一致。 eg：there is a pen,three pencils,and two books in the floor; there is some milk and some apples in the fridge. ？there ____ a duck and two pandas in the map.？？
