三年级下册考点复习U11-U12Unitll Theyre lovely句型
1.There be
一、定义表示某处存在某物/某人如翻译:书桌上有一本书There is a book on the desk.I I某物某处
二、结构+可数名词单数/不可数名词+其它.©There is
②+可数名词复数+其它.There are即动词要与后面名词的数保持一致be如There isa mapon thewall.There aretwo mapson thewall.
③当句中有两个或两个以上的名词时,动词要与跟它最靠近的名词的数保持一致,称be为就近原则如(最靠近动词)There aretwo boysand a girl under the tree.two boysbe There(最靠近动词)isagirl andtwo boysunder thetree.agirlbe
三、句型转换
①否定句在动词后加be noto如There isa bookon thedesk.f变否There isnot a bookon thedesk.缩写后变成There isnta bookon thedesk.注意肯定句中如含有在变成否定句时,要把变some,some any如There aresome bookson thedesk.f变否There arentany bookson thedesk.
②一般疑问句把动词调到句首,句号变问号beThere isa bookon thedesk.f变疑Is therea bookon thedesk注意当句中含有时,变为疑问句时,要将变为some someanyThere aresome bookson thedesk.f变疑Are thereany booksonthedesk
③特殊疑问句对可数名词的数量进行提问,用How many如(对划线部分提问)There arefive peoplein the room.一How manypeople arethere in theroom
四、与的用法区别There behave/has
①结构不同名词+其它.There be+主语其它.+have/has+
