小升初精讲精练(第七讲——There be句型)
第七讲There be句型专项练习概念回顾：1.There be句型表示：某处有某物（某人）。
基本句型为:（1）There is+名词单数/不可数名词+某地或某时。
( 2 ) There are+名词复数+某地/某时.2.特别注意：There be句型的“就近原则”——当There be后面所接的物有多个时，谓语动词be要根据最靠近它的那个名词的单复数来确定，即就近原则如：There is a pen, two books and many pencils on the desk.在本句中尽管有钢笔、书和铅笔，但是由于离be动词最近的一项是单数a pen，因此，be动词用单数is。
3.There be句型变否定句：在be动词之后加not，some变any。
（not a/an/any = no）4. There be 变一般疑问句：把be动词提前句首，some变any，一二人称互换。
（I/we---you, my/our---your）回答时：肯定（Yes, there is/ Yes, there are）否定（No, there isn’t/No, there aren’t）5. There be特殊疑问句（划线部分提问）：特殊疑问词+一般疑问句？注意一二人称互换（I / we ←→you , my / our ←→your）特殊情况1——There be 句型中的数量提问的基本结构是(How many +名词复数+ are there＋介词短语？)（必须用are there提问，回答时根据单复数情况回答）例如：（1）How many birds are there in the picture ?图片中有多少只小鸟?---There is one bird in the picture.有一只鸟在图中。
（2）How many pens do you have? 你有多少钢笔？---I have a pen.我有一支钢笔。

小升初英语考点 记忆顺口溜
小升初英语考点记忆顺口溜1、祈使句记忆顺口溜祈使句无主语，主语you常省去。
动词原形谓语当，句首Don't变否定。
朗读应当用降调，句末常标感叹号。
2、形容词比较级顺口溜比较级是形容词，一好一坏要记牢，good更好是better, bad更坏是worse结尾有e只加r，nice变成nicer；双写目前有三个，bigger, fatter 和hotter其余全部加er。
3、be的用法口诀我用am，你用are，is连着他，她，它；单数名词用is，复数名词全用are。
变疑问，往前提，句末问号莫丢弃。
变否定，更容易，be后not莫忘记。
疑问否定任你变，句首大写莫迟疑。
4、时间名词前所用介词的速记歌年月周前要用in，日子前面却不行。
遇到几号要用on，上午下午又是in。
要说某日上下午，用on换in才能行。
午夜黄昏须用at，黎明用它也不错。
at也用在明分前，说“差”可要用上to，说“过”只可使用past，多说多练牢牢记，莫让岁月空蹉跎。
5、记住f(e)结尾的名词复数妻子持刀去宰狼，小偷吓得发了慌；躲在架后保己命，半片树叶遮目光。
也可以说：小偷的妻子用小刀和树叶把狼劈成了两半。
(thief-thieves, wife-wives, knife-knives,leaf-leaves, wolf-wolves, half-halves)6、非谓语动词后接动词不定式做宾语补足语省略不定式符号“to”（也就是我们说的接动词原形）的一些常用特殊动词一些动词要掌握，have, let和make,此三动词是使役，“注意”“观察”“听到”see，还有feel和watch，使用它们要仔细，后接“宾补”略去“to”，此点千万要牢记除此之外，还可以掌握“八字言”，一感feel,二听hear, listen to,三让have, let, make,四看see, look at, observe, watch7、There be句型用法口诀There be句型有特点，主语放在be后边。

There be 句型1. 定义：There be句型表示某处存在某物或某人。
2. 结构：(1) There is +单数可数名词/不可数名词+ 地点状语.(2) There are +复数名词+地点状语.there是引导词，在句中不充当任何成分，翻译时也不必译出。
句子的主语是某人或某物，谓语动词be要与主语（某人或某物）的数保持一致。
当主语是两个或两个以上的名词时，谓语动词要与跟它最近的那个名词一致。
eg. ① There is a bird in the tree. 树上有一只鸟。
② There is a teacher and many students in our classroom. 我们教室里有一位老师和许多学生。
③ There are two boys and a girl under the tree. 树下有两个男孩，一个女孩。
3. There be句型与have的区别：(1) There be 句型和have都表示“有”的含义。
区别如下：There be表示“某处存在某物或某人”；have 表示“某人拥有某物/某人”，它表示所有、拥有关系。
eg.①He has two sons. 他有两个儿子。
②There are two men in the office. 办公室里有两个男人。
(2)当have表示“包括”、“存在”的含义时，There be 句型与其可互换。
eg. A week has seven days. =There are seven days in a week. 一个星期有七天。
