4、om.我们教室里有一位老师和许多学生。 There are two boys and a girl under the tree. 树下有两个男孩，一个女孩。【考察点】二there be 句型的各种句型转化。1.变成否认There be句型的否认式的构成和含有be动词的其它句型一样，在be后加上not或no即可。注意not和no的不同：not是副词，no为形容词，not a/an/any + n. 相当于no+ n.。 如： There are some pictures on the wall. There aren't any pictures on the wall. =Ther

5、e are no pictures on the wall. There is a bike behind the tree. There isn't a bike behind the tree. =There is no bike behind the tree.2.变成一般疑问句 There be句型的一般疑问句变化是把be动词调整到句首，再在句尾加上问号即可。但同时要注意：当肯定句中有some时，要将其改为any否认变化也一样。如：There is some water on Mars. Is there any water on Mars? There are some fi

6、sh in the water. Are there any fish in the water? 3.特殊疑问句1对主语提问：当主语是人的时候，那么用who 引导，当主语是物的时候，那么用what 引导。注意：无论原句的主语是单数还是复数，对之提问时一般都用be的单数形式答复时却要根据实际情况来决定。如： There are many things over there. What's over there? There is a little girl in the room.Who is in the room? 2对地点状语提问：那么用where 引导。如： There is

7、a computer on the desk. Where is the computer? There are four children on the playground. Where are the four children? 3对数量提问,一般有两种句型构造： How many+复数名词+are there+介词短语？ How much+不可数名词+is there+介词短语？【考察点】三there be 句型的时态。 be可以有如今时there is/are、过去时there was/were、将来时there is/are going to be或there will be和完

8、成时there have/has been；还可用there must be ,there cant be, there used to be等。 如： -There is going to /will be a concert this evening. -Yeah. Exciting news! There is going to / will be a football match on TV this evening. 【考察点】四there be 句型的主谓一致 There be 构造中的be动词要和后面所跟名词保持一致,遵循就近原那么。 如：There isnany rice in

10、/某人，它表示所有、拥有关系。 如： He has two sons. 他有两个儿子。There 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。如： A week has seven days. =There are seven days in a week. 一个星期有七天。三、例题精析【例题1】【题干】David, there _ a dictionary and some books on your desk.

18、然。我抓住练胆这个关键，面向全体，偏向差生。一是和幼儿建立和谐的语言交流关系。每当和幼儿讲话时，我总是笑脸相迎，声音亲切，动作亲昵，消除幼儿畏惧心理，让他能主动的、无拘无束地和我交谈。二是注重培养幼儿敢于当众说话的习惯。或在课堂教学中，改变过去老师讲学生听的传统的教学形式，取消了先举手后发言的约束，多采取自由讨论和谈话的形式，给每个幼儿较多的当众说话的时机，培养幼儿爱说话敢说话的兴趣，对一些说话有困难的幼儿，我总是认真地耐心地听，热情地帮助和鼓励他把话说完、说好，增强其说话的勇气和把话说好的信心。三是要提明确的说话要求，在说话训练中不断进步，我要求每个幼儿在说话时要仪态大方，口齿清楚，声音响亮

19、，学会用眼神。对说得好的幼儿，即使是某一方面，我都抓住教育，提出表扬，并要其他幼儿模拟。长期坚持，不断训练，幼儿说话胆量也在不断进步。 4.How much milk is there in the glass?课本、报刊杂志中的成语、名言警句等俯首皆是,但学生写作文运用到文章中的甚少,即使运用也很难做到恰如其分。为什么?还是没有彻底“记死的缘故。要解决这个问题,方法很简单,每天花3-5分钟左右的时间记一条成语、一那么名言警句即可。可以写在后黑板的“积累专栏上每日一换,可以在每天课前的3分钟让学生轮流讲解,也可让学生个人搜集,每天往笔记本上抄写,老师定期检查等等。这样,一年就可记300多条成语

20、、300多那么名言警句,日积月累,终究会成为一笔不小的财富。这些成语典故“贮藏在学生脑中,自然会出口成章,写作时便会随心所欲地“提取出来,使文章增色添辉。【稳固】1.A 考察There is +单数可数名词/不可数名词+ 地点状语.2.C 考察There be句型表示“某地有某物或“某时有某人；have“有，指人有，故答案为C死记硬背是一种传统的教学方式,在我国有悠久的历史。但随着素质教育的开展,死记硬背被作为一种僵化的、阻碍学生才能开展的教学方式,渐渐为人们所摒弃;而另一方面,老师们又为进步学生的语文素养煞费苦心。其实,只要应用得当,“死记硬背与进步学生素质并不矛盾。相反,它恰是进步学生语文
