知识清单·译林版四年级下册 Unit2 Helping others at school 知识梳理 知识点拨 【考点一】1.there be句型的一般疑问句及回答 【考点二】2.序数词(first,second,third)的用法 【考点三】3.help的常用搭配 【考点四】4.字母 “i” 的发音 /ɪ/ 考点一：there be 句型的一般疑问句及回答 解析：there be 句型的一般疑问句,用于表达某地有某人或某物吗？在这个句型中，要根据后面名词的单复数选择“is”或“are”,疑问句中复数名词前用“any”(表示“一些”)。 结构：若是单数名词Is there+a/an+单数名词+地点? 例 如 ：Is there a piano in the music room?音乐室里有钢琴吗? 若是复数名词：Are there+any+复数名词+地点? 例 如 ：Are there any classrooms on the second floor?二楼有教室吗? 肯定回答：Yes,there is. (单数)/Yes,there are. (复数) 否定回答：No,there isn't. (单数)/No,there aren't. (复数) · 注意：there be句型的一般疑问句修改方法： ①找出be动词 (is,am,are)。 ②将be动词 (is,am,are)提前 。 ③有some变为any。 ④第一人称变为第二人称,I/we变为you,my/your变为your,me/us变为you 例：There are some girls in the room.(改为一般疑问句，并作出回答) —Are there any girls in the room? —Yes,there are./No,there aren't. · 拓展：常用的there be 句型的特殊疑问句： 一、询问某处物品的数量：How many+可数名词复数+are there +地点？或How much+不可数名词+is there +地点？ 二、询问某处存在或包含什么物品：What’s+地点？ 例：How many pencils are there in the pencil case?在铅笔袋里有多少支铅笔啊？ What’s in the schoolbag?书包里有什么？ 【大显身手】 1、 按要求改写句子。 1.There is some bread in the bag.（改为一般疑问句并作否定回答） ________ _______ _______ bread in the bag? No， __________ ________. 2. There are some pictures on the wall. （对划线部分提问） ________ on the wall? 3.There is one playground in our school.(对画线部分提问) ________ ________playgrounds________ ________in your school? 4.Are there any pens on the desk?(改为陈述句) ________are________pens on the desk. 5.There are some students in the park.(改为一般疑问句，并作肯定回答） ________ ________ ________students in the park?________,there________. 考点二：序数词(first,second,third)的用法 解析：数词主要分为基数词和序数词两类。基数词表示数量多少的词，用来回答“有几个”“多少”的问题，简单说：就是我们平时数数用的数。如：one 、two、 three，而序数词表示顺序、位置的词，用来回答“第几个”的问题。简单说：序数词是表示顺序的数，通常带“第”字。如：first、second、third 例：I have five books. 我有五本书。 We live on the third floor. 我们住在三楼（序数词）。 · 注意：基数词变序数词的变化口诀： 基变序，容易记，加上th就可以； 一二三，特殊记，词尾字母tdd;first,second,third 八去t，九去e,f来把ve替；eight→eighth,nine→ ninth ,five→ fifth,twelve→ twelfth 若是遇到整十数，ty变作tie;twenty→ twentieth，thirty→ thirtieth 若是遇到几十几，只变个位就可以。twenty-one →twenty-first · 注意：表示顺序时，前面必须加定冠词 the , 如 the first day(第一天)、 the third floor (三楼) 。 【大显身手】 一、写出对应的基数词/序数词 1. 3 → ______ 2. 第二 → ______ 3. 10 → ______ 4. 第十二 → ______ 二、选词填空（基数词/序数词） 1. There are ______ (five / fifth) birds in the tree. 2. She is the ______ (two / second) student in the line. 3.Our classroom is on the__________(three/third)floor. 4.Thursday is __________(five/fifth)day of the week. 考点三：help的常用搭配 解析：help动词或名词都表示“帮助”,形容词 helpful“乐于助人的” 短语搭配： 一、help sb. (to)do sth. (to 可省略)帮助某人做某事。 例：Can you help him(to)carry the box? 你能帮他搬箱子吗? 二、 help sb.with sth. (sth.为名词/代词)在某件事上帮助某人。 例：Miss Li helps me with my English.他帮我学英语。 【大显身手】 一、用所给词的适当形式填空。 1.Let's_______(help)the old man________(carry)the heavy bag. 2.A__________(help)student always__________(help)his classmates. 3.My mother _______(help)me_______(介词)my homework. 4._______（can）you________(help)me? 考点四：字母 “i”的发音 /ɪ/ 解析：字母“i”目前有2种最常见的发音，本单元是音标：/ɪ/,读音：短、轻、快，像短促的“衣”，嘴巴小小的，不要拉长,口型：嘴微张，舌尖抵下齿，声音短而有力,字母 i 在短单词、闭音节里，后面没有不发音的 e，一般就读 /ɪ/，例如： big, pig, fish, six · 拓展：区分口诀：i 遇尾e，读 /aɪ/；无尾e，读 /ɪ/；长音响亮“爱”，短音轻轻“衣” 【大显身手】 一、选出画线部分发音不同的一项。 ( )1.The ice cream is nice and big. A B C ( )2.His sister likes riding a bike. A B C ( ) 3.The pig sits on the white chair. A B C ( )4.This little girl can ride a horse.
