That’ s the tallest dinosaur【1】in this hall.Mike: Yes, it is. How tall is it?【2】Zhang Peng: Maybe【3】4 metres.Mike: Wow! It ‘s taller than both of us together.【4】Zhang Peng: Look! There are more dinosaurs over there !【5】Mike: They ’all so big and tall.Zhang Peng: Hey, this dinosaur isn’t tall! I’ m taller than this one.【6】Mike: Oh, yes. How tall are you?Zhang Peng: I ’m 1.65 metres1、That’ s the tallest dinosaur!那是最高的恐龙Tall(高的)→taller (更高的)→tallest(最高的)原级比较级最高级形容词的比较级一般以er结尾,而形容词的最高级大都以est结尾!此外,形容词最高级前面要有定冠词the!I ’m shorter than you,but Sara is the shortest in the classroom我比你矮,不过萨拉是班上最矮的2、How tall is it ? 它是多高的?这是一个用来询问高度的句型,回答时的结构可以为:主语+ be动词+ 数字+ 长度单位+ 形容词tall—How tall are you?你有多高?—I am 1.67 metres ( tall ) 我一米六七—How tall is your tree?你的树木有多高?—It is 87 centimeters ( tall ) 它有87厘米那么高【拓展】how可以与许多词连用,表示不同的意思How much 多少钱?/ 多少(不可数名词)How much is your bag?How many 多少?(可数名词)How many apples do you have?How big 多大?How big are your feet?How heavy 多重?How heavy are you?How long多长?How long is your hair?How old?多大(年龄)How old are you?/ I’m 12 years oldHow far?多远(距离)How far is your home from school?3、Maybemaybe是一个副词,意为“大概,或许,可能”,常位于句首,修饰后面整个句子,表示不太肯定的猜测。

Maybe you are right 也许你是对的Maybe that is Mike’s uncle 也许那个人是麦克的叔叔Maybe 与may be,二者都是“也许,可能”的意思;不过,maybe是副词,是一个整体,使用时常放在句首;May be 是两个词的构成,may 是情态动词,后接谓语动词原形,所以当句子的谓语是be动词时,受may的影响,am/is/are必须变回原形be,所以may(可能)+ be(是)= 可能是;You may be rightThat may be Mike’s uncle4、It ‘s taller than both of us together 它比我们两个加起来更高①当我们使用形容词比较级,常常是用两样东西来比较,这时,一样东西作主语,另一样东西则需借用than(比)引入比较级的体貌公式:A + be 动词+ 形容词的比较级+ than(比)+ B翻译:A是比B 更加......的I am heavier than you 我是比你更重的Zoom is stronger than Zip Zoom是比Zip更加强壮的She is younger than me 她是比我更加年轻的【拓展】我们可以用much,a little等词来修饰形容词的比较级,表示更...程度的大小强弱An elephant is much bigger than an ant 一只大象比一只蚂蚁大很多I am a little taller than you 我比你高一点点②both of us 我们两个Both of us are students 我们两个都是学生5、There are more dinosaurs over there ! 那边有更多的恐龙①many/much(许多)→more(更多的)原级比较级He drink much milk,but I drink more milk than him他喝了很多牛奶,但我喝得比他更多I have more apples我有更多的苹果②over there在那边get/go there去那边come here来这里6、I’ m taller than this one. 我比这一只更高One是指刚才谈论话题中涉及物体的任意其中一个,在这句话当中,one指代的就是Mike和Zhang Peng谈到的恐龙的其中一个。

One 与it 的区别:One:指代前面提到的某种同类事物中的任意一个;Dogs are lovely,I want to buy one 狗狗们好可爱啊,我想买一只It:it 指代前面提到的某样事物,是特指!There is a dog over there. It is lovely. 那边有一只小狗,它好可爱7、and 和orAnd ,意为“和”,出现在肯定句当中I like apples and oranges 我喜欢苹果和橙子or,在疑问句中是“或者”的意思,出现在否定句中是“和”的意思What fruit do you like,apple or orange?你喜欢什么水果?苹果或者橙子?I don’t like apple or orange 我不喜欢苹果和橙子Part B一、主要单词thinner更瘦的heavier更重的bigger 更大的stronger更强壮的smaller更小的二、课文导入Mike:Those shoes in the window are nice!【1】Let’s have a look.【2】Wu Yifan:What size are your shoes,Mike?Mike:Size 7Wu Yifan:Size 7 ?

I ’m 46 kilograms.1、Those shoes in the window are nice!在窗户里的那些鞋子是很漂亮的!①those(那些)→that (那个)these(这些)→this (这个)This,that,these,those叫做指示代词,它们既可以充当形容词,也可以充当名词;②those shoes in the window 窗户里的那些鞋子介词短语介词短语通过后置的方式来修饰前面的名词,在这里,介词短语= 形容词,形容词+ 名词= 名词! 所以尽管those shoes in the window 看起来很长,归根到底只说了一样东西,shoes,shoes 是整个句子的主语!Shoes are nice!I want to read a book about space travelShe has a house with a beautiful garden2、let ’s have a look!让我们看一看!①Let ’s = let us 让我们Let sb do sth 让某人做某事Let ’s play football 让我们来踢足球!Let me sing a birthday song for you 让我为你唱一首英文歌!②have a look 看一看英语里还有许多类似的表达:Have a try 试一试have a rest 休息一下have a walk 散散步3、I wear size 38 shoes. 我穿38码的鞋子①提问:What size are your shoes?你的鞋子是什么码数的?I wear size 38 我穿38码的What color is it?它是什么颜色?What time is it now?现在是什么时间?②wear,动词,意为“穿(衣服);戴(眼镜);留(长发))”等She is wearing a red skirt today 她今天穿着一件红色的短裙We need to wear sunglasses when we play on the beach 在海滩玩耍的时候需要戴眼镜My sister wears long hair 我姐姐留着一头长发4、Your feet is bigger than mine. 你的脚比我的脚要大①foot (复数)feet 脚goose (复数)geese②mine,名词性物主代词,是名词,意为“我的东西”,这样东西指代前面谈话中刚出现过,在your feet is bigger than mine中,mine = my feet ,我的东西指的是我的脚My hair is longer than yours 我的头发比你的头发长Her eyes are much bigger than ours 她的眼睛比我们的眼睛大很多5、You look taller than me. 你看起来比我更高Look跟六年级上册unit 6学习过的feel一样,是连系动词,连系动词兼有be动词和实义动词的双重性质,一方面它后面跟的是形容词(和be动词一样)作表语,另一方面它作谓语的句子改为疑问句和改为否定句时改法和2类句子一样。
