六年级英语第一单元复习讲学稿一、四会单词：talltaller更高的 shortshorter 更矮的strongstronger更强壮的 oldolder 年龄更大的 youngyounger 更年轻的 bigbigger更大的heavyheavier 更重的 longlonger 更长的 thinthinner 更瘦的 smallsmaller （体型）更小的二、四会句型:How tall are you? 你有多高？Im 164 cm tall. 我164 厘米高。Youre shorter than me. 你比我矮。Youre 4 cm taller than me.你比我高4厘米。How heavy are you? 你有多重？Im 48 kg. 我48千克。三、应该掌握的知识点：1、表示两者之间做比较时，句子中的形容词要用比较级形式。形容词变为比较级的变化规则：（1）一般情况下，在形容词的词尾直接加er。如: talltaller shortshorter.(2)以字母e结尾的形容词，在词尾直接加r，如：nicenicer. latelater (3)以重读闭音节结尾，且结尾只有一个辅音字母的词，先双写这个辅音字母，再加er.如：bigbigger thinthinner fatfatter (4)以辅音字母加y结尾的双音节形容词，先变y为i , 再加er。如：easyeasier heavyheavier funnyfunnier.形容词比较级的变化口诀：原级变为比较级，通常er加上去。若是结尾辅元辅，辅音双写要牢记。辅音加y结尾时，把y变i 是必须。原级若以e结尾，直接加r不后悔。2、部分形容词比较级的不规则变化：口诀特殊形式比较级，共有三对二合一 ，坏病两多和两好；little是小不是少， 一分为二有两个 ，一是老来二是远。good / well better best bad / ill / badly worse worst many / much more most old older oldest (年龄大的,与than连用) old elder eldest(“年长的”,只作定语不与than连用) far farther farthest (距离远)far further furthest (除距离外,还指程度上更进一步的)little less least 3、同义句：How tall are you?=Whats your height?How heavy are you?=Whats your weight?4、以How开头的问句（仅限小学阶段）：How are you? 问身体状况。How old? 问年龄How tall? 问身高X| k |B| 1 . c|O |mHow long? 问长度How big? 问大小（指外型、形体的大小）How heavy? 问体重、重量How many? 问多少，物体的数量How much? 问价格5、its 与its： 这两个词发音相同但意义不同。its是 it is的缩写，汉语意思是“它是”,如：its a fat cat. 它是一只肥猫。its是代词，意思是“它的”，如：That is its tail. 那是它的尾巴。6、My schoolbag is bigger than _.A. you B. your C yours这里的正确答案应该是选项C. yours。Yours是名词性物主代词，它在这里所代表的意思是“your schoolbag”. Than后面要跟名词或名词性短语，因此在这里一定要用名词性物主代词。与形容词性物主代词相对应的名词性物主代词还有：my-mine your-yours hishis herhers itits their-theirs习题一、 选择( ) 1.Im 48 kg. Im _ than you.A. taller B. heavy C. heavier( ) 2.
