六年级英语下册知识点梳理Unit 1 How tall are you?一、 单元内容简析：本单元内容的中心话题是询问人或事物的年龄、身高、重量以及长度并作比较。内容涉及恐龙、猴子以及鲸类的比较，学生之间在年龄、身高和体重方面的比较。二、单元词、句、语法等方面的知识重点：知识词汇四会单词taller,shorter,stronge,older,younger,bigger,funnier,heavier,longer,thinner,smaller （重点）三会单词little,tail,think,size,wear,yours二会单词cm(centimeter),than,funnier,kg(kilogram),feet,meter,ton,each,squid,lobster,shark,deep,seal,even短语sperm whale,killer whale,up to,dive into,good swimmer,the length of,line up,from to语法词法形容词比较级的变化规则：1、直接在形容词后加“er”,例如long-longer, tall-taller。2、以字母“e”结尾的直接加“r”，例如nice-nicer。3、重读闭音节只有一个辅音字母结尾的，双写最后一个辅音字母后再加“er”,例如thin-thinner,big-bigger。4、辅音字母加“y”结尾的先把“y”改为“i”再加“er”，例如funny-funnier,heavy-heavier。5、部分双音节或多音节加“more”，例如careful-more careful。6、不规则变化，例如good-better。句子句 型1、How 形容词be主语？2、A比较级thanB.3、主语be数字单位tall/heavy/long四 会How tall are you?Im 164cm tall. You are shorter than me. You are 4cm taller than me. How heavy are you?Im 48kg. Im thinner than you,and shorter.（重点）三、 本单元难点：1、数字的读法，含有“厘米、千克”单位的读法。如百以上164：one hundred and sixty-four,学生可能读的时候百后不知加“and”，还有千的读法：thousand,小数的读法等。2、形容词比较级的用法与变化形式，哪些要双写，哪些要把y变i成再加er,到底在什么情况下变比较级要加上more。3、代词的用法，特别是名词性物主代词的用法。四、易考点与易错点：1、词语类：四会词语在听力部分听写或笔试部分按照汉意写词语。按要求写词语：变比较级funny,heavy,big,thin；long的名词，foot,tooth复数，heavy(heavier)的反义词light(er)very修饰原级，much修饰比较级。例如：He is very tall. He is much taller than you.2、语法、句型类：How引导的不同特殊疑问句:How be sb.?（问某人状况），How tall/heavy/old be sb./sth?（询问身高、体重、年龄）How long/big/large be-?（问多长、多大）How many/much（问数量、价格）。比较级的运用，一定要是相同内容或类别才可以进行比较，这是学生最易出错和混淆娥地方。例如：Mikes legs are longer than (John)，如果学生翻译会直接填写John，但是一分析就不难发现应该和John的腿作比较的，所以应该是Johns。再比如My hair is longer than (she).如果不仔细分析大多数学生都会错填成：she,her,但是填hers才是正确的。Unit 2 Whats the matter,Mike?一、 单元内容简析：本单元的教学内容主要是围绕“看病就医”和“描述心情”两个话题展开。二、单元词、句、语法等方面的知识重点：词汇四会单词hurt,matter,sore,nose,tired,excited,angry,happy,bored,sad（重点）短语have a fever,have a cold,have a headache,have a sore throat（重点）三会单词people,know,pass,guess,game二会单词feel,sick,flu,might,worry,medicine,drink,stay,better,soon,trip,fail,test,hear,match,between,kick,goal,another,win(过去式won)短语a little,laugh at,feel sick,broken leg,have/get the flu,dont worry,see a doctor,take some medicine,drink hot drinks,stay in bed for a few days,feel better,look so happy,go on a big trip,fail the math test, at the end ofa footballmatch,between-and-,pass-to-,kick the ball,fly into,bounce off句子时态一般现在时：(注意主语是第三人称单数的句子)句式How助动词主语动词原形? 主语have/has疾病类单词四会Whats the matter with you?/Whats wrong with you? My nose is sore. My nose hurts. How are you? You look so happy. You look sad today.(重点)三、难点是学生能在各种语言环境中正确熟练地运用不同句型进行交流。四、易考点与易错点：1、词语：四会词语和短语会出现于听力部分的补全句子或按汉语意思翻译。了解“疼痛”的区别：hurt是动词指“使受伤”,ache是名词后缀,加上身体某部位常指某部位疼痛，sore是形容词可以放在表示身体某部位的词语前作定语或放在be动词后做表语。hurt和sore有时可以替换。armache,stomachache I hurt my nose. My nose hurts.My nose is sore.注意people是集合名词,单数和复数同形；medicine是不可数名词，没有复数形式。短语“为某人买某物”，buy sb. sth./buy sth. for sb.当某人放在前面时不用加for，否则要加介词for. buy me a ball, buy a ball for me be going to后跟动词,be going on后跟名词，表示将要或打算做什么事情。2、句型：Whats wrong with you? 和Whats the matter with you?意思和用法相同，matter名词要加，而wrong是形容词，常在选择和改错题中出现。注意当主语是第三人称单数的时候，如果没有be动词，谓语动词要加s或es,否定句和疑问句要用does。Mike has (have) a headache. How does (do) your father feel? He doesnt (not) feel well.Unit 3 Last Weekend一、 单元简析：本单元主要是学习和运用一般过去时来表达在过去的时间内所做的事情。二、单元词、句、语法等方面的知识重点：知识点词汇四会单词watch-watched,wash-washed,clean-cleaned,play-playedvisit-visited,do-did,go-went,read-read,last,weekend,park（重点）短语go swimming,go fishing,go hiking （重点）三会单词cook-cooked,study-studied二会单词yesterday,return,fly-flew,swim-swam短语tongue twister句子时态一般过去时句式或句型1、 主语动词过去式过去时间.2、 Whatdid主语do过去时间？3、 Did主语动词原形过去时间？四会句子What did you do last weekend?
