小学六年级英语比较级和最高级的知识讲解
学习重难点：
1.熟练掌握形容词和副词比较级和最高级的构成。学习过程及内容：
比较级：两者间的比较。最高级：三者及其以上比较，选出一个“最”。
一。了解什么是单音节，双音节和多音节。
二。掌握单音节词和部分双音节词比较级和最高级的构成、用法。1.构成。
知识点（1）.一般情况在原级词尾加-er构成比较级，加-est构成最高级。
如： small→smaller→smallest clever→cleverer→cleverest。
例题：short tall cheap narrow
知识点（2）.以e结尾的词，直接加-r 或-st。
如：large→larger→largest nice→nicer→nicest
注意：late→later（较晚的）→latest（最新近的）(时间的先后）late→latter（稍后的）→last（最后的）(顺序上的先后）
例题：nice
able
safe
知识点（3）.以一个辅音字母结尾，其前面的元音字母发短元音的形容词的比较级和最高级，是双写该辅音字母然后再加-er和-est。（注意：这里是字母，不是音标。辅音字母是除 a,e,i,o,u五个元音字母以外的都是辅音字母。）
如：big→bigger→biggest。
例题：hot fat thin 知识点（4）.以“辅音字母 + y”结尾的词，先变 “y”为 “i”，再加-er 或-est。
如：happy→happier→happiest easy→easier→easiest 例题：heavy
busy lucky
知识点(5)不规则变化，常见的有这六个。
good / well→better→best bad / ill→worse→worst
many / much→more→most
little→less→least
far→farther→farthest(表示距离)/ far→further→furthest(表示程度)old→older / elder→oldest(表示新旧或年龄)/ eldest(表示兄弟姐妹之间的长
幼关系）
2.用法。
比较级：a +be(is/am/are)+ 形容/副词比较级 + than + b
如： yao ming is tall than me.i’m short than yao ming.例题：(1)the red box is(heavy)than the blue box.(2)i’m three yeas(older/elder)than him.(3)this man is than that man.最高级： a+the+形容/副词最高级+表示的范围（in比较对象不是同一类，of比较 对象时同类）
如： tom is the tallest student in his yellow river is the scend longest river in chian.例子：(1)apple a is the（big)of the three/ in the box.(2)用heavy,bad的比较级和最高级造句。
(3)which subject do you like ,maths or english? 三。大部分双音节词和多音节词的构成。
大部分的双音节词和多音节词，比较级在前面加more，最高级在前面加most。
注意：（1）形容词最高级前通常必须用定冠词 the，副 词 最 高 级 前 可 不 用。
（2）形容词most前面没有the，就没有最高级的意思，不表示最高级的含义，只表示“非常”，用来加强语气之意。
如：beautiful→more beautiful→most beautiful different→more different→most different easily →more easily →most easily often →more often →most often 例题：exciting helpful important dangerous modern 例子：the book is more is the third largest country in the word.例题：(1)my job is too boring ,i’d like to do something(interesting)(2)it is one of(dangerous)animals in the word.(3)she is(beautiful）student in the class。
