1、欢欢迎迎来来到到英英语语课课堂堂第三课时第三课时Section A(Grammar Focus3c)单元同步语法精讲 比较级和同级相比形容词、副词的原级即形容词、副词的原形形式，常用于very，so，quite，too之后，适用于句型asas(和一样)。eg：The coat is very expensive.这件外套很贵。The boy is as old as the girl.那个男孩和那个女孩一样大。He runs as fast as I他和我跑得一样快。比较级常用于两者之间进行比较，表示其中一个比另一个“更”或“较”，后用连词than连接另一个所比较的人或物。在上下文明确的情况下

2、，比较级也可单独使用。比较级的构成(1)规则变化单音节和部分双音节的形容词、副词一般在词尾加er。eg：wildwildertalltaller以不发音的字母e结尾的只加r。eg：latelaterfinefiner以重读闭音节结尾，末尾只有一个辅音字母，需双写词尾辅音字母，再加er。eg：hothotterbigbigger多音节和部分双音节词，在原级前加more。beautifulmore beautifulcarefulmore careful(2)不规则变化good/wellbetterbad/illworsemany/muchmorelittlelessfarfarther/furt

3、her比较级的用法(1)形容词比较级常用于两者之间的比较，表示两者之间的差异，构成形式多为“主语谓语(连系动词)比较级than比较对象”。eg：They have more orange than we(do)/us.他们的橘汁比我们的多。在上下文意思明确的情况下，也可以单独使用比较级。This coat is too small.Do you have a bigger one?比较级之前加much，far，a bit，a little，even，still，a lot 等词修饰，用于加强语气。eg：She is a little fatter than me.她比我胖一点。(2)asas意

4、为“与一样”，否定形式“not as/soas”意为“不如；不与一样”也是一种表达比较的形式。但as与as之间用形容词、副词的原级。eg：This room is not as/so big as that one.这个房间不如那个房间大。This room is smaller than that one.单元同步语法强化训练一、单项选择。1Do you enjoy Han Leis songs？(2014，南京)Yes.He is the winner of Im a singer.I cant think of anyone with a_voice.AbetterBbestCmoreD
