我来回答!
I'm more outgoing than my sister是人教版新目标英语八年级上册第六单元的标题句,也是体现了本单元核心语法的句子.
这里的语法讲的是形容词的比较级.
形容词和副词有三个等级：
原级、比较级、最高级
1.原级：即形容词和副词的原形.
small, good, pretty, big, many
hard, happily, slowly, quickly
① 程度副词very,too,so,quite等修饰形容词和副词的原级.
如：very tall、 too hot、 so cold
quite interesting run quickly
② as…as ,(与…一样） not as（so)…as
（与…不一样）中间用原级.
The story is as interesting as that one.
The question is not as / so difficult as that one.
2.比较级：两个人或物之间的比较.表示“较……”或“更……一些”.标志词：than (比）
单音节词通常是-er结尾；多音节或部分双音节词通常在之前加more.
如:smaller, better, taller, older, more, harder
more interesting , more quickly
3.最高级：三个或三个以上的人或物之间 的比较.
标志词：in+大范围, of all, of +the+具体的数字
表示“最……”的意思.（两者以上用最高级）
单音节词通常是-est结尾；多音节或部分双音节词通常在之前加most. 在形容词的最高级前必须加the;副词之前可以不加.如 ：smallest, tallest, newest, best ,most interesting, most difficultly
单音节和少数多音节的形容词和副词的比较级和最高级
的构成分规则和不规则.变化如下
单音节词和少数多音节词
一般在词尾加-er/ə/或-est/ist/
cold colder coldest
fast faster fastest
以字母e结尾的形容词,加-r或-st
nice nicer nicest
large larger largest
重读闭音节词只有一个辅音字母时,应先双写辅音字母；再加-es或-est
big bigger biggest
hot hotter hottest
以“辅音字母+y”结尾的双音节词,先改“+y”结尾的双音节词,先改“y”为“i”,再加-er或-est
easy easier easiest
early earlier earliest
多音节词和部分双音节词,在词前加more或most
tired more tired most tired
easily more easily most easily
常用的不规则变化的形容词的比较级和最高级:
原级------比较级------最高级
good------better------best
many------more------most
much------more------most
bad------worse------worst
far------farther, further------farthest, furthest
比较级的用法： …than…

注意：
1.The new building is higher than the old one.
比较级必须在同类中进行,即人与人比,
物与物比,而且比较结构前后的词语要对称,
特别注意在than或 as 之后不要漏掉可能出现
的替代词 that ,those, one ,ones.
2.His shirt is more expensive than mine.
如果主语是物主代词+名词,那么后面要用名词性物主代词.
3.Kate is more beautiful than Lily is.

当最高级前有物主代词修饰时,其前不加定冠词the.
双音节或多音节形容词和副词的比较级和最高级的特殊情况：
1、一般是在原级前加more构成比较级,在原级前加most构成最高级.

4、有些双音节和单音节形容词,既可以加er或est构成比较级和最高级,也可以加more 和most构成比较级和最高级.
