问题探究一.形容词和副词比较级的构成

1一般情况在词尾直接加er；以字母e结尾的只加r；

2重读闭音节词尾只有一个辅音字母时，先双写该辅音字母，再加er；

3以辅音字母+y结尾的先变y为i再加er；

4在多音节和部分双音节词的前加more（更多）或less（较少）；

5此外还有一些不规则变化的单词，需要我们特殊背诵P114小结训练写出下列单词的比较级。highlatetallhungrythirstyfuunybighotwetlittlegood/weelbeautifulinterestinghigherlatertallerhungrierthirstierfunnierbiggerhotterwetterlessbettermorebeautifulmoreinteresting用所给词的适当形式填空。Myfatherhas________(short)hairthanmymother.Mymotherhas________(long)hairthanmyfather.Butmyfatheris__________(heavy)thanmymotherand_______________(outgoing)thanher.shorterlongerheaviermoreoutgoing2比较级的用法用法一当两种物体之间相互比较时，我们要用形容词或副词的比较级，“A+be+形容词比较级+than+B”意为“A比B更......

注意：A+be+倍数+比较级+than+Beg.Thisriveristhreetimeslongerthanthatone

用法二much.alot.even.与比较级连用译为…得多eg.Tomismuchbetterthanbefore.

用法三比较级+and+比较级越来越…egItishotterandhotter

用法四the+比较级，the+比较级越…就越…egTheearlier,thebetter.Theharderyoustudy,thebettergradeyouwillget.3.as...as的用法1）我和内莉一样高。IamastallasNelly.2）汤姆和萨姆跑的一样快。TomrunsasfastasSam.3）莉莉不如露茜外向。LilyislessoutgoingthanLucy.as...as的含义为“和......一样”，用于形容词、副词的同级比较。两个as的词性和用法不一样，第一个as是副词，后面接形容词或副词的原级，第二个as多为连词。as...as的否定形式为notas/so+adj./adv.+as，表示“不如......”，其中，第一个as可以用副词so替换，但第二个as则不能。

思考：ThisriverisaslongasthatoneYouwillgetgoodgradesaslongasyoustudyhard问题探究

make的用法1）我无法使这匹马走动。Ican'tmakethehorsewalk.2）他常常使我感到快乐。Heoftenmakesmehappy.

make“使，促使”，在此是使役动词。当它作“使，让”讲时，常见结构是：1）make+人（宾语）+动词原形（宾补）；2）make+宾语+形容词（宾补）。
