新八上Unit3 Same or Different语法专项训练 1、 单元语法 形容词和副词的比较级 1、 形容词和副词的比较级的含义 大多数形容词和副词有三个等级:原级、比较级和最高级。其中,比较级表示“更 ”,用于两者(人或事物)之前的比较,用于说明“前者比后者更 ”。than是比较级句型中的标志词。 2、 形容词和副词的比较级的构成 分类 构成 示例 规则变化 一般情况下,直接在词尾加-er smart-smarter 以字母e结尾的词,在词尾加-r fine-finer 重读闭音节词词尾只有一个辅音字母时,先双写该辅音字母,再加-er thin-thinner; hot- hotter 以“辅音字母+-y”结尾的双音节词,先变y为i,再加-er happy-happier; early- earlier 多音节词和部分双音节词,在词前加more serious- more serious 不规则变化 good/ well better; bad/ badly/ ill worse; many/ much more;little less;far farther/ further;old older/ elder 3、 形容词和副词的比较级的用法 (1) 用于“比较级+ than”结构。than后接人称代词时可以接主格或宾格。比较级用于同类人或事物之间的比较。 (2) “The+比较级 , the+比较级 ”,表示“越 就越 ” (3) 比较级可以用much、a little、a lot、even、still、any、a bit、far等修饰,但不可以用very、so、quite、too等修饰。 (4) 在含有or的选择疑问句中,如果是表示两者间的对比选择,前面的形容词或副词要用比较级形式。 (5) 当表示“两个中比较/ 更 的那一个”时,比较级前要加the。 (6) “more+形容词”可以与“less+形容词”及“not so/ as...as...”结构互换,互换时要注意前后比较对象的位置。 (7) 可用比较级表达最高级含义。 (8) 比较级的替代:使用比较级时,若比较对象是由名词表示的,且有后置修饰语时,则than后用that/ those指代比较对象。that一般指物,不指人;those可指物,也可指人。 2、 写出下列形容词的比较级 1、 shy-_ 2、lazy-_ 3、loud-_ 4、outgoing-_ 4、 serious-_ 6、slim-_ 7、little-_ 8、much-_ 9、safe-_ 10、careful-_ 三、单项选择 1.
