1、可数名词如何变“复数形式”:

a.一般情况下,直接加-s,如:book-books, bag-bags, cat-cats, bed-beds ;读音:清辅音后读[s],浊辅音和 元音后读[z]。

b.以s. x. sh. ch结尾,加-es,如:bus-buses, box-boxes, brush-brushes, watch-watches ;读音:[iz]。 c.以“辅音字母+y”结尾,变y为i, 再加-es,如:family-families, strawberry-strawberries ;读音:[z]。 d.以“f或fe”结尾,变f或fe为v, 再加-es,如:knife-knives ,thief-thieves;读音:[z]。 e.以“o”结尾的词,分两种情况

1)有生命的+es 读音:[z]如:mango-mangoes tomato-tomatoes hero-heroes 2) 无生命的+s 读音:[z]如:photo-photos radio-radios

f. 不规则名词复数: man-men, woman-women, policeman-policemen, policewoman-policewomen,

snowman-snowmen, mouse-mice, child-children, foot-feet, tooth-teeth, fish-fish,

people-people, Chinese-Chinese, Japanese-Japanese 1、写出下列各词的复数。

人称 代词 物主 代词 主格 宾格 形容词性 名词性 I me my mine you you your yours 单数 he him his his she her her hers it it its its we 复数 you you your yours they them their theirs us our ours I(宾格)_______ she(形容词性物主代词)_______ we(名词性物主代词)_______ he(复数)_______ us(单数)_______ theirs(主格)_______ its(宾格)_______ 2、想一想,把下表补充完整。 人称代词 第一人称 第二人称 第三人称

2、形容词、副词比较级的规则变化如下:

(1)一般直接+er。如:tall - taller, fast - faster 单音节词如果以-e结尾,只加-r。如:late - later

(2)重读闭音节词如末尾只有一个辅音字母,须双写这个字母,再加-er。如:big - bigger, fat - fatter (3)以辅音字母加-y结尾的词,变y为i,再加-er。如:heavy - heavier, early - earlier (4)双音节和多音节词的比较级应在原级前加more构成。如:beautiful - more beautiful, careful - more careful, quietly - more quietly, interesting - more interesting

(5)有些不规则变化的,须逐一加以记忆。如:good/well – better, bad/ill – worse, many/much – more, far – farther/further, old – older/elder…
