(2014 全国 I 卷 ·49) While there are amazing stories of instant transformation, for most of us the _________(change) are gradual and require a lot of effort and work, like cleaning up a polluted river. 作主语要用名词,或者说冠词后应当用名词, change 除作动词外也可作名词,所以词性不必变化;由紧接着的 are 可知,要用复数形式。 changes 思路点拨 我们知道,名词在句中的典型用法就是作主语或宾语 ( 位于及物动词或介词后 ) 。如果括号中所给词是名词,又是在句中作主语或宾语时,就无需作词类转换,应考虑是否需要用复数形式。 考点归纳 关于名词,从近四年的高考题来看,在语法填空中只考查了名词的复数形式,但我们认为,名词的所有格也是可能要考的。 1. 名词的复数形式 英语中的名词,只要大于一,就要用复数形式,如“一个半小时”要说 one and a half hours (=an hour and a half) 。可数名词由单数变复数一般是在词尾加 s ,但还有以下几点需要牢记: (1) 以 -s, -x, -sh, -ch 结尾的,加 es 。如: bus—buses, fox—foxes, brush—brushes, approach—approaches 等。例外: stomach—stomachs( 胃 ) 。 (2) 以“辅音字母 +y” 结尾的,变 y 为 i ,再加 es 。如: story—stories, baby—babies, activity—activities, agency—agencies 等。 (3) 以 -f(e) 结尾的常用词,变 f(e) 为 v ,再加 es 。 half—halves, life—lives, thief—thieves, knife—knives , self—selves, leaf—leaves, loaf—loaves, wolf—wolves 等。但个别特殊词一般直接加 s 。如: chief—chiefs, roof—roofs, belief—beliefs, safe—safes (保险柜)等。 (4) 以 -o 结尾的有生命的名词,加 -es 。如: hero—heroes, potato—potatoes, tomato—tomatoes 等。此外,一般直接加 s 。如: radio—radios, zoo—zoos, photo—photos, piano—pianos 等。 (5) 不规则变化的有: man—men, woman—women, foot—feet, tooth—teeth, goose—geese, mouse—mice, child—children, ox—oxen 等。 (6) 单复数同形的有: deer, fish, sheep, aircraft, spacecraft, means 等。 2. 名词的所有格 名词所有格表示所有关系,即“某某的”,主要有以下几种情况: (1) 不以 s 结尾的名词 ( 单数或复数 ) ,加’ s 。如: Jack’s e-mail 杰克的电子邮件, children’s books 儿童图书。 (2) 以 s 结尾的复数名词,加’。如: the girls’ dormitory 女生宿舍 , the teachers’ reading-room 教师阅览室。 (3) 以 s 结尾的单数名词,加’ s 或’。如: our boss’s (boss’) car 我们老板的小汽车, Engels’s (Engels’) works 恩格斯的著作。 名词 +of+ 名词 + ‘s : this watch of my father’s 我父亲的这块手表 名词 +of+ 名词性物主代词: some students of mine 我的一些学生 (4) 双重所有格 考点练透 1. I broke the chocolate into _______(half) and here’s your half. 句中 break /cut sth. into halves 意思是“把某物分成两半”。 halves 2.
