语法拓展
一、when引导的特殊疑问句
1.when为疑问副词,常用来询问时间,意为“什么时候”。When is sb.'s birthday?是用来询问某人生日是何时的常用句型,意为“……的生日是什么时候?”其答语为:Sb.'s birthday/It's+日期,这里sb.'s要用形容词性物主代词或名词所有格。
—When is her birthday?
—Her birthday is on August 9th.
2.名词所有格表示“某人的”,通常是 “名词+'s”。
二、序数词
1.概念:表示事物的顺序的数词叫做序数词,它的作用相当于名词或形容词。
2.构成:
(1)变异类:one→first第一;two→second第二;three→third第三。
(2)普通类:第四至第十九均在相应的基数词后加-th,但第五(fifth)和第十二(twelfth)均把基数词five和twelve词尾的ve改为f,再加-th。基数词eight的序数词,直接在后加-h,即eighth。基数词nine的序数词,将词尾的e去掉,再加-th,即ninth。
(3)“ty类”:即以“ty”结尾的整十的序数词是把对应基数词的最后一个字母y变成i,再加-eth。如:twenty→twentieth;forty→fortieth
(4)几十几类:表示“几十几”的基数词变序数词时,只将个位变成
序数词,十位数不变。如:twenty-three→twenty-third
【注意】序数词的前面往往加定冠词the,但当序数词前有物主代词、指示
代词等修饰时,则不必加the。
三、时间介词on,in与at辨析
1. on常用在表示星期几或具体某一日及某一日的上午、下午或晚上的名词前。如:on May 4th在五月四日
2. in常用在年、月、季节、世纪及表示泛指上午、下午或晚上的名词前。
in March在三月。如:in the morning在早上
3. at常用在表示某一具体时刻的名词前。
如:at ten在十点;at noon在正午
