亲？)
3、which除了可以询问指代的情况之外,还可以针对说明人物的
时间、地点、岁数、颜色、大小、状况等进行提问。如：People there live a very sad life.(那里的人生活凄惨) →Which people live a sad life? (哪些人生活凄惨？)/ --Which hotel have you booked for your holiday?(为了度假你预订了哪家旅馆？)—The biggest one in Haikou.(海口最大的那家旅馆) 4、疑问代词不分单复数,视它所替代的人或事物决定单复数,但是
通常用单数；如果修饰名词,则以名词的单复数为准。如：Who is (are) in that playhouse?(谁在游戏房里？) / What is that? (那是什么？)/ What are those? (那些是什么？) / What colours do they have?(它们有哪些颜色？)
四、数词：
1、分类：数词有基数词和序数词两种。英语的数词可以作句子的主语、宾语、表语和定语。
2、基数词：表示数目的词叫基数词。
1、 英语中常用的基数词有：
1 one 2 two 4 e 6 r
20 twenty 40 forty 60 sixty
3 thre13 thirtee30 thirty
14 n 16 en
5 fou15 fourte50 fifty 7 five 17 fifteen 70 seventy 8 six 18 sixtee80 eighty 9 sev1en 0 eig1ht 1 nin1e 2 ten eleven twelve
19 n

90 ninety 0 hundred
sevent10one(a)
23 twenty-three 35 thirty-five
10one hundred 1 and one
1000→one(a) thousand,10000→ ten thousand,100000→one hundred thousand ,1000000→one million,10000000→ten million, 100000000→one hundred million,
108→one hundred and eight, 146→one hundred and forty-six,
500→five hundred , 1001→one thousand and one, 1813→one thousand eight hundred and thirteen.
2、[注]：(1)百位与十位之间要加and；十万位和万位,亿位和千万位之间通常也要加and。
(2)英语用千、百万等单位计数,大数字从右向左看, 每隔三位
划一逗号,倒数第一个逗号之前要用thousand,倒数第二个逗号之前要用million,倒数第三的逗号之前要用billion表示。
(3) hundred、 thousand、 million作数词时,不用复数,前面可
以加上one, two, …等其它数词。用作名词时复数表示“成?上?”,后面必须要有of,前面可以加上some,many,several等词。如：five hundred(五百), hundreds of(成百上千的), ten thousand(一万), thousands of(成千上万的), millions of(成百万的)
3、序数词：表示顺序的数词叫序数词。
1、 英语的序数词基本变法：
(1) 一般在基数词后加th,(2)-ve结尾的改为-fth,(3)-ty结尾的改为-tieth,(4)熟记特殊词。 2、序数词如下：
1st ※

nth enth th nth eenth enth enth

(2) 使用序数词时一般加定冠词the. 如：I‘m in the third grade.
(3) 序数词作“几分之几”讲时,有复数形式。如：1/5→one fifth ;
