(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？)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：123456789101112onetwothreefourfivesixseveneightnineteneleventwelve13141516171819thirteenfourteenfifteensixteenseventeeneighteennineteen2030405060708090100twentythirtyfortyfiftysixtyseventyeightyninetyone(a) hundred2335101twenty-threethirty-fiveone hundred and one1000one(a) thousand,10000 ten thousand,100000one hundred thousand ,1000000one million,10000000ten million, 100000000one hundred million,108one hundred and eight, 146one hundred and forty-six, 500five hundred , 1001one thousand and one, 1813one 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
