表示“几百”的时候，使用“基数词+hundred”的结构，hundred后不加s，本题是“两百”，故选A。
点睛：表示确切的数字（具体数字+概数词+复数名词）hundred，thousand，million等词与具体数字（如one，two）连用时，要用单数形式（其后不加s），一般不与of连用。
2．D解析：D【解析】试题分析：句意：什么是“three quarters”的意思是什么，李平？我明白。
它的意思是四分之三。
在表示时间时，“three quarters”指的是三刻钟即45分钟，在表示数目时，“three quarters”指的是四分之三。
在英语中，分数的分子用基数词，分母用序数词，当分子大于一时，分母要用复数形式。
所以选D。
考点：考查数词。
3．A解析：A【解析】试题分析：句意:-这台电脑多少钱？-大约三千元。
thousand 千，它主要有两个用法，一是和数词连用表示具体数量时，不用复数形式；二是构成短语thousands of ，成千上万的。
这里考查的是第一个用法。
故选A。
考点：考查数词。
4．A解析：A【解析】句意：——你妹妹多大了？——21岁，我们昨天为她第二十一个生日开了一个特别的派对。
表示年龄时使用基数词的形式，在多少岁生日前用序数词，故答案为A。
5．B解析：B【解析】句意：－你好，凯特，这栋楼房有二十层，你住在哪一层？－我住在第十二层。
前句表示楼房有二十层，二十，表示数量，用基数词twenty；后句表示住在第十二层，第十二，表示顺序，用序数词twelfth。
故选Ｂ。
