参考答案：
1．A
考查数词。five五，基数词；fifth第五，序数词，根据前面的“The boy is only”可知，这个男孩只有五岁，“五岁”是说男孩的年龄，用基数词，排除B，由第二个空前面的“his”和后面的“birthday”可知，今天是他第五个生日，用序数词表顺序，排除C，故选A。
2．D
考查分数的表达法。分数的表达为基数词作分子，序数词作分母。当分子大于1时，分母上要加-s，而谓语动词的单复数取决于分数之后的名词，不能用likes。结合句意，故选D。
3．C
考查数词的用法。twelve“十二”，是基数词；twelfth“第十二”，是序数词。根据“There are...months in a year and December is...month.”可知第一空用基数词表示十二个月。第二空用序数词表示第十二个月，序数词前通常要用定冠词the修饰，故选C。
4．C
定冠词the修饰序数词，six和seven都是基数词，可排除。seventh第七，sixth第六；根据July（七月）可知选C。
5．C
考查数词。nine九，基数词；ninth第九，序数词。第一个空表示年龄，用基数词；第二个空，用序数词表顺序。故选C。
6．C
考查分数和主谓一致。英语中分数的表达，分子用基数词，分母用序数词，分子大于一时，分母加s，故“五分之二”应表达为two fifths，排除A和B；分数+of+名词在句中作主语，谓语动词的单复数与名词形式一致，“land”为单数，故选C。
7．A
结合句意和语境可知填70的序数词seventieth，名词所有格和物主代词不能与冠词连用，故选A。
8．C
考查数词的用法。根据“the...century”可知此处应该用序数词，“第二十一”应该表示为 the twenty-first，故选C。
9．B
在英语中的分数，分子用基数词，分母用序数词，当分子大于一时，分母用复数形式。have构成现在完成时的助动词，适用于第三人称单数以外的所有人称；has仅仅适用于第三人称单数。本句主语中心词students是复数，所以选B。
10．A
根据选项可知，第一个空所缺的词为分数；分数的表达法为分子基数词，分母序数词，分子大于1，分母加s，所以五分之二的表达方法为two fifths，排除B,D；分数后面的名词为land，又知land意为“陆地，土地”，为不可数名词，根据主谓一致的原则，所以第二个空缺处应用is，故答案选A。
11．D
考查分数的表达。在英语中，分数的表达方法是：分子用基数词，分母用序数词，当分子大于一时，分母用复数形式；根据本规则，结合选项，可知只有D选项two thirds“三分之二”表达正确，故答案选D。
12．C
此题考查分数的表达方式。分数在英语中通常是借助于基数词和序数词来共同表达的。其中基数词表示分子，序数词表示分母。分子超过1，分母要加s，题目分子为three故分母用fourths；分数修饰名词时，若该名词是不可数名词只能用单数；若是可数名词，用单数或复数均可。但是，若它们在句子中作主语，则谓语动词是用单数还是复数取决于名词，即与分数所修饰的名词保持一致。此题中分数后的名词是materials，所以使用are。故选C。
13．A
考查序数词辨析及常识。A. first第一；B. second第二；C. third第三。根据常识可知星期日是一周的第一天。故选A。
14．B
考查分数的表达及主谓一致。在英语中表示分数，分子要用基数词，分母用序数词，当分子大于一时，分母用复数形式。五分之三应该是three fifths；另外，分数+名词复数作主语的时候，后面的谓语动词应该用复数。故选B。
15．C
考查介词短语和分数。1. the number of：…的数量，做主语，谓语动词使用单数；a number of：许多，大量的，修饰可数名词复数，它和可数名词做主语时，谓语动词使用复数；本句谓语动词like是复数，可知填a number of。2.分数表达法：基数词做分子，序数词做分母，当分子大于一，分母用复数，“五分之四”是four-fifths，故第二个空填four-fifths；故选C。
16．D
第一空处根据空后floors，复数可知，用基数词five，排除A和B；第二空处根据空前the以及空后floor可知，译为“第三层”，用序数词，故选D。
17．C
上周末我们为他四十岁生日开了一个特别的派对。年龄的表达应该是基数词，但当表示某人多大生日的时候应该是序数词。故选C。
18．D
考查数词。根据“classes”可知基数词后用可数名词复数，第一空用five；再由“The ... class”可知第二空用序数词表顺序，用fifth。故选D。
19．A
考查数词。第一个空前有“Year”，是名词，后面用基数词，表示编号，Year Eight“八年级”；第二个空前有定冠词“the”，空后有名词“grade”，这里应用序数词，表示顺序，ninth“第九”，D选项拼写错误。故选A。
20．A
第一个空表示有多少层用基数词，第二个空表示住在第几层楼，用序数词fifteenth，根据题意，故选A。
21．first
此处表示顺序，要用序数词，故填first。
22．twelfth
twelve“十二”，基数词；根据“December is the...month of a year.”可知，此处要填序数词表示顺序，“twelve”的序数词为“twelfth”，表示“第十二”。故填twelfth。
23．twentieth
此处应用序数词twentieth“第二十”作定语修饰century，即二十世纪。故填twentieth。
24．first
根据“Sunday is the … day of a week”可知，此处表示顺序，用序数词表顺序，故填first。
25．thirds
此处表达的是分数，分母要用序数词形式，分子是two，分母要用复数形式，故填thirds。
26．ninth
句中“grade”为单数名词，意为“年级”，应用序数词表示在几年级。基数词nine的序数词为ninth，意为“第九”，故填ninth。
27．twenty-fourth##24th
根据空前的“The”和空后的“Winter Olympic Games”可知，应该是第24届冬季奥运会，用twenty-four“二十四”的序数词twenty-fourth“第二十四”表顺序，也可以直接用缩写形式24th，故填twenty-fourth/24th。
28．eighths
此处是分数表达，分数的表达结构是“先分子，后分母，分子基，分母序，分子大于一，分母加s”，空格缺的是分母，用序数词eighth表示，分子大于一，分母变成eighths。故填eighths。
29．ninth
此空格处表示顺序，意思是“一年中的第九个月”，应用序数词，nine“九”，基数词，ninth“第九”，序数词，故填ninth。
30．hundredth
根据“one...birthday”和所给词汇可知，表示第几个生日应用序数词，“hundred”“百”的序数词形式是“hundredth”。故填hundredth。
