half。（3）百分数的表达方式是：基数词percent。Forty percent of the students in our class are from cities.我们班有40%的学生来自城市。2分数的用法“分数of限定词名词复数”作主语时，谓语动词应用复数形式；“分数of限定词不可数名词/名词单数”作主语时，谓语动词应用单数形式。但“分数of限定词population”作主语时，谓语动词应用复数形式，此时population意为people。One half of the students are from China in this school.这所学校一半学生来自中国。Two thirds of her money is spent on clothes.她把三分之二的钱花在了衣服上。Three fourth of the population in Singapore are Chinese.新加坡四分之三的人是中国人。1（2012湖南郴州中考，34）Last year，one hundred English

专题四数词专题提升演练1A数词与名词之间用连字符连接作定语，其中的名词用单数形式，故选A项。2A分数表达法：分子用基数词，分母用序数词；分母大于1，分母加s。故选A项。3C由具体数词修饰时，thousand用单数形式，故选C项。4Csixteenyearolds在此指十六岁的青少年。5A由题意三名学生跑得比莉莉快，可知莉莉是第四名。故选A项。6B句意：在他五十岁的时候他写了他的第五部小说。故答案为B项。7Aa与序数词连用强调“再一次，再一个”。8A由答语“对不起，我不知道。”可知这是其第一次来这里，故选A项。9A若hundred，thousand与million等词无具体的数词修饰，则用复数形式，且其后加of，表示不确切的数量。10B在原有基础上再增加两天用two more days或another two days表示。11A652的读法是six hundred and fiftytwo，百位前有six，不能加s，百位与十位间加and，十位与个位间加连字符。12A分子大于“一”时，在表示分母的序数词后要加s，land是不可数名词，动词要用is。13C句意：我没有明天演讲比赛穿的白鞋子。我弟弟有一双。你愿意试穿它们吗？one在此表示泛指“一”；shoes是复数，故用them代替作try的宾语，因此选C项。14C分数修饰名词作主语，动词形式与名词一致。water是不可数名词，所以动词用has。15B“七点四十五”表示为a quarter to eight。16Canother“另一个，再一个”，其后跟单数名词；others是代词，不修饰名词students；数词与more连用时放在more的前面，与another连用时放在another的后面。故选C项。17Bthousand，hundred，million等数词，当其前面有具体数目或several类的限定词时，不用复数后面也不跟of，当表示不确切数目时，其后加s且跟of。句意为“重庆政府正在为人民建造成千上万的便宜且优质的住房。”故选B项。18B“学校十五周年庆典”应用序数词表示；in后跟时间段，应该用基数词表示，故选B项。19Cmedal是以辅音音素开头的单词，先排除B项；另
