[答案与解析]
1. C。本题考查分数表达法。英语分数词由基数词和序数词组成。分子基数词，分母序数词，分子大于“1”，分母加“s”。句意为“那家工厂三分之二的工人是年轻人。”
2. A。英语中如hundred, thousand, million, billion等基数词修饰名词时，若前面用了基数词，不论后面有没有of,都必须用单数形式。但若前面没有确切的数字而后面有of时，则一定要用复数形式，表示数量之多。句意为“关于美国的年青人已经有人写过许多书了。”
3. A。当hundred前有 具体数字修饰时，用单数形式;复合形容词中的名词要用单数形式。故答案为A。句意为“老师说我们今天的作业是写一篇六百字的作文。”
4.A。“一年半”的表达法有两种: one and a half years和one year and a half句意为“我姐姐来这里之前在那家公司工作了一年半。”
5.D。 “一两分钟”表达法有两种: one or two minutes或a minute ortwo。 句意为“这件衣服几分钟就可做好了，我已经在收尾了。”
