参考答案：
1-5 DDCAD
6-10 CDBCA
解析：
1. D。“一年半”英语表达为a year and a half或one and a half years。
2. D。hundred, thousand, million, dozen, score的复数形式常后接of短语，scores of意为“很多”。
3. C。当基数词与序数词连用时，一般将序数词放在基数词前面。句意为“能坐在这里吗?”“对不起，前3排座位是留给嘉宾的”。
4. A。表示时间或空间的间隔，可用every+ 基数词+ 复数名词或every+ 序数词+单数名词。每两周可表达为：every two weeks或every second week或every other week。
5. D。当ride, walk, drive等用作名词时，可用来表示一段距离。a thirty-minute walk三十分钟的步行。
6. C。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”，分母用复数。句意：我们班有50名学生，三分之二的人去过长城。
7. D。用在基数词后面的hundred, thousand, million, billion 通常不带复数词尾-s，但如果表示数百、数千、数百万这样的泛指，则用复数，如：hundreds of, thousands of, millions of。
8. B。“another+基数词+名词复数”结构中，another表示“再、又，还”，相当于“基数词+more+名词复数”。句意：——我们至少己经等她四十五分钟啦。——我们再多停留十分钟吧。
9. C。在“整十”的复数基数词前加the，表示在几十年代；在“整十”的复数基数词前加one’s，表示在某人几十多岁时。句意：我兄弟生于80年代，那时我爷爷80多岁。
10. A。dozen意为“一打，十二个”；当dozen与数词连用，而且后面有these, those, them, us等词时, dozen后面应加of，如：a dozen of these people, two dozen of them。表示“许多”时用dozens of。
