参考答案

一 、
1.从考题所提供的答案可知应选择序数词，序数词用来表示数目的顺序，September表示9月份，即一年中第九个月，第九应该是ninth，不是ninths。答案为B。
2.数字用连字符“-”连接作复合定语修饰名词时，连字符连接的名词和数词都必须用单数。故答案为C。
3.当thousand修饰名词时，其前没有数词或a时，则要在thousand之后加s和of连用，表示“成千上万的”。故答案为C。
4.表示“数百”、“数千”、“数百万”等不确切数目时，要用hundreds / thousands / millions of结构表示。D中hundreds of times意思是“数百倍”。答案为D。
5.表示分数时，分子用基数词，分母用序数词。分子大于1时，分母要用复数形式。答案为B。
6.数词 + percent（百分比），前面不加冠词，且percent后不加s。答案为B。
