二、用法联想

1. five-year-old中的year可用复数吗?

不可以。five-year-old这类结构中的year只能用单数，不能用复数。如：

误：Her two-years-old son toddled into the room.

正：Her two-year-old son toddled into the room.

2. five-year-old中的连字符可以去掉吗?

不可以。若去掉，则要转换表达方式。如：

3. five-year-old可用作表语吗？

正：She was twenty years old, but married a man of fifty.

4. five-year-old前用a还是an？

five-year-old前若需要用不定冠词，要用a，不能用an。但是，若将其中的five改为eight, eleven, eighteen, eighty等，则其前要用an，不用a——尤其是当它们以8, 11, 18, 80这样的数字出现时更要引起注意。如：
