分析一致性，巧妙学数词数词属限定词，它与很多词存在一致关系，分析这些一致关系，可以巧妙地学习数词。 一、 分析数词与名词一致性，巧妙学习数词基数词（大于 1）后面应接复数名词，但复合形容词中的基数词应修饰单数名词，序数词后面应接单数名词。表示第几时可用 the+序数词+单数名词，也可用单数名词加基数词。 例 1：She has one pink pen and two grey ________. A. one B. once C. one's D. ones 析：D 为正确答案。two 后面应接复数名词。 例 2：We are going to learn ________ next week. A. Lesson Twelve B. Lesson Twelfth C. Twelfth Lesson D. the Lesson Twelfth 析：A 为正确答案。第十二课可表达为 Lesson Twelve 或 the twelfth lesson。 例 3：It's ________ walk from here to my school. A. two-hours B. two hours C. two-hour D. a two-hour 析：D 为正确答案。该空为复合形容词作定语，中间的名词应用单数。 二、 分析数词与量词一致性，巧妙学习数词 数词后面接量词时，数词无论有多大，量词都要用单数形式。 例 1：Two ________ died of cold last winter.
