17、35分钟得到的；钟点数nine是由8加上1得到的）。注意： 当分钟数是15分钟时，可用名词quarter （一刻钟）表示。例如：【牛刀小试】7:15可表示为 a quarter past seven， 12:15可表示为 a quarter past twelve 当分钟数是30分钟时，可用名词half （一半）表示。【牛刀小试】9:30 可表示为 half past nine，3:30可表示为 half past three。III. 数量词的用法。表示长、宽、高，用“基数词+单位词（meter, kilometer, foot, inch等）+形容词（long, wide, high等）”
