為何此處克勞德會說「half a million」,而不是「five hundred thousand」?

通常在口語對話中,不太會提到切確的數字。比方說:half a million(50萬)、half a billion(5億),更不會提到千以下的數字。Million(百萬)算是常見的計算單位,很少會用「five hundred thousand」,其他計量單位也是相同的用法:half a kilogram(半公斤)、half a cup(半杯),在對話時提到「half a cup」會比「two hundred and fifty milliliters」讓人更容易理解。 例:You only need half a cup of water and a cup of pancake mix to make pancakes. (你只需半杯水與一杯煎餅粉就能做煎餅了。) 例:There are half a million people with the condition, but they might know it. (約有50萬人有這樣的狀況,他們也了解此狀況。)
