| 背面 |     释义： 1、Latin surdus "deaf, unheard, silent, mute". => surd-: deaf, unheard, silent, mute.2、surd- => surd: irrational.3、咱们汉语里有表达这种关联的形象的成语：掩耳盗铃、装聋作哑、充耳不闻；这些行为是不是都非常的荒唐、荒谬、无理取闹啊！因此，由词根含义转变到、引申到单词含义自然就水到渠成了。4、ab- "away, off; 由于该前缀的这层含义，在这里添加在surd之前更加强了surd的含义，为什么呢？想一想充耳不闻、装聋作哑地走开(away, off)，就明白了！" + surd- / surd + -ity => absurdity.5、In surd, the mathematical sense is from the use of Latin surdus to translate Arabic (jadhr) asamm "deaf (root)," itself a loan-translation of Greek alogos, literally "speechless, without reason".6、In French, sourd remains the principal word for "deaf".n. 马力（功率单位） 例句： 1. a powerful car with a 170 horsepower engine发动机为170马力的大功率汽车 horsepower 马力horse,马，power,能量。即马的力量，后来被物理学家用来指能量单位。 horsepower (n.)1806, from horse (n.) + power (n.); established by Watt as the power needed to lift 33,000 pounds one foot in one minute, which is actually about 1.5 times the power of a strong horse." |
