Stronger than FM radio signals, these RF waves are still a billionth the intensity of known carcinogenic radiation like X-rays.
本句中 a billionth the intensity 这几个单词连用,比较奇怪,billionth为什么后面直接可以跟名词呢?请教老师了,谢谢老师。
a billionth为分数词,十亿分之一。分数词、倍数词均为前位限定词,因此其正常位置在中位限定词(定冠词)之前。这是其正常位置。倍数词也是如此。例如,这条绳子是那条的四倍。This rope is four times the length of that one. = This rope is four times as long as that one. = This rope is three times longer than that one.
