cn | 译文: (/采用cDNA探子/来探测p荷尔蒙)这样一种分子生物学 手段 也应该 /比免疫学方法要快得多/,/因为后者 要花上 几年的时间做枯燥的提纯工作 ,/来分离p荷尔蒙并培养出其抗血清//。 |
explain | 解释: 主语后的修饰成分同样隔开了主语和谓语。但本句的难度主要在because从句中。按照一般的习惯,作为从句主语的it应该指主句的主语,但本句的主句是一个比较结构,A should be faster than B because it...,此处it也可以指B。但是因为这种指代不符和我们以前所形成的习惯,所以阅读现场不得不边读边根据句意来判断,这就增加了阅读理解的难度。 现场阅读时,类似antiserums的这种专有名词不必理会,仅需从词头anti-推出这是一个反p荷尔蒙的东西即可。 |
