Each virus strain is grown separately inside the eggs over the course of several days,
which
it is harvested, inactivated, and purified.
选项
A、from which
B、by which
C、after which
D、before which
答案
C
解析
(1)画线部分错误分析。
本题考查关系从句,介词+关系代词的用法。在本句中,which指代时间词days,因此其前面的词只能使用before,during和after;结合上下文可知,“采集、灭活和提纯”只能是“在卵内生长”之后发生的事情,因此画线部分应为after which。
(2)选项分析。
综上所述,关系代词which指代several days,根据句意,介词搭配为after several days,定语从句还原为:It is harvested,inactivated,and purified after several days,因此,只能使用after表示之后,所以选项C为正确答案。
