①先行词是thse，指人，关系代词用wh；
The WHO cmmends the way (that/in which) Chinese gvernment fights against the epidemic.
②“whse +名词中心词”这一结构在定语从句中既能作主语，又能作宾语。
关于whse(……的)
①关系词whse实际上是先行词的所有格(…的)；
③Whse… 人=the …f whm/f whm the… 物= the …f which/f which the…

Vluntary dnatins are flded int Wuhan whse peple are suffering mst. Vluntary dnatins are flded int Wuhan the peple f which are suffering mst.
①关系副词在意义上都相当于介词 + which结构： when = n (in, at, during…) + which; where = in (at, n…) + which; why = fr which.
关系代词和关系副词的用法比较
②使用关系代词还是关系副词，一定要注意分析从句的结构。如果缺少主语或宾语，用关系代词；如果缺少时间状语、地点状语、原因状语，则分别用when, where, why。
I’ll never frget the days when we’re faced with the crnavirus. I’ll never frget the days which/that we spent tgether at hme.
