英语问题-单项选择2727.There are 40 programs in the 2013Spring Festiv

in which是介词加关系代词,引导定语从句,可以翻译成在„„里面
of which 意为其中
定语从句的主语是few,little,some,most,many,much等时,一般只用of whom和of which
定语从句的主语是数词、形容词的最高级时,一般只用of whom和of which
定语从句的主语是all,none,both,neither,each等不定代词时,一般只用of whom和of which
这是我觉得最简单的解释了,我也是读初中滴,应该能看懂吧~

介词要搭配program 你好好理解

不一定对啊，in which指where,意思不对，of which是介词加which,翻译为其中

of which
