Why not try your luck downtown,Bob?That's ______ the best jo

引导表语从句时连接副词where,when,why,how除在句中起连接作用外,在从句中还充当时间、地点、方式、原因状语,本身具有词义.•x09That’s where I can’t agree with you.
•x09This is why Sara was late for the meeting.
•x09 This is how they overcome the difficulties.
•x09 My strongest memory is when I attended an American wedding.

这个从语义上考虑就是选A啊，那里是很多好工作所在的地方

be动词后面跟表语，一般表语从句经常由that引导并且不能省略。而这个句子中要用where代替luck downtown 在从句中做地点状语，此时用疑问副词作表语从句的引导词
