Ex. Pong is a classic game from which (have) descended may current computer pastimes.
它说这里通过flip, may current computer pastimes have descended 得到这里用have 我想问:这里想到用flip的原因 是因为定从用的from which,所以classic game 作from的宾语而非从句的主语,因而发现从句没有主语,继而确定从句是倒装结构的么 谢谢!
介词+关系代词的结构的定语从句很容易采用倒装结构,原因往往是因为从句的主语比较长或结构平衡。给个例句: This is the world out of which grows the hope, for the first time in history, of a society. 这句从句的主语很长,所以用了倒装,用正常的语序来看是: The hope, for the first time in history, of a society grows out of which (the world ).
另外,我要纠正LZ的是,你的那道题里从句不是没有主语,而是让主语和句子结构的平衡,所以它用了倒装,它正常的语序是: Current computer pastimes may have descended from which!
