32. ___ several times, but he still doesn't know how to use the cleaner.
a.Having been shown b.I have shown him 为什么用B不用A 请详细分析!
a.Having been shown b.I have shown him 为什么用B不用A 请详细分析!
but 连接两个句子,所以前面的句子也应该有主语,所以选B而不是A。如果去了BUT就应该用A了。
Having been shown是现在分词短语的完成式、被动式,做时间状语。相当于一个缩写的时间状语从句After I have been shown several times.
but 像扁担两边要相等。
我认为show是瞬时性动词(即一开始就结束了),不能用been
