不幸的是,您不能在此處使用連續動詞。 Crushing, making在語法上不正確,只有crush, make拼寫crush, make原始動詞crush, make才能出現在這裡。如果你想使用verb- ing在這裡,你來了句改為what we are doing is crushing the fibers and making them weak enough...示例: What we need to do is mix the ingredients together. = What we are doing is mixing the ingredients together. (您將成分混合在一起。)
