可是the more established industries 用法没错吧 前头有冠词啊,以下这句话是 一本business书上的原话 ‘’However, knowledgeable entrepreneurs choose areas with which whey are familiar, and these are most often the more established industries.‘’
觉得B里头 1. industries that are more established 很wordy啊 2. Although的意思是 in spite of the fact that; even though,表转折 而这里是对比,用whereas (in contrast or comparison with the fact that ) 更好啊 3. as competing companies one day may be partners the next 这个太模糊啊,是 [competing companies one day] may be [partners the next ] 还是 [competing companies] one day may be [partners the next ]
