037. Most novelists and historians writing in the early to mid-twentieth century who considered women in the West, when they considered women at all, fell under Turner's spell.
划线部分的 when they considered women at all, 解释说是,暗示主语这些人很少考虑到了妇女,不明白为什么这么说,百度看了一下说,at all是在否定句中表示“究竟,根本”的意思,但是这个句子中也没有表示否定的词或者语气?
