简爱英文原版第二版的序言里,有一句话是：So far as I know,but not,therefore,to be

我是英语专业的大二学生,虽然还不成熟,但是可以和你交流一下我的观点.therefore在牛津词典中只有一个意思：for that reason.这句话原句是 I turn to another class;a small one,so far as I know,but not,therefore,to be overlooked.此句中so far as I know可以去掉不看,即a small one,but not,therefore,to be overlooked.翻译过来就是是一个小的阶层（团体）,却不应该因此（因为小）而被忘记.所以therefore仍然是因此之意
