Farther and further have been used interchangeably by many writers since the Middle English period. According to a rule of relatively recent origin, however,farther should be reserved for physical distance andfurther for advancement along a nonphysical dimension. Thus 74 percent of the Usage Panel prefersfarther in the sentence If you are planning to drive any farther than Ukiah, you`d better carry chains; whereas '4 percent prefersfurther in the sentence We won`t be able to answer these questions until we are further along in our research. In many cases, however, the distinction is not easy to draw.If we may speak metaphorically ofa statement that is far from the truth, for example, the analogous use offarther should be allowed in a sentence such as Nothing could be farther from the truth, though Nothing could be further from the truth is also justifiable.
Farther 和 further 自從英國(guó)中世紀(jì)以來(lái)被許多作家交替使用。 然而，根據(jù)比較近的起源的法則，farther 應(yīng)被用于實(shí)際距離， 而further 用于沿著非實(shí)際范圍的前進(jìn)。 因此用法專題使用小組中74％的成員喜歡將farther 置于句子 如果你計(jì)劃開到比尤凱亞更遠(yuǎn)的地方，你最好帶上鏈子 中； 而'4%的成員則將further 用于句子 在調(diào)查取得更深入的進(jìn)展前，我們不能回答這些問(wèn)題 中。 然而，在許多例子中，方向很難把握。如果用此喻來(lái)陳述不符合事實(shí)的情況 ， 例如，farther 的類似用法允許用于句子， 如Nothing could be farther from the truth, 而Notting could be futher from the truth 也是對(duì)的
