| 单词 | 若非 |
| 释义 | 〔but〕With the exception that; except that. Used to introduce a dependent clause:若非：除非；除此。用于引导一个独立的从句：〔couple〕Although the phrasea couple of has been well established in English since before the Renaissance, it has been criticized on several grounds.Grammarians used to insist thata couple of should be used only to refer to things closely linked to one another and so was improperly used in phrases such asa couple of years ago. This objection has not been heard in some time and was never well supported.Modern critics have sometimes maintained thata couple of is too inexact to be appropriate in formal writing. But the inexactitude ofa couple of may serve a useful communicative purpose, suggesting that the writer is indifferent to the precise number of items involved.Thus the sentenceShe lives only a couple of miles away implies not only that the distance is short but that its exact measure is unimportant. Furthermore,a couple of is different from a few in that it does not imply that the relevant amount is relatively small. One might say admiringly of an exceptional center fielder thathe can throw the ball a couple of hundred feet, but not, except ironically,a few hundred feet, which would suggest that such a throw was unremarkable. The usage should be considered unobjectionable on all levels of style.尽管a couple of 这个短语在文艺复兴之前就已在英语中形成， 它仍受到多方面批评。语法学家过去坚持认为a couple of 应该只用于指互相之间紧密相连的东西， 所以在a couple of years ago 这样的短语中用是不适当的。 这样的反对意见长时间没有人提起了，也从未受到太多支持。现代批评家有时也认为a couple of 太不精确，不能很恰当地用于正式的写作中。 但a couple of 的不精确性也有一种很有用的传达交流的意图， 表明作者对于所涉及的事物的精确数目并不太关心。因此她住的只有几英里远 这个句子不仅表明距离很远，同时也表明精确测量是不重要的。 另外a couple of 与 a few 的不同还表现在它不表示有关的数量是相对来说小的。 如果夸赞一个优秀的中外野球手，可以说他能把球抛几百英尺远 ， 若非如此的话，排除反意的可能，a few hundred feet 指抛这么远并没什么稀奇之处。 这种用法在各种文体上都是无可辩驳的 |
