| 词组 | but |
| 释义 | 1．许多修辞学书里说句首不可用 but，其实句首用 but 很普通。即使用在一段文字的开首也可以。 2．though ... but ...和 although ... but ...都是错误的，该把 but 改作 yet 或删去。 3．but ... however 不该用，如不该说 But that, however, is quite different，该改作 But that is quite different 或 That, however, is quite different。 4．No man but I saw him 和 No man but me saw him 都可以说，意思也相同，现在在文字里用 I 普通些，在口语里用 me 普通些。第一句里的 but 是连接词，第二句里的 but 是介词。 5．not ... but ...是习语。例如：It is not black, but white.但该注意这习语很容易用错，如说 It is not black, but it is white 便大错了。 6．not ... but ...是习语，not so much ... as ...也是习语，not so much ... but ...是错误的（英美人往往有这种错误），如 I admire him not so much for his learning as for his character（我羡慕他，与其说为了他的学问，不如说为了他的品格）里的 as 不可改作 but。 7．can but 和 cannot but 意思略有不同。can but 作“只能”解，如 I can but wait 是说“我只能等着（没有别的事可以做）”，有时有“至多不过……”的意思，如 I can but lose that money 是说“我至多失了那笔款子，并不会有其他不幸的事情发生”。cannot but 作“不得不”或“不禁”解，如 I cannot but think so 是说“我不得不这样想”。 can but 和 cannot but 都是比较正式的短语，在口语里通常不用 can but 而用 can only，不用 cannot but 而用 cannot help ...ing 或 cannot help but。 8．do nothing but 或 do anything but 后面接没有 to 的不定式，如 I could do nothing but wait 和 I could not do anything but wait。 9．all but perfect 是“几乎完美的”，anything but perfect 是“极不完美的”。 10．下面每组里的四句意思相同： 每组里的第一句和第二句里的 but 是关系代词，第三句和第四句里的 but 是连接词。 |
