“[误]Complicated though the problem is, it can be solved in only two minutes with an electronic computer.
[正] Complicated as is the problem it can be solved in only two minutes with an electronic computer.
[译文]虽然这个问题很复杂,但是用一台电子计算机只需两分钟就能解出。
[解释]倒装式的让步状语从句的句型为: 表语 + as + 主语代词 + 连系动词, 或表语 + as + 连系动词 + 主语名词。虽然在此句型中 as 的意义和 though 相同, 但是却不能用 though 代替。”(《英语正误详解词典》, 复旦大学出版社, p. 694)
请问上面的说法正确吗？
这是我国很常见的说法(见 )。但是，这种说法是不正确的。其实，though也可以用在上面的异常语序的让步从句中，代替as。可以见到以下几种情况：
A. 形容词(或副词) + though + 主语 + 连系动词或实义动词:
-
Rich though he is, he is not happy. 虽然他很富有，但是他并不幸福。
-
Tired as they were( =Tired though they were), Jurgis and Ona sat up late. 尽管朱尔金斯和奥纳很疲惫, 但是他们很晚才睡。
-
Much though I admire her, I cannot excuse her faults. 虽然我非常崇拜她，但我不能原谅她的错误。
-
Happy though the bride is, she will feel homesick in the beginning. 虽然新娘很欢乐，但是开始时她会想家的。
B. 名词(不带冠词) + though + 主语 + 连系动词 be:
-
Genius though she was, she was quite unassuming. 虽然她是个天才，但是她很谦逊。
-
Coward though he is, do not bully him. (Curme) 尽管他是个胆小鬼，但不要欺侮他。
C. 实义动词 + though + 主语 + 助动词 [如果没有助动词, 则要加上一个 do (does 或 did)]:
-
Change your mind though you will, you will gain no additional support. 即使你要改变主意，你也不会得到另外的支持。
-
Fail though I did, I would not abandon my goal. 虽然我失败了,但是我不会放弃我的目标。
