B．as

C．however

D．even if
请问这题选什么，如果可以的话说下详细解析谢谢了

Answer 1

选 as
complicated as it is
就是 尽管它很复杂 的意思
整个句子就是，尽管这个问题很复杂，它还是可以用电脑在两个小时内解决。
希望我的回答能够得到你的采纳

Answer 2

答案是第2个as。
Complicated as it is

这是一个as引导的让步状语从句,as的意思是尽管。可换成though,但不能用although

Answer 3

答案选 B，as。as引起让步状语从句时，意思是＂虽然＂，句子需要倒装。倒装的做法通常有四种：1，名词做表语提前，如：Child as he was, he could speak two languages. 2, 形容词作表语提前，如：Sad as he was, she smiled to them.
3, 部分谓语动词提前，如：Try as you might, you could not succeed.
4, 副词提前，如：Hard as you work, you can't support your family.
你的这个题目属于第二种，形容词作表语提前。

Answer 4

Complicated______it is,the problem can be solved in only 2hours with an electronic computer.尽管这个问题很复杂，但用电子计算机只要两小时就能解决。
选择B as，因为这里是一个as 引导的倒装句，表示让步状语从句。，其他选项不能引导倒装句。

Answer 5

B
adj+as it is，倒装强调句。“尽管它xxx，”
