Because I have a very impo.e you this evening,( )I'd like to

1.答案：D.
2.翻译：因为有一个非常重要的会议要参加,我今天晚上不能来见你,尽管我非常想要(去见你).
3.此题考查as引导让步状语从句时倒装结构的语法.
1）如果as意为“尽管/虽然”,引导让步状语从句时,该从句必须采用倒装句型：一般是把从句的表语/状语/谓语或形容词/副词/名词/动词提前至从句句首,其他顺序不变.
如：Child as he is,he knows a lot.
Old as my grandpa is,he is in good health.
2) 此题的状语从句的正常句序为：as I'd like to (come to see you) (very) much
且此句中的much表程度,修饰see you,意思是“非常想来见你”.
所以只需要把程度副词much提前即可,即：much as I'd like to (come to see you)
另：come to see you为主句中已经出现的短语,所以可以省略.
