10、ardly succed。)，4.2 as if/as though，Even if/even though子句中的虚拟。如果指现在的情况，以过去时态(用于be的were)指过去发生的行为，则谓语动词是had+过去分词，would (should，could)动词原形She looks as if/though she were ill。看她的样子好像病了。He walks as if he were a king。他走来，好像他是国王一样。He acted as if nothing had happened .他什么事都没做。he would not resign even if the
