It is ________ that he ________ the football club.
A.for two years; took part inB.since two years ago; joined inC.two years ago; joinedD.in two years time; attended在线课程C
观察题干，可确定是考查强调句型。强调句式中如去掉It is/was…that/who这几个词，适当调整词序可还原成一个完整的句子。故此题应选C。原句可还原成：He joined the football club two years ago.根据“非延续性动词不跟段时间连有”可排除A、B、D。
