1It remains ______ whether Jim will be fit enough to play in the finals.
A．seen B．to be seen
C．seeing D．to see
解析：本题考查非谓语动词的用法。remain 为系动词，后可接不定式作表语。根据句子结构可知，it 为形式主语，whether从句为真正主语。“Jim是否适合打决赛还有待观望”，因此应用不定式的被动语态。
答案：B
2There was never any time for Kate to feel lonely，______ she was an only child.
A．ever since B．now that
C．even though D．even as
解析：句意：“尽管凯特是个独生女，她从来没觉得孤独。”ever since“自从……以来”；now that“既然”；even though“虽然，尽管”。只有C项符合句意。
答案：C
