    The government has taken some measures to solve the problem of unemployment, but it may be some time ______ the situation becomes better.
    A．beforeB．sinceC．afterD．unless
    A

    试题分析：考查连词用法。“It be+一段时间+before…”是固定结构，该结构的意思是“要过……（长）时间才……”。when“．．．．．．的时候”；since“从．．．．．．开始”；unless“除非”；根据题意：政府已经采取措施解决失业问题，但是还要一段时间形势才能缓解。D最佳。
