A．Now that

B．Until

C．Provided that

D．Although

Answer 1

C

试题分析：考查连词：A. Now that既然B. Until直到C. Provided that条件是，如果D. Although虽然，句意：只要你不在外面待得太晚，你就可以去参加聚会，但是记住不能迟于11：30回来。选C。
点评：这几个词都是连词，要分清每个连词短语的含义和用法，做题时关键看上下文和句意的逻辑关系做题。表示条件的连词还有：as long as，unless，on condition that，suppose that，supposing that等。
