根据语境可知，第一个when引导的是时间状语从句，主句用一般将来时，从句应用一般现在时；第二个when引导的是宾语从句，表示的是一个即将发生的动作，应用一般将来时。
结合选项可知应选A。
考点：考查从句的时态问题。
2．B解析：B【解析】试题分析：句意：——西莉亚，如果这个周末不下雨的话，就来加入我们的超级夏令营吧。
——我非常乐意。
但是没有人知道周末是否会下雨。
第一句中的连词if意为“如果”，用来引导条件状语从句，从句用一般现在时表示将来，故用is fine；第二句中的if意为“是否”，引导宾语从句，根据句意从句用一般将来时will rain。
故选B。
考点：考查条件状语从句的用法和宾语从句的用法。
3．A解析：A【解析】【详解】句意：当我们打游戏的时候，我们总是无法意识到时间的流逝。
考查从属连词以及状语从句。
while当……时，时间状语从句；although尽管，让步状语从句；unless除非，如果不，条件状语从句；if如果，条件状语从句。
当我们玩游戏时候，我们意识不到时间过得很快。
时间状语从句，故选A。
4．A解析：A【解析】句意：----你能告诉我你什么时候到吗？-----我不确定。
但我明天一到那儿就给你打电话。
A. arrive一般现在时；B. arrived一般过去时；C. will arrive一般将来时；D. am going to arrive一般将来时。
as soon as引导的时间状语从句表将来的事时，这时主句用一般将来时，从句用一般现在，即：主将从现。
本句主句是一般将来时，从句用一般现在时，故选A。
5．B解析：B【解析】句意：尽管许多人通过网络获取最新消息，但是很可能报纸不会消失。
Because因为，引导原因状语从句；Though尽管，引导让步状语从句；Since自从，引导时间状语从句；Unless除非，引导条件状语从句。
根据两句话之间的逻辑关系可知应选B。
6．A解析：A【解析】【详解】句意：只要你每天做锻炼，你能保持健康。
A. as long as只要；B. so因此；C. as soon as一……就，根据下文you exercise every day.只要你每天做锻炼，这里用as long as引导的条件状语从句。
根据题意，故选A。
7．C解析：C【解析】【详解】句意：——你知道这场会议将会持续多长时间？——直到达成协议。
考查疑问词辨析以及连词。
How long多长时间；when什么时候，until直到；not until放在句首时，句子要倒装，根据第一个空后面的the meeting will last可知，应该是多长时间，排除B和D，由第二个后面的句子the agreement is reached可知，应该用的是until直到，用来表示时间段，排除A，故选C。
