考查连词，A. Though尽管，虽然，引导让步状语从句；B. Because因为，引导原因状语从句；C. But但是，表转折。
观察句子逻辑结构，应该是though引导的让步状语从句，故选A。
【点睛】though、although均引导让步状语从句，意为“虽然……”，although较正式，though最常用。
如：Thouth (Although)he was tired,he kept on working.注意：though、although引导的从句不能与but、however连用，但可以与yet、still连用。
though还可以与别的词结合使用，如even though、 as though,而although则不能这样搭配。
2．C解析：C【解析】【详解】句意：如果你去佘山，你会看到一个著名的教堂和一个天文台。
考查连词辨析。
Although虽然；What什么；If如果；Because因为，根据所给空后面的从句you go to Sheshan是一般现在时，主句you’ll see a famous church and an observatory是一般将来时，由“主将从现”可知，应该用的是if，引导条件状语从句，故选C。
3．A解析：A【解析】【详解】句意：昨天早上我遇到我的第一个老师时，我正在公交车站等车。
考查时态辨析。
由“yesterday morning”可知题干时态为过去时。
when引导的时间状语从句缺谓语动词meet “遇见”，结合句子时态，填其过去式met；又“when+时间状语从句”表示的是一个时间点，在当时那个时间点强调主人公“正在等”，用wait的过去进行时形式was waiting，故选A。
【点睛】过去进行时常和when，while引导的时间状语从句连用，表示“在……的时候，某人正在做或某事正在发生”。
其中when后引导的时间状语从句谓语动词可以是短暂性动词，也可以是延续性动词，但while后的时间状语从句谓语动词只能用延续性动词。
大家在做题时注意结合语境判断好时态和动词的特性。
4．C解析：C【解析】【详解】句意：我们所有人都不喜欢这个游戏，因为太无聊了。
考查连词。
A. and并且；B. so所以；C. because因为。
不喜欢的原因是无聊，陈述原因用because引导原因状语从句，故选C。
5．C解析：C【解析】【详解】句意：我昨晚在一个酒吧看世界杯，直到凌晨1点才回家。
考查连词。
根据时间状语last night，可知用一般过去时，所以排除AD；根据句意，可知是not…until…引导时间状语从句，意为“直到……才……”，故选C。
6．B解析：B【解析】【详解】句意：李雷昨晚直到他妈妈回来才睡觉。
考查连词辨析。
after在……以后；until：直到；because因为。
连词短语not…until：直到……才……；结合句意可知选B。
7．B解析：B【解析】【详解】句意：当她省钱的时候，她想做什么？考查时态。
is going to save一般将来时；saves一般现在时；will save一般将来时。
