由动词last可以推测出询问“持续多久”，用how long，后句描述“持续到我们达成一致”，直到：until。
故选C。
2．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。
3．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。
4．B解析：B【解析】【详解】句意：虽然今天早上他起得很早，但他上学还是迟到了。
考查动词时态和连词。
get得到，活动，动词原形；got是get的过去式；gets是第三人称单数形式。
get up意为“起床”，是固定短语。
根据句中的时间状语this morning以及下句话“ he was still late…”可知，这句话说的是过去的事情，应用一般过去时态，先排除A和C。
句中Although是连词，引导让步状语从句，不能和but连用，因为but也是一个连词。
故选B。
【点睛】although 为从属连词，用来引导让步状语从句，它表明整个句子为复合句；but是并列连词，用以连接两个简单句使之成为并列句。
因此在同一句中不能既用从属连词 although，又用并列连词 but，两者留一个即可。
同理，because和so也不可连用。
5．D解析：D【解析】【详解】句意：虽然这篇文章有很少的生词，但我还是很难理解。
考查非谓语动词及连词。
understand理解；though虽然；because因为；if如果，是否，根据固定搭配have difficulty（in）doing sth做某事有困难，排除A和B，由后面的there are few new words in it和前面的句子have difficulty understanding the article可知，though最符合语境，排除C，故选D。
6．C解析：C【解析】【详解】句意：这个问题是如此的难以至于我们很少有人能回答。
考查such……that句型。
quite相当，后面接形容词原形；so如此，后面接形容词或副词，与that构成so……that句型“如此……以至于”；such如此，后面接名词或名词短语；very非常，后面接形容词或副词，根据所给空后面的a difficult question是名词短语，所以用such，故选C。
7．D解析：D【解析】【分析】【详解】句意：我不喜欢坚果，因为他们太硬了。
考察原因状语从句。
if表示如果，after表示在….之后，when当….时候，because因为。
根据句意，这里表示因果关系，所以选D。
