A. encourage鼓励；B. challenge挑战；C. introduce介绍。
根据句意：你邀请他们去战斗或者和他们在某方面竞争，可知是“如果你挑战某人”，“挑战”challenge。
分析题干可知这是if引导的条件状语从句，要遵循“主将从现”的原则，所以if从句要用一般现在时，故答案选2．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。
3．A解析：A【解析】【分析】【详解】句意：Jenny经常吃很多蔬菜和水果，因为她知道它们对健康有利。
本题考查连词。
A. because 因为，表原因； B. but但是，表转折； C. or或者，表示选择。
分析句子知，“Jenny经常吃很多蔬菜和水果”，是结果，“她知道它们对健康有利”表示原因；故选A。
4．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。
5．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。
解析：D【解析】【分析】【详解】句意：这个小女孩正在哭，因为她找不到她的父母了。
考查连词。
根据句意可知，小女孩哭的原因是找不到父母了，所以后句表示哭的原因。
and 并列连词，并且；but并列连词，但是，表示转折；so连词，因此，表示结果；because连词，因为，表示原因。
根据句意，故选D。
7．D解析：D【解析】【详解】句意：我不明白这个女人尽管有一份高薪的工作和一个幸福的家庭她还经常抱怨。
whenever无论什么时候；since自从；既然；until直到……时候；though尽管。
根据句意空前的complains与空后a well-paid job and a happy family是转折的关系，应用though引导让步状语从句。
故选D。
8．B解析：B【解析】【分析】【详解】句意：—你认为我是否适合这份信息技术工作？—除非你有计算机行业的经验，否则你不会得到这份工作。
考查连词。
if如果；unless除非；because因为；since自从…以来。
作为问句的答语，句子“You can’t get the job”和“you have experience in the computer industry.”是条件关系。
只有从选项A和B中选择。
