5. didn't;until

解析

【分析】本题是根据汉语提示完成句子的基础题型,需结合汉语语义,回忆对应的英语固定句式、连词及短语,同时注意时态和句子结构:1题对应“not...until”(直到...才)的固定结构,需用过去式;2题涉及if引导的条件状语从句,遵循“主将从现”规则;3题需用让步状语从句连词,以及“have trouble/difficulty doing sth”(做某事有困难)的固定搭配;4题考查“set off”(出发)和“so that”(以便)的用法;5题再次考查“not...until”的过去式用法。
【解析】1. “直到...才”的英语表达为“not...until”,句中时间状语“Last night”表明是一般过去时,因此助动词用didn't,故填didn't;until。2. “如果”对应连词If,引导条件状语从句,该从句遵循“主将从现”原则,主句用一般将来时,故填If;will。3. “尽管”对应让步状语从句连词Although/Though;“做某事有困难”的固定搭配是have trouble/difficulty doing sth,结合过去时态,故填Although/Though;had trouble/difficulty learning。4. “出发”的固定短语是set off,情态动词must后接动词原形;“以便”对应目的状语从句引导词so that,故填set off;so that。5. “直到...才”用“not...until”,句中时间为过去,助动词用didn't,故填didn't;until。
【答案】1. didn't;until 2. If;will 3. Although/Though;had trouble/difficulty learning 4. set off;so that 5. didn't;until
【知识点】not...until结构、条件状语从句、固定搭配(have trouble doing sth)
【点评】本题聚焦初中英语核心基础句型与短语,是日常学习的重点内容,主要考查学生对常用句式的掌握程度,难度适中。
