Answer 1

第1题正确答案是B，这就是一个简单的时间状语从句，当他回来的时候，还不到八点。而not...until....是直到。。。才的意思，而且后面都接从句，如：He didn't come back until it is 10 o'clock. 直到10点他才回来。
第2题正确答案是C，强调句式。it...that固定结构。
第3题选D，感觉travelling后面好象少了一个先行词，这是一个关系副词where引导的定语从句，在从句中作状语。
第4题正确答案是D，但是如果没有D这个选项，选A也可以。假如的意思。这句话就是一个态度非常坚决的反问：当你从来都不听课的时候，你还怎么期望学到什么？
第5题应该选D，当。。。时候，A项是自从。。。的意思，你翻译一下这句话就会明白：做作业是提到学习成绩的可靠的方法，特别是当进行考试时证明它是正确的。
第6题正确答案是C，作伴随状语，后面是非谓语动词形式，而while后面接从句。
