考查连词辨析。when当；until直到；after在……之后。根据“Many students didn’t realize the importance of study...they left school”可知是直到离开学校才意识到学习的重要性，not...until“直到……才”。故选B。
50．C
学生们应该待在座位上直到所有试卷都收齐为止。
考查连词。as soon as一旦；if如果；until直到；although尽管。根据“Students should stay in their seats...all the test papers are collected.”可知，应表达直到所有的试卷都收齐，应用until引导时间状语从句。故选C。
51．look back on
对照中英文可知，缺少“回首”，用look back on。此句为when引导的时间状语从句，主句时态为一般现在时，从句表示现在发生的具体动作，也为一般现在时。主语为复数的we，谓语动词用原形。故填look back on。
52．didn’t make a decision
根据汉语句子及“until her teacher gave her some advice”可知，该句为not… until…引导的时间状语从句，表示“直到……才……”；又因为从句是一般过去时，根据“主过从过”的原则，主句也应是一般过去时；动词短语make a decision“做出决定”的否定形式需要借助于didn’t。故填didn’t make a decision。
53．check
根据中英文对照可知，check “检查”；主句是祈使句，when引导时间状语从句时，从句用一般现在时，主语you，谓语动词用原形。故填check。
54．won’t know the result of the match until the end /won’t know the result of the game until the end
根据中英文对照可知，语境时态是一般将来时。not...until...“直到……才……”；know the the result of the match/game “知道比赛的结果”；until the end“直到最后”。故填won’t know the result of the match until the end/won’t know the result of the game until the end。
55． don’t know/understand until
know/understand“理解，明白”；not...until“直到……才”；分析句子可知，此句为一般现在时，主语是复数，否定用助动词don’t，后跟动词原形。故填don’t；know/understand；until。
56．as soon as/once/the moment
根据中文提示可知，此处应填时间状语从句的连接词，“as soon as”、“once”和“the moment”都可以表示“一……就……”。故填as soon as/once/the moment。
57．didn’t get up until
分析句子可知，此处需要翻译的是“直到……才起床”，直到……才：not…until，固定短语，until引导时间状语从句；起床get up，是动词短语。句子的时态为一般过去时，是否定句，要借助助动词did，再加not，其后用动词原形。故填didn’t get up until。
58． To our surprise after his death/after he dies
to one’s surprise“令某人惊讶的是”，our“我们的”,位于句首首字母需大写；after his death/he dies“他死后”。故填To our surprise；after his death/he dies。
59． don’t/never until
“直到……才”用“否定词+until”结构表示，时态是一般现在时，主语是“We”，否定用don’t或never。故填don’t/never；until。
60． didn’t make the decision/didn’t make a decision gave him some advice
not...until...“直到……才……”，引导时间状语从句，因此主句用否定形式，make the/a decision“做决定”，give him some advice“向他提出了一些建议”，advice“建议”，不可数名词；分析语境可知，句子用一般过去时，主句用助动词didn’t，从句谓语give变为过去式gave。故填didn’t make the/a decision；gave him some advice。

一个句子中如果缺少谓语动词，除了需要考虑时态以外，还需注意主语与谓语动词之间是主动还是被动关系，从而判断是否需要用被动语态。例如本题，根据句意是要等到有人叫你，因此是sb. call you，所以you和call之间是被动关系，故能很快得出答案选D。

52．didn’t make a decision
根据汉语句子及“until her teacher gave her some advice”可知，该句为not… until…引导的时间状语从句，表示“直到……才……”；又因为从句是一般过去时，根据“主过从过”的原则，主句也应是一般过去时；动词短语make a decision“做出决定”的否定形式需要借助于didn’t。故填didn’t make a decision。

57．didn’t get up until
分析句子可知，此处需要翻译的是“直到……才起床”，直到……才：not…until，固定短语，until引导时间状语从句；起床get up，是动词短语。句子的时态为一般过去时，是否定句，要借助助动词did，再加not，其后用动词原形。故填didn’t get up until。
58． To our surprise after his death/after he dies
to one’s surprise“令某人惊讶的是”，our“我们的”,位于句首首字母需大写；after his death/he dies“他死后”。故填To our surprise；after his death/he dies。
59． don’t/never until
“直到……才”用“否定词+until”结构表示，时态是一般现在时，主语是“We”，否定用don’t或never。故填don’t/never；until。
60． didn’t make the decision/didn’t make a decision gave him some advice
not...until...“直到……才……”，引导时间状语从句，因此主句用否定形式，make the/a decision“做决定”，give him some advice“向他提出了一些建议”，advice“建议”，不可数名词；分析语境可知，句子用一般过去时，主句用助动词didn’t，从句谓语give变为过去式gave。故填didn’t make the/a decision；gave him some advice。
