[答案与解析]
1．While。句意：John在看电视，而他的妻子在做饭。此处表示前后两种情况的对比，故填While。
2．unless。考查条件状语从句。句意：除非你完全致力于你的工作，否则你将永远不会获得成功。根据句意可知，完全致力于工作是成功的条件，故填unless。
3．that。考查原因状语从句。句意：既然大家都到齐了，那就让我们开始英语晚会吧。now that既然。
4．since。考查时间状语从句。句意：自我从国外回来以后，我就听说了很多关于你的好事。since“自……以后，从……以来”，引导时间状语从句，主句常用现在完成时，故填since。
5．when。考查时间状语从句。句意：当我父亲叫醒我看足球比赛时，正好是半夜。结合句意可知，空处引导时间状语从句，表示“当……时”，故填when。
6．Although/ Though / While。考查让步状语从句。句意：虽然/尽管学生们来自不同的国家，但他们在夏令营中相处得很好。此处引导让步状语从句，表示“虽然，尽管”，故填Although / Though / While。
7．However。考查让步状语从句。句意：不论你怎么努力，如果不减少饭量，你就很难减肥。空后面的hard是副词，所以用however修饰，表示“无论如何”，故填However。
8．so。句意：有些动物把种子从一个地方带到另外一个地方，因此植物就可以传播到新地方了。根据carry seeds与spread to new places可知，两个分句之间存在因果关系。so表示因果关系，意为“因此，于是”，符合要求。故填so。
9．where。考查地点状语从句。句意：如果你碰巧在野外迷路了，最好待在原地，等待帮助。分析句子结构可知，句中缺少地点状语，表示“在……的地方”，故填where。
10．before。句意：他们长时间工作了好几个星期，一切才恢复正常。before在此引导时间状语从句。当主句谓语动词强调动作的持续性，常伴有时间段状语或时间段暗示，例如本句中的“long hours for several weeks”，故填before而不填until。
11．Once。考查条件状语从句。句意：一旦损害造成，农田恢复将需要很多年的时间。根据句意可知此处表示“一旦”，故填Once。
12．though/if。考查让步状语从句。句意：他很忙，即使他想陪他的儿子也没有足够的时间。even if/though引导让步状语从句，表示“即使”，故填though/if。
13．As。句意：随着人口平均年龄的增加，越来越多的老年人需要照顾。根据句意可知此处表示“随着”，故填As。
14．that。句意：他说话很慢，很奇怪，因此需要耐心弄明白他所说的意思。本句运用了句型so...that...(如此……以至于……)，故填that。
15．until。句意：直到知道了主角的结局，那个女孩才舍得放下书。not...until...直到……才……。
16．If。句意：如果我们想要在日落前到达芝加哥，这就意味着我们不得不在明天黎明就出发。此处表示条件，故填If。
17．immediately。句意：那个男人一被带进房间我就认出了他。immediately“一……就……”。
18．as。句意：一些种类的花在夜间收拢，好像它们这么做是为了要睡觉一样。根据语境可知，空处引导方式状语从句，故用as if“仿佛，好像”。
19．in。句意：如果你去徒步旅行，你不得不带着一些必要的东西例如绳子、手电和靴子，以防你在山里迷路了。in case“以防；万一”。
20．Whatever。句意：无论你捡到什么，你必须把它还给它的主人。Whatever引导的是让步状语从句，在这里相当于No matter what。
