C exhausted

1：句子中，缺少状语。此处用exhausted 做伴随状语：你再初中学过有
tired but happy 和这里是一样的道理。tired 用做伴随状语
2: be suppose to =should 固定用法 意思为应该做某事
此处翻译为:再一个小时之前他就应该已经到达了，可以现在还没有出现
现在完成时是说明过去的动作对现在的影响。此处正是说明他一个小时之前没有来对现在的影响；所以选择c选项

另外，这个句子的主句是we finally reached what was called oasis。 Having walked in the desert for several days 是原因状语，用现在分词的完成式表达在沙漠里已经行走了好几天这个动作发生在找到绿洲之前，且这个动作与句子的主语we之间是逻辑上的主动关系，因此要用使用动词的-ing形式。
2 C 本应该做某事而未做 be supposed to have done sth. 或者 should have done sth. 本句意 他本应该在一小时前就已经到了的，但是他到现在还没出现。
3 A 考察现在完成时态 你是否已经带他参股了这家博物馆？回答：是的，我们在那过得很愉快。
现在完成时强调过去某个动作对现在的影响。
