请问二者的区别

举报且听殇败

was supposed to 是suppose这个词的过去式，而is supposed to have done 是done 这个词的过去式所以当你说， he was supposed to come. 那可能说昨天晚上，他应该回来的。但他没来。这个应该发生在过去而你刚才那个句子，是现在讲的，两小时钱就应该来的，但到现在还没来

he was supposed to come这个句子后面可以加 two hours ago 吗，问题二promise 后面的从句虚拟吗

不可以啊，但我解释不清楚为什么，呵呵

那从何得到的结论呢，promise后面有虚拟吗，高手

语感咯，向来都是直接选择，从来不想那么多为什么，要那么多语法理论有什么用，会说会用是实际

要考试怎么办呢

考试就是多做题啊，做熟了直接就选了，当年高考，姐就花了一半时间就做完了，全班第一还是第二来着忘了
