高二学生~共勉（在知道里看到这些题觉得好亲切啊~）
lost pounds 发生在 realize 之前，为“过去的过去”，所以选过去完成时 had lost
2.这题考的是虚拟语气的省略和倒装，就是平常说的错综虚拟条件句
还原出原句为：If they were to arrive before we leave aftertomorrow,we should have a wonderfully dinner party. 对将来的虚拟
倒装是省略 if，并将Were前置
顺便说一句，如果是对过去的虚拟 if they had arrived……，则改为 Had they arrived~
3.consider在reject之前已发生且对reject有影响，所以用完成时作非谓语
doing作非谓语一般表示 伴随/结果状语
4.这里没有完成时的时间标志，没有说动作对现在的影响，也没有强调动作的延续性，只是陈述客观事实，所以不需要用完成时态，一般过去式就可以表示陈述客观事实
（这个很容易错，要注意~）
5.should have done 本应该左耳未作
could have done 本能做而未做
这里没有约定条文之类的，也不是义务，所以不需要should
“我本来可以给你提供资金的，你为什么不找我呢”
6.问题在 have stayed 和be staying 上，由语境推断，因为 stay in America 造就了 fluent English
stay in America 先发生且有影响，所以用 must have done 表示对过去的肯定推测
7.题目中有时间提示 now，所以选A would not be（表示对现在虚拟）
如果是 problems+过去时间，则选B
8.你已经选了被动语态，只要记住：固定搭配 admit to doing （to 为介词~）
加油哦~
第二题， Were they to arrive意思是要是他们能到达，这个只能靠你个人知识面才能做出选择
第三题，AB先抛弃，在CD间选择，整句话意思是“经过深思熟虑后，他放弃了那个计划”，带有被动性，所以选C
第四题，根据语境，B和D先抛弃，剩下AC，如果不知道单词意思的话确实难选择，但如果知道的话，就很好选择，witnessed是witness的过去式和过去分词，在这里的意思是目睹，既然是目睹，突出的自我主动性，而不是被动性，所以不选A
第五题，provide sb with sth 前半句意思是我们能够为你提供资金，在这个语境中，could最合适，其它的三个选项表达的是一定、应当，根本不符合语境
第六题，AB首先抛弃，CD选一个，唯一的区别是后半句，be staying是正在进行时，而语句表达意思是过去时，所以选C，整句话的意思是：从他流利的英语可以看出，他已经在美国待很长时间了
第七题，整个语句是过去式，C首先抛弃，BD选项语句错误，也抛弃，所以选A，
第八题，这个题目很多单词我也不懂，但是句中两个单词决定了答案，是“to”"by"，by说明是被动，那么先把B和D抛弃，就剩A和C，to后面是不能直接跟被动词的，所以加个being,所以选C
