1. 选[c]该题考察表示惊奇、高兴、遗憾、担心等感情色彩的形容词引起的主语从句中的虚拟语气的表达。在

anxious,sorry,concerned,happy,delighted等表示感情色彩的形容词后接的that 从句中，用should来修饰谓语动词。该句中有strange 一次，意为“奇怪”，表示对事物的惊讶或不满，it为形式主语，that 从句为主语从句，要求从句中用虚拟语气的表达形式should+动词原形表示

2. 选[c]该题考察it’s+adj.+that主语从句的虚拟形式。观察句子结构可以看出这里为It’s+形容词(important)+that从句结构，形容词important做表语，主语从句需要虚拟形式should+动词原形，should 可以省略

1. 选[a]该题考察非真实条件的虚拟。在表示过去情况的虚拟条件句中，条件从句用了过去完成时形式，主句可用

should(would/could/might)+have+过去分词的形式

2. 选[a]该题考察含蓄条件的虚拟。But for含义为“要不是”，用于此处可以表达假设条件，

but forhis timely arrival=If it had not been for his timely arrival或If he had not arrived on time.

1.My hat was here a second ago but now it’smissing.Someone____ __(一定在跟我开玩笑)!”

2.His advice has made the design_______(比它原本会是的样子更好)

Answer：

1.must have made a joke about me

【解析】该题虚拟条件句的使用。本句是对过去事实的推测。观察句子可以看出这里为对过去的事实的肯定推测，应用must+have done 结构，句中someone 与make 之间为主动关闭。

2.better than it would otherwise have been

【解析】该句考察含蓄条件句的虚拟形式。otherwise相当于虚拟条件if it hadn’t been for hisadvice,表示对过去的一种虚拟，所以要用would otherwise have been.

1.选[a].该题考查定语从句引导词前介词的选择。定语从句可以由“介词+which/whom”来引导，介词的选择取决于从句动词的搭配关系以及从句本身的意义。本题中which代表前面的one hundred languages,根据句意，其中14种被定为官方语言，这是一种部分与整体的关系，所以关系代词前面的介词要用of.

2.选[d].该题考察非限定性定语从句。观察句子结构及四个选项可以
