12、 _ right,though the others didnt think so.Ashould do Bshould have done Chad done Ddid,答案与解析,（二）,1选B。分析见本章语法说明。2选D。本句带有要求之意，故从句谓语用should型虚拟语气。D项中的should被省略。3选C。本句也带有惊讶之意，故从句须用should型虚拟语气。但由于是过去的事情所产生的惊讶，所以用should+不定式完成式。4选D。如选A，这表达了说话人对将来的事所发出的感叹，选B则是对已经过去的事情的感叹。选C则是一个直陈语气，即说话人对此并不一定感到十分惋惜，而是对此事的陈述。5

13、选D。insist在作“坚持要求别人做某事”时，需要用should型虚拟语气，should也可以省略。6选C。insist在作“坚持自己的观点、看法等”解时，不需要用虚拟语气，所以A、B两项用在此处不当。D项时态不准确，故也应排除。,7His pale face suggested that he _ the sad news.Ashould be told Bshould have been told Cwas told Dhad been told 8He suggested that we _ here at once.Ashould leave Bmust leave Cleft Do

14、ught to leave 9My order is that everyone _ their own work in time.Amust complete Bcompleted Ccompletes Dcomplete 10Weve made the decision that we _ at the school gate at 7 tomorrow morning.Awill gather Bare about to gather Cwould gather Dshould gather 11-Ill be waiting for you at home.-_ I were busy

15、 and couldnt come?AWhat if BWhat when C How if DHow when,答案与解析,7选D。suggest作建议解时，后接了should型虚拟语气，但在本句中作“表明”解，这时不用虚拟语气，A、B两项都应排除，C项时态不当。8选A。在本句中suggest作“建议”解，故选A。9选D。“建议”、“命令”、“要求”等动词的名词形式做主语时，其表语从句也须用should型虚拟语气，本句中的should被省略。10选D。上述提到的这些词后接同位语从句时也须should型虚拟语气。11选A。What if？常用于省略疑问句，既可以用于虚拟语气，也可用于直陈语气。

16、本句不省略的形式为What would you do if。,12选B。本句的under引出一个非真实的条件，当然也可以是真实条件。根据上下文，应理解为与过去事实相反，故其谓语动词用would have done。13选B。even though=even if意为“即使”。它同if一样可以引出一个真实的让步从句，也可以引出一个非真实的让步从句。根据上文，even though是一个非真实的与过去事实相反的让步从句。而主句wecant get there却是一个真实的情况。14选D。参阅A层次试题（一）中的第10题。,15选D。从全句的意思分析，a ture friend-differently实际上是指一种假设，而when引导的从句又告诉我们，这是一个与过去事实相反的假设，故用would have acted。16选D。even if引导一个非真实的让步从句，而主句用肯定是不合逻辑的，因此，选D。,
