单句语法填空
1．If the new safety system (bring) into use, the accident would never have happened.
had been brought 解析：句意：如果新的安全系统已经投入使用，事故就不会发生了。根据句意、句子结构以及主句中的would never have happened可知，句中If引导的是虚拟条件句，且表示与过去的事实相反的假设，故从句时态应用过去完成时。
2．When you phoned me, I was having a meeting; how I wish I (answer) your call.
had answered 解析：句意：当你给我打电话的时候，我正在开会。我多么希望我(之前)接了你的电话。wish后的从句中用虚拟语气，根据句意可知是对过去情况的虚拟，所以谓语动词用had done形式。
3．As the deadline is drawing near, no one leave with his own work uncompleted.
shall 解析：句意：因为截止日期即将到来，不完成工作，任何人不许离开。shall用于第三人称陈述句中，表示命令、警告，符合句意。
4．The order came that the medical supplies (send) to the earthquake-stricken area soon.
(should) be sent 解析：表示建议、要求、命令等名词，如：suggestion, order, request, advice等后接的表语从句、同位语从句中谓语动词用(should＋)动词原形。
5．It is high time that you (consider) that if there were no stress in your life, you would achieve a little.
considered/should consider 解析：在It is high time that...句式中，从句用虚拟语气，即：谓语动词用过去式或should＋动词原形。
6．I was ill that day, otherwise I (take) part in the sports meet.
would have taken 解析：句意：那天我病了，否则我就参加运动会了。根据语境可推知，设空处为与过去事实相反的虚拟语气，故答案为would have taken。
7．—I (not) thank you enough for what you have done for me. —You’re welcome.
can’t 解析：句意：——你为我做的一切我无论怎么感谢都不为过。——不用谢。can
not...enough表示“再……也不为过”。
8．Harry is feeling uncomfortable. He have drunk too much at the party last night.
must 解析：句意：Harry觉得不舒服，他昨晚在聚会上肯定喝太多了。由last night及语境可知，此处表示对过去的肯定情况把握较大的推测。must have done sth.“一定做了某事”。
9．John wants to see me now, but I have so much work on hand that I would rather he (come) tomorrow than today.
came 解析：句意：约翰现在想看我，但是我手头有很多工作要做，我宁愿他明天来而不是今天。would rather后面接从句，用虚拟语气，和现在或将来相反用一般过去式，和过去相反用过去完成时，故填came。
10．As Father and Mother thought it was a big occasion for me, they suggested I (hold) a birthday party at home to celebrate it.
(should) hold 解析：suggest表示“建议”时后面宾语从句的谓语动词应用(should＋)动词原形，故填(should) hold。
