以下是难句翻译，依然是针对六级高频考点—虚拟语气进行练习，虚拟语气是六级的常考语法

1.When I think about all the problems of our overpopulated world and look at our boy grabbing at the lamp by the sofa,I could have turned to Planned Grandparenthood when my parents were putting the grandchild squeeze on me.

2.If I correct someone,I will do it with as much good humor and self-restraint as if I were the one being corrected.

3.”My hat was here a second ago but now it’s missing.Someone______(一定在跟我开玩笑)!”

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

1.【解析】该题考察对过去情况的虚拟

【句意】当我想到有关世界人口过剩的所有问题，看着我们儿子抓沙发旁的台灯时，就在想如果那时在父母逼着台灯时，就在想如果那时在父母逼着我生孩子的时候，自己能够求助于“有计划地成为祖父母”组织就好了。

2.【解析】该题考察as if虚拟语气在状语从句中的使用。大家要注意从句中系动词的使用形式为were

【句意】如果我要纠正别人，我会采取和蔼克制的态度，好像再纠正自己一样。

3.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。

4.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 his advice,表示对过去的一种虚拟，所以要用would otherwise have been.
