This morning I'd like to share a sentence pattern with you which is : S order that S should do. In this sentence, "order" means " to use your position of authority to tell somebody to do something or say that something mus happen". 译为：要求，指挥，命令。That S should do. 是宾语从句，谓语是should + 动词原形，可见这里使用了虚拟语气。凡是含有宾语从句的复合句中的主句中谓语动词是order, 且其作为“give instructions”下达命令这个意思的话，后面跟的宾语从句要用虚拟语气。此外，引导词that和情态动词should可以省略。注意了如果不是这个意思，就不能使用虚拟语气。
【例句及点评】
Let's look at some example sentences. The officer ordered they fire. 军官命令他们开火。注意这句话从句中省略了引导词that 和谓语中的情态动词should, 因此fire这里使用其原形，不要因为看到主句是ordered，使用的是一般过去式，就认为从句中也要用一般过去式，就使用fired。They ordered for every tree cut down two more trees be planted. 他们要求每砍一棵树就要补栽两棵树。这里要注意从句中省略了引导词that和谓语中的情态动词should，所以cut 和 be使用的是其原形。
【视野拓展】
Alright , except for "order" we have a word which is exactly similar to it. What's it? Let's look at the following sentence: He commanded that his men should retreat. Have you found it? It is : command which means"(of somebody in a position of authority) tell somebody to do something". 译为：(掌权者)命令某人做某事。So we should use subjunctive in an objective clause that follows it. For example: She commanded the prisoner be released. 她命令释放那个犯人。
