补充资料 宾语从句中的虚拟语气
补充资料：虚拟语气(should)+动词原形
that宾语从句需用(should)+动词原形表示虚拟的动词；
advise, recommend, propose, suggest, insist, command, mandate, direct, order, ask, demand, request, require, insist, maintain, move, refer, desire, urge, vote
that不可以省略；should可以省略；
以上动词的同词根名词在that同位语从句和表语从句需用(should)+动词原形，如： insistence, reference, recommendation, suggestion, proposal, motion, desire, requirement, request, order, necessity, regulation, rule, resolution, understanding
以上动词的同词根形容词及分词在that主语从句需用(should)+动词原形，如： advisable, desirable, insistent, referable, urgent, appropriate, compulsory, crucial, essential, imperative, important, natural, necessary, obligatory, possible, probable, proper, strange, vital, advised, arranged, commanded, demanded, desired, ordered, proposed, recommended, requested, required, suggested
举例：insist的用法
1. 表示“坚持说；坚决认为(多与别人的观点不同)”，接that从句(从句的动作为已发生之事)，从句使用陈述语气。
(1)She insisted that he was wrong. 她坚持认为他错了
(2)He insisted that he had done right. 他坚决认为自己做对了
2. 表示“坚决主张；坚持要求”，接that从句(从句的动作为将要发生之事)，谓语多为 should型的虚拟语气，即：主语+ should(可省略)+动词原形。如： He insisted that we (should) accept these gifts. 他一定要我们收下这些礼物。 Jane insisted that he be present. 简坚持要他出席。
区别主要还是在于"insist"在句中所表达的意思。
