在英语四级备考过程中，虚拟语气是一个重要的考点，尤其是名词性从句中的虚拟语气。本文将详细讲解在suggest/insist等动词后宾语从句中使用(should)+动词原形的规则，并通过30例真题虚拟句分析帮助考生更好地掌握这一语法点。
一、虚拟语气的基本概念
虚拟语气是指在某些特定情况下，动词的形式不表示真实的情况，而是表示一种假设、建议、命令或愿望。在名词性从句中，虚拟语气常用于表示建议、命令或要求。
二、suggest/insist等动词后的宾语从句虚拟
在英语中，当suggest、insist、demand、require等动词表示建议、命令或要求时，其后的宾语从句需要使用虚拟语气，即(should)+动词原形。需要注意的是，should在很多情况下可以省略。
1. suggest后的宾语从句
当suggest表示“建议”时，其后的宾语从句应使用虚拟语气。例如：
- He suggested that we (should) start early.
- The doctor suggested that she (should) take more rest.
2. insist后的宾语从句
当insist表示“坚持要求”时，其后的宾语从句也应使用虚拟语气。例如：
- She insisted that he (should) apologize.
- He insisted that the meeting (should) be postponed.
