suggest引导的从句为什么要用虚拟语气

不是都要用虚拟啊!1。若suggest 表示“建议”,则其后接的 that 从句谓语通常用“(should)+动词原形”这样的虚拟语气形式。如：I suggested that she should go home。我建议她回家去。She suggested that I (should) be the leader。她提议由我来做领导人。2。若suggest 表示“暗示“”“意指”“表明”等义,则其后接的 that 从句要用陈述语气。如：What he said suggested that he was a cheat。他说的话表明他是个骗子。Are you suggesting that I’m not suited for the job?你的意思是说我不适合做这工作?
