问题描述：
it is most desirable that he -- for the information by himself with a few clicks online
A search B searched C has searched D will search
A 为什么?不是虚拟语气吗
答
楼主你是正确的,这里就是要用虚拟语气,因此原句是：It is most desirable that he [should] search for the information by himself...而因为这个should能够省,省了之后就变成了仿佛第三人称主语直接加原型的假象了....
