英语动词有三种不同语气:陈述语气(indicativemood)、祈使语气(imperative mood)、虚拟语气(subiunctive mood)。所谓虚拟语气是指说话人为表示一种假设的情况、一种主观的愿望,即认为动词所表示的动作或状态并非事实或仅是主观设想时所用的动词形式。虚拟语气是一个大杂烩,它既包括假设语气、条件语气,也包括可能语气和愿望语气。 English verbs have three different moods: indicative mood, imperative mood, and subiunctive mood. The so-called virtual tone refers to a situation in which the speaker expresses a hypothesis and a subjective desire, that is, the action or state represented by the verb is not a fact or is only a verb form used in the subjective assumption. The subjunctive mood is a hodgepodge that includes both hypothetical tone and conditional tone as well as possible tone and wish tone.
