什 么 是 虚 拟 语 气？
虚拟语气
Ｉ.概念: 虚拟语气是动词的一种特殊形式，用来表示 所说的话不是事实，或者是不可能发生或可 能性很小的情况，而是一种愿望，建议，假 设的语气叫虚拟语气。
II.英语动词有三种语气 陈述语气,祈使语气和虚拟语气.

动词过去式 did （be用were）
主句
would (should, could, might)＋动词原形

( B )1. _______he come , the problem would be settled. A Would B Should C. Shall D. If
(C

• 2.含蓄条件虚拟句 • 句中含有with, without, but for, or, otherwise,
or else等，虽然没有出现if，但表示的是if的含义。 • (1) Without your help, I w_o_u_l_d_n_’__t__h_a_v_e__p_a_s_sed
(D )1.If you _________ the doctor’s advice, you would have recognized already. A. followed B would follow C follow D had followed
