虛擬語氣應(yīng)該注意的幾點:
1.虛擬語氣在條件句中
1)表示不太可能出現(xiàn)的情況”, 條件從句一般用過去時,主句用would do, should do 或 might /could do;
2)表示“本可能發(fā)生卻未發(fā)生的事情”， 條件從句用過去完成時，主句用would have done, should have done, might / could have done
the old men would find it difficult to get a job if they left the farm.
i should be surprised if it was less than five pounds.
if i frightened those birds, they might fly off and i would never see them again.
if i were you, i would accept the offer.
if i were asked to define my mood, i’d say “bored”.
if he had taken his doctor’s advice, he might not have died so soon.
if he had realized that, he would have run away while there was still time.
if she had not married, she could have become special in the filed.
2.虛擬語氣在條件句也可用來表示“將來不太可能出現(xiàn)的情況”， 條件從句用 should do, were to 或一般過去時，主句用 would do, should do, could/might do.
if it should rain tomorrow, the sports meet would have to be put off.
i could see the surface of the moon with my own eyes if i were to go to the moon some day.
what would you do if he failed to come tomorrow?
注意：含有 should 的條件句，主句可以用一般現(xiàn)在時或一般將來時.例如：
if there should be another flood, what shall we do?

3. 在正式英語文體中，if 從句中的第一個動詞如果是should, were 或 had, 可將此動詞置于句首，替代 if.例如：
were it all true, it would still not excuse their actions.
