1. 虚拟条件句

虚拟条件句，顾名思义，是在一个虚拟假想的条件下，来描述说话人想象的、非真实的情景，这些情景是不可能发生的，与客观事实相反的。我们可以将对现在、过去、将来这三种情况进行虚拟的情况进行分析。

1.l 对现在/一般事实进行虚拟

[例句] If I could rearrange the alphabet， I’d put U and I together.

[解析] 字母表排序是固定不变的，字母 U 和 I 不在一起，这里要表达与这一事实相反的情形，所以用虚拟语气。

[译文] 如果能重新把字母表排序，我一定会把 U 和 I 这两个字母放在一起。

[例句] I have often thought it would be a blessing if each human being were stricken blind and deaf for a few days at some time during his early adult life. Darkness would make him more apPciative of sight;Silence would teach him the joys of sound.

[解析] 这是 Helen Keller(1880～1968)一篇文章中的句子。表达一个与一般事实相反的假设情形。

[译文] 我常常想：如果每一个人在生活早期都要遭受几天眼睛失明、耳朵失聪，那可能是一种福气!黑暗会使他更加珍惜视觉;寂静无声能教会他欣赏声音的美妙。

1.2 对过去事实进行虚拟

真题再现

[例句] It would have been just as satisfactory if I had stayed at home. I learned nothing in class.
