高中英语必备知识点
虚拟条件句
条件状语从句是非真实情况，在这种情况下要用虚拟语气。
1.条件从句与现在事实不一致，句型为：If+主语十过去时，tiag+should (could，would，或might)+动词原形，例如：If l were you，1 would study hard.
2.条件从句与过去事实不一致，句型为：If+主语+had+过去分词，主语+should(could, would，或might)+have+过去分词，例如：If I had not studied hard.1would have failed in the exam last term
3.条件从句与将来事实不一致，句型为：lf+主语+should/were to+do，主语+should( could.)+原形do，例如：If l were to go to the moon one day,I could see itwith my own eyes.
注意：
1.If条件句中绝对不可出现“would”。
2.根据句中的时间状语，有时可能出现“混合虚拟”的情况，即主句可能是现在的情况，条件句也许是发生在过去的情况，但都遵守上述句型。
3.在条件句中如果出现were，had，should可省去if，将这些词提前置于句首构成倒装，例如：w.re I to go tothe moon one clay,1 would see it with my own eyes.如果有一天我登上月球，我就可以亲眼目睹它的样子了。

例如：Rice is planted in the south of China.
