对将来进行假设主要有三种情况:
1,if条件从句是谓语用动词过去式,则后面的主句是情态动词加动词原形
例:If I came tomorrow ,we would have the meeting.
2,if条件从句是were to形式,则后面的主句也是情态动词加动词原形
例:If it were to rain tomorrow ,the meting would be put off.
3,if条件从句是should do形式,则后面的主句可以用情态动词加动词原形,也可以用祈使句(但注意,祈使句仅适用于前面从句是should do形式的)
例:If it should rain tomorrow,don't expect me./I would not go there.

If I knew his telephone number,I would tell you.
如果我知道他的电话号码,我就会告诉你。(事实:不知道)
If there were no air or water,there would be no living things on the earth.
如果没有水和空气,地球上就不会有生物。(事实:地球上既有空气也有水)
If I had any money with me,I could lend you some.
如果我带钱了,我就会借给你些。(事实:没有带钱)
If he studied harder,he might pass the exam.
如果他再努力些,就能通过考试了。(事实:没有努力)
If I were you, I'd wear a shirt and tie.
如果我是你,我就会穿衬衫和领带。(事实:我并不是你)
2、表示与过去事实相反的情况
从句:If+主语+had+done
主句:主语+should/would/might/could+have done
eg:If I had got there earlier,I should/would have met her.
如果我早到那儿,我就会见到她。(事实:去晚了)
If he had taken my advice,he would not have made such a mistake.

将来的假设是基于当前信息和情况对未来可能发生的事件、趋势或情况进行推测和猜测。它可以涉及个人的未来计划,也可以是对整个社会、行业或全球的未来趋势的思考和预测。人们进行将来假设的目的是为了制定计划、做出决策以及预测可能的结果。
