2 真实条件句主从句的时态问题

下面的4道习题要求处理好真实条件句中的动词形式问题:

1.      If she promised/ has promised (promise) to be here, she will certainly come.

2.      If he said (say) that, he must be a fool.

 

除了横线上的标准答案,请教老师能否使用promises 和says,表示“任何时候她一旦承诺,她就一定会来”以及“只要他说了,他就是傻子”?

 

3.If I was out of work, I did (do) some odd jobs.

4.  If you spent the night on the train, you probably need (need) a rest.

 

请教老师,第4可否像第3句的主句动词一样使用一般过去时,表示主从都是发生在过去的动作?

谢谢老师!

1.      If she promised/ has promised (promise) to be here, she will certainly come.

2.      If he said (say) that, he must be a fool.

以上二句中的指示副词here和指示代词that意味着这二个句子是事件意义,而不是习惯,因此不能用一般现在时,因为事件并没有在说话时发生。

3.If I was out of work, I did (do) some odd jobs.

该句为习惯意义,故主句可以用did或would do. would可以和动态动词连用表示过去的习惯。

4.  If you spent the night on the train, you probably need (need) a rest.

应该理解从句表示昨晚的事件,主句用一般现在是表示现在需要。

如果理解这个句子表示过去的习惯,那么现在这个习惯不存在了吗,现在乘火车就不需要休息了?不大符合逻辑。故应该按照事件意义理解。

没有特定的上下文,我觉得答案并不唯一。下面红色部分是我认为可能的答案:

1. If she has promised / promises to be here, she will certainly come.

2. If he says / has said that, he must be a fool.

3. If I was out of work, I did / would do some odd jobs.

4. If you spent the night on the train, you probably needed / would need a rest.
