大雨使我们不能按时完成我们的工作。

(1) Way （意为“方法”） 经常不用介词。 例如：
I think you’re putting it together in the wrong way.我认为你把它装错了。
Do it any way you like. 你爱怎么干就怎么干。
注意： 在有关从句的句子里，我们在way后面常用that 来代替in which。 例如：

（3）不要混淆in the way 和on the way： in the way是用来谈障碍-----阻止你到想到去的地方的人或物：on the way意为“在途中”。试比较：
Please don’t stand in the kitchen door, you’re in the way.
Let’s not stop too often on the way.

(2) used to do sth 过去经常做什么
