Millions of British families were in for a very difficult time in the months ahead.

【分析】

1. in the months ahead：在未来的那些月中

2. be in for 意思是“处在某种状态”，“免不了遭受”。其中in 是副词，for 是介词。又如：

If it is not stronger this year, we are in for a very difficult 2010 as well.

如果今年形势没有好转，我们就意味着要迎接一个同样困难的2010年。

You will be in for trouble when they find out who broke the window.

如果他们发现是谁打破了窗户，你肯定会有麻烦。

You'll be in for trouble if you don't take my advice.

如果不听我的劝告，你非遇到麻烦不可。

We could say that the match with the Faroe Islands can be considered a good training session in view of our trip to Lithuania, where we will be in for a very difficult time.

和打立陶宛相比，我们可以把客场征战法罗群岛的比赛看作是一堂训练课，但是与立陶宛的交锋会非常的艰苦。
