Every year we're selling more than a ￡ 1, 000 million worth of cars abroad.

理解句子的关键是：谓语动词是sell，宾语是cars，而cars 之前的成分都是定语。句子的修饰关系分解如下：

We are selling good cars abroad.

We are selling 100 million cars abroad.

We are selling more than 100 million cars abroad.

We are selling a ￡ 1, 000 million worth of cars abroad.

We are selling more than a ￡ 1, 000 million worth of cars abroad.

红色部分都是定语。

问题中的句子，a worth of （某种价值的）。现在，我们把worth 具体化，之前加上具体的金额￡ 1, 000 million，让它作定语修饰worth：a ￡ 1, 000 million worth of

这类似a piece of news 和a good piece of news 的用法。
