Question

英语高手可以帮我看看这个句子的结构吗？从 in what 开始我就不懂了！！！高手指教啊！！

These are clearly the future opportunities and areas of growth in what is a total market worth an estimated 112 billion dollars。

Answer 1

These are clearly the future opportunities and areas of growth in what is a total market worth an estimated 112 billion dollars。

1. 先上一个类似的what从句，楼主先体会一下这个例句
They had arrived in what is now the northeastern United States a year earlier.
在前一年，他们到达了现在美国的东北部。
从例句中不难看出，what 指的就是后面的the northeastern United States
同理，所给题中的what 也就是后面的total market

2. a total market worth an estimated 112 billion dollars
worth(adj.) an estimated 112 billion dollars 作a total market 的后置定语,“预计能达到1120万美元的市场总价值”

3.what从句是一种特殊从句，我们可以将它看成宾语从句，也可以看成定语从句

但为了更好理解，我建议把它当成定语从句分析，这时what其实就是先行词和关系代词的综合，相当于the thing(s) that……或the person (people) that，于是所给题也就相当于以下这句：These are clearly the future opportunities and areas of growth in *the total market that* is
a total market worth an estimated 112 billion dollars。

这里表达了两层意思，【这些就是市场总价值中的未来增长机遇和增长点】，【市场总价值预计能达到1120万美元】，把它们整合起来就是一个定语从句了

4.很明显，这些就是/在/一个预计能达到1120万美元的市场总价值中的/未来增长机遇和增长点。
通顺点就是：
未来的市场价值总量预计能达到1120万美元，到那时，这些显然会成为新的增长机遇和增长点。

Answer 2

试试这样理解吧，what 就是一个从句中的一个“虚主语” 占着从句主语的位置使得从句不缺乏成分而构成一个完整的句子（因为从句也至少要有主语和谓语才能称之为“句”） 其实可以指代很抽象抑或很具体的名词

介词in+what引导的宾语从句组成一个介词短语做状语 表示这些是在 哪方面/哪里 是“机遇”是“增长点/增长领域”，就跟 I'll stay in a hotel, I'll stay in it 是一样的 只是前面这两句的介词in宾语只有一个名词hotel或者一个代词it 而原句中的in后面是一个完整的从句来做宾语 所以就是what引导宾语从句

what改成定语从句或者其他结构代替会比较清晰，先看一个简单的例子：

He will live in what is a quiet village for the rest of his life.
= He will live in some place that is a quiet village for the rest of his life.
= He will live in a village that is quiet for the rest of his life.
= He will live in a quiet village for the rest of his life.

然后再简化原句：

These are clearly the future opportunities and areas of growth
in what is a total market worth an estimated 112 billion dollars.
=in some place that is a total market worth an estimated 112 billion dollars.
=in a total market that is worth an estimated 112 billion dollars.
=in a total market worth an estimated 112 billion dollars.

谢谢您哦，也很详细，很难抉择选哪个好，不过很谢谢您的耐心，真的

Answer 3

在一个价值达到估计为1120亿美元的市场中，很显然，这些就是未来的机遇和增值领域。

what 是in的宾语，同时，也是宾语从句的主语。宾语从句：what is a total market worth an estimated 112 billion dollars

我还是不怎么明白，你能帮我把这句分成几个分句看吗？麻烦你了！！真的很谢谢！！

追答

In what 做主句的状语。暂且用in the place 代替，那就是这样：
主句 These are clearly the future opportunities and areas of growth in the place.
很显然，这些就是这个地方的未来的机遇和增值领域。

宾语从句The place is a total market worth an estimated 112 billion dollars.
这个地方是一个价值达到估计为1120亿美元的市场。

这是主句与状语中的名词性从句的关系，不是分句与分句的关系。
