问大全453

大全453。

It was the loss of revenue from declines in tourism that in 1935 led the Saudi authorities' granting a concession for oil exploration to the company that would later be known by the name of Armco.

(D)authorities to grant a concession for oil exploration to the company that later will be known as being

(E)authorities to grant a concession for oil exploration to the company later to be known as

我觉得E的结构不完整阿，为什么答案是它？

不好意思，我没有找到对这道题以前的讨论，所以看个新帖啦。谢谢各位！！！

是没找到。

It（主语） was（谓语）the loss of revenue from declines in tourism(实际主语） that in 1935（时间状语）led（实际谓语） the Saudi authorities to grant a concession for oil exploration to the company later to be known as Armco.

好象什么都不缺啊

我主要不明白 “later to be known as”, 那是用不定式做company的定语吗？或者是中间省略了什么？

对。the company later to be known as Armco.=

the company which was known as Armco later.看来当时公司不叫这个名字

Can we change the choice E in this way: authorities to grant a concession for oil exploration to the company later known as?

"later to be known as" makes me feel very uncomfortable. It sounds like that the action "known" has not happened by the point of time when the sentence in question is mentioned. "to be known as" seems not compatible with the past tense of the whole sentence.

对于不定式表达时态，我们可以看这样一个例子：

I want to do sth. 表达的是现在want将来(to do)做sth。want表示现在，而to do表示从现在开始的将来。但是如果句子改为：I wanted to do sth. 句中wanted表示过去，而to do显然是表达了从wanted这个过去时间开始的将来，而这个将来对于现在来说，可能已经发生了，也可能正在发生，当然也可能还没有发生。同理，这道题也可以通过这个思路来理解。

嗯，我明白了！谢谢！

受stoneren启发，我终于知道这道题之所以会让我觉得迷惑，是因为句子采用了省略结构：the company (that was) later to be known as。表示过去时的that was被省略掉了，只剩下to be known，所以我就对这句话里to be known表示的时态迷糊了。

可是我觉得I wanted to do sth和这句话还是有区别的。

I wanted to do sth,用 to do 表示将来do sth.

the company later to be known as 中，later已经表示了known是将来的事，为什么还要用to be 呢？而且如果去掉later,变成: the company later known as,有区别吗？

还有，原句中later应该修饰的是to be，而不是later known,为什么是later to be 呢？
