 Re: adverbial clause
Hi Jiang,
It might be easier to understand the difference in sentences formed like this:
We went along a dirt road that led down into the valley where there was a pond
We went along a dirt road that led down into a valley, where there was a pond.
The second sentence (as the sentence in your example) involves a place adverbial. The first sentece involves a wh-clause with the function of post-modifier of "valley" |
