I'd like to ask some questions regarding two sentences from the Murphy's grammar book.
1. Most of the earth's surface is covered by water.
Isn't it more common to use 'with' instead of 'by'?
2. If there are any unknown words that you don't know, use a dictionary.
Is it possible to use 'some' instead of 'any' in this example?
I'd be grateful for any comments.
I'm sorry, I didn't copy it correctly .
The original sentence reads
If you there are any words that you don't know, use a dictionary.
Yes, it is possible to use some there. Any sounds more natural to me, though.
Once it starts going wrong, it repeats. That's why I recommend not doing a rough draft and copying it up in an exam- it's very hard to spot mistakes like that.
