Hi Maryuris. Your sentences look good. The only correction that I have is to add a comma between 'shower' and 'and' in the second sentence. Or you could write that sentence like this: Then, I take a shower and get dressed. Because I is the subject for both clauses, you can remove the second I and omit the comma.

I went to Kagoshima in southeast Kyushu. Kagoshima has many mountains. One of the most famous mountains is Sakura Island, a volcano that still erupts. I was surprised that Sakura island had erupted more than 150 times during that year. While there I found that the rocks on this island are black. I think it is lava.

Hi, When 'as' and 'since' are used as subordinating conjunctions to introduce a reason, they have the same meaning and are interchangeable. Here is a link to some examples: http://dictionary.cambridge.org/us/grammar/british-grammar/as-because-or-since Kind Regards, Cynthia

Hi Davood, When people say 'Did you ever...' it would be followed by 'go' instead of 'be' if asking if the person went there. Did you ever go to New York? Yes, I went there twice. I think that 'Have you ever been' is more common when asking if someone has been to a place, but I have heard people use 'Did you ever..'. I suppose it depends on the person's dialect. Also, sometimes 'Did you ever...' doesn't mean the same thing as 'Have you ever...' Sometimes 'ever' is just used for emphasis. For example: Bob has been talking about a business trip that was delayed. His friend, James, wonders if he went or not. James: "Hey Bob, did you ever go to New York?" Bob: "Yes, I finally went. I just got back yesterday." I hope this helps. Have a great day! Kind Regards, Cynthia

Hi Hommayra, "Mutual boundary determination of A with B' might sound better like this: Mutual boundary determination between A and B... Or you could use: 'agreement on the location of the border between A and B...' It's hard to say without seeing the rest of the sentence. If you post the entire sentence that you want to write with that noun phrase, I'll have a better idea of ways to rephrase it. I hope this helps. Have a great day! Kind Regards Cynthia

Hi, Here's how the sentence should read. A modern city has been set up in what was a wasteland ten years ago. Now I'll try to explain why, and I hope I'm right :) If anyone sees a mistake here, please chime in. I think that 'what' is a relative pronoun that begins the noun clause '...what was a wasteland...'. This noun clause is the object of the prepositional phrase 'in what was a wasteland' which functions as an adverb telling where the city was setup. I hope this helps. Have a great day! Kind Regards, Cynthia
