Daniel: one night,when I was sleeping in the bed,I felt that someone was knocking outside the window.
Correct: One night, when I was sleeping on my bed, I felt like I heard someone knocking on the window.
Explanation: I am not sure if you mean?if there was literally someone knocking on the window. Or if you mean to say that you heard from the window that someone was knocking. These are two different things. Be particular with how the action was done. Also, I replaced the "in" to "on" because you were physically ON the surface of the bed at that moment and not INSIDE it. Lastly, please capitalize the first word?of your sentence; know proper spacing and put correct punctuation marks.

Daniel:?but it was a tree that it was fallen by a typhoon.
Correct: But it was just a fallen tree strongly hit by the typhoon.
Explanation: Again,?capitalize the first word of your sentence. This one?doesn't actually sound bad but I put additional words to specify things. I put "just" because at that moment you discovered that it was "just" a tree. Secondly, it was a fallen tree and the thing that caused the damage was the typhoon. Third, I replaced your "a" into "the" because we're talking about specific things here. Please know the proper usage of articles.

Daniel:?Next morning, the construction cars came and removed the tree.
Correct: The next morning, a construction team came and they took away the tree.
Explanation: Your sentence is not totally wrong. I added the article "the" to specify things. We rarely use the term "construction cars." There's no such thing as that especially if we're referring to a group of people so it should be "construction team." Lastly, your usage of the word "remove" is fine but the term "take away" is better.

Final Note: Please be particular with punctuation marks, capitalization and spacing. Be specific when your describe events and things. It should be fully detailed. Last, try to prolong your paragraph next time. It doesn't need to be very long but you need to include details to put your thoughts across properly.

Thank you for giving enough time and effort submitting your homework. I really appreciate this, Daniel. See you!
