From paragraph 17 to 18. We can see that the author also used dashes in the sentences. Telling its own tale, these dashes mean explanation here. Also it can connect the sentence well. What is more, in paragraph 17 the word “triumph” puzzled me. So I look it up in the dictionary. The meaning is “a very great success, achievement or victory, or a feeling of great satisfaction or pleasure caused by this”. Then, in the paragraph 18, there is only a sentence in this paragraph. “Fortunately for everyone, I eventually --- it took me awhile---calmed down”. I am not familiar with the sentence after the comma. Especially, the sentence between two dashes attracts me. It is the fist time I have seen such a sentence as “it took me awhile”.Though it can be seen clearly from the whole sentence that [and]? its? the whole paragraph, then I get the meaning in my understanding---I eventually clamed down after a period of time. But I still confuse?[I am still confused]? by the word “It”. Followed by, I consult the book named <<Advance English Grammar>>. Here, the word “it” is unspecified it. And it can be anything in any situation. Now I will show you some sentences. It will take you a long time to do it. Take it easy. There is nothing else for it but to stand. Such instances can be quoted indefinitely, whereas these will suffice.
good job
your writing is better than me!---sunflower
