To begin, for me, after doing exercises which were given above I realized that there are still a lot that I need to learn more about parts of speech, especially adjectives and adverbs. For instance, new things that I learned "not, so, and etc.. can be function as adverb. Since I have studied these lessons once for the past three years, I thought these were easy and simple to me. Actually, it was not as simple as I thought. But I am happy, for I can realize like this.
