Correct, Bizheng. Don’t forget to review the Essay Outline in the same Unit 1 which clearly tells you the Comparison and Contrast strategies such as Maxi-Blocking (shorter paragraphs-one for comparison and the next one for the contrast), or the so-called Mini-Blocking (longer paragraphs but each sentence is construed of both comparisons and contrast, using words such as “although, however, similar to, etc…” For example, here is the C & C Thesis Sample, which I used in the Essay Lesson. Please pay attention to the aforementioned C&C transitional words: “Although Clementine wanted to ‘brain-erase’ Joel due to her innate impetuousness and restlessness to move on with her life and perhaps seek out another lover, Joel, on the other hand, agreed to ‘brain-erase’ Clementine not because he did not love her anymore, but because he was sincerely hurt by her; yet ultimately, he did not want to erase her, because it was that very restlessness and impetuousness of hers that meant to him, an absolute freedom from his usual, ordinary and unexciting self.”
