By reading the article, I learned that, sometimes, we may write the quotation at the beginning of the paragraph or the end of the paragraph. When that happens, the article may make people feel like this is a “semi-finished product”. So the reader got uncomfortable, even you have revolutionarily language, they may ignore them still. The way that how to fix the issue was mention in the article: “in the majority of situations, readers appreciate being guided to and led away from a quotation by the writer doing the quoting. Readers get a sense of pleasure from the safe flow of hearing how to read an upcoming quotation, reading it, and then being told one way to interpret it. Prepare, quote, analyze.” I agree that and that is a good way in fact. I mean if you don’t add some guide, the reader may think something about your writing way, and completely deviate from what you want to convey to the reader, even the opposite effect. So this is particularly important. We can’t make the reader feel at a loss.

The quotable I used in unit 2 is “‘Animals can become a way of building a bridge for those social interactions,’Griffin says. He adds that researchers are trying to better understand these effects and who they might help.” This suggests that animals do have positive effects on mental territories and social spacing. The researchers are still trying to refine the differentiation, such as how to target a particular key population. So that means you can keep pets if you are struggling with some hard situation.  You can ask for professional advice about your situation. Maybe a dog makes you dynamic, a cat makes you feel the company, a fish makes you feel relax. Pets can reduce your stress, eliminate your bad mood, or break the “wall” of your kid with society. And their ability is much more than that. So these answers about why and how may eliminate your doubting and concern.
