How to Do Reading
In my opinion, when it comes to reading English articles, I think it's necessary to look through all paragraphs, so that we can get the main ideas of the article.
If you don't have enough time to go through it, then just get the main idea of each paragraph. Basically, there would be a hint at the beginning of the article, which will tell us what this article is all about. And in the following paragraphs, the key idea usually exists in the beginning or at the end of the paragraph. Then, run to the conclusion part to get the writer's opinion on this.
