Don't worry about little facts. Get the big idea first. If you see something you don't get, like a new word, put a pencil check in the margin next to it. Don't stop reading. Whatever you do, keep reading all the way to the end.
All writing starts with a main idea.
Write down the writer's main point on your paper. Don't go on until you get what they were trying to say. Look at the first sentence of every paragraph for clues. A writer often makes a statement, then uses the rest of the article to prove the point. Look at the headline or title of the article.
