A.Don't mention it B.Hm, not too bad C.Thanks D.Pretty fast 答案：B 二、阅读理解 Newspapers, along with reporting the news, educate, entertain, and give opinions. An important way of reading a large, big-city newspaper is to put it into different sections. Can you find these separate sections: world news, national and local news, sports, business, entertainment, opinions, ads? Does your paper have other sections? News stories give facts, not the reporter's opinions. Some newspaper editorials (社论) come out with the writer's name, but many newspapers only carry editorials without putting the writers' names on.
