单选题{{B}}Text 2{{/B}} Comics in America have broadened their appeal by marketing to adults. Prior to World War II , usually only adolescents bought comics. During World War I1, the comic book industry in the United States began to undergo a major change. When the war started, the government subsidized the comics industry in order to take advantage of the powerful propaganda effects, regulating them for purposes of military defense. By the time the war was over, the taste for comic books had reached the adult population. Publishers from this point on expanded this portion of the market that was to become the largest sales increase in the history of the comic industry. The editor of Exciting Comics, Ed O' Donnell, was important in extending the success of this marketing drive. Here organized comic drawing to encourage artists' innovation. The market had declined slightly since the late forties. O' Donnell, against conventions, hired adroit illustrators. He abandoned the low-cost budget publication, a step considered risky to his peers in the publication industry; however, his begin environment for artistic creation eventually proved successful. Kenny Bar was one of the artists that helped spawn the most innovative titles to come out of Exciting Comics. He insisted on revising the concept of the comic book radically; he proposed to create characters designed to capture markets that had previously not been successfully explored by comic books. This revolutionary idea laid the foundation for the now thriving market for sophisticated adult-oriented comic books.

单选题Engineering students are supposed to be examples of practicality and rationality, but when it comes to my college education I am an idealist and a fool. In high school I wanted to be an electrical engineer and, of course, any sensible student with my aims would have chosen a college with a large engineering department, famous reputation and lots of good labs and research equipments. But that's not what I did. I chose to study engineering at a small liberal-arts (文科) university that doesn't even offer a major in electrical engineering. Obviously, this was not a practical choice; I came here for more noble reasons. I wanted a broad education that would provide me with flexibility and a value sys- tem to guide me in my career. I wanted to open my eyes and expand my vision by interacting with people who weren't studying science or engineering. My parents, teachers and other adults praised me for such a sensible choice. They told me I was wise and mature beyond my 18 years, and I believed them. I headed off to college sure I was going to have an advantage over those students who went to big engineering" factories" where they didn't care if you had values or were flexible. I was going to be a complete engineer: technical genius and sensitive humanist (人文学者) all in one. Now I'm not so sure. Somewhere along the way my noble ideals crashed into reality, as all noble ideals eventually do. After three years of struggling to balance maths, physics and engineering courses with liberal-arts courses, I have learned there are reasons why few engineering students try to reconcile (协调) engineering with liberal-arts courses in college. The reality that has blocked my path to become the typical successful student is that engineering and the liberal arts simply don't mix as easily as I assumed in high school. Individually they shape a person in very different ways; together they threaten to confuse. The struggle to reconcile the two fields of study is difficult.

单选题 My family and I recently returned from a trip to Alaska, a place that combines supernatural beauty with a breathtaking amount of bear risks. I'll start with some facts at a glance: WHERE ALASKA IS: Way the hell far from you. Beyond Mars. HOW YOU GET THERE: You sit in a variety of airplanes for most of your adult life. WHAT THEY HAVE THERE THAT WILL TRY TO KILL YOU: Bears. I am quite serious about this. Although Alaska is now an official state in the United States with modern conveniences such as rental cars and frozen yogurt, it also allows a large number of admitted bears to stride freely, and nobody seems to be the least bit alarmed about this. In fact, the Alaskans seem to be proud of it. You walk into a hotel or department store, and the first thing you see is a glass case containing a stuffed bear the size of a real one. Our hotel had two of these. It was what we travel writers call "a two-bear hotel". Both bears were standing on their hind legs and striking a pose that said: "Welcome to Alaska! I'm going to tear your arms off!" This struck me as an odd concept, greeting visitors with a showcase containing a major local hazard. It's as if an anti-drug organization went around setting up glass display cases containing stuffed drug smugglers(走私者), with little plaques(胸章)stating how much they weighed and where they were taken. Anyway, we decided the best way to deal with our fear of bears was to become well informed about them, so we bought a book, Alaska Bear Tales. Here are some of the chapter titles, which I am not making up: "They'll Attack Without Warning" "They'll Really Attack You" "They Will Kill" "Come Quick! I'm Being Eaten by a Bear!" "They Can Be Funny" Ha-ha! I bet they can. I bet Mr. and Mrs. Bear will fight playfully over the remaining portion of a former tourist plumped up by airline food. But just the same, I'm glad that the only actual bears that we saw were in the zoo.
