单选题{{B}}Passage 4{{/B}} The fossil remains of the first flying vertebrates, the pterosaurs. have intrigued paleontologists for more than two centuries, How such large creatures, which weighed in some eases as much as a piloted hang-glider and had wingspans from 8 to 12 meters, solved the problems of powered flight, and exactly what these creatures were — reptiles or birds — are among the questions scientists have puzzled over. Perhaps the least controversial assertion about the pterosaurs is that they were reptiles. Their skulls, pelvises, and hind feet are reptilian. The anatomy of their wings suggests that they did not evolve into the class of birds. In pterosaurs a greatly elongated fourth finger of each forelimb supported a wing like membrane. The other fingers were short and reptilian, with sharp claws. In birds the second finger is the principal strut of the wing, which consists primarily of feathers. If the pterosaurs walked on ail fours, the three short fingers may have been employed for grasping. When a pterosaur walked or remained stationary, the fourth finger. and with it the wing, could only turn upward in an extended inverted V-shape along each side of the animal's body. The pterosaurs resembled both birds and hats in their overall structure and proportions. This is not surprising because the design of any flying vertebrate is subject to aerodynamic constraints. Both the pterosaurs and the birds have hollow bones, a feature that represents a savings in weight. In the birds, however, these bones are reinforced more massively by internal struts. Although scales typically cover reptiles, the pterosaurs probably had hairy coats. T.H. Huxley reasoned that flying vertebrates must have been warm-blooded because flying implies a high rate of metabolism, which in turn implies a high internal temperature. Huxley speculated that a coat of hair would insulate against loss of body heat and might streamline the body to reduce drag in flight. The recent discovery of a pterosaur specimen covered in long, dense, and relatively thick hair—like fossil material was the first clear evidence that his reasoning was correct. Efforts to explain how the pterosaurs became airborne have led to suggestions that they launched them- selves by jumping from cliffs, by dropping from trees or even by rising into light winds from the surfaces of waves Each hypothesis has its difficulties. The first wrongly assumes that the pterosaurs' hind feet resembled a hat's and could serve as hooks by which the animal could hang in preparation for flight. The second hypothesis seems unlikely because large pterosaurs could not have landed in trees without damaging their wings. The third calls for high waves to channel updrafts. The wind that made such waves however, might have been too strong for the pterosaurs to control their flight once airborne.

单选题{{B}}Text 4{{/B}} Most people are familiar with comic books and comic strips. The comic strip is usually found in daily newspapers. It is made up of three or four picture panels telling a story with one or more characters. Some comic strips tell a different incident every day. In other comic strips the story continues from day to day until it is finished, and then a new story begins with the same main characters. Comic books are extensions of comic strips into magazines. Each magazine is about one set of characters, and the pictures tell a complete story. Generally comic books are printed in color. The words are prined in balloons over a speaker's head to indicate the person speaking. A few sentences may be used to bridge a gap in a story, but most of the plot is carried by direct conversation and by action in the pictures. Comic book covers are made of glossy paper, and there are generally the same number of pages- usually 32 - in each book in a particular series. More than one story is included in each issue, and there is usually some advertising. Comic books are published regularly, that is to say, every month, every 2 months, or once a year. Because of their regular publication, they are often called comic magazines. Approximately 200 different titles are published. The exact number varies from month to month. Some people estimate that close to 500,000,000 copies of comic books are sold each year. Comic strips are not all-humorous stories. The Comics Magazine Association of American lists these types of comic books: adventure, animal, biography, detective, fantasy, mystery, history, humor, military, religion, romance, satire, science-fiction, teenage, "kiddie", and western. Some types, such as adventure and humor, sell better, so there are more of them. However, the popularity of comic books has led many kinds of groups to use them to tell a story. There are comic strips in some Sunday school papers, the army uses the comic-strip technique in training soldiers, and many companies use comic books to tell their story behind a product or the history of their company. Comic strips began in newspapers as early as the 1870's. Comic books similar to those published today first appeared in the 1930's and were collections of comic strips previously printed. The next step in comic book history was the writing of stories for comic book use alone, using a single set of characters in two or three plots. The development of animated cartoon movies led to comic books about the same characters, such as Mickey Mouse. Sometimes a comic book retells a plot from a movie or a popular old book, in at least one case-Superman-the comic strip and comic book character led to television and movie versions. Television shows that are popular with young people are often made the subject of comic books because the publishers know they will quickly find buyers. The comic-book form is sometimes used to teach as well as entertain. Comic books are used to help explain complicated subjects. They are also useful tools to civil organizations in public information campaigns. A reference list of free and inexpensive materials will include many comic books such as those published by General Electric, Goodrich Company, or Swift and Company. Such material often contains valuable information. However, it is wise to keep in mind the source of the material if it is to be used in arguments. For instance, material from the American Railway Association will not tell about similar services performed by the national trucking industry. Telling a story through pictures will probably continue to be popular for some time to come. However, comic books have changed a great deal since they first began. Other changes will very likely come in the future.

单选题{{B}}Passage 4{{/B}} The importance and focus of the interview in the work of the print and broadcast journalist is reflected in several books that have been written on the topic. Most of these books, as well as several chapters, mainly in, but not limited to, journalism and broadcasting handbooks and reporting texts, stress the "how to" aspects of journalistic interviewing rather than the, conceptual aspects of the interview, its context, and, implications. Much of the "how to" material is based on personal experiences and general impressions. As we know, in journalism as in other fields, much can be learned from the systematic study of professional practice. Such study brings together evidence from which broad generalized principles can be developed. There is, as has been suggested, a growing body of research literature in journalism and broadcasting, but very little significant attention has been devoted to the study of the interview itself. On the other hand, many general texts as well as numerous research articles on interviewing in fields other than journalism have been written. Many of these books and articles present the theoretical and empirical aspects of the interview as well as the training of the interviewers. Unhappily, this plentiful general literature about interviewing pays little attention to the journalistic interview. The fact that the general literature on interviewing does not deal with the journalistic interview seems to be surprising for two reasons. First, it seems likely that most people in modern Western societies are more familiar, at least in a positive manner, with journalistic interviewing than with any other form of interviewing. Most of us are probably somewhat familiar with the clinical interview, such as that conducted by physicians and psychologists. In these situations the professional person or interviewer is interested in getting information necessary for the diagnosis and treatment of the person seeking help. Another familiar situation is the job interview. However, very few of us have actually been interviewed personally by the mass media, particularly by television. And yet, we have a vivid acquaintance with the journalistic interview by virtue of our roles as readers, listeners, and viewers. Even so, true understanding of the journalistic interview, especially television interviews, requires thoughtful analysis and even study, as this book indicates.
