2014年6月大学英语四级考试真题及答案完整版(4)

Questions 36 to 45 are based on the following passage.

Global warming is a trend toward warmer conditions around the world. Part of the warming is natural; we have experienced a 20,000 -year -long warming as the last ice age ended and the ice 36 away. However, we have already reached temperatures that are in 37 with other minimum-ice periods, so continued warming is likely not natural. We are 38 to a predicted worldwide increase in temperatures 39 between 1℃ and 6℃ over the next 100 years. The warming will be more 40 in some areas, less in others, and some places may even cool off. Likewise, the 41 of this warming will be very different depending on where you are—coastal areas must worry about rising sea levels, while Siberia and northern Canada may become more habitable (宜居的) and 42 for humans than these areas are now.

The fact remains, however, that it will likely get warmer, on 43 , everywhere. Scientists are in general agreement that the warmer conditions we have been experiencing are at least in part the result of a human-induced global warming trend. Some scientists 44 that the changes we are seeing fall within the range of random (无规律的) variation—some years are cold, others warm, and we have just had an unremarkable string of warm years 45 —but that is becoming an increasingly rare interpretation in the face of continued and increasing warm conditions.

Directions: In this section, you are going to read a passage with ten statements attached to it. Each statement contains information given in one of the paragraphs Identify the paragraph from which the information is derived. You may choose a paragraph more than once. Each paragraph is marked with a letter. Answer the questions by marking the corresponding letter on Answer Sheet 2.

The End of the Book?

[A] Amazon, by far the largest bookseller in the country, reported on May 19 that it is now selling more books in its electronic Kindle format than in the old paper-and-ink format. That is remarkable, considering that the Kindle has only been around for four years. E-books now account for 14 percent of all book sales in the country and are increasing far faster than overall book sales. E-book sales are up 146 percent over last year, while hardback sales increased 6 percent and paperbacks decreased 8 percent.

[B] Does this spell the doom of the physical book? Certainly not immediately, and perhaps not at all. What it does mean is that the book business will go through a transformation in the next decade or so more profound than any it has seen since Gutenberg introduced printing from moveable type in the 1450s.

[C] Physical books will surely become much rarer in the marketplace. Mass market paperbacks, which have been declining for years anyway, will probably disappear, as will hardbacks for mysteries, thrillers, “romance fiction,” etc. Such books, which only rarely end up in permanent collections, either private or public, will probably only be available as e-books within a few years. Hardback and trade paperbacks for “serious” nonfiction and fiction will surely last longer. Perhaps it will become the mark of an author to reckon with that he or she is still published in hard copy.
