Europa is the smallest of planet Jupiter’s four largest moons and the second moon out from Jupiter. Until 1979, it was just another astronomy textbook statistiC.Then came the close-up images obtained by the exploratory spacecraft Voyager 2, and within days, Europa was transformed—in our perception, at least—into one of the solar system’s most intriguing worlds. The biggest initial surprise was the almost total lack of detail, especially from far away. Even at close range, the only visible features are thin, kinked brown lines resembling cracks in an eggshell. And this analogy is not far off the mark.The surface of Europa is almost pure water ice, but a nearly complete absence of craters indicates that Europa’s surface ice resembles Earth’s Antarctic ice cap. The eggshell analogy may be quite accurate since the ice could be as little as a few kilometers thick—a true shell around what is likely a subsurface liquid ocean that, in turn, encases a rocky core. The interior of Europa has been kept warm over the eons by tidal forces generated by the varying gravitational tugs of the other big moons as they wheel around Jupiter. The tides on Europa pull and relax in an endless cycle. The resulting internal heat keeps what would otherwise be ice melted almost to the surface. The crack like marks on Europa’s icy face appears to be fractures where water or slush oozes from below.Soon after Voyager 2’s encounter with Jupiter in 1979, when the best images of Europa were obtained, researchers advanced the startling idea that Europa’s subsurface ocean might harbor life. Life processes could have begun when Jupiter was releasing a vast store of internal heat. Jupiter's early heat was produced by the compression of the material forming the giant planet. Just as the Sun is far less radiant today than the primal Sun, so the internal heat generated by Jupiter is minor compared to its former intensity. During this warm phase, some 4.6 billion years ago, Europa’s ocean may have been liquid right to the surface, making it a crucible for life.1. What does the passage mainly discuss?2. It can be inferred from the passage that astronomy textbooks prior to 1979 _____.3. It can be inferred from the passage that Europa and Antarctica have in common which of the following?4. According to the passage, what is the effect of Jupiter's other large moons on Europa?5. According to the passage, Voyager 2’s images led researchers to develop which of the following theories?

The term “print” has several meanings, so it is important to understand exactly what is meant by the artistic terminology. A print in the artistic sense is not a reproduction of a work of art done in some other medium, such as painting or drawing. That can in no sense be considered a work of art, since the artist had no involvement with it. A print is an original work of art created by an indirect methoD.Instead of making an image directly on a surface, as in drawing or painting, the artist works on a master surface, which may be a sheet of metal, a block of stone, wood, plastic, or linoleum. From this master surface, numerous impressions may be made by inking the surface, laying a sheet of paper on it, and then subjecting both surface and paper to pressure, generally by means of a printing press.A print may exist in several versions. Sometimes the printmaker alters the image between impressions, so that each print is slightly different from the others. Any series of such prints is referred to as multiples. The number of impressions (known as the edition) that are possible from a single original varies with the material. Prints made from linoleum, which wears readily, will be fewer than those made from a metal plate, which is capable of striking fine-quality prints in the thousands. It is customary to number prints as they come off the press, the earlier impressions being the finest and therefore the most desirable.Prints incorporate the same compositional principles, as paintings. Line, shape, or texture may be the predominant element according to the printing technique useD.Some prints have obvious decorative qualities while others may be filled with emotional impact.Printmaking derives from two historical sources: early woodblocks into which an image was cut and used to illustrate a book or playing cards, and the medieval practice of decorating metal with incised designs, as in armor. Today most techniques fall into one of four categories: relief, intaglio, lithography, and serigraphy. However, there are many variations, combinations with photographic techniques, and considerable overlapping.1. In the artistic sense, a print is a work of art created by _.2. Which of the following is mentioned as an example of a master surface?3. It can be inferred that prints may differ from other works of art in terms of all of the following EXCEPT_.4. A metal plate is compared favorably with linoleum as a meter surface because a metal plate _.5. It can be inferred that prints may differ from other works of art in terms of all of the following EXCEPT _.

The French word renaissance means rebirth. It was first used in 1855 by the historian Jules Michelet in his History of France, then adopted by historians of culture, by art historians, and eventually by music historians, all of whom applied it to European culture during the 150 years spanning 1450-1600. The concept of rebirth was appropriate to this period of European history because of the renewed interest in ancient Greek and Roman culture that began in Italy and then spread throughout Europe. Scholars and artists of the fifteenth and sixteenth centuries wanted to restore the learning and ideals of the classical civilizations of Greece and Rome. To these scholars this meant a return to human as opposed to spiritual-values. Fulfillment in life—as opposed to concern about an afterlife—became a desirable goal, and expressing the entire range of human emotions and enjoying the pleasures of the senses were no longer frowned on.Artists and writers now turned to secular as well as religious subject matter and sought to make their works understandable and appealing. These changes in outlook deeply affected the musical culture of the Renaissance period—how people thought about music as well as the way music was composed, experienced, discussed, and disseminateD.They could see the architectural monuments, sculptures, plays, and poems that were being rediscovered, but they could not actually hear ancient music—although they could read the writings of classical philosophers, poets, essayists, and music theorists that were becoming available in translation. They learned about the power of ancient music to move the listener and wondered why modern music did not have the same effect. For example, the influential religious leader Bernardino Cirillo expressed disappointment with the learned music of his time. He urged musicians to follow the example of the sculptors, painters, architects, and scholars who had rediscovered ancient art and literature.The musical Renaissance in Europe was more a general cultural movement and state of mind than a specific set of musical techniques. Furthermore, music changed so rapidly during this century and a half-though at different rates in different countries—that we cannot define a single Renaissance style.1. What is the passage mainly about?2. What does the author mean by using the word eventually in Para.1?3. It can be inferred from the passage that thinkers of the Renaissance were seeking a rebirth of _.4. According to the passage, Renaissance artists and writers had all of the following intentions EXCEPT _.5. Which of the following is mentioned in the passage as a reason for the absence of a single Renaissance musical style?

McDonald’s, Greggs, KFC and Subway are today named as the most littered brands in England as Keep Britain Tidy called on fast-food companies to do more to tackle customers who drop their wrappers and drinks cartons (盒子)in the streets.Phil Barton, chief executive of Keep Britain Tidy, 1 its new Dirty Pig campaign, said it was the first time it had investigated which brands made up “littered England” and the same names appeared again and again. “We condemn people for dropping this fast food litter in the first place but also believe the results have 2 messages for the fast food industry. McDonald’s, Greggs, KFC and Subway need to do more to 3 littering by their customers.”He recognized efforts made by McDonald’s, including placing litter bins and increasing litter patrols, but its litter 4 “all too prevalent”. All fast food chains should reduce unnecessary packaging, he addeD.Companies could also reduce prices for those who stayed to eat food on their premises, offer money-off vouchers or other 5 for those who returned packaging and put more bins at 6 points in local streets, not just outside their premises. A spokesman for McDonald’s said: “We do our best. Obviously we ask all our customers to 7 of litter responsibly.” Trials of more extensive, all-day litter patrols were under 8 in Manchester and Birmingham. KFC said it took its 9 for litter management “very seriously”, and would introduce a program to reduce packaging on many products. Subway said that it worked hard to 10 the impact of litter on communities, but it was “still down to the individual customer to dispose of their litter responsibly”. Greggs said it recognized the “continuing challenge for us all”, despite having already taken measures to help tackle the issue.
