考题根据以下材料，回答题 The men and women of Anglo-Saxon Englandnormally bore one name only. Distinguishing epithets were rarely added.These might be patronymic, descriptive or occupational. They were, however,hardly surnames. Heritable names gradually became general in the threecenturies following the Norman Conquest in 1066. It was not until the 13th and14th centuries that surnames became fixed, although for many years after that,the degree of stability in family names varied considerably in different partsof the country. British surnames fall mainly into four broadcategories: patronymic, occupational, descriptive and local. A few names, it istrue, will remain puzzling: foreign names, perhaps, crudely translated, adaptedor abbreviated; or artificial names. In fact, over fifty per cent of genuineBritish surnames derive from place names of different kinds, and so they belongto the last of our four main categories. Even such a name as Simpson may belongto this last group, and not to the first, had the family once had its home inthe ancient village of that name. Otherwise, Simpson means "the son ofSimon", as might be expected. Hundreds of occupational surnames are atonce familiar to us, or at least recognisable after a little thought: Archer,Carter, Fisher, Mason, Thatcher, Taylor, to name but a few. Hundreds of othersare more obscure in their meanings and testify to the amazing specialization inmedieval arts, crafts and functions. Such are "Day" (old English forbreadmaker) and "Walker" (a fuller whose job was to clean and thickennewly made cloth). All these vocational names carry with them acertain gravity and dignity, which descriptive names often lack. Some, it istrue, like "Long", "Short" or "Little", aresimple. They may be taken quite literally. Others require more thinking; theirmeanings are slightly different from the modem ones. "Black" and"White" implied dark and fair respectively. "Sharp" meantgenuinely discerning, alert, acute rather than quick-witted or clever. Place-names have a lasting interest sincethere is hardly a town or village in all England that has not at some timegiven its name to a family. They may be picturesque, even poetical; or they maybe pedestrian, even trivial. Among the commoner names which survive withrelatively little change from old-English times are "Milton" (middleenclosure) and "Hilton" (enclosure on a hill). The underlined word"epithets" in Paragraph 1 most probably means ________.查看材料A.a name shared by all the members of afamily B.a word in front of a person's name toshow their rank or profession C.an offensive word or phrase that is usedabout a person or group of people D.an adjective or phrase that is used to describesomebody/something's character or most important quality

考题根据以下材料，回答 Trogmire Troll was dealing with acrisis. The new girl in class really liked him a lot. Trogmire was not happyabout it. Trogmire′s good friend, Tremor Troll, triedto comfort him. "What′s thebig deal? I think Treasure Troll is kind of cute. And she seems to be niceenough." Trogmire swallowed his last bite of poisonsumac salad and glared at Tremor. "Then why don′t you ask her to be yourgirlfriend? There she is, sitting all by herself at the other end of thecafeteria. March over there and ask her to be your sweetie-poo!" "She′ s crazy about you, not me,"Tremor replied. "Well, I don′t want any girlfriend,especially not a weird pesky one like her!" Trogmire growled. Tremor wouldn′ t give up. "The onlything pesky about her is that she keeps writing you those notes and shestares." "Yucky love notes!" Trogmireinterrupted. He took another sip of mole milk. "Did you notice those strange browneyes? Why aren′ t they normal red or pink?" Tremor took another look at Treasure."I think her face is a lovely shade of green. And her dark green curlyhair is quite pretty. Besides, she′ s very sweet and that′ s what reallymatters." Trogmire stuck out his tongue. "I think I′m going to be sick!

考题根据以下材料，回答 It′s one of our common beliefs that miceare afraid of cats. Scientists have long known that even if a mouse has neverseen a cat before, it is still able to detect chemical signals released from itand run away in fear. This has always been thought to be something that is hard-wiredinto a mouse′ s brain. But now Wendy Ingram, a graduate student atthe University of California, Berkeley, has challenged this common sense. Shehas found a way to "cure" mice of their inborn fear of cats by infectingthem with a parasite, reported the science journal Nature. The parasite, called Toxoplasma gondii,might sound unfamiliar to you, but the shocking fact is that up to one-third ofpeople around the world are infected by it. This parasite can cause different diseasesamong humans, especially pregnant women--it is linked to blindness and thedeath of unborn babies. However, the parasite′s effects on mice areunique, Ingram and her team measured how mice reacted to a cat′ s urine (尿) before and after it was infected by the parasite. They noted thatnormal mice stayed far away from the urine while mice that were infected withthe parasite walked freely around the test area. But that′s not all. The parasite was foundto be more powerful than originally thought--even after researchers cured themice of the infection. They no longer reacted with fear to a cat′s smell, whichcould indicate that the infection has caused a permanent change in mice′ sbrains. Why does a parasite change a mouse′s braininstead of making it sick like it does to humans? The answer lies in evolution. "It′s exciting scary to know how aparasite can manipulate a mouse′s brain this way," Ingram said. But shealso finds it inspiring. "Typically if you have a bacterial infection, you go to a doctor andtake antibiotics and the infection is cleared and you expect all the symptomsto also go away." She said, but this study has proven that wrong. "This may have huge implicationsfor infectious disease medicine." Which of the following statements istrue according to the passage?A.Toxoplasma gondii causes people strangeand deadly diseases. B.With certain infection the infectiousdisease cannot be cured completely. C.Human beings infected by toxoplasmagondii will have permanent brain damage. D.Toxoplasma gondii is harmful to humanbeings, but it does no harm to mice.
