If you're hungry for more history, head for the Olive Tree Museum inVouves, which dives into the history of the industry.Sardinia, ItalyThe Giants of Mont'e Prama—15 large sandstone heads said to be 3,000 years old—wereunearthed in 1974 by two farmers who worked in the field. Their age connects them to the island's mysterious 神秘的） Nuragic civilisation. See the figures at Cagliari's National ArchaeologicalMuseum. Within the same museum lie other important finds, which help to paint a picture of the civilisation's livelihoods.Isle of Skye, ScotlandIt'd be a surprise that a lyre said to be about 4,Oo0 years old was found on Scotland's Isleof Skye in 20l2. The discovery tugged(拨动) on the heartstrings of islanders whose past hasbeen underpinned by a love of traditional folk music, often featuring stringed instruments.The islanders host many live music events every year.

Lucaswas not like the others because he suffered from a disease known as bumblefoot, whichincludes a range of bad foot conditions that stop animals from standing upright, and a lack oftreatment can lead to possible death.For Lucas, life had been a series of treatments and disappointments(失望). The zoo'steam had tried everything,but nothing seemed to work on his disease. Dr. Beth Bicknese, amember of the zoo's team, said, “I've looked after Lucas for years. I am very sad when Lucasdevelops pains."Then, there was a hope. The zoo's team got the help of Thera-Paw, a company thatdesigns products to help animals move better.“The orthopedic shoes(矫形鞋） from Thera-Paw help Lucas to fully join the group and show behaviors that are more typical for a penguin—such as climbing the rocks, swimming,nesting and finding a suitable mate," said Dr.Beth Bicknese.Debbie Denton, a senior wildlife care specialist in the team, was there when Lucas first said. “Seeing him move about now gives us hope that he may be OK going forward and able to【英语试题第3页（共8页）】25-L-256A

5.据史书记载，唐德宗时期，御史中丞突参“不避权贵，理狱以严称，数蒙召见，论天下事，又与执政多异同，上深器之，或参决大政，时宰颇忌之，多所排抑，亦无以伤参“。由此可知，御史中丞的设置A.加强了君主权力B.完善了中央官制C.保障了吏治清明D.减少了决策失误6．“科差”是元朝出现的赋税名目，主要包括“丝料”“包银”“俸钞”等项内容，以户为征税单位，户的等级决定了“科差”的轻重。征收对象为一般民户，不包括儒士及军、站、僧、道等户。“科差”制度的实施表明，元朝A.再现了前代的人头税制度B.推行崇文重教的文化政策C.放松了对黎民的人身控制D.实行较为宽松的宗教政策7.明朝成化初年，都御史韩雍奏准于肇庆、梧州等地设立抽盐厂，对过往盐商“每官盐一引抽银五分，许带余盐四引，每引抽银一钱“。弘治二年（1489），又将允许销带余盐的数量增加到六引，“仍照前例抽收”。上述举措客观上A.削弱了政府的监管职能B.改变了盐场的经营方式C.推动了盐业市场的发展D.缓解了盐商之间的矛盾8.1898--1899年间，梁启超曾借《法兰西革命记》的著述，将法国大革命比同中国古代革命，利用易代鼎革中被革者的亡国意象，强调变法维新的重要性。1899年，他在《清议报》刊文指出，法国大革命的发生是因为民众追求“自由权”。这表明梁启超A.阶级属性发生根本变化B.政治立场超出改良范畴C.放弃变法转向支持共和D.维护皇权独尊意识增强9.1909年，清政府颁布《大清国籍条例》，除标题中有“大清”二字外，正文内容全都以“中国“取代”大清“。清末”新政“时期，清政府颁布的政今、法今等，均普遍使用”中国“作为国名。“中国”一词频现反映了当时A.中国国际地位的显著提高B.专制王朝向民主政体转型C.清廷彻底抛弃狭隘民族观D.主权国家意识的日益增强告10.图1为20世纪20年代初刊登在《东方杂志》上的一则广告。该图可以佐证厨天A.新文化运动逐步深人B.民族工业发展的轨迹C.实业救国思潮的兴起D.国民政府的经济政策图1高三历史试题第2页共6页
