2017年12月英语六级考试真题试卷附答案第三卷

2017年12月英语六级考试真题试卷附答案(完整版第3套) Part I Writing (30 minutes) Directions: For this part, you are allowed 30 minutes to write an essay commenting on the saying "Help others, and you will be helped when you are in need." You can cite examples to illustrate your views. You should write at least 150 words but no more than 200 words. ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ Part Ⅰ Writing Be Generous with Your Help When it comes to the topic of help, we are frequently told that, "Help others, and you will be helped when you are in need. '' Simple as the saying is, it implies the importance of helping others in need. What I learn from the remark, in short words, is that helping others is helping yourself. Examples can easily be found to make this point clearer. The story of the ant and the dove is a case in point. An ant slipped into the river when drinking along the river. A dove heard his cries for help and threw him a leaf, which helped the ant float back to the bank. After a few days, a hunter was raising his gun to the dove as she was building her nest. Seeing this, the ant ran quickly to bite the hunter's leg. The dove heard the hunter's scream and flew away. All in all, this example indicates that when we offer our help to others, we are leaving a way open for the future. Helping others is a virtue, and we should take some measures to carry forward this virtue and do others a favor. Only in this way can we build a loving and harmonious society.

2017年12月六级仔细阅读真题及解析(卷二)

Passage One Questions 46 to 50 are based on the following passage. You may have heard that Coca-Cola once contained an ingredient capable of sparking particular devotion in consumers: cocaine. The “ coca” in the name referred the extracts of coca leaf that the drinks originator, chemist John Pemberton, mixed with his sugary syrup(姜汁).At the time, coca leaf extract mixed with wi ne was a com mon tonic(滋补品),and Pembert on ' s sweet brew was a way to get around local laws prohibiting the sale of alcohol. But the other half of the name represents another ingredient, less infamous(名声不好的),perhaps, but also strangely potent: the kola nut. In West Africa, people have long chewed kola nuts as stimulants, because they contain caffeine that also occurs naturally in tea, coffee, and chocolate. They also have heart stimulants. Historian Paul Lovejoy relates that the cultivation of kola nuts in West Africa is hundreds of years old. The leafy, spreading trees were planted on graves and as part of traditional rituals. Even though the nuts, which need to stay moist, can be somewhat delicate to transport, traders carried them hundreds of miles throughout the forests and grasslands. Europeans did not know of them until the 1500s, when Portuguese ships arrived on the coast of what is now Sierra Leone. And while the Portuguese took part in the trade, ferrying nuts down the coast along with other goods, by 1620, when English explorer Richard Jobson made his way up the Gambia, the nuts were still peculiar to his eyes. By the late 19th century, kola nuts were being shipped by the tonne to Europe and the US. Many made their way into medicines, intended as a kind of energy boost. One such popular medicinal drink was Vin Mariani, a French product consisting of coca extract mixed with red wine. It was created by a French chemist, Angelo Mariani, in 1863. So when Pemberton created his drink,it representedan ongoing trend. When cocaine eventually fell from grace as a beverage ingredient, kola-extract colas became popular. The first year it was available, Coca-Cola averaged nine servings a day across all the Atlanta soda fountains where it was sold. As it grew more popular, the company sold rights to bottle the soda, so it could travel easily. Today about 1.9 billion Cokes are purchased daily. It' s become so iconic that attempts to change its taste in 1985 sweetening it in a move projected to boost sales —proved disastrous, with widespread anger from consumers. -“CoClaocCalassic ,”returned to store shelves just three months after the “New Coke” was released. These days, the Coca-Cola recipe is a closely guarded secret. But it' s said to no longer contain kola nut extract, relying instead on artificial imitations to achieve the flavour. 你可能听说可口可乐曾经含有一种能够使消费者“死忠”的成分:可卡因名中的“ coca”指的是古柯叶的提取物,该饮料的创始人化学家约翰?彭伯顿用它与含糖的姜汁混合在一起。当时,古柯叶提取物与葡萄酒混合是常见的滋补品,而当地法律禁止出售含酒精饮料,彭伯顿的甜饮则避开了该法律。“cola ”代表另一种成分——可乐果:尽管名声不太好,但非常给力。 在西非,人们长期以来一直嚼着可乐果作为兴奋剂,因为它们含有咖啡因。咖啡因在茶、咖啡和巧克力中也天然存在。它们也有心脏兴奋剂。

2017年湖南省高中学业水平历史科考试大 纲 篇一:2017年湖南省学业水平测试高中历史必修1复习 2017年湖南省高中学业水平考试·历史必修1复习 2017-2-22 必修1 第一单元中国古代的政治制度 (理解)(1)目的:建立侯国,拱卫王室,为了进行有效的统治;(“封建亲戚,以藩屏周”)(2)内容:周王把王畿以外地区的土地和人民分封给诸侯;(3)分封对象:王族、功臣、古代帝王后代;(4)受封诸侯的权力和义务: 权力:职位世袭、对卿大夫再分封、设置官员、建立武装、征派赋役 (天子--- 诸侯--- 卿大夫--- 士)。 义务:服从周王命令、镇守疆土、随从作战、交纳贡赋和朝觐述职。

(5)特点:层层分封,带有宗族统治的色彩,形成贵族统治阶层内部的森严等级“周王—诸侯—卿大夫—士”。(6)作用: 积极:西周通过分封制,加强了对地方的统治,开发边远地区,扩大统治区域。形成对周王室众星捧月般的政治格局。 消极:后来诸侯国中出现了强国兼并弱国的形势,使周天子的权威逐渐削弱。 (7)瓦解:西周后期,王权衰弱,分封制受到破坏(根本原因在于封建生产方式的产生,这一生产方式使诸侯势力日益壮大)。战国末年,分封制瓦解。 (8)影响:由于受封诸侯在自己的领地内,享有相当大的独立性,长远来看不利于中央集 权。到西周后期,王权衰弱,分封制遭到破坏。秦朝建立以后,在地方废除分封制,实行有利于中央集权的郡县制。教材P.5-6 2、宗法制(理解)
