地球上的金属资源广泛存在于地壳和海洋中,除少数很不活泼的金属如金、银等以单质形式存在外,其余都以化合物的形式存在。陆地上存在各种各样的金属矿藏。
部分常见的金属矿石
从矿石中制取金属单质的过程叫冶金。金属作为金属材料,其价值不仅取决于它在地壳中的含量和独特的性能,在很大程度上还取决于其冶炼的难易程度。例如铝是人们熟悉的金属,其蕴藏量居金属之首,应用广泛。但在1886年以前,它的价格比黄金还高,其原因是冶炼成本太高。目前工业冶炼铝的原理是将铝土矿提纯后,在熔融状态下电解,生成铝和氧气。
早在春秋战国时期,我国就开始生产和使用铁器。从1世纪起,铁成了一种最主要的金属材料,工业上可利用一氧化碳还原赤铁矿制得金属铁。
金属除了有光泽、导电性、导热性、延展性等共同的物理性质外,还有各自的特性。例如,铁、铝等大多数金属都呈银白色,但铜呈紫红色;常温下大多数金属是固体,但汞是液体。
金属材料应用广泛。形状记忆合金是具有形状记忆效应的合金,人造卫星和宇宙飞船上的天线是由钛镍形状记忆合金制造的,它具有形状记忆功能,可揉成一团放入卫星或宇宙飞船舱
内,需要时可在一定条件下恢复原来的抛物面形状。钛合金与人体具有很好的“相容性”,因此可以用来制造人造骨等。
人类每年要从自然界提取数以亿吨计的金属,但矿物的储量有限,因此,对金属资源的保护变得迫在眉睫。
9.(2017辽宁沈阳,17,8分)人类制得并利用金属有着悠久的历史:
?

①Cu2(OH)2CO32CuO+H2O+CO2↑,该反应的类型是反应(填“化合”“分解”或“置换”);
②2CuO+C2Cu+CO2↑,该反应前后铜元素化合价发生的变化是。
(2)高炉炼铁的主要反应过程如下,请写出对应的化学方程式:

10.(2016吉林,16,4分)下图为铁制品循环利用的示意图,根据图示回答:
(1)从“①”“②”“③”中,选出一定发生化学变化的是(填序号);
(2)不能用铁制容器盛放硫酸铜溶液的原因是(用化学方程式表示);
(3)废旧金属“循环利用”的意义是(写一点即可)。
11.(2015湖北襄阳,46,2分)钢铁在生产、生活中有着广泛的用途。请回答:
(1)炼铁厂常以焦炭、赤铁矿石(主要成分是Fe2O3)、空气等为主要原料炼铁,请写出一氧化碳与氧化铁在高温下反应的化学方程式:。
(2)每年全世界钢铁的产量很高,但钢铁的锈蚀也给人类带来了巨大的损失。请你写出一种防止铁锅生锈的方法:。
12.(2014重庆,20,4分)钢铁是使用最多的金属材料。
(1)人类向大自然提取量最大的金属是铁。写出高温下一氧化碳把铁从赤铁矿石中还原出来的化学方程式。
(2)锰(Mn)钢属于铁合金,可用于制造钢轨。取少量锰钢碎屑加入盛有足量稀盐酸的烧杯中,浸泡以后烧杯底部剩有固体,该固体中一定含有。已知锰的金属活动性强于锌,如果用实验比较铁和锰的金属活动性强弱,下列所给试剂组能够达到目的的是(填序号)。
A.Fe、Mn、40%H2SO4溶液
B.Fe、Mn、MgSO4溶液

You should write at least 120 words but no more than 180 words. Much controversy has been aroused about whether the students should find a job or start their own business after graduation.Taking a look around,we can find that some graduates bustle around job markets,while others choose to run a shop on TMall. However, I prefer the former choice. From my perspective, there are good reasons to find a job in the first several years after their graduation.First and foremost, if a graduate intends to accumulate working experience and learn from the seniors, it is advisable for him to find a job. It is an undeniable fact that the theoretical knowledge will provide the graduates with the ability to consider things comprehensively,however,only under the integration with practice can the rigid knowledge be useful for their future development. Inevitably, doing something small is the premise of undertaking something great. Take Jack Ma, the founder of Alibaba and taobao, for example. He also finds some jobs before establishing his own career,laying a solid foundation for his later success. Consequently,it is of great necessity to find a job after graduation.I firmly believe that it will continue to bring about more returns to our life and future.

You are required to select one word for each blank from a list of choices given in a word bank following the passage. Read the passage through carefully before making your choices. Each choice in the bank is identified by a letter. Please mark the corresponding letter for each item on Answer Sheet 2 with a single line through the centre. You may not use any of the words in the bank more than once. When someone commits a criminal act, we always hope the punishment will match the offense. But when it comes to one of the crudest crimes—animal fighting—things __26__ work out that way. Dog-fighting victims are __27__ and killed for profit and “sport,” yet their criminal abusers often receive a __28__ sentence for causing a lifetime of pain. Roughly half of all federally-convicted animal fighters only get probation （缓刑）. Some progress has been made in the prosecution（起诉）of animal fighters. But federal judges often rely heavily on the U.S. Sentencing Guidelines when they __29__ penalties, and in the case of animal fighting, those guidelines are outdated and extremely __30__ . The U.S. Sentencing Commission, which __31__ these sentencing guidelines, is revisiting them, proposing to raise the minimum sentence from 6-12 to 21-27 months. This is a step in the right __32__ , but we’d like to see the U.S. Sentencing Commission make further changes to the guidelines.
