钛(Ti)是一种活泼的金属，其作为金属材料，具有密度小，熔点高，可塑性强、机械强度高、亲生物性能好等优良的性能，有“未来金属”之称。工业上常用硫酸分解钛铁矿石 (FeTiO₃)的方法来制取二氧化钛，再用二氧化钛制取金属钛，主要有以下五个反应：

①FeTiO₃+2H₂SO₄=TiOSO₄+FeSO₄+2H₂O;

②TiOSO₄+2H₂O=H₂TiO₃↓+H₂SO₄;

③H₂TiO₃TiO₂+H₂O；

④TiO₂+2C+2Cl₂TiCl₄+2CO;

⑤TiCl₄+2MgTi+2MgCl₂。

(1)针对以上五个反应，下列叙述错误的是____（填序号）。

A．反应①是非氧化还原反应

B．反应②生成了两种酸

C．反应④中的TiO₂是氧化剂

D．反应⑤表现了金属镁比金属钛的还原性强

(2)钛具有很强的耐腐蚀性，以下对其原因的分析中正确的是____（填序号）。

A．钛是像金、铂一样的不活泼金属

B．金属钛的表面易形成致密的氧化膜

C．钛与氧气、酸等腐蚀剂不反应

D．钛有很高的强度

Like many of my generation, I have a weakness for hero worship. At some point, however, we all to question our heroes and our need for them. This leads us to ask: What is a hero

Despite immense differences in cultures, heroes around the world generally share a number of characteristics that instruct and inspire people.

A hero does something worth talking about. A hero has a story of adventure to tell and community who will listen. But a hero goes beyond mere fame.

Heroes serve powers or principles larger than themselves. Like high-voltage transformers, heroes take the energy of higher powers and step it down so that it can be used by ordinary people.

The hero lives a life worthy of imitation. Those who imitate a genuine hero experience life with new depth, enthusiasm, and meaning. A sure test for would-be heroes is what or whom do they serve What are they willing to live and die for The answer or evidence suggests they serve only their own fame, they may be famous persons but not heroes. Madonna and Michael Jackson are famous, but who would claim that their fans find life more abundant

Heroes are catalysts (催化剂) for change. They have a vision from the mountaintop. They have the skill and the charm to move the masses. They create new possibilities. Without Gandhi, India might still be part of the British Empire. Without Rosa Parks and Martin Luther King, Jr., we might still have segregated (隔离的) buses, restaurants, and parks. It may be possible for largescale change to occur without leaders with magnetic personalities, but the pace of change would be slow, the vision uncertain, and the committee meetings endless.

Although heroes may come from different cultures, they ().

A. generally possess certain inspiring characteristics

B. probably share some weaknesses of ordinary people

C. are often influenced by previous generations

D. all unknowingly attract a large number of fans
