(1)酸雨样品放置时pH变化的主要原因是(用化学方程式表示)____________________。

(2)如果将刚取样的上述酸雨和自来水混合，pH将________(填“增大”“减小”或“不变”)，原因是(用化学方程式表示)____________________。

(3)你认为减少酸雨产生可采取的措施是___________(填字母)。

①少用煤作燃料 ②把工厂烟囱造高 ③燃料脱硫 ④在已酸化的土壤中加石灰 ⑤开发新能源

A．①②③ B．②③④⑤ C．①③⑤ D．①③④⑤

【答案】(1)SO2+H2OH2SO3，2H2SO3+O2===2H2SO4

(2)减小 H2SO3+Cl2+H2O===2HCl+H2SO4

(3)C

【解析】(1)酸雨放置时pH变小，其原因是雨水中的H2SO3被空气中的O2氧化所致。

(2)雨水和自来水混合，应考虑H2SO3与自来水中的Cl2发生氧化还原反应而生成硫酸和盐酸，使酸性增强。

(3)减少酸雨的形成必须减少SO2排放，将煤转化为清洁能源(如煤的气化和液化)，燃料脱硫、固硫，开发不含硫的新能源(如氢能、核能等)，都是有效措施。

阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项。

Charles Dickens (1812—1870), the great nineteenth century English novelist, was born near Portsmouth. His father ran heavily into debt (债) and when he was twelve, he had to go and work in a factory. The only formal education he received was a two-year schooling at a school for poor children. In fact, he had to teach himself all he knew. He worked for a time in a lawyer’s office. After that, he worked as a reporter in the law courts, and later for London newspapers. His life as a writer of novels began in 1833 with short stories and essays in newspapers, and in 1837 his novel “The Pickwick Papers” made him the most popular author at his time in England.

He was a great observer (观察者) of people and their places because he was concerned about life and conditions in mid-nineteenth century London. He wrote 19 novels all his life and in many of them, Dickens gave a picture of all classes of England society, showing deep concern for the poor.

Many of his novels like “Oliver Twist”, “David Copperfield”, “Nicholas Nickleby”, “Great Expectations”, “A Tale of Two Cities” and so on drew attention to the unfair social conditions that existed in England over a hundred years ago. Dickens wished to see improvement in the living conditions of the poor, but failed to find any useful method to achieve that goal.

【1】 Dickens only received a little formal education because ________.

A. he wanted to teach himself

Every day, in all kinds of weather, a lot of people go jogging (running slowly). Why has jogging became so popular? Most people start jogging because you hear it is a very good form of exercise. Jogging makes the heart strong and help people control their weight and stay slim. If you jog regular, you needn’t take pills or skip meals to lose weight. Jogging can also make you to feel better.

Donald Robbins, he is 42 years old and works in an office, began jogging a few years later because he felt he was overweight. At first he could only run 300 metres, and two years later, he ran a marathon — over 42 kilometres.

Do you jog? If you do, be sure to ask your doctor on advice. Does jogging cost much? Almost nothing. But it is very important to have a pair of shoe that are made especially for jogging. If not, when you run on hard ground for a long time it may cause your feet to hurt.

【题目】

Did you see American figure skater, Jeremy Abbott, crash to the ice during the short program at the Sochi Olympics, rolling into the wall, clutching his side in pain. Ten seconds later, he got up and continued his skate—despite the pain, embarrassment and fear. All I could think was: this kid’s got courage. In business we have a word for it—resilience, the ability to gain strengths and confidence from overcoming unpleasant events.

However, opposite examples appeared in Sochi Olympics as well. For them, failure is someone else’s fault, because they do not accept personal responsibility. Therefore, they have to pay a high price for this attitude. After years of studying failure, I have learned one thing: modesty and open-mindedness in the face of mistakes is the single best thing you can do to improve results. Everyone fails, but not everyone recovers from failure. The key is to learn from it rather than get beaten by it.

The good news is that each of us has the potential to live a resilient life on and off the job. It may be difficult, but that just makes it all the more powerful and important. If you believe the above paragraph to be true, then you’re probably more resilient than you think you are. It takes confidence to be resilient but that too much confidence is a killer is so true of leadership. For example, Ron Johnson, the ill-fated CEO of JC Penney, was so stubborn that he completely missed all sorts of signals from employees and customers and instead listened to all those who agreed with him, which failed his strategy. Bouncing back from failure requires that you recognize something has gone wrong, and you were the one who made it happen.

The challenge of resilience is not just about our work. When parents help their kids deal with every challenging situation, they are doing an unhelpful action to their children. Parents want to protect their kids from failure, but doing so takes away the opportunity from them to practice not

just a life skill but an essential work skill. When self-esteem becomes more important than results, we are accidentally training young people to become less adaptable, not more.

Resilience is not just about getting up off the floor, but also being ready for whatever comes next, even when you don’t know what it is. Failures and setbacks are no longer unusual events, but regular features of a dynamic, competitive and highly demanding work environment. Getting up to finish your skate is no longer optional.

【1】The example of Jeremy Abbott shows that one should ______.

A. recover from failure

B. stick to his own viewpoint

C. take others’ opinions to heart

D. challenge difficulties bravely

【2】According to the author, what can best build up resilience?

A. Being positive and powerful.

B. Being competitive and helpful.

C. Being modest and open-minded.

D. Being confident and responsible.

【3】 Which of the following examples shows us resilience?

A. A teacher offers students timely help and care.

B. A determined athlete practices skating hard every day.

C. A confident leader persuades his staff to follow his plan.

D. A student has got a low grade but continues to work hard.

【4】Which might be the best title for the passage?

A. An Example of Resilience: Ron Johnson

B. Resilience: A Lesson from Sochi

C. Optional Challenges of Resilience

D. Resilience in Family Education

Two years before, I traveled to Brazil and I rented for a car. Unfortunate, I had an accident and hit another car, and I needed to stay in a hospital for at least two week. I called my parents, so I did not tell them what had happened. I knew that they will be worried about myself because I was so farther away, and that my mother would not sleep if she knew. Therefore, I told them interested stories and how I was enjoying Brazil. As a result, nobody knew truth. I still think that it was the right thing to do.
