閱讀下列短文，從每題所給的四個選項（A、B、C和D）中，選出最佳選項。
Charles Dickens (1812—1870), the great nineteenth century English novelist, was born near Portsmouth. His father ran heavily into debt (債) 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 (觀察者) 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.

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.

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.

【題目】
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.
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.
