Article: Half a year before graduation from college, my son David began to seek a job. Due to the financial crisis, the competition was ever-fierce. My son targeted a company that was located in a coastal city. It was intended to employ only one person among more than twenty candidates, I said to David, "You should not harbor too much hope for fear that you would feel terribly disappointed when you fail." He said to me, "I am not afraid of disappointment. As long as I try, there will always be hope!" Three young men could enter the final round, which would later decide one person to be employed. Everything seemed to go quite well and David entered the final round in a week. Unexpectedly, the interview was unbelievably simple, during which the interviewer only chatted with them for a while. The interview strategies my son prepared were not useful at all. The interviewer said the company would inform them of the result in 3 days. On the morning of the third day, David received the text from the company that he was not employed. David felt disappointed. In nightfall that day, David suddenly told me excitedly on phone that he had been employed. Greatly surprised, I asked him, "What's the whole matter?" David told me that he received another text saying that he was employed. David felt very confused about it. Later he found out the first text sent to him was also part of the test in the interview. Three men received the same text this morning and only David's reply was satisfying to the company. I asked my son, "How did all of you reply?" My son said, "One did not reply. The other said "goodbye" and I said "thank you"." Only then did I know that my son's "hope" came in that way. That is, when you feel disappointed, do not forget to say "Thank you" to the one who disappoints you. Actually, it is a piece of cake to say "Thank you". Saying "Thank you" shows respect for others' work and demonstrates your grand generosity. Therefore, while under the same condition, you will get the upper hand in terms of opportunities compared... Question: When David got the job offer, he felt _ at first. Yes or no, is the answer "puzzled"?
No

Article: Retold by Laura E.Richards All day long the little boy had worked hard, in the field and barn and shed, for his parents were poor farmers, and could not pay a workman.But at sunset there came an hour that was all his own, for his father had given it to him.Then the boy would go up to the top of a hill and look across at another hill that rose some miles away.On that far hill stood a house with windows of clear gold and diamonds.They shone so brightly that it made the boy squint at them, but after a while the people in the house put up shutters, as it seemed, and then it looked like any common farmhouse.The boy supposed they did this because it was suppertime; and then he would go into the house and have his supper of bread and milk, and go to bed. One day the boy's father called him and said: "You have been a good boy, and have earned a holiday.Take this day for your own, and try to learn some good things." The boy thanked his father and kissed his mother.Then he put a piece of bread in his pocket, and started off to find the house with the golden windows. It was a pleasant walk.His bare feet made marks in the white dust, and when he looked back, the footprints seemed to be following him, and keeping him company.His shadow, too, kept beside him, and would dance or run with him as he pleased; so it was very cheerful.By and by he felt hungry, and he sat down by a brown stream that ran through the alder hedge by the roadside, ate his bread, and drank the clear water.Then he scattered the small pieces of bread for the birds as his mother had taught him to do, and went on his way. After a long time he came to a high green hill, and when he had climbed the hill, there was the house on the top.But it seemed that the shutters were up, for he could not see the golden windows.He came up to the house, and then he could well have wept, for the windows were of clear glass, like any others, and there was no gold anywhere about them. A woman came to the door, looked kindly at the boy, and asked him what he wanted. "I saw... Question: The author's main purpose in including the character of the girl in this story is _ . Yes or no, is the answer "to present the boy with a different view of his own house"?
No

Article: A dense wave of smog began in the Chinese city of Harbin and the surrounding Heilongjiang, Jilin, and Liaoning Provinces on 20 October 2013. Unseasonably warm temperatures with very little wind across northeastern China coincided with the smoke from local farmers' burning straws and the start-up of Harbin's coal-powered central heating system. Record densities of fine particulates were measured in the city. In Harbin, the levels of PM2.5 (particulate matter) rise to 1,000 micrograms per cubic meter, worse than Beijing's historic highs. Visibility was reduced to below 50m in parts of Harbin, and below 500m in most of the neighbouring Jilin Province. On Fa Yuen Street in Harbin, visibility of less than 5m was reported. The smog reduced after October 23, 2013 and completely broke up on October 28, 2013 by the first local snow and icy rain due to a cold front moving in from Russia. Harbin lies in the north of China where winter temperatures can drop to -40degC, demanding a six-month heating season. Daily particulate levels of more than 40 times the World Health Organization recommended maximum level were reported in parts of Harbin. The smog remained till 23 October, when almost all monitoring stations in Heilongjiang, Jilin,and Liaoning Provincesreported readings above 200mg/m3forPM2.5. PM2.5 is the amount of particulate matter less than 2.5 micrometers in diameter in the air, with the WHO recommending a maximum 24-hour mean of 25 micrograms per cubic meter (mg/m3). On the morning of 25 October, PM2.5 measurements in Harbin had fallen to an average of 123mg/m3. All highways in the surrounding Heilongjiang Province were closed. In Harbin, all primary and middle schools were closed for three days and authorities stopped flights at the airports. Hospitals reported a 23 percent increase in admissions for breathing problems. However, this smog will have no influence on Harbin Ice Festival events later in December 2013. Air pollution in Chinese cities is of increasing concern to China's leadership. Particulates in... Question: One cause of the heavy smog in the northeastern Chinese cities may be _ . Yes or no, is the answer "the start-up of heating system"?
