Article: Recently, China UnionPay did an experiment in a subway station in Beijing--Are you willing to offer a hand to a stranger who needs help? The leading role of the experiment was an old man. With a small bag in one hand and a large case in the other, the old man appeared in a cold winter morning in the bustling  subway station. He was so old that he couldn't carry the heavy case up the stairs. Standing in front of the steps, he looked helpless. Something good happened finally. At 9 o'clock, a kind man showed up, he offered to carry the case for the old man and walked up the stairs with him, at 9:25, another man helped ... Within six hours,the old man walked up the stairs for 25 times,among which he was helped for 23 times. What's more,two ladies tried to help the old man--one in the front and the other in the back. They carried the case up the stairs for him. The most noteworthy thing was that another old man tried to help too. When these kind people were asked why they helped the stranger,they all said " It's just the right thing to do," "I always help people as long as I can" ,or "it's not a big thing, and I just want to help". We often see negative news about fake falling and blackmailing or scheming  and cunning. But this experiment brought sheer warmth into our heart. Question: What do we know about the old man? Yes or no, is the answer "He helped to do the experiment."?
Yes

Article: In my long years of teaching, I often ask my students to read the texts until they can recite them, and I tell them that recitation is an important part of their homework. However, some of my students are tired of doing so, thinking that it is both hard and useless. They argue that it takes a long time to recite a text from memory and text itself never appears in a test paper. In my opinion, it naturally takes time to recite a text, but it is worth doing so. When you are able to recite a text, you are sure to be familiar with the words and expressions. When you need them in reading or writing or doing exercises, they will come to your mind quickly, and so you will give quick response to all kinds of language situation. How can we say that it is useless? Besides, many students complain that they soon forget what they were once able to recite. This is true, but you don't need to worry. While you are reading and forgetting the texts, your language   level is being raised. Sure you don't remember your Chinese texts that you once read in the primary school, but now you are able to read novels and newspaper. So, recitation of the texts will help you improve your language ability. Question: What do the students think about the teacher's advice?  _ Yes or no, is the answer "The English teacher asks them to do something useless."?
No

Article: It was the last time Susan Butcher ran the Iditarod Trail Sled Dog Race in 1992. An hour into the race, Susan and her sled dog team sped down a hill and crashed into a fallen tree. Although hurt, Susan continued the difficult race. The Iditarod Race started in 1925 when a doctor in Nome, Alaska was desperately in need of medicine to stop the spread of a deadly disease. Only a hospital had what he needed, but it was 700 mile-away! In January, it was too dangerous to send a boat and too stormy for his tiny airplane. The only hope was to use several sled dog teams following a trail, called the Iditarod Trail. They passed the medicine from one sled team to another. Wind and snow did not stop the men and their dogs. The medicine was delivered in record time. The race follows the route of the famous medicine run. Over 1,000 miles long, it is considered the toughest race in the world. Susan Butcher was born in Cambridge, Massachusetts. In her teens Susan was given a Siberian husky dog and became very interested in huskies as sled dogs. After reading about the Iditarod Race, Susan moved to Alaska. She got several jobs to earn money to buy herself a sled and a team of huskies. After years of hard work and training, Susan achieved her dream of racing on the Iditarod Trail. In 1978, at the age of 24, Susan entered the race for the first time and became the first woman to finish in the top 20. In 1982 she came in second. In 1984 she was leading her team across a frozen waterway when they fell into the water. Her lead dog managed to pull Susan and the other dogs out of danger. Remarkably, she came in second. In her fourth race, in 1985,a starving moose  attacked her dogs, killing two and injuring eleven. Susan had to leave the race. In 1986 Susan joined the race again. This time, she won. She won again in 1987. In 1988 she became the first person ever to win three Iditarod races in a row.  Unbelievably, Susan won for the fourth time in 1990.
