Article: Though I have traveled in hundreds of trains, few unusual things have ever happened to me. But one day in a train something did happen. I do not mean that I was hurt: no one was hurt. I do my work in a hot country far away from England. Every September I go there to do my business, and every July I come back to England to have a rest. So every September I go to Paris and take a train from the great French city to Mendova, and at Mendova I catch my ship. There is one very fast train from Paris to Mendova, and it suits me well. It goes as far as Endoran, but it stops at Mendova for a few minutes to let travelers get out or in. It is called The Flying Bluebird. It reaches Mendova at seven minutes past nine in the morning, and it is never late. A ship leaves Mendova at half past eleven, and so you will understand that The Flying Bluebird suits me very well. I always travel by it, and I have nearly two and a half hours at Mendova to go from the station to the ship. That is more than enough time. Well, one September night, I took my place in The Flying Bluebird as usual. The train leaves Paris at nine o'clock every night, and I was in my place soon after half past eight. There were three or four people there with me, but very soon a lot of others got into the train. When no more people could sit down, they began to stand up near us and also in the corridor . In a short time the corridor was full too, and it was impossible for any more travelers to get into the train. I could see a lot of other people outside the corridor windows, but they could not get in, and the train left Paris without them. The man sitting next to me started to ask all kinds of questions: "Where do you work? How long does it take you to get there? Are you married? How many children do you have? How much money do they pay you every year? How much do you have in the bank? How much do you spend every month?" He asked questions for about twenty minutes but I did not give him any clear answers, and at last he stopped and began to read the paper. I usually sleep quite well in the train, but this time I slept only a little. There were too many people, and there were too many things: small bags, large bags, coats, hats, boxes, newspapers and food. As usual, we got angry about the window. Most people wanted it shut, and two of us wanted it open. But that always happens. It was shut all night, as usual. When I awoke in the early morning I felt hot and dirty, and glad that the journey was reaching its end. At seven minutes past nine The Flying Bluebird stopped. We were at Mendova, and I stood up thankfully. I took my two suitcases, held one in each hand, and tried to move towards the door into the corridor. In order to get out of the train, I had to pass down the corridor to the door at the far end. There was no other way out. I could not even into the corridor. There was a suitcase on the floor by my feet, and three men were standing in my way. I felt a touch of fear. I had to get out, you see; I had to catch my ship, which left at half past eleven. And the train did not stop again until it reached Endoran, two hundred miles away. "I must get out!" I cried. Everyone there understood me, but no one could move. At last I was able to put one foot over the suitcase on the floor, and I nearly reached the door into the corridor. But then, very slowly, the train began to move. It was taking me away! "Stop!" I cried. "I want to get out!" But no one outside the train could hear me, and the people inside did not care much. The train moved a little faster. What could I do? I was not even in the corridor. Fear made me think quickly. In front of my eyes, just, above the door, was a notice that told everyone how to stop the train. I had to pull an iron thing near the notice. I did not waste time. I pulled it. Well, _ That was to show everyone that there was something wrong. It was not a small sound. Possibly the men in my ship two miles away could hear it. Then the train stopped. No one likes to stop a train if there is no need. But I had to catch my ship. That was the only thought in my mind: to get out and catch my ship.

Article: Like a growing number of young women in Vietnam's northern part city of Haiphong, Pham Thi Hue was infected with HIV by her husband, one of the town's many drug users. But instead of being shamed into silence, as Vietnamese with HIV and AIDS are, the 25-year-old tailor and mother of one went public, appearing on television and at conferences. Her business suffered and her neighbors insulted her, but Hue has now become the public face of Mothers and Wives, an HIV/ AIDS support group established in Haiphong by a Norwegian nongovernmental organization and her neighborhood's People's Committee. Last year, she founded a smaller group named after a local flower. People who need advice on treatment or help preparing bodies for burial can dial a hot line and get assistance from able and sympathetic HIV victims. "We gather to support each other," Hue says. "When we are sick, what we need most is encouragement and comfort from people who understand our situation and are willing to share our happiness, as well as our sadness." On a hot and damp night last month, Hue welcomed into her small home a very thin woman, also a tailor, who was HIV positive. The woman tearfully told Hue that she had not told anyone about her condition, fearing that she would lose customers and that her daughter would be insulted at school. Hue became the wise elder, offering medical and personal advice.
Question: What did Pham Thi Hue do after she was infected with HIV?
Options: (A) She kept silent (B) She worked as usual (C) She stayed at home and cried every day. (D) She went public and gave help to others.

Article: Instagram is a fast,beautiful and fun way to share your life with friends and family.Take a picture or video,choose a filter to transform its look and feel.and then post to Instagram--it's that easy.You can even share to Facebook.Twitter and more.It's a new way to see the world.So many photos of food are contained on Instagram--now a pop-up diner in London is taking advantage of this new trend by letting people settle the bill for their meals simply by uploading photos of their dishes to social networks. I always thought people's taking pictures of their food was kind of silly, but at this new pop-up restaurant in the UK,I'd probably do it too."The Picture House"is the world's first pay-by-photo restaurant--you order, click a photo of the food,share on Instagram and eat for free! The restaurant belongs to frozen food giant Birds Eye,who came up with the idea to cash in on people's addiction with photographing food and sharing the pictures online. They conducted a survey and found out that more than half of the British population regularly took pictures of their meals.So they realized it was a better way to advertise their new dining range. The pop-up diner was open in Soho,London for three days in May,and is now moving to other major UK cities.They serve two-course meals that customers don't have to pay for, if they photo and lnstagram it. The restaurant is a part of Birds Eye's"Food for Life"campaign,a new marketing project that aims at changing the way people look at frozen food."Taking photos of food enables people to show off and to share their mealtime moments--from the everyday to the special,"said marketing director Margaret Jobling. The reaction to The Picture House has been great so far And the pay-by-picture concept has proven to be an effective way.Alternative payment methods are actually gaining popularity among a lot of businesses.Last year in a cafe in Germany customers pay by how much time they spend there,not by what they eat.
