[EX Q]: Article: Have you heard of the scandal that happened in one of Great Britain's biggest supermarket chains called Tesco? The British love Tesco as it sells very cheap products and it can be found on almost every corner of a British city or town. On January 15th 2013 food inspectors discovered 30 % horsemeat in a certain brand of frozen beefburgers that were mostly sold by Tesco in the UK and Ireland. In times of social media like Facebook and Twitter the news has spread fast and customers have been very concerned about what the food they buy actually contains. Tesco said it had taken away the burgers from the shop shelves immediately, and apologized to their customers. They also promised that they would find out what exactly happened and that they would work harder than ever so this would never happen again. Customers are also able to return the beefburgers and get a refund, that is, their money back. However, it will be hard for Tesco to get the people's trust back. Just imagine buying lovely beefburgers that you fry at home and suddenly you find out that you have actually eaten horsemeat! In this case not only horse lovers will be upset! By the way, why are British people so shocked about eating horsemeat? In history, horses have played great roles as working animals and as an important means of transport. When Britons of today think of horses, they think of majestic animals or cute pets rather than meat. But this is not the only reason for the protest: Customers also want to be sure that the products they buy contain what it says on the label. Hopefully, supermarkets can avoid mistakes like that in the future. Maybe there should be stricter regulations and more controls of our food? Otherwise we will soon find ourselves eating panda meat instead of pork and parrot instead of chicken. So the next time you are in a supermarket maybe check the ingredients of your food before you buy it or you could get a nasty surprise ...

[EX Q]: Article: My first reaction was annoyance. It was Friday afternoon, and I was within an hour of finishing my work for the week. As I was leaving, a nurse brought me one more patient message. The statement read: "Mm. Jones called to say that she has had blurred vision ever since her medical test this morning. " I smiled. Suddenly our tests were causing eye problems. This week my patients had questioned everything. My patient with high blood pressure had stopped coming to her treatment on the advice of an Internet chat room. A woman who had a mental problem was substituting (......) St. John' s word for her medication. Now Mrs. Jones was imagining problems. I rolled my eyes. My second reaction was worry. As I looked through her record, I tried to figure out why she would have blurred vision, but nothing in her record explained the new problem. She' s probably just anxious, I thought. Still, she wouldn't have called if she had been all right. I picked up the phone. What 1 next felt can only be described as delight. Before I made the call, the nurse ran in: Mrs. Jones called. Her vision is fine. Turns out she picked up the wrong glasses when she left the office. The X-ray technician has been having the same problem. I let out a lugh. Mrs. Jones had been right. Her vision had been blurred. Now we know why. Finally I felt shame. I came to realize what Mrs. Jones had taught me. I had first known she was wrong, that her anxiety had _ . Instead, my medical training had clouded mine. Now I feel thankful that Mrs. Jones figured it out before I made a mistake about our relationship. Patients come to me for my help. They pay me to listen, diagnose , treat and talk. That suggests trust; I must remember that, and trust them too.

[EX Q]: Article: Last week, I bought an alarm system for about $ 450. It consisted of a control unit with three other small units. I put the control unit in the sitting room and fastened the other units by the front door, back door and living-room windows. The instructions told us to choose three numbers, so we chose 491, the last three numbers of our telephone number. Now I must explain how the alarm works: 1. There is a power siren in the control unit. It makes a very loud noise. 2. Each of the small units sends out beams or rays in different directions. If anything moves, it breaks a beam. This sends a signal to the control unit. The siren makes a noise that you can hear 50 meters away. 3. When we go to bed, I press the three buttons numbered 4, 9 and 1. Then we have 30 seconds to get out of the room before the alarm starts to work. That might I slept soundly because I was sure that no burglar could get into our house. However, at about 2:10a.m., I woke up and heard the siren . "There must be a burglar in the house," Mary said. "What shall we do?" "I'll go and see who's there," I said. "Stay here. Don't make a noise." I went downstairs quietly. When I reached the living room, I switched on my torch and looked round the room. Then I turned the light on. I switched the siren off and searched the rooms downstairs. There was nothing wrong except that the back door was unlocked. I locked it, re-set the alarm and went back to bed. About an hour later, the alarm started again. I jumped out of bed, fell over a chair in the dark and bumped into the bedroom door. Mary woke up and started hitting me with a torch. "Hey! Wait a minute!" I whispered. "It's only me. I' m going downstairs to see what's wrong." I went down into the living room and listened for a moment. The only sound I could hear was the siren. I turned on the light and then switched the siren off. As I did so, I glanced across at the curtains in front of the windows. I saw a house lizard disappear behind the curtains. "Oh!" I said to myself. "That's our burglar." When the lizard moved, it started the siren. I guessed that the alarm had been made in Europe, where there are no house lizards. Well, I won't finish this story but if you want an alarm system free of charge, let me know. I'll send you ours. We bought a dog this morning. It knows the difference between a lizard and a burglar.
