British and American scientists are raising genetically modified  pigs in the hope of providing organs for transplant  to humans, the project leader wrote in a newspaper Sunday.  Scientists in London and California have begun conducting the genetic experiments to find a solution to record-long waiting lists for organ transplants, Robert Winston said in an opinion piece written for Britain's Sunday Times.  In Britain alone, around 8,000 patients are waiting for a transplant.  "People needing a new heart or liver are waiting for someone else to die -usually a violent death in a traffic accident," Winston wrote in the newspaper. He said his team was "trying to modify pigs so their organs might save the lives of humans."  The scientists are introducing human genes into the animals to reduce the chances of the organs being rejected by patients, as has been common in previous attempts to use animal tissues, said Winston, who heads the Institute of Reproductive and Developmental Biology at London's Hammersmith Hospital.  Working with Dr. Carol Redhead of the California Institute of Technology, Winston's team has injected human genes directly into male piglets , adding them to the animal's sperm .  He said that pigs involved in experiments had successfully produced transgenic sperm, but acknowledged that British and European laws had prevented the team from using the pigs to mate.  The Sunday Times newspaper reported that the experiments would be moved to the United States following difficulties with funding and regulations in Britain. It said the pigs would be bred in Missouri.  "Our U.S. friends will benefit from our technology and the income we might have produced for Britain will be lost," Winston wrote.  Some scientists have previously blamed the idea of using animal organs for human transplant, saying the technique risks spreading animal viruses to humans. Winston said his research project is attempting to breed virus-free pigs. It can be inferred from the passage that   _  . A) animal organs are commonly used for human transplant now B) lots of patients need animal organ transplants now C) examples of the animal tissues being rejected have happened D) it is not safe to use animal organs for human transplant

(Question)
Dear friend, For the past 17 years, you have been my best friend. I remember that you told me you were called Cigarette because of your features. You have seen me through difficult times, happy times and just about every stage of my life. You have always been here when I need you. Some of my family and friends didn't like you so much, but I've always been on your side. I thought you were a great friend, and I _ you at all times, especially when I was not very happy. It's hard for me to tell you this, but in the past few months, I have been seriously thinking about ending our relationship. I think that I've just been too dependent on you, and I feel that at the age of 35 I should start being more independent. I thought about just maybe seeing you once in a while, but I don't think that would work. Eventually, I'd start relying on you all the time again. I feel the only way to end our relationship is to end it forever. I've always included you in everything I've done. But next week, I'm going on a trip, and I've decided not to take you along. I feel this would be a good time to break up. I will be gone for a whole week without you and if I can make it on my own for that week, I know I can make it forever. It is a little sad for me knowing that I won't be able to rely on you any more, but I think I will be a better person in the end. The author decided to take a trip to   _  . A) get away from his best friend B) relax himself for a while C) reduce his sorrow for the break D) show that he is independent

Ques: I was very disappointed not to be able to go to the jazz concert last Friday. The announcement in the paper said that you could buy tickets at the theatre box office in Richland Hills any day between 10:30 a.m. and 4:00 p.m. Since I work from 9:00 a.m. to 5:30 p.m., the only time I could go to the theatre was during my 45-minute lunch break. Unluckily, the theatre is on the other side of the town, and the bus service between my office and Richland Hills is not very good. But if you are lucky, you can make the round trip in 45 minutes. Last Monday, I stood at the bus stop for 15 minutes waiting for a bus. By the time I saw one come around the corner, there was not enough time left to make the trip. So I gave up and went back to the office. The same thing happened on Tuesday, and again on Wednesday. On Thursday, my luck changed. I got on a bus right away and arrived at the theatre in exactly 20 minutes. When I got there, however, I found a long line of people at the box office. I heard one man say he had been waiting in line for over an hour. Realizing I would not have enough time to wait in line, I caught the next bus and went back across the town. By Friday, I realized that my only hope was to make the trip by taxi. It was expensive, but I felt it would be worth to hear the concert. The trip by taxi only took 10 minutes, but it felt like an hour to me. When I got to the theatre, I was _ to see that nobody was waiting in line. The reason, I quickly discovered, was that they had already sold out all the tickets. He failed to get the ticket on Friday because   _  . A) it was impossible to make the round trip to the theatre in 45 minutes B) the concert wasn't on Friday C) it was expensive to take a taxi D) all the tickets had been sold out
Ans: D


Ques:BERLIN (Reuters)--Germany's postal service has announced plans to explore improved service and help protect the environment by getting "fetch friends"--ordinary people traveling across cities--to deliver parcels on their way. It is hoped that the move, which will be tested in the coming months, might lessen traffic in inner cities and reduce CO2emissions . This should help DHL, a division of the German postal service, reach its target of improving the company's carbon efficiency by 30 percent before 2020. "As the world's biggest logistics  provider, we recognize a special responsibility to reduce the impact on the environment as much as possible," said Frank Appel, Chief Executive Officer of Deutsche Post DHL, in a statement referring to a variety of measures being considered. The "fetch friends" find out online about parcels that need delivering to people who live or work along the way that they are planning to travel through the city. They then select the ones that they want to take. Codes  sent to their mobile phones tell the volunteers where to pick the packages up. Parcels can be taken part of the way or passed on to another volunteer but all volunteers need to have the right code on their mobile phone so the track and trace system can be updated. Logistics companies will be responsible for looking after the operation to make sure that the privacy of post is respected. It's hoped that this could be done using mobile phones but DHL says it recognizes that some security issues remain to be worked out. What may be a problem with the new service according to the article? A) Volunteers' not allowing to select parcels. B) The wrong codes in the mobile phones. C) The possibility that parcels could be opened on the way. D) Parcels' being taken to the destination by a single volunteer.
