WASHINGTON--Considering the serious warnings lately about Internet viruses, users may be encouraged to unplug their machines just to keep them safe. In reality, common sense and a few basic tips can keep Internet surfers secure. Antivirus software is a must, and it should be updated at least once a week to recognize newly released viruses. People with broadband Internet connections should also have a firewall. These protect the computer from attacks by hackers. Then it is time to think about computer habits. Unlike old viruses, which spread only through shared diskettes, the Internet brings viruses straight to the email-box. If email with attachment comes from an unknown sender, or unexpectedly from a known sender, it should not be opened. On receipt of an unexpected attachment from a friend, experts suggest a telephone call to make sure of the mail's source before opening. Which of the following is not right according to the passage above? _ . A) We can do something to keep our computers safe B) Antivirus software made in 1995 is hard to protect our present day computers C) We should unplug our computers to drive off viruses D) An email attachment even coming from a friend may not always be safe to be opened

Thailand's capital Bangkok is both attractive and wonderful, a city of glass towers and concrete buildings crowded with nearly 10 million people. The ground beneath is spongy and moist. Imagine a brick resting on top of a birthday cake. That's Bangkok-and it's sinking into the Earth at an alarming rate. Thailand's disaster specialists have been warning of this coming disaster for years. One expert has said he's worried about Bangkok resembling Atlantis. Another previously told Global post that the city will be under five feet of water by 2030. The latest estimates suggest that Bangkok is now sinking as fast as two centimeters per year in parts of the city. The predictions for 2100 are even more terrible. By then , Bangkok will be fully submerged and unlivable. Like global warming, which will accelerate the city's submersion by raising the sea leavel, Bangkok's sinking problems are repeatedly _ But the monsoon season, currently underway, tends to bring this crisis to mind. A nasty storm can suddenly turn Bangkok's streets into gushing streams. Sewers overflow, taxis move through dirty water and, occasionally, kids can pick up displaced fish. Anond Snidvongs, director of the Southeast Asia Regional Research Center, predicts the city's outskirts will be the first to go. Parts of the shoreline ebyong Bangkok are already liend with pumps that make noises and help to transform invading seawater. They don't always work. During heavy rains, salt water flows in the streets of the city. Bangkok is swallowed up a little more each day. Experts tend to offer two solutions. The first is to pu up a massive seawall that could cost nearly $3 billion-nearly 1 percent of Thailand's current GDP. The second option is to give up entirely and move the capital to higher ground. Why is Bangkok sinking into the earth? A) Its buildings are too heavy. B) It has an overlarge population. C) Its underground is too loose. D) It is resting on top of a lake.

Q: My life suffered a lot in summer five years ago. My father died in a car accident,leaving my mother,my two younger brothers and I alone. At that time,I was a senior high school student. After my father's funeral,I had no choice but to drop out of school and work in a factory. I really wanted to return to school and wanted to go to college,but I couldn't. I only hoped to bring up my two young brothers. Life was not easy for me,for I can't afford their tuition even if I worked from day to night without stopping. Without my father's protection,I thought I was a slave to the fate. Later on,something changed my life. I still remember that it was a rainy day. I put myself in the rain and walked slowly in the street. Suddenly the rain stopped!I raised my head and found "the sky" was in fact a dark blue umbrella. Then I noticed a middleaged man with one leg on crutch standing behind me. He said to me,"Why not run without an umbrella?If you didn't run,you would get drenched." The man told me that he was a promoter. He once dreamed of being a policeman,but an accident ruined his dream. Though his present job was not suitable for his legs,it was a wonderful start to him. He was very happy that he didn't lose heart and still "ran" on the road of life... I was encouraged by the man's words. I went to a big city and became an assurance representative. After two years' running,I did well and my family condition turned better little by little. Later I returned to school and succeeded in my entrance to university. Life is like this. When you are in rainy days in your life,if you couldn't find a way to prevent you from being wet,you would be overwhelmed. But if you decide to get rid of it,you'll discover that the rainy days last not so long as you imagine. What happened to the writer at the beginning of the story? A) His father died in a car accident six years ago. B) He had to drop out of school to look after his sick mother. C) He couldn't afford his two brothers' tuition even if he worked from day to night.

We discuss the issue of when to help a patient die. Doctors of our generation are not newcomers to this question. Going back to my internship days, I can remember many patients in pain, sometimes in coma , with late, hopeless cancer. For many of them, we wrote an order for heavy medication--morphine by the clock. This was not talked about openly and little was written about it. It was essential, not controversial. The best way to bring the problem into focus is to describe two patients whom I cared for. The first, formerly a nurse, had an automobile accident. A few days later her lungs seemed to fill up; her heart developed dangerous rhythm disturbances. So there she was: in coma, on a breathing machine, her heartbeat maintained with an electrical device. One day after rounds, my secretary said the husband and son of the patient wanted to see me. They told me their wife and mother was obviously going to die; she was a nurse and had told her family that she never wanted this kind of terrible death, being maintained by machines. I told them that while I respected their view, there was nothing deadly about her situation. The kidney failure she had was just the kind for which the artificial kidney was most effective. While possibly a bit reassured, they were disappointed. Here was the head surgeon seemingly determined to keep everybody alive, no matter what. Within a few days the patient's pacemaker could be removed and she awoke from her coma. About six months later, the door of my office opened and in walked a gloriously fit woman. After some cheery words of appreciation, the father and son asked to speak to me alone. As soon as the door closed, both men became quite tearful. All that came out was, "We want you to know how wrong we were." The second patient was an 85-year-old lady whose hair caught fire while she was smoking. She arrived with a deep burn; I knew it would surely be deadly. As a remarkable coincidence there was a meeting for discussion going on at the time in medical ethics . The speaker asked... At the meeting, the author discussed with the students _ . A) the importance of mercy killing B) the relationship between mercy killing and ethics C) the case about an old lady D) the process to practice mercy killing
