How far would you be willing to go to satisfy your need to know? Far enough to find out your possibility of dying from a terrible disease? These days that's more than an academic question, as Tracy Smith reports in our Cover Story. There are now more than a thousand genetic tests, for everything from baldness to breast cancer, and the list is growing. Question is, do you really want to know what might eventually kill you? For instance, Nobel Prize-winning scientist James Watson, one of the first people to map their entire genetic makeup, is said to have asked not to be told if he were at a higher risk for Alzheimer' . "If I tell you that you have an increased risk of getting a terrible disease, that could weigh on your mind and make you anxious, through which you see the rest of your life as you wait for that disease to hit you. It could really mess you up." Said Dr. Robert Green, a Harvard geneticist. "Every ache and pain," Smith suggested, "could be understood as the beginning of the end." "That 's right. If you ever worried you were at risk for Alzheimer's disease, then every time you can't find your car in the parking lot, you think the disease has started." Dr. Green has been thinking about this issue for years. He led a study of people who wanted to know if they were at a higher genetic risk for Alzheimer's. It was thought that people who got bad news would, for lack of a better medical term, _ . But Green and his team found that there was "no significant difference" between how people handled good news and possibly the worst news of their lives. In fact, most people think they can handle it. People who ask for the information usually can handle the information, good or bad, said Green. Which of the following is true about James Watson? A) He doesn't want to know his chance of getting a disease. B) He is strongly in favor of the present genetic tests. C) He believes genetic mapping can help cure any disease. D) He is more likely to suffer from Alzheimer's disease.

Mayor Boris Johnson Monday outlined plans to make London "the cleanest" by the 2012 Olympics and called for commitments from other world cities at a climate change conference. Leaders of the world's 40 largest cities are meeting in Seoul this week for a summit on _ global warming ---- the third to be held since 2005. "What we should do in Seoul is agree that we will stop the endless addiction of mankind to the internal combustion engine ," said Johnson. He told a press conference the world's cities consume 75 percent of its energy and produce 80 percent of the emissions which cause climate change. "The problem of our planet is an urban problem," Johnson said. He said the British capital wants to use the Olympics "to drive the greening and the improvement of our city" and noted that London is committed to reduce carbon emissions by 60 percent by 2025. Johnson said the key measure was addressing the problems relating to domestic and commercial buildings, which accounted for 70 percent of carbon dioxide emissions in London. This involved retrofitting ---- installing lagging ---- in large numbers of public buildings. Johnson proclaimed himself a "passionate cyclist" and said he would push ahead with cycle super-highways around London. London's air quality problem, he said, was caused by vehicle emissions from 8,300 antiquated diesel buses, which could be replaced by low-carbon vehicles. There were also 32,000 taxis running on diesel fuel, which could be replaced by electric vehicles. Johnson said there would be a substantial program in the next few years to produce a "cleaner, greener" bus for his city. "The age of the diesel-emitting bus has got to be over in London." If the passage was continually written, the following might be _ . A) measures to replace the old and used vehicles B) measures to reduce carbon dioxide emissions in London C) measures to solve housing and commercial items D) measures to end the age of the diesel bus

About this time every year, I get very nostalgic . Walking through my neighborhood on a fall afternoon reminds me of a time not too long ago when sounds of children filled the air, children playing games on a hill, and throwing leaves around in the street below. I was one of those children, carefree and happy. I live on a street that is only one block long. I have lived on the same street for sixteen years. I love my street. One side has six houses on it, and the other has only two houses, with a small hill in the middle and a huge cottonwood tree on one end. When I think of home, I think of my street. Only I see it as it was before. Unfortunately things change. One day, not long ago, I looked around and saw how different everything has become. Life on my street will never be the same because neighbors are quickly grown old, friends are growing up and leaving, and the city is planning to destroy my precious hill and sell the property to contractors. It is hard for me to accept that many of my wonderful neighbors are growing old and won't be around much longer. I have fond memories of the couple across the street, who sat together on their porch swing almost every evening, the widow next door who yelled at my brother and me for being too loud, and the crazy old man in a black suit who drove an old car. In contrast to those people, the people I see today are very old neighbors who have seen better days. The man in the black suit says he wants to die, and another neighbor just sold his house and moved into a nursing home. The lady who used to yell at us is too tired to bother any more, and the couple across the street rarely go out to their front porch these days. It is difficult to watch these precious people as they near the end of their lives because at once I thought they would live forever. The "comings and goings" of the younger generation of my street are now mostly "goings" as friends and peers move on. Once upon a time, my life and the lives of my peers revolved around home. The boundary of our world... The writer finds it hard to accept the fact that _ . A) many of his good neighbors are growing old B) the lady next door who used to yell at him and his brother is now a widow C) the life of his neighbors has become very boring D) the man in his black suit even wanted to end his own life
