    　　Do you want to live another 100 years or more?Some experts say that scientific advances will one day enable humans to last ten of years beyond what is now seen as the natural limit of the human life span．

    　　“I think we are knocking at the door of immortality(永生),”said Michael Zey, a Montclair State University business professor and author of two books on the future．“I think by 2075 ________ and that’s a conservative estimate(保守的估计)．”

    　　At the conference in San Francisco, Donald Louria, a professor at New Jesery Medical School in Newark said advances in using genes as well as nanotechnology(纳米技术)make it likely that humans will live in the future beyond what has been possible in the past．“There is a great push so that people can live from 120 to 180 years,” he said．“Some have suggested that there is no limit and that people could live to 200 or 300 or 500 years．”

    　　However, many scientists who specialize in aging are doubtful about it and say the human body is just not designed to last past about 120 years．Even with healthier lifestyles and less disease, they say failure of the brain and organs will finally lead all humans to death．

    　　Scientists also differ on what kind of life the super aged might live．“It remains to be seen if you pass 120, you know, could you be healthy enough to have good quality of life?”said Leonard Poon, director of the University of Georgia Gerontology Center．“At present people who could get to that point are not in good health at all．”

    　　Open Your Eyes And Let's See Who You Are

    　　Inventors have developed a new way to identify people, using a machine that scans their eyeballs．Developed by eyes scan, this new technology takes advantage of the fact that the iris(虹膜)of each person's eye is unique, and remains unchanged throughout a lifetime．

    　　The process will replace ________called retina(视网膜)identification, which compared the pattern of veins(静脉)in the back of the eye．Used to control access to nuclear weapons, retina identification has never caught on with the public because it requires the user to put their eyeball right up against a lens．Iris scanning, on the other hand, works from a distance．

    　　The iris of the eye is photographed from up to one meter away．The patterns of the iris are translated into digital code, and stored in a PC database, along with personal information．Glasses and contact lenses do not interfere with the scanning process, and it takes only a brief moment．

    　　The new technology will be useful for banking and police work, as well as for the Internet economy．Before long, your computer monitor may be equipped with an iris scanner that can identify you when you shop online, thus preventing fraud．

    　　There will be no ID cards to carry in your pocket, and no long numbers to memorize．And eyes will be very difficult to counterfeit．

    　　Did you lose your ID card?No, you didn't．It's still right up there beside your nose．

    　　[1]Have you ever been offered an alcoholic drink? What about someone's saying “Don’t worry, just have one little sip”? Most people have their first drink by the time they’re 13．That first drink can be the start of a troubled life．

    　　[2]Drink can make teens feel good, but that feeling lasts only a short time．Alcohol clouds your brain and hinders your ability to make decisions．Excessive drinking literally makes your brain shrink and can cause serious damage．Over-drinking can cause learning disabilities and damage your memory．It distorts your vision and leads to blackouts．Teenagers often think that drinking will give them more energy, but alcohol isn’t an energy drink－it’s a depressant(镇静剂)

    　　[3]Drunk driving is one of the top causes of __________ for teen boys．An alcohol-related motor vehicle crash kills one person every 33 minutes and injures someone every two minutes．The rate of teen drunk driving is so high that the government is trying to pass new laws to restrict teen driving．

    　　[4]When we get to high school, friends start pressurising us to drink．High school students see alcohol as glamorous and a way to become popular．I conducted a survey at my school．24 of the 63 respondents predicted they would drink in high school．11 said maybe, and 28 said they didn’t plan on drinking．

    　　[5]Regardless of what they say now, things can change．Teens starting high school want to fit in．They think that one drink won’t do anything harmful．A little bit of alcohol probably won’t kill you, but it can lead to poor decisions．High school is the time to experiment with what you want to do in life, but if you’re experimenting with alcohol you could hurt someone, including yourself．

    阅读下面短文并回答问题，然后将答案写到题后相应的位置上(请注意问题后的字数要求)。

    　　[1] High school is thought by many to be an exciting time when you make lasting friendships and look forward to college life．However, as all young people know, high school is full of pressures．

    　　[2] Fitting in is not only a major part of middle school and high school, but it is also crucial throughout life．The dream of being one of the “in-crowd” isn’t a desire you can simply tell yourself not to have; it’s something you should try to avoid．

    　　[3] Teachers and parents constantly tell us to be ourselves, but many of us have no idea who we really are．Those around us will always influence the choices and decisions we make．So how do you break the pattern? How can you pull away from the trends of today and make something that’s truly your own?

    　　[4] First, you need to gather up some courage, because being different from everyone else can be a little nerve-racking(令人紧张的)．

    　　[5] Secondly, if you want to get anywhere, you must stop comparing yourself to others．Set aside any insecurity, because when it all comes down to it, you are who you are, and that’s all you will ever be．

    　　[6] Others will always influence you, and that’s OK; it’s human nature．But don’t become a clone just so you can get to the top of the social pyramid．

    　　[7] It will be tough at first, but if you show others that you are confident in yourself, I can tell you firsthand that they will become more accepting of the way you are．

    1．What is the main idea of the text?(no more than 8 words)

    _________________

    2．Why is it difficult to be ourselves?(no more than 8 words)
