    4．Soon computers and other machines will be able to remember you by looking at your eyes!The programme works because everyone's eyes are different．So in the future you won't have to remember a number when you want to use a machine or take money out of a bank．You'll just have to look at the machine and it will be able to tell who you are．
    The eye-recognition（识别）programme is already being tested in shops and banks in the USA，Britain，Spain，Italy and Turkey．Soon，this technology will take the place of all other ways of finding out who people are．
    However，scientists are working on other systems．Machines will soon be able to know you from the shape of your face or hand or even your smell!We already have machines that can tell who you are from your voice or the mark made by your finger．
    Eye-recognition is better than other kinds because your eyes don't change as you get older，or get dirty like hands or fingers．And even twins have different eyes，so the programme can be up to 94% correct，depending on how good the technology is．Some programmes may only be right  51% of the time．In Britain，it was found that 91% of people who had tried it said that they liked the idea of eye-recognition．In the future your computer will be looking at you in the eye．So smile!

    38．How does the eye-recognition programme work？C
    A．You write your number．
    B．You show your ID card．
    C．You look at the machine．
    D．You say your name．
    39．Why can the programme be up to 94% correct？A
    A．Because eyes never change．
    B．Because hands or fingers can get dirty．
    C．Because people like the idea of the programme．
    D．Because the programme is widely used around the world．
    40．Which of the following is true？B
    A．The programme is being tested in Japan．
    B．Machines with other systems can also tell who you are．
    C．91% of people like the idea of the programme．
    D．Computers can remember you by looking at your clothes．
    41．What does this passage mainly talk about？B
    A．Introduction to some kinds of programmes．
    B．Introduction to the eye-recognition programme．
    C．The way how the eye-recognition programme works．
    D．The places where the eye-recognition programme is tested．

    9．The sun beat down on Zhang Tingjun as she ran the"City of Peace"marathon （马拉松） in Dili，East Timor，last June．As the 28-year-old came up to the finish line，she felt something rising in her throat （喉咙）．When she was done，she caught sight of her three running mates and saw that they were also troubled by emotion．It was not because their unpleasant experience was over．For Zhang and her friends，each step they took would help save a life．
    It all started in July 2009 when the four young Singaporean women decided to go on an adventure （历险） together．Someone suggested a five-day bicycle race and they jumped at it．
    Soon they were talking about the poverty （贫穷） that has troubled East Timor．"The conversation slowly turned to a common subject-to use adventure as a chance for change，"Zhang recalls．They set up The Chain Reaction Project （TCRP），with the goal of using their love for sport and adventure to help the poor．
    In addition to their four-hour-a-day training plan，they asked families，friends and workmates for donations （赞助）．Their first efforts raised just 78．Then out of the blue，Zhang's friend，Ivy Singh Lim，donated﹩15，550．"To have someone believe what we are doing means more than the money in my hand，"says Zhang．In all they raised more than﹩35，000．
    The four friends arrived in Dili in August 2009，several days ahead of the start of the race．Needing a place to stay，they took up an offer to camp at HIAM Health，a children saving center．
    During their week at the center，the women learned that more than half of Timorese children under five don't have enough food．They also discovered that the center was trying to get enough money to prove what it could do to help．TCRP came to a decision the money they had raised would go to HAIM Health．
    One child at the center rounded Zhang's heart．Two-year-old Sarah came from a poor family．"Sometimes the children's condition is so bad that they cannot grow normally．But Sarah received help early enough and became all right soon，"Zhang recalls．
    When the TCRP members returned for the 2010 Dili marathon，they were joined by 18 other runners．The group raised﹩10，000 for HIAM Health，as well as a﹩21，750 playground donated by Playpoint Singapore．Today HIAM Health plays an important role in poor children's lives．
    TCRP next plans to climb Mount Kilimanjaro，the highest mountain in Africa，in February 2011．Their goal：to raise at least﹩30，000 for AIDS children．
    "We know a﹩10，000 donation isn't going to save the world，"Zhang says．"The effort of a group of people will be far greater than the four of us can achieve on our own．"

    57．Which of the following is the four women's first adventure？A
    A．The five-day bicycle race．
    B．The"City of Peace"marathon．
    C．The camping during night．
    D．The climbing of Kilimanjaro．
    58．Who did the TCRP members want to help at the beginning？A
    A．The poor in East Timor．
    B．Friends and workmates．
    C．Children who need food．
    D．Children who are badly ill．
    59．How much did the TCRP raise in the 2010 Dili marathon for HAIM Health？C
    A．﹩10，000．
    B．﹩15，550．
    C．﹩31，750．
    D．﹩35，000．
    60．The underlined sentence means thatD．
    A．the more people believe what we are doing，the more money we can raise
    B．to make people believe what we are doing is harder than to raise money
    C．our next goal is to make much more people believe what we are doing now
    D．it is more important to make ourselves understood than to raise money．
