    20．A planet more like Earth than any yet discovered has been identified as a potential future home for mankind．Kepler 22b contains both land and water and has temperatures which average around 72 degrees （22 Celsius）．It also contains the right atmosphere to potentially support life．It is，however，600 light years from Earth．
    The planet，where a year lasts 290 days，was first spotted two years ago．However，NASA scientists using the agency's Kepler space telescope have now concluded that it offers the best hope for future human habitation outside the Solar System．
    One of the key factors for a planet to be habitable is that it remains about the right distance from its main star to be neither too cold nor too hot．
    Bill Borucki，Kepler principal investigator at NASA Research Centre，said，"We are certain that it is in the habitable zone and if it has a surface it ought to have a nice temperature．
    There are now three planets outside the system，known as exoplanets，which experts believe could potentially be occupied by future generations．

    68．Which of the following is most likely to support life for a planet？D
        A．It has 290 days in a year．
        B．It contains both water and land and the right atmosphere．
        C．Its temperatures average 72 degrees （22 Celsius）．
        D．It remains proper distance from its star to have a nice temperature．
    69．What does the new planet have in common with the earth？A
        A．They are habitable for mankind．
        B．They exist in the Solar System．
        C．They have almost the same days in a year．
        D．They are both 600 light years from the sun．
    70．The passage is written to make it known to readers thatB．
        A．there are now three more planets inside the system
        B．NASA's Kepler space telescope finds a"new Earth"
        C．Bill Borucki has confirmed his investigation
        D．it has been two years since a new planet was spotted．
