    6．Twelve years ago，I arrived in Central Florida from Puerto Rico．I had heard of a job opportunity and decided to pursue it．But it never became a reality．I quickly learned that being alone without resources in an unfamiliar city was not a comfortable situation to be in．
    Once my limited funds ran out I became homeless and spent a year and a half living on the streets of Orlando．Apart from feeling not being noticed and missing my family，I had to face another challenge-hunger．
    For the first time in my life，I，as a foreign man，who had lived my life in the relative comfort of the middle class，understood the desperation someone feels when they don't get enough to eat．I clearly remembered having run a distance of more than 7miles on many occasions just to make it to a local feeding program before they closed at 7pm．
    Once the need for food was met，the next challenge would arise-where to find a place to sleep for the night．Fortunately，local programs like the Coalition for the Homeless，Second Harvest Food Bank and the Wayne Densch Center were an important part of my ability to survive my painful experience．
    With the assistance of these programs，I was accepted by a college scholarship program through the Coalition and obtained two degrees from Valencia．
    My experience has helped me understand that devoting my life to helping others offers lasting rewards．Today，I am employed as Childhood Hunger Programs Manager at Second Harvest Food Bank and oversees the summer feeding，Hi-Five Kids Pack，and Kids Café programs．I am also proud to be able to distribute（分配） food resources to those wonderful programs and help hundreds more like me．
    24．What can be inferred from Paragraph 1？A
    A．It was impossible for the author to get a job then．
    B．Many local people were out of work in Florida．
    C．Florida is not a good place for people living there．
    D．The author rejected many chances to get a job in Florida．
    25．Why did the author run a distance of over 7miles on many occasions？B
    A．Because he didn't want to be late for work there．
    B．Because he desired to get some free food to eat．
    C．Because he went there to help the poor．
    D．Because he helped distribute food resources to the poor．
    26．Before being accepted by a college scholarship program，the authorC．
    A．had lived with his relatives happily．
    B．had won his degree in a university．
    C．had been struggling financially．
    D．had lost hope of facing the future．
    27．From his experience，the author learned thatD．
    A．misfortune may be an actual blessing．
    B．a friend in need is a friend indeed．
    C．where there is a will there is a way．
    D．one good turn deserves another．

    8．I was the oldest of five children back in the 60's．We lived in a nice little three-bedroom bungalow（平房）in Michigan．Mom and Dad worked so hard，yet always found the time to spend with us．The only place they could take five active children to was the drive-in（汽车影院）movies!
    We always looked forward to going to the drive-in!Mom would fill a big bag with home-made popcorn．On the way there，Dad would make a special stop at the penny candy store，where we were all allowed to fill a little brown bag with all kinds of penny candy．We were so excited，as we carried our treasuresback to the car，knowing we couldn't eat it until the car-toon began．
    We would get there early，so that we could play on the playground，right under the big screen．As soon as it started to get dark，the screen lit up，and we would race bake to the car to get our candy．
    There were always two cartoons playing before the movie，like Felix the Cat，The Coyote，and Tom and Jerry．But what was just as exciting was the ticking clock advertisement for the refreshment stand，with dancing hot dogs，candy and ice cream．That came on right before the movie．It was all that five kids could hope for，and by then，stay awake for．
    We would get home around 2 am，pretty late for us．Mom helped us drag ourselves and our pillows to our beds and dad carried in the little ones．
    I was disappointed the day they closed the last drive-in in our town．It will always hold special memories for us-those days of penny candy．
     
    25．What could the author eat when he watched the cartoons and movies？D
    A．Hot dogs．
    B．Ice cream．
    C．Hamburgers．
    D．Popcorn and candy．
    26．What does the underlined phrase"our treasures"in the second paragraph refer to？B
    A．Mom and dad．
    B．The penny candy．
    C．Favorite cartoons．
    D．Homemade popcorn．
    27．What was the last show before the movie？D
    A．Felix the Cat．
    B．Tom and Jerry．
    C．The dancing hot dogs．
    D．The ticking clock advertisement．
    28．What do we know about the author？C
    A．He had a boring childhood．
    B．He had four younger brothers．
    C．He missed the drive-in very much．
    D．He didn't like watching the movies at all．
