    20．In the fall of 1985，1 was a bright-eyed girl heading to Howard University，aiming at a legal career and dreaming of sitting on a Supreme Court bench somewhere．Twenty-one years later I am still a bright-eyed dreamer and one with quite a different tale to tell．
      My grandma，an amazing woman，graduated from college at the age of 65．She was the first in our family to reach that goal．But one year after I started college，she developed cancer．I made the choice to withdraw from college to care for her．It meant that school and my personal dream would have to wait．
      Then I got married with another dream：building my family with a combination of adopted and biological children．In 1999，wc adopted our first son．To lay eyes on him was fantastic-and very emotional．A year later came our second adopted boy．Then followed son No.3．In 2003，1 gave birth to another boy．
    You can imagine how fully occupied I became，raising four boys under the age of 8．Our home was a complete zoo-a joyous zoo．Not surprising，I never did make it back to college full-time．But I never gave up on the dream either．I had only one choice：to find a way．That meant taking as few as one class each semester．
      The hardest part was feeling guilty about the time I spent away from the boys．They often wanted me to stay home with them．There certainly were times I wanted to quit，but I knew I should set an example for them to follow through the rest of their lives．
      In 2007，1 graduated from the University of North Carolina．It took me over 21 years to get my college degree!
      I am not special，just single-minded．It always struck me that when you're looking at a big challenge from the outside it looks huge，but when you're in the midst of it，it just seems normal．Everything you want won*t arrive in your life on one day．It's a process．Remember：little steps add up to big dreams．

    A．a writer

    A．She ignored her guilty feeling for her sons．
    B．She wanted to remain a full-time housewife．
    C．She was busy yet happy with her family life．
    D．She was too confused to make a correct choice．

    16．It's natural to greet friends with a smile and a wave．（16）D But what happens if your face and body send mixed messages？Would someone be more likely to believe the look on your face or the way you hold your body？
    Scientists have recently tackled these questions．They found that when a person is looking at your face，she might not believe what she sees if your body language doesn't match the feeling that your face shows．
    （17）A Previously，they had found that the tone of a person's voice can be more important than the words that are spoken．For example，most people tend not to believe a person who says in a flat voice，"I'm so excited．"
    When it came to emotions conveyed by facial expressions and body language，most scientists suspected that the face was more important．To test if this was true，psychologists from the Netherlands and Boston showed people a number of pictures of isolated（孤立的）faces and isolated bodies （with faces blurred out（模糊的）） that showed anger or fear．（18）F
    An angry face had low eyebrows and tight lips．A scared face had high eyebrow and a slightly open mouth．（19）E A scared body had arms forward and shoulders square，as if ready to defend．
    These results told the researchers that mixed signals can confuse people．Even when people pay attention to the face，body language subtly（微妙地） influences which emotion they read．
    （20）C If you want to be understood，it helps to avoid sending mixed messages．

    A．Studying such mixed messages is nothing new for scientists．
    B．Scientists feel new to study the mixed message that confuses people．
    C．So，your body language is important for telling people how you feel．
    D．When you do this，your face and body work together to show your friends that you're happy to see them．
    E．An angry body had arms back and shoulders at an angle，as if ready to fight．
    F．They also showed pictures in which angry or scared faces were paired with angry or scared bodies
    G．Body language can sometimes be misunderstood in different culture backgrounds．
