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，we 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，I 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, I 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.

　　To tell you the truth，the students in our class have different opinions. About 70% of the students think that we shouldn't bring mobile phones to school.Because with them we may not fix our attention to the lessons. If the phone is not turned off by chance and the ringing will destroy the class.Furthermore，using mobile phones will add to our parents' economic burdens.However，about 30% of the students think we can bring phones to school on condition that we turned off them in class.With a mobile phone it is convenient for us to keep in touch with our parents and friends.Besides，the mobile phone is a tool of information times.It may not be right to ban students from carrying mobile phones.，
