【题目】阅读下列短文,从每题所给的四个选项(ABCD)中,选出最佳选项,并在答题卡上将该项涂黑。

A

In the fall of 1985, I was a brighteyed girl heading off to Howard University, aiming at a legal career and dreaming of sitting on a Supreme Court bench somewhere. Twentyone years later I am still a brighteyed 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, 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 fulltime. 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!

Everything you want won't arrive in your life in one day. It's a process. Remember: little steps add up to big dreams.
