A.B超

B.放射性核素扫描

C.CT

D.131I摄取率

E.MRI

答案

参考答案:B

   I know we don't have many serious talks, but now that I am on the edge of being an adult, I feel that

you need to know and understand me. During the past nine years that we have been in America, I have

grown greatly, changed from that wide-eyed and scared little girl to a proud and brave young woman.

The change wasn't always smooth, and I wasn't always patient, but you were both always understanding.

And through your understanding I have learned.

   I have learned from you. Dad, you wake up every morning to go to the steel plant, where people don't

speak your language and you don't speak theirs. I know that if you were in Vietnam, you would be

comfortably surrounded by friends. But you are here in America, doing what you don't like, and through

that, you are teaching your children the power of persistence.

   I have learned from you, Mom, you cook nice Vietnamese sour soup and fish, wait up at nights for

your daughters. When I see you pacing back and forth because your daughters aren't home yet, I cry

because I see so much pain in your eyes, and through your pain I learn the meaning of home a sanctuary

that I will always be able to turn to.

   Through all your sacrifices I learn the essence of being human. I learn to love. I find that this love leads

me to you, to the home, to the fact that I am Vietnamese-American. The dreams that you have taught me

slowly begin to take shape as I walk down the college path, step into the adult world and adventure out

of your world. Wherever I go, I carry my past with me, knowing that you will always be there behind me

and I will always come back, because you are where my home is.
