When I go to Chinatown to have meals with my parents, I’m always taken to the bet table and treated with warm smiles and polite service by the waitress.
You may think that I would be popular in Chinatown because I look Chinese. But hundreds of men and women are like me in New York and they actually get little attention there. We all are ABCs （American–born Chinese）and we don’t speak Chinese.
Whether it’s in a market, or in a restaurant, our treatment is always the same. ABCs are greeted with a smile and friendly words in Chinese at first. Then, when they discover that we don’t understand Chinese, their smiles and their friendliness disappear（消失）.
It can be embarrassing. For example, one time when I went to a restaurant with my father, a waitress asked me something in Chinese after she chatted with my father. “She doesn’t speak Chinese,” my father said. The woman’s face turned red. “What? You never taught her?” she asked.
Actually, when I was a little girl, my parents sent me to learn the Chinese language and the culture. But I dropped out when I was seven. I had better things to do on my weekends – mainly to play with my non–Chinese, American friends. But no I think I should have learned some Chinese when I was young.

D. afraid
( ) 55. The underlined phrase in the passage has the similar meaning to “”.
A. gave up

A. The waitresses in Chinatown are not friendly.
B. The writer thinks ABCs should learn some Chinese.
C. The Chinese language is very popular in America.
D. ABCs are not welcomed in Chinatown in America.
B
Mr. Brown and his wife moved into a new city. The next morning, while they were eating breakfast, Mrs. Brown saw her neighbor drying clothes that had just been washed outside. “Those clothes are not very clean,” she said. “She doesn’t know how to wash clothes correctly. Perhaps she needs better soap.”
Mr. Brown looked up, but remained silent. Every time their neighbor hung her clothes out to dry, Mrs. Brown was surprised to see nice clean clothes on the line and said to her husband, “Look! She has learned how to wash clothes correctly. I wonder who taught her this.”
Mr. Brown said, “I got up early this morning and cleaned our windows!”
And so it is with life: What we see when watching others depends on the purity（纯度）of the window that we look through. Before we say anything bad, it might be a good idea to check our minds and ask ourselves if we are ready to see something good rather than to look for something bad in the person.

Do you really care about your parents? 85 this question, most of us may give a quick answer “Of course, I do.” But maybe you don’t.
