阅读理解

    I was 8 years old when I found out my father was ill. It was 1993, but I can remember my mother's words as if it were yesterday. “Jessica, I don't want you to take food from your father, because he has AIDS. Be very careful when you are around him.”

    AIDS wasn't something we talked about in my country when I was growing up. From then on, I knew that this would be a family secret. My parents were not together anymore, and my dad lived alone. For a while, he could take care of himself. But when I was 11, his condition worsened. My father's other children lived far away, so it fell to me to look after him.

    We couldn't afford all the necessary medication for him, and because Dad was unable to work. I had no money for school supplies and often couldn't even buy food for dinner. I would sit in class feeling completely lost, the teacher's words muffled as I was thinking how I was going to manage.

    I didn't share my burden (负担) with anyone. I had seen how people reacted to AIDS. Kids laughed at classmates who had parents with the disease. And even adults could be cruel. When my father was moved to the hospital, the nurses would leave his food on the bedside even though he was too weak to feed himself.

    I had known that he was going to die. But after so many years of keeping his condition a secret, I was completely unprepared when he reached his final days. Sad and hopeless, I called a woman at the nonprofit (非营利的) National AIDS Support. That day, she kept me on the phone for hours. I was so lucky to find someone who cared. She saved my life.

    I was 14 when my father died. He took his secret away with him, having never spoken about AIDS to anyone, even me. He didn't want to call attention to AIDS. I do.

又是荠菜花开时

    我的童年是在江南广阔的田野里度过的,那里是我的活动室。这个活动室是现在幼儿园的小朋友们所无法想象的。那可真是个激动人心的世界,蕴藏着无穷无尽的乐趣。无论是春夏,还是秋冬,那里都有许多东西令我兴奋激动,其中就有荠菜。

    兴奋激动的理由,主要不在她的美味,而在于寻找她的过程。荠菜善变,不仅颜色变,形状也会变。长在没有太多杂草的地方,她是匍匐在地上的,叶子呈锯齿状,有时候那锯齿还很大,整片叶子看上去像从叶子中间的茎上又生出许多瘦长的叶子来,而且颜色很深,灰紫色,不仔细找,根本发现不了。如果长在菠菜地里,她就往上长,叶子几乎没有齿,而且颜色碧绿,和菠菜的模样十分相似。如果周围有些浅浅的、灰绿色的草,她既不匍匐着,也不高高站着,颜色也就变成灰绿,叶子有浅齿,和周围的草一样,叶表一层细细的茸毛,这就又和采杂草打成一片了。所以,每找到一棵,都是一次胜利。有时候,第一遍没有发现,但有些疑惑,一回头,突然发现一个肥大的家伙正趴在那里呢。这时候,会感觉胸腔里那颗心正激动得怦怦直跳。这不像是在干活,而像捉迷藏,甚至比捉迷藏还好玩,谁不愿意呢?五六岁的时候,如果让我看守晒在场上的稻谷,驱赶麻雀和鸡,我是不愿意的,太乏味了。如果母亲说:“海度啊,去挑点荠菜来,晚上包团子吃”,我就兴高采烈,拿了篮子雀跃而去。

又是烟花三月、荠菜开花的时候了,不知道江南的孩子还能否认识荠菜,也不知道被春雨浇醒的田野里是否还有挑荠菜的妇女、孩子。
