March 20th is World Water Day every year. According to a report from the United Nations, more than half of the world's major rivers have serious water loss and are polluted.

The Yellow River, the world's fifth longest river, watered some of the oldest farms on earth. But now it has a serious problem.    1.    In most of the past 35 years, it didn't reach the sea.

The Nile in Egypt, running 6, 650 km, is the longest river in the world. 2.Now it is down to 2 billion m' or so.  Australia's Murray River reaches the sea only every other year.  One fifth of America's Rio Grande has no water, either.

____3.   

Mostly it's damming (筑坝) and global warming that make rivers dry.

____4.    Now about 45, 000 of them lie across the world's rivers. They hold back around 15% of the world's fresh water from running to the sea.

Global warming is making things worse. Warmer weather takes water away.  The glacier (冰川) are becoming smaller.   5.    Global warming has had certain effects on water sources (源头). Droughts (干旱) happening around the world make people pay more attention to this fact.

 

 

A. Dams hold water to irrigate (灌溉) fields and make power. B. The source of the Yellow River is drying up because of it. C. It used to carry 32 billion m' of water a year. D. How does it happen? E. Factories pour waste water into rivers directly. F. Its source on Qinghai-Tibet Plateau is drying up.

I will never forget the very moment that caused me to leave my gift behind because I wanted the gift that my older sister Maria had.
My family was spending a week at the beach. One morning, Maria went to the beach early, but I stayed behind to finish a drawing of a seashell. After finishing the drawing, I walked to join Maria. She was a top gymnast (体操运动员). Her show was perfect as she wheeled along the beach. The beauty of that sight froze me, and I decided immediately that I too would become a gymnast like her.
I knew that I had never been very good at sports. However, when I told my parents I wanted to take a gymnastics class, they agreed with me in surprise. The next week, I went to a beginners’ class.
If only my parents had talked me out of this misguided plan! Five minutes into the first class, it was clear that I didn’t have the gift of a gymnast. But I kept at it.
During this time, drawing and painting—which had been my two favorites—all but left my mind. It must have been hurting for my family as they watched my hopeless efforts. I blindly decided to be like Maria. I just would not give up.
At the same time, on the advice of Ms. White, my art teacher, I hurriedly handed in my seashell drawing for an art contest in our town. One night as I was having a hard time practicing, the phone rang. It was Ms. White. “Alice, you won the contest!” she said loudly.
“Really?” was all I could reply.
“Yes,” Ms. White said. “They’re going to give you a prize. And that’s not all. The winner is also accepted into Wildale’s Summer Fine Arts Institute.” I couldn’t believe what I heard. Only a handful of young artists were accepted each summer.
That night I didn’t go back into the living room to continue practicing. Gymnastics was Maria’s gift, not mine. It had taken me a while, but I realized that I had a gift of my own.
