题目:

材料一 黄河是一条多沙的河流,中上游每年输出泥沙16亿吨,经河口入海的约有12亿吨。而黄河在利津入海口的潮流作用很弱,河口潮流的落差通常只有0.8~1.0米。由于潮流弱、搬运能力差,黄河入海的泥沙约有40%在河口附近淤积,河口两侧的堆积体以每年2~3千米的速度向海洋延伸,黄河三角洲也以很快的速度向海洋扩展。

材料二  黄河入海口海岸变迁示意图

(1)依据材料判断黄河三角洲面积变化的趋势并分析成因。

This was the first real task I received in my new school. It seemed simple: go on the Internet and find information about a man named George Washington. As I searched the name, I found that there were two famous people having the same name who looked completely different! One invented hundreds of uses for peanuts(花生), while the other led some sort of army across America. I stared at the screen, wondering which one my teacher meant. I called my grandfather for a golden piece of advice; let the coin decide. I flipped(掷) a coin and Ah! Tails (背面)! My report would be about the great man who invented peanut butter, George Washington Carver.

Weeks later, I stood in front of the classroom and proudly read my homework. But things started to get strange. I looked around the room, only to find my classmates with big smiles on their faces and tears in their eyes and my stone-faced teacher. I was completely lost. “What could be causing everyone to act this way?”

Oh well, I dropped the paper and sat down at my desk, burning to find out what I had done wrong. As a classmate began his report, it all became clear, “My report is on George Washington, the man who started the American War of Independence.” The whole world became quiet! How could I know that my teacher meant that George Washington?

Of course, my subject result was awful. Sad but fearless, I decided to turn this around. I talked to the headmaster Miss Lancelot, but she said firmly: No re-dos; no new score. I felt that it was not fair, and I believed I deserved a second chance. So I threw myself heartily into my work for the rest of the school year. Ten months later, I sat in the headmaster’s office again, but this time a completely different conversation. I smiled and flashed back to the terrible moment at the beginning of the year as the headmaster told me I was good enough to skip(跳过) the 6th grade and started the 7th grade next term.
