　　答案：

　　 Last month, I, as well as my parents, invited to my uncle's home in the United States. My uncle, moved to America when I was five, has been living there for nearly ten years. met us at the airport. I was when I set my foot on the land of America. In the days, we visited some places of interest and took photos in front of the Statue of Liberty. We all enjoyed visiting the Museum of Natural History it enriched our knowledge . For me, this is one of the most rewarding trips I have ever made in my life and I am looking forward to there again.

　　难项分析：

　　第一处：were→was　考查主谓一致。主语后接as well as引导的短语时，谓语动词的数由前面的主语来决定。故were改为was。

　　第四处：exciting→excited　考查形容词。此处指人内心的感受，所以用­ed结尾的形容词。故exciting改为excited。

　　第九处：which→that　考查定语从句的引导词。先行词前由形容词最高级修饰，关系词只能用that不能用which。
