德国古城海德堡，对我来说早已不是一个陌生的地方了，去年我们一家刚去那儿玩过。那里碧绿的河水、高耸的青山以及矗立在半山腰的古堡，也早已深深地印在了我的脑海里。7月7日，我又一次来到了那青山脚下、绿水河畔，带刚从故乡苏州来德国才一周的外公外婆玩这座古城。那天一? The old German city of Heidelberg was no longer a strange place for me. Last year our family had just played there. The green rivers, the towering hills, and the castles that stand on the hillside have also been deeply imprinted in my mind. On July 7th, I once again came to the bank of the Qingshan River, on the bank of the green river, and took the grandfather’s grandmother who had just come to Germany from his hometown Suzhou for a week to play the ancient city. That day?
