    ①太和殿俗称金銮殿，高28米，面积2380多平方米，是故宫最大的殿堂。在湛蓝的天空下，那金黄色的琉璃瓦重檐屋顶，显得格外辉煌。殿檐斗拱、额枋、梁柱，装饰着青蓝点金和贴金彩画。正面是12根红色大圆柱，金琐窗，朱漆门，同台基相互衬映，色彩鲜明，雄伟壮丽。

    ②大殿正中是一个约两米高的朱漆方台，上面安放着金漆雕龙宝座，背后是雕龙屏。方台两旁有六根高大的蟠龙金柱，每根大柱上盘绕着矫健的金龙。仰望殿顶，中央藻井有一条巨大的雕金蟠龙。从龙口里垂下一颗银白色大圆珠，周围环绕着六颗小珠，龙头、宝珠正对着下面的宝座。梁枋间彩画绚丽，有双龙戏珠、单龙翔舞，有行龙、升龙、降龙，多态多姿，龙身周围还衬托着流云火焰。

    ③三大殿建筑在紫禁城的中轴线上，这条线也是北京城的中轴线，向南从午门到天安门延伸到正阳门、永定门，往北从神武门到地安门、鼓楼，全长约八公里。

Sara Savick remembers one special Easter when she was nine years old. Her parents gave her a baby duckling in a yellow basket.

“Mom said later that she bought the little duck because she felt sorry for it，” recalled Sara. The people at the pet store colored the feathers pink for Easter. Sara named the duck Pinky.

Sara's mother really didn't think the baby duck would survive very long. But to her surprise, Pinky grew and got stronger and stronger. Soon, the little duckling was a healthy, hungry duck with white feathers.

“We fed Pinky oatmeal, cooked and uncooked, and small pieces of vegetables，” said Sara. Pinky lived inside the house with Sara and her family. She specially fancied taking baths with Sara. Everyone treated Pinky as a family member.

But just when everything appeared to be perfect, the night of the “talk” came. Sara's Mom and Dad sat her down, explaining that the best thing for Pinky was to live a normal duck life, with other ducks. It was not natural for ducks to live indoors with a family, her father told her. He added Pinky needed to swim in ponds and do all the same things that ducks in the wild do.

Sara started to cry, knowing what was going to happen. Sara's parents decided to take Pinky to a park, which was two miles away. There was a pond with a lot of other ducks. Pinky would have the chance to live a natural life and Sara could still visit her.

The big day came, Sara and her parents put Pinky in a box and drove to the park. Sara said that Pinky did not look happy; maybe Pinky was convinced that she was a human, not a duck.

注意：1）词数应为150左右；

2）请按如下格式作答。

Everyone was sad when they left Pinky at the pond, even Sara's father.

The next morning, when looking out of the kitchen window, Sara couldn't believe her eyes! tightly, tears streaming down her cheeks.
