在寒假里，我和妈妈、姐姐、四姨一起去了“玉渊潭冰雪节”游玩。在玩的过程中，我和姐姐是状况百出，笑话不断，妈妈和四姨也想两个天真的孩子一样同我和姐姐一起玩了起来，甚至，比我们玩得还高兴呢！
记得这是在一个星期六的早晨，大约10点左右。我们买了票，租了一个金黄色的、有一些零星搭配的“雪圈”，就开始玩了起来。我先坐在里面，姐姐拉着我，妈妈和四姨跟着我们。我们每个人脸上都面带笑容。就冲这，我相信这会是
一次很高兴的游览。
首先，我滑了一个5米多高的斜雪坡。不同的是，我是趴在雪圈上滑下来的，并不是坐上去，然后滑下来的。我虽然当时感到了一些恐惧，但还是面带笑容地、勇敢地滑了下来。后来，我感到很刺激！然后姐姐、妈妈、四姨又一个一个滑了下来，同样，她们也感到了这种前所未有的刺激。
接着，姐姐拉着我去了一个小雪坡。这个小雪坡还不到1米高，只不过，多了一个小坡。看到这，我不禁有点失望。于是，我回过头，问姐姐：“这好玩吗？会有那个刺激吗？”可姐姐却说：“你可别小看了这个雪坡。其实，这个雪坡是一大玩点。你看，当“雪圈”经过这个小雪坡的时候，会颠一下。虽然没有那个刺激，但也挺好玩的。”听到这，我连忙说：“姐姐，你推我下去吧！”姐姐说：“好吧！”边说着，就把我推了下去。开始，没什么感觉，突然一下子，颠了一下，吓了我一大跳。你别说，还真好玩。于是，她们一个个地滑了下来。这个项目，我们就在欢声笑语中度过了。
接下来，我们又玩了许多有趣、刺激的项目。在这里，我就不一一介绍了。
最后，我们观赏了几位来自南极的“小明星”—企鹅。它们一个个都趾高气昂，拼命展示着它们自己的风采和与众不同的一面。而我们作为游客，用看电影明星一样眼神欣赏着这些可爱的小企鹅。这可把小企鹅乐坏了，你看，他们正在“呵呵呵”地笑呢。
不知不觉，1个小时过去了，我们也该从欢声笑语中走出来了。眼看这次的游览就要结束了。马上要离开的我们还有点依依不舍。可是，有什么办法呢？我们只好从公园里一步一步地走向大门。“再见了，玉渊潭冰雪节！”

Dear Li Ming
How is everything going? I heard that you are coming to Harbin this winner.
I am gald that we can get together soon. Here is some introduction, you can learn more about this city.
Harbin, the capital city of Heilongjiang Province, is a thriving industrial center in northeastern
China. Nicknamed “Ice City”, it attracts both local residents, as well
as visitors from around China and abroad, for its International Ice and
Snow Festival held annually from January 5 to February 5. The highlight of the festival is an impressive artistic ice lantern
exhibition featuring ice and snow carvings displayed in Zhaolin Park
and on the frozen Songhua River.
The fanciful ice sculptures are crafted in the shapes of animals,
plants, buildings or legendary figures. Many world famous monuments
including cathedrals, the pyramids, the Potala Palace and the Great Wall
are meticulously carved out of ice, sometimes in spectacularly giant
sizes! Lots of the sculptures are illuminated from inside with colorful
lights and are especially stunning when seen at night.
Hope you can see it soon.
Yours,
Wang Lin
