    Do you have an English name? I have noticed (注意到) one thing in China: lots of people have uncommon(不常见) English names.

    One of my Chinese friends calls herself Big Bird, like the character(角色) from the children's TV show Sesame Street(《芝麻街》). Another one of my friends is an English teacher. She had students with the names like Tomato and Potato. There were also two girls named Echo. Before I came to China, I had never met anyone with these names.

    People choose these strange names for different reasons. Sometimes they copy the names from someone famous. Other times, they want names that have the same meaning as their Chinese name.

    But having an uncommon English name isn't a big deal, is it? It can be fun sometimes. I once heard about a girl named Shmily. It stands for “see how much I love you”. It is my favorite strange English name.

赴戍登程口占示家人

林则徐

力微任重久神疲，再竭衰庸定不支。

苟利国家生死以，岂因祸福避趋之。

谪居正是君恩厚，养拙刚于戍卒宜。

戏与山妻谈故事，试吟断送老头皮^①。

【注】①宋真宗闻隐者杨朴能诗，召对问：“此来有人作诗送卿否？”对曰：臣妻有一首，云“更休落魄耽怀酒，且莫猖狂爱咏诗。今日捉将官里去，这回断送老头皮”。上大笑，放还山。山妻：对自己妻子的谦称。故事：旧事，典故。

某同学欲乘火车从恩施到宜昌，他注意到候车大厅的运行时刻表如表：

车次	站次	站名	到达时间	开车时间	停留	里程
K50	1	恩施	始发站	15：20	0分	0
	2	建始	15：49	15：52	3分	35
	3	巴东	16：32	16：35	3分	101
	4	宜昌东	17：53	18：12	19分	214

根据列车运行时刻表解答下列问题（保留整数）：

（1）K50次列车由建始到宜昌东需要多长时间？

（2）K50次列车由建始驶往巴东的平均速度为多少km/h？

（3）中途K50次列车以36km/h的速度，用了3min完全穿过长度为1600m的一个隧道，求这列火车的长度是多少？
