Service on the 102-km high-speed railway between Shenzhen and Guangzhou started on December 26, 2011. A non-stop trip between the Guangzhou South Station and the Shenzhen North Station takes 35 minutes at full speed.

    The train runs at the highest speed of 300 km per hour. All 36 pairs of trains run every day. A one-way first-class ticket costs 100 yuan. A second-class one costs 75 yuan, 5 yuan cheaper than a second-class ticket on the slower line.

    A high-speed train has 556 seats, including 16 seats in the VIP rooms and 50 in the first-class carriage (车厢). It offers more advanced facilities (先进的设施). For example, the seats are more comfortable, there are toilets for the disabled (残疾人), and there are power outlets (电源插座) in the first-class carriage.

    The high-speed service between Guangzhou and Shenzhen will be a convenient choice for many people. “I won't need to travel to the Guangzhou East Station to take a train to Shenzhen,” said Wang Yi, who lives in Panyu district in Guangzhou.

    Many people still prefer the slower trains, because the terminals (终点站) of the high-speed trains are far away from the centres of both cities. “I would not like to take a high-speed train to Shenzhen. I live in the centre of Guangzhou. First I have to get to the Guangzhou South Station. It is a waste of time for me,” said Zhang Lu.

回答下列问题．

写作表达。

阅读下面材料，选择感悟最深的一点，自拟题目，写一篇文章。

中国科学院院士薛其坤及其团队，心存高远，脚踏实地，沉浸于量子世界十余载，追求小量子里的大“梦想”。他们坚持不懈，追求极致，发现了量子反常霍尔效应。这是继美国物理学家霍尔于1880年发现反常霍尔效应130多年后，人类首次实现其量子化。

认识薛其坤的人几乎都知道他近乎苦行的生活轨迹。早上7点进实验室，晚上11点才离开，这样的作息时间，他已经坚持了整整20年。在薛其坤看来，“全世界从事实验物理研究并取得重要成就的人，无一例外都是刻苦的。”刻苦是他们团队攻坚克难的第一秘诀。

科学研究的刻苦不是常人所能坚持的。薛其坤认为进入了这个科学世界，应该以苦为乐，这样的坚持是一种享受。他在紧张的工作中体会到的是快乐，而非痛苦。

凭借对科学的好奇心，对工作的热爱，对科研的责任心与担当，对信念的坚守，薛其坤及其团队勇于探索，刻苦钻研，终于向国际科学界“亮剑”。

“把科研工作一步一步做上去，把学生一个一个培养出来，唯有如此才能为实现中华民族伟大复兴的‘中国梦’贡献出自己的力量。”这就是这位科学追梦人如今最朴素的愿望。（摘编自《人民日报》）
