Undesrtanding ideas
Sitting back in my seat, I can't quite believe that I’m about to travel along the railway
that many foreign experts claimed was “impossible”. The train has been racing along steadily since it left
Xining. All this time, the song “Sky Railway” has been playing inside my head. The words “railways like
massive dragons are winding among the mountains” seem particularly vivid as I travel across the “roof of the world”.
sitting是动词的现在分词，作方式状语，与逻辑主语I是主动关系
关系代词that引导的定语从句，定语从句还原后为：many foreign experts claimed (that) the railway was impossible. 关系词在定语从句中作主语，不可以省略。
现在完成进行时，表示动作从某一时间开始，一直持续到现在，或者刚刚终止，或者可能仍然要继续下去。 其构成为：主语+助动词（have/has）+been+动词的现在分词+其他成分。
The Chinese have been making paper for two thousand years.(造纸一直在进行，并且会继续下去）
I have been learning English since three years ago.(学英语一直在进行，并且会继续下去）
Undesrtanding ideas
I was one of the people who came from all parts of China to work on this railway. Taking years to complete,
the Qinghai-Tibet Railway is a record of all of our efforts
to overcome the most difficult engineering challenges.
How to protect the delicate ecosystem was among the top concerns.
关系代词who引导的定语从句， 修饰先行词people, 关系词在定语从句中作主语，不可以省略
taking动词的现在分词作状语，与逻辑主语the Qinghai-Tibet Railway是主动关系
overcome the challenges 克服挑战
点拨
非谓语动词作状语时，要看非谓语动词与句子主语之间的逻辑关系，
作状语的动词与句子主语构成主动关系时，要用现在分词形式；
构成被动关系时，要用过去分词形式；
表示目的，常用动词不定式，这时非谓语动词表示的动作与句子谓语动词的时间相比，是将来。
Undesrtanding ideas
The first landmark to catch my eye is the splendid Qingshuihe Bridge, the world's longest bridge built over
permafrost. Look! A group of Tibetan antelopes is moving under the bridge, with some stopping to eat grass
at their leisure. Thirty-three passages have been built under the railway to allow the animals to move safely
and freely in their natural habitat. Wild animals such as these Tibetan antelopes have now been using these
passages for years. They seem totally unaware that we are speeding past at over 100 kilometres an hour.
catch one's eys 吸引某人视线，吸引某人注意
eye-catching adj 因人注目的，耀眼的，明显的
built过去分词作后置定语
with+名词/代词+doing，作状语，表示伴随的状态，some和stopping之间是主动关系
悠闲地
现在完成进行时，表示从过去到目前一直持续并可能继续下去的动作
