2--In the past fifty years, China's pharmaceutical industry has grown from nothing into a booming industry. When the PRC was established in 1949, China's basic pharmaceutical industries were very weak.
 
1--The entire pharmaceutical industry?
 
2--Yes, the entire pharmaceutical industry was quite weak at the 1950s.
 
1--So in the last 50 years it has developed.
 
2--Yes, and now China has achieved an important position in the world market as a supplier of raw materials for pharmaceuticals.
 
1--What do you mean?
 
2--I mean that many multi national companies depend on China for raw materials, and China has cornered about 30% of the market share for pharmaceutical chemicals.
 
1--It seems like in the past 50 years China's pharmaceutical market has opened to the world.
 
2--Not exactly. In the first thirty years, China's economy was not open to Western countries. But since the 1980's, in the last twenty years, China's international trade has taken off.

1--中国的医药业怎么样？
2--在过去的50年里，中国的医药业实现了从低潮到繁荣的转变。尽管1949年建国时，中国的医药业还都十分薄弱。
1--你是在说整个医药行业吗？
2--对。50年代时，医药业不大景气。
1--所以，你认为这些发展都要归功于近50年。
2--对。中国的药品原料出口已经在世界上占有很重要的地位。
1--怎么讲？
2--中国是很多跨国公司的原料供应地，而且它的化学药品在世界市场上的份额达30%之多。
1--好像中国的医药市场在过去的50年里一直都是开放的，是吗？
2--是这样的。最初的30年里，步伐比较缓慢；改革开放近20年以来，发展越来越快。
