and shortly after i moved here in January,2002,to begin teaching at Tsinghua University,i found several opportunities to go to Hong Kong,Macau and parts of Guangdong.
请问:
句中的to begin teaching at Tsinghua University,作什么成分?
还有,

请问:

问题1:
and shortly after i moved here in January, 2002, to begin teaching at Tsinghua University, i found several opportunities to go to Hong Kong, Macau and parts of Guangdong.
就在2002年1月,我搬到这不久,正要开始在清华任教,我发现了几次机会可以去香港,葡萄牙和广东一些地方.
请问:
句中的to begin teaching at Tsinghua University,作什么成分?
我个人认为这是个省略句,省略了时间状语.全句应是When i am going to begin ...
还有,问题2:
For example, on my first trip to China in mid-2001, i visited three of the largest cities, Beijing,Shanghai and Chongqing, which were fascinating experiences-so fascnating that i decided to quit my job at home and move to China for a few yeaars. In less than a year i had done so.
比如,在2001年中旬的第一次中国之旅,我游览了三大城市,北京,上海和重庆,真是醉人的体验－－太迷人了以致于我曾决定放弃我在家的工作,搬到中国呆上几年.至少一年我曾那样想过.
请问:
句中的过去完成部分,为什么不能用现在完成时?
如果用现在完成时, 也就是说对现在造成了影响,就是说现在还有那样的想法.
如果是用过去完成时,就是说那种想法只持续了一年,后来就不那么想了.
可见,意思截然相反,所以不应替换.

answer one:是目的状语丛句
answer two:因为所描述的事情是在过去已经完成，所以用过去完成式。而现在完成式用于过去发生，截至目前已经完成的事情。

Q1:做补语吧... 补充那个here... 就是宾语...
Q2:因为是发生在过去的过去啊...
