介词形式，被动意义
介词under短语(Book 2 Unit 4 P64
Ex1)
This new railway is still
under construction. 这条新铁路仍在建设中。
本句中的under
construction “正在建设中”。介词under构成的短语，如果它的宾语是表示动作的名词，通常含有被动意义，意为“在……过程中”。它可改换为被动语态。但介词结构使句子言简意赅，避免过多地使用被动语态。这种介词短语在句中常作表语，也可作补足语或定语。例如：
Your suggestion is still under discussion.
你的建议正在讨论中。

arrest for stealing.
据说他由于偷窃被捕了。
