Mainframe computers were very large indeed,often occupying whole air-conditioned rooms,employing full-time technicians and run on specially-writtten software.
这个句子里occupying employing run 都做Mainframe的定语..
为什么前两个是现在分词..run是过去分词..
他们怎么看出来是并列的啊..
如果run和were并列..那么occupy和employ也可以看作是和were并列的了么

因为RUN A MAINFRAME COMPUTER的结构里 MAINFRAME COM.是被RUN.
是宾语.而前面两个 MAINFRAME COMPUTER OCCUPIES WHOLE() ROOMS.
MAINFRAME COMPUTER EMPLOY FULL-TIME TECHNICIANS里都是做主语.
用ING形式.
