English Question
Mainframe computers were very large indeed,often occupying whole air-conditioned rooms,employing full-time technicians and run on specially-written software.
Question:1.为什么用run不用running?
2.为什么specially-written要用-连接起来,write为什么用过去分词?
▼优质解答
答案和解析
1:run on是一个固定的词组,表示"连续不间断"
2:英语里的有这样的表达习惯
比如hand-made:手工制造
为强调是被动,被怎么怎么样,所以用过去分词
