英语句中的省略句问题
1:in my opinion,life in the twenty-first century is much easier than it used to be、这句to be是省略了什么啊?
2:i do not tell him the news、
oh,you ought to have.这里have指什么、直接you ought to(tell him the news)把括号里的省了不就行了?

1. life in the twenty-first century is much easier than (life which) it used to be.肯定是life与life比嘛.in the twenty-first century 修饰限制说明是现在的生活;定语从句which it used to be修饰限制,说明是...袄、明白了、should have done表示本应该做却没做、needn’d have done表示不应该做、但做了、是吧?谢谢了、
