Hi~
1.Long long ago there lived many mice in an old house.They were free to do__anything__.
应该填anything,不可以填everything
——————口语里面都可以用,但是作为书面语中,anything是只出现在否定句中的~
2.Then __when___the cat comes close,we will hear the bell and run away.答案要填when,不填if
——————————只要猫一来就能听见,when强调“一……就……”而if语气弱很多~
呵呵是老鼠给猫挂铃铛的寓言叭~我也做过哦~
