要详细讲解!

1. for up to, up to 表示达到多少多少程度/数量,for接一段时间表示动作或状态的延续
2. condition另外有表示“健康,健康的状态”,under the condition表示状态良好,其他的麻烦自己查找意思吧
3.前面用完成时态,表示离开有一段时间了,用ages,表示几年,for short表示“简称”,for good 表示“永久地,一劳永逸地”,for fear 表示“以免……”
4.on demand, 表示“在需求时,一经需求”,其他的没用法
5.over, jump over表示“从……上面跳过”,同样是上面,on 是有接触的,会扎到小PP,其他的动作不是那么能完成跳过的难度,恐怕还是要被咬到。
