集装箱主要有哪些状态信息？
参考答案：
集装箱跟踪管理的箱子状态信息，主要用于掌握集装箱使用状况和适用状况，以便提高集装箱的利用率和周转率。集装箱的状态信息主要表现为以下5种情况：
（1）闲置空箱：闲置空箱是指尚未安排运输任务的空箱，也即等待安排运输任务的空箱；
（2）执勤空箱：执勤空箱是指已被安排运输任务的空箱；
（3）进口重箱：进口重箱一般是指刚从船上卸下的装载着进口货物的集装箱；
（4）出口重箱：出口重箱一般是指即将装船出口的装载着出口货物的集装箱；
（5）残损空箱：残损空箱一般是指不能使用的集装箱，也即等待修理或正在修理的空箱。综上所述，尽管集装箱的流通范围及其使用状态复杂多变，但任意一个港口的码头堆场均可以作为主控点。对于任何一个集装箱的跟踪管理无非是掌握上述动态信息与状态信息的各种不同的组合信息而已。

| "Imagine you are walking along the road. Suddenly you fall over and all the passers-by burst into laughter. You feel very 1 and think the world is laughing at you. But in fact, five minutes later, they have 2 it ever happened." The other day when I came across these words in an article, I didn't agree with the 3 . The author thinks the best thing to do in this kind of 4 is to pretend nothing has happened, and so avoid 5 trouble. I admit that we should keep 6 because "Your tears will only remind others of what happened, while your 7 can let them forget it." But this is far from satisfactory. We should do 8 to make things better. I used to be a(n) 9 girl and not very good at maths. Our new maths teacher asked me a question and I still remember how I hung my head in 10 when I couldn't answer it. "If you don't know the answer, just tell me." the teacher said, "If you don't, how can I know 11 you know the answer or not?" All of my classmates burst into laughter. My face turned red but the teacher 12 me to go to the blackboard and 13 what I knew. If I had 14 the words in the article, I would have given up. But I tried my best. And to everyone's 15 , I succeeded! The teacher smiled and said, "Well done! I 16 you could do it!" Since then, I have become active in maths as 17 as in other subjects. I used to think doing maths exercises was a waste of time. But now, I know 18 I do can make things better. Everyone is the 19 of his own fate. If we make mistakes, we should take on an active 20 . Laugh, and the world laughs with you; weep, and you weep alone. | ||||
