几个英语问题疑惑点
1.
Ladies and gentlemen,please remain [ seated ]（seat）until the plane has come to a complete stop.
Ladies and gentlemen,please remain [ sitting ]（sit）until the plane has come to a complete stop.
两句用法不同的原因是什么,怎样区别?
2.
翻译句子：
（1）You'd better add up your coins,and see how long you can last.
（2）Words become filled with meaning for us by experience; and the longer we tire,the more certain words bring back to us the happy and sad events of our past.

答案

sit用主动语态,sb.sit
seat用被动语态,sb.be seated
表达的意思都是一样的,就是某人坐
remain和be在语法结构上是完全等同的,都是系动词.
于是作表语表达某一状态时sit用现在分词,seat用过去分词

（1）你最好把你的硬币都加起来,看看能维持（生活）多久.
（2）通过（我们的）经验,文字对我们变得有意义；并且使用越久,文字能越明确地勾起我们过去的开心事或伤心事.
