(说明不到10点就在车站了）They arrived at the station at ten yesterday.2）在没有明确的时间状语做标志时，谓语动词动作发生的时间先后需依据上下文来判断，先发生的用过去完成时，后发生的用一般过去时Audrey Hepburn had also been a model before she became a Hollywood superstar.3）当两个或两个以上的动作用and或but连接时，按时间顺序只需用一般过去时代替过去完成时；另外在引导的从句中由于这些连词本身已经表示时间的先后，因此也可以用过去时来代替过去完成时He entered the room, turned on the light and read an evening paper.I (had) called her before I left the office.（二）用 should, ought to, had better, have to, and must 提建议1. should 和ought to 用should/ought to 可以表示“劝说”或“督促”， 和must 一样， 但三者语气强弱不同。用ought to则语气上不那么坚定。用should 语气比较肯定一些，说话人的主观信心要强烈一些。用must则在语气上最强烈。I ought to write to him today. We should protect the environment.You must do your homework.2. must 与have to must表示“必须”，侧重于说话人的主观意志。have to 表示“必须”，侧重于客观的需要，含有“不得不”的意味。He must say it in English. (I want him to do.)He has to say it in English. (Because he doesnt know Chinese.) He must move the big box. (I am too busy to help.)He has to move the big box. (Hes got no one to help him.)3. had better (常缩写为d better) ，是一固定词组，表示“最好”，用于表示对别人的劝告、建议或表示一种愿望。had better 后面加动词原形，即 had better do sth.。不论主语是第几人称，句子无论是何种时态，had better的形式不变。有时简略地说成 “better do sth.”。Youd better put on the coat. Its cold outside.had better 的否定形式为had better not do sth. 表示“最好不要做”。Youd better not miss the last bus.Youd better not play on the road. Its dangerous.反意疑问句：You had better get there on time tomorrow,_? You had better not play on the road, _? 对长辈说话时用：It might be better for youIt would be better for you （三）用 why not, why dont youand perhaps提建议Why not?/Why dont you ?这两种句型结构常用于说话人向对方提出一个建议，意思是“为什么不？”；“你为什么不？”Why not?/ Why dont you ? 后面必须跟动词原形。Why not go swimming?=Why dont you go swimming? Why dont you go out for a walk? =Why not go out for a walk?巩固练习：1.My mother was ill. I _ stay at home to look after her. A. mustB. have toC. couldD. can2. _ go shopping with your father?
