(当我看到玛丽的时候,她正在吃饭.) while表示“在的时候”、“在期间”。while后面必须是表示动作或状态的延续性动词，例如：The weather was fine while we were in Beijing .(当我们在北京的时候天气很好.)所以, when可指时间点，又可指时间段，从句中可用延续性动词，也可用非延续性动词。while总是指一个时间段，从句中必须用延续性动词。 2. Not everyone will remember who killed him, but they can remember what they were doing when they heard that he got killed. 1) not everyone并不是每一个人, 在英语中all, both, every, everyone, everything, everybody, everywhere等与否定词not, no连用时，表示的是部分否定，而非全部否定。例如：Not every student goes to the farm on Sunday. 并不是每一个学生星期天都去农场。若要表示全部否定，则应用相应得表示部分否定的否定词。Allnone, both-neither, everyno, everyoneno one（nobody）, everythingnothing, everywherenowhere等。以上的四个例句要表示全部否定应分别为：No student goes to the farm on Sunday. 没有学生星期天去农场。 2) get killed 被杀 例如：We dont know who got killed. 我们不知道谁被杀了。 3. I had trouble thinking clearly after that because I was very afraid. 1) have trouble doing 做某事有困难，与此用法一致的, have problem doing , have difficulty doing. 例如: We have trouble learning English. 我们学习英语有困难。 2) be afraid 害怕，be afraid of sth. 害怕做某事，be afraid to do sth. 害怕去做某事。例如: Im afraid of the snakes. 我害怕蛇。 4. I played the song without any mistakes. . without any mistakes 没有任何错误，without 的用法： 1) (表否定)没有，无，不需。例如：We got there without any trouble. 我们到了那儿，一路上没遇到任何麻烦。 2) (用在no, not, never等否定副词之后，强调肯定)没有不，没有则不能，每必定。如：The old man cannot walk without a stick. 那位老先生离开手杖就走不了路。 3) (与-ing形式连用)不，无，没。例如：She entered the room without knocking. 她没敲门就进了房间。 4) (表条件)若无，若非。例如：I dont like to go to a country without knowing something of the language. 我要是不懂得一点那个国家的语言，就不想到那个国家去。【学案导学】一、写出下面的短语和句子。1. 首先_2. 讲真话_ 3. 被杀_4. 做事有困难_5. walk home _ 6. older brother_ 7. stop breathing_8. 罗伯特的父母亲听到这个消息很震惊。 .9. 不是每一个人都记得是谁杀死了他。 .10.
