                                         。

二、讲述一件令你记忆深刻的事。

【课中案】

一、自主学习：

 Make a note about an event you remember well.

二、质疑解惑：

1. While I was walking home from school, I saw a strange light in the sky.

译为                                         .

以when和while引导的时间状语从句

1）延续性动词指动作可以延续一段时间，而不是瞬间结束。例如：work, study, drink, eat等。

2）非延续性动词指动作极为短暂，瞬间结束。如：start,begin,arrive,jump,go, finish,borrow,knock等。

when表示“当……的时候”。它后面既可跟延续性动词，又可跟非延续性动词，例如：Mary was having dinner when I saw her. (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. 

译为                                         .

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。All—none, both---neither, every—no, everyone—no one（nobody）, everything—nothing, everywhere—nowhere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 don’t 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.

译为                                         .

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: I’m afraid of the snakes. 我害怕蛇。

4. I played the song without any mistakes.

译为                                         .

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 don’t 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。
