1.What were you doing when the UFO arrived?

I was standing in front of the library.（1）in front of …

在……前面，当……的面

in the front of …

（2）过去进行时：表示在过去某一时间内正在进行的动作。过去某一点时间正在进行的动作或某段时间内一直进行的动作。构成：was / were +

doing。过去进行时的标志词：at 8 o’clock last night, this time yesterday 等。注意：一些动词，如see，hear, love, like, know, remember, understand, have等感情、知觉和状态的词，一般不用于进行时。

过去进行时和一般过去时的区别：过去进行时表示过去正在进行的动作，而一般过去时则表示一个完整的动作。

2.I was getting out of the shower.我正洗完澡出来。

“get out”出来，get out of … 从……出来

3.I was walking down Centre Street when a UFO landed.walk down / along 沿着……走。

land“着陆、下降”，动词。take off“起飞”

e.g.The plane landed safely.4.The girl was shopping when the alien got out.While the girl was shopping, the alien got out.when 与while区分：

（1）“当…的时候”，如后面连接的动词为进行时态，则用while多于用when。而when通常与瞬间性动词或延续性不强的动词连用。

（2）如果while前后的动词都是进行时态，while可译为“与此同时”

I was reading while my brother was drawing.（3）当while前后的句子描述的情况相对或相反，while可译为“而”，while更强调并列的对比而非转折。

e.g.I am out-going while my sister is quiet and shy.总之，when表示做某种动作的时间或瞬间，由其引导的时间状语的时态如果是一般过去时，其主句通常要用过去进行时。while表示略长的一段时间，由其引导的时间状语从句用过去进行时，而主句时态根据实际情况而定。

5.I had a very usual experience on Sunday.experience 可数名词，“经历”。an experience一次经历。

6.I followed it to see where it was going, and I was very surprised when it went into a souvenir shop.（1）follow sb./ sth 跟随某人（某事物），follow及物动词，“跟随”。

（2）be surprise“感到吃惊”，主语为人。

e.g.He gave us a big surprise.We’re surprised to hear the news.That movie has a surprising end.7.Isn’t that amazing!太令人惊叹了！

这是感叹句的一种表达形式。如：Aren’t they perfect!

另外还有用how 和what开头的感叹句。例：What a day I had!

8.I saw a cat in a tree.9.It was really scared.be scared “（某人）给吓坏了，害怕了。”近义短语be afraid / frightened.10.He shouted at me.So I stopped climbing.shout at sb.冲某人大叫，shout sth.大叫某事物（shout his name）
