　　3. Read it again and find out the difficulties.

　　（1）two weeks ago意为“两周前”。“一段时间+ago” 表示“多长时间之前”，是表达过去的时间状语，常与一般过去时连用。

　　I finished （finish） the work three days ago.

　　三天前我完成了这项工作。

　　（2）There we put up our tents and made a fire to keep us warm and cook food on.

　　①短语：搭帐篷 put up tents　生火 make a fire

　　使我们暖和 keep us warm　在（火）上煮食物 cook food on （the fire）

　　②to keep...and cook...是动词不定式短语作目的状语，keep与cook是并列的。

　　③“keep sb. +adj.”意为“使某人保持某种状态”，keep us warm意为“使我们暖和”。

　　④put的过去式为put，made是make的过去式。

　　（3）But I was so tired that I went to sleep early.

　　I was so scared that I couldn’t move.

　　so...that...表示“如此……以至于……”。that后必须是句子，表示某一结果，如果这个结果是否定的，且句子的主语与前面句子的主语一致，则可与too...to...结构进行同义转换。

　　I was so scared that I couldn’t move. = I was too scared to move.

　　The game is so interesting that I don’t want to stop playing it. 这个游戏如此有趣，以至于我不想停下来。

　　（4）surprise的用法：

　　①作名词，意为“惊奇；惊讶；惊喜”，常用短语有：in surprise（惊奇地），get a surprise（吃惊），to one’s surprise  （使某人惊讶的是），give...a surprise（给……一个惊喜）。

　　②作动词，意为“使……惊奇/惊讶”。surprise的形容词形式为surprising（令人惊奇的），surprised（吃惊的）。

　　I got a surprise when I met him again.

　　当我再次见到他时我吃了一惊。

　　They were surprised to hear the surprising news about me but I didn’t want to surprise them. （surprise）

　　听到有关我的这则令人吃惊的消息，他们感到很惊讶，但是我并不想让他们诧异。

　　（5）英语中的感官动词，如see，hear，feel等，后面可以接doing，作宾语补足语，表示“看见/听见/觉得某人或某物正在做某事”。

　　I heard someone singing （sing） in the next room when I passed by yesterday.

　　我昨天经过时听到有人正在隔壁房间里唱歌。

　　（6）wake up意为“唤醒；叫醒”，为及物动词短语，是由“动词+副词”构成的短语。后面可以跟名词或人称代词作宾语。宾语是名词时，可以放在wake和up的中间或后面。如果宾语是人称代词，应放在wake和up的中间。
