  Lesson 25


  1.at the time of...



  at the time of...意思是"在......时候",后面常接名词或名词词组。例如


  He was very brave at the time of danger.


  2.fall off fall off意思为"从......掉/摔下来",off可用作介词,后接名词、代词等,也可用作副词。例如


  Ripe apples are beginning to fall off the trees.成熟的苹果开始从树上落下来。


  2.I felt the floor move.


  feel这里用作及物动词,意思是"感到",后面接复合宾语,即宾语+宾语补足语。宾语补足语通常是不带to的动词不定式或现在分词,结构是:feel...do/doing。例如


  I felt my heart beating fast.我感到我的心正在快速跳动。


  We both felt the desk shake just now.我们都感到刚才桌子摇晃了一下。


  3.I watched all the glasses fall off.


  这里watch用作及物动词,意思是"观察,观看",后接复合宾语,复合宾语中的宾语补足语通常是不带to的不定式或现在分词,意思稍有区别。watch sb./sth.do意思是"观看某人/某事做了......",表示看到事情发生的全部过程,而watch sb./sth.doing意思是"观看某人/某事正在做......",表示看到事情正在发生的情形,并不一定指看到全过程。例如


  We watched the sun rise from the east.


  She watched her son swimming in the swimming pool.


  4.Carl, what does"quake" mean, as in the word"earthˉquake"?卡尔,"earthquake"里的"quake"是什么意思?as in the word"earthquake"是省略句,原句应为as it is in the word earthquake。as是连词,意思是"如","像"。


  as可以作连词、介词和关系代词。现将as的用法小结如下


  1)作连词


  ①作"当......时候"解,引导时间状语从句,强调两个动作同时发生,或某事一发生,另一件事也立即发生。例如


  They were singing as they were walking home.回家时他们边走边唱。


  I startled as he opened the door.他一开门,我吓了一跳。


  ②作"因为"解,引导原因状语从句。例如


  I must stop writing now,as I have a lot of homework to do.我现在必须停笔了,因为我有许多作业要做。


  ③作"如/像"解,引导方式状语从句或比较状语从句。


  You should do as the teacher tells you to.你应当像老师告诉你的那样去做。


  The weather was not so wet as it is today.那天的天气不像今天这么潮湿。


  2)作介词,作"作为"解。例如


  He was famous as a pop singer.作为流行歌星,他很有名。


  3)作关系代词,在the same as和as follows这类结构中,as是关系代词。

  4.cut off


  cut off意思是"切断,切去"。off用作副词,如果动词宾语是代词,则必须置于off前。如果是名词则可以放在off前,也可以放在off后。例如: He cut off a small piece of cake and gave it to me.他切下一小片蛋糕并递给了我。

  6.stay up stay up意思是"保持,持续(在高处)",up是副词,意思为"向上"。本课中 stay up的意思是"(房子、建筑物经历过地震后仍然)站立着"。另外它还有"熬夜"的意思。例如

  这里times意思是"倍,倍数",通常"两倍"用twice,三倍或三倍以上用times。这里ten times表示是"(原数)的十倍"或"增加到十倍"。英语中表示倍数的句型有
