要点1
look up 查,查找
look up是由动词+副词构成的短语,如果宾语是代词,要放在look与up之间,如果是名词,可放在look up后面,也可以放在look与up之间。
【重点】另外注意动词后加介词构成动介短语,此时,该短语相当于一个及物动词,后面必须加宾语(由名词、代词或动名词充当),且该宾语不能放在动介短语的中间。
May I come into this room? 我可以进到这个房间里来吗?
(come into是动+介短语,宾语this room不能省略。)
【拓展】 与look有关的常用短语:
look out look through
look over look after
look forward to look like
look for look out of
