look是个常用词,也是中考高频词汇之一。其用法有:
  一、用作不及物动词,意为“看、望、瞧”
  1. 单独使用时,后不跟介词。如:

  Look before you leap.三思而后行。
  2. at连用。如:
  The teacher is looking seriously at us.老师正严肃地看着我们。
  Look at these pictures. How beautiful they are!看着这些画,它们是多么漂亮啊!
  3. 和其它某些介词或副词连用,构成固定短语。
⑴look after照看、照料(相当于take care of);⑵look for寻找;⑶look around/about 四下环顾、到处寻找;⑷look back on回想、回顾;⑸look down on看不起⑹look forward to 盼望(其中to为介词,其后需接名词、v-ing形式);⑺look into朝……里面看;⑻look on...as把……看作;⑼look out当心;⑽ look over仔细检查、翻阅;⑾ look through浏览、仔细检查、看穿;⑿ look up抬头看、找出、查(字典等)。如:

If there are words you don’t understand, look them up in the dictionary.如果你有不认识的单词可以查词典。
  
   二、用作连系动词,意为“看起来”
1. 后跟形容词。如:
You look well/fine/healthy.你看起来很健康。

2. 后跟介词短语等。如:

三、用作及物动词,意为看、瞧、打量”。如:

五、易混短语或结构辨析
1. look/see/watch与“看”
本组三个动词都可以表示“看”,但具体“看法”不同:
⑴look表示“看”时,多用作不及物动词,侧重看的动作或提醒注意;look at表示要看的具体内容。如:
She looked but saw nothing.她看了看,但什么也没看见。
⑵see强调“看见”这一结果,多用作及物动词。如:
I often see her walk near the river.我经常看见她在河边散步。
⑶watch是“观看、观察”的意思,强调看的过程,一般用于观看比赛、电视等。如:
I like to watch a football match.我喜欢看足球赛。
He often watches TV on Sunday.他星期天经常看电视。
注意:Let me see.(让我看一看/想一想。)I see.(我明白了。)为习惯用语。
2. look for/ find / find out与“找”
这三个词都有“找”的意思,但具体“找法”有别:
⑴look for意为“寻找”,是有目的地找,强调“寻找”这一动作,未说明是否能找到,是延续性动词。如:
—What are you looking for?你在找什么?
—I'm looking for my bike.我在找我的自行车。
⑵find意为“找到”、“发现”,强调“找”的结果,是终止性动词,其宾语往往是某个丢失的东西或人。如:
—Did you find Li Ming yesterday?你昨天找到李明了吗?
—No, we looked for him everywhere,but didn't find him.没有。我们到处找了,但没有找到他。
⑶find out着重表示通过理解、分析、思考、询问等“弄清楚”、“查明”一件事情,其后的宾语常常是某个情况、事实。如:
Please find out when the train leaves.请查一下火车什么时候离站。
Please find out whose ruler it is.请查明这是谁的尺子。
