請問watch & look 兩者的解釋有何分別呢?

2 字若解作「看」但有些情況習慣上只用watch (如watch TV) 或
只用 l00k (如 look at me).
以下再分別解釋:
1) watch 是動詞表示看一段比較長的時間,可且可能有監視、督導、觀察
的意思。
例句：The students watched as the doctors performed the operation.
例句：The thief has been watched for 24 hours.
(意思是這賊巳被監視了 24 小時)

2) look 是動詞表示看一短時間, 但是看得留心(專注)
例句：If you looked carefully, you could find it easily.
例句：We looked but saw nothing.
例句：She looked at me and smiled in the party yesterday.

3) watch 和 look 在用法上有很大分別, 兩者都有名詞用法。
例句: I have a good look but I still cannot find my key.
例句：Please call out the watch. (請叫那個巡邏人員來).

4) look 後加 介詞變化很多。
如 look after 解照顧, look back on something 回顧
look down on someone 看不起人.........尚有很多。

5) watch out 就觧作提防。

look 是動詞表示看一短時間, 但是看得留心(專注)
