look

1.Look at that boy jump和Look at that boy jumping都可以说。第一句比第二句更着重在“跳”。

2.He looks like a monk和The tree looks like an elm等句子里的like不可改作as。

Jack looks like a monk跟Jack looks a monk意思相仿。但look like往往有“好像…而实际不是”的含意。

3.look forward to（盼望）里的to是介词，后面接名词或动名词。例如：I am looking forward to his visit. 和I am looking forward to seeing him. 不可说I am looking forward to see him。

4.look over（over是介词）the account和look the account over（over是副词）都作“查阅账目”解。

5.the look of him是“他的面貌”，就是his looks。his look是“他的一看（的状态）”。
