1、gather, collect

gather为“收集，聚集”，可用于人或事物，指把零散的人或事物聚集起来。collect为“收集，采集”，只能用于事物，不能用于人。当指一般性的收集，即把分散的事物集合在一起时，与gather同义，可以相互换用。如gather/collect flowers（采花），gather/collect fallen leaves(聚拢落叶)。它另可指为某种目的而有选择地收集，着重计划性和选择性。

试比较：gather books 把书聚集在一起 -- collect books 收集藏书gather money 攒钱 -- collect money 筹募资金gather stamps 把邮票集中在一起 -- collect stamps 集邮gather thoughts 集中思想 -- collect thoughts 组织思想　

2、gaze, glare, stare

3、get in, get on
