with open arms, with open hands
with open arms的意思是“热情地”, with open hands则是“花钱大手大脚地”的意思。例如:

be open, be opened
be open表示“正开着”这一状态, open是形容词; be opened指“被打开”这一动作, opened是动词open的过去分词。试比较:
The door is open.
门是开着的。

门被强行打开了。
open, begin
这两个动词都可表示“开始”，但open还可表示“开业”，而begin无此义。
open, hold
这两个词的词义相近,但并不相同。hold指“举行”会议、会谈、比赛等; 而open则指为大楼等举行揭幕典礼或宣布会议、运动会等开幕。例如:
They decided to hold a meeting next Tuesday.他们决定下星期二举行一次会议。
The exhibition will open the day after tomorrow.展览会将在后天开幕。
open, unfold
这两个词都有“打开”的意思,它们的区别在于：open是把原来封起来的或合起来的东西打开或揭开; 而unfold则是指把原来包起来或卷起来的东西摊开。试比较:

请把信封拆开,让我读一读这封信。
