worry

1.worry统指“忧虑”，a worry是“一件忧虑的事”，worries是“多件忧虑的事”。

2.下面各句都可以说：

• Don't worry about that.
• Don't worry yourself about that.
• Don't let that worry you.
• Don't be worried about that.

第二句有“别为了那件事而庸人自扰”的意思。第四句最不普通。

3.worry（动词）可以作“不断地请求”解。例如：The boy was always worrying me to take him to the zoo. 和The boy worried his mother to buy a pop-gun. 把to take和to buy改作into taking和into buying也可以，但比较不普通。
