2、do the trick 做成功;达到理想的结果

——I’ve been trying to get the furnace started, but I can’t find the right switch. (我尽力想让炉子燃起来，可不知道该按哪个键。)

——Here, I believe this one in the back will do the trick. (这里，我相信后面按这个键，可以让炉子燃起来。)

例：

If your friends are too busy to meet for lunch, a short phone call can do the trick要是你的朋友太忙而无法一起吃午饭，一个简短的电话也能起到很好的效果。

3、drag one's feet 行动缓慢;磨磨蹭蹭不情愿

——How’s Bob coming along on his dissertation proposal? (Bob的论文计划进展地怎么样了?)

——He’s really been dragging his feet. (他很磨蹭的。)

例如：一个百货公司的雇员正在罢工，要求增加工资。这个公司的经理说：

The union is dragging its feet on agreeing to a settlement. They think the company is getting desperate to get people back to work because Christmas is coming and that's our busiest time of year.

工会拖拖拉拉地不肯就解决方案达成协议。他们认为，公司一定会迫不及待地要雇员回去工作，因为圣诞节快来了，这是我们一年最忙的时候。
