speech．

To be under someone's feet means to be troublesome． In other words， you are standing too close to someone and ass getting in their way． Some adults criticize（批评） children for being under foot．

Speaking of children， if someone says their home will soon have the pitter﹣patter of tiny feet， it means the family is expecting a baby! Now， people who are active do not let grass grow under their feet． They are never in one place for very long． People who can think and take action at the same time are said to be able to think on their feet．

Some people appear to have it all． They have money， a good education， good looks， a great family and a large circle of friends． You could say they have the world at their feet． This means whatever they want seems to be there for them．

People who have both feet firmly on the ground are realistic and practical． They are not dreamy． You might say such a person is well grounded． If you are a bad dancer， you might be described as having two left feet． To dance well， it is better to have a right foot and a left foot．

Sam loves skiing． He think that it would be fun to own a ski resort（滑雪场） high in the mountains． But he knows nothing about running a business． So， he decides to get his feet wet． In other words， he wants/to get used to a new situation．

He joins an organization for resort owners and attends their meetings． He travels to ski areas all over the United Sates． This helps Sam get his foot in the door． Having a foot in the door is a starting point． This expression comes from people selling things door﹣to﹣door． They would block the door with her foot so people couldn't close the door on them．
