The next time you attend a social function or go to a place where people meet and interact, take note of the number of people who have adopted the identical gestures and posture of the person with whom they are talking. This "carbon copying" is a means by which one person tells the other that he is in agreement with his ideas and attitudes. By this method, one is non-verbally saying to the other, "As you can see, I think the same as you, so I will copy your posture and gesture."
This unconscious mimicry is quite interesting to observe. Take for example, the two men standing at the hotel bar. They have mirrored each other's gestures and it is reasonable to assume that they are discussing a topic upon which they have the same thoughts and feelings. If one man uncrosses his arms and legs or stands on the other foot, the other will follow, lf one puts his hand in his pocket, the other will copy and this mimicry will continue for as long as the two men are in agreement.
This copying also occurs among good friends or people at the same status level and it is common to see married couples walk, stand, sit and move in identical ways. People who are strangers, however, studiously avoid holding mutual positions. The significance of carbon copying can be one of the most important non-verbal lessons we can learn, for this is one way that others tell us that they agree with us or like us. It is also a way for us to tell others that we like them, by simply copying their gestures.
If an employer wishes to develop an immediate rapport and create a relaxing atmosphere with an employee, he needs to copy the employee's posture to achieve the end. Similarly, an up-and-coming employee may be seen copying his boss' gestures in an attempt to show agreement. Using the knowledge, it is possible to influence a face-to-face encounter by copying the positive gestures and postures of the other person. This has the effect of putting the other person in a receptive and relaxed frame. of mind and he can "see" that you understand his point of view.
What is an appropriate title for this passage?
A.Appropriate Social Behavior.
B.How to Make Gestures.
C.Carbon Copying: Showing Agreement Through Gestures.
D.How to Avoid Carbon Copying.

Escaping a fire is a serious matter. Knowing what to do before a fire breaks out can save a life. For example, people should know the safety measures to take before opening a hall door during a fire. Also, make sure everyone knows how to unlock doors that may be in the escape path. At times, a key is needed to unlock a door from the inside. So, keep the key in the lock, or, you can put the key on a key ring and put it where it can be found easily.
If you live in an apartment, know the ways you can use to get out. Show everyone in the family these routes. Stress the importance of using stairways or fire escapes, not elevators.
From most homes and the lower floors of apartment buildings, escape through windows is possible. Learn the best way of leaving by a window with the least chance of serious injury.
In a home fire, windows are often the only means of escape. The second floor window sill is usually not more than 13 feet from the ground. An average person, hanging by the fingertips, will have a drop of about six to the ground. Of course, it is after to jump a short way than to stay in a burning building. Rolling away from the building when you land.
Windows are also useful when you are waiting for help. Often you'll be able to stay in the room for several minutes if you keep the door closed and the windows open. Keep your head low in the window to be sure you get fresh air rather than smoke that may have leaked into the room.
On a second or third floor, the best windows for escape are those which open onto a roof or balcony. From the roof or balcony, a person can either drop to the ground or await rescuer. Dropping onto cement or pavement might end in injury. Bushes, soft earth, and grass can help to break a fall. A rope ladder should be considered when the drop is too great.
In a town where the fire department acts quickly, it may be best to wait for rescuer. Close the doors and wait by an open window for help. Shout for help. Be sure to close the door before opening a window. Otherwise, smoke and fire may be drawn into the room by the draft.
From most homes you can escape a fire through the ______.
A.attic
B.garage
C.windows
D.balcony
