Passage 2

Questions 6 to 10 are based on the following passage:
Nonverbal (非语言的) communication has to do with gestures, movements and close-ness of two people when they are talking. (78) The scientists say that those gestures, movements and so on have meaning which words do not carry.
For example, the body distance between two speakers can be important. North Ameri-cans often complain that South Americans are unfriendly because they tend to stand close to the North American when speaking, while the South American often consider the North American to be "cold" or "distant" because he keeps a greater distance between himself and the person he is speaking to. The "eye contact" provides another example of what we are calling nonverbal communication. Scientists have observed that there is more eye contact between people who like each other than there is between people who don’t like each other.
(79) The length of time that the person whom you are speaking to looks at your eyes indi-cates the amount of interest he has in the things you are talking about.
On the other hand, too long a gaze can make people uncomfortable. The eyes apparent-ly play a great part in nonverbal communication. Genuine warmth or interest, shyness or confidence can often be seen in the eyes. We do not always consider a smile to bea sign of friendliness. Someone, who is always smiling, and with little apparent reasons, often makes us uneasy.

According to the passage, nonverbal communication______.

A.is a method often used by people who cannot speak

B.can tell something that words cannot

C.can be used to talk with people who cannot bear

D.is less used than words
