Another cultural aspect of nonverbal munication is one that you might not think about: space. Every person perceives himself to have a sort of invisible shield surrounding his physical body. When someone es too close, he feels unfortable. When he bumps onto someone, he feels obligated to apologize. But the size of a person‟s “fort zone” depends on his cultural ethnic origin. For example, in casual conversation, many Americans stand about four feet apart. In other words, they like to keep each other “at arm ”,people in Latin or Arab cultures, in contrast, stand very close to each other, and touch each other often. If someone from one of those cultures stands too close to an American while in conversation, the American may feel unfortable and back away. When Americans are talking, they expect others to respond to what they are saying. To Americans, polite conversationalists empathize by displaying expressions of excitement or disgust, shock or sadness. People with a “poker face”, whose emotions are hidden by a deadpan expression, are looked upon with suspicion. Americans also indicate their attentiveness in a conversation by raising their eyebrows, nodding, smiling politely and maintaining good eye contact. Whereas some cultures view direct eye contact as impolite or threatening, Americans see it as a sign of genuineness and honesty. If a person doesn‟t look you in the eye, American might say, you should question his motives—or assume that he doesn‟t like you. Yet with all the concern for eye contact, Americans still consider staring—especially at strangers—to be rude. 21. What the author discussed in the previous section is most probably about .

We all know that DNA has the ability to identify individuals but, because it is inherited, there are also regions of the DNA strand which can relate an individual to his or her family (immediate and extended), tribal group and even an entire population. Molecular Genealogy (宗谱学 ) can use this unique identification provided by the geic markers to link people together into family trees. Pedigrees (家谱 ) based on such geic markers can mean a breakthrough for family trees where information is inplete or missing due to adoption, illegitimacy or lack of records. There are many munities and populations which have lost precious records due to tragic events such as the fire in the Irish courts during Civil War in 1921 or American slaves for whom many records were never kept in the first place. The main objective of the Molecular Genealogy Research Group is to build a database containing over 100,000 DNA samples from individuals all over the world. These individuals will have provided a pedigree chart of at least four generations and a small blood sample. Once the database has enough samples to represent the world geic makeup, it will eventually help in solving many issues regarding genealogies that could not be done by relying only on traditional written records. Theoretically, any individual will someday be able to trace his or her family origins through this database. In the meantime, as the database is being created, molecular genealogy can already verify possible or suspected relationships between individuals. “For example, if two men sharing the same last name believe that they are related, but no written record proves this relationship, we can verify this possibility by collecting a sample of DNA from both and looking for mon markers (in this case we can look primarily at the Y chromosome (染色体 )),” explains Ugo A. Perego, a member of the BYU Molecular Genealogy research team. 26. People in a large area may possess the same DNA thread because . A) DNA is characteristic of a region B) they are beyond doubt of mon ancestry C) DNA strand has the ability to identify individuals D) their unique identification can be provided via DNA 27. The possible research of family trees is based on the fact that . A) geics has achieved a breakthrough B) geic information contained in DNA can be revealed now C) each individual carries a unique record of who he is and how he is related to others D) we can use DNA to prove how distant an individual is to a family, a group or a population 28. The Molecular Genealogy Research Group is building a database for the purpose of . A)。
