Perhaps the most famous theory, the study of body movement, was suggested by Professor Ray Birdwhistell. He believes that physical appearance is often culturally programmed. In other words, we learn our looks—we are not born with them. A baby has generally informed face features. A baby, according to Birdwhistell, learns where to set the eyebrows by looking at those around-family and friends. This helps explain why the people of some areas of the United States look so much alike, new Englanders or Southerners have certain common face features that cannot be explained by genetics(遗传学). The exact shape of the mouth is not set at birth, it is learned after. In fact, the final mouth shape is not formed until well after new teeth are set. For many, this can be well into grown-ups. A husband and wife together for a long time often come to look alike. We learn our looks from those around us. This is perhaps why in a single country area where people smile more than those in other areas. In the United States, for example, the South is the part of the country where the people smile most frequently. In New England they smile less, and in the western part of New York State still less. Many southerners find cities such as New York cold and unfriendly, partly because people on Madison Avenue smile less than people on Peachtree Street in Atlanta. Georgia. People in Atlanta, Georgia. People in largely populated areas also smile and greet each other in public less than people in small towns do.

Ray Birdwhistell believes that physical appearance ____.

Electronic waste, or e-waste, refers to electronic products that are no longer usable. This can include TVs, cell phones and computers and other office electronics, electronic toys and videos machines. Today, the average turnover（更换）rate for a computer in the United States is every two years, according to the environmental group, Greenpeace.

The group's Dai Yun says e-waste is a global problem. "The electronic industry is one of the fastest growing industries in the world. The high speed of growth in this industry means more and more electronic products are being wasted and thrown away. If no one decides to retrieve the old products and process them properly, the electronic waste will sweep over the earth like the huge wave behind me and pollute the Earth seriously."

Greenpeace works out that 20 to 50 million tons of e-waste are produced globally each year. The components（部件）in many electronic products contain harmful chemicals that pollute ground water and the environment.

At present , the U.S. has no federal law for the disposal (处理) of e-waste although a few states have e-waste recycling programs in place, but there is no law. The U.S. exports much of its e-waste to third world countries, such as India and China, where workers took apart computers for valuable parts, hoping to sell them for money. But harmful wastes expert, Dr. Bakul Rao, says that's a dangerous practice. "From now on, the recyclers are not very educated. All they know is they can retrieve copper or gold out of it. So, the easiest way to do that is leach (过滤) it out in an acid or burn it off to retrieve it. So, that's where they don't know how to deal with it, neither do they have any health systems in place. So, their exposure is more."

A. look into   B. take apart   C. get back   D. throw away
