Some heavily polluting factories and construction sites, such as
8、 those owned by the steel giantShougang Group, have been asked to cut production in November and December or be closed.Beijing was the third polluted city in the world at the end of last century, according to the UN.

17、t the important thing.”Crocker s advice may sound a bit strange because it is good to feel good about yourself.Studies show that people with high self-esteem are less likely to be depressed, anxious, shy, orlonely than those with low self-esteem.But, after reviewingabout 18,000 studies on self-estee

32、e Americans, according to a new theory.If proved by DNA evidence, the theory will break long established beliefs about the southerly migration of people who entered America across the Bering Strait, found it empty and occupied it.

33、first true Americans. Theywould be classified to the ranks of escapee, beaten to the New World by Aboriginals (土著人 ) inboats.To a European, this may seem like an academic argument, but to Americans it is a philosophicalquestion about identity, Silvia Gonzales, of Liverpool University said .Her claim
34、s are based on skeletons found in the California Peninsula of Mexico that have skulls quite unlike the broad Mongolian features of Native Americans. These narrow-skulled people havemore in common with southern Asians, Aboriginal Australiansand people of the South PacificRegion.The bones, stored at t
35、he National Museum of Anthropology (人类学 ) in Mexico City, have beencarbon-dated and one is 12,700 years old, which places it several thousand years before the arrivalof people from the North.“ Wethink there were several migration waves into the Americasatdifferent times by differenthuman groups, ”Dr
