As an Alaskan fisherman, Timothy June, 54, used to think that he was safe from industrial pollutants (污染物)at his home in Haines—a town with a population of 2,400 people and 4,000 eagles, with 8 million acres of protected wild land nearby. But in early 2007, June agreed to take part in a【C1】______ of 35 Americans from seven states. It was a biomonitoring project, in which people’s blood and urine (尿)were tested for【C2】______ of chemicals—in this case, three potentially dangerous classes of compounds found in common household【C3】______. like face cream, tin cans, and shower curtains. The results—【C4】______ in November in a report called “Is It in Us?” by an environmental group—were rather worrying. Every one of the participants, 【C5】______ from an Illinois state senator to a Massachusetts minister, tested positive for all three classes of pollutants. And while the【C6】______ presence of these chemicals does not【C7】______ indicate a health risk, the fact that typical Americans carry these chemicals at all【C8】______ June and his fellow participants. Clearly, there are chemicals in our bodies that don’t【C9】______ there. A large, ongoing study conducted by the Centers for Disease Control and Prevention has found 148 chemicals in Americans of all ages. And in 2005, die Environmental Working Group found an【C10】______ of 200 chemicals in the blood
of 10 new-borns. “Our babies are being born pre-polluted,”says Sharyle Patton of Commonweal, which cosponsored “Is it in Us?”“This is going to be the next big environmental issue after climate change.”A) analyses I) productsB) average J) rangingC) belong K) releasedD) demonstrated L) shockedE) excess M) simpleF) extending N) surveyG) habitually O) tracesH) necessarily

For decades, Americans have taken for granted the United States’ leadership position in the development of new technologies. The innovations (创新)that resulted from research and development during World War II and afterwards were【C1】______ to the prosperity of the nation in the second half of the 20th century. Those innovations, upon which virtually all aspects of【C2】______ society now depend, were possible because the United States then【C3】______ the world in mathematics and science education. Today, however, despite increasing demand for workers with strong skills in mathematics and science, the【C4】______ of degrees awarded in science, math, and engineering are decreasing. The decline in degree production in what are called the STEM disciplines (science, technology, engineering, and math)seems to be【C5】______ related to the comparatively weak performance by US schoolchildren on international assessments of math and science. Many students entering college have weak skills in mathematics. According to the 2005 report of the Business-Higher Education Forum, 22 percent of college freshmen must take remedial (补习的) math【C6】______, and less than half of the students who plan to major in science or engineering【C7】______ complete a major in those fields. The result has been a decrease in the number of American college graduates who have the skills, 【C8】______ in mathematics, to power a workforce that can keep the country at the forefront (前沿) of innovation and maintain its standard of living. With the【C9】______ performance of American students in math and science has come increased competition from students from other countries that have strongly supported education in these areas. Many more students earn【C10】______ in the STEM disciplines in developing countries, than in the United States.A) accelerating I) especiallyB) actually J) futureC) closely K)ledD) contemporary L)metE) courses M) proceduresF) critical N) proportionsG) declining O) spheresH) degrees 21．【C1】
