2014高考英语阅读理解抓分练习题（56）及答案lead deposits, which accumulated in soil and snow during the 1960s and 70s, were primarily the result of leaded gasoline emissions originating in the united states. in the twenty years that the clean air act has mandated unleaded gas use in the united states, the lead accumulation worldwide has decreased significantly.a study published recently in the journal nature shows that air-borne leaded gas emissions from the united states were the leading contributor to the high concentration of lead in the snow in greenland. the new study is a result of the continued research led by dr. charles boutron, an expert on the impact of heavy metals on the environment at the national center for scientific research in france. a study by dr. boutron published in 1991 showed that lead levels in arctic snow were declining.in his new study, dr. boutron found the ratios of the different forms of lead in the leaded gasoline used in the united states were different from the ratios of european, asian and canadian gasolines and thus enabled scientists to differentiate (区分) the lead sources. the dominant lead ratio found in greenland snow matched that found in gasoline from the united states.in a study published in the journal ambio, scientists found that lead levels in soil in the northeastern united states had decreased markedly since the introduction of unleaded gasoline.many scientists had believed that the lead would stay in soil and snow for a longer period.the authors of the ambio study examined samples of the upper layers of soil taken from the same sites of 30 forest floors in new england, new york and pennsylvania in 1980 and in 1990. the forest environment processed and redistributed the lead faster than the scientists had expected.scientists say both studies demonstrate that certain parts of the ecosystem respond rapidly to reductions in atmospheric pollution, but that these findings should not be used as a license to pollute.17.the study published in the journal nature indicates that _.a.the clean air act has not produced the desired resultsb.lead deposits in arctic snow are on the increasec.lead will stay in soil and snow longer than expectedd.the us is the major source of lead pollution in arctic snow18.lead accumulation worldwide decreased significantly after the use of unleaded gas in the us _ .a.was discouragedb.was enforced by lawc.was prohibited by lawd.was introduced19.how did scientists discover the source of lead pollution in greenland?a.by analyzing the data published in journals like nature and ambio.b.by observing the lead accumulations in different parts of the arctic area.c.by studying the chemical elements of soil and snow in northeastern america.d.by comparing the chemical compositions of leaded gasoline used in various countries.20.the authors of the ambio study have found that _.a.forests get rid of lead pollution faster than expectedb.lead accumulations in forests are more difficult to deal withc.lead deposits are widely distributed in the forests of the usd.the upper layers of soil in forests are easily polluted by lead

for a threenight stay at the hotel. this price also includes an eightweek training course on an island. during their stay, guests would see the sunrise 15 times a day and travel around the world every 80 minutes. galactic suite ltds ceo xavier claramunt says the project will put his company in a leading position of a new industry with a huge future ahead of it, and forecasts space travel will become common in the future. “its very normal to think that your children, possibly within 15 years, could spend a weekend in space” he told reuters television.a promising space tourism industry is beginning to take shape with construction in progress in new mexico of spaceport america, the worlds first facility built specifically for passengers. british industrialist richard bransons space tours firm, virgin galactic, will use the facility to send tourists to space at a cost of $200,000 a ride.galactic suite ltd, set up in 2007, hopes to start its project with a single pod (分离舱) in orbit 280 miles above the earth. “it will take a day and a half to reach the pod, and the passengers will join it for three days,” claramunt said. more than 200 people have expressed an interest in traveling to the space hotel and at least 43 people have already reserved it.the numbers are similar for virgin galactic with 300 people already paid or signed up for the trip, but unlike branson, galactic suite says they will use russian rockets to transport their guests into space from a spaceport to be built on an island in the caribbean. but critics have questioned the project, saying the

in an interview with global forum big think. there have been a number of times in the past when its survival has been a question of touch and go. ”“i believe that the long-term future of the human
