1. A,根据第三段 The researchers created a device, called a reactor, which changes carbon dioxide into a pure form of formic acid, a substance (物资) found in ants and some other insects, as well as in many plants.可知答案为A。 2. C,根据最后一段他对未来的展望,可知他还是很有自信的,...
Carbon dioxide is one of the major greenhouse gases.Most of this heat-trapping gas is produced through human activities related to burning fossil fuels.Several major industries have attempted to move away from fossil fuels in favor of cleaner energy solutions. ...
1. According to the passage the root cause for weather changes on the Earth is ___. A. the atmosphere surrounding the EarthB. water from oceans and lakes C. energy from the Sun D. greenhouse gases in the sky 2. Only a small part of the Sun's energy reaches the Earth's surface...
“Smoke from wildfires contains a noxious mix of chemicals that affects not only air quality and health, but also damages plants, ecosystems and crops – and leads to more carbon emissions and so more greenhouse gases in the atmosphere,” says Dr Lorenzo Labrador, a WMO scientific offi...
major greenhouse gases concentrationδC_g value, CH and NO in loess-paleosol sequences are generally high, even sometimes may be several times or scores of times higher than their atmospheric concentrations respectively. Although the CO concentration in the same loess section shows poor regularity ...

根据第一段第一句Scientists blame greenhouse gases for being a major cause of climate change around the world.“科学家指责温室气体是全球气候变化的主要原因。”由此可知,“温室气体”是气候变化的主要原因。故选A。 (2)题详解: 细节理解题。根据第二段中Formic acid is a substance (物质) found in ants...
NO emission and preliminary estimation of annual NO emission from trees in mixed broad-leaved and Korean pine forest of Changbai Mountain The sources of N 2O,one of the major greenhouse gases in the atmosphere,are still unclear till now. It was previously considered that only soil microbial p...
Global warming and consequently the global climate change, resulting from the increasing concentrations of Greenhouse Gases (GHGs) in the atmosphere, caused by the use of fossil fuels and other anthropogenic activities is now an established phenomenon. Its effects have been observed in most parts of...
Scientists blame greenhouse gases for being a major cause of climate change around the world. This is because greenhouse gases trap heat in the atmosphere and make the planet warmer. Now, a team of researchers has announced a successful experiment that turned carbon dioxide into useful liquid fuel...
