[单项选择]Practice, practice, practice. Studying a word won’t help very much if you quickly forget it. The saying" practice makes perfect" is certainly true in vocabulary learning. Research shows that it takes from 10 to 20 repetitions of a word to really make it a part of your vocabulary. It helps to write down the word—both the definition and a sentence using it—perhaps on an index card, where it can be easily reviewed. Review your index cards regularly to see if you have forgotten any new words.
Repeating a new word less than 10 times, a learner is likely to
A. remember it.
B. forget its meaning.
C. know how to use it.
D. know its spellin

Plant Gas
Scientists have been studying natural sources of methane for decades but hadn’t regarded plants as a producer, notes Frank Keppler, a geochemist at the Max Planck Institute for Nuclear Physics in Heidelberg, Germany. Now Keppler and his colleagues find that plants, from grasses to trees, may also be sources of the greenhouse gas. This is really surprising, because most scientists assumed that methane production requires an oxygen-free environment.
Previously, researchers had thought that it was impossible for plants to make significant mounts of the gas. They had assumed that microbes need to be in environments without oxygen to produce methane. Methane is a greenhouse gas, like carbon dioxide. Gases such as methane and carbon dioxide trap heat in Earth’s atmosphere and contribute to global warming.
In its experiments, Keppler’s team used sealed chambers that contained the same concentration of oxygen that Earth’s a
A. It was produced from plants.
B. It was not a greenhouse gas.
C. It was produced in oxygen-free environments.
D. It traps more heat than any other greenhouse gas.

[单项选择]　　Scientists studying the effect of large volcanic eruptions on global climate have long focused on the major quantities of carbon dioxide (C02), a gas known to contribute to the greenhouse effect, produced by these eruptions. It is well observed that such greenhouse gases trap heat radiated from the surface of the earth, thereby forming a type of insulation around the planet. The greenhouse effect is essential for ecological equipoise because it maintains the temperature of the planet within habitable parameters, but there is growing concern that man-made production of gases such as CO[,2] from the burning of fossil fuels may be threatening the system’’s tolerance, and have resulted in excessive warming on a global scale. While volcanic eruptions indubitably metabolize and accumulate C0[,2] in the atmosphere, it has been recently discovered that their impact is virtually trivial compared to the quantity produced by human activities, especially heavy industry. In reality, the more subs
A. The deep and enduring effect that volcanic eruptions have on the environment
B. The process by which classic volcanic eruptions tend to occur
C. The relative dearth of cases with scientists can judge the effects of volcain eruptions
D. A sample case with which later volcanic explosions are compared
E. The global cooling effects of one of the best-studied volcanic eruptions
