In recent decades, there is a phenomenon which makes us give some attention, the so-called Southeast Asian "Tigers" have rivaled the western"lions" for stock cliches that make economic headlines. The myth of American economic hegemony over Asia in the imposing and patriarchal figure of Uncle Sam has provided frequent political grist( 有利 ) for Southeast Asian political leaders,particularlyMalaysia'sPrimeMinisterMahathir.Hehasattemptedtoforgean international reputation as a snarling tiger, but lately sounds more like a barnyard dog groaning at shadows. Without demeaning in any way the remarkable achievements of the newly developing economics of Malaysia, Thailand and Indonesia, these nations at times appear to be their own worst enemies. This is often exemplified by Dr. Mahathir, who rails at Western evil whenever an international or domestic crisis provides an opportunity. To be more specific, the recent devaluation of the Philippine and Thai currencies, and the subsequent pressure on the Malaysian currency has inspired Dr. Mahathir to launch an all-out attack on the West as the source of the problem. He even alleges that the United States has deliberately destabilized Southeast Asian economics in revenge for these nations, supporting the brutal military rule in Mahathir, an action which the United States seems to want inspected rather than rewarded. But by resorting to such scapegoat(替罪羊), instead of accepting even a bit responsibility, the Prime Minister may undermine the future success of the region and Malaysia in particular. Upon further questioning, Dr. Mahathir narrowed his attack to one wealthy individual, the well-known philanthropist (慈善家), Mr. George Soros, whose opposition to Myanmar's admission to ASEAN(Association of Southeast Asian Nations) Mahathir found particularity, irritating. The logical mistakes that underlie such conspiracy theories do not help Malaysia address the serious issues of economic overheating that experts have been warning about for all these difficult periods,which include large deficits and low savings to debt ratios. In fact, the recent dramatic drop in Malaysia's stock market and currency has led Dr. Mahathir to reverse his initial approach to the crisis. He even announces measures that at least imply he is quite aware of excesses in his own administration's spending policies that have contributed to this crisis of confidence. In the end, this kind of reaction undermines the esteem that Dr. Mahathir's enlightened leadership has justly earned.Tickets to special exhibits at the botanical gardens may be reserved __________ advance.A.of B.in C.at D.for
共用题干第一篇Plant GasScientists have been studying natural sources of methane（甲烷，沼气）for decades but hadn't regarded plants as a producer, notes Frank Keppler, a geochemist（地球化学家）at the Max Planck Institute for Nuclear Physics in Heldelberg,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 amounts of the gas. They had assumed that microbes（微生物）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（室，房间；腔）that contained the same concentration of oxygen that Earth's atmosphere has.They measured the amounts of methane that were released by both living plants and dried plant material,such as fallen leaves.With the dried plants,the researchers took measurement at temperatures ranging from 30 degrees Celsius to 70 degrees C.At 30 degrees C.,they found,a gram of dried plant material released up to 3 nanograms（微克）of methane per hour(One nanogram is a millionth of a gram). With every 10-degree rise in temperature,the amount of methane released each hour roughly doubled.Living plants growing at their normal temperatures released as much as 370 nanograms of methane per gram of plant tissue per hour. Methane emissions tripled when living and dead plant was exposed to sunlight.Because there was plenty of oxygen available,it's unlikely that the types of bacteria(bacterium的复数，细菌）that normally make methane were involved. Experiments on plants that were grown in water rather than soil also resulted in methane emissions.That's another strong sign that the gas came from the plants and not soil microbes.The new finding is an"interesting observation,"says Jennifer Y. King,a biogeochemist（生物地球化学家）at the University of Minnesota in St. Paul. Because some types of soil microbes consume methane,they may prevent plant-produced methane from reaching the atmosphere.Field tests will be needed to assess the plant's influence,she notes.What is the beneficial point of some microbes consuming plant-produced methane?A:Methane becomes less poisonous.B:Methane is turned into a fertilizer.C:Less methane reaches the atmosphere.D:Air becomes cleaner.
