In the earthquake and tsunami, Japan faces its most serious crisis in a generation. The terrible human toll is still being（1）, even as relief efforts accelerate, the estimate of live lost have（2）from a few hundred in the hours after the flooding to projections surpassing 10, 000. And（3）the humanitarian scale of the disaster is coming into（4）, the ultimate scope of the crises at the Fukushima Daiichi, Fukushima Daini and Onagawa nuclear power plant remains（5）, as does the extent of damage to critical infrastructure（6）the country’s North Pacific coast.In the midst of the disaster, economists and policy makers are（7）with the delicate task of assessing the implications of current events for Japan’s already-tenuous economic（8）. The analysis is far-reaching in its relevance, not least because of Japan’s position（9）the world’s third-largest economy, the challenges it already faces in moving toward fiscal sustainability and its role in supporting global financial markets, （10）currency markets and the market for U.S. treasuries.In（11）of the earthquake, the economic（12）for Japan was already fairy dim. The economy was projected to grow（13）just 1.7 percent in 2011, according to consensus estimates, roughly half the（14）of the United States. Significant new fiscal（15）to support the economy was largely ruled out given the country’s already substantial budget deficit.

Scientists have discovered that addictions may be（1）. A team from Britain’s University of Cambridge found that（2）of drug addicts share the same brain abnormalities as their drug（3）brothers and sisters. The research team said these abnormal brain structures are linked to（4） self-control and drug dependence. The researchers suggest that addiction is in some ways a “（5）of the brain”. This may provide important new ways into helping people with problems of self-control when it（6） to addictions. The study sought to find out if drugs changed the “（7）” of the brain or whether the brains of drug addicts were wired differently from（8）.Lead researcher Dr Karen Ersche told the BBC: “It has（9）been known that not everyone who（10）drugs becomes addicted.” She continued: “It shows that drug addiction is not a（11）of lifestyle, it is a disorder of the brain and we need to recognize this. These brothers and sisters who don’t have addiction problems, what they can tell us is how they（12）these problems, how they manage self-control in their（13）life.” Dr Ersche and her colleagues studied 50（14）of siblings, one with a history of drug addiction and one with no（15）of taking drugs. She compared these with 50 healthy people. She concluded: “We need to find out how these non-addicted siblings were able to resist using drugs.” 暂未登录
