阳光课堂同步练习系列答案Is it time to kick Russia out of the BRICs （金砖四国）? If so, it may end up sounding like a famous ball-point pen maker-BIC. An argument is being made that Goldman Sach’s famous marketing device（策略）,the BRICs, should really be the BICs.
“Is Russia really worth the name BRICs?” asks Anders Aslund, senior fellow at the Peterson Institute for International Economics, in an article for Foreigh Policy. Aslund, who is also co-author with Andrew Kuchins of “The Russian Balance Sheet”, thinks the Russia of Putin and Medvedev is just not worthy of inclusion alongside Brazil, India and China in the list of future economic powerhouses. He writes:
“The country’s economic performance has fallen to such a weak level that one must ask whether it has any say at all on the global economy, compared with the other members of its group. I have just returned from Moscow, which is always dull around this season. For the last seven years, Russia has taken very few measures to improve its economy. Instead, the state has been living on oil and gas. ”
Economically, Aslund has the numbers on his side. The International Monetary Fund figures that the Russian economy will fall by 6.7 percent in 2009, while China will grow 8.5 percent and India 5.4 percent. There is less of a case for Brazil, with a fall of 0.7 percent, but it is still doing
far better than Russia.
But the BRICs are not just about economy. As is mentioned above, it is a marketing device to encourage investors to focus on the big promising players. From an investment standpoint, it could be argued that Russia is leading the BRICs. Its stock（股票）market is up 128 percent this year while around 80 percent is for the other three.
At very least, however, Russia’s economic underperformance and stock market outperfoumance does suggest it is indeed one of the group.

| D．show disappointment to Russia’s economy |
In a surprising discovery about where higher life can survive, scientists have found a shrimp -like creature and a jellyfish swimming beneath an Antarctic ice sheet.
About 180 meters below the ice where no light can get through, scientists had figured nothing much more than a few microbes (微生物) could exist.
That’s why a NASA team was surprised when they lowered a video camera to get the first long look at the underbelly of an ice sheet in Antarctica. A curious shrimp-like creature came swimming by and then parked itself on the camera’s cable. Scientists also pulled up a tentacle (触须) they believe came from a jellyfish.
“We were operating on the presumption that nothing’s there.” said NASA ice scientist Robert Bindschadler. “It was a shrimp you’d enjoy havin
g on your plate.”
“We were just gaga (狂热的) over it,” he said when talking about the 7.5cm long, orange creature starring in their two-minute video. Technically, it’s not a shrimp. It’s a Lyssianasid amphipod, which is distantly related to the shrimp.
The video is likely to inspire experts to rethink what they know about life in harsh environments. And it has scientists thinking that if shrimp-like creatures can live below 180 meters of Antarctic ice in freezing dark water, what about other cold places? What about Europa, a frozen moon of Jupiter?
Cynan Ellis – Evans, a scientist of the British Antarctic Survey called the finding fascinating. He said it was possible the creatures swam in from far away and don’t live there permanently.
But Kim, who is a co-author of the study, doubts it. “The site in West Antarctica is at least 19 km from open seas. Bindschadler drilled a 20 cm-wide hole and was looking at a tiny amount of water. That means it’s unlikely that two creatures swam from great distances and were captured randomly in that small area,” she said.
“Yet scientists were puzzled at what the food source would be for these creatures. While some microbes can make their own food out of chemicals in the ocean, complex life like the shrimp can’t,” Kim said.
“So how do they survive? That’s the key question.” Kim said.
“It’s pretty amazing when you find a huge puzzle like that on a planet where we thought we know everything.” Kim said.
