Small wonder Africa grew poorer between 1980 and 2000.难怪在1980至2000年期间,非洲变得更穷了。Now inflation has largely been tamed, most central banks are islands of excellence and many ministers boast of cutting red tape.现在,通货膨胀已经得到了极大遏制,大多数央行表现卓越,很多部长级高官都以简化政府流程为夸耀的资本。Five of the ten fastest reformers in the World Bank’s latest report on the ease of doing business are African.世界最近一次的营商便利度报告中,十个改进速度最快的国家中有五个都在非洲。Better government has led to better results.更好的政府带来了更好的发展。The proportion of Africans living in absolute poverty has fallen from 58% to 41% since 2000.非洲的赤贫人口占比已从2000年的58%下降至41%,In that time primary-school enrolment has risen from 60% to 80%. Annual malaria deaths have fallen by more than 60%.同期的小学入学率从60%升至80%。每年因疟疾致死的人数已经下降了超过60%。Pessimists fret that much of this progress will reverse now that Africa faces economic headwinds.持悲观态度的投资者担心非洲经济遇到强劲逆风,大多所取得的进步都会倒退。There are some worrying signs.现在也的确有一些令人担忧的征兆。Leaders once hailed as democrats are amending constitutions to escape term limits.一些曾被尊为民主主义者的领导人们正在试图修改宪法以突破任期限制。In Congo, Joseph Kabila’s efforts to cling to power risk restarting a civil war, as the president of neighbouring Burundi aly has.在刚果,约瑟夫?卡比拉(Joseph Kabila)对权力撒手不放,有可能会再次引发内战,邻国布隆迪的总统就是前车之鉴。The continent’s two biggest economies are making needless and costly policy errors.非洲两个最大的经济体在政策方面正在犯下不必要且成本高昂的错误。Nigeria is trying to prop up its overvalued currency by, in effect, banning imports.尼日利亚实际上在试图通过禁止进口来撑其估值过高的货币,然而事与愿违,Instead it is driving up inflation.这反而推高了国内的通货膨胀。South Africa, meanwhile, has prompted capital flight and brought economic growth to a halt by keeping in power a president who was found to have breached the constitution and on whose watch corruption has flourished.同时,南非因保留了已被发现违宪且纵容腐败的总统,导致资本外逃,经济停滞。But massive missteps like these are now the exception rather than the rule.然而这种弥天大错仅仅是例外,并不具有普遍性。Most countries in Africa are following sound economic policies, controlling government deficits and keeping inflation in check.非洲大部分国家都在遵循明智的经济发展政策,控制政府赤字,遏制通货膨胀。Dig beneath the headlines, and even in countries that are making big errors there is momentum for reform:深挖到新闻头条背后就会发现,即使在犯下大错的国家,仍然有着改革的动力:in South Africa once-taboo policies such as privatisation are back on the table, and in Nigeria the government is clamping down on corruption and trimming a bloated civil service.在南非,如私有化等政策不再是禁忌,又重新得以讨论;在尼日利亚,政府正在打击腐败,精简庞大的公务员队伍;Ethiopia is sucking in foreign investment, and smaller economies such as Ivory Coast and Rwanda are growing rapidly after making it easier to do business.埃塞俄比亚正在吸收外资;而一些小经济体,如科特迪瓦和卢旺达,在改善营商环境之后增长迅速。 /201605/440738。

If youre like many people, when you think of algae you picture the unsightly green film that forms on neglected swimming pools and fish tanks.如许多人一样,当你想到藻类的时候,你会在脑海中即刻闪现出在无人问津的游泳池和鱼池里表面覆盖着一层难看的绿膜的画面。Scientists, however, have made some discoveries that might change the way you think about this common plant.然而科学家的发现却可以改变你对这种普通植物的看法。Researchers are working on ways to use algae to reduce our dependence on fossil fuels to powercars, trucks, and even airplanes.研究人员正致力于如何利用藻类来减少我们对用化石燃料发动小车,卡车甚至飞机的依赖。Algae has attracted attention because it is simple and economicalto grow and carries fewer financial and environmental costs when compared to other alternatives.藻类会引起科学家们的注意是因为相对于其它可选择的燃料来说,种植藻类更简单,经济,并且花费的财政和环境成本较少。Algae needs only water to grow, and can use fresh water, salt water, marshlands, and evenwastewater for a habitat.只要有水藻类就可以存活,它可以在淡水,咸水,沼泽地,甚至污水中生长。The plants highly-adapted photosynthesis process allows it to thriveanywhere that abundant sunshine can be found.该植物高度适应的光合作用过程让其在任何阳光充足的地方都能茁壮成长。And even sunshine is optional for this versatile plant because scientists have discovered ways to grow algae in the dark using sugar as a food source.甚是阳光也只是一个可选择的条件,因为科学家们发现通过把糖作为食物来源也可以在黑暗中种植藻类。To use algae as a replacement for fossil fuels, oil is extracted from the plant and developed into abiofuel that can be burned in diesel engines.若用藻类代替化石燃料,油就会从植物中提取出来,并被加工为可以在柴油机中燃烧的生物燃料。The yield produced from the algae has proven fargreater than other biofuels currently being developed.藻类的产量大大高于目前正在开发的其他生物燃料。For example, soy produces an averageyield of fifty gallons of biofuel per acre per year.例如,大豆平均每年每英亩可生产五十加仑的生物燃料。Canola, another common alternative, producesroughly 130 gallons of biofuel per acre per year.菜籽,另一种常见的替代品,平均每年每英亩大约可生产130加仑。In contrast, scientists have found that algae can produce up to 4,000 gallons of biofuel per acre per year.与此相反,科学家们发现藻类平均每年每英亩可生产达4000加仑。In addition, because algae can be grown on water rather than land and without fertilizers, it may prove to be a more efficient and environmentally sound alternative to the biofuels in use today.此外,藻类可以在水中而不是陆地上生长,也不需要施肥。因此可以明目前在使用的生物燃料中它是更有效更环保的替代品。In the future, then, when you see algae you might think about more than just pond scum!未来,当你看到藻类的时候你或许想到的不仅仅是“池塘败类”。201409/332188。

Point at a ball and a dog will look at the ball, whereas a cat will probably look at your hand.当你用手指着球,会注视着球,而猫则可能会盯着你的手看个不停。Dogs seem to have a y understanding of how human beings direct attention by pointing,and can follow our gestures almost as if they thought the same way we do.汪星人似乎已通过方向很好理解人类做出的指示,并且可以跟随我们的手势好像它们和我们一样。Of course, dogs probably arent born knowing anything about people.当然,出生时可能并不了解任何关于人类的事情。We just carefully train them to look, fetch,and so on, right? Or do we?我们只是小心谨慎的训练他们观察,获取等等对吗?还是我们?A comparative psychologist at the Max Plank Institute in Germany,Michael Tomasello,ran a series of tests on dogs which they find which sealed container had yummy dog food in it.德国马克斯普朗克研究所的比较心理学家迈克尔托马塞洛对这种动物进行了一系列的实验观察它们能否找到密闭容器中的美味粮。The only hint they got was from a human being who looked or pointed at the right container.唯一的暗示是一名正观察或指向正确容器的人类。This wasnt hard for dogs at all.这对而言根本不算难题。 201502/358330。
