15、enerosity and advocacy for the fight against global poverty. We just disagree about how to end poverty throughout the world. Gates believes poverty will end by identifying technical solutions. My research shows that the first step is not identifying technical solutions, but ensuring poor people“s ri
16、ghts. Gates concentrates his foundation“s efforts on finding the right fixes to the problems of the world“s poor. Along with official aid donors, the foundation works together with local, generally autocratic(独裁的), governments on these technical solutions. Last year, Gates cited Ethiopia(埃塞俄比亚) in a
17、 Wall Street Journal guest column as an example, a country where he described the donors and government as setting “clear goals, choosing an approach, measuring results, and then using those measurements to continually refine our approach.“ Gates then gives credit for progress to the rulers. When th
18、e tragically high death rates of Ethiopian children fell from 2005 to 2010, Gates said this was “in large part thanks to“ such a measurement-driven program by Ethiopia“s autocrat Meles Zenawi, who had ruled since 1991. Do autocratic rulers like Meles really deserve the credit? Gates“ technocratic ap
19、proach to poverty, combining expert advice and cooperative local rulers, is a view that has appealed for decades to foundations and aid agencies. But if technical solutions to poverty are so straight forward, why had these rulers not already used them? The technical solutions have been missing for s
20、o long in Ethiopia and other poor countries because autocrats are more motivated to stay in power than to fix the problems of poverty. Autocracy itself perpetuates poverty. Our own history in the U.S. shows how we can protest bad government actions and reward good actions with our rights to protest
21、and to vote. We won“t even let New Jersey Gov. Chris Christie get away with a traffic jam on a bridge. Such democratic rights make technical fixes happen, and produce a far better long-run record on reducing poverty, disease and hunger than autocracies. If the democratic view of development is corre
22、ct, the lessons for Gates are clear: Don“t give undeserved credit and praise to autocrats. Don“t campaign for more official aid to autocrats. Redirect aid to democrats. If the democratic view is wrong, I do deserve to be on Gates“ list of the world“s most misguided economists.（分数：20.00）(1).Who possi

30、g has been banned in many public places such as shops, restaurants, and even bus stops. This regulation has triggered much dispute. On the one hand, many welcome the ban since lots of illnesses and deaths are smoking-related, and this is a very sensible step to improve people“s health and living con
31、dition. On the other hand, however, smokers consider it is unfair to ban smoking. It is their right to smoke, and they are not committing any crime, so the government should not ban that. In my view, to ban smoking is a long term process, during which education rather than enforcement is more likely
32、 to be the key to the success. Banning smoking in the public areas is a policy that should be implemented step by step. 解析 这篇作文要求考生结合社会现象论述自己的观点。可如下组织行文结构： 先提出越来越多的公共场所禁烟这个现象，也可顺带提出这个现象的社会背景(最容易想到的是由吸烟引发的健康问题，以及禁烟可给人们营造一种干净、舒适的环境等)。 再指出这一规定引发反响，从拥护和反对这两个角度来说。 最后简要提出自己的观点，可针对上段中说到的拥护和争议，在其间找到一个平衡点，提出
33、自己的观点以及解决办法等。 总的来说，拥护的理由好说，关键是提出什么样的争议。可从法规执行的难度，惩罚措施是否适当等方面进行论述。范文是从吸烟者的自由权利遭损害这个角度来说的。二、Part Reading Compr(总题数：0，分数：0.00)四、Passage One(总题数：1，分数：71.00)Arctic Ocean ice may hold trillions of small pieces of plastic and other synthetic trash, and they are being released into the world“s oceans as glo
