[案例一] 背景 某高速公路M合同段，路面采用沥青混凝土，路线长19.2km。该路段地处平原地区，路基横断面以填方3～6m高的路堤为主，借方量大，借方的含石量40%～60%。地表层以黏土为主，其中K7+200～K9+800段，地表层土厚7～8m，土的天然含水量为40%～52%，地表无常年积水，孔隙比为1.2～1.32，属典型的软土地基。结合实际情况，经过设计、监理、施工三方论证，决定采用砂井进行软基处理，其施工工艺包括加料压密、桩管沉入、机具定位、拔管、整平原地面等。完工后，经实践证明效果良好。 在施工过程中，针对土石填筑工程，项目部根据作业内容选择了推土机、铲运机、羊足碾、布耠．机、压路机、洒水车、平地机和自卸汽车以及滑模摊铺机等机械设备。在铺筑沥青混凝土路面面层时，因沥青混凝土摊铺机操作失误致使一工人受伤，并造成设备故障。事故发生后，项目部将受伤工人送医院治疗，并组织人员对设备进行了抢修，使当天铺筑工作顺利完成。 问题： 选择施工机械时，除了考虑作业内容外，还应考虑哪些因素针对土石填筑施工，项目部所选择的机械是否妥当请说明理由。
Two pressing problems face the world: economic meltdown and global warming. Conveniently, a solution presents itself that apparently solves both: governments should invest heavily in green technology, thus boosting demand while transforming the energy business. This notion is gaining agreement around the world. Last month the United Nations called for a "Global Green New Deal". But it is in America that the idea is really taking off. The United States Conference of Mayors reckons that green investment should provide 2.5m jobs. The Centre for American Progress thinks $100 billion worth of spending in the area would provide 2m jobs. The new president tops both. Barack Obama proposes spending $150 billion over ten years, thus helping, he says, to create 5m jobs. There is a historical parallel to this synergy between two worthy aims. Just as military spending at the end of the 1930s defeated both fascism and the Depression, so spending on fighting climate change should both wean (使摆脱) mankind off fossil fuels and avert what might otherwise turn into the most serious downturn (衰退) since the 1930s. Isn’t that neat But combining the two by subsidizing renewable energy is, like many easy answers, the wrong solution. Governments can discourage companies and people from producing CO2 by making polluters pay or by reducing the costs of clean energy. Europe does both, through a cap-and-trade system (which caps CO2 emissions and requires companies to buy permits to pollute) and through subsidies. Mr. Obama is, quite rightly, planning to introduce a cap-and-trade system, but he is also promising massive subsidies. Subsidies are more popular but both theory and practice argue against them. Subsidizing clean energy requires politicians to decide on the best way of delivering it, and their judgment is likely to be worse than the market’s. America’s huge ethanol (乙醇) subsidies, for instance, have led to overinvestment in the businesses, which is now experiencing a sharp crash, and have helped drive up the price of food, with painful consequences for the world’s poor. The easy notion that there is a single solution to the world’s economic and climatic problems is, thus, a dangerous one. The world needs America to lead the fight against climate change. But if Mr. Obama goes about it the easy way, rather than the right way, he will discredit the cause he advocates, and thus damage the planet instead of saving it. Which of the following is true of the subsides in America
