環境問題為託福常考話題以及獨立寫作常常可以轉化到的一個論證方向，那麼就讓我們來積累一些時尚新鮮的語言素材吧。從歐巴馬總統呼籲應對氣候變化威脅的電視講話中，我們無疑能夠得到許多可用的素材喲，一起來積累學習吧!
Hi, Monday, I'm heading to Alaska for a three-day tour of the state.
I've been looking forward to this for a long only because Alaska is one of the most beautiful places in a country that's full of beautiful places-but because I'll have several opportunities to meet with everyday Alaskans about what's going on in their lives.I'll travel throughout the state, meeting with Alaskans who live above the Arctic Circle, with Alaska natives, and with folks who earn their livelihoods through fishing and I expect to learn a thing I've learned so far is that a lot of these conversations begin with climate that's because Alaskans are already living with its frequent and extensive er storm surges as sea ice melts of the swiftest shoreline erosion in the world-in some places, more than three feet a year. Alaska's glaciers are melting faster too, threatening tourism and adding to rising if we do nothing, Alaskan temperatures are projected to rise between six and twelve degrees by the end of the century, changing all sorts of industries forever.

This is all is happening to our fellow Americans right fact, Alaska's governor recently told me that four villages are in “imminent danger” and have to be ady, rising sea levels are beginning to swallow one island k about another country threatened to wipe out an American town, we'd do everything in our power to protect ate change poses the same threat, right now. That's why one of the things I'll do while I'm in Alaska is to convene other nations to meet this ral Arctic nations have already committed to e the United States and China worked together to set ambitious climate targets last year, leading by example, many of the world's biggest emitters have come forward with new climate plans of their that's a good sign as we approach this December's global climate negotiations in Paris.

Now, one of the ways America is leading is by transitioning away from dirty energy sources that threaten our health and our environment, and by going all-in on clean, renewable energy sources like wind and Alaska has the natural resources to be a global leader in this effort.
Now even as we accelerate this transition, our economy still has to rely on oil and long as that's the case, I believe we should rely more on domestic production than on foreign imports, and we should demand the highest safety standards in the industry-our l, I know there are Americans who are concerned about oil companies drilling in environmentally sensitive are also concerned with my administration's decision to approve Shell's application to drill a well off the Alaskan coast, using leases they purchased before I took office.I share people's concerns about offshore drilling.I remember the BP spill in the Gulf of Mexico all too well.
語言素材:
從威脅健康和環境的'汙染能源向全面的清潔，可再生能源如風能太陽能轉變： transition away from dirty energy

更依靠國內生產而不是進口: rely more on domestic production than foreign imports
堅持最高安全標準: demand the highest safety standards
關注：be concerned about…
批准殼牌公司在阿拉斯加近海鑽井: approve Shell’s application to drill a well off the Alaskan coast
BP公司在墨西哥海岸的石油洩漏事故：the BP spill in the Gulf of Mexico
That's precisely why my administration has worked to make sure that our oil exploration conducted under these leases is done at the highest standards possible, with requirements specifically tailored to the risks of drilling off don't rubber-stamp made it clear that Shell has to meet our high standards in how they conduct their operations-and it's a testament to how rigorous we've applied those standards that Shell has delayed and limited its exploration off Alaska while trying to meet bottom line is, safety has been and will continue to be my administration's top priority when it comes to oil and gas exploration off America's precious coasts-even as we push our economy and the world to ultimately transition off of fossil fuels.
語言素材:
石油勘探工作：conduct the oil exploration
量身制定的要求去避免阿拉斯加近海鑽井的風險： the requirements specifically tailored to the risks of drilling off Alaska
不經審查就批准: rubber-stamp permits
滿足最高標準: meet our highest standards
測試多麼嚴格的執行那些標準: it is testament to how rigorous we’ve applied those standards.
So I'm looking forward to talking with Alaskans about how we can work together to make America the global leader on climate change around the we're going to offer unique and engaging ways for you to join me on this trip all week at
what's happening in Alaska is happening to 's our wakeup as long as I'm President, America will lead the world to meet the threat of climate change before it's too ks, and have a great weekend.
