26.The word “plummeting” (Para.2) is closest in meaning to ____（單詞）

27. According to Paragraph 3, the use of renewable energy in America ____（細節(jié)）

28. It can be learned that in Iowa, ____（推細節(jié)）

29. Which of the following is true about clean energy according to Paragraphs 5 & 6?（推細節(jié)）

30. It can be inferred from the last paragraph that renewable energy ____（推細節(jié)）

題干多次出現(xiàn)……energy，所以energy是主旨詞，而30題是最后一段推主旨詞，所以先做30題可能得到主旨

30. It can be inferred from the last paragraph that renewable energy ____

A. will bring the US closer to other countries.

B. will accelerate global environmental change.

C. is not really encouraged by the US government.

D. is not competitive enough with regard to its cost.

C中not really，為否定詞+絕對化=全集，所以選項的暗示看選C

定位renewable energy在第一句，While there’s a long way to go, the trend lines for renewables are spiking內(nèi)容上沒有對應(yīng)的部分，其他地方都沒有出現(xiàn)renewable energy，所以反向定位，A的other countries沒有提到，所以排除，B的global environmental在第二句中slowing climate change，但選項上加速，所以B排除，C定位US government為最后一句的Washington，為does—or doesn’t do—to promote alternative energy為支持和不支持的態(tài)度，也就是C中的不完全鼓勵，D定位cost沒有對應(yīng)的部分，所以選C

26.The word “plummeting” (Para.2) is closest in meaning to ____

A. stabilizing.

B. changing.

C. falling.

D. rising.

從選項的暗示看，CD成立時B成立，所以答案選B

從原文看，But increasingly the story is about the plummeting prices of renewables, especially wind and solar.為the plummeting prices，而本句沒有價格與之對應(yīng)，所以看周圍句中的價格，下一句出現(xiàn)了The cost of solar panels has dropped by 80 percent and the cost of wind turbines by close to one-third in the past eight years.為has dropped和close to one-third是下降的意思，對應(yīng)C，所以答案選C（選項的暗示為預(yù)判，實際答案是原文定位>選項暗示）

27. According to Paragraph 3, the use of renewable energy in America ____

A. is progressing notably.

B. is as extensive as in Europe.

C. faces many challenges.

D. has proved to be impractical.

定位renewable energy in America在第三段第三句，While the rest of the world takes the lead, notably China and Europe, the United States is also seeing a remarkable shift.中While表前后之間是對立，但后半句出現(xiàn)了also，說明前后之間的關(guān)系是遞進，而前半句是notably China and Europe，所以后半句也應(yīng)該是notably，為the United States，可以對應(yīng)A的意思，所以選A

28. It can be learned that in Iowa, ____

A. wind is a widely used energy source.

B. wind energy has replaced fossil fuels.（has replaced已經(jīng)被取代，絕對化）

C. tech giants are investing in clean energy.

D. there is a shortage of clean energy supply.

定位Iowa在第四段第二句In a recent speech in Iowa, he dismissed wind power as an unreliable energy source和第三句But that message did not play well with many in Iowa, where wind turbines dot the fields and provide 36 percent of the state’s electricity generation—and where tech giants like Microsoft are being attracted by the availability of clean energy to power their data centers.A的廣泛能量來源（wind turbines dot the fields and provide 36 percent of the state’s electricity generation，部分對應(yīng)），B的完全取代沒有出現(xiàn)，C的投資沒有出現(xiàn)（tech giants like Microsoft are being attracted by the availability of clean energy to power their data centers意思是被吸引，但沒有投資），D的能源短缺也沒有出現(xiàn)，所以選A

29. Which of the following is true about clean energy according to Paragraphs 5 & 6?

A. Its application has boosted battery storage.

B. It is commonly used in car manufacturing.

C. Its continuous supply is becoming a reality.

D. Its sustainable exploitation will remain difficult.

定位clean energy，但五六段沒有出現(xiàn)，所以發(fā)生了同義替換，直接按照推段落做，第五段定位在第二句But a boost in the storage capacity of batteries is making their ability to keep power flowing around the clock more likely.出現(xiàn)了A的boosted battery storage，但選項是Its application，Its指代clean energy，原文出現(xiàn)了their，前指代為第一句中的wind，可以對應(yīng)clean energy，但原句的意思是making their ability to keep power flowing around the clock more likely更有可能使他們有能力流暢的供電，而選項A是他們應(yīng)用在battery storage，所以A排除，但本句的more likely可以對應(yīng)C的is becoming a reality，并且continuous supply可以對應(yīng)keep power flowing around，并且此處的邏輯主語是their，為clean energy，可以對應(yīng)C的意思，所以選C
