不必經過冷卻?
Scientists in South Korea published two papers on July 22 saying that they found the world’s first superconductor — a material called LK-99 — that operates at ambient temperatures.
南韓的科學家於7月22日發表了兩篇論文，聲稱他們找到了世界上第一種在常溫下運作的超導體，即一種名為LK-99的材料。
publish(v.)出版publish a paper發比論文paper(n.)紙(不可屬);論文(可數)operate(v.)運作(=function)ambient(adj.)周圍環境的;氣氛
This means it could be useful without being cooled.
這表示它不必經過冷卻也能使用。
useful(adj.)有用的(=of use)be of great use很好用
Despite the importance of this discovery, many international experts have doubted that the breakthrough is real and that the South Korean scientists’ experiments can be copied.
儘管這著實是一個重大發現，許多國際專家都懷疑這項突破的真實性及南韓科學家團隊本次實驗的可重複性。
despite(prep.)儘管(=in spite of)expert(n.)專家(+in／at／on sth.)expertise(n.)專業知識in doubt懷疑If in doubt, take it out.如果不確定，應拿掉。authenticity(n.)真實性exactitude(n.)準確性experiment(n.)實驗do／conduct／perform an experiment進行實驗
Superconductors are any materials that can float on magnetic fields and allow electricity to flow through them without resistance.
超導體是任何可以借助磁場浮在空中，且讓電流毫無阻力地通過它的材料。
material(n.)材料float(v.)漂浮(在空中或水上);浮現float one’s boat為～所喜歡float on air喜洋洋allow sb. to RV讓～做～flow through流通、流過flow(v.)流動;有的是、大量供應resistance(n.)阻抗、抵抗、電阻(+to sth.對～的抵抗)
If the findings about LK-99 are true, it would be great news for developing new superconductors that could help make electricity grids, computing and transportation more efficient.
如果LK-99的發現是真的，那麼就能開發新的超導體，並藉以提高電力網、運算和交通運輸的效率，實為一大好消息。
findings(n.)發現、研究結果(常為複數)It’s good news.這是好消息。efficient(adj.)有效率的effective(adj.)有效果的electricity grid電力網
Since the material would not need to be cooled with special equipment, it would be much easier to use.
由於這種材料不需要特殊設備來冷卻，使用起來會容易得多。
Currently, superconductors are only used in special settings, like MRI machines, where temperatures can be cooled down to and kept at extreme lows.
目前，超導體只能用在特殊環境，比如說在MRI機器裡，因為其溫度可降到並維持在極低溫狀態。
because(conj.)因為(在句中可替換為…in that…)settings(n.)場合、條件(=conditions)low(n.)低水平、低點;低谷
Unfortunately, the published papers’ findings have yet to be proven by other scientists.
可惜的是，已發表論文的發現尚未被其他科學家證實。
prove(v.)證實(prove-proved-proven)have yet to尚未
Although many have tried, they have not been able to come up with the same results.
儘管許多人已經嘗試，但他們還未能得出相同的結果。
although(conj.)雖然(=much as)come up with想出;拿出(一筆錢)
So far, the general belief among other scientists is that LK-99 seems to float because of special magnetic properties, but it is not a superconductor like the research papers say.
到目前為止，其他科學家普遍認為LK-99似乎因其特殊的磁性特性而浮動，但它並非如論文所說為超導體。
