貝拉克·奧巴馬即將成為年度暢銷書作家。他的妻子米歇爾·奧巴馬曾贏得過這個稱號，她所著的《成為：米歇爾·奧巴馬自傳》在2018年飆升至圖書銷售榜榜首。

Now the former president's new memoir, "A Promised Land," is breaking records for the book's publisher, Crown, an imprint of Penguin Random House.
如今，這位前總統(tǒng)的新回憶錄《應(yīng)許之地》正在打破該書出版商、企鵝蘭登書屋旗下的皇冠出版社的紀(jì)錄。

從應(yīng)對全球金融危機(jī)到通過《平價醫(yī)療法案》，《應(yīng)許之地》記錄了奧巴馬執(zhí)政期間最重要的一些時刻。

Hundreds of thousands of people pre-ordered "A Promised Land" ahead of Tuesday's release date.
在11月17日正式發(fā)售之前，已有數(shù)十萬人預(yù)訂了這本書。

Those pre-order sales, plus first-day sales, totaled 887,000 units "in all formats and editions in the US and Canada," Penguin Random House said on Wednesday.

>Marriages benefit from lockdown
疫情期間夫妻關(guān)系改善

One in five of marriages in the UK have benefited from the national lockdown, research has revealed.
研究表明，英國五分之一的夫妻在疫情封鎖期間關(guān)系有所改善。

A study carried out by the Marriage Foundation found 20% of married couples felt their relationship had strengthened, while only 9% said theirs had worsened during the pandemic.
英國婚姻基金會開展的這項研究發(fā)現(xiàn)，20%的已婚夫婦認(rèn)為他們的關(guān)系得以改善，只有9%的人表示夫妻關(guān)系在疫情期間惡化了。

Harry Benson, the Marriage Foundation's research director and one of the report's authors, said: "Our study debunks claims that lockdown is leading to a divorce boom.
婚姻基金會研究主任、報告的作者之一哈利·本森說："我們的研究讓'封鎖導(dǎo)致離婚潮'的說法不攻自破。

The data strongly suggests the opposite – spending more time with your husband or wife has been beneficial for large numbers of the UK's 12.8 million married couples."
數(shù)據(jù)有力地表明，事實正好相反，對于英國1280萬對夫妻中的大部分人來說，花更多時間和另一半相處益處良多。"

>Pink diamond sold for $26.6M
'玫瑰之魂'鉆石拍出1.76億

A giant, flawless pink diamond sold for $26.6 million at auction in Switzerland, according to Sotheby's auction house.
據(jù)蘇富比拍賣行稱，一顆巨大的、無瑕的粉色鉆石在瑞士拍賣會上以2660萬美元(約合人民幣1.76億元)的價格拍出。

On its website, the "Spirit of the Rose" diamond is described as a "superb and magnificent fancy vivid purple-pink diamond."
在蘇富比官網(wǎng)上，拍賣行將這顆"玫瑰之魂"鉆石描述為"頂級的、華麗的艷彩紫粉鉆"。

"Fancy vivid" is the gemological term for the deepest shade of pink diamonds.
"艷彩"是最深色粉鉆的寶石界術(shù)語。

The stone was unearthed in northeastern Russia in July 2017 and originally weighed 27.85 carats.
這顆鉆石于2017年7月開采于俄羅斯東北部，原石重27.85克拉。

It took over one year for gemologists to cut and polish the Spirit of the Rose down to its current 14.83 carat size; the gem is the largest pink diamond ever mined in Russia.
寶石專家用了一年多的時間對"玫瑰之魂"進(jìn)行切割打磨，該粉鉆成型后重14.83克拉，為俄羅斯有史以來開采出的最大粉鉆。

>Why plane windows are rounded
飛機(jī)舷窗為何是圓形的

While not everyone will have pondered the subject while staring out of the window during a flight, the question as to why airplanes have circular windows rather than square ones is interesting.
雖然不是每個人都會在飛行中凝視窗外的時候思索一個問題：為什么舷窗是圓形的而不是方形的。但這個問題很有趣。

Over the years, aerospace engineering has made huge leaps in airplane technology, meaning planes can carry more passengers and go faster.
多年來，航空航天工程在飛機(jī)技術(shù)上取得了巨大的飛躍，這意味著飛機(jī)可以運載更多的乘客，飛行速度更快。

The planes have also changed shape to increase safety – including the windows.
同時，為了提高安全性，飛機(jī)在外形上也做出了相應(yīng)的改變。舷窗，便是變化之一。

Where there's a corner, there's a weak spot.
哪里有拐角，哪里就有弱點。

Windows, having four corners, have four potential weak spots, making them likely to crash under stress – such as air pressure.
方形舷窗有四個角，就有著四個潛在的薄弱點，使它們很可能在壓力作用下破裂，比如大氣壓力。

By curving the window, the stress that would eventually crack the window corner is distributed, and the likelihood of it breaking is reduced.
因此，讓窗緣線條彎曲，來分散窗口四角的壓力，從而降低了窗戶破碎的可能性。
