A glimpse at the “private, hidden face” of Albert Einstein, including the celebrated scientist's thoughts on everything from his fears 【小题1】 his best work was behind him to his beloved younger sister, Maja.

The collection, which includes a previously unknown photograph of Einstein as a five-year-old and the only 【小题2】 （survive）letter written by Einstein to his father, comes from the archive（档案）of Maja Winterler-Einstein and her husband Paul Winteler. A mix of letters, postcards and photographs, many of 【小题3】 have not previously been published, range in date from 1897 to 1951.

“What is remarkable about them comes from the fact that he had this incredibly close relationship with his sister. It's quite clear that 【小题4】 he's writing to her, there's no role-playing at all.” said Thomas Venning at Christie's. which will auction（拍卖）the letters soon. “He was very conscious of what 【小题5】 （expect）of him after he became famous, and you don't get any of that in letters to his sister. He says some things that I've never seen him say anywhere else. and I've catalogued many hundreds of his letters.”

In 1924, nine years after he completed the general theory of relativity in 1915. Einstein would write to Maja that “scientifically I haven't achieved much recently-the brain gradually goes oft （停止） 【小题6】 age, though that is not so unpleasant. It also means that you're not so answerable for your later years.” Ten years later, he would write to her: “I am happy in my work, 【小题7】 in this and in other matters I am starting to feel that the brilliance of younger years is past.”

Venning said he had not seen Einstein 【小题8】 （admit）this anywhere else. “It's not him 【小题9】 （play）a role: you can see that thought going through his head, which is true-if Einstein had died in 1916, his fiundamental legacy would have been complete. He carried on working for another 40 years without making any other great breakthrough, so it's just an extraordinary moment which we get because of 【小题10】 close their relationship was. He didn't have to reassure（使安心）her,” he said.

Katherine Johnson Dies at 101； Mathematician Broke Barriers at NASA

They asked Katherine Johnson for the moon, and she gave it to them.

【小题1】 (use) little more than a pencil, a slide rule and one of the finest mathematical minds in the country, Mrs. Johnson, who died at 101 on Monday, calculated the precise trajectories(轨道)that would let Apollo 11 land on the moon in 1969 and, after Neil Armstrong's history-making moonwalk, 【小题2】(let) it return to Earth.

Yet throughout Mrs. Johnson's 33 years in NASA and for 【小题3】 (decade) afterward, almost no one knew her name.

Mrs. Johnson was one of several hundred strictly educated, extremely capable yet largely 【小题4】 (mention) women who are well before the modern feminist movement. worked as NASA mathematicians. But 【小题5】was not only her sex that kept her long marginalized and long unsung.

For some years at midcentury, the black women worked as "computers” 【小题6】 were subjected to a double segregation(隔离歧视):They【小题7】 (keep) separate from the much 【小题8】(large) group of white women who in turn were segregated from the agency's male mathematicians and engineers.

In old age. Mrs. Johnson became 【小题9】 most celebrated of the small excellent group of black women who at midcentury served【小题10】 mathematicians for the space agency. Their story was told in the 2016 Hollywood film "Hidden Figures”, which was nominated for three Oscars, including Best Picture.

From classics to movies

He can recite Shakespeare’s Hamlet from memory. His favorite ancient myth is The Odyssey. Tom Hiddleston, 32, could have been a popular professor teaching English Literature at a university, but the well-educated British man chose 【小题1】(do) something that he loved even more: acting.

He’s well-known around the world as the villain Loki from the Hollywood films Thor (2011), The Avengers (2012) and now Thor: The Dark World, which will come out in China on Nov 8. Hiddleston’s role as Thor’s evil brother has led to his fans — “Hiddlestoners” —【小题2】 (refer) to him as “the most charming villain” in cinema.

【小题3】 his charm, Hiddleston had a tough time 【小题4】 (persuade) his scientist father that acting was a worthwhile job. As a student at Eton, a private school for upper-class kids in England, Hiddleston performed in a lot of school plays. At 18, he appeared on stage at the Edinburgh International Festival. “It was the first time that people I knew and loved and respected had come up to me after the show and said: ‘You could really do this 【小题5】 you wanted to’,” Hiddleston told the Daily Mail.

He said that as a teenager he didn’t have much self-esteem, but acting gave him confidence. “It was when they started saying I could do it 【小题6】 I really committed to it as a possibility,” he continued. However, his father did not approve, believing his polite and bright son should be using his brains for 【小题7】 else. “You’ve been educated, so why do you want to spend your life pretending to be someone else when you could be your own man?” the father told the son.

So, instead of going to drama school, Hiddleston went to Cambridge, 【小题8】 he studied classics. There, he continued to appear in student plays and even landed some roles on TV and in local theaters. He managed to balance his acting and his studies so well that he graduated with 【小题9】 first-class degree.

But Hiddleston’s international breakthrough came when he auditioned for the 2011 film Thor. He was desperate to play the title superhero, but the director decided that he was 【小题10】 (suitable) for the part of the villain, Loki.

In the end, his dark and powerful performance won over his father. It also earned him some important fans in the film industry: Steven Spielberg and Woody Allen. The two world-famous directors asked him to star in their award-winning films War Horse (2011) and Midnight in Paris (2011), respectively.
