2 . Cao Yuan, a PhD student from China, had two papers published on strange behaviour in atom-thick layers of carbon that have opened up a new field of physics.
Pablo Jarillo-Herrero’s group at MIT was already layering and rotating (旋转) sheets of carbon at different angles when Cao joined the lab in 2014. Cao’s job was to find out what happened when one graphene (石墨烯) sheet was twisted only slightly wiht respect to the other, which one theory predicted would thoroughly change the material’s behaviour.
Many physicists doubted the idea. But when Cao set out to create the subtly twisted stacks, he spotted something strange. Exposed to a small electric field and cooled to 1.7 degrees above absolute zero, the graphene—which ordinarily conducts electricity—became an insulator. That by itself was surprising. But the best was yet to come: with a slight change to the field, the twisted sheets became a superconductor, in which electricity flowed without resistance.
The ability to get atom-thick carbon into a complex electronic state through a simple rotation now has physics demanding to engineer exciting behavior in other twisted 2D materials. Some even hope that graphene could shed light on how more-complex materials superconduct at much higher temperatures. "There are so many things we can do," says Cory Dean, a physicist at Columbia University. "The opportunities at hand now are almost irresistible."
Hitting graphene’s “magic angle”—a rotation between parallel sheets of around 1.1°—involved some trial and error, but Cao was soon able to do it reliably. His experimental skill was extremely important, says his supervisor Jarillo-Herrero. Cao pioneered a method of tearing a single sheet of graphene so that he could create a stack of two layers, from which he could then fine-tune alignment (微调校准).
Cao loves to take things apart and rebuild them. A heart, he is “a tinkerer”, his supervisor says. On his own time, this means photographing the night sky using homemade cameras and telescopes—pieces of which usually lie across Cao’s office. "Every ime I go in, it’s a huge mess, with computers taken apart and pieces of telescope all over his desk," says Jarillo-Herrero.

Mother Teresa was born in Macedonia on August 26, 1910. When she was young, she had studied religion and loved everyone. Later, she went to India but taught Geography there for many year.
In 1950, she found the Missionaries of Charity in Calcutta, that aims to help the poor. Its members are volunteers. Mother Teresa devoted all her life to take care of the poor, the sickness, the homeless and the dying. That devotion won him respect throughout the world and Nobel Peace in 1979. In her later life, Mother Teresa suffered great from heart disease. She died at 87 on September 5, 1997 in India.

9 . 随着神舟十一号成功发射,宇航员景海鹏也为世人瞩目,他是中国第一位3次升入太空的宇航员,以下是他接受记者采访的话语节选和简历。
“After the completion of Shenzhou9 mission, we will prepare for the next. We will be ready for the selection of our motherland, to make new contributions to China’s manned space program.”
“I think during our lifetime, we need to set for us one dream after another and one goal after another, and to try our best towards the set objective (目标).”
“The Olympic Games is held every four years. I conducted my first space mission (任务) in 2008, and then again second in 2012, and now, another four years has just passed. I think I need to learn from Chinese Olympic shooter Wang Yifu, who has participated in nine Olympic Games. I still have a long way to go.”
