“We finally have the first look at our Milky Way black hole, Sagittarius A*,”an international team of astrophysicists(天文物理学家)and researchers from the Event Horizon Telescope team announced     1    (proud)on Thursday.

For years, the supermassive black hole in the dark center of the Milky Way galaxy     2    (study)——and eventually, it’s been captured(捕捉)in an image. The black hole is often referred to     3     Sgr A*. Its mass is about 4 million times     4     of the sun, and it’s about 27,000 light years from Earth.

What made capturing the image extra     5    (challenge)was the dynamic enyironment of Sgr A*, and the challenges of looking not only through the earth’s atmosphere     6     also through the gas clouds in the disk of the Milky Way galaxy towards the center. It took several years to refine the images.

“Although we cannot see the black hole     7    (it), because it is completely dark, glowing(发光的)gas around it reveals a telltale signature, a dark central region    8    (surround)by a bright ring-like structure,” the Event Horizon Telescope team said in its announcement.

The     9    (discover)comes three years after the Event Horizon Telescope Collaboration released the first-ever image of a black hole—but that work focused on     10     center of galaxy Messier 87, tens of millions of light-years away from Earth in the Virgo cluster of galaxies.

Have you ever wondered     1     we say maidongxi (买东西) instead of mainanbei, and shangcesuo (上厕所) rather than xiacesuo? Many Chinese words have directions in them, and there is lots of history and culture     2     (hide) behind.

The origin of maidongxi     3     (date) back to the Tang Dynasty, when two markets gained     4     (popular) in capital Chang’an. One was called the East Market while the other was called the West Market. When shopping, people usually went to the East Market first,    5    then the West Market. This practice gave rise to the term of maidongxi.

Another case is yijian xiangzuo (意见相左).    6    great many Chinese are right-handed, and they may feel     7     (convenient) if they use their left hand to write or use chopsticks. Therefore, in ancient Chinese, “left” was easily linked to being different, such as yijian xiangzuo. Likewise, if people don’t accept common     8     (belief), we may say they are following pangmen zuodao.

Then came the story of shangcesuo and xiachufang. In ancient times, houses were laid out in a certain way,     9    gate would face south with a bathroom in the northeastern top and the kitchen in the southeastern bottom. In Chinese, we talk about “the north” as shang and “the south” as xia. So people would say they were going “up” to the bathroom and “down” to the kitchen. Shang and xia also reflect social status. For example, the emperor     10     (call) huangshang and dianxia usually means the prince.
