Zhong Nanshan, the 84-year-old epidemiologist was again put into the public eye with the COVID-19 outbreak.

On Jan. 18, 2020, while millions of Chinese were heading back home for the 【1】 Lunar New year, Zhong took high-speed railway to Wuhan, capital city of Hubei Province and the epicenter of the COVID-19 outbreak. Zhong only took a short rest at the dining car of the train 【2】 of his “standing-room-only ticket”.

After careful study, Zhong announced on Jan. 20 that the COVID-19 can be transmitted（传播）【3】 person to person and 【4】 people not to travel to and from Wuhan.. Three days later, Wuhan was put in lockdown.

Zhong is still fighting on the frontline of the COVID-19 outbreak. He has become a 【5】 for Chinese people at this difficult time.

The possibilities of 3-D printing seem endless. All the user has to do is to design(设计) an object on the computer and choose a material(材料) to print in. The printers print in hundreds of different materials including glass, sugar and even skin! When the user presses “print”, the 3-D printer spreads the material layer(层) by layer and like magic the object is produced.

The first 3-D printer was invented in 1986 by an American, Charles Hull. But 3-D printing has only become cheap enough recently for most people to use. Designers now use 3-D printing to create unusual things. The Dutch artist Dirk Vander Kooj prints furniture made from old fridges. And doctors have used 3-D printing to print human body parts! The Telegraph reported in February that scientists from Cornell Medical College even printed a man-made ear.

But like a lot of new technologies, if 3-D printing gets into the wrong hands, it can be dangerous. In 2011 a group of four men in the US used 3-D printing to produce ATM skimmers (提款机盗刷器). These were placed on an ATM and stole over $400,000 from users of the ATM. It is terrible to think that criminals like them might one day use a 3-D printer to print a gun.

But for better or for worse, 3-D printing has been put into use. In a few years, you’ll probably be wondering how you could ever live without your 3-D printer!

“My heart was beating fast. I was shaking, and I was so nervous.” Alice, Emma’s stepdaughter, said. She gave her step-mother the surprise of a life time.

“①that, it, amazing, so, I, hardly, it, could, read, was（.）” Emma said. She read some of the letter aloud. “Without you, I wouldn’t be the woman I am today.”

“It was five pages about how amazing she is and each page had a picture of her, and then at the end said ‘Will you accept me?’” Alice said. ②The paper behind it was the one where she had to sign it.

Emma has known Alice since she was a little baby. “I never liked the word ‘step’ because some people aren’t only step-parents. Some people are worth being birth parents but in our situation it was just the way it was. They were my own,” she said. ③尽管这个生日礼物可能不是最好的，但是对她来说这是最珍贵的。 “I’m just thankful that she is in my life,” Emma said.

“It’s not just blood that makes you a family. Because she’s been there for me, I regard her as my birth mother.” Alice said. Alice is expecting to get a new birth certificate（证明书）in the next three months.
