【题目】 Over a four-year period, Swiss researchers have developed a machine that can keep human livers ()alive outside of the body for one week.

Livers are among the most commonly transplanted (移植)human organs. Current technology can only keep human livers alive for up to 24 hours. It is reported that, in 2017, about 8.000 liver transplants were performed in the U.S., of which 360 used livers from living givers In addition, about 11,500 people were registered on a waiting list to receive a liver transplant. Keeping livers alive and functioning for longer periods could greatly improve the chances of survival for patients.

The researchers say the purpose of their “Liver4Life” machine is to perform what they call liver perfusion (灌注)operations outside of the human body. Perfusion is the process by which blood or other liquids are pumped through organs and tissue. The machine keeps the liver at the right temperature and moves it in a way that would be natural in the body. Using a pump to fill the liver with blood acting like a human heart, the machine also provides oxygen to the organ, controls red blood cell levels and removes waste.

The research team began their experiments with livers from pigs. After repeated testing and engineering development, they succeeded in getting the pig livers to survive for seven days with support only provided from the Liver4Life machine. They also discovered the system can work to repair damaged livers. The team is now planning its next step to transplant machine-treated organs into patients.

Pierre-Alain Clavien. leader of the research said in a statement. “This technology will greatly increase the number of livers available for transplant, improving the chances of survival for patients. The success of this unique machine opens the way for many new applications in transplantation and cancer medicine.”

【题目】 A few weeks ago, I picked up my 14-year-old daughter and her friend from dance class. The two girls chatted happily until I reached her friend’s house. And then 1 began the drive home and my daughter, who had been talking nonstop a minute before, went completely silent. I assumed she was lost in thought.

When I came to a stoplight, I looked in the mirror. My daughter wasn’t looking out of the window or staring into space - she was on her phone. I felt my anger rise.

“Get off your phone. That is rude. You make me feel like an Uber driver.” I shouted.

“But I’m texting friends about biology homework!’’ she said.

“That can wait.” I was mad and she was angry.

Back home, she disappeared into her room, and I thought about how I was still trying to take control of my daughter’s growing independence, which was fruitless.

The next day I was thinking about my outburst when a parenting program on TV caught my eye, in which the hosts interviewed Dr. Ken Ginsburg, the author of a famous parenting book. It completely changed my attitude.

Ginsburg said. “Why are our teens pushing us away? It’s not because they hate us - it’s because they love us so much and yet they know they have to become independent. So this is a process of figuring out how to push away the things they love the most. It is crazy to fly from a comfortable nest, so teens get ready for it by temporarily pushing their parents away.”

I need to honor her independence and create space for both of us to face this monumental developmental challenge as teammates, not adversaries((对手).

1What made the writer mad?

A.She served as an Uber driver.

B.The two girls were chatting happily.

C.Her daughter was playing with the phone.

D.Her daughter forgot her biology homework.

2What do we know about the daughter?

A.She is being under her mother’s control.

B.She is on the way to being independent.

C.She enjoys making friends using social media.

D.She hates making conversation with her mom.

3Which of the following best describes the mother?

A.Open-minded.B.Hardworking.

C.Inspiring.D.weak-willed.

4What is the passage mainly about?

A.I was pushed away by my teenaged daughter.

B.Life of a teenager is moving at its own slow pace.

C.Parents completely rely on parenting experts to educate children.

D.My relationship with my daughter was improved by a suggestion.
