Paying it forward is a concept that involves doing something good for someone in response to a good deed done on your behalf or a gift you received. When you pay it forward, however，you don't repay the person who did something nice for you. Instead, you do something nice for someone else.
Recently, an inspiring note found inside a random book has inspired thousands of people to pay it forward.
Ashley Jost was shopping at Target when a book caught hex eye. The 27-year-old bought the book Girl Stop Apologizing and began reading it when she got home. After a few minutes her dog started barking so she put the book aside. When she got back, she noticed something on the ground. "A five-dollar note fell out, " Jost said.

Remember that you are loved, you are amazing, and you are strong -Lisa”
Jost decided to post a photo of the note and the money on Twitter and it went like a virus. People are promising their own random acts of kindness.
“In that moment，I didn’t necessarily need the pick-me-up，but I feel obligated(有义务的)to share it， and I’m hearing back from people who did,” Jost said. “The ripple effect is pretty unbelievable.
After seeing her Twitter post, Lisa mailed Jost a card. "She said it made her cry in a good way,” Jost said. But Lisa still didn’t give away who she was. She left no return address. Lisa wrote it had been a difficult time in her life and she just wanted "to create something positive-she never really expected this to happen the way it has.”

What will you get if you ask middle schoolers to show you their city through a camera? There may be images of flowers and friends, street scenes and sneakers, and trees and trains. It can also include colorful images featuring their favorite people, places and things. Such photographs made up an exhibition that was the end result of a special citywide photography lesson called “Everyday DC”.
“DC is a place where people can all come together and be free and be with everyone that they love,” said Lauryn Tharpe, one of the four student curators (馆长) who worked with their art teacher at Brookland Middle School to put the exhibition together. “There’s more to DC than big buildings and important people.”
“Everyday DC” was inspired by a popular Instagram feed called Everyday Africa, which was started by two professional photographers who noticed the personal photos of Africa, from their perspective (视角) showing a different story than their professional work. The goal of the online photo “exhibition” was to show viewers what it’s like to live in Africa, as opposed to what people outside of Africa see in the news.
In Washington DC, students took photos to reflect their lives there. Twelve middle schools each submitted about 10 student photographs, from beautiful portraits to action shots and images of the students’ favorite foods. Tharpe and another three students were selected to be curators by their art teacher, Maame Bawuah, who coordinated (协调) the project for DC Public Schools.
“I have a lot of amazing students, although the four of them are quite exceptional,” said Bawuah, who chose the students to be curators because of their interest in both photography and museum management.
A curator is someone who collects, organizes, cares for and displays anything in a collection. To get ready for the exhibition, the curators had to take care of many tasks, including taking their photos according to different themes.
1.What do we know about the “Everyday DC” exhibition?
A.It promoted the students’ interest in museum management.
B.It reflected the diverse life from the students’ perspective.
C.It was established by Lauryn Tharpe and Maame Bawuah.
D.It exhibited photos featuring influential things and figure.
2.Why does the author mention Everyday Africa?
A.To introduce how Everyday DC came about.
B.To highlight Everyday Africa’s popularity.
C.To compare Everyday Africa with Everyday DC.
D.To show the widespread influence of Instagram.
3.What are the four curators required to do for the project?
A.Decorate the photographs on display.
B.Study professional photography skills.
C.Find fault with the submitted photos.
D.Group the photographs by theme.
4.What is the best title for the text?
A.A lesson on running museums B.A citywide exhibition
C.Photograph your life D.Admire your city

A mind-reading chip that lets you control a computer by just thinking has been made public at a conference in China. Named Brain Talker, the chip could be used to control computers, smart phones and other devices, its creators say. It has been jointly developed by Tianjin University and China Electronics Corporation.
This kind of brain-computer interface (接口) is designed to let a person control a computer, a smartphone or other electronic devices using his/her brainwaves alone-without needing any forms of verbal orders, movements, or button pressing. Brain interfaces would not only allow for the faster operation of various technologies, but also be used to assist people with disabilities, for example by letting an individual drive an electric wheelchair just by thinking.
“Brain-computer interfaces hold a promising future,” said Dong Ming. "The Brain Talker chip advances brain-computer interface technology, allowing it to become more portable, wearable and accessible to the general public.
The brain decoding (解码) chip works by picking out minor neural (神经) electrical signals in the brain and rapidly translating them into a form that the computer can understand. “This brain-computer chip has the ability to identify minor neural electrical signals and decode their information efficiently, which can greatly enhance the speed and accuracy of brain-computer interfaces，” said Dr. Dong.
Recent technology advances have allowed researchers to develop the Brain Talker chip, so it is smaller and operates faster, more precisely and with greater efficiency than existing brain-computer interfaces. Although it is not clear exactly how the device will be worn, most brain-computer interface devices are worn on the outside of the body, rather than being fixed directly into the users’ brain. Cheng Longlong, a data scientist, said that the research team will attempt to improve the performance of the Brain Talker. One day brain-computer codec chips will contribute to medical treatment, education, self-discipline, security as well as games and entertainment.
1.Why do the creators develop the Brain Talker?
A.To improve the quality of a smartphone
B.To create more efficient electronic devices
C.To make the computer portable and accessible
D.To assist people to faster drive electronic devices
2.What does Dr Dong expect of the Brain Talker?
A.It has an uncertain future B.It can record people's brainwaves
C.It can be widely used by the public D.It will advance public entertainment
3.What is the fourth paragraph mainly about?
A.How the chip controls computer.
B.How the brain works with a computer.
C.How the brain processes information
D.How the chip picks out neural electrical signals.
4.What can be inferred from the last paragraph?
A.The chip will be worn inside the users’ body
B.It's too challenging to improve the Brain Talk
C.The performance of the Brain Talker is satisfying
D.Some patients will benefit from the Brain Talker

阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。 续写的词数应为150左右。
I sat at the breakfast table with my four-year-old son, Matthew, trying to ignore the ache in my stomach. “Mama, want to play?” “Not today, baby,” I shook my head. These days I could barely get out of bed. I was still recovering from a surgery. I hoped for strength and happiness. But the future seemed so hopeless.
Suddenly, Matthew jumped up from his spot on the kitchen floor. “Bird!” he shouted, rushing to our courtyard. Sure enough, there was a white dove seated in a rubber tree. It sat there for a few moments, and then flew away. Strange, I'd never seen one in our neighborhood before.
When I dragged myself to the kitchen the next morning, the dove was back. This time with a mate carrying twigs. “Look, Matthew,” I said, pointing to the tree. “They ’re going to make a nest.” The doves flew in and out of the courtyard all week, building on top of the rubber tree.
Matthew could hardly contain his excitement. Every morning, he'd run into the kitchen and take his spot by the sliding glass door, talking to the birds while they worked. His enthusiasm was influential. As much as I was grieving, I couldn't help but look forward to the doves' visits too.
Then it all went wrong. The courtyard was a safe enough spot for a nest, but the rubber tree's broad, thin leaves were far from stable. One night, a strong wind blew, throwing the doves' nest to the ground. I heard the twigs break apart.
I surveyed the damage. Nothing good ever lasts. I wouldn't blame the doves if they never came back. But they returned. And they paid no attention to the pile of sticks that had once been their nest.They started again from scratch. Again, though, the wind destroyed all their hard work. The next day, and the next, they renewed their efforts, as if nothing had happened.
Paragraph I:
I knew I had to do something.____________________________________________________
Paragraph II:
“It works! The birds are back!” Matthew announced.__________________________________
