2 . The definition of community has evolved (升华)for me from childhood to the young adult I am now. My mom was born in America but both her parents were from the Bahamas. It was their culture to take care of the elderly and the sick. And my mom has taught me to be caring to those around us because we're all a part of the "community" , an extension of family.
When I was 9 years old, my family moved to Cape Coral, Florida. Both mom and dad worked full-time, so they registered me to attend an after-school program at the Youth Center. Youth counselors (辅导员) would help me with my homework and play games with me and this was where my interest took root. Community service started with me giving back at the Youth Center.
Then illness struck at home. My grandmother had to have heart surgery and needed hospital treatment. This experience brought me to volunteer at Cape Coral Hospital. I asked if I could learn from the nurse how to give my grandma her medicine and it started here.
I loved being at Cape Coral Hospital. I would bring paperwork to other doctors, bring food to the patients, and make sure the patients were attended. I would help direct visitors to see patients. I would always tell what would cheer the patients up because I had built a relationship with them and their loved ones. I grew to feel the hospital was a part of my community.
After volunteering at the Youth Center and at the Hospital, I've learned that people become sort of an extended family when you care about them. Now I am more considerate of those close to me, neighbors and even strangers who share my resources.

4 . Have you ever run into a careless cell phone user on the street? Perhaps they were busy talking, texting or checking updates on WeChat without looking at what was going on around them. As the number of this new “species” of human has kept rising, they have been given a new name — phubbers (低头族).
Recently, a cartoon made by students from China Central Academy of Fine Arts put this group of people under the spotlight. In the short film, phubbers with various social identities（身份）are buried in their phones. A doctor plays with his cell phone while letting his patient die, a pretty woman takes selfie (自拍照)in front of a car accident site, and a father loses his child without knowing about it while using his mobile phone. A chain of similar events eventually leads to the destruction of the world.
Although the ending sounds overstated (夸大), the damage phubbing can bring is real. Your health is the first to bear the effect and result of it. “Continuously stretching (伸展) your head to check your cell phone could damage your neck,” Guangming Daily quoted doctors as saying, “the neck is like a rope that breaks after long-term stretching.” Also, staring at cell phones for long periods of time will damage your eyesight gradually, according to the report.
But that’s not all. Being a phubber could also damage your social skills and drive you away from your friends and family. At reunions with family or friends, many people tend to（往往） stick to their cell phones while others are chatting happily with each other and this creates a strange atmosphere, Qilu Evening News reported.
It can also cost you your life. There have been lots of reports on phubbers who fell to their death, suffered accidents, and were robbed (抢劫) of their cell phones in broad daylight.
1. The author gives the example of a cartoon in Paragraph 2 ________________.| A．to advertise the cartoon made by students. |
| B．to inform people of the bad effects of phubbing. |
| C．to show the world will finally be destroyed by phubbers. |

6 . The end of the school year was in sight and spirits were high. I was back teaching after an absence of 15 years, dealing with the various kinds of "forbidden fruit" that come out of book bags. Now was the spring of the water pistol.
I decided to think up a method of dealing with forbidden fruit.
"Please bring that pistol to me," I said. "I'm going to put it in my Grandma's Box."
"What's that?" they asked.
"It's a large wooden chest full of toys for my grandchildren," I replied,
"You don't have grandchildren," someone said.
"I don't now." I replied. "But someday I will. When I do, my box will be full of wonderful things for them."
My imaginary Grandma's Box worked like magic that spring, and later. Sometimes. students would ask me to describe all the things I had in it. Then I would try to remember the different possessions I supposedly had taken away—since I seldom actually kept them. Usually the offender would appear at the end of the day, and I would return the belonging.
The-years went by, and my first grandchild Gordon was born. I shared my joy with that year's class. Then someone said, "Now you can use your Grandma's Box." From then on instead of coming to ask their possessions back, the students would say, "That's okay. Put it in your Grandma's Box for Gordon."
I loved talking about the imaginary box, not only with my students but also with my own children. They enjoyed hearing about all the forbidden fruit I had collected. Then one Christmas I received a surprise gift—a large, beautifully made wooden chest. My son Bruce had made my Grandma's Box a reality.

8 . When Emanuel received an email from Professor Richard English. Queen’s Pro-Vice-Chancellor at the School of History, Anthropology,Philosophy and Politics, encouraging him to apply for a PhD in Politics in Belfast, it was a pinch-me moment Emanual never thought would be possible. After all, just a few short years ago, he was living on the streets couch-surfing at friends’ houses and weeding gardens to make ends meet. Now, one of the world’s leading political academics was preparing to welcome him to Queen’s University over 4,000 miles away.
Emanuel never knew who his father was and his mom was mentally ill when she gave birth to him, so the hospital took him off her and he was unofficially adopted for the first few years of his life. What followed was a childhood with uncertainty as Emanuel was passed between the adoption system and family members.
Through his high school and community college years, he moved from house to house, living with friends at times and living on the streets at others.
Determined to change all that despite his rocky start in life, Emanuel involved himself in school-doing everything he could to earn extra tuition (学费) money in his spare time. But getting accepted into university was scarcely possible because a person like him couldn’t get a regular student loan.
Fortunately, the government backed him, having created a policy allowing disadvantaged persons to access funding for higher education. He graduated from the University of the West Indies with a 1st Class Honors degree and went on to do his Masters.
Emanuel knows that his story could have been very different.
“I discovered Professor Richard English online and sent him an email honestly, not thinking he would reply and to my surprise, he did. I applied for the highly competitive Commonwealth Shared Scholarship Scheme in order to fund my research at Queen’s. When I was told I was successful, my whole world changed.”

| A．His father was mentally ill. |

| C．He was once adopted by his relatives. |

| A．By receiving a regular student loan. |
| B．By earning the tuition all by himself. |
| C．By borrowing the money from friends. |
| D．By getting support from the government. |
| A．Well begun is half done. |
| B．It’s never too old to learn. |
| C．You are the master of your life. |

10 . More than a billion people around the world have smart phones, almost all of which come with some kind of navigation app such as Apple Maps or Amap. This raises the age-old question we meet with any technology: What abilities is our brain losing to these apps? But also, importantly: What abilities are we gaining?
Talking with people who are good at finding their way around or good at using paper maps, I often hear a lot of annoyance with digital maps. North/south direction gets messed up, and you can see only a small section at a time. I can really understand that it may be quite disturbing for the already skilled to be limited to a small phone screen.
But consider what digital navigation aids have meant for someone like me. Although being a frequent traveler, I'm so terrible at finding my way that I still use Apple Maps almost every day in the small town where I have lived for many years.
In many developed nations, street names and house numbers can be meaningful, and instructions such as go north for three blocks and──then west’’ make sense to those familiar with these rules. In Istanbul, however, where I grew up, none of those hold true. For one thing, the locals seldom use street names. Besides, the city is full of winding and ancient alleys(小巷) that cross with newer avenues at many angles. In such places, you’d better turn to the locals. In the countryside, however, there is often nobody outside to ask. In fact, along came Apple Maps, like a fairy grandmother whispering directions in my ear. Since then, I travel with a lot more confidence, and my world has opened up.
Which brings me back to my original question: While we often lose some skills after depending on new technology, this new equipment may also allow us to gain new abilities. Maybe when technology closes a door, we should also look for the doors it opens.
1. Why do people who are skilled at reading paper maps feel upset?| A．They are interested in reading paper maps, |
| B．They don’t know how to use navigation, apps. |
| C．They are limited to a single smart phone app. |
| D．They are confused by digital maps’ direction. |
| A．Asking local people the way. |
| B．Following the navigation app. |
| C．Getting familiar with the city rules. |
| D．Looking for street names and house numbers. |
| A．Cautious | B．Ambiguous |
| C．Favorable | D．Critical |
| A．Benefits of Navigation Apps |
| B．Disadvantages of Navigation Apps |
| C．My World Opens Up by New Technology |
| D．Have Navigation Apps Worsened Our Brain? |
