When I was struggling with cancer a few years ago，my wife and I formed our own “couple caution circle”．Anytime a doctor came with news of my progress，my wife would give me a big hug.

As we walked together down the hall，the doctor attempted to catch up with us.“Keep going，” said my wife，pushing the intravenous (静脉注射的) stand.“We’re going to talk to someone who really knows what is going on.” Then she held up her hand to the doctor.“Don’t come any closer to us.”
The two of us moved as one.We escaped to the safety and hope of a doctor who did not confuse diagnosis with conclusion. I could never have made that walk toward wellness alone.

Father was diagnosed with brain cancer during the second half of my senior year. It is a time when all the big events in a girl’s life are happening. However, though in poor condition, father managed to be present at every occasion. His doctor said that by focusing on all my future events, it helped my dad live longer. I guess so because nine days after my high school graduation, my father died.
For the next week after his funeral, I didn’t leave my room or even to shower. Finally, my mom stormed in and said, “Megan, get up. I have something for you to read.” My father’s doctor had sent my mother a letter. It contained the typical “I am sorry for your loss” sentences. But this letter was far from typical. I could physically see the pain this loss had caused him. In his letter, he wrote about how my father inspired him to change his life and the way he worked. He expressed his desire to become a person like my father, who cared more for the people around him and put everyone else first.
After I finished reading it, I decided to live my life. I went outside and got a job as a summer camp advisor. I worked from dawn to dark every day that summer. I gave everything I had to the kids and slowly they helped to heal(治愈) me without even realizing what they were doing.
My summer mirrored parts of the life my father led in his last few days. I had spent the summer months giving myself to children. It was not the senior summer I had always imagined. It wasn’t all about me. I had learned the final lesson my father was teaching me, that in order to lead a rich and happy life, you must learn how to give yourself to others. By helping them you really are helping yourself.

A.encourage the author’s mother to live a happy life

When my friend Lesa was diagnosed(诊断) with cancer, another friend and I went to the hospital to spend some time with her. We bought her a small toy and named him Lemon－Aide. We gave Lemon－Aide to Lesa and told her he was to go with her to all of her treatments to remind her that we were thinking of her and caring about her even though we could not always be with her. When the treatments were completed, she said when someone else needed him she would pass him along.
A few months later，much to my surprise, it was me that she passed him to. Lemon－Aide went with me to all of my treatments.
One day while waiting for my doctor I decided we could market the idea to fight cancer. Lesa thought it was a great idea so we founded the organization that came to be known as Lemon－Aide' s Friends, Inc. We designed our organization to remind people fighting cancer that there are people who love and care about them all the time. Today we have totally 5013 volunteers. The money raised is donated to cancer patients who do not have insurance. The physicians on our Board of Advisors determine how and where our money is donated.
Lemon－Aide is for men, women, and children of all ages and to date has been sent to 34 states and 33 countries to provide smiling support for people fighting cancer. When life gave us lemons we made Lemon－Aide, a soft smiling toy that represents love, support, and encouragement.

Three years ago when I was still in the university, I also worked at a restaurant.
An old man named Mr. Candido Filio was one of our regular customers at the restaurant. He was one of the most intelligent people I’ve ever known.
Every Sunday the Philippine Star Newspaper had a special page for word puzzles and among his peers (同龄人), Mr. Filio held the record for solving all the puzzles in less than five minutes. He encouraged me to solve them too and for months and months, I did my best to beat him but failed.
Then one Sunday, I did it! I was able to complete them before anyone else. Everyone cheered for me. He came up to me with a smile and said, “No one has ever beaten me before. You’re the first. I’ll have a prize for you tomorrow.”
The next day, he gave me a special Scrabble (拼字游戏) set. I would have never been able to afford one like that by myself. Then he said to me, “Kate, what do you think is man’s final goal in life? Happiness, isn’t it? You are happy and that should be considered as a success. Many people spend a lifetime searching for that. Be thankful that you have found it.” I looked at him and knew that my life had changed, probably forever. He must have known that I always felt sad about not having much money.
He encouraged me to learn the game and love words. And true to his words, I was never able to beat him again.

高二英语阅读理解困难题查看答案及解析
About five years ago, an American electrical engineer named Scott Brusaw and his wife Julie came up with the idea of putting solar panels on the ground rather than the roof. Then they began to develop the Solar Roadway specially for a new type of cars-eco-cars. The Solar Roadway is an intelligent road that provides clean renewable energy using power from the sun while providing safer driving conditions, along with power and data delivery. They predict that the Solar Roadway will pay for itself through the generation of electricity along with other forms of income and that the same amount of money that is being used to build and resurface current roads can be used to build the Solar Roadsays.
Each Solar Road Panel measures roughly 4 meters and contains a microprocessor（微处理器）that monitors and controls the panel, while communicating with neighboring panels and the vehicles traveling overhead. The inventors suggest that this provides a communication device every 4 meters on every road which could be used for example to warn drivers of cars which are moving across a centre line and various other speed control problems. The top of the Solar Road panels is made of super-strong glass that would offer vehicles the tractions（抓地力）they need.
According to the inventors, the Solar Roadway creates and carries clean renewable electricity and therefore electric vehicles can be recharged at any conveniently located rest stop, or at any business that has paved Solar Road Panels in their parking lots.
The inventors say their Solar Roadway has many functions and advantages from main roads to drivewasys, parking lots, bike paths, sidewalks and runways. The Federal Highway Administration has given Brusaw $100,000 to develop the invention and Brusaw hopes to build a smart-road parking lot in the coming spring.
1.In the inventors’ opinion, the Solar Roadway______.
A. is too expensive to build at present
B. costs no more money than current roads
C. can provide as many data as present computers
D. will bring them a large sum of money
2.The underlined word“they”in Paragraph 2 refers to______.
A. the panels B. the inventors C. the researchers D. the vehicles
3.The Solar Roadway includes all the following advantages EXCEPT_______.
A. providing safer driving conditions
B. helping drivers communicate with each other while driving
C. creating and carrying clean renewable electricity
D. warning drivers of various speed control problems
4.What can be the best title for the text?
A. Solar-powered smart road of the future
B. The great changes on the roadway
C. The influence the Solar Roadway has on people
D. The Solar Road-a much faster road

My name is Amy. I’m a 25-year-old graduate student who likes yoga, home-decorating shows and eating spoonfuls of peanut butter straight from the jar. Oh yeah, and I’m an iPhone addict.
I wasn’t always an addict. In fact, for many years I told myself I didn’t want a fancy cellphone. They seemed like too much work, always ringing and demanding attention. I was perfectly content with my simple cellphone, and I didn’t feel like changing my mind any time.
However, about a year ago, I found myself envious of all those proud iPhone owners, holding their shiny new phones and showing them off to all their friends. I started to eavesdrop on conversations about “iPhone apps”, feeling like a tourist listening to a language I couldn’t speak.
Eventually I couldn’t ignore my iPhone instinct (本能) any longer, and I welcomed my new iPhone into my life. I instantly fell in love with the little bundle of joy, and could no longer imagine a life without it.
To my surprise, I suddenly found myself with a whole new circle of friends—other iPhone owners I could go to for advice and support as I learned the various functions of my new device. They responded to my iPhone-related queries when my other friends couldn’t, and didn’t roll their eyes when I bragged（吹牛）about all the things little Eloise (yes, I named her) could do.
For a couple months I built my new life with Eloise. However, I realized I had a problem when one day I found myself Google-mapping my way to my mailbox, which happens to be right outside my front door.
When I reflected upon the past few months, I couldn’t believe I didn’t see this coming. All the warning signs were there. Eloise slept right beside me and was the first thing I reached for in the morning. I checked my e-mail about 20 times a day. I also experienced attachment anxiety when I left poor Eloise in the changing room at the gym. What if she rang and needed my response? Or, even worse, what if a careless gym-goer knocked her out of my bag and caused her screen to crack?
Once I admitted I had a problem, things started to change. What used to feel like friendly messages now felt like constant complaining to respond. I hated that I could no longer leave the house without Eloise in my hand. Eventually, I felt angry with Eloise so much that I wanted to throw her at the wall.
I decided something had to be done. But, as I quickly realized, iPhones are like cigarettes and not easy to quit.
Then, while taking the bus to work one day, I was unexpectedly forced to quit—at least temporarily. When I reached into my purse to grab Eloise, I found her overcome by fever. My head swam with panic as I attempted to solve the problem, but without result. I couldn’t call anyone for advice. I couldn’t Google whether this had happened to any fellow iPhone owners. The Apple Store was closed by the time I finished work, so I headed home with fear into an Eloise-less night. But, after a couple hours without any text alerts, push notifications, or even good old-fashioned phone calls, I felt ... calmer. Without my electronic bed partner, I drifted off into the deepest sleep I’d had in months. The next morning, I read the news from the simplicity of the newspaper, instead of from my iPhone. I even noticed the cherry blossoms blooming.
My goodness, what had I been missing?
1. The passage is mainly about ___________.
A. how I changed my attitude towards iPhone
B. why I was content with my iPhone
C. how my simple cellphone changed my lifestyle
D. why I preferred to use iPhone eventually
2. The phrase “ eavesdrop on” ( Paragraph 3) is closer in meaning to __________.
A. adapt suddenly to B. join unwillingly in
C. listen secretly to D. argue fiercely in
3.IPhones’__________ can not be listed among the reasons why the writer was addicted to it.
A. diverse application B. excellent service
C. bundle of joy D. good company
4.When did the writer get to know that she had to tear herself away from her iPhone?
A. She needed her iPhone to lead her to the mailbox.
B. She slept with her iPhone beside her every night.
C. She checked and read her e-mails too frequently.
D. She dared not leave her iPhone alone at the gym.
5.What message does the writer pass on at the end of the passage?
A. She considered throwing away her iPhone regretful.
B. She looked forward to starting her new life with Eloise.
C. She thought it of little benefit to have a simple cellphone.
D. She was aware that she had to kick the habit of being addicted to her iPhone.
