Passage One

My First Experience with AIDS Patients
我初次接触艾滋病人

by Marc Kielburger
I was ushered to the AIDS ward of a hospice in the slum.I would later learn that the ward did not exist,at least not officially.Not a single person in Thailand had AIDS,according to the Thai government at the time.People got"sick,"of course,sometimes"very sick."but no one had AIDS.The hospice was home to an ever-growing number of"very sick"people.
I entered the ward and was greeted by two Thai nurses.
"Thank goodness you are here,Marc,"said the first.
"You’re a doctor,right "
I shook my head.
"So you are a medical student then!"
I shook my head again.
"But you know medicine,right "
"Kinda,"I offered."I watch E.R.,every Thursday"
After a rapid exchange in Thai,the first one said,"NO problem.Get ready for your fou- hour medical school training!"
"But in my country medical school takes years!" I protested.
"We don’t have that long," she replied. "So we better get started. "
During the next few hours, I learned to clean wounds, administer IVs, treat bedsores, and dispense medicine. The work was punishing, made worse by stifling heat, frequent blackouts, and an incredible stench in the air. I tried desperately to hide my weak nerves and queasy stomach, but more than once dashed for the bathroom to throw up.
Just when it seemed my training was coming to an end, the nurse took me aside. "There are only two more things you need to know," she said. "On the left-hand side of the ward, you will find what we call the Exit Area. " As it turned out, she meant "exit" in the largest sense of the word. Terminally ill patients were hidden behind a curtain and then exited out of the ward after death. "The second thing you need to know," she continued, "is that we haven’t had a day off in three weeks. You’ll be looking after the ward by yourself for the next shift. "
My jaw dropped.
"Don’t worry, Mare," said the other nurse, patting me on the shoulder before turning to leave. "Think of this as the beginning of your residency !" And with that, they walked out. Alone and petrified, I tried unsuccessfully to keep calm.
I counted to twenty-four. That’s how many AIDS patients were in my charge. What am I going to do I thought. What can I do I fell back on my training with the Canadian government and put my talents to work. I served patients water-some with ice, some without. Next, I tried to cheer up everyone, myself included, giving enthusiastic high-fives to patient after patient. Soon enough, everyone was laughing. Some were laughing with me, others most definitely at me, but I didn’t care. As long as I could keep people smiling, I was sure it would all be fine. And it was. Until a short while later, when a patient in the Exit Area began to choke. He had fluid in his lungs and could not breathe. As I crossed the floor, I could hear the man gasping for air. Fumbling and scared, I pulled back the curtain and administered the medicine the nurses had recommended. The man didn’t respond. With nothing left to offer, I sat down and held his hand, looking into his eyes as he breathed heavily for a while and then stopped. Watching him slip away, I was hit by a feeling of anguish such as I’d never felt, either before or since. It haunts me to this day.

Judging from the passage, what is the writer most likely to be

A.A doctor

B.A medical student

C.A volunteer

D.A government official

Buying insurance (保险) is a way in which people can protect themselves against large losses. Protection against fire is one kind of insurance. Large numbers of people pay small sums of money to an insurance company. Although thousands of people have paid for fire insurance, only a few will lose their homes by fire. The insurance company will pay for these homes out of the small sums of money it has collected.

The first modern fire insurance company was formed in London, England, in the 1760s. A great fire had just destroyed most of the city, and people wanted protection against further losses. The first company grew rapidly. Soon other companies were founded in other areas.

Benjamin Franklin helped form the first fire insurance company in America in 1752, and then a new kind of insurance for farmers was suggested. The new insurance would provide protection against the loss of crops from storms.

Later on another new insurance company was started in America. This company, which offered life insurance, collected small sums of money regularly from many different men. If a man died, his family was given a large sum of money.

Over the years, insurance companies have offered new kinds of insurance protection. The new kinds of insurance cover losses from such accidents as car and plane crashes. Today, most people have some kind of insurance.
