世界上绝大多数动植物都能在我国找到适宜生长的地方,主要原因是(    )

A.季风气候显著

B.雨热同期

C.夏季普遍高温

D.气候复杂多样

答案

答案:D

题目分析:大多数动植物在我国能够找到适合的生长环境,说明我国的自然条件多样,主要原因是我国的气候复杂多样,季风气候提供了湿润的生长环境,大陆性气候也能给动植物提供特定的生长环境,所以选择D;而A、B、C选项着重从季风季候的特征回答显然是不全面的。

点评:动植物生长与气候因素关系密切。气候种类的差异决定了气温和降水的差异,是动植物生存的必要条件。本题的关键是我国农作物和动植物的种类多,所以应该选择我国的气候类型复杂多样。

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.

Which of the following did Marc NOT do to the patients()

A.Giving them operations.

B.Amusing them.

C.Administering medicine to them.

D.Sitting by their deathbeds.
