高二英语单项填空简单题查看答案及解析

I was working the overnight shift in a remote hospital in the Rocky Mountains. Late in the evening, a young African teenager was brought into the emergency department. He lived at sea level and had never been in the mountains. After skiing all day, he felt really ill. Everyone assumed it was altitude sickness.

He was sweating and had abdominal (腹部的) pain. His heart rate increased. We sent off his lab work, and his blood sugar came back at almost 600 — normal is less than 100. His platelets (血小板), necessary for stopping bleeding, came in at 10,000; they should have been over 150,000. I did an ultrasound of his abdomen, and it looked like his belly was full of blood. This wasn't altitude sickness. And in the short time I'd been trying to figure out what was wrong, he was getting sicker. The friends he was traveling with were terrified, and rightly so.

The mystery was finally solved with an old-fashioned microscope. When we looked at his blood, we saw some sickled (镰形的) red blood cells. That's how we were able to diagnose sickle cell trait. If you have sickle cell trait — which means you got the sickle cell gene from just one parent instead of two — you have no symptoms at low altitude, but high altitude can sometimes cause the red blood cells to turn into sickle shapes and take oxygen from vital organs. This teenager didn't know he had it, but the effect of the altitude on his blood cells was so extreme that after just a short time in the mountains, he suffered great pain.

He needed platelets immediately, but we didn't have enough at the remote hospital. And there was a snowstorm, so the medical helicopters couldn't fly. It was a scary night. Just as we were abandoning all hope, we met an ambulance that drove halfway up from the city with blood products and transferred him to the city hospital for emergency surgery. The story has a happy ending: He recovered fully.

1.What do we know about the African teenager?

A. He only skied for a short while.

B. He lived in the Rocky Mountains.

C. He had never heard of altitude sickness.

D. He was unaware of the danger of high altitude.

2.What was the teenager's condition when rushed to the hospital?

A. He was feeling cold.　　 B. He was bleeding continually.

C. His heart rate was going down.　　 D. His blood contained little sugar.

3.How did the doctor diagnose the teenager's sickle cell trait?

A. By doing an ultrasound.　　 B. By examining his parents.

C. By using a traditional approach.　　 D. By doing a chemical experiment.

4.Which of the following played a part in saving the teenager according to the last paragraph?

A. Luck.　　 B. Money.

C. Fame.　　 D. Belief.

Seeds on Ice

Close to the North Pole，remote and rocky Plateau Mountain in the Norwegian archipelago of

Svalbard seems an unlikely spot for any global effort to safeguard agriculture. In this cold and deserted environment，no grains，no gardens，no trees can grow. Yet at the end of a 130-meter-long tunnel cut out of solid stone is a room filled with humanity’s most precious treasure, the largest and most diverse seed collection—more than a half-billion seeds.

A quiet rescue mission is under way. With growing evidence that unchecked climate change-will seriously affect food production and threaten the diversity （多样性） of crops around the world，the Svalbard Global Seed Vault （地窖） represents a major step towards ensuring the preservation （贮藏） of hundreds of thousands of crop varieties. This is a seed collection, but more importantly, it is a collection of the traits found within the seeds：the genes that give one variety resistance to a particular pest and another variety tolerance for hot，dry weather.

Few people will ever see or come into contact with the contents of this vault. In sealed boxes，behind multiple locked doors，monitored by electronic security systems, enveloped in below—zero temperatures, and surrounded by tons of rock, hundreds of millions of seeds are protected in their mountain fortress. Frozen in such conditions inside the mountain, seeds of most major crops will remain viable for hundreds of years, or longer. Seeds of some are capable of retaining （保留） their ability to grow for thousands of years.

Everyone can look back now and say that the Seed Vault was a good and obvious idea, and that of course the Norwegian government should have approved and funded it. But back in 2004, when the Seed Vault was proposed, it was viewed as a crazy，impractical, and expensive idea.

We knew that nothing would provide a definite guarantee. But we were tired，fed up，and frankly scared of the steady, greater losses of crop diversity. The Seed Vault was built by optimists who wanted to do something to preserve options so that humanity and its crops might be better prepared for change. If it simply resupplied seed gene banks with samples those gene banks had lost, this would repay our efforts.

The Seed Vault is about hope and commitrnent - about what can be done if countries come together and work cooperatively to accomplish something significant，long-lasting，and worthy of who we are and wish to be.

1.According to the passage, the Seed Vault is ___________.

A. a tunnel where the collected seeds are displayed

B. a stone room that contains the seeds of endangered crops

D. a lab where researchers study how to maintain the diversity of crops

2.The underlined word“viable”in Paragraph 3 probably means ________.

A. mature　　 B. clean

C. alive　　 D. valuable

3.Paragraph 3 mainly tells us __________.

A. how the seeds are preserved　　 B. where people keep the seeds

C. why the seeds are protected　　 D. what people do to study the seeds

4.We can know from the passage that _________.

A. the Seed Vault offers a solution to climate change

B. most countries took part in rescuing the seed varieties

C. the Seed Vault guarantees to prevent the loss of crop diversity

D. many people originally considered building the Seed Vault unwise
