Far from the land of Antarctica (南极洲), a huge shelf of ice meets the ocean. At the underside of the shelf there lives a small fish, the Antarctic cod.
For forty years scientists have been curious about that fish. How does it live where most fish would freeze to death? It must have some secret. The Antarctic is not a comfortable place to work and research has been slow. Now it seems we have an answer. Research was begun by cutting holes in the ice and catching the fish. Scientists studied the fish’s blood and measured its freezing point. The fish were taken from seawater that had a temperature of -1.88°C and many tiny pieces of ice floating in it. The blood of the fish did not begin to freeze until its temperature was lowered to -2.05°C. That small difference is enough for the fish to live at the freezing temperature of the ice-salt mixture.
The scientists’ next research job was clear: Find out what in the fish’s blood kept it from freezing. Their search led to some really strange thing made up of a protein (蛋白质) never before seen in the blood of a fish. When it was removed, the blood froze at seawater temperature. When it was put back, the blood again had its antifreeze quality and a lowered freezing point.
Study showed that it is an unusual kind of protein. It has many small sugar molecules held in special positions within each big protein molecule. Because of its sugar content, it is called a glycoprotein. So it has come to be called the antifreeze fish glycoprotein, or AFGP.

Crossing Texas and Mexico, the Big Bend region is high in biodiversity(生物的多样性). It’s a place so untamed that if something doesn’t bite, stick, or sting, it’s probably a rock.
You know you have arrived in the heart of the Chihuahuan Desert when it feels as if you have fallen off the edge of the earth and into the rabbit hole. Nothing is as it appears. Moths (蛀虫) are the size of birds. Are those twin pillars (柱) of black rock (a landmark known as Mule Ear Peaks) ten miles (16 kilometers) away or fifty (80 kilometers)? Visibility (能见度) reaches more than a hundred miles on a clear day, and since there are few roads or buildings to use as milestones, distance is difficult to judge.
This is a place where water runs uphill, where rainbows have to wait for rain. The line between myth (虚构的故事) and reality is unclear. Stare long enough at the Chisos Mountains or the Sierra del Carmen, the two mountain ranges, known as sky islands, which lie on the land, and they rise and float above the plain.
The vast Chihuahuan Desert is a land of no people. There is always the chance you’ll die of thirst. The “You Can Die”possibilities are endless, and keep some visitors — 350,000 a year to Big Bend National Park, built in 1944 — from coming back. Those who do return are left to think of the remarkable courage of the brave few who have managed to survive in this terrible environment.
【小题1】The underlined word“untamed”in Paragraph 1 means“________”.
| A．untouched | B．wild | C．unchanged | D．fresh |
| A．They were put so far away. |
| B．They lie across the Chihuahuan Desert. |
| C．It is difficult to judge the distance, with few milestones. |
| D．One lies in the Chisos Mountains, the other in the Sierra del Carmen. |
| A．350,000 years. | B．350 years. | C．66 years. | D．44 years. |
| A．The natural wonders of the Chihuahuan Desert. |
| B．Everything you see is not what it seems in the Chihuahuan Desert. |
| C．The terrible environment of deserts in Texas and Mexico. |
| D．A special place where none who go can return. |
| A．There are all kinds of living things in the Chihuahuan Desert. |
| B．No people live in the Big Bend region. |
| C．Nothing is as it appears in the Big Bend region. |
| D．Traveling in the Big Bend region is dangerous. |
