Life in the Clear

Transparent animals let light pass through their bodies the same way light passes through a window. These animals typically live between the surface of the ocean and a depth of about 3,300 feet---as far as most light can reach. Most of them are extremely delicate and can be damaged by a simple touch. Sonke Johnsen, a scientist in biology, says, “These animals live through their life alone. They never touch anything unless they’re eating it, or unless something is eating them.”

And they are as clear as glass. How does an animal become see-through? It s trickier than you might think.

The objects around you are visible because they interact with light. Light typically travels in a straight line. But some materials slow and scatter (散射) light, bouncing it away from its original path. Others absorb light, stopping it dead in its tracks. Both scattering and absorption make an object look different from other objects around it, so you can see it easily.

But a transparent object doesn’t absorb or scatter light, at least not very much. Light can pass through it without bending or stopping. That means a transparent object doesn’t look very different from the surrounding air or water. You don’t see it you see the things behind it.

To become transparent, an animal needs to keep its body from absorbing or scattering light. Living materials can stop light because they contain pigments (色素) that absorb specific colors of light. But a transparent animal doesn’t have pigments, so its tissues won’t absorb light. According to Johnsen, avoiding absorption is actually easy. The real challenge is preventing light from scattering.

Animals are built of many different materials---skin, fat, and more---and light moves through each at a different speed. Every time light moves into a material with a new speed, it bends and scatters. Transparent animals use different tricks to fight scattering. Some animals are simply very small or extremely flat. Without much tissue to scatter light, it is easier to be see-through. Others build a large, clear mass of non-living jelly-like (果冻状的) material and spread themselves over it.

Larger transparent animals have the biggest challenge, because they have to make all the different tissues in their bodies slow down light exactly as much as water does. They need to look uniform. But how they’re doing it is still unknown. One thing is clear: for these larger animals, staying transparent is an active process. When they die, they turn a non-transparent milky white.

1.According to Paragraph 1,transparent animals 　　　　 .

A. stay in groups B. can be easily damaged

C. appear only in deep ocean D. are beautiful creatures

2.The underlined word “dead” in Paragraph 3 means 　　　　 .

A. silently B. gradually

C. regularly D. completely

3.One way for an animal to become transparent is to 　　　　 .

A. change the direction of light travel B. gather materials to scatter light

C. avoid the absorption of light D. grow bigger to stop light

4.The last paragraph tells us that larger transparent animals 　　　　 .

A. move more slowly in deep water

B. stay see-through even after death

C. produce more tissues for their survival

D. take effective action to reduce light spreading

In the U.S. state of Washington, a road called Interstate 90 cuts through a wild, mountainous area to reach the city of Seattle. For the area's many kinds of animals, the busy highway greatly limits their movements. Crossing 1-90—as the road is called—is a risky but sometimes necessary act. But soon, animals will have a safer choice for crossing the road. They will be able to go above it.

To help the animals, the state is finishing work on its largest-ever wildlife bridge. The 11-meter-tall, 20-meter-wide structure begins in the forest. It forms two arches above the highway, one for each direction of traffic. Workers are adding fencing and plants to help guide the animals across the bridge. Two-meter-thick walls will help block noise from vehicles below.

The 1-90 Bridge is part of a growing number of wildlife crossings across the United States. Some are fences, some are overland bridges, and some are underpasses. They all aim to keep drivers and animals away from each other. Collisions between animals and drivers are rarely deadly to people. But they are often deadly to wildlife. In Canada's Banff National Park, studies have found that wildlife crossings reduce the area's animal-driver collisions by 80 percent.

Most of the wildlife bridges are in western states. But experts have noted many other areas that have a need for such paths. Jen Watkins, whose organization has helped campaign for animal crossings, says ftind for more crossings is "the number-one barrier."

Patty Garvey-Darda of the U.S. Forest Service has worked on the 1-90 crossing from the start of the project. She says the $6- million bridge will one day pay for itself because the highway will not have to be fully or partly closed each time a large animal is struck. She said, 4tIf you shut down Interstate 90, you shut down interstate commerce.”

1.What is the purpose of building the bridge over “Interstate 90”?

A. To reduce human deaths in crash with wildlife.

B. To prevent wildlife from being struck by vehicles.

C. To arouse public awareness of wildlife protection.

D. To provide a safer choice to cross the risky road.

2.According to Jen Watkins, what is the biggest challenge in crossing construction?

A. Finding ways to help guide animals across the bridge.

B. Collecting money to build more wildlife crossings.

C. Locating areas to construct appropriate crossings.

D. Encourage drivers to obey the regulations of traffic.

3.What do the underlined words in Paragraph 5 imply?

A. The bridge will prove to be well worth the high price.

B. Expense for building such bridges will be reduced.

C. The bridge will greatly promote trade and commerce.

D. Lives saved through the bridge are definitely beyond price.

Some of the best cycling routes in the world pass through its most beautiful scenery. Here are some of world’s best bike routes for cyclists who either are up for breaking a good sweat or simply seeing the world without leaving an ugly carbon footprint behind.

The Great Windy Road, Victoria, Australia

If you like a challenge, take on this 243-kilometer windy road along Australia’s south-eastern coast. If a day is all you’ve got, take the 60-kilometer route from Torquay to Bells Beach. There you’ll cycle through rural farmland, enjoy the sweeping ocean views from cliff tops, and snake past the wetlands around Lake Connewarre.

Udaipur City Tour, Rajasthan, India

Biking is arguably the best way to explore Udaipur, Venice of the East.

Cyclists often need to cycle past herdsmen and their goats and camels, sharing narrow, old pavements in this romantic place. But surrounded by ancient castles, temples and grand palaces, Udaipur brings about one of the best biking experiences, allowing cyclists to truly discover rural India.

The Karakoram Highway, China-Pakistan

The Karakoram Highway is the highest international road in the world, reaching an altitude of 4,700 meters at the Khunjerab Pass. Starting in Kashgar, China, cyclists can travel up to 1,200 kilometers on mostly unpaved roads, but the views are as breathtaking as the riding.

Route of the Hiawatha, Idaho-Montana, United States

When I was a child growing up in Ohio, the butterflies would sometimes pass through on their way to Mexico. And it was awesome to see football fields full of them — and I wanted to revisit that on a larger scale. I knew I had to go to see the migration in Mexico.

But I was on a budget. I didn’t want to rent a car in Mexico or take a bus to Valle de Bravo, the starting point for most butterfly adventures, so I called the guys at the Muddy Boot, travel experts in Mexico who can make almost anything happen at a reasonable rate.

And so, on January 2, I found myself in the Muddy Boot van (货车), being driven two hours from Mexico City to Valle de Bravo, a lovely town on a volcanic lake which is a central point for the butterfly journeys. I booked a two-night stay at the Hotel Rodavento, an all eco-friendly hotel with individual wooden houses spread throughout the forest and around a lake.

The first sanctuary (保护区) I visited was Piedra Herrada, a popular destination, as it is only 40 minutes away from Valle de Bravo. The climb up is tiring. It is advisable to hire a horse. But the horse cannot take you all the way, and there is some hiking in thin air, so you must be patient, drink a lot of water, and be in reasonably good shape.

The walk is more than worth it, though. As I struggled to catch my breath, I looked up and lost my breath again. At first glance, the trees had turned into different shapes, but on closer inspection, every inch of them was covered with butterflies.

A few flew through the air (Most of them were not warm enough). As the sun rose, they began to come alive. Soon the air was filled with flying butterflies, transforming the forest into something magical and straight out of a fairy tale.

1.Why did the author choose to take the Muddy Boot van?

A.She couldn’t afford to rent a car.

B.She preferred to travel alone.

C.She wanted to save some money.

D.She hoped to reach the destination earlier.

2.What can we learn about Piedra Herrada?

A.It is at a high altitude. B.It is far from Valle de Bravo.

C.It is full of wild animals. D.It is only accessible by riding a horse.

3.What made the author’s hiking worthwhile?

A.Becoming healthier. B.Breathing in fresh air.

C.Finding trees of different shapes. D.Seeing the butterfly migration.

4.What type of writing is the text?

A.A news report. B.A scientific paper. C.A travel diary. D.A commercial ad.
