1 . Set in the rosy sandstone desert of northeastern Arizona, Canyon de Chelly National Monument is filled with paradox (悖论), because although the ruins are vast, they give us more questions than answers. Home of a large population, the settlement at Canyon de Chelly seems to have been abandoned almost overnight, for no apparent reason.

Archaeologists (考古学家) have found that people lived in Canyon de Chelly for longer than they lived in almost any other place in early America. Filled with beauty, the national monument covers 131 square miles, including the canyons of the de Chelly, del Muerto, and Monument River. With steep canyon walls and rushing rivers, this is an excellent place to explore cool spots on the canyon floors.

Most park guests arrive by car and begin their visit at the overlooks on South Rim Drive or North Rim Drive. The changes of altitude in the monument are truly dramatic with thousands of feet drops. For example, the highest park overlook is at 7, 000 feet while the visitor’s center is at 5, 500 feet. On the South Rim Drive, you’ll find the White House Ruin is located in a long, low cave in a rocky face. While hiking the White House Ruin Trail, be on the lookout for wildflowers and rock art. For a fun side trip, head to the Bighorn Canyon National Recreation Area, home to 700 different plant species, including many gorgeous wildflowers.

In nearby Chinle, Arizona, you can arrange for special park guides. The weather can be unpredictable here, so always carry a raincoat with you, prepared for sudden afternoon showers. Generally, the spring and fall are the best limes to visit. Summer is hot and dry, and winter is cold, and snowy. In the fall, be particularly aware of thunderstorms that can blow in quickly.

2 . Most people can't wait for spring to arrive. It means flowers and warmer weather, all welcome changes from the dark winter days. Now we know that spring is arriving sooner in the Northern Hemisphere   (北半球）than it was in the past, thanks to a study published in Scientific Reports.

For example, Los Angeles may experience spring only a day earlier than it did 10 years ago, but further north, in Seattle or Chicago, spring will arrive four days earlier. If you lived in the Arctic, spring could arrive 16 days earlier than it used to.

To determine how springtime is starting earlier, researchers looked at temperature records and 743 earlier studies over 86 years. These studies were about various biological indicators of spring, including birds migrating, plants flowering and amphibians（两栖动物）sounding their mating calls. Researchers then studied these data to see if they were occurring earlier. The result showed that not only is spring making itself known sooner but it's warmer, too.

Before you go out in a happy springtime hike, spring arriving sooner isn't so good. The livelihood of migratory birds, for instance, may be concerned.

“The food that birds rely on when they move to the north might not be reliable if the beginning of spring at these higher latitudes（维度）is expanded by future warming." said Eric Post. He is a fellow of the John Muir Institute and a polar ecologist.

Animals relying on Arctic sea ice, like polar bears, probably aren't crazy about things warming up sooner, either, because it impacts on their ability to hunt. Spring's early arrival could cause disorder in the delicate balance of various ecosystems~~not to mention how soon you'll need to buy allergy medicine.

1. We learn from the study published in Scientific Reports that.

A．spring comes earliest in Los Angeles

B．Los Angeles is further north than Seattle

C．spring comes 12 days earlier in Arctic than in Chicago

D．the further north a place lies, the sooner spring comes than before

2. Researchers made the discovery mainly by.

A．comparing related data available

B．conducting research and test

C．calculating the exact length of each spring

D．observing animal's behavior all year round

3. What do the last two paragraphs focus on?

A．Concerns over spring's early arrival.

B．Springtime emergence of creatures.

C．Early springtime's impacts on humans.

D．Disorder in the balance of ecosystems.

4. In which section of a magazine can we read this text?

A．Medical Report.	B．Survival Stories.
C．Scientific Discoveries.	D．Natural environment
