</p>第三篇 The Book of Life
2 o4 a( Q# ]* }) X% u6 Y$ |So far, scientists have named about 1.8 million living species (物种), and that's just a fraction of what probably exists on Earth. With so many plants, animals, and other creatures covering the planet, it can be tough to figure out what type of spider is moving up your leg or what kind of bird is flying by.
2 v8 }& a: D; S" ?A soon-to-be-launchedWeb site might help.An international team of researchers has announced the creation of a Web-based Encyclopedia of Life (EoL).The project aims to catalog every species on Earth in a single, easy-to-use reference guide. , y! j2 v# [4 u, V7 b
To get the encyclopedia started, the creators will use information from scientific databases that already exist. And eventually, in special sections of the site, nonscientists with specialized knowledge will get to join in. Bird-watchers, for example, will be able to input which birds they've seen and where. The technology for this kind of tool has only recently become available. & m. B" Q6 G7 Z1 H
As the EoL develops, you might find it useful for school projects. The site will feature special pages for kids who are studying ecosystems (生态系统) in their neighborhoods. To make sure the encyclopedia is accurate, scientists will review much of the information added to it. People who visit the site will be able to chooseto leave out pages that haven't been reviewed. Another convenient feature of the EoL is that you'll be able to pick the level of detail you see to match your interests, age, and current knowledge. If you wanted to learn about bears for a science class report, for example, you could use the "novice" setting to get basic information about the animals. On the "expert" setting, on the other hand, you could get much more detailed information about the history, literature, and exploration of bears.

The coast of the State of Maine is one of the most irregular in the world. A straight line running from the southernmost coastal city to the northernmost coastal city would measure about 225 miles. If you followed the coastline between these points, you would travel more than ten times as far. This irregularity is the result of what is called a drowned coastline____(46). At that time, the whole area that is now Maine was part of a mountain range that towered above the sea. As the glacier (冰川) descended, however, it expended enormous force on those mountains, and they sank into the sea.
p, J0 l3 Z4 i& BAs the mountains sank, ocean water charged over the lowest parts of the remaining land, forming a series of twisting inlets and lagoons (咸水湖). The highest parts of the former mountain range, nearest the shore, remained as islands. ____(47) Marine fossils found here were 225 feet above sea level, indicating the level of the shoreline prior to the glacier.
0 e; i# ]' E, E! V8 \( JThe 2,500-mile-long rocky coastline of Marine keeps watch over nearly two thousand islands. Many of these islands are tiny and uninhabited, but many are home to thriving communities. Mt. Desert Island is one of the largest, most beautiful of the Maine coast islands. Measuring 16 miles by 12 miles. Mt. Desert was essentially formed as two distinct islands, _____(48): A$ V: R& E- Y( ^2 R
For years, Mt. Desert island, particularly its major settlement, Bar Harbor, afforded summer home for the wealthy. Recently though, Bar Harbor has become a rapidly growing arts community as well. But, the best part of the island is the unspoiled forest land known as Acadia National Park. Because the island sits on the boundary line between the temperate (温带) and sub-Arctic zones, the islands supports the plants and animals of both zones as well as beach, inland, and alpine (高山的) plants.____(49). The establishment of Acadia National Park in 1916 means that this natural reserve will be perpetually available to all people, not just the wealthy. Visitors to Acadia may receive nature instruction from the park naturalists as well as enjoy camping, cycling, and boating. Or they may choose to spend time at the archeological museum, learning about the Stone Age inhabitants of the island./ J$ X6 b. z1 B
The best view on Mt. Desert Island is from the top of Cadillac Mountain. ____(50) From the summit, you can gaze back toward the mainland or out over the Atlantic Ocean and contemplate the beauty created by a retreating glacier.
