The book of life

So far, scientists have named about 1.8 million living species（物种）, and that's a just a small part of what probably exists on Earth. With so many plants, animals, and other creatures coveting 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.

A soon-to-be-started Web site might help. An international team of researchers has announced the creation of Web-based Encyclopedia（百科全书）of life(EOL). The project aims to catalog every species on Earth in a single, easy-to-use reference guide.

To get the encyclopedia started, the creators will use information from scientific databases（数据库）that already exist. And eventually, in special sections of the site, nonscientist with specialized（专门的）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 become available.

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 choose to 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 want to see to match your interest, age, and 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.

It now takes years for scientists to collect all the data they need to describe and analyze species. The creators of the Encyclopedia of Life hope that their new tool will speed up that process.

36 A 文章第一段主要讲述的是，科学家只是将地球上少数的生物物种命名了，还有很多物种没有命名。接着作者使用蜘蛛和鸟的例子说明此观点，以显示地球上生物种类的繁多。答案为 A。

37 D 文章第二段最后一句"The project aims to catalog every species on Earth in a single，easy-to-use reference guide" ，说明"这个项目的目的是提供一个单一的，易于使用的生物分类参考指南"。答案为D。

38 C 文章第三段第一句话"To get the encyclopedia started, the creators will use information from scientific databases (数据库) that already exist"，说明"为了建立这个百科全书，创建者要使用现有的科学数据库"。答案为 C。

39 C novice 的原意是"新手"，并且文中的意思也是"使用新手设置"来得到有关动物的基本信息。答案为C。选项 A 意为"科学家"；选项 B 意为"创建者"；选项 D 意为"专家"。

40 A 文章第四段第三句话"To make sure the encyclopedia is accurate，scientists will review much of the information added to it"，说明"为了保证百科全书的准确性，科学家会复审其中大部分的信息"，而没有说是"全部的信息"。本题答案为 A。文章在不同的段落提到了其余各选项。
