The Book of Life

So far, scientists have named about 1.8 million living species(物种),and that's just a small part 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.
A soon-to-be-launched Web site mighit help. An international team of researchers has announced the
creation of a 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 referenice 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 , nonscientists with specialized(专门的)
knowledge will get to join in Bird-watchers,for example,will be able to input which birds they'ye seen and
where.The technology for this kind of tool has only recently 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'11 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.
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 that process.
选项 At the starting stage the EoL will get information from________. A:all the Web sites available B:the existing scientific databases C:databases built up by its creators D:nonscientists with specialized knowledge
答案 B
解析 由文章内容可知,文章开头运用“蜘蛛”和“鸟”的例子主要说明地球上生物的种类太 多了。
根据第二段的最后一句话可知正确答案。
由第三段的第一句话可知答案。
novice在文中的意思为“新手,初学者”,选项中的beginner符合题意。
由文中第一句话可知“科学家已经命名1.8百万种物种了”,而不是“仅仅一小部分”, 其他选项在文中都能找到依据。第二篇 文章主要讲一些科学家,设计者和艺木家为帮助一个没有电的地区设计了一种“便携灯”及 这种灯的工作原理。
