共用题干第二篇The Book of LifeSo far,scientists have named about 1.8 million living species,and that's just a fraction of what proba- bly exists on Earth.With so many plants,animals,and other creatures covering the planet,it can be toughto 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 might help. An international team of researchers has announced thecreation of a Web-based Encyclopedia of Life(EoL).The project aims to catalog every species on Earth in asingle,easy-to-use reference guide.To get the encyclopedia started,the creators will use information from scientific databases that alreadyexist.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 technologyfor 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 forkids who are studying ecosystems（生态系统）in their neighborhoods. To make sure the encyclopedia isaccurate,scientists will review much of the information added to it. People who visit the site will be able tochoose 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 see to matchyour interests,age,and current knowledge.If you wanted to learn about bears for a science class report,forexample,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.Thecreators of the Encyclopedia of Life hope that their new tool will speed that process."Spider" and"bird"mentioned in Paragraph 1 are examples to illustrate_______________.A:animals are people's friendsB:there are numerous living species on EarthC:it is easy to see spiders and birdsD:there are many types of spiders and birds
