阅读理解。 The Book Of Life So far, scientists have named about 1.8 million living species (物种), and that's just a small number of what probably exists on Earth. With so many plants, animal, and other living things covering the planet, it can be tough to figure out what type of grass is growing by the roadside or what kind of bird just flew by. A soon-to-be-started Web site might help. An international term of researchers has announced the creation of Web-based Encyclopedia (百科全书) of Life (EoL). The project aims to list 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, non-scientists with specialized knowledge will come to help. Bird-watchers, for example, will be able to input what birds they've seen and where. To make sure the encyclopedia is accurate, scientists will review much of the information added to it. As the EoL develops, you might find it useful for school projects. The site will feature (以…为特色) special pages for kids who are studying ecosystems in their neighborhoods. 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 interests, age, and knowledge. It now takes years for scientists to collect all the data they need to describes and analyze species. The creators of the Encyclopedia of Life hope that their new fool will speed up that process. 1.

【简答题】鲁迅说:“描神画鬼,毫无对症,本可以专靠神思,所谓‘天马行空’地挥写了。然而他们写出来的却是三只眼、长颈子,也就是在正常的人体上增加了眼睛一只,拉长了颈子二三尺而已。”这段话说明,如神鬼之类的错误意识,也是客观世界的反映。( )
