Failure，they say, is the best teacher. We learn and have more confidence in what we know through trial and error, which onetime or another has   36  failure. You don’t have to  37  your failure if what you really want to achieve is  38  .

   For every  39  achievement, there have been one or more failures. But those who we call successful are those who  40  to accept failure and believe success is the other side of failure. The incandescent light (白炽灯) was  41  after 1,000 failures. If Thomas Edison had  42  after he tried 100 times without the desired result, what would have been the  43  of such effort?

   Any time you see products and new inventions, think in terms of failures that are not accepted. 44  everything in a microform (微缩过程) today is a result of failure not accepted.

   Any time your effort is not bringing a(n)  45  result, you don’t have to call it a failure. Call it a challenge. What is the  46  between the two? One is negative, the other is  47 ; one demotivates , the other motivates.

   What you need is positive thinking and motivation to  48  success. Failure is an end thing; 49  is an open thing. Failure means there is no way out, no alternative, but a challenge is a question mark  50  another way out of the situation, an alternative  51  to the problem.

   Keep dreaming, keep moving; that is the solution to success.

   A wise man once said if you cannot fly, run. If you cannot  52  ,walk. If you cannot walk, crawl; just keep moving. If you fall down, you have to  53  and start moving. If not, other people will step on you towards their  54  . What you call failure and  55  is what someone will step into with just a little additional effort to reach achievement.

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，fungi，and other organisms covering the planet，it can be tough to figure out what type of spider is crawling up your leg or what kind of bird just flew by．

A soon-to-be-launched Website might help．An international team of researchers has announced the creation of a Web ― based Encyclopedia of Life （EOL）．The project aims to catalogue 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 that already exist．And eventually，in special sections of the site，nonscientists with specialized knowledge will join．Gardeners，for example，will be able to record the dates that their flowers first bloom each year．Bird-watchers will be able to input which birds they’ve 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 have special pages for kids who are studying ecosystems 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 skip pages that haven’t been reviewed．

Another convenient characteristic 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 polar 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 polar 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．

Keep an eye on www.eol.org．Pages will begin to go up sometime next year，and you might find them useful for your school reports．The EOL team might have the basics for all 1.8 million entries online as early as 2017．Someday，you might add your own notes.
