              For a long time scientists believed that the human brain was （23）     developed by age 5and we were stuck with our gray cells for the rest of our lives．But our brain is a/an （24）     organ．
              Research finds that the brain can change（25）     and even create new connections all through our lives as we learn new skills!（26）    ，connections and areas of the brain that are less used （27）    ．The strength of the connections in the brain increases with the amount of practice．
              Every time you play a musical instrument，as your fingers glide over the instrument，your brain establishes important electrical （28）    ．As you try to figure out the right notes，you are exercising parts of the brain which are （29）     for language learning．When you（30）     your music，you are working yet other （31）     of the brain that help prevent memory loss．
              The （32）      activities required for learning and playing music help to build connections in the brain between otherwise （33）     parts．
              Why is this important？（34）     taking a new，unfamiliar route to school．It will take a few attempts （35）     you figure out the best shortcut to your destination．The brain works in the same way．Creating new connections can help us （36）     our brain to focus on （37）     ways of learning and storing information that is important for us．
              So the next time your mother （38）     you to practice your music，you are not doing her a （39）    ---you are （40）     strengthening and re-writing your brain for the future!

            • 3． Lost forever
              Most people have heard about Didus ineptus，or the dodo，as it is more commonly known．It was the flightless，long-extinct（灭绝的）member of the dove family that lived in the Indian Ocean island of Mauritius．The name"dodo"comes from the Portuguese and means"a person who is foolish"；（31）    ，to call someone a"dodo"（32）    their stupidity．The dodo was a foolish creature about the size of a turkey and was easily fooled by sailors who tapped on trees to（33）    its attention．It would come（34）     towards the sound and was easily caught and whisked on board ship to become a valuable source of fresh，but tough meat．
              Another expression to appear from the（35）    bird's situation is to say that something is"as dead as a dodo"，which means long since dead，very much（36）    ，or deserted．Of the many animals that people have removed from the face of the earth，the dodo has probably made the greatest contribution to our（37）    ．
              Another less well-known but（38）    extinct bird is Aepyornis maximus，more commonly known as the elephant bird of Madagascar．This creature（39）    a very thickset，three-metre-tall emu（鸸鹋）（40）    over half a ton and is thought to be the largest bird that ever lived．It was big in every way，even its eggs were extremely large．An elephant bird egg could measure up to ninety centimetres in diameter and（41）     nine liters of liquid，about 200 ordinary chicken eggs．The eggs were in fact three times larger than dinosaur eggs．
                It's hard to imagine how impressive the elephant bird must have been as it walked about proudly in its natural habitat．For thousands of years its size（42）    was enough to scare the meat-eating animals．（43）    it was a flightless bird，its sharp claws and powerful neck and beak ensured it could look after itself-that is，up until the Europeans arrived on Madagascar．They not only hunted elephant birds for food but began（44）    their eggs as gifts．Sadly it was made（45）    around I700，and the world became a much poorer place because of it
