Many people say dolphins are intelligent． They seem to be able to think， understand and learn things quickly． But are they as smart as humans， or are they more like cats and dogs？ Dolphins use their brains quite differently from the way humans do． But scientists say dolphins and humans are very similar in some ways． How？
Like humans， every dolphin has its own "name"． The name is a special whistle （哨声）． Each dolphin chooses a specific （特有的） whistle for itself， usually by its first birthday． Dolphins are like people in other ways， too． They "talk" to each other about a lot of things﹣such as their age， their feelings， and finding food． They also use a system of sounds and body language to communicate． Understanding dolphin conversation is not easy for humans． No one "speaks dolphin" yet， but some scientists are trying to learn．
Dolphins are also social animals． They live in groups called pods， and they often join othersfrom different pods to play games and have fun﹣﹣just like people． Scientists believe playing together is something only intelligent animals do．
Dolphins and humans are similar in another way： both species make plans for getting things they want． In the seas of southern Brazil， for example， dolphins use an intelligent plan to get food． When there are fish near a boat， dolphins signal （发信号） to the fishermen to put their nets in the water． Using this method， the men can catch a lot of fish． Why do dolphins help the men？ There is an advantage for them ：they get to eat some of the fish that escape （逃脱） from the net．

"Colour" and "color"， "favourite" and "favorite"， "honour" and "honor"…Have you ever wondered why Americans spell those words without a "u"？Is it because they are lazy？
Of course not.In fact，the difference in spelling was started by Noah Webster（1758﹣1843）.He was a teacher who reformed（改革）English to make American identity（特征）stronger.Linguists（语言学家）celebrate his birthday on October 16 every year.
After the Revolutionary War（1775﹣1783），Webster believed that Americans should have their own dictionary，rather than rely on British dictionaries.
He dropped the British "u" in some words.And he changed "centre" into "center" for children to learn English by spelling words more like what they sounded.He used "subway" instead of British word "underground".Some other examples are "soccer" and "football"， "fall" and "autumn".
Webster wasn't shy about expressing his opinions.In defining（定义）preposterous （unreasonable），he wrote： "A republican government in the hands of female is preposterous."
Webster spent 28 years on the project before completing the 70，000﹣word dictionary with his American﹣style spelling in 1828.He also added local words.
His dictionary was widely used in schools.Linguists believed it helped a new country achieve unity（统一）and cultural independence at a time when most people cared about political freedom.
"He was the creator of our language and the creator of American identity，" said Joshua Kendall，who is working on a book about Webster. "He at last brought us together through our language."
