   A learned man has always a lot of riches in himself.

   Simonides,a famous Greek poet, once made a tour around the well－known cities of Asia. Years later, he decided to 1to his native land by sea.

    However,he hoarded on a ship, which got 2in a terrible storm. Together withits own poor condition, the ship began to 3 into the sea. Somepassengers was busy 4together their bags, and others their 5belongings.To everyone's surprise, Simonides was a(n)6. One who was 7curious, asked, “Are you going to save 8 of your property, Simonides？” He made a reply, “All my possessions are 9 me.”

    While a few made their 10 by swimming, the majority, being weighed down bytheir burdens, disappeared in the sea. 11 ， some thieves made their appearance, and stole12the few lucky people had saved, leaving them nothing.

     Clazomenae,an ancient city, chanced to be near the beach. Here lived a wealthy man 13the pursuits (追求) of literature. Hehad often read the poems of Simonides, and was a very great14 ofhim though he had never seen Simonides. 15 ， Simonides was saved by this man shortly after he got to thebeach.

          Wisdom teeth are normally the last teeth to appear.This usually happens when people are in their late teen years or early twenties，in other words，when they are older and wiser.

          Wisdom teeth can grow into place normally and never cause a problem.But often there is not enough room for them in the mouth；they might crowd other teeth.Sometimes they even push sideways through the gums (齿龈)．

          An impacted wisdom tooth is one that fails to completely rise through the gums.Wisdom teeth that only partly break through can leave space for bacteria to enter around the teeth.Infection (感染) is a risk in these cases.

         Wisdom teeth that are not well lined and become impacted are often removed.The American Dental Association says removal is generally advised when wisdom teeth only partly break through the gums.Removal is also advised if there is a chance that wisdom teeth ate poorly lined.The best time to remove is before the teeth cause any problems or pain.Young adults are the best candidates for wisdom teeth removal.

         But why do we have wisdom teeth if we often need to get them removed？One theory has to do with our diets.Scientists say the diet of ancient humans probably required more chewing teeth.Life was probably a little rougher on the teeth back then，too.So it was good to have extras.
