Выпишите все глаголы из текста и определите их видовременную

In his plays, Shakespeare revealed a very wide knowledge of many areas of life. The characters in his plays discuss many different topics, often with the knowledge of experts. But what is even more impressive about these plays is Shakespeare’s use of the English language. His vocabulary was very large, and Shakespeare seems to have introduced many words to the language! Also, many of the phrases that are said by Shakespeare’s characters are now used in everyday conversation. Today, writers often use quotations from Shakespeare’s plays in their own works.
