       Spiderman is one of the most famous comic book heroes of all time. He was created by Stan Lee in 1963

and was first introduced to the world in the pages of Marvel comic books. 

       Spiderman's story is the story of Peter Parker, a child who lost his parents and lives with his aunt and

uncle. Peter is a shy, quiet boy wearing glasses and has few friends. One day, on a high school class trip to a

science lab, he gets bitten by a special spider. Soon Peter realizes he has amazing powers: he is as strong and

quick as a spider and also has a type of sixth sense. He no longer needs his glasses and he can use his super

power to fly through the city streets! Remembering something his Uncle Ben has told him, that "with great

power, there must also come great responsibility (责任)," Peter decides to use his powers to fight enemies who

do cruel things to people. And so, Spiderman is born.

       Life is not easy for Peter even though he is a superhero. He is in love with Mary Jane but cannot tell her

about his amazing powers. Besides, his best friend Harry hates Spiderman! Peter is also short of money and

time. He has to sell photos of Spiderman (himself!) to a newspaper and he keeps losing his other jobs because

he's so busy saving people! Yet he has to fight different kinds of cruel enemies.

阅读下列文言文,完成后面题目。

  ①庆历四年春,滕子京谪守巴陵郡。越明年,政通人和,百废具兴。乃重修岳阳楼,增其旧制,刻唐贤今人诗赋于其上。属予作文以记之。
