Review story #2--he took off, however/nevertheless, shouldn't (you shouldn't do it)

This story is part of a unit we do before we start "Look, I Can Talk More."  As always, corrections are welcomed.  I'd especially like comments on the punctuation.  Thanks!

Clark Kent estaba enamorado de Lois Lane, pero Lois estaba enamorada de Superman.  No debía ser un problema, porque Clark era Superman, pero sí había un problema.  Superman era una identidad secreta, y Lois no sabía que Clark era el Hombre de Acero.  Por eso, cuando miró a Clark, vio a un hombre tímido con gafas.  Y cuando miró a Superman, vio a un hombre superguapo con músculos y sin gafas.  Nunca se dio cuenta de que el uno era el otro.

Clark Kent was in love with Lois Lane, but Lois was in love with Superman.  It shouldn't be a problem, because Clark was Superman, but there was a problem.  Superman was a secret identity, and Lois didn't know that Clark was the Man of Steel.  So when she looked at Clark, she saw a shy man with glasses.  And when she looked at Superman, she saw a superhandsome man with muscles and without glasses.  She never realized that the one was the other.

       Un día, Clark decidió invitar a Lois a un restaurante elegante—en su disfraz de Superman.  Los dos llegaron y empezaron a comer.  Lo pasaban muy bien, sin embargo, Superman estaba nervioso.  Él quería revelar a su identidad a la chica.  Una voz interior le dijo—No debes hacerlo…--pero no lo escuchó. 

         One day, Clark decided to invite Lois to an elegant restaurant--in his Superman costume.  The two arrived and began to eat.  The were having a really good time; nevertheless, Superman was nervous.  He wanted to reveal his identity to the girl.  An inner voice said to him  "You shouldn't do it--but he didn't listen to it.

--Lois—le dijo Superman.  –Tengo algo muy importante que decir. 

"Lois", said Superman.  "I have something very important to say.

--¿Sí?—

"Yes?"

--Lois, mírame.--  La chica lo miró.  Superman se puso las gafas.

"Lois, look at me."  The girl looked at him.  Superman put on his glasses.

--¿Quién soy?—

"Who am I?"

--¡Pareces a Clark!  ¡Qué broma!—

"You look like Clark!  What a joke!"

Se quitó las gafas.  – ¿Y ahora?

He took off the glasses.  "And now?"

Lois se rió.  –Ahora eres  mi Superman otra vez.  ¡Qué cómico!—

Lois laughed.  "Now you are my Superman again.  How funny!

Pobre Superman.  Lois no se dio cuenta de que él era Clark.  Todavía estaba enamorada solamente de Superman.  Superman estaba contento, pero Clark estaba triste.  ¡Qué difícil cuando el uno era el otro!

Poor Superman.  Lois didn't realize that he was Clark.  She still was only in love with Superman.  Superman was happy, but Clark was sad.  How difficult when the one was the other!
