Pizza is the world's favorite fast food.We can eat it everywhere — at home，in restaurants，or on streets.（1）There are many stories about the history of pizza. Here is one of them.It says pizza came from China.
   In the 1200s，Marco Polo came to China from Italy.There he tasted a Chinese scallion（蔥） pancake.（2）這個(gè)煎餅嘗起來(lái)如此美味以至于他非常喜歡它。 After he went back to Italy，he missed the pancakes very much.（3）But he didn't know how to make them.
   One day，Marco Polo met a cook at a friend's dinner party.He described what Chinese scallion pancakes were like.And he wanted the cook to make one for him.The cook did as he said.But it was not an easy job.（4）He found it was very difficult to put the scallion into the pancake. "How about putting it on the pancake？" Marco Polo said.The cook did so，and made a nice "pancake" at the party.People enjoyed the new dish a lot.
   （5）這個(gè)廚師也對(duì)"煎餅"感興趣。 When he went back home，he put meat and vegetables on it.This became today's pizza later.
