Americans like to laugh and make jokes.(1)__________________________________.In the United States and a few other countries,the first day of April, the April Fool's Day,is a day devoted to such harmless practical jokes and an excuse for every American to fool his friends and neighbors.When I was a college student,our daily college newspaper,which was read by most of the people who live in the city near the college as well as by students,always had a special April Fools Edition.(2)______________________________________.Another year the paper falsely reported that a Russian submarine had been seen in the lake which is on the campus.It was surprising that many people believed these stories.But probably the most successful practical joke of all time was a national radio broadcast which said that the earth was being invaded by Mars.(3)____________________________________________.
