Today, roller skating is easy and fun. But a long time ago, it wasn’t easy at all. Before 1750, the idea of skating didn’t exist. That changed because of a man named Joseph Merlin. Merlin was a person who liked playing the violin and was full of ideas and dreams. People called him a dreamer.
One day Merlin received an invitation to a fancy dress ball (化装舞会). He was very pleased and a little excited. As the day of the party came near, Merlin began to think how to make a grand entrance at the party. He came up with an idea. He thought everyone would be attracted by him if he could skate into the room.
Merlin tried different ways to make himself roll. Finally, he decided to put two, wheels under each shoe. These were the first rolled skates. Merlin was very proud of his invention and dreamed of arriving at the party on wheels while playing the violin.
On the night of the party Merlin rolled into the room, playing the violin. Everyone was amazed to see this. There was just one problem. Merlin had no way to stop his roller skates. Suddenly he ran into a huge mirror hanging on the wall. It fell down and broke into pieces. Nobody forgot Merlin's entrance for a long time.

Explosive sound and energy
ROCK music didn’t exist 60 years ago． 1 Someone didn’t just wake up and invent rock．So, how did it happen? What is rock?Although impossible to strictly define, it’s generally recognized that rock music was born in 1950s America． 2 At this time, early “rockers”were mixing the country music of white America with the rhythm and blues sound loved by the black US citizens．The result was rock‘n’ roll．The record most commonly considered as the beginning of the rock ‘n’ roll period is Bill Haley & The Comets’1954 recording of “Rock Around the Clock”． 3 Elvis’s 1950s recordings established the basic language of rock ‘n’ roll; his explosive stage presence set standards for the music’s visual image, while his voice was powerful and interesting．
4 Despite the different directions and sound of rock bands over the last 50 years, there is something common to all the greats：a charming lead vocalist, a talented guitarist full of energy and creativity, a bassist with cool indifference and a drummer．
For most of its life, rock has been split into different parts, creating new styles every few years－giving birth to a never-ending number of sub-genres． 5 Rock is a generic term, but it’s exciting that it can now mean so many different things．
A．Rock is my favorite and I’ll be a popular singer．
B．Now, it’s one of the world’s most popular genres．But musical styles don’t spring up overnight．
C．Rock had a specific sound and image for only a few of its early years．As time went by, the genre began to place equal emphasis on skills and pushing the boundaries of the music．
D．In fact, in the West, musically speaking, the years 1953～1955 are known as the rock ‘n’ roll years．
E．As a result, “rock”has been used to describe everything from bands playing catchy rhythms to groups based on tuneless, noisy guitars．
F．Rock music will be held in our school if we send an invitation to the band．
G．But it was Elvis Presley, known as “The King of Rock and Roll”, who really popularized the new sound throughout America and the Western world．

查看习题详情和答案>>On May 21, 2000, some American scientists were working at the computers to look for information they needed .
