B
It is natural that children are curious about the world around them. For example, they want to know how their hearts beat. They want to know why the ocean water tastes salty.
As children grow up, they become curious about different kinds of things. When they are babies, they are interested in the parts of their bodies and in the smiles of their mothers. They become interested in the physical world around them: the plants, the animals, the sky. Later, they become interested in the things that people have made: wheels, bicycles, cars. And when they are adults, their curiosity continues. Sometimes this curiosity leads to a career (生涯、职业) in science.
Scientists spend their lives trying to find out about the world．Those who work with the earth sciences study the earth, the oceans, and the skies. Other scientists who study living things work with the biological sciences. A third group of scientists study the physical sciences, e. g. physics, chemistry .
These scientists have already discovered a lot about our world．For example, they tell us why your heart beats fast when you run. They say that when you are quiet, your heart normally beats sixty-five or seventy-five times a minute. Your heart is a pump (泵) that pumps blood to all parts of the body. The blood carries oxygen and nutrition. When you run, your muscles work very hard and use the nutrition that the blood carries to them. The muscles need oxygen, too . So your brain sends a signal to the heart. The signal means that the muscles need more nutrition and oxygen. Then the heart beats fast and sends blood quickly to the muscles. It may beat 90 to 140 times a minute.
Of course, scientists cannot answer all of our questions. If we ask, “Why does the ocean water taste salty” scientists will say that the salt comes from rocks. When a rock gets very hot or very cold, it cracks. Rain falls into cracks. The rain then carries the salt into the earth and into the rivers. The rivers carry the salt into the ocean. But then we ask , “What happens to the salt in the ocean? The ocean does not get saltier every year.” Scientists are not sure about the answer to this question.
We know a lot about our world, but there are still many answers that we do not have, and we are curious.

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．
